Example5

The following example is intended to help you compare the cost of investing in the Contract with the cost ofinvesting in other variable annuity contracts. These costs include Contract Owner transaction expenses, Contractfees, separate account annual expenses, and Portfolio fees and expenses. The following example assumes that youinvest $10,000 in the Contract for the time periods indicated and that your investment has a 5% return each yearand assumes both the minimum and the maximum fees and expenses of the Portfolios. Although your actual costsmay be higher or lower, based on these assumptions, your costs would be:

Years

1 3 5 10

If you surrender your Contract at the end of theapplicable time period with

Minimum Portfolio Expenses: $ 712 $ 873 $1,032 $1,791

Maximum Portfolio Expenses: $1,027 $1,823 $2,620 $4,894

If you annuitize your Contract at the end of theapplicable time period with

Minimum Portfolio Expenses: $ 712 $ 873 $1,032 $1,791

Maximum Portfolio Expenses: $1,027 $1,823 $2,620 $4,894

If you do not surrender your Contract at end of theapplicable time period with

Minimum Portfolio Expenses: $ 153 $ 474 $ 818 $1,791

Maximum Portfolio Expenses: $ 486 $1,461 $2,439 $4,894

Notes to Fee and Expense Tables:1 In each Contract Year, you may surrender without a surrender charge up to 10% of the Accumulated Value existing at the timethe first surrender is made in a Contract Year; only the amount in excess of that amount (the “Excess Amount”) will be subjectto a surrender charge. A surrender charge is deducted if a full or partial surrender occurs during the first six Contract Years. Thesurrender charge is 6% during the first Contract Year and decreases by 1% each subsequent Contract Year. No surrender charge isdeducted for surrenders occurring in Contract Years seven and later. The surrender charge also will be deducted if the annuitypayments begin during the first six Contract Years, except under certain circumstances as described in Surrender Charge(Contingent Deferred Sales Charge).2 A $30 annual administrative charge is deducted on each Contract Anniversary only if, on that Contract Anniversary, the totalof premiums paid under the Contract minus all prior surrenders is less than $5,000 and the Accumulated Value is less than$5,000. The $30 fee is a Contract charge and is deducted proportionately from the Subaccounts and the Fixed Account thatmake up the Contract’s Accumulated Value.3 The current charge for mortality and expense risk fees is equal to an annual rate of 1.10%, and we guarantee that this chargewill never exceed an annual rate of 1.25%. See Charges and Deductions—Mortality and Expense Risk Charge. A contract pendingpayout due to a death claim is charged based on the average daily net assets of the Variable Account and is equal to an annualrate of 0.95%.4 Thrivent Financial has agreed to reimburse certain expenses other than the advisory fees for certain Portfolios. After takingthese contractual and voluntary arrangements into account, the range (minimum and maximum) of total operating expensescharged by the Portfolios would have been 0.25% to 1.20%. The reimbursements may be discontinued at any time.5 For this example, the following assumptions are used: 1.25% mortality and expense risk charge and portfolio operatingexpenses ranging from 3.61% to 0.25%.

Allocation of Premiums. You may allocatepremiums under the Contract to one or more of theSubaccounts of the Variable Account and to the FixedAccount. Some of the Subaccounts may be unavailablein some states.

The Accumulated Value of the Contract in theSubaccounts and, except to the extent fixed amountannuity payments have been elected, the amount ofannuity payments will vary, primarily based on theinvestment experience of the Portfolios whose sharesare held in the Subaccounts designated. Premiumsallocated to the Fixed Account will accumulate at fixedrates of interest declared by us, and will never be lessthan an effective rate of 3% per year.

Premiums will be allocated among the Subaccounts andthe Fixed Account according to your allocationinstructions, at the end of the Valuation Period inwhich we receive the premium.

Surrenders. If a Written Notice from you requesting asurrender is received on or before the AnnuityCommencement Date, we will pay to you all or part ofthe Accumulated Value of a Contract after deductingany applicable surrender charge. Partial surrenders mustbe for at least $200, and may be requested only if theremaining Accumulated Value is not less than $1,000.Under certain circumstances the Contract Owner maymake surrenders after the Annuity CommencementDate.

Transfers. On or before the Annuity CommencementDate, you may request the transfer of all or a part ofyour Contract’s Accumulated Value to otherSubaccounts or to the Fixed Account. The total amounttransferred each time must be at least $200 (unless thetotal value in the Subaccount or the Fixed Account isless than $200, in which case the entire amount may betransferred). We reserve the right to limit the number oftransfers in any Contract Year, although we will alwaysallow at least 12 transfers a year. With respect to theFixed Account, transfers out of the Fixed Account arelimited to only one each Contract Year and must bemade on or within 45 days after a Contract Anniversary.

Annuity Provisions

You may select an annuity settlement option or options,and you may select whether payments are to be madeon a fixed or variable (or a combination of fixed andvariable) basis. See Annuity Provisions for more detail.

Exchange Program

From time to time, we may offer programs for certainvariable annuities issued by Thrivent Financial or ouraffiliates, to be exchanged for the contract described inthis prospectus. Such exchange offers will be madeavailable only for contracts that have not yet startedmaking annuity payments. Any new contract resultingfrom such exchange will have the same Issue Date as theContract being exchanged only for purposes ofcalculating surrender charges, if applicable. You shouldcarefully consider whether an exchange is appropriatefor you by comparing the death benefits, living benefitsand other guarantees that are provided by the contractyou currently own to the benefits and guaranteesprovided by the new contract being offered. You shouldalso compare the fees and charges of your currentcontract to the new contract being offered as they maybe higher than your current contract. The programs weoffer will be made available on terms and conditionsdetermined by us and any such programs will complywith applicable law. We believe the exchanges should betax free for federal income tax purposes; however, youshould consult your tax advisor before making any suchexchange.

investments held, fund expenses, and other factors allcontribute to differences in Portfolio performance. Forall of these reasons, you should expect investmentresults to differ. In particular, certain Portfolios availableonly through the Contract may have names similar toportfolios not available through the Contract. Theperformance of a Portfolio not available through theContract does not indicate performance of the similarlynamed Portfolio available through the Contract.

Before selecting any Subaccount, you shouldcarefully read the accompanying prospectus forthe Fund attached to this prospectus and foundin the back of this book. You shouldperiodically consider your allocation amongSubaccounts in light of current marketconditions and your investment goals, risktolerance and financial circumstances. TheFund prospectus provides more completeinformation about the Portfolios of the Fund inwhich the Subaccounts invest, includinginvestment objectives and policies, risks,charges, and expenses.

Shares of the Fund are sold to other Portfolios of theFund, to other insurance company separate accounts ofours and of our wholly owned subsidiary, Thrivent LifeInsurance Company (“Thrivent Life”), and to otherinsurance company separate accounts not affiliated withus. The Fund may, in the future, create new Portfolios. Itis conceivable that in the future it may bedisadvantageous for both variable annuity separateaccounts and variable life insurance separate accountsand for Thrivent Life and us to invest simultaneously inthe Fund, although we do not foresee any suchdisadvantages to either variable annuity or variable lifeinsurance contract owners. The Fund’s managementintends to monitor events in order to identify anymaterial conflicts between such Contract Owners and todetermine what action, if any, should be taken inresponse. Material conflicts could result from, forexample:

� Changes in state insurance laws;

� Changes in Federal income tax law;

� Changes in the investment management of theFund; or

� Differences in voting instructions between thosegiven by the Contract Owners from the differentseparate accounts.

If we believe the responses of the Fund to any of thoseevents or conflicts insufficiently protects ContractOwners, we may take appropriate action on our own.Such action could include the sale of Fund shares byone or more of the separate accounts, which could haveadverse consequences.

The Fund is a Minnesota corporation registered with theSEC under the 1940 Act as an open-end managementinvestment company (commonly called a “mutualfund”). That registration does not involve supervisionby the SEC of the management or investment practicesor policies of the Fund.

The Variable Account will purchase and redeem sharesfrom the Fund at net asset value. Shares will beredeemed to the extent necessary for us to collectcharges under the Contracts, to make payments uponsurrenders, to provide benefits under the Contracts, orto transfer assets from one Subaccount to another asrequested by Contract Owners. Any dividend or capitalgain distribution received from a Portfolio of the Fundswill be reinvested immediately at net asset value inshares of that Portfolio and retained as assets of thecorresponding Subaccount.

THE CONTRACT••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

Allocation of Premium

We will allocate the premiums among the Subaccount(s)and/or the Fixed Account according to the instructionsyou provided in your application for the Contract orsubsequently. We reserve the right to limit the numberof allocations to subaccounts.

The allocation percentages which you select must be inwhole numbers and their sum must be 100%. Wereserve the right to adjust allocation percentages toeliminate fractional percentages. Premiums which youpay are allocated at the end of the Valuation Period inwhich we receive them using the allocation percentagesyou have specified. You may change the allocationpercentages for future premiums without charge and atany time by giving us Written Notice or over thetelephone if we receive proper authorization from you.Any change will apply to all future premiums unless yourequest another change.

The values in the Subaccounts of the Variable Accountwill vary with the investment experience of thecorresponding Portfolios. You bear the entireinvestment risk of the amounts allocated toSubaccounts of the Variable Account. You shouldperiodically review your allocations of premiums inlight of market conditions and your overall financialobjectives.

Accumulated Value of Your Contract

On or before the Annuity Commencement Date, yourContract’s value is expressed as its Accumulated Value.Your Contract’s Accumulated Value is the sum of theaccumulated values in Subaccounts and the FixedAccount.

Your Contract’s Accumulated Value will reflect theinvestment experience of the chosen Subaccounts, anyamount of value in the Fixed Account, any premiumsthat you pay, any surrenders you make, and any chargeswe assess in connection with the Contract. There is noguaranteed minimum Accumulated Value, and, becausea Contract’s Accumulated Value on any future datedepends upon a number of variables, it cannot bepredetermined.

Subaccount Valuation

On any Valuation Day, the Accumulated Value of yourinvestment in a Subaccount is equal to the number ofAccumulation Units attributable to that Subaccountmultiplied by the Accumulation Unit Value for thatSubaccount. On any day that is not a Valuation Day, theAccumulated Value for a Subaccount will be determinedon the next Valuation Day.

Accumulation Units. Transactions in and out of aSubaccount are made by crediting or reducing theAccumulation Units of the Subaccount.

We credit your Contract with Accumulation Units in aSubaccount when:

� You allocate premiums to that Subaccount;

� You transfer Accumulated Value into thatSubaccount from another Subaccount or the FixedAccount.

We reduce the Accumulation Units in a Subaccountwhen:

� You transfer Accumulated Value out of thatSubaccount into another Subaccount or the FixedAccount;

� You make a surrender from that Subaccount; or

� We deduct all or part of the administrative chargefrom that Subaccount.

Accumulation Unit Value. A Subaccount’sAccumulation Unit Value is the unit price that is usedwhenever we credit or reduce Accumulation Units of theSubaccount. We re-determine the Accumulation UnitValue for each Subaccount at the end of each ValuationPeriod. At the end of each Valuation Period, theAccumulation Unit Value for a Subaccount is equal to(a) multiplied by (b) where:

(a) Is the Accumulation Unit Value for thatSubaccount at the end of the prior ValuationPeriod.

(b) Is the Net Investment Factor for thatSubaccount for that period.

Net Investment Factor

The Net Investment Factor for a Subaccount measuresinvestment performance of that Subaccount. The NetInvestment Factor for a Subaccount for a ValuationPeriod is determined by dividing (a) by (b) and thensubtracting (c) where:

(a) Is the sum of:

(i) The net asset value per share of thecorresponding Portfolio of the Subaccountat the end of the Valuation Period; plus

(ii) The per share amount of any dividend orcapital gain distribution made by thePortfolio if the “ex-dividend” date occursduring the Valuation Period; plus or minus.

(iii) A per share charge or credit for any taxesreserved for that we determine to be aresult of the investment operation of thePortfolio.

(b) Is the net asset value per share of thecorresponding Portfolio of the Subaccount atthe end of the prior Valuation Period.

(c) Is the mortality and expense risk charge wededuct for each day in the Valuation Period andis based upon the total Accumulated Value inthe Subaccount. The mortality and expense riskcharge is currently 1.10% and guaranteed neverto exceed 1.25%.

Minimum Accumulated Value

We require your Contract to maintain a minimumAccumulated Value. The amount which must bemaintained depends on your premium paying history asfollows:

(1) At the end of any 24-month period in whichyou pay no premiums, your Accumulated Valuemust be at least $1,000 after all Contractcharges have been applied.

(2) If you pay at least one premium every24-months, we require only that theAccumulated Value always be sufficient tocover the Contract’s administrative charge.

If we know that your Contract will not meet theserequirements on an upcoming Contract Anniversary, wewill notify you 60 days before that anniversary andinform you of the minimum dollar amount which youmust pay to keep the Contract in force. If you fail to payat least that amount, we will terminate your Contracton the Contract Anniversary. If we do so because yourContract failed to meet Requirement (1) above, we willpay you the remaining Accumulated Value. If yourContract fails to meet Requirement (2) above, yourContract terminates without value.

Death Benefit Before the AnnuityCommencement Date

If the Annuitant dies before the AnnuityCommencement Date, the beneficiary will be entitled toreceive the Contract’s death benefit.

The amount of the death benefit will be the greatest of:

� The Accumulated Value on the date we calculatethe death benefit;

� The sum of all premiums we received for theContract, less the amount of all partial surrenders(including any applicable charges) which youmade; and

The Minimum Death Benefit Dates occur every six yearson the Contract Anniversary.

We calculate the death benefit at the end of theValuation Period during which we receive at our ServiceCenter satisfactory proof of the death of an Annuitant.Any amount of the death benefit in excess of theAccumulated Value will be allocated to the Subaccountsand the Fixed Account according to the ratio of theAccumulated Value in each to the Accumulated Value inthe Contract.

increase or decrease daily and are not guaranteed for aminimum dollar amount. Surrender charges do notapply to death proceeds.

If the beneficiary requests a single sum payment, we willpay the death proceeds within seven days after the datewe calculate them. If the beneficiary requests asettlement option, it must be an option that you couldhave selected before the Annuity Commencement Date,and the option must provide that either:

(1) The principal and interest are completelydistributed within five years after the date ofdeath; or

(2) If the beneficiary is a natural person,distribution of the principal and interest ismade by means of a periodic payment whichbegins within one year after the date of deathand is not guaranteed for a period whichextends beyond the life expectancy of thebeneficiary.

Any proceeds not subsequently withdrawn will be paidin a lump sum on the date five years after the date ofdeath.

If an Annuitant dies before annuity payments begin andthat Annuitant’s Spouse is the sole primary beneficiary,he or she may, to the extent permitted by law and theContract, elect to continue the Contract in force, inwhich case the surviving Spouse will become and betreated as the Annuitant and owner effective on thedate that the death proceeds are calculated (“ExchangeDate”). Any amount of death proceeds in excess of theAccumulated Value of the Contract will be allocated tothe Subaccounts and the Fixed Account according to theratio of the Accumulated Value in each to theAccumulated Value of the Contract. Where allowed bythe Contract, the Spouse will have 60 days from thedate we receive proof of your death in which to elect toreceive proceeds or to continue the Contract. If anelection to receive death proceeds or to continue theContract is not made within 60 days, the survivingSpouse will be deemed to have elected to continue theContract effective on the Exchange Date. If thesurviving Spouse elects to continue the Contract, thedeath benefit will be determined according to yourContract based on the Accumulated Value on theExchange Date.

