Investment Objective. The Portfolio seeksabove-average capital appreciation.

Principal Investment Strategy. The Portfolioinvests in stocks of domestic companies selected byapplying separate uniquely specialized enhanced sectorstrategies1. Invesco Capital Markets, Inc., the Sponsor,implemented the Portfolio strategy using informationavailable as of the close of business on November 30,2017 (the “Selection Date”). The Portfolio strategycombines ten enhanced sector strategies: the BasicMaterials Strategy, the Consumer Goods Strategy, theConsumer Services Strategy, the Energy Strategy, theFinancials Strategy, the Health Care Strategy, theIndustrials Strategy, the Technology Strategy, theTelecommunications Strategy and the Utilities Strategy.Please refer to “Portfolio Strategies” for details of eachenhanced sector strategy. Each strategy makes up thatpercentage of the initial Portfolio as its respective sectormakes up of the Dow Jones U.S. Index. Although eachenhanced sector strategy is designed to produce acertain number of stocks, it is possible that a particularstrategy could produce less. In particular, theTelecommunications Strategy produced only 5 stocksinstead of 10 for this series of the Portfolio. When thePortfolio terminates you can elect to follow the strategy byredeeming your Units and reinvesting the proceeds in anew portfolio, if available.

The Dow Jones U.S. Index is a widely adoptedmeasure of the U.S. stock market. It is made up ofapproximately 95% of U.S. stocks, and weighted byfloat-adjusted market capitalization, excluding the mostthinly traded securities. The Dow Jones U.S. Index isbroken down into 10 sector indexes including the DowJones U.S. Basic Materials Index, the Dow Jones U.S.Consumer Goods Index, the Dow Jones U.S. ConsumerServices Index, the Dow Jones U.S. Financials Index,the Dow Jones U.S. Health Care Index, the Dow JonesU.S. Industrials Index, the Dow Jones U.S. Oil & GasIndex, the Dow Jones U.S. Technology Index, the DowJones U.S. Telecommunications Index and the DowJones U.S. Utilities Index.

1 An enhanced index strategy, or in this case, an enhanced sectorstrategy, refers to a unit investment trust strategy, sponsored by InvescoCapital Markets, Inc., that seeks to outperform an index by investing inan objectively selected subset of stocks from the same index.

Of course, we cannot guarantee that your Portfoliowill achieve its objective. The value of your Units may fallbelow the price you paid for the Units. You should readthe “Risk Factors” section before you invest.

The Portfolio is designed as part of a long-terminvestment strategy. The Sponsor may offer asubsequent series of the portfolio when the currentPortfolio terminates. As a result, you may achieve moreconsistent overall results by following the strategythrough reinvestment of your proceeds over severalyears if subsequent series are available. Repeatedlyrolling over an investment in a unit investment trust maydiffer from long-term investments in other investmentproducts when considering the sales charges, fees,expenses and tax consequences attributable to aUnitholder. For more information see “Rights ofUnitholders--Rollover”.

Principal Risks. As with all investments, you canlose money by investing in this Portfolio. The Portfolioalso might not perform as well as you expect. This canhappen for reasons such as these:

• Security prices will fluctuate. The value ofyour investment may fall over time.

• An issuer may be unwilling or unable todeclare dividends in the future, or mayreduce the level of dividends declared.This may result in a reduction in the value ofyour Units.

• The financial condition of an issuer mayworsen or its credit ratings may drop,resulting in a reduction in the value ofyour Units. This may occur at any point intime, including during the initial offering period.

• You could experience dilution of yourinvestment if the size of the Portfolio isincreased as Units are sold. There is noassurance that your investment will maintain itsproportionate share in the Portfolio’s profits andlosses.

• The Portfolio’s performance might notsufficiently correspond to publishedhypothetical performance of thePortfolio’s investment strategy. This can

happen for reasons such as an inability toexactly replicate the weightings of stocks in thestrategy or be fully invested, timing of thePortfolio offering or timing of your investment,and Portfolio expenses. The hypotheticalperformance presented is not the pastperformance of the Portfolio.

• The Portfolio invests in stocks ofsmaller capitalization companies. Thesestocks are often more volatile and have lowertrading volumes than stocks of largercompanies. Smaller capitalization companiesmay have l imited products or f inancialresources, management inexperience and lesspublicly available information.

• We do not actively manage the Portfolio.Except in limited circumstances, the Portfolio willhold, and may continue to buy, shares of thesame securities even if their market valuedeclines.

Example

This example helps you compare the cost of the Portfolio with otherunit trusts and mutual funds. In the example we assume that the expensesdo not change and that the Portfolio’s annual return is 5%. Your actualreturns and expenses will vary. This example also assumes that youcontinue to follow the Portfolio strategy and roll your investment, includingall distributions, into a new trust each year subject to a sales charge of1.85%. Based on these assumptions, you would pay the followingexpenses for every $10,000 you invest in the Portfolio:

1 year $ 281 3 years 860 5 years 1,464 10 years 3,083

* The estimated annual expenses are based upon the estimated trustsize for the Portfolio determined as of the initial date of deposit.Because certain of the operating expenses are fixed amounts, if thePortfolio does not reach the estimated size, or if the value of thePortfolio or number of outstanding units decline over the life of the trust,or if the actual amount of the operating expenses exceeds theestimated amounts, the actual amount of the operating expenses per100 units would exceed the estimated amounts. In some cases, theactual amount of operating expenses may substantially differ from theamounts reflected above.