If your Contract was issued in connection with aQualified Plan, additional restrictions on the manner ofpayment of the death benefit may apply. Any suchrestrictions will be stated in the Contract or the plandocuments. Purchasers acquiring contracts pursuant toQualified Plans should consult qualified pension or taxadvisers.

Death Benefit After the AnnuityCommencement Date

If the Annuitant dies while we are paying you anannuity income under a settlement option, any deathbenefit payable will depend on the terms of thesettlement option. If a death benefit is payable, thebeneficiary may elect to receive the proceeds in theform of a settlement option, but only if the paymentsare paid at least as rapidly as payments were being paidunder the settlement option in effect on the date ofdeath. If your Contract was issued in connection with aQualified Plan, additional restrictions on the manner ofpayment of the death benefit may apply.

Surrender

On or before the Annuity Commencement Date, youmay surrender all or part of your Contract’sAccumulated Value by completing an approvedsurrender form and sending it to our Service Center. Thesurrender or partial surrender will not be processed untilwe receive your surrender request at our Service Center,in good order. Any surrender which you request will bemade at the end of the Valuation Period during whichthe requirements for surrender are completed. We willpay you the proceeds from a surrender within sevendays after the surrender is made.

The proceeds will be the amount surrendered less anysurrender charge. See Charges and Deductions—SurrenderCharge (Contingent Deferred Sales Charge).

A surrender reduces your Accumulated Value by theamount surrendered. For amounts surrendered from aSubaccount, this is done by selling Accumulation Unitsof the Subaccount. For partial surrenders, we allocatethe surrender among the Subaccounts and the FixedAccount so that all accounts are reduced in value by thesame percentage. With our approval, you may specify adifferent allocation for a partial surrender. If you have

requested that a systematic partial surrender should beallocated to a specific Subaccount and the value in thatSubaccount is less than the amount of the allocation,we will allocate the partial surrender among theSubaccounts and the Fixed Account so that all accountsare reduced in value by the same percentage.

A partial surrender must be at least $200 (except wherepartial surrender proceeds will be used to makepayments on another Thrivent product) and must notreduce the remaining Accumulated Value to less than$1,000. (If the amount you request as a partial surrenderwould reduce the remaining Accumulated Value to lessthan $1,000, we may contact you to determine whetheryou would like a partial surrender of an amount thatwould result in remaining Accumulated Value of at least$1,000 or whether instead you would like to make a fullsurrender of your Contract. If we are unable to contactyou within seven days, we reserve the right to treat yourrequest as a request for a full surrender.) When yourequest a partial surrender, you specify the amountwhich you want to receive as a result of the surrender. Ifthere are no surrender charges or withholding taxesassociated with the surrender, the amount surrenderedwill be the amount which you request. Otherwise, theamount surrendered will be the amount necessary toprovide the amount requested after we apply thesurrender charge and any withholding taxes. You maymake partial surrenders by telephone if we receiveproper authorization from you. (Contracts used in atax-sheltered annuity under Section 403(b) of theInternal Revenue Code will be subject to certainrestrictions regarding surrenders and may require anemployer signature. See Federal Tax Status—QualifiedPlans.) Any surrender which you request will be made atthe end of the Valuation Period during which therequirements for surrender are completed. We will payyou the proceeds from a surrender within seven daysafter the surrender is made.

After the Annuity Commencement Date, your Contractdoes not have an Accumulated Value which can besurrendered. However, if you are receiving annuitypayments under certain settlement options, surrendermay be allowed. Surrender is not allowed if yoursettlement option involves a life income or if you agreednot to revoke or change the option once annuitypayments begin. For other settlement options, theamount available for surrender will be the commuted

value of any unpaid annuity payments computed onthe basis of the assumed interest rate incorporated inthe annuity payments.

You must have a Medallion Signature Guarantee if youwant to surrender or withdraw a value of $500,000 ormore. Certain surrender requests of less than $500,000require either a Medallion Signature Guarantee, anotarized signature, or an attestation of your signatureby a Thrivent registered representative. Theseauthentication procedures are designed to protectagainst fraud. Such an authentication procedure may berequired for:

� Surrender of a value of $100,000 or more;

� Request to withdraw or surrender if there has beena change of address on the account within thepreceding 15 days; and

� Certain other transactions as determined by us.

A Medallion Signature Guarantee is a stamp provided bya financial institution that guarantees your signature.You sign the Thrivent Financial approved form andhave the signature(s) guaranteed by an eligibleguarantor institution such as a commercial bank, trustcompany, brokerage firm, credit union, or a savingsbank participating in the Medallion SignatureGuarantee Program. We may waive the MedallionSignature Guarantee in limited circumstances. A NotaryPublic is an individual who is authorized toauthenticate signatures and can be found in law firms ormany of the same places that an individual whoprovides Medallion Signature Guarantees can be found.Attestation by a financial representative requires theverification and witness of your signature by a ThriventFinancial representative. A partial surrender or surrendermay result in adverse tax consequences, including theimposition of a 10% federal premature distributionpenalty. For all surrenders, you should consider the taximplications of a surrender before you make a surrenderrequest. See Federal Tax Status.

Transfers

On or before the Annuity Commencement Date, youmay request the transfer of all or a part of yourContract’s Accumulated Value among the Subaccountsof the Variable Account and the Fixed Account.

You can request a transfer in two ways:

(1) By giving us Written Notice; or

(2) By telephone if we receive properauthorization from you.

We will make the transfer without charge at the end ofthe Valuation period during which we receive yourrequest. For transfers from the Fixed Account to aSubaccount of the Variable Account, the amount takenfrom the Fixed Account is used to buy AccumulationUnits of the chosen Subaccount. For transfers from aSubaccount, Accumulation Units of the Subaccount aresold and the resulting dollar amount is, depending onyour request, either transferred to the Fixed Account orused to buy Accumulation Units of another Subaccount.

Transfers are subject to the following conditions:

� The total amount transferred must be at least $200.However, if the total value in a Subaccount or theFixed Account is less than $200, the entire amountmay be transferred.

� We reserve the right to limit the number oftransfers in each Contract Year. However, we willalways allow at least 12 transfers per Contract Year.We consider all amounts transferred in the sameValuation Period to be one transfer. It is notdependent upon the number of originating ordestination Subaccounts.

� In any Contract Year, only one of your allowedtransfers may be from the Fixed Account. Anytransfer from the Fixed Account must be made onor within 45 days after a Contract Anniversarybefore the end of the valuation day.

Transfers will also be subject to any conditions that maybe imposed by the Portfolio whose shares are involved.

After the Annuity Commencement Date, you maychange the percentage allocation of variable annuitypayments among the available Subaccounts;

(1) By giving us Written Notice; or

(2) By telephone if we receive properauthorization from you.

Frequent Trading Policies

Because short-term or frequent transfers, purchases andredemptions of Contract value among Subaccounts poserisks to Contract Owners, we place limits on frequenttrading practices. Such risks include potentiallyimpaired investment performance due to disruption ofportfolio management strategies, increased transactionscosts, and dilution of fund shares (and therefore unitvalues) thereby negatively impacting the performance ofthe corresponding Subaccount.

We have policies and procedures to discourage frequenttransfers of value among Subaccounts. We usereasonable efforts to apply the policies and proceduresuniformly. Several different tactics are used to detectand prevent excessive trading within the Subaccounts.

As described in this section, we impose a fee if thetransfers made within a given time period exceed amaximum contractual number.

We also use a combination of monitoring ContractOwner activity and further restricting certain ContractOwner transfers based on a history of frequent transfersamong Subaccounts. When monitoring Contract Owneractivity, we may consider several factors to evaluatetransfer activity including, but not limited to, theamount and frequency of transfers, the amount of timebetween transfers and trading patterns. In making thisevaluation, we may consider trading in multipleContracts under common ownership or control.

Exceptions may apply to Dollar Cost Averaging,automatic investment plans, systematic withdrawalplans or non-abusive re-balancing. We reserve the right,in our sole discretion, to identify other trading practicesas abusive.

If we determine that you are engaging in excessivetrading activity, we will request that you cease suchactivity immediately. If we determine that you arecontinuing to engage in excessive trading, we willrestrict your Contract so that you can make transfers ononly one business day each calendar month and anysuch transfers must be separated by at least 20 calendardays. We reserve the right to reject or restrict anytransfer request, without notice for any reason.

In addition, the underlying Portfolios may have adoptedrestrictions designed to discourage frequent tradingpractices, and we reserve the right to enforce thesepolicies and procedures.

Although we seek to deter and prevent frequent tradingpractices, there are no guarantees that all activity can bedetected or prevented. Contract Owners engaging insuch trading practices use an evolving variety ofstrategies to avoid detection and it may not be possiblefor operational and technological systems to reasonablyidentify all frequent trading activity. Contract Ownersstill may be subject to their harmful effects if ThriventFinancial is unable to detect and deter abusive tradingpractices.

Dollar Cost Averaging

You may establish a dollar cost averaging program tomake periodic transfers of at least the minimum amountrequired from the Thrivent Money Market Subaccountto the other Subaccounts except the Fixed Account. Ifthe remaining amount to be transferred drops below theamount you established, the entire remaining balancewill be transferred on the next transfer date and thedollar cost averaging program will terminate. Transferswill be made automatically on the date you choose(except the 29th, 30th, or 31st of a month). Transferswill continue until the entire amount in the ThriventMoney Market Subaccount has been depleted or untilyou notify us to discontinue the program. In order tobegin, terminate or resume the program, we mustreceive Written Notice or notice by telephone (if youhave such authorization).

Asset Rebalancing

On or before the Annuity Date, you may participate inan optional asset rebalancing program that allows youto elect a specific asset allocation to maintain over time.The sum of the rebalancing percentages must be 100%and each rebalancing allocation percentage must be awhole number not greater than 100%. You may selectany date (except the 29th, 30th, or 31st of a month) tobegin the asset rebalancing program and whether tohave your Subaccounts reallocated semiannually orannually. The rebalancing will be done after all othertransfers and allocations to or from the Subaccounts forthe Valuation Day. The asset rebalancing program doesnot allow you to include the Fixed Account in therebalancing program. To participate in the assetrebalancing program, complete the Asset RebalancingForm at the time of your application or call1-800-847-4836 to request an Asset Rebalancing Form.The program will not terminate automatically bytransferring your allocations to another subaccount.

Telephone and Online Transactions

You may perform certain transactions online or over thetelephone if we receive proper authorization from you.

We have adopted reasonable security procedures toensure the authenticity of instructions, includingrequiring identifying information, recording telephoneconversations and providing written confirmations oftransactions. Nevertheless, we honor telephoneinstructions from any person who provides the correctidentifying information. Be aware that there is a risk ofpossible loss to the Owner if an unauthorized personuses this service in the Owner’s name.

Assignments

Assignment is the transfer of Contract ownership fromone party to another. If a Contract is used in a QualifiedPlan and the Contract Owner is a trust, custodian oremployer, then the Contract Owner may transfer

ownership to the Annuitant. Otherwise, the Contractmay not be sold, assigned, discounted or pledged ascollateral for a loan or as security for performance of anobligation or for any other purpose to any person otherthan us.

If the Contract is not used in a Qualified Plan, thenownership may be transferred, but not to a naturalperson, and the Contract may be assigned as collateral.

We must receive and approve any assignment requestbefore it is effective. We are not responsible for thevalidity or effect of any assignment.

You should consider the tax implications of anassignment. See Federal Tax Status.

Contract Owner, Beneficiaries and Annuitants

Unless another owner is named in the application, theAnnuitant is the owner of the Contract and mayexercise all of the owner’s rights under the Contract.

The Contract Owner may name a beneficiary to receivethe death benefit payable under the Contract. If thebeneficiary is not living on the date payment is due or ifno beneficiary has been named, the death benefit willbe paid to the estate of the Annuitant.

No Beneficiary change shall take effect unless receivedby the Society at its principal office or corporateheadquarters. When it is received, any change shall takeeffect as of the date the request for beneficiary changewas signed, as long as the request for change was mailedor actually delivered to the Society while the insuredwas alive. Such beneficiary change shall be null andvoid where the Society has made a good faith paymentof the proceeds or has taken other action beforereceiving the change.

CHARGES AND DEDUCTIONS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

Surrender Charge (Contingent Deferred SalesCharge)

We do not deduct a charge for sales expenses frompremiums at the time premiums are paid. Instead, wededuct a charge at the time you surrender all or part ofyour Accumulated Value. This surrender charge appliesonly during the first six Contract Years. During thoseyears, we calculate the surrender charge as a percentageof the amount which you surrender, subject to certainexceptions noted below.

Surrender Charges

Contract Year Percent Applied

1 6%2 5%3 4%4 3%5 2%6 1%

After Contract Year six there is no charge for makingsurrenders. In addition, during the first six ContractYears we will limit or waive surrender charges as follows:

� Cumulative Percent-of-Premium Limit. Forall surrenders, we will limit the surrender charge sothat on any date, the sum of all surrender chargesapplied to that date will not exceed 6.5% of thetotal of premiums you have paid to that date.

� Surrenders Paid Under Certain SettlementOptions. For surrenders which you make afterContract Year three, there is no surrender chargeapplied to amounts which you elect to have paidunder:

(1) A settlement option for a fixed amount or afixed period (including Option 3V describedunder Annuity Provisions—Settlement Options) ifthe payment period and the accumulationperiod will equal or exceed the surrender chargeperiod and you agree at the time of settlementthat after the first payment is made, you maynot revoke or change the settlement option.

(2) Options which involve a life income,including Option 4V or 5V described underAnnuity Provisions—Settlement Options.

� Ten Percent Free Each Contract Year. In eachContract Year, you may surrender without asurrender charge up to 10% of the AccumulatedValue existing at the time of your first surrendermade in that Contract Year. This “Ten Percent Free”is not cumulative. For example, if you make nosurrenders during the first three Contract Years, thepercentage of Accumulated Value which you maysurrender without charge in the fourth ContractYear is 10%, not 40%.

� Total Disability of the Annuitant. There is nosurrender charge if the Annuitant is totally disabled(as defined in your Contract) on the date of asurrender.

� Series of Substantially Equal PeriodicPayments for Life. There is no surrender chargeif you receive payments made as one of a series ofsubstantially equal periodic payments for your lifeor your life expectancy or the joint lifeexpectancies of you and your beneficiary made notless frequently than annually.

Certain surrenders are subject to a 10% Federal taxpenalty on the amount of income withdrawn. SeeFederal Tax Status.

If surrender charges are not sufficient to cover our salesexpenses, we will bear the loss; conversely, if theamount of such charges proves more than enough, wewill retain the excess. See Sufficiency of Charges below.We do not currently believe that the surrender chargeswe impose will cover our expected costs of distributingthe Contracts.