The maximum sales charge is 1.85% of the Public Offering Priceper Unit. There is no initial sales charge at a Public Offering Price of $10or less. If the Public Offering Price exceeds $10 per Unit, the initial salescharge is the difference between the total sales charge (maximum of1.85% of the Public Offering Price) and the sum of the remainingdeferred sales charge and the creation and development fee. Thedeferred sales charge is fixed at $0.135 per Unit and accrues daily fromApril 10, 2018 through September 9, 2018. Your Portfolio pays aproportionate amount of this charge on the 10th day of each monthbeginning in the accrual period until paid in full. The combination of theinitial and deferred sales charges comprises the “transactional salescharge”. The creation and development fee is fixed at $0.05 per Unit andis paid at the earlier of the end of the initial offering period (anticipated tobe three months) or six months following the Initial Date of Deposit. Formore detail, see “Public Offering Price - General.”

The table below compares the hypothetical totalreturn of stocks selected using the Portfolio’s investmentstrategy (the “Hypothetical Strategy Stocks”) with thestocks in the Dow Jones U.S. Index. Hypothetical totalreturn includes any dividends paid on the stockstogether with any increase or decrease in the value ofthe stocks. The table illustrates a hypothetical investmentin the Hypothetical Strategy Stocks at the beginning ofeach year -- similar to buying Units of the Portfolio,redeeming them after one year and reinvesting theproceeds in a new portfolio each year.

These hypothetical returns are not actual pastperformance of the Portfolio or prior series but do reflectthe sales charge or expenses you will pay. Of course,

these hypothetical returns are not guarantees of futureresults and the value of your Units will fluctuate. Due tothe application of the relevant screens described under“Portfolio Strategies”, small and mid-cap stocks are oftenmore highly represented in the Hypothetical StrategyStocks than in the Dow Jones U.S. Index, which incertain years, may result in significant differences inrelative hypothetical total returns. You should note thatthe returns shown below are hypothetical annual returnsbased on a calendar year investment. The performanceof the Portfolio may differ because the Portfolio has a 15month life that is not based on a calendar yearinvestment cycle. For more information about thehypothetical total return calculations, see “Notes toHypothetical Performance Tables”.

Investment Objective. The Portfolio seeksabove-average capital appreciation.

Principal Investment Strategy. The Portfolioinvests in stocks selected by applying three of thefollowing separate uniquely specialized enhanced sectorstrategies1: the Basic Materials Strategy, the ConsumerGoods Strategy, the Consumer Services Strategy, theEnergy Strategy, the Financials Strategy, the HealthCare Strategy, the Industrials Strategy, the TechnologyStrategy, the Telecommunications Strategy and theUtilities Strategy. Please refer to “Portfolio Strategies” fordetails of each enhanced sector strategy. InvescoCapital Markets, Inc., the Sponsor, implemented thePortfolio strategy using information available as of theclose of business on November 30, 2017 (the“Selection Date”). The Portfolio strategy first ranks theten Dow Jones U.S. Index sector indexes by the simpleaverage total return of the stocks in each index for theprevious six-month period and selects the three highestranking sector indexes. The Portfolio invests in thestocks selected using the three sector strategies basedon these three highest ranking sector indexes. Eachsector strategy makes up approximately one-third of theinitial Portfolio. When the Portfolio terminates you canelect to follow the strategy by redeeming your Units andreinvesting the proceeds in a new portfolio, if available.

The Dow Jones U.S. Index is a widely adoptedmeasure of the U.S. stock market. It is made up ofapproximately 95% of U.S. stocks, and weighted byfloat-adjusted market capitalization, excluding themost thinly traded securities. The Dow Jones U.S.Index is broken down into 10 sector indexesincluding the Dow Jones U.S. Basic Materials Index,the Dow Jones U.S. Consumer Goods Index, theDow Jones U.S. Consumer Services Index, the DowJones U.S. Financials Index, the Dow Jones U.S.Health Care Index, the Dow Jones U.S. IndustrialsIndex, the Dow Jones U.S. Oil & Gas Index, the DowJones U.S. Technology Index, the Dow Jones U.S.Telecommunications Index and the Dow Jones U.S.Utilities Index.

1 An enhanced index strategy, or in this case, an enhanced sectorstrategy, refers to a unit investment trust strategy, sponsored by InvescoCapital Markets, Inc., that seeks to outperform an index by investing inan objectively selected subset of stocks from the same index.

Of course, we cannot guarantee that your Portfoliowill achieve its objective. The value of your Units may fallbelow the price you paid for the Units. You should readthe “Risk Factors” section before you invest.

The Portfolio is designed as part of a long-terminvestment strategy. The Sponsor may offer asubsequent series of the portfolio when the currentPortfolio terminates. As a result, you may achievemore consistent overall results by following thestrategy through reinvestment of your proceeds overseveral years if subsequent series are available.Repeatedly rol l ing over an investment in a unitinvestment trust may differ from long-term investmentsin other investment products when considering thesales charges, fees, expenses and tax consequencesattributable to a Unitholder. For more information see“Rights of Unitholders--Rollover”.