Administrative Charge

Your Contract includes an annual administrative chargeof $30 to help us cover the expenses we incur inadministrating your Contract, the Variable Account andthe Subaccounts. On each Contract Anniversary prior toand including the Annuity Commencement Date, wewill determine if this charge will be applied to yourContract. We apply the charge only on ContractAnniversaries on which the sum of premiums you havepaid less the amount of any partial surrenders you havemade is less than $5,000 and the Accumulated Value isless than $5,000. We deduct the charge from yourAccumulated Value, allocating the deduction among the

Subaccounts and the Fixed Account so that all accountsare reduced in value by the same percentage. Any suchdeduction from a Subaccount is made by sellingAccumulation Units of the Subaccount. With ourapproval, you may specify a different allocation for theadministrative charge.

Mortality and Expense Risk Charge

We assume certain financial risks associated with theContracts. Those risks are of two basic types:

� Mortality Risk. This includes our risk that (1)death benefits paid before the AnnuityCommencement Date will be greater than theAccumulated Value available to pay those benefits,and (2) Annuitant payments involving life incomeswill continue longer than we expected due to lowerthan expected death rates of the persons receivingthem.

� Expense Risk. This is the risk that the expenses,with respect to the Contracts, will exceed Contractcharges.

As compensation for assuming these risks, we deduct adaily mortality and expense risk charge from theaverage daily net assets in the Variable Account. Thecurrent charge (0.003014% per day) is equal to anannual rate of 1.10% of the average daily net assets ofeach Subaccount in the Variable Account during theaccumulation period. Contracts pending payout due toa death claim are charged at an annual rate of 0.95%.We may change this charge in the future, but weguarantee that it will never exceed an annual rate of1.25% (0.003425% per day).

If the mortality and expense risk charge is insufficient tocover the actual cost of the mortality and expense riskassumed by us, we will bear the loss. We will not reduceannuity payments or increase the administrative chargeto compensate for the insufficiency. If the mortality andexpense risk charge proves more than sufficient, theexcess will be profit available to us for any appropriatecorporate purpose including, among other things,payment of sales expenses. See Sufficiency of Chargesbelow.

Notwithstanding this charge, contract owners may beasked to add money under the Maintenance of Solvencyprovision described in General Provisions – Maintenance ofSolvency section.

Expenses of the Fund

Because the Variable Account purchases shares of theFund, the net assets of the Variable Account will reflectthe investment advisory fees or other expenses incurredby the Fund. See Fee and Expense Tables and theaccompanying current prospectus of the Fund.

Taxes

Currently, no charge will be made against the VariableAccount for Federal income taxes. We may, however,make such a charge in the future if income or gainswithin the Variable Account will result in any Federalincome tax liability to us. Charges for other taxes, ifany, attributable to the Variable Account may also bemade. See Federal Tax Status.

Sufficiency of Charges

If the amount of all charges assessed in connection withthe Contracts as described above is not enough to coverall expenses incurred in connection therewith, we willbear the loss. Any such expenses borne by us will bepaid out of our general account which may include,among other things, proceeds derived from mortalityand expense risk charges deducted from the VariableAccount. Conversely, if the amount of such chargesproves more than enough, we will retain the excess.

If our reserves become impaired, Contract Owners maybe asked to add money under the Maintenance ofSolvency provision described in General Provisions–Maintenance of Solvency section.

ANNUITY PROVISIONS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

Annuity Commencement Date

The Annuity Commencement Date is the date on whichwe begin paying you your Contract’s annuity income.This date is based on the maturity age which you specifyin your application. You may change the AnnuityCommencement Date by giving us notice in writing orby telephone before both the Annuity CommencementDate currently in effect and the new AnnuityCommencement Date. The new date selected mustsatisfy our requirements for an AnnuityCommencement Date and any requirements that maybe imposed by the state in which your Contract wasissued. At the Annuity Commencement Date stated inyour Contract, we may, at our discretion, allow you toextend the Annuity Commencement Date.

Your Contract provides for a death benefit if theAnnuitant dies before the Annuity CommencementDate. After the Annuity Commencement Date, amountspayable, if any, depend upon the terms of thesettlement option

Annuity Proceeds

The proceeds available on the Annuity CommencementDate will be the amount provided by surrendering yourContract’s Accumulated Value on that date. If theAnnuity Commencement Date occurs within the firstsix Contract Years, surrender charges will be deductedfrom the Accumulated Value if they apply.

We will pay you the proceeds at maturity according tothe annuity settlement option which you select.However, we will pay the proceeds in a single sum if theAccumulated Value on the Annuity CommencementDate is less than $2,000 or if you elect to receive theproceeds in a single sum. If we pay you proceeds in asingle sum, your Contract will terminate on the AnnuityCommencement Date.

If you have not selected either a settlement option or asingle sum payment by the Annuity CommencementDate, we will pay proceeds of $2,000 or more using afixed settlement option, life income with 10-yearguarantee period.

Settlement Options

You may elect to have proceeds paid to you under anannuity settlement option or a combination of options.Under each option, you may choose whether annuitypayments are to be made on a fixed or variable basis.You may change your choice of settlement option bygiving us Written Notice at least 30 days before theAnnuity Commencement Date.

The fixed annuity settlement options available to youare described in your Contract but are not summarizedhere. The variable annuity settlement options whichyour Contract offers are as follows:

� Option 3V—Income for a Fixed Period. Underthis option, we pay an annuity income for a fixednumber of years, not to exceed 30.

� Option 4V—Life Income with GuaranteedPeriod. Under this option, we pay an annuityincome for the lifetime of the payee. If the payeedies during the guaranteed period, payments willbe continued to the end of that period and will bepaid to the beneficiary. You may select a guaranteedperiod of 10 or 20 years

� Option 5V—Joint and Survivor Life Incomewith Guaranteed Period. Under this option, wepay an annuity income for as long as at least one oftwo payees is alive. If both payees die during theguaranteed period, payments will be continued tothe end of that period and will be paid to thebeneficiary. You may select a guaranteed period of10 or 20 years.

In addition to these options, proceeds may be paidunder any other settlement option agreeable to us.

Partial Annuitization

Federal tax law permits taxpayers to annuitize a portionof their annuity while leaving the remaining balance taxdeferred. You may elect to have a portion of yourproceeds ($2,000 or more) paid to you under an annuitysettlement option or a combination of options. Thesettlement option(s) must be for a fixed amount or fixedperiod payable for at least ten years, or a single or jointlife income with or without a guaranteed period, or anyother option agreeable to us. If this requirement is met,the settlement option and the tax-deferred balance will

generally be treated as two separate contracts for incometax purposes only. Your after-tax premiums in yourcontract will be allocated pro-rata between thesettlement option and the portion that remainsdeferred.

Frequency of Annuity Payments

Annuity payments under a settlement option will bepaid at monthly intervals unless you and we agree to adifferent payment schedule. If annuity payments wouldbe or become less than $25 ($20 for Contracts issued inthe state of Texas) if a single settlement option ischosen, or $25 ($20 for Contracts issued in the state ofTexas) on each basis if a combination of variable andfixed options is chosen, we may change the frequencyof payments to intervals that will result in payments ofat least $25 ($20 for Contracts issued in the state ofTexas) each from each option chosen.

Amount of Variable Annuity Payments

The amount of the first variable annuity payment isdetermined by applying the proceeds to be paid under aparticular settlement option to the annuity table in theContract for that option. The table shows the amount ofthe initial annuity payment for each $1,000 applied.

Subsequent variable annuity payments vary in amountaccording to the investment experience of the selectedSubaccount(s). Assuming annuity payments are basedon the unit values of a single Subaccount, the dollaramount of the first annuity payment (as determinedabove) is divided by the Annuity Unit Value as of theAnnuity Commencement Date to establish the numberof Annuity Units representing each annuity payment.This number of Annuity Units remains fixed during theannuity payment period. The dollar amount of thesecond and subsequent variable annuity payments isnot predetermined and may change from payment topayment. The dollar amount of the second and eachsubsequent variable annuity payment is determined bymultiplying the fixed number of Annuity Units by theAnnuity Unit Value. See Subaccount Annuity Unit Value

below. If the payment is based upon the Annuity UnitValues of more than one Subaccount, the proceduredescribed here is repeated for each applicableSubaccount and the sum of the payments based on eachSubaccount is the amount of the annuity payment.

The annuity tables in the Contracts are based on themortality table specified in the Contract. Under thesetables, the longer the life expectancy of the Annuitantunder any life annuity option or the duration of anyperiod for which payments are guaranteed under theoption, the smaller will be the amount of the firstmonthly variable annuity payment. We guarantee thatthe dollar amount of each fixed and variable annuitypayment after the first payment will not be affected byvariations in expenses or in mortality experience fromthe mortality assumptions used to determine the firstpayment.

Subaccount Annuity Unit Value

A Subaccount’s Annuity Unit Value is used to determinethe dollar value of annuity payments based on AnnuityUnits of the Subaccount. Annuity Unit Values mayincrease or decrease during each Valuation Period. Were-determine the Annuity Unit Value for eachSubaccount at the end of each Valuation Period. Theinitial Annuity Unit Value for a Subaccount was equal tothe initial Accumulation Unit Value for thatSubaccount. At the end of any subsequent ValuationPeriod, each Subaccount’s Annuity Unit Value is equalto (a) x (b) x (c) where:

(a) Is that Subaccount’s Annuity Unit Value at theend of the immediately preceding ValuationPeriod.

(b) Is that Subaccount’s Net Investment Factor forthe current Valuation Period. See The Contract—Subaccount Valuation—Net Investment Factordescribed earlier in this Prospectus.

(c) Is a discount factor equivalent to an assumedinvestment earnings rate of 3.5% per year oranother percentage agreed to by us.

In 1983, the U.S. Supreme Court held in ArizonaGoverning Committee v. Norris that the application ofsex-distinct actuarial tables to employees based upontheir gender in calculating the amount of retirementbenefits violates Title VII of the Civil Rights Act of 1963.Because of this decision, employer-sponsored retirementplans may not use sex-distinct actuarial annuity rates indetermining benefits.

Generally, annuity payments described in thisProspectus are determined using sex-distinct actuarialtables based on the Annuitant’s gender. However,annuity payments will be based on a gender neutralbasis for the following:

� Contracts used in an employer sponsoredretirement plan;

FEDERAL TAX STATUS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

General

The following discussion of the federal income taxtreatment of the Contract is not exhaustive, does notpurport to cover all situations, and is not intended astax advice. The federal income tax treatment of theContract is unclear in certain circumstances, and aqualified tax advisor should always be consulted withregard to the application of law to individualcircumstances. This discussion is based on the InternalRevenue Code of 1986, as amended (the “Code”),Treasury Department regulations, and interpretationsexisting on the date of this Prospectus. Theseauthorities, however, are subject to change by Congress,the Treasury Department, and judicial decisions.

This discussion does not address any federal estate orgift tax consequences, or any state or local taxconsequences, associated with the Contract. In addition,we make no guarantee regarding any tax treatment—federal, state, or local—of any Contract or anytransaction involving a Contract.

Tax Status of the Variable Account

The Variable Account is not separately taxed as a“regulated investment company” under the Code, butrather is treated as our separate account. Under currentlaw, both the investment income and realized capitalgains of the Variable Account (i.e., the income andcapital gains distributed to the Variable Account by theFund) are reinvested without taxation to us. However,we reserve the right in the future to make a chargeagainst the Variable Account or the Accumulated Valueof a Contract for any federal, state, or local income taxesthat we incur and determine to be attributable to theVariable Account or the Contract.

Taxation of Annuities in General

The following discussion assumes that the Contract isnot used in connection with a Qualified Plan.

Tax Deferral During Accumulation Period

In general, under current law, an increase in a Contract’sAccumulated Value is not taxable to the ContractOwner until received, either in the form of annuityincome payments as contemplated by the Contract orin some other form of distribution. However, this ruleapplies only if: (1) the investments of the VariableAccount are “adequately diversified” in accordance withTreasury Department regulations; (2) the Company,rather than the Contract Owner, is considered theowner of the assets of the Variable Account for federalincome tax purposes; (3) the Contract Owner is anindividual (or an individual is treated as the ContractOwner for tax purposes); and (4) the Contract’s AnnuityDate is not unduly delayed.

Diversification Requirements. The Code andTreasury Department regulations prescribe the mannerin which the investments of a segregated asset account,such as the Variable Account, are to be “adequatelydiversified.” If the Variable Account fails to comply withthese rules, the Contract will not be treated as anannuity Contract for federal income tax purposes, andso the interest or earnings credited to the Contract’sAccumulated Value in any year will be includible in theContract Owner’s income that year for federal taxpurposes. We expect that the Variable Account, throughthe Fund, will comply with these rules.

Ownership Treatment. In certain circumstances,variable annuity Contract Owners may be consideredthe owners, for federal income tax purposes, of theassets of a segregated asset account used to support theirContracts. In those circumstances, the account’s incomeand gains would be currently includible in the ContractOwners’ gross income. The Internal Revenue Service(the “IRS”) has stated in published rulings that avariable Contract Owner will be considered the ownerof the assets of a segregated asset account if the ownerpossesses incidents of ownership in those assets, such asthe ability to exercise investment control over theassets.

The ownership rights under the Contract are similar to,but different in certain respects from, the ownershiprights described in IRS rulings in which the ContractOwners were determined not to be the owners of theassets of a segregated asset account. For example, the

Contract Owner has the choice of more investmentoptions to which to allocate premium payments and theAccumulated Value than were addressed in thoserulings. These differences could result in the ContractOwner being treated as the owner of all or a portion ofthe assets of the Variable Account and thus subject tocurrent taxation on the income and gains from thoseassets. In addition, we do not know what standards willbe set forth in any further regulations or rulings whichthe Treasury Department or the IRS may issue. Wetherefore reserve the right to modify the Contract asnecessary to attempt to prevent Contract Owners frombeing considered the owners of the assets of the VariableAccount. However, there is no assurance that suchefforts would be successful.

Contracts Not Owned by Individuals. As a generalrule, Contracts held by “nonnatural persons” such as acorporation, trust, or other similar entity are not treatedas annuity Contracts for federal tax purposes. Theincome on such Contracts (as defined in the tax law) istaxed as ordinary income that is received or accrued bythe Contract Owner during the taxable year. However,this rule generally will not apply to a Contract held by atrust or other entity which holds the Contract as anagent for a natural person. In addition, this rule will notapply to: (1) a Contract acquired by the estate of adecedent by reason of the death of the decedent; (2)Contracts used in connection with certain QualifiedPlans; (3) Contracts purchased by employers upon thetermination of certain Qualified Plans; (4) certainContracts used in connection with structured settlementagreements; and (5) a Contract purchased with a singlepremium payment when the annuity starting date is nolater than one year from the purchase of the Contractand substantially equal periodic payments are made,not less frequently than annually, during the annuityincome period.

The remainder of this discussion assumes that theContract will be treated as an annuity Contract forfederal income tax purposes.

Taxation of Partial and Full Surrenders

In the case of a partial surrender, the amount received isgenerally includible in income for federal tax purposesto the extent that the Accumulated Value of theContract, before the partial surrender, exceeds the

“investment in the Contract.” In the case of a fullsurrender, the amount received is includible in incometo the extent that it exceeds the investment in theContract. For these purposes, the investment in theContract at any time equals the total of the premiumpayments made under the Contract up to that time lessany amounts previously received from the Contractwhich were excludable from income. All amountsincludible in income with respect to the Contract aretaxed as ordinary income; no amounts are taxed at thelower rates currently applicable to long-term capitalgains and corporate dividends.

Taxation of Annuity Income Payments

Normally, the portion of each annuity income paymentincludible in income for federal tax purposes is theexcess of the payment over an exclusion amount. In thecase of variable income payments, this exclusionamount is the investment in the Contract (definedabove) allocated to the Variable Account whenpayments begin, adjusted for any period certain orrefund feature, divided by the number of paymentsexpected. In the case of fixed income payments, theexclusion amount is determined by multiplying (1) thepayment, by (2) the ratio of the investment in theContract allocated to our Fixed Account, adjusted forany period certain or refund feature, to the totalexpected amount of annuity income payments. For thispurpose, the expected number or amount of annuityincome payments is determined by TreasuryDepartment regulations which take into account theAnnuitant’s life expectancy and the form of annuitybenefit selected.

Once the total amount of the investment in theContract is excluded using the above formulas, annuityincome payments will be fully taxable. If annuityincome payments cease because of the death of theAnnuitant and before the total amount of theinvestment in the Contract is recovered, theunrecovered amount generally will be allowed as adeduction.

Income from annuities will be subject to the MedicareTax on Investment Income. This tax will be imposed onindividuals with a modified adjusted gross income(MAGI) of more than $200,000 and joint filers with an

MAGI of more than $250,000. Generally, the tax ratewill be 3.8% of the lesser of the net investment incomeor the amount the MAGI exceeds the threshold amount.

There may be special income tax issues present insituations where the Contract Owner and the Annuitantare not the same person and are not married to oneanother. In such situations a tax advisor should beconsulted.

Tax Treatment of Death Benefit

Prior to the Annuity Date, we may distribute amountsfrom a Contract because of the death of a ContractOwner or, in certain circumstances, the death of theAnnuitant. If distributed in a lump sum, such deathbenefit proceeds are includible in income in the samemanner as a full surrender, or if distributed under anannuity income option, such proceeds are includible inthe same manner as annuity income payments.

After the Annuity Date, where a guaranteed periodexists under a life income option and the Annuitantdies before the end of that period, payments made tothe beneficiary for the remainder of that period areincludible in income as follows: (1) if received in a lumpsum, the payment is includible to the extent that itexceeds the unrecovered investment in the Contract; or(2) if distributed in accordance with the existingannuity income option, they are fully excluded fromincome until the remaining investment in the Contractis deemed to be recovered, and all payments thereafterare fully includible in income.

Assignments, Pledges, and Gratuitous Transfers

Any assignment or pledge of (or agreement to assign orpledge) any portion of the Accumulated Value of theContract is treated for federal income tax purposes as asurrender of such amount or portion. The investment inthe Contract is increased by the amount includible inincome with respect to such an assignment or pledge. Ifa Contract Owner transfers a Contract without adequateconsideration to a person other than the Owner’sSpouse (or a former Spouse incident to divorce), theOwner must include in income the difference betweenthe Contract’s Accumulated Value and the investmentin the Contract at the time of the transfer.

case, the transferee’s investment in the Contract isincreased to reflect the amount includible in thetransferor’s income.

Penalty Tax on Premature Distributions

Technically, the amount of any payment from theContract that is includible in income is subject to a 10%penalty tax. However, this penalty tax does not apply toany payment: (1) received on or after the ContractOwner attains age 591⁄2; (2) attributable to the ContractOwner’s becoming disabled (as defined in the tax law);(3) made on or after the death of the Contract Owneror, if the Contract Owner is not an individual, on orafter the death of the primary annuitant (as defined inthe tax law); (4) that is part of a series of substantiallyequal periodic payments, not less frequently thanannually, for the life or life expectancy of the ContractOwner or the joint lives or joint life expectancies of theContract Owner and a designated beneficiary (asdefined in the tax law). For the purposes of substantiallyequal periodic payments, if there is a significantmodification of the payment schedule before the laterof the taxpayer reaching age 591⁄2 or the expiration offive years from the time the payment starts, thetaxpayer’s income shall be increased by the amount oftax and deferred interest that otherwise would havebeen incurred.

Aggregation of Contracts

In certain circumstances, the IRS may determine theamount of any distribution from the Contract that isincludible in income by combining some or all of theannuity contracts a person owns. For example, if aperson purchases a contract and also purchases atapproximately the same time another deferred annuityissued by us, the IRS may treat the two contracts as onecontract. Similarly, if a person transfers part of his or herinterest in one annuity contract to purchase anotherannuity contract, the IRS might treat the two contractsas one contract. In addition, if a person purchases twoor more contracts from us (or an affiliate) during anycalendar year, all such contracts will be treated as onecontract for purposes of determining the amount of anyfull or partial surrender that is includible in income. Theeffects of such aggregation are not always clear;however, such aggregation could affect the amount of a

surrender or an annuity payment that is taxable and theamount which might be subject to the 10% penalty taxdescribed above.

Exchanges of Annuity Contracts

We may issue the Contract in exchange for all or part ofanother annuity contract. Such an exchange will beincome tax free if certain requirements are satisfied (a1035 Exchange). If the exchange is tax free, theinvestment in the Contract immediately after theexchange will generally be the same as that of theannuity contract exchanged, increased by anyadditional premium payment made as part of theexchange. If part of an existing contract is exchangedfor the Contract, the IRS might treat the two contractsas one annuity contract in certain circumstances. (See“Aggregation of Contracts.”) You should consult your taxadvisor in connection with an exchange of all or part ofan annuity contract for the Contract.

Qualified Plans

The Contracts also are designed for use with severaltypes of Qualified Plans. When used in Qualified Plans,deferred annuities like the Contracts do not offeradditional tax-deferral benefits, but annuities offer otherproduct benefits to investors in Qualified Plans.Participants under such Qualified Plans as well asContract Owners, Annuitants, and beneficiaries arecautioned that the rights of any person to any benefitsunder such Qualified Plans may be subject to the termsand conditions of the plans themselves regardless of theterms and conditions of the Contracts issued inconnection with them. Those who intend to use theContract in connection with Qualified Plans shouldseek competent advice.

The tax rules applicable to Qualified Plans, and to aContract when used in connection with a QualifiedPlan, vary according to the type of plan and the termsand conditions of the plan itself, and they takeprecedence over the general annuity tax rules describedabove. For example, for full surrenders, partialsurrenders, and annuity income payments underContracts used in Qualified Plans, there may be no“investment in the contract,” with the result that thetotal amount received may be includible in income. Theincludible amount is taxed at ordinary income tax rates,

and a 10% penalty tax also may apply. Exceptions tothis penalty tax vary depending on the type of QualifiedPlan involved; in the case of an Individual RetirementAnnuity (discussed below), exceptions comparable tothose described above are available.

The following briefly describes certain types of QualifiedPlans in connection with which we may issue aContract.

Individual Retirement Accounts and Annuities.Section 408 of the Code permits eligible individuals tocontribute to an Individual Retirement Account or anIndividual Retirement Annuity (collectively known asan “IRA”). IRAs are subject to limits on the amountsthat may be contributed and deducted, on the personswho may be eligible to do so, and on the time whendistributions may commence. Also, subject to certainrequirements discussed below, you may “roll over”distributions from certain Qualified Plans on atax-deferred basis into an IRA.

Roth IRAs. Section 408A of the Code permits eligibleindividuals to contribute to a type of IRA known as a“Roth IRA.” Roth IRAs are generally subject to the samerules as non-Roth IRAs, but differ in several respects.Among the differences is that, although contributionsto a Roth IRA are not deductible, “qualifieddistributions” (those that satisfy certain waiting and userequirements) from a Roth IRA will be excludable fromincome. Subject to certain restrictions, a distributionfrom an eligible employer-sponsored qualified plan maybe directly moved to a Roth IRA. This movement iscalled a “qualified rollover contribution.”

Section 403(b) Plans. Section 403(b) of the Codepermits public school employees and employees ofcertain types of charitable, educational, and scientificorganizations to have their employers purchase annuityContracts for them and, subject to certain limitations,to exclude the amount of premium payments fromincome for federal tax purposes. Subject to planprovisions, distributions from a Contract purchasedunder section 403(b) may be paid only when theemployee reaches age 591⁄2, separates from service, dies,or becomes disabled, the 403(b) plan terminates, or inthe case of financial hardship. As a result, the ContractOwner will not be entitled to exercise the surrender

rights described under the heading “The Contracts—Surrender (Redemption)” unless one of the aboveconditions is satisfied. For contracts maintainedpursuant to an employer sponsored 403(b) plan, we mayrequire the employer’s signature to process any requestsfor withdrawal, surrender, rollover or transfers toanother contract.

Direct Rollovers

If your Contract is purchased under section 403(b) ofthe Code or is used in connection with certain otherQualified Plans, any “eligible rollover distribution” fromthe Contract will be subject to direct rollover andmandatory withholding requirements. An eligiblerollover distribution generally is any taxabledistribution from certain Qualified Plans (includingfrom a Contract purchased under section 403(b))excluding amounts such as minimum distributionsrequired under the Code. Under these requirements,federal income tax equal to 20% of the eligible rolloverdistribution will be withheld from the amount of thedistribution. Unlike withholding on certain otheramounts distributed from the Contract, discussed below,the Owner cannot elect out of withholding with respectto an eligible rollover distribution. However, this 20%withholding will not apply if the distribution is directlyrolled over to an IRA or to another eligible retirementplan.

Federal Income Tax Withholding

We will withhold and remit to the federal government apart of the taxable portion of each distribution madeunder a Contract unless the payee notifies us at orbefore the time of the distribution that he or she electsnot to have any amounts withheld. In certaincircumstances, we may be required to withhold tax. Thewithholding rates applicable to the taxable portion ofannuity income payments (other than eligible rolloverdistributions made in connection with Qualified Plans)are the same as the withholding rates generallyapplicable to payments of wages. Further, a 10%withholding rate applies to the taxable portion ofnon-periodic payments (including partial and fullsurrenders), and as discussed above, the withholdingrate applicable to eligible rollover distributions is 20%.Whether or not federal income tax is withheld, the

Thrivent Aggressive Allocation PortfolioInvestment ObjectiveThrivent Aggressive Allocation Portfolio (the �Portfolio�)seeks long-term capital growth.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.70%

Other Expenses 0.05%

Acquired Fund Fees and Expenses 0.22%

Total Annual Portfolio Operating Expenses 0.97%

Less Fee Waivers and/or ExpenseReimbursements1 0.21%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.76%

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2019, to waive anamount equal to any investment advisory fees indirectly incurredby the Portfolio as a result of its investment in any other mutualfund for which the Adviser or an affiliate serves as investmentadviser, other than Thrivent Cash Management Trust. Thiscontractual provision may be terminated upon the mutualagreement between the Independent Directors of the Portfolio andthe Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expense

reimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent AggressiveAllocation Portfolio $78 $288 $516 $1,171

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 63% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achievea desired risk tolerance generally aligned with its peergroup as published by Lipper, Inc. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,equity securities and debt securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes may be based on marketcapitalization, investment style (such as growth orvalue), or economic sector for equity securities.Sub-classes for debt securities may be based on maturity,duration, security type or credit rating (high yield—commonly known as “junk bonds”—or investmentgrade) and may include leveraged loans, which aresenior secured loans that are made by banks or otherlending institutions to companies that are rated belowinvestment grade.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments. The Portfoliomay also enter into credit default swap agreements on

security indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Under normal circumstances, the Portfolio invests inthe following broad asset classes within the rangesgiven:

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformance among asset categories. The Adviser willrebalance the Portfolio at least annually so that itsholdings are within the ranges for the broad assetcategories.

The Portfolio also pursues its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate. The names ofthe funds managed by the Adviser or an affiliate whichare currently available for investment by the Portfolioare shown in the list below.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets wouldhave a material adverse effect on the Portfolio’s totalreturn given its significant allocation to equitysecurities. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,

the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty. Common stock of a company issubordinate to other securities issued by the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smaller

companies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Adviser mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio invests. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. From time to time, equity investments mayfall out of favor as compared to investments in debtsecurities, and vice versa. Small, less seasonedcompanies and medium-size companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses.

deductions against your variable contract were included,returns would be lower than those shown.

The equity securities in which the Portfolio invests areprimarily income-producing and may include commonstock, preferred stock, securities convertible intocommon stock, or securities or other instruments theprice of which is linked to the value of common stock.Under normal circumstances, the Portfolio intends toinvest in real estate investment trusts (“REITs”).

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade. In addition, thePortfolio may invest in investment-grade corporatebonds, asset-backed securities, mortgage-backedsecurities (including commercially backed ones),convertible bonds, and sovereign and emerging marketdebt (both U.S. dollar and non-U.S. dollardenominated).

entities, and non-standardized derivatives contractstraded in the over-the-counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets ordebt markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to both equity securities and debt securities.Therefore, a principal risk of investing in the Portfolio isthat the allocation strategies used and the allocationdecisions made will not produce the desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may no

longer be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes in

exchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, which

typically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,

the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. In

addition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

Effective August 16, 2013, based on approval of thePortfolio’s Board of Directors and notice to Portfolioshareholders, the Portfolio’s principal strategies werechanged, which had the effect of converting thePortfolio from one which incorporated the strategies ofThrivent Large Cap Index Portfolio and Thrivent BondIndex Portfolio (now known as Thrivent GovernmentBond Portfolio) to one which invests in a combinationequity securities and debt securities. At the same time,the Portfolio’s name changed from Thrivent BalancedPortfolio to Thrivent Balanced Income Plus Portfolio.

entities, and non-standardized derivatives contractstraded in the over-the-counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. In particular, underperformance in the fixedincome markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to fixed income securities. Therefore, aprincipal risk of investing in the Portfolio is that theallocation strategies used and the allocation decisionsmade will not produce the desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may no

longer be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments.

Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes in

All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments.

In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,

the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. In

addition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. These indices arethe MSCI World Index—USD Net Returns, whichmeasures the performance of stock markets indeveloped countries throughout the world, theBloomberg Barclays U.S. Mortgage-Backed SecuritiesIndex, which covers the mortgage-backed securitiescomponent of the Bloomberg Barclays U.S. AggregateBond Index, the Bloomberg Barclays U.S. High YieldBa/B 2% Issuer Capped Index, which represents theperformance of high yield corporate bonds rated Ba orB, with a maximum allocation of 2% to any one issuer,and the S&P/LSTA Leveraged loan Index, which reflectsthe performance of the largest facilities in the leveragedloan market.

Call 800-847-4836 or visit Thrivent.com forperformance results current to the most recentmonth-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Thrivent Government Bond PortfolioInvestment ObjectiveThrivent Government Bond Portfolio (the �Portfolio�)seeks total return, consistent with preservation ofcapital. The Portfolio’s investment objective may bechanged without shareholder approval.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.35%

Other Expenses 0.10%

Total Annual Portfolio Operating Expenses 0.45%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent GovernmentBond Portfolio $46 $144 $252 $567

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 422% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount ofborrowings for investment purposes) in U.S.government bonds. For purposes of this disclosure, “U.S.government bonds” are debt instruments issued orguaranteed by the U.S. government or its agencies andinstrumentalities, including U.S. Treasuries, TreasuryInflation Protected Securities (TIPS), U.S. GovernmentAgency debt, and mortgage-backed securities issued orguaranteed by the Government National MortgageAssociation (GNMA or Ginnie Mae), the FederalNational Mortgage Association (FNMA or Fannie Mae)or the Federal Home Loan Mortgage Corporation(FHLMC or Freddie Mac). Should the Adviser determinethat the Portfolio would benefit from reducing thepercentage of its net assets invested in U.S. governmentbonds from 80% to a lesser amount, it will notify you atleast 60 days prior to the change.