Principal Risks. As with all investments, you canlose money by investing in this Portfolio. The Portfolioalso might not perform as well as you expect. This canhappen for reasons such as these:

• Security prices will fluctuate. The value ofyour investment may fall over time.

• An issuer may be unwilling or unable todeclare dividends in the future, or mayreduce the level of dividends declared.This may result in a reduction in the value ofyour Units.

• The financial condition of an issuer mayworsen or its credit ratings may drop,resulting in a reduction in the value ofyour Units. This may occur at any point intime, including during the initial offering period.

• You could experience dilution of yourinvestment if the size of the Portfolio isincreased as Units are sold. There is noassurance that your investment will maintain itsproportionate share in the Portfolio’s profitsand losses.

• The Portfolio’s performance might notsufficiently correspond to publishedhypothetical performance of the

11

Enhanced Sector Strategy, Sector Rotation Portfolio

12

Portfolio’s investment strategy. This canhappen for reasons such as an inability toexactly replicate the weightings of stocks in thestrategy or be fully invested, timing of thePortfolio offering or timing of your investment,and Portfolio expenses. The hypotheticalperformance presented is not the pastperformance of the Portfolio.

• The Portfolio invests in stocks ofsmaller capitalization companies. Thesestocks are often more volatile and have lowertrading volumes than stocks of largercompanies. Smaller capitalization companiesmay have l imited products or f inancialresources, management inexperience and lesspublicly available information.

• The Portfolio is concentrated insecurities issued by companies in thebasic materials sector, the financialssector and the industrials sector.Negative developments in any one of thesesectors will affect the value of your investmentmore than would be the case in a morediversified investment.

• We do not actively manage the Portfolio.Except in limited circumstances, the Portfoliowill hold, and may continue to buy, shares ofthe same securities even if their market valuedeclines.

Example

This example helps you compare the cost of the Portfolio with otherunit trusts and mutual funds. In the example we assume that theexpenses do not change and that the Portfolio’s annual return is 5%. Youractual returns and expenses will vary. This example also assumes thatyou continue to follow the Portfolio strategy and roll your investment,including all distributions, into a new trust each year subject to a salescharge of 1.85%. Based on these assumptions, you would pay thefollowing expenses for every $10,000 you invest in the Portfolio:

1 year $ 287 3 years 877 5 years 1,491 10 years 3,137

* The estimated annual expenses are based upon the estimated trustsize for the Portfolio determined as of the initial date of deposit.Because certain of the operating expenses are fixed amounts, if thePortfolio does not reach the estimated size, or if the value of thePortfolio or number of outstanding units decline over the life of the trust,or if the actual amount of the operating expenses exceeds theestimated amounts, the actual amount of the operating expenses per100 units would exceed the estimated amounts. In some cases, theactual amount of operating expenses may substantially differ from theamounts reflected above.

The maximum sales charge is 1.85% of the Public Offering Priceper Unit. There is no initial sales charge at a Public Offering Price of $10or less. If the Public Offering Price exceeds $10 per Unit, the initial salescharge is the difference between the total sales charge (maximum of1.85% of the Public Offering Price) and the sum of the remainingdeferred sales charge and the creation and development fee. Thedeferred sales charge is fixed at $0.135 per Unit and accrues daily fromApril 10, 2018 through September 9, 2018. Your Portfolio pays aproportionate amount of this charge on the 10th day of each monthbeginning in the accrual period until paid in full. The combination of theinitial and deferred sales charges comprises the “transactional salescharge”. The creation and development fee is fixed at $0.05 per Unitand is paid at the earlier of the end of the initial offering period(anticipated to be three months) or six months following the Initial Dateof Deposit. For more detail, see “Public Offering Price - General.”

The table below compares the hypothetical totalreturn of stocks selected using the Portfol io’sinvestment strategy (the “Hypothetical StrategyStocks”) with the stocks in the Dow Jones U.S.Index. Hypothet ica l tota l return inc ludes anydividends paid on the stocks together with anyincrease or decrease in the value of the stocks. Thetable illustrates a hypothetical investment in theHypothetical Strategy Stocks at the beginning ofeach year -- similar to buying Units of the Portfolio,redeeming them after one year and reinvesting theproceeds in a new portfolio each year.

These hypothetical returns are not actual pastperformance of the Portfolio or prior series but do reflectthe sales charge or expenses you will pay. Of course,

these hypothetical returns are not guarantees of futureresults and the value of your Units will fluctuate. Due tothe application of the relevant screens described under“Portfolio Strategies”, small and mid-cap stocks are oftenmore highly represented in the Hypothetical StrategyStocks than in the Dow Jones U.S. Index, which incertain years, may result in significant differences inrelative hypothetical total returns. You should note thatthe returns shown below are hypothetical annual returnsbased on a calendar year investment. The performanceof the Portfolio may differ because the Portfolio has a 15month life that is not based on a calendar yearinvestment cycle. For more information about thehypothetical total return calculations, see “Notes toHypothetical Performance Tables”.