The Portfolio’s portfolio securities may be of anymaturity. The Adviser uses fundamental, quantitativeand technical investment research techniques todetermine what debt obligations to buy and sell.Fundamental techniques assess a security’s value basedon an issuer’s financial profile, management, andbusiness prospects while quantitative and technicaltechniques involve a more data-oriented analysis offinancial information, market trends and pricemovements. The “total return” sought by the Portfolioconsists of income earned on the Portfolio’s investmentsplus, if any, capital appreciation. The Portfolio mayinvest in U.S. dollar denominated sovereign debt offoreign governments. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similar

entities, and non-standardized derivatives contractstraded in the over-the-counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as GinnieMae, Fannie Mae or Freddie Mac securities). Securitiesissued or guaranteed by Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Fannie Maeand Freddie Mac are not backed by the full faith andcredit of the U.S. government. No assurance can begiven that the U.S. government would provide financialsupport to its agencies and instrumentalities if notrequired to do so by law. In addition, the value of U.S.government securities may be affected by changes in thecredit rating of the U.S. government.

Inflation-Linked Security Risk. Inflation-linked debtsecurities, such as TIPS, are subject to the effects ofchanges in market interest rates caused by factors otherthan inflation (real interest rates). In general, the priceof an inflation-linked security tends to decrease whenreal interest rates increase and can increase when realinterest rates decrease. Interest payments oninflation-linked securities are unpredictable and willfluctuate as the principal and interest are adjusted forinflation. Any increase in the principal amount of aninflation-linked debt security will be considered taxable

ordinary income, even though the Portfolio will notreceive the principal until maturity.

There can also be no assurance that the inflation indexused will accurately measure the real rate of inflation inthe prices of goods and services. The Portfolio’sinvestments in inflation-linked securities may lose valuein the event that the actual rate of inflation is differentthan the rate of the inflation index. In addition,inflation-linked securities are subject to the risk that theConsumer Price Index for All Urban Consumers (CPI-U)or other relevant pricing index may be discontinued,fundamentally altered in a manner materially adverse tothe interests of an investor in the securities, altered bylegislation or Executive Order in a materially adversemanner to the interests of an investor in the securitiesor substituted with an alternative index.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Some municipal bonds may be repaidprior to maturity if interest rates decrease. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Inventories of bonds areat or near historic lows in relation to market size, whichhas the potential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a resultof this decreased liquidity, the Adviser may have toaccept a lower price to sell a security, sell other securitiesto raise cash, or give up an investment opportunity, anyof which could have a negative effect on performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Sovereign Debt Risk. The Portfolio may invest insovereign debt securities. These securities are issued orguaranteed by foreign governmental entities. Theseinvestments are subject to the risk that a governmentalentity may delay or refuse to pay interest or repayprincipal on its sovereign debt, due, for example, tocash flow problems, insufficient foreign currencyreserves, political considerations, the relative size of thegovernmental entity’s debt position in relation to theeconomy or the failure to put in place economicreforms required by the International Monetary Fund orother multilateral agencies. If a governmental entitydefaults, it may ask for more time in which to pay or forfurther loans. There is no legal process for collectingsovereign debts that a government does not pay nor arethere bankruptcy proceedings through which all or partof the sovereign debt that a governmental entity hasnot repaid may be collected.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to year

and by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indices areBloomberg Barclays U.S. Agency Index and theBloomberg Barclays U.S. Treasury Index. The BloombergBarclays U.S. Agency Index measures the performance ofthe agency sector of the U.S. government bond market.The Bloomberg Barclays U.S. Treasury Index measuresthe performance of the U.S. Treasury bond market. Call800-847-4836 or visit Thrivent.com for performanceresults current to the most recent month-end.

The Portfolio no longer uses the Bloomberg BarclaysU.S. Aggregate Bond Index because, effective August 28,2017, based on approval of the Portfolio’s Board ofDirectors and shareholders, the portfolio’s investmentobjective and principal strategies were changed, whichhad the effect of converting the Portfolio from onewhose securities were selected based on which securitieswere in an index to one that is actively managed andinvests primarily in U.S. government securities. At thesame time, the Portfolio’s name changed from ThriventBond Index Portfolio to Thrivent Government BondPortfolio. As a result, performance informationpresented below with respect to periods prior toAugust 28, 2017, reflects the performance of aninvestment portfolio that was materially different fromthe investment portfolio of Thrivent Government BondPortfolio.

The bar chart and the table include the effects ofPortfolio expenses, but not charges or deductionsagainst your variable contract, and assume that you soldyour shares at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How the Portfolio has performed in the past (before andafter taxes) is not necessarily an indication of how it willperform in the future. Performance informationprovides some indication of the risks of investing in thePortfolio by showing changes in the Portfolio’sperformance over time.

1 The Adviser has contractually agreed, through at least April 30,2019, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent Growth and Income PlusPortfolio in order to limit the Total Annual Portfolio OperatingExpenses After Fee Waivers and/or Expense Reimbursements, if any,to an annual rate of 0.90% of the average daily net assets of the

shares. This contractual provision, however, may be terminatedbefore the indicated termination date upon the mutual agreementbetween the Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Growth andIncome Plus Portfolio $95 $309 $541 $1,208

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 131% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests in acombination of equity securities and debt securitieswithin the ranges shown in the following table:

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade. In addition, thePortfolio may invest in investment-grade corporatebonds, asset-backed securities, mortgage-backedsecurities (including commercially backed ones),convertible bonds, and sovereign and emerging marketdebt (both U.S. dollar and non-U.S. dollardenominated).

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. In particular, underperformance in the equitymarkets would have a material adverse effect on thePortfolios’ total return given their significant allocationto equity securities. Therefore, a principal risk ofinvesting in the Portfolio is that the allocation strategiesused and the allocation decisions made will not producethe desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countries

significantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in the

repayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase price

volatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferred

dividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-year and five-year periods and sinceinception compared to broad-based securities marketindices. These indices are the MSCI World Index—USDNet Returns, which measures the performance of stockmarkets in developed countries throughout the world,the Bloomberg Barclays U.S. Mortgage-Backed SecuritiesIndex, which covers the mortgage-backed securitiescomponent of the Bloomberg Barclays U.S. AggregateBond Index, Bloomberg Barclays U.S. High Yield Ba/B2% Issuer Capped Index, which represents theperformance of high yield corporate bonds rated Ba orB, with a maximum allocation of 2% to any one issuer,and the S&P/LSTA Leveraged Loan Index, which reflectsthe performance of the largest facilities in the leveragedloan market.

Effective August 16, 2013, based on approval of thePortfolio’s Board of Directors, the Portfolio’s investmentobjective and principal strategies were changed, whichhad the effect of converting the Portfolio from onewhich invested at least 80% of its assets inincome-producing equity securities to one which investsin a combination of equity securities and debt securities.At the same time, the Portfolio’s name changed fromThrivent Equity Income Plus Portfolio to ThriventGrowth and Income Plus Portfolio. As a result,performance information presented below with respectto periods prior to August 16, 2013, reflects theperformance of an investment portfolio that wasmaterially different from the investment portfolio ofThrivent Growth and Income Plus Portfolio.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assumes that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 50% ofthe average value of its portfolio.

Principal StrategiesUnder normal market conditions, the Portfolio investsat least 80% of its net assets (plus the amount of anyborrowing for investment purposes) in high yield, highrisk bonds, notes, debentures and other debt obligations(including leveraged loans, mortgage-backed securities,convertible bonds, and convertible stock), or preferredstocks. These securities are commonly known as “junkbonds.” At the time of purchase these securities arerated within or below the “BB” major rating category byStandard & Poor’s Corporation or the “Ba” major ratingcategory by Moody’s Investor Services, Inc. or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio invests in securities regardlessof the securities’ maturity average and may also investin foreign securities. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in junk bonds from 80% to a lesser amount, wewill notify you at least 60 days prior to the change.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques to determinewhat securities to buy and sell. Fundamental techniquesassess a security’s value based on an issuer’s financialprofile, management, and business prospects whilequantitative and technical techniques involve a moredata-oriented analysis of financial information, markettrends and price movements. The Adviser focuses onU.S. companies which it believes have or are expected toachieve adequate cash flows or access to capital marketsfor the payment of principal and interest obligations.

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objectives.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of the

security is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase price

volatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to year

and by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index. The index is theBloomberg Barclays U.S. Corporate High Yield BondIndex, which measures the performance of fixed-ratenon-investment grade bonds. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Thrivent Income PortfolioInvestment ObjectiveThrivent Income Portfolio (the �Portfolio�) seeks toachieve a high level of income over the longer termwhile providing reasonable safety of capital.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.40%

Other Expenses 0.04%

Total Annual Portfolio Operating Expenses 0.44%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent IncomePortfolio $45 $141 $246 $555

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 105% ofthe average value of its portfolio.

Principal StrategiesThe principal strategies of the Portfolio are to invest ininvestment-grade corporate bonds, government bonds,asset-backed securities, and mortgage-backed securities.(Asset-backed securities are securities backed by notes orreceivables originated by banks, credit card companiesor other providers of credit).

Under normal conditions, at least 65% of the Portfolio’sassets will be invested in debt securities or preferredstock that is rated investment grade (Baa3/BBB-/BBB- orhigher) using the middle rating of Moody’s, S&P andFitch; when a rating from only two agencies is available,the lower is used; when only one agency rates a bond,that rating is used. In cases where explicit bond levelratings may not be available, the Adviser may use othersources to classify securities by credit quality.

The Portfolio may also invest in high yield, high riskbonds, notes, debentures and other debt obligations orpreferred stock commonly known as “junk bonds.” Atthe time of purchase these securities are rated within orbelow the “BB” major rating category by S&P or the“Ba” major rating category by Moody’s or are unratedbut considered to be of comparable quality by theAdviser.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques to determinewhat debt obligations to buy and sell. Fundamentaltechniques assess a security’s value based on an issuer’sfinancial profile, management, and business prospectswhile quantitative and technical techniques involve amore data-oriented analysis of financial information,market trends and price movements. The Adviser maypurchase bonds of any maturity and generally focuseson U.S. companies that it believes are financially soundand have strong cash flow, asset values and interest ordividend earnings. The Adviser purchases bonds offoreign issuers as well. Additionally, the Portfolio mayinvest in leveraged loans, which are senior secured loansthat are made by banks or other lending institutions tocompanies that are rated below investment grade. Pleasenote that the Portfolio will likely use an interest rate

management technique that includes the purchase andsale of U.S. Treasury securities and related futurescontracts for the purpose of managing the duration ofthe Portfolio. The Portfolio may utilize other derivatives(such as swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market. The Portfoliomay also pursue its investment strategy by investing inother mutual funds, including funds managed by theAdviser or an affiliate.

The Portfolio may invest in securities of any marketsector and may hold a significant amount of securitiesof companies, from time to time, within a single sectorsuch as financials.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Financial Sector Risk. To the extent that thefinancials sector continues to represent a significantportion of the Portfolio, the Portfolio will be sensitive tochanges in, and its performance may depend to agreater extent on, factors impacting this sector.Performance of companies in the financials sector maybe adversely impacted by many factors, including,among others, government regulations, economicconditions, credit rating downgrades, changes in

interest rates, and decreased liquidity in credit markets.The impact of more stringent capital requirements,recent or future regulation of any individual financialcompany or recent or future regulation of the financialssector as a whole cannot be predicted. In recent years,cyber attacks and technology malfunctions and failureshave become increasingly frequent in this sector andhave caused significant losses.

Foreign Securities Risk. To the extent the Portfolio isexposed to foreign securities, it is subject to various risksassociated with such securities. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategy

depends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Inventories of bonds areat or near historic lows in relation to market size, whichhas the potential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a resultof this decreased liquidity, the Adviser may have toaccept a lower price to sell a security, sell other securitiesto raise cash, or give up an investment opportunity, anyof which could have a negative effect on performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlying

such securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Bonds may exhibit price fluctuations due tochanges in interest rates or bond yield levels.

1 Year 3 Years 5 Years 10 Years

Thrivent Large CapGrowth Portfolio $45 $141 $246 $555

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 59% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof large companies. The Adviser focuses mainly on theequity securities of large domestic and internationalcompanies which have market capitalizationsequivalent to those included in widely known indicessuch as the S&P 500 Index, the MSCI USA Large CapIndex, or the large company market capitalizationclassifications published by Lipper, Inc. Thesecompanies typically have a market capitalization ofapproximately $8 billion or more. Should the Adviserdetermine that the Portfolio would benefit fromreducing the percentage of its assets invested in equitysecurities of large cap companies from 80% to a lesseramount, we will notify you at least 60 days prior to thechange.

by investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projection offuture earnings or revenues and, if a company’s earningsor revenues fall short of expectations, its stock pricemay fall dramatically.

Thrivent Large Cap Index PortfolioInvestment ObjectiveThrivent Large Cap Index Portfolio (the �Portfolio�)seeks total returns that track the performance of the S&P500 Index.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.20%

Other Expenses 0.05%

Total Annual Portfolio Operating Expenses 0.25%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Large CapIndex Portfolio $26 $80 $141 $318

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 3% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in the large company commonstocks included in the S&P 500 Index in the proportionsin which they are represented in the index. This is apassively managed Portfolio, which means that theAdviser does not actively choose the securities thatshould make up the Portfolio. The S&P 500 Index iscomprised of 500 domestic large company stocks.Accordingly, the Portfolio invests in stocks of largercompanies from a broad range of industries. The S&P500 Index is adjusted quarterly, and when changes tothe index occur, the Adviser will attempt to replicatethese changes within the Portfolio. However, any suchchanges may result in slight variations from time totime. The Portfolio may buy and sell equity indexfutures for investment exposure. For liquidity reasons,the Portfolio may invest to some degree in moneymarket instruments. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposed

will affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof large companies.

These companies typicallyhave a market capitalization of approximately $8 billionor more. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in equity securities of large capcompanies from 80% to a lesser amount, we will notifyyou at least 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in domestic and internationalcommon stocks. The Portfolio may buy and sell futurescontracts to either hedge its exposure or obtainexposure to certain investments. The Portfolio may alsopursue its investment strategy by investing in othermutual funds, including funds managed by the Adviseror an affiliate. The Adviser uses fundamental,quantitative, and technical investment researchtechniques to determine what stocks to buy and sell.Fundamental techniques assess a security’s value basedon an issuer’s financial profile, management, andbusiness prospects while quantitative and technicaltechniques involve a more data-oriented analysis offinancial information, market trends and pricemovements. The Portfolio may sell securities for avariety of reasons, such as to secure gains, limit losses,or reposition assets into more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Large CapValue Portfolio $65 $205 $357 $798

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate may

indicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 18% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof large companies. The Adviser focuses mainly on theequity securities of large domestic and internationalcompanies which have market capitalizationsequivalent to those included in widely known indicessuch as the S&P 500 Index, the MSCI USA Large CapIndex, or the large company market capitalizationclassifications published by Lipper, Inc. Thesecompanies typically have a market capitalization ofapproximately $8 billion or more. The Portfolio mayalso pursue its investment strategy by investing in othermutual funds, including funds managed by the Adviseror an affiliate. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in equity securities of large capcompanies from 80% to a lesser amount, we will notifyyou at least 60 days prior to the change.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques and focuseson stocks of companies that it believes are undervaluedin relation to their long-term earnings power or assetvalue. These stocks typically, but not always, have belowaverage price-to-earnings and price-to-book value ratios.The Portfolio may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsinto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Foreign Securities Risk. To the extent the Portfolio isexposed to foreign securities, it is subject to various risksassociated with such securities. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,

the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of the Portfolio’s investmentstrategy depends significantly on the skills of theAdviser in assessing the potential of the investments inwhich the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Value style investing includes the risk thatstocks of undervalued companies may not rise asquickly as anticipated if the market doesn’t recognizetheir intrinsic value or if value stocks are out of favor.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared toa broad-based securities market index. The index is theS&P 500 Value Index, which measures the performanceof the value stocks in the S&P 500 Index. Call800-847-4836 or visit Thrivent.com for performanceresults current to the most recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 64% ofthe average value of its portfolio.

Principal StrategiesThe principal strategies of the Portfolio are to invest ininvestment-grade corporate bonds, government bonds,municipal bonds, mortgage-backed securities (includingcommercially backed ones), asset-backed securities, andcollateralized debt obligations (including collateralizedloan obligations). Asset-backed securities are securitiesbacked by notes or receivables originated by banks,credit card companies, or other providers of credit;collateralized debt obligations are types of asset-backedsecurities. Under normal market conditions, thePortfolio invests at least 80% of its net assets (plus theamount of any borrowing for investment purposes) indebt securities or preferred stock in at least the “Baa”major rating category by Moody’s or at least in the“BBB” major rating category by S&P or unratedsecurities considered to be of comparable quality by thePortfolio’s Adviser, with the dollar-weighted averageeffective maturity for the Portfolio expected to bebetween one and five years. Should the Adviserdetermine that the Portfolio would benefit fromreducing the percentage of its assets invested in suchinvestment grade securities from 80% to a lesseramount, we will notify you at least 60 days prior to thechange.

The Portfolio may also invest in high yield, high riskbonds, notes, debentures and other debt obligations orpreferred stock commonly known as “junk bonds.” Atthe time of purchase, these securities are rated within orbelow the “BB” major rating category by S&P or the“Ba” major rating category by Moody’s or are unratedbut considered to be of comparable quality by theAdviser.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques to determinewhat debt obligations to buy and sell. Fundamentaltechniques assess a security’s value based on an issuer’sfinancial profile, management, and business prospectswhile quantitative and technical techniques involve amore data-oriented analysis of financial information,market trends and price movements. The Adviser

focuses on companies that it believes are financiallysound and have strong cash flow, asset values andinterest or dividend earnings. Some of these companiesmay be foreign ones. Additionally, the Portfolio mayinvest in leveraged loans, which are senior secured loansthat are made by banks or other lending institutions tocompanies that are rated below investment grade. Pleasenote that the Portfolio will likely use an interest ratemanagement technique that includes the purchase andsale of U.S. Treasury securities and related futurescontracts for the purpose of managing the duration ofthe Portfolio. The Portfolio may utilize other derivatives(such as swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market. The Portfoliomay also pursue its investment strategy by investing inother mutual funds, including funds managed by theAdviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Collateralized Debt Obligations Risk. The risks ofan investment in a collateralized debt obligation(“CDO”) depend largely on the quality and type of thecollateral and the tranche of the CDO in which thePortfolio invests. In addition to the typical risksassociated with fixed income securities and asset-backedsecurities, CDOs carry additional risks including, butnot limited to: (i) the possibility that distributions fromcollateral securities will not be adequate to makeinterest or other payments; (ii) the risk that thecollateral may default, decline in value, and/or bedowngraded; (iii) the Portfolio may invest in tranches ofCDOs that are subordinate to other tranches; (iv) thestructure and complexity of the transaction and thelegal documents could lead to disputes among investorsregarding the characterization of proceeds; (v) theinvestment return achieved by the Portfolio could besignificantly different than those predicted by financialmodels; (vi) the lack of a readily available secondarymarket for CDOs; (vii) risk of forced “fire sale”liquidation due to technical defaults such as coveragetest failures; and (viii) the CDO’s manager may performpoorly.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Inventories of bonds areat or near historic lows in relation to market size, whichhas the potential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a resultof this decreased liquidity, the Adviser may have toaccept a lower price to sell a security, sell other securitiesto raise cash, or give up an investment opportunity, anyof which could have a negative effect on performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related and

asset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Bonds may exhibit price fluctuations due tochanges in interest rates or bond yield levels.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index.

1 Certain other expense categories have been adjusted to annualizeexpenses after the initial short year to reflect current fees.

2 The Adviser has contractually agreed, through at least April 30,2019, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent Low Volatility Portfolioin order to limit the Total Annual Portfolio Operating ExpensesAfter Fee Waivers and/or Expense Reimbursements, if any, to anannual rate of 0.80% of the average daily net assets of the shares.This contractual provision, however, may be terminated before theindicated termination date upon the mutual agreement betweenthe Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and then

redeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent LowVolatility EquityPortfolio $82 $732 $1,407 $3,215

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance.

From inception on April 28, 2017 through the mostrecent fiscal year, the Portfolio’s portfolio turnover ratewas 35% of the average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securities.The Portfolio’s investments are diversified globally. ThePortfolio may invest in securities denominated in U.S.dollars and the currencies of the foreign countries inwhich it may invest. The Portfolio typically has fullcurrency exposure to those markets in which it invests.The Portfolio may buy or sell equity index futures forinvestment exposure or hedging purposes. The Portfoliomay invest in securities of any market capitalization,including small- and mid-cap securities. The Portfoliomay also pursue its investment strategy by investing inother mutual funds, including funds managed by theAdviser or an affiliate.

In seeking to achieve the Portfolio’s investmentobjective, the Adviser employs investment managementtechniques to identify securities that exhibit lowvolatility returns. Volatility refers to the variation insecurity and market prices over time. Over a full marketcycle, the Portfolio seeks to produce returns similar tothe MSCI World Index but with less volatility. It isexpected that the Portfolio will generally underperformthe global equity markets during periods of strongmarket performance.

In buying and selling securities for the Portfolio, theAdviser uses an active strategy. This strategy consists of adisciplined approach that involves computer-aided,quantitative analysis of fundamental, technical andrisk-related factors. The Adviser’s factor model (amethod of analyzing and combining multiple datasources) systematically reviews thousands of stocks,using data such as historical earnings growth andexpected future growth, valuation, price momentum,and other quantitative factors to forecast returnpotential. Then, risk characteristics of potentialinvestments and covariation among securities areanalyzed along with the return forecasts in determiningthe Portfolio’s holdings to produce a portfolio withreduced volatility.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Volatility Risk. Although the Portfolio seeks lowervolatility than the global equity markets, its returns willexperience some volatility. Volatility risk is the risk thatcertain types of securities shift in and out of favordepending on market and economic conditions as wellas investor sentiment. The value of the Portfolio’s sharesmay be affected by weak equity markets. As a result, thevalue of the Portfolio’s shares may fluctuatesignificantly in the short term.

PerformanceNo performance information for the Portfolio isprovided because it does not yet have a full year ofperformance history. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

How the Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 30% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof mid-sized companies. The Adviser focuses mainly onthe equity securities of mid-sized U.S. companies whichhave market capitalizations equivalent to thoseincluded in widely known indices such as the S&PMidCap 400 Index, MSCI USA Mid Cap Index, or themid-sized company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of approximately $2 billionto $25 billion. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in mid cap equity securities from 80%to a lesser amount, we will notify you at least 60 daysprior to the change.

The Portfolio seeks to achieve its investment objectiveby investing in common stocks. The Adviser usesfundamental, quantitative, and technical investmentresearch techniques to determine what securities to buyand sell. Fundamental techniques assess a security’svalue based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements. The Adviser generally looks formid-sized companies that, in its opinion:

• have prospects for growth in their sales andearnings;

• are in an industry with a good economic outlook;• have high-quality management; and/or• have a strong financial position.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2019, to waive anamount equal to any investment advisory fees indirectly incurredby the Portfolio as a result of its investment in any other mutualfund for which the Adviser or an affiliate serves as investmentadviser, other than Thrivent Cash Management Trust.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects the

effect of the contractual fee waiver and/or expensereimbursement.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 155% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achievea desired risk tolerance generally aligned with its peergroup as published by Lipper, Inc. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,equity securities and debt securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes may be based on marketcapitalization, investment style (such as growth orvalue), or economic sector for equity securities.Sub-classes for debt securities may be based on maturity,duration, security type or credit rating (high yield—commonly known as “junk bonds”—or investmentgrade) and may include leveraged loans, which aresenior secured loans that are made by banks or otherlending institutions to companies that are rated belowinvestment grade.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments. The Portfolio

may also enter into credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets ordebt markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to both equity securities and debt securities.Therefore, a principal risk of investing in the Portfolio isthat the allocation strategies used and the allocationdecisions made will not produce the desired results.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,

TSF-77

Page 126: Flexible Premium Deferred Variable Annuity · PDF fileFlexible Premium Deferred Variable Annuity Issued by Lutheran Brotherhood between 2/3/1994 and 4/30/2003. Prospectuses April 30,

the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smaller

companies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Adviser mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio invests. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. From time to time, equity investments mayfall out of favor as compared to investments in debtsecurities, and vice versa. Small, less seasonedcompanies and medium-size companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. These indices arethe S&P 500 Index, which measures the performance of500 widely held, publicly traded stocks, the BloombergBarclays U.S. Aggregate Bond Index, which measures theperformance of U.S. investment grade bonds, and theMSCI All Country World Index ex-USA—USD NetReturns, which measures the performance of stockmarkets in developed and emerging markets countriesthroughout the world (excluding the U.S.). Call800-847-4836 or visit Thrivent.com for performanceresults current to the most recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets wouldhave a material adverse effect on the Portfolio’s totalreturn given its significant allocation to equitysecurities. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,

the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smaller

companies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Adviser mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio invests. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. From time to time, equity investments mayfall out of favor as compared to investments in debtsecurities, and vice versa. Small, less seasonedcompanies and medium-size companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies.

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2019, to waive anamount equal to any investment advisory fees indirectly incurredby the Portfolio as a result of its investment in any other mutualfund for which the Adviser or an affiliate serves as investmentadviser, other than Thrivent Cash Management Trust. Thiscontractual provision may be terminated upon the mutualagreement between the Independent Directors of the Portfolio andthe Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects the

effect of the contractual fee waiver and/or expensereimbursement.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 207% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achievea desired risk tolerance generally aligned with its peergroup as published by Lipper, Inc. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,debt securities and equity securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes may be based on maturity,duration, security type or credit rating (high yield—commonly known as “junk bonds”—or investmentgrade) for debt securities. Sub-classes for equitysecurities may be based on market capitalization,investment style (such as growth or value), or economicsector and may include leveraged loans, which aresenior secured loans that are made by banks or otherlending institutions to companies that are rated belowinvestment grade.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments. The Portfolio

may also enter into credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets ordebt markets would have a material adverse effect onthe Portfolio’s total returns given its significantallocation to equity securities and debt securities.Therefore, a principal risk of investing in the Portfolio isthat the allocation strategies used and the allocationdecisions made will not produce the desired results.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes in

A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Principal StrategiesThe Portfolio tries to produce current income whilemaintaining liquidity by investing at least 99.5% of itstotal assets in government securities, cash andrepurchase agreements collateralized fully bygovernment securities or cash. Government securitiesare any securities issued or guaranteed as to principal orinterest by the United States, or by a person controlledor supervised by and acting as an instrumentality of thegovernment of the United States pursuant to authoritygranted by the Congress of the United States; or anycertificate of deposit for any of the foregoing.

The Adviser manages the Portfolio subject to strict rulesestablished by the Securities and Exchange Commissionthat are designed so that the Portfolio may maintain astable $1.00 share price. Those rules generally requirethe Portfolio, among other things, to invest only inhigh quality securities that are denominated in U.S.dollars and have short remaining maturities. Inaddition, the rules require the Portfolio to maintain adollar-weighted average maturity (WAM) of not morethan 60 days and a dollar-weighted average life (WAL) ofnot more than 120 days. When calculating its WAM, thePortfolio may shorten its maturity by using the interestrate resets of certain adjustable rate securities. Generally,the Portfolio may not take into account these resetswhen calculating its WAL.

The Adviser typically uses U.S. Treasury securities,short-term discount notes issued by government-relatedorganizations and government securities payable withinseven-days or less to provide liquidity for reasonablyforeseeable shareholder redemptions and to complywith regulatory requirements. The Adviser invests inother securities by selecting from the available supply ofshort-term government securities based on its interestrate outlook and analysis of quantitative and technicalfactors. Although the Portfolio frequently holdssecurities until maturity, the Adviser may sell securitiesto increase liquidity. The Adviser will select securities forsuch sales based on how close the sale price would be totheir amortized costs.

Principal RisksYou could lose money by investing in the Portfolio.Although the Portfolio seeks to preserve the value ofyour investment at $1.00 per share, it cannot guaranteeit will do so. An investment in the Portfolio is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. ThePortfolio’s sponsor has no legal obligation to providefinancial support to the Portfolio, and you should notexpect that the sponsor will provide financial support to

the Portfolio at any time. In addition, the Portfolio issubject to the following principal investment risks.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio. Credit risk isexpected to be low for the Portfolio because of itsinvestments in government securities.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as FederalHome Loan Bank Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Bank Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Bank Fannie Mae and Freddie Mac are not backedby the full faith and credit of the U.S. government. Noassurance can be given that the U.S. government wouldprovide financial support to its agencies andinstrumentalities if not required to do so by law. Inaddition, the value of U.S. government securities may beaffected by changes in the credit rating of the U.S.government.

Interest Rate Risk. A weak economy, strong equitymarkets, or changes by the Federal Reserve in itsmonetary policies may cause short-term interest rates toincrease and affect the Portfolio’s ability to maintain astable share price.

Redemption Risk. The Portfolio may need to sellportfolio securities to meet redemption requests. ThePortfolio could experience a loss when selling portfoliosecurities to meet redemption requests if there is (i)significant redemption activity by shareholders,including, for example, when a single investor or fewlarge investors make a significant redemption ofPortfolio shares, (ii) a disruption in the normaloperation of the markets in which the Portfolio buysand sells portfolio securities or (iii) the inability of thePortfolio to sell portfolio securities because suchsecurities are illiquid. In such events, the Portfolio couldbe forced to sell portfolio securities at unfavorable pricesin an effort to generate sufficient cash to pay redeemingshareholders. Although the Portfolio does not have theability to impose liquidity fees or temporarily suspendredemptions, the Portfolio may deny the payment ofredemption proceeds or suspend redemptions during itsliquidation when permitted by applicable regulations.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing the Portfolio’s average annual returnsfor one-, five- and ten-year periods. Call 800-847-4836or visit Thrivent.com for performance results current tothe most recent month-end.