Notes to Hypothetical Performance Tables

The hypothetical strategy stocks for each applicable time period in a table were identified by applying therespective Portfolio strategy on the last trading day of the prior period on the principal trading exchange. It should benoted that the stocks in the tables are not the same stocks from year to year and may not be the same stocks asthose included in your Portfolio. Hypothetical total return for each period was calculated by (1) subtracting theclosing sale price of the stocks on the last trading day of the prior period from the closing sale price of the stocks onthe last trading day of the period, (2) adding dividends paid during that period and (3) dividing the result by theclosing sale price of the stocks on the last trading day of the prior period and reducing this amount by typical annualPortfolio operating expenses and sales charges. Average annual total return reflects annualized change while totalreturn reflects aggregate change and is not annualized. The sales charge used for the hypothetical total returns atthe beginning of each period is 1.85%. Adjustments were made to reflect events such as stock splits and corporatespinoffs. Hypothetical total return does not take into consideration commissions or taxes that will be incurred byUnitholders. With respect to foreign securities, all values are converted into U.S. dollars using the applicable currencyexchange rate.

The tables represent hypothetical past performance of the related Portfolio strategies (not the Portfolios) and arenot guarantees or indications of future performance of any Portfolio. The hypothetical performance is the retroactiveapplication of a strategy designed with the full benefit of hindsight. Unitholders will not necessarily realize as high atotal return as the hypothetical returns in the tables for several reasons including, among others: the total returnfigures in the tables do not reflect commissions paid by a Portfolio on the purchase of Securities or taxes incurred byUnitholders; the Portfolios are established at different times of the year; a Portfolio may not be able to invest equallyin the Securities according to the strategy weightings and may not be fully invested at all times; a Portfolio may besubject to specific investment exclusions or restrictions; the Securities are often purchased or sold at prices differentfrom the closing prices used in buying and selling Units; the stock prices on a strategy’s implementation date may bedifferent from prices on the Initial Date of Deposit; extraordinary market events that are not expected to be repeatedand may have affected performance; and currency exchange rates will be different. In addition, both stock prices(which may appreciate or depreciate) and dividends (which may be increased, reduced or eliminated) will affectactual returns. There can be no assurance that your Portfolio will outperform its comparison stock index(es) over itslife or future rollover periods, if available. The Sponsor uses data furnished by Bloomberg L.P., Horizon InvestmentServices, FactSet, Capital IQ and Dow Jones Indexes, a CME Group company, to implement the strategies and togenerate the information contained in the tables. These data sources are applied in a consistent manner without theuse of discretion. The Sponsor has not independently verified the data obtained from these sources but has noreason to believe that this data is incorrect in any material respect.

The Dow Jones U.S. Index and its related indexes are unmanaged, are not subject to fees and are not availablefor direct investment.

Notes to Portfolios(1) The Securities are initially represented by “regular way” contracts for the performance of which an irrevocable letter of

credit has been deposited with the Trustee. Contracts to acquire Securities were entered into on December 6, 2017 andhave a settlement date of December 8, 2017 (see “The Portfolios”).

(2) The value of each Security is determined on the bases set forth under “Public Offering--Unit Price” as of the close of the New York Stock Exchange on the business day before the Initial Date of Deposit. In accordance with FASBAccounting Standards Codification (“ASC”), ASC 820, Fair Value Measurements and Disclosures, the Portfolio’sinvestments are classified as Level 1, which refers to security prices determined using quoted prices in active marketsfor identical securities. Other information regarding the Securities, as of the Initial Date of Deposit, is as follows:

“+” indicates that the stock was issued by a foreign company.

(3) Current Dividend Yield for each Security is based on the estimated annual dividends per share and the Security’s valueas of the most recent close of trading on the New York Stock Exchange on the business day before the Initial Date ofDeposit. Generally, estimated annual dividends per share are calculated by annualizing the most recently declaredregular dividends or by adding the most recent regular interim and final dividends declared and reflect any foreignwithholding taxes. In certain cases, this calculation may consider several recently declared dividends in order for theCurrent Dividend Yield to be more reflective of recent historical dividend rates.

(1) The value of the Securities is determined by the Trustee on the bases set forth under “Public Offering--Unit Price”. The contracts to purchaseSecurities are collateralized by separate irrevocable letters of credit which have been deposited with the Trustee.

(2) A portion of the Public Offering Price represents an amount sufficient to pay for all or a portion of the costs incurred in establishing a Portfolio.The amount of these costs are set forth in the “Fee Table”. A distribution will be made as of the earlier of the close of the initial offering period(approximately three months) or six months following the Initial Date of Deposit to an account maintained by the Trustee from which theorganization expense obligation of the investors will be satisfied. To the extent that actual organization costs of a Portfolio are greater than theestimated amount, only the estimated organization costs added to the Public Offering Price will be reimbursed to the Sponsor and deductedfrom the assets of the Portfolio.

(3) Represents the amount of mandatory distributions from a Portfolio on the bases set forth under “Public Offering”.(4) The creation and development fee is payable by a Portfolio on behalf of Unitholders out of the assets of the Portfolio as of the close of the

initial offering period. If Units are redeemed prior to the close of the initial public offering period, the fee will not be deducted from the proceeds.(5) The aggregate public offering price and the aggregate sales charge are computed on the bases set forth under “Public Offering”.(6) Assumes the maximum sales charge.

THE PORTFOLIOS

The Portfolios were created under the laws of theState of New York pursuant to a Trust Indenture andTrust Agreement (the “Trust Agreement”), dated thedate of this prospectus (the “Initial Date of Deposit”),among Invesco Capital Markets, Inc. as Sponsor,Invesco Investment Advisers LLC, as Supervisor, andThe Bank of New York Mellon, as Trustee.

The Portfolios offer investors the opportunity topurchase Units representing proportionate interests inportfolios of equity securities which are components ofmajor stock market indexes. Each Portfolio may be anappropriate medium for investors who desire topart icipate in a portfol io of stocks with greaterdiversification than they might be able to acquireindividually and who are seeking to achieve a betterperformance than the related index.

On the Initial Date of Deposit, the Sponsor depositeddelivery statements relating to contracts for thepurchase of the Securities and an irrevocable letter ofcredit in the amount required for these purchases withthe Trustee. In exchange for these contracts the Trusteedelivered to the Sponsor documentation evidencing theownership of Units of the Portfolios. Unless otherwiseterminated as provided in the Trust Agreement, thePortfolios will terminate on the Mandatory TerminationDate and any remaining Securities will be liquidated ordistributed by the Trustee within a reasonable time. Asused in this prospectus the term “Securities” means thesecurities (including contracts to purchase thesesecurities) listed in each “Portfolio” and any additionalsecurities deposited into each Portfolio.

Additional Units of a Portfolio may be issued at anytime by depositing in the Portfolio (i) additional Securities,(ii) contracts to purchase Securities together with cash orirrevocable letters of credit or (iii) cash (or a letter of creditor the equivalent) with instructions to purchase additionalSecurities. As additional Units are issued by a Portfolio,the aggregate value of the Securities will be increasedand the fractional undivided interest represented by eachUnit may be decreased. The Sponsor may continue tomake additional deposits into a Portfolio following theInitial Date of Deposit provided that the additional

deposits will be in amounts which will maintain, as nearlyas practicable, the same percentage relationship amongthe number of shares of each Security in the Portfoliothat existed immediately prior to the subsequent deposit.Investors may experience a dilution of their investmentsand a reduction in their anticipated income because offluctuations in the prices of the Securities between thetime of the deposit and the purchase of the Securitiesand because the Portfolios will pay the associatedbrokerage or acquisition fees. In addition, during the initialoffering of Units it may not be possible to buy a particularSecurity due to regulatory or trading restrictions, orcorporate actions. While such limitations are in effect,additional Units would be created by purchasing each ofthe Securities in your Portfolio that are not subject tothose limitations. This would also result in the dilution ofthe investment in any such Security not purchased andpotential variances in anticipated income. Purchases andsales of Securities by your Portfolio may impact the valueof the Securities. This may especially be the case duringthe initial offering of Units, upon Portfolio termination andin the course of satisfying large Unit redemptions.

Each Unit of your Portfolio initially offered representsan undivided interest in the Portfolio. At the close of theNew York Stock Exchange on the Init ial Date ofDeposit, the number of Units may be adjusted so thatthe Public Offering Price per Unit equals $10. Thenumber of Units, fractional interest of each Unit in yourPortfolio and the estimated distributions per Unit willincrease or decrease to the extent of any adjustment.To the extent that any Units are redeemed to theTrustee or additional Units are issued as a result ofadditional Securities being deposited by the Sponsor,the fractional undivided interest in your Portfoliorepresented by each unredeemed Unit will increase ordecrease accordingly, although the actual interest inyour Portfolio will remain unchanged. Units will remainoutstanding until redeemed upon tender to the Trusteeby Unitholders, which may include the Sponsor, or untilthe termination of the Trust Agreement.

Each Portfolio consists of (a) the Securities (includingcontracts for the purchase thereof) listed under theapplicable “Portfolio” as may continue to be held fromtime to time in the Portfolio, (b) any additional Securities

A-1

A-2

acquired and held by the Portfolio pursuant to theprovisions of the Trust Agreement and (c) any cash heldin the related Income and Capital Accounts. Neither theSponsor nor the Trustee shall be liable in any way forany contract failure in any of the Securities.

OBJECTIVES AND SECURITIES SELECTION

The objective and investment strategy of eachPortfolio is described in the individual Portfolio sections.Each Portfolio was selected by the Sponsor basedupon information provided by Horizon InvestmentServices, LLC, the Portfolio Consultant, using itsQuadrix stock rating system. There is no assurance thata Portfolio will achieve its objective.

The Portfolios offer the potential to achieve betterperformance than the related indexes throughindex-based investment strategies. Certain strategiesmay also offer the potential for less volatility or potentialfor higher dividend income when compared to therelated index. The investment strategies are designed tobe implemented on an annual basis. Investors who holdUnits through Portfolio termination may have investmentresults that differ significantly from a Unit investmentthat is reinvested into a new trust every twelve months.

The Sponsor does not manage the Portfolios. Youshould note that the selection criteria were applied tothe Securities for inclusion in the Portfolios as of theapplicable selection time. After this time, the Securitiesmay no longer meet the selection criteria. Should aSecurity no longer meet the selection criteria, we willgenerally not remove the Security from its Portfolio. Inoffering the Units to the public, neither the Sponsor norany broker-dealers are recommending any of theindividual Securities but rather the entire pool ofSecurities in a Portfolio, taken as a whole, which arerepresented by the Units.