The bar chart and table include the effects of Portfolioexpenses and assume that you sold your investment atthe end of the period. On February 1, 2016, thePortfolio changed its investment strategies from those ofa prime money market fund to those of a governmentmoney market fund. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio.

1 Certain other expense categories have been adjusted to annualizeexpenses after the initial short year to reflect current fees.

2 The Adviser has contractually agreed, through at least April 30,2019, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent MultidimensionalIncome Portfolio in order to limit the Total Annual PortfolioOperating Expenses After Fee Waivers and/or ExpenseReimbursements, if any, to an annual rate of 0.95% of the averagedaily net assets of the shares. This contractual provision, however,may be terminated before the indicated termination date upon themutual agreement between the Independent Directors of thePortfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. The

example assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

ThriventMultidimensionalIncome Portfolio $117 $459 $824 $1,852

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance.

From inception on April 28, 2017 through the mostrecent fiscal year, the Portfolio’s portfolio turnover ratewas 172% of the average value of its portfolio.

Principal StrategiesThe Portfolio seeks to achieve its investment objectivesby allocating assets across multiple income and growthproducing asset classes and strategies. Debt securities inwhich the Portfolio invests include high yield, high riskbonds, notes, debentures and other debt obligationscommonly known as “junk bonds.” At the time ofpurchase, these high-yield securities are rated within orbelow the “BB” major rating category by S&P or the“Ba” major rating category by Moody’s or are unratedbut considered to be of comparable quality by theAdviser. The Portfolio also invests in leveraged loans,which are senior secured loans that are made by banksor other lending institutions to companies that are ratedbelow investment grade. In addition, the Portfolio mayinvest in investment-grade corporate bonds,asset-backed securities, mortgage-backed securities(including commercially backed ones), convertiblebonds, and U.S. dollar denominated emerging marketssovereign debt.

The Portfolio may invest in income-producing securitiesissued by closed-end funds (“CEFs”), publicly-tradedbusiness development companies (“BDCs”), masterlimited partnerships (“MLPs”), and exchange-traded

Page 147: Flexible Premium Deferred Variable Annuity · PDF fileFlexible Premium Deferred Variable Annuity Issued by Lutheran Brotherhood between 2/3/1994 and 4/30/2003. Prospectuses April 30,

funds (“ETFs”). CEFs are investment companies thatissue a fixed number of shares that trade on a stockexchange or over-the-counter, typically at a premium ora discount to their net asset value. BDCs are publiclyheld investment funds that invest primarily in privateand thinly traded public U.S. businesses. MLPs arepublicly-traded limited partnerships that are limited bythe Internal Revenue Code to only apply to enterprisesthat engage in certain businesses, mostly pertaining tothe use of natural resources. ETFs are investmentcompanies generally designed to track the performanceof a securities or other index or benchmark. ThePortfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Portfolio may also invest in income-producingequity securities, including preferred stock and realestate investment trusts (“REITs”).

The Portfolio may utilize derivatives for investmentexposure or hedging purposes, including futuresagreements and credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non- standardized derivatives contractstraded in the over-the-counter market.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Business Development Company (“BDC”) Risk.The value of a BDC’s investments will be affected byportfolio company specific performance as well as theoverall economic environment. Shares of BDCs maytrade at prices that reflect a premium above or adiscount below the investment company’s net assetvalue, which may be substantial. The Portfolio may beexposed to greater risk and experience higher volatilitythan would a portfolio that was not invested in BDCs.Additionally, most BDCs employ leverage which canmagnify the returns of underlying investments.

Closed-End Fund (“CEF”) Risk. Investments in CEFsare subject to various risks, including reliance onmanagement’s ability to meet a CEF’s investment

objective and to manage a CEF’s portfolio; fluctuation inthe market value of a CEF’s shares compared to thechanges in the value of the underlying securities thatthe CEF owns (i.e., trading at a discount or premium toits net asset value); and that CEFs are permitted toinvest in a greater amount of “illiquid” securities thantypical mutual funds. The Portfolio is subject to apro-rata share of the management fees and expenses ofeach CEF in addition to the Portfolio’s management feesand expenses, resulting in Portfolio shareholders subjectto higher expenses than if they invested directly inCEFs.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign and Emerging Markets Securities Risk.Foreign securities are generally more volatile than theirdomestic counterparts, in part because of higher

2

TSF-99

Page 148: Flexible Premium Deferred Variable Annuity · PDF fileFlexible Premium Deferred Variable Annuity Issued by Lutheran Brotherhood between 2/3/1994 and 4/30/2003. Prospectuses April 30,

political and economic risks, lack of reliable informationand fluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments may

prove incorrect, resulting in losses or poor performance,even in rising markets.

Investment in Other Investment Companies Risk.Investing in other investment companies, includingCEFs and BDCs, could result in the duplication ofcertain fees, including management and administrativefees, and may expose the Portfolio to the risks ofowning the underlying investments that the otherinvestment company holds.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds have aless liquid resale market. In addition, dealer inventoriesof bonds are at or near historic lows in relation tomarket size, which has the potential to decreaseliquidity and increase price volatility in the fixedincome markets, particularly during periods ofeconomic or market stress. As a result, the Adviser mayhave difficulty selling or disposing of securities quicklyin certain markets or may only be able to sell theholdings at prices substantially less than what theAdviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities markets

may also decline because of factors that affect aparticular industry.

Master Limited Partnership Risk. An investment inan MLP exposes the Portfolio to the legal and tax risksassociated with investing in partnerships. MLPs mayhave limited financial resources, their securities may berelatively illiquid, and they may be subject to moreerratic price movements because of the underlyingassets they hold. Due to the tax requirements for MLPs,the income of many MLPs comes from energyinfrastructure. Risks inherent in the energyinfrastructure business include: sustained declines indemand for crude oil, natural gas and refined petroleumproducts, construction risk, changes in the regulatoryenvironment or other regulatory exposure, weather risk,risks associated with terrorist activity and interest raterisk.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,

traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of the

Thrivent Opportunity Income Plus PortfolioInvestment ObjectiveThrivent Opportunity Income Plus Portfolio (the�Portfolio�) seeks a combination of current income andlong-term capital appreciation.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.50%

Other Expenses 0.15%

Acquired Fund Fees and Expenses 0.04%

Total Annual Portfolio Operating Expenses 0.69%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent OpportunityIncome Plus Portfolio $70 $221 $384 $859

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 218% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests in abroad range of debt securities and may invest in equitysecurities to a limited extent.

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade. In addition, thePortfolio may invest in investment-grade corporatebonds, asset-backed securities, mortgage-backedsecurities (including commercially backed ones),convertible bonds, and sovereign and emerging marketdebt (both U.S. dollar and non-U.S. dollardenominated).

The Portfolio may also invest in income-producingequity securities, including preferred stock and realestate investment trusts (“REITs”).

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. In particular, underperformance in the fixedincome markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to fixed income securities. Therefore, aprincipal risk of investing in the Portfolio is that theallocation strategies used and the allocation decisionsmade will not produce the desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which may

be magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to make

TSF-105

principal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveraged

loans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, while

3

Page 155: Flexible Premium Deferred Variable Annuity · PDF fileFlexible Premium Deferred Variable Annuity Issued by Lutheran Brotherhood between 2/3/1994 and 4/30/2003. Prospectuses April 30,

mortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Bonds may exhibit price fluctuations due tochanges in interest rates or bond yield levels.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. These indices arethe Bloomberg Barclays U.S. Mortgage-Backed SecuritiesIndex, which covers the mortgage-backed securitiescomponent of the Bloomberg Barclays U.S. AggregateBond Index, the Bloomberg Barclays U.S. High YieldBa/B 2% Issuer Capped Index, which represents theperformance of high yield corporate bonds rated Ba orB, with a maximum allocation of 2% to any one issuer,and the S&P/LSTA Leveraged Loan Index, which reflects

the performance of the largest facilities in the leveragedloan market. Call 800-847-4836 or visit Thrivent.comfor performance results current to the most recentmonth-end.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assume that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Effective August 16, 2013, based on approval of thePortfolio’s Board of Directors, the Portfolio’s investmentobjective and principal strategies were changed, whichhad the effect of converting the Portfolio from onewhich invested at least 80% of its assets inmortgage-related securities to one which invests in abroad range of fixed-income securities. At the sametime, the Portfolio’s name changed from ThriventMortgage Securities Portfolio to Thrivent OpportunityIncome Plus Portfolio. As a result, performanceinformation presented below with respect to periodsprior to August 16, 2013, reflects the performance of aninvestment portfolio that was materially different fromthe investment portfolio of Thrivent OpportunityIncome Plus Portfolio.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 51% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio’s principal strategy for achieving itsobjective is normally to invest the Portfolio’s assetsprimarily in common stocks.

FIAM LLC (“FIAM”), the Portfolio’s subadviser, is notconstrained by any particular investment style. At anygiven time, FIAM may tend to buy “growth” stocks or“value” stocks, or a combination of both types.

In buying and selling securities for the Portfolio, FIAMuses a disciplined approach that involvescomputer-aided, quantitative analysis supported byfundamental analysis. FIAM’s computer modelsystematically reviews thousands of stocks, using datasuch as historical earnings, dividend yield, earnings pershare, and other quantitative factors. Then, the issuersof potential investments are analyzed further usingfundamental factors such as growth potential, earningsestimates, and financial condition.

FIAM may use various techniques, such as buying andselling futures contracts and exchange-traded funds, toincrease or decrease the Portfolio’s exposure to changingsecurity prices or other factors that affect securityvalues. If FIAM’s strategies do not work as intended, thePortfolio may not achieve its objective.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and the

Portfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Certain securities (i.e.,small-cap stocks) often have a less liquid resale market.As a result, the Adviser or subadviser may have difficultyselling or disposing of securities quickly in certainmarkets or only be able to sell the holdings at pricessubstantially less than what the Adviser or subadviserbelieves they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move with

these cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Small and Mid Cap Risk. Smaller, less seasonedcompanies often have greater price volatility, lowertrading volume, and less liquidity than larger, moreestablished companies. These companies tend to havesmall revenues, narrower product lines, lessmanagement depth and experience, small shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies. Such companies seldom pay significantdividends that could cushion returns in a falling market.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared toa broad-based securities market index. The index is theS&P Composite 1500 Index, which combines the S&P500 Index, the S&P MidCap 400 Index, and the S&PSmallCap 600 Index to cover approximately 90% of theU.S. market capitalization. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Thrivent PartnerEmerging MarketsEquity Portfolio $122 $417 $734 $1,632

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 15% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes), at the time ofinitial purchase, in emerging market equities, includingcommon stock, preferred stock, convertible securities,depositary receipts and rights and warrants to buycommon stocks. A security is considered to be an“emerging market” security if issued by a company thatPortfolio management has determined meets one ormore of the following criteria:

• is organized under the laws of, or has its principaloffice in, an emerging market country;

• has its principal securities trading market in anemerging market country; and/or

• derives a majority of its annual revenue or earningsor assets from goods produced, sales made or servicesperformed in an emerging market country.

An “emerging market” country is any countrydetermined by the Adviser or subadviser to have anemerging market economy, considering factors such asthe country’s credit rating, its political and economicstability and the development of its financial andcapital markets. These emerging market countriesinclude every nation in the world except the U.S.,Canada, Israel, Japan, Australia, New Zealand, HongKong, Singapore and all nations typically consideredpart of Western Europe. At times, the Portfolio mayhave a significant amount of its assets invested in acountry or geographic region.

The Portfolio may also invest in equity securities ofissuers that are not tied economically to emergingmarket countries. The Portfolio may invest in securitiesdenominated in U.S. dollars and currencies of emergingmarket countries in which it may invest. The Portfoliotypically has full currency exposure to those markets inwhich it invests.

The Portfolio may invest in securities of any marketcapitalization, including small and mid-cap securities.

The Portfolio may invest in securities of any marketsector and may hold a significant amount of securitiesof companies, from time to time, within a single sectorsuch as financials.

The Portfolio’s subadviser, Aberdeen Asset ManagersLimited (“Aberdeen”), uses a disciplined investmentprocess based on its proprietary research to determinesecurity selection. Aberdeen seeks to identify “quality”companies, based on factors such as strength ofmanagement and business, that trade at reasonablevaluations, based on factors such as earnings growthand other key financial measurements. Aberdeen alsoconsiders how a company’s corporate governance andrisk management practices may affect that company’slong-term value. Aberdeen makes investments for thelong-term, although it may sell a security when itperceives a company’s business direction or growthprospects to have changed or the company’s valuationsare no longer attractive.

Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its net assetsinvested in emerging market equities from 80% to alesser amount, it will notify you at least 60 days prior tothe change.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and events

in any one country could cause the Portfolio’s shareprice to decline.

Financial Sector Risk. To the extent that thefinancials sector continues to represent a significantportion of the Portfolio, the Portfolio will be sensitive tochanges in, and its performance may depend to agreater extent on, factors impacting this sector.Performance of companies in the financials sector maybe adversely impacted by many factors, including,among others, government regulations, economicconditions, credit rating downgrades, changes ininterest rates, and decreased liquidity in credit markets.The impact of more stringent capital requirements,recent or future regulation of any individual financialcompany or recent or future regulation of the financialssector as a whole cannot be predicted. In recent years,cyber attacks and technology malfunctions and failureshave become increasingly frequent in this sector andhave caused significant losses.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Foreign Securities Risk. Securities of foreigncompanies in which the Portfolio invests generally carrymore risk than securities of U.S. companies. Theeconomies and financial markets of certain regions –such as Latin America, Asia, Europe, and theMediterranean region – can be highly interdependentand may decline at the same time. Other risks resultfrom the varying stages of economic and politicaldevelopment of foreign countries; the differingregulatory environments, trading days, and accountingstandards of foreign markets; and higher transactioncosts. The Portfolio’s investment in any country couldbe subject to governmental actions such as capital orcurrency controls, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment of

investments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Certain securities (i.e.,small-cap stocks and foreign securities) often have a lessliquid resale market. As a result, the Adviser orsubadviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser or subadviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantially

less liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldcushion returns in a falling market.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one- and five-year periods and sinceinception compared to a broad-based securities marketindex. The index is the MSCI Emerging Markets Index -USD Net Returns, which measures the performance ofstock markets in developing countries throughout theworld. Call 800-847-4836 or visit Thrivent.com forperformance results current to the most recentmonth-end.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assume that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Thrivent Partner Growth Stock PortfolioInvestment ObjectivesThe investment objective of the Thrivent PartnerGrowth Stock Portfolio (the �Portfolio�) is to achievelong-term growth of capital and, secondarily, increasedividend income.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.65%

Other Expenses 0.14%

Total Annual Portfolio Operating Expenses 0.79%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent PartnerGrowth StockPortfolio $81 $252 $439 $978

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 52% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio’s principal strategy for achieving itsinvestment objectives under normal circumstances is toinvest at least 80% of net assets (plus the amount of anyborrowing for investment purposes) in common stocks.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in common stocks from 80% to a lesseramount, it will notify you at least 60 days prior to sucha change.