RISK FACTORS

All investments involve risk. This section describes themain risks that can impact the value of the securities inyour Portfolio. You should understand these risks beforeyou invest. If the value of the securities falls, the value ofyour Units will also fall. We cannot guarantee that yourPortfolio will achieve its objective or that your investmentreturn will be positive over any period.

Market Risk. Market risk is the risk that the value ofthe securities in your Portfolio will fluctuate. This couldcause the value of your Units to fall below your originalpurchase price. Market value fluctuates in response tovarious factors. These can include changes in interestrates, inflation, the financial condition of a security’sissuer, perceptions of the issuer, or ratings on a securityof the issuer. Even though your Portfolio is supervised,

you should remember that we do not manage yourPortfolio. Your Portfolio will not sell a security solelybecause the market value falls as is possible in amanaged fund.

Dividend Payment Risk. Dividend payment risk isthe risk that an issuer of a security is unwilling or unableto pay dividends on a security. Stocks representownership interests in the issuers and are not obligationsof the issuers. Common stockholders have a right toreceive dividends only after the company has providedfor payment of its creditors, bondholders and preferredstockholders. Common stocks do not assure dividendpayments. Dividends are paid only when declared by anissuer’s board of directors and the amount of anydividend may vary over time. If dividends received by aPortfolio are insufficient to cover expenses, redemptionsor other Portfolio costs, it may be necessary for aPortfolio to sell Securities to cover such expenses,redemptions or other costs. Any such sales may result incapital gains or losses to you. See “Taxation”.

Strategy Correlation. Each Portfolio involves therisk that its performance will not sufficiently correspondwith the hypothetical performance of the Portfolio’sinvestment strategy. This can happen for reasons such as:

• the impracticability of owning each of thestrategy stocks with the exact weightings ata given time,

• strategy performance is based on acalendar year strategy while the Portfoliosare created at various times during the yearand have 15 month terms,

• a Portfolio may not be fully invested at alltimes, and

• fees and expenses of a Portfolio.

In addition, the stock selection strategy of a Portfoliomay not be successful in identifying stocks thatappreciate in value or pay significant dividends. APortfolio may not achieve its objective if this happens.

Industry Risks. Your Portfol io may investsignificantly in certain industries. Any negative impact onthe related industry will have a greater impact on thevalue of Units than on a portfolio diversified over several

A-3

industries. You should understand the risks of theseindustries before you invest.

Basic Materials Issuers. The Enhanced SectorStrategy, Sector Rotation Portfolio invests significantly incompanies in the materials sector. Companies in thematerials sector could be adversely affected bycommodity price volatility, exchange rates, importcontrols and increased competition. Production ofmaterials often exceeds demand as a result ofoverbuilding or economic downturns, leading to poorinvestment returns. Companies in the materials sectorare at risk for environmental damage and product liabilityclaims. Companies in the materials sector may beadversely affected by depletion of resources, technicalprogress, labor relations, and governmental regulations.

Consumer Goods and Consumer Staples Issuers.The Dow Jones Total Market Portfolio, Enhanced IndexStrategy Portfolio invests significantly in companies thatmanufacture or sell various consumer products.General risks of these companies include the overallstate of the economy, intense competit ion andconsumer spending trends. A decline in the economywhich results in a reduction of consumers’ disposableincome can negatively impact spending habits. Globalfactors including political developments, imposition ofimport controls, fluctuations in oil prices, and changesin exchange rates may adversely affect issuers ofconsumer products and services.

Competitiveness in the retail industry may requirelarge capital outlays for the installation of automatedcheckout equipment to control inventory, track the saleof items and gauge the success of sales campaigns.Retailers who sell their products over the Internet havethe potential to access more consumers, but mayrequire sophisticated technology to remain competitive.Changes in demographics and consumer tastes canalso affect the demand for, and the success of,consumer products and services in the marketplace.Consumer goods and services companies may besubject to government regulation affecting theirproducts and operations which may negatively impactperformance. Tobacco companies may be adverselyaffected by new laws, regulations and litigation.

Financial Services Issuers. Your Portfolio investssignificantly in banks and other financial servicescompanies. Companies in the financial services industryinclude, but are not limited to, companies involved inactivities such as banking, mortgage finance, consumerfinance, specialized finance, industrial finance andleasing, investment banking and brokerage, assetmanagement and custody, corporate lending,insurance, and financial investment and real estate,including real estate investment trusts. In general,financial services issuers are substantially affected bychanges in economic and market conditions, including:the liquidity and volatility levels in the global financialmarkets; interest rates, as well as currency andcommodities prices; investor sentiment; the rate ofcorporate and consumer defaults; inf lat ion andunemployment; the availability and cost of capital andcredit; exposure to various geographic markets or incommercial and residential real estate; competition fromnew entrants in their fields of business; extensivegovernment regulation; and the overall health of theU.S. and international economies.

The financial services sector was adversely affectedby global developments stemming from the financialcrisis including recessionary conditions, deterioration inthe credit markets and recurring concerns oversovereign debt. A substantial amount of assets werewritten down by financial institutions, with the impact ofthese losses forcing a number of large traditional banks,investment banks, broker-dealers and insurers intoliquidation, combination or other restructuring. This alsosignificantly increased the credit risk, and possibility ofdefault, of bonds issued by such institutions faced withthese problems. In addition, the liquidity of certain debtinstruments has been reduced or eliminated due to thelack of available market makers. While the U.S. andforeign governments, and their respective governmentagencies, have taken steps to address problems in thefinancial markets and with financial institutions, therecan be no assurance that the risks associated withinvestment in financial services issuers will decrease asa result of these steps.

Most financial services companies are subject toextensive governmental regulation, which limits their

activities and may affect their ability to earn a profit froma given line of business. Challenging economic andpolitical conditions, along with increased public scrutinyduring the past several years, have led to newlegislation and increased regulation in the U.S. andabroad, creating additional difficulties for financialinstitutions. Regulatory initiatives and requirements thatare being proposed around the world may beinconsistent or may conflict with regulations to whichfinancial services issuers are currently subject, therebyresulting in higher compliance and legal costs, as wellas the potential for higher operational, capital andliquidity costs. Proposed or enacted regulations mayfurther limit the amounts and types of loans and otherfinancial commitments certain financial services issuerscan make, and further, may limit the interest rates andfees they can charge, the prices they can charge andthe amount of capital they must maintain. These lawsand regulations may affect the manner in which aparticular financial institution does business and theproducts and services it may provide. Increasedregulation may restrict a company’s ability to competein its current businesses or to enter into or acquire newbusinesses. New regulations may reduce or limit acompany’s revenue or impose additional fees, limit thescope of their activities, increase assessments or taxeson those companies and intensify regulatorysupervision, adversely affecting business operations orleading to other negative consequences.

Among the most prominent pieces of legislationfollowing the financial crisis has been the Dodd-FrankWall Street Reform and Consumer Protection Act (the“Dodd-Frank Act”), enacted into federal law on July 21,2010. The Dodd-Frank Act includes reforms andrefinements to modernize existing laws to addressemerging risks and issues in the nation’s evolvingfinancial system. It also establishes entirely newregulatory regimes, including in areas such as systemicrisk regulation, over-the-counter derivatives marketoversight, and federal consumer protection. The Dodd-Frank Act is intended to cover virtually all participants inthe financial services industry for years to come,including banks, thrifts, depository institution holdingcompanies, mortgage lenders, insurance companies,

industrial loan companies, broker-dealers and othersecurities and investment advisory firms, private equityand hedge funds, consumers, numerous federalagencies and the federal regulatory structure. Inparticular, certain provisions of the Dodd-Frank Actincrease the capital requirements of certain financialservices companies supervised by the Federal Reserve,resulting in such companies incurring generally higherdeposit premiums. These types of regulatory changesmay have adverse effects on certain issuers in yourPortfolio, and could lead to decreases in such issuers’profits or revenues. In many cases the full impact of theDodd-Frank Act on a financial institution’s businessremains uncertain because of the extensive rule-makingstill to be completed. The Sponsor is unable to predictthe ultimate impact of the Dodd-Frank Act, and anyresulting regulation, on the securities in your Portfolio oron the financial services industry in general.

Financial services companies in foreign countries arealso subject to regulatory and interest rate concerns. Inparticular, government regulation in certain foreigncountries may include controls on interest rates, creditavailability, prices and currency transfers. The departureof any European Union (“EU”) member from use of theEuro could lead to serious disruptions to foreignexchanges, operations and settlements, which may havean adverse effect on financial services issuers. Morerecently, there is uncertainty regarding the state of the EUfollowing the United Kingdom’s (“U.K.”) initiation onMarch 27, 2017, of the process to exit from the EU(“Brexit”). One of the key global concerns that maycontinue to provide uncertainty in the markets is that theU.K. could be just the first of more EU countries to leavethe union. The effect that Brexit may have on the globalfinancial markets or on the financial services companiesin your Portfolio is uncertain.

The financial condition of customers, clients andcounterparties, including other financial institutions,could adversely affect financial services issuers.Financial services issuers are interrelated as a result ofmarket making, trading, clearing or other counterpartyrelationships. Many of these transactions exposefinancial services issuers to credit risk as a result of theactions of, or deterioration in, the commercial

A-5

soundness of other counterparty financial institutions.Economic and market conditions may increase creditexposures due to the increased risk of customer, clientor counterparty default. Downgrades to the creditratings of financial services issuers could have anegative effect on liquidity, cash flows, competitiveposition, financial condition and results of operations bysignificantly l imiting access to funding or capitalmarkets, increasing borrowing costs or triggeringincreased collateral requirements. Financial servicesissuers face significant legal risk, both from regulatoryinvestigations and proceedings, as well as privateactions. Profit margins of these companies continue toshrink due to the commoditization of tradit ionalbusinesses, new competitors, capital expenditures onnew technology and the pressure to compete globally.