The Portfolio concentrates its investments in growthcompanies. The Portfolio’s subadviser, T. Rowe PriceAssociates, Inc. (“T. Rowe Price”), seeks investments incompanies that have the ability to pay increasingdividends through strong cash flow. The subadvisergenerally looks for companies with an above-averagerate of earnings growth and a lucrative niche in theeconomy that gives them the ability to sustain earningsmomentum even during times of slow economicgrowth. T. Rowe Price believes that when a companyincreases its earnings faster than both inflation and theoverall economy, the market will eventually reward itwith a higher stock price. The Portfolio may at timesinvest significantly in technology stocks.

In pursuing the Portfolio’s investment objectives, T.Rowe Price has the discretion to purchase somesecurities that do not meet its normal investmentcriteria, as described above, when it believes suchpurchase will provide an opportunity for substantialappreciation. These situations might arise when T. RowePrice believes a security could increase in value for avariety of reasons including a change in management,an extraordinary corporate event, a new productintroduction or innovation, or a favorable competitivedevelopment.

While the Portfolio invests primarily (at least 80%) incommon stocks, it may also invest in foreign stocks (upto 30% of total assets), and futures and options toobtain investment exposure or for hedging, in keepingwith the Portfolio’s objectives.

The Portfolio may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsinto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objectives.

Derivatives Risk. The use of derivatives (such asfutures and options) involves additional risks andtransaction costs which could leave the Portfolio in aworse position than if it had not used theseinstruments. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. To the extent the Portfolio isexposed to foreign securities, it is subject to various risksassociated with such securities. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of the Portfolio’s investmentstrategy depends significantly on the skills of theAdviser or subadviser in assessing the potential of theinvestments in which the Portfolio invests. This

assessment of investments may prove incorrect,resulting in losses or poor performance, even in risingmarkets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projection offuture earnings or revenues and, if a company’s earningsor revenues fall short of expectations, its stock pricemay fall dramatically.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared to

Thrivent PartnerHealthcare Portfolio $90 $291 $510 $1,138

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 212% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio will invest atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in the securities ofcompanies that are engaged in the development,production or distribution of pharmaceutical, generic,biotechnology and medical technology products orservices (“healthcare companies”). Healthcarecompanies are those that derive at least 50% of theirannual revenues from the production of such productsand provision of such services or have at least 50% oftheir assets in such products or services. The Portfolioinvests primarily in equity securities of both U.S. andnon-U.S. companies (including American DepositaryReceipts and issuers in emerging markets) and, as anon-diversified fund under the Investment CompanyAct of 1940 (the “1940 Act”), focuses its investments inthe securities of a relatively few number of issuers. Inaddition, the Portfolio concentrates its investments inthe securities of companies in the healthcare industry,some of which may be small- and medium-sizedcompanies. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in the securities of healthcarecompanies from 80% to a lesser amount, it will notifyyou at least 60 days prior to the change.

BlackRock Investment Management, LLC, the Portfolio’ssubadviser, considers a variety of factors when choosinginvestments for the Portfolio, including (i) identifyingcompanies and industries that appear to have thepotential for above-average returns; and (ii) identifyingcompanies that are expected to show above-averagegrowth over the long-term, as well as those that appear

to be trading below their true worth. The Portfolio willgenerally sell a stock when, in the opinion of thesubadviser, the stock reaches its price target or if there isdeterioration in the company’s fundamentals, a changein macroeconomic outlook, technical deterioration,valuation issues, a need to rebalance the Portfolio or abetter opportunity elsewhere.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Healthcare Industry Risk. As a sector fund thatinvests primarily in the healthcare industry, thePortfolio is subject to the risk that the companies in that

industry are likely to react similarly to legislative orregulatory changes, adverse market conditions and/orincreased competition affecting their market segment.Due to the rapid pace of technological development,there is the risk that the products and servicesdeveloped by these companies may become rapidlyobsolete or have relatively short product cycles. There isalso the risk that the products and services offered bythese companies will not meet expectations or evenreach the marketplace.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty. Common stock of a company issubordinate to other securities issued by the company. Ifa company becomes insolvent, interests of investorsowning common stock will be subordinated to theinterests of other investors in, and general creditors of,the company.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financial

resources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Stocks of growth companies historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projectionsof future earnings or revenues and if a company’searnings or revenues fall short of expectations its stockprice may fall dramatically.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one- and five-year periods and sinceinception compared to a broad-based securities marketindex. The index is the S&P Composite 1500® Index,which measures the performance of stocks in the S&P1500® Index that are classified as members of the GICS®

health care sector. The Portfolio no longer uses theMSCI World Healthcare Index, which is acapitalization-weighted index of selected health carestocks from around the world, because BlackRockInvestment Management, LLC replaced Sectoral AssetManagement Inc.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 88% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio seeks to achieve its objective by investingprimarily in equity and debt securities of issuersthroughout the world. The Portfolio seeks to diversify itsportfolio broadly among developed and emergingcountries and among multiple asset classes. Undernormal market conditions, the Portfolio invests at least40% of its net assets in foreign assets. If marketconditions are not deemed favorable by the Portfolio’sinvestment adviser, the Portfolio could invest a lowerpercentage, but at least 30% of its net assets in foreignassets. A foreign asset could be an investment in anissuer that is organized under the laws of a foreignjurisdiction; that is traded principally in a foreigncountry; that derives at least 50% of its revenues orprofits from goods produced or sold, investments made,or services performed in a foreign country or has at least50% of its assets in a foreign country; or that otherwiseexposes the Portfolio’s portfolio to the economicfortunes and risks of a foreign country.

The debt securities in which the Portfolio invests maybe of any maturity or credit quality and may includehigh-yield, high-risk bonds, notes, debentures and otherdebt obligations commonly known as “junk bonds.” Atthe time of purchase, these high-yield, high-risk debtsecurities are rated within or below the “BB” majorrating category by Standard & Poor’s or the “Ba” majorrating category by Moody’s or are unrated butconsidered to be of comparable quality. The interestrates of the Portfolio’s debt securities may be fixed,floating or subject to periodic reset provisions. The debtsecurities in which the Portfolio invests may includesecurities issued by sovereign entities in foreign andemerging market countries. Such sovereign entitiesinclude foreign and emerging market governments,their agencies and instrumentalities, or their centralbanks.

The Adviser will make asset allocation decisions amongthe various asset classes and has selected multiplesubadvisers to manage each such class, although theAdviser will directly manage the Portfolio’sinternational large-cap value assets and assets that areallocated to U.S. securities. The subadvisers investindependently of one another and use their ownmethodologies for selecting assets.

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformances among asset classes. These allocationsmay change without shareholder approval or advancenotice to shareholders to the extent consistent withapplicable law.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

Principal Global Investors, LLC manages theinternational large-cap growth assets. Aberdeen AssetManagers Limited manages the emerging markets equityassets. Goldman Sachs Asset Management, L.P. managesthe international small- and mid-cap equities and theemerging markets debt assets. The Adviser manages theinternational large-cap value assets and the assetsallocated to U.S. securities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, among

other things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Foreign Securities Risk. Securities of foreigncompanies in which the Portfolio invests generally carrymore risk than securities of U.S. companies. Theeconomies and financial markets of certain regions –such as Latin America, Asia, Europe, and theMediterranean region – can be highly interdependentand may decline at the same time. Other risks resultfrom the varying stages of economic and politicaldevelopment of foreign countries; the differingregulatory environments, trading days, and accountingstandards of foreign markets; and higher transactioncosts. The Portfolio’s investment in any country couldbe subject to governmental actions such as capital orcurrency controls, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Page 179: Flexible Premium Deferred Variable Annuity · PDF fileFlexible Premium Deferred Variable Annuity Issued by Lutheran Brotherhood between 2/3/1994 and 4/30/2003. Prospectuses April 30,

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Certain securities (i.e.,small-cap stocks and foreign securities) often have a lessliquid resale market. As a result, the Adviser orsubadviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser or subadviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Multi-Manager Risk. The investment styles employedby the subadvisers may not be complementary. Theinterplay of the various strategies employed by thesubadvisers may result in the Portfolio indirectly

holding positions in certain types of securities,industries or sectors. These positions may bedetrimental to a Portfolio’s performance dependingupon the performance of those securities and the overalleconomic environment. The multi-manager approachcould result in a high level of portfolio turnover,resulting in higher brokerage expenses and increased taxliability from a Portfolio’s realization of capital gains. Itis also possible that one subadviser could be selling aparticular security or security from a certain countrywhile another subadviser could be purchasing the samesecurity or a security from that same country.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projectionsof future earnings or revenues and, if a company’searnings or revenues fall short of expectations, its stockprice may fall dramatically. Value style investingincludes the risk that stocks of undervalued companiesmay not rise as quickly as anticipated if the market

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 15% ofthe average value of its portfolio.

Principal StrategiesIn seeking to achieve its investment objective, thePortfolio focuses on income-producing common stocksand other equity securities of U.S. real estate companies.Under normal circumstances, the Portfolio invests atleast 80% of its net assets (plus any borrowings forinvestment purposes) in companies that are primarilyengaged in the real estate industry. This includescompanies such as real estate investment trusts (REITs)and other real estate related investments. A real estatecompany generally derives at least 50% of its revenuefrom real estate ownership, leasing, management,development, financing or sale of residential,commercial or industrial real estate—or has at least 50%of its assets in real estate. Should the Adviser determinethat the Portfolio would benefit from reducing thepercentage of assets invested in companies that areprimarily engaged in the real estate industry from 80%to a lesser amount, it will notify you at least 60 daysprior to such a change.

This Portfolio may invest up to 20% of its assets inequity and fixed income securities of companies whichare not principally engaged in the real estate industry orwhich are not income producing equity securities ofcompanies principally engaged in the U.S. real estateindustry.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Interest Rate Risk. Interest rate risk is the risk thatsecurity prices (equity or fixed income) decline in valuewhen interest rates rise. This effect of rising interestrates is generally more pronounced for high dividend

paying stock than for stocks that pay little or nodividends. This may cause the value of real estatesecurities to decline during periods of rising interestrates, which would reduce the overall return of thePortfolio. Changes by the Federal Reserve to monetarypolicies could affect interest rates and the value of somesecurities

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Real Estate Industry Risk. To the extent thePortfolio allocates assets to companies in the real estatebusiness, the Portfolio is subject to real estate industryrisk. Declines in real estate values, changes in interestrates or economic downturns can have a significantnegative effect on companies in the real estate industry.Other adverse changes could include, but are notlimited to, extended vacancies of properties, increasedcompetition, overbuilding and changes in zoning lawand government regulations.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality of

the mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared toa broad-based securities market index. The index is theS&P Composite 1500® Equity REITs Index, whichmeasures the performance of the stocks in the S&PComposite 1500® Index that are classified as membersof the GICS® Equity Real Estate Investment Trustsindustry. The Portfolio now compares its returns to theS&P Composite 1500® Equity REITs Index because thePortfolio’s complex no longer uses FTSE as an indexprovider. Call 800-847-4836 or visit Thrivent.com forperformance results current to the most recentmonth-end.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assumes that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Thrivent Small Cap Growth PortfolioInvestment ObjectiveThrivent Small Cap Growth Portfolio (the �Portfolio�)seeks long-term capital growth. The Portfolio’sinvestment objective may be changed withoutshareholder approval.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.80%

Other Expenses1 2.81%

Total Annual Portfolio Operating Expenses 3.61%

Less Fee Waivers and/or ExpenseReimbursements2 2.64%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.97%

1 These expenses are based on estimated amounts for the currentfiscal year.

2 The Adviser has contractually agreed, through at least April 30,2019, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent Small Cap GrowthPortfolio in order to limit the Total Annual Portfolio OperatingExpenses After Fee Waivers and/or Expense Reimbursements, if any,to an annual rate of 0.97% of the average daily net assets of theshares. This contractual provision, however, may be terminatedbefore the indicated termination date upon the mutual agreementbetween the Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. In

addition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years

Thrivent Small Cap GrowthPortfolio $99 $861

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. Because the Portfolio had notyet commenced operations prior to the date of thisprospectus, the Portfolio’s portfolio turnover rate for themost recent fiscal year is not yet available.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof small companies. The Adviser focuses mainly in theequity securities of smaller U.S. companies which havemarket capitalizations equivalent to those companiesincluded in widely known indices such as the S&PSmallCap 600 Index, the MSCI USA Small Cap Index, orthe small company market capitalization classificationpublished by Lipper, Inc. These companies typicallyhave a market capitalization of less than $6 billion.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in equity securities of small companies stocksfrom 80% to a lesser amount, we will notify you at least60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques and focuses on stocks ofcompanies that it believes have demonstrated andbelieves will sustain above-average revenue and earningsgrowth over time, or which are expected to developrapid sales and earnings growth in the future whencompared to the economy and stock market as a whole.Many such companies are in the technology sector and

the Portfolio may at times have a higher concentrationin this industry.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Small capitalizationstocks often have a less liquid resale market. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities markets

may also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldcushion returns in a falling market.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projection offuture earnings or revenues and, if a company’s earningsor revenues fall short of expectations, its stock pricemay fall dramatically.

PerformanceNo performance information for the Portfolio isprovided because it commenced operations on April 30,2018. Call 800-847-4836 or visit Thrivent.com forperformance results current to the most recentmonth-end that takes place after April 30, 2018.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 16% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in small company common stocksincluded in the S&P SmallCap 600 Index in theproportions in which they are represented in the Index.This is a passively managed Portfolio, which means thatthe Adviser does not choose the securities that make upthe Portfolio. The S&P SmallCap 600 Index is acapitalization-weighted index comprised of 600domestic small capitalization stocks chosen for marketsize, liquidity, and industry representation. Accordingly,the Portfolio invests in stocks of smaller companiesfrom a broad range of industries. The S&P SmallCap 600Index is adjusted quarterly, and when changes to theindex occur, the Adviser will attempt to replicate thesechanges within the Portfolio. However, any suchchanges may result in slight variations from time totime. The Portfolio may buy and sell equity indexfutures for investment exposure. For liquidity reasons,the Portfolio may invest to some degree in moneymarket instruments. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 44% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof small companies. The Adviser focuses mainly in theequity securities of smaller U.S. companies which havemarket capitalizations equivalent to those companiesincluded in widely known indices such as the S&PSmallCap 600 Index, MSCI USA Small Cap Index, or thesmall company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of less than $6 billion.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in equity securities of small companies stocksfrom 80% to a lesser amount, we will notify you at least60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques to determine whatsecurities to buy and sell. Fundamental techniquesassess a security’s value based on an issuer’s financialprofile, management, and business prospects whilequantitative and technical techniques involve a moredata-oriented analysis of financial information, markettrends and price movements. The Adviser looks forsmall companies that, in its opinion:

• have an improving fundamental outlook;• have capable management; and• are financially sound.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Small capitalizationstocks often have a less liquid resale market. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Such

companies seldom pay significant dividends that couldcushion returns in a falling market.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index.

Call 800-847-4836 orvisit Thrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.