Banks face competition from nontraditional lendingsources as regulatory changes have permitted newentrants to offer various financial products. Technologicaladvances allow these nontraditional lending sources tocut overhead and permit the more efficient use ofcustomer data. Banks continue to face tremendouspressure from mutual funds, brokerage firms and otherfinancial service providers in the competition to furnishservices that were traditionally offered by banks. Bankprofitability is largely dependent on the availability andcost of capital funds, and may fluctuate significantlywhen interest rates change or due to increasedcompetition. Further, economic conditions in the realestate market may have a particularly strong effect oncertain banks and savings associations. Declining realestate values could adversely affect financial institutionsengaged in mortgage finance or other lending orinvesting activities directly or indirectly connected to thevalue of real estate.

Companies engaged in investment management andbroker-dealer activities are subject to volatility in theirearnings and share prices that often exceed thevolatility of the equity market in general. Adversechanges in the direction of the stock market, investorconfidence, equity transaction volume, the level anddirection of interest rates and the outlook of emergingmarkets could adversely affect the financial stability, aswell as the stock prices, of these companies.

Companies involved in the insurance, reinsuranceand risk management industry underwrite, sell ordistribute property, casualty and business insurance.Many factors affect insurance, reinsurance and riskmanagement company profits, including interest ratemovements, the imposition of premium rate caps, amisapprehension of the r isks involved in givenunderwritings, competition and pressure to competeglobally, terrorism, weather catastrophes or otherdisasters and the effects of client mergers. Individualcompanies may be exposed to risks including reserveinadequacy and the inability to collect from reinsurancecarriers. Life and health insurance companies may beaffected by mortality and morbidity rates, including theeffect of epidemics. Insurance companies are subjectto extensive governmental regulation, including theimposition of maximum rate levels, which may not beadequate for some l ines of business. Insurancecompanies may be subject to severe price competition.Proposed or potential tax law changes may alsoadversely affect insurance companies’ policy sales, taxobligations and profitability.

Industrials Issuers. The Enhanced Sector Strategy,Sector Rotation Portfol io invests signif icantly inindustrials companies. General risks of industrialscompanies include the general state of the economy,intense competition, imposition of import controls,volatility in commodity prices, currency exchange ratefluctuation, consolidation, labor relations, domestic andinternational politics, excess capacity and consumerspending trends. Companies in the industrials sectormay be adversely affected by liability for environmentaldamage and product liability claims. Capital goodscompanies may also be significantly affected by overallcapital spending and leverage levels, economic cycles,technical obsolescence, delays in modernization,limitations on supply of key materials, depletion ofresources, government regulations, governmentcontracts and e-commerce initiatives.

Industrials companies may also be affected by factorsmore specific to their individual industries. Industrialmachinery manufacturers may be subject to declines incommercial and consumer demand and the need formodernization. Aerospace and defense companies may

A-6

be influenced by decreased demand for new equipment,aircraft order cancellations, disputes over or ability toobtain or retain government contracts, changes ingovernment budget priorities, changes in aircraft-leasingcontracts and cutbacks in profitable business travel. Thenumber of housing starts, levels of public and non-residential construction including weakening demand fornew office and retail space, and overall constructionspending may adversely affect construction materialsand equipment manufacturers. Stocks of transportationcompanies are cyclical and can be significantly affectedby economic changes, fuel prices and insurance costs.Transportation companies in certain countries may alsobe subject to significant government regulation andoversight, which may negatively impact their businesses.

Technology Issuers. The Dow Jones Total MarketPortfolio, Enhanced Index Strategy Portfolio investssignificantly in technology issuers, which includesinformation technology companies. These companiesinclude companies that are involved in computer andbusiness services, enterprise software/technical software,Internet and computer software, Internet-related services,networking and telecommunications equipment,telecommunications services, electronics products,server hardware, computer hardware and peripherals,semiconductor capital equipment and semiconductors.These companies face risks related to rapidly changingtechnology, rapid product obsolescence, cyclical marketpatterns, evolving industry standards and frequent newproduct introductions.

Companies in this sector face risks from rapid changesin technology, competition, dependence on certainsuppliers and supplies, rapid obsolescence of products orservices, patent termination, frequent new products andgovernment regulation. These companies can also beadversely affected by interruption or reduction in supply ofcomponents or loss of key customers and failure tocomply with certain industry standards.

An unexpected change in technology can have asignificant negative impact on a company. The failure of acompany to introduce new products or technologies orkeep pace with rapidly changing technology can have anegative impact on the company’s results. Informationtechnology companies may also be smaller and/or less

experienced companies with limited product lines,markets or resources. Stocks of some Internetcompanies have high price-to-earnings ratios with little orno earnings histories. Information technology stocks tendto experience substantial price volatility and speculativetrading. Announcements about new products,technologies, operating results or marketing alliances cancause stock prices to fluctuate dramatically. At times,however, extreme price and volume fluctuations areunrelated to the operating performance of a company.This can impact your ability to redeem your Units at aprice equal to or greater than what you paid.

Smaller Capitalization Companies. Your Portfolioinvests in stocks of small capitalization and midcapitalization (collectively “smaller cap”) companies, whichmay involve greater risk than investing in stocks of largercapitalization companies, since they can be subject tomore abrupt or erratic price movements. Many smallercap companies will have had their securities publiclytraded, if at all, for only a short period of time and will nothave had the opportunity to establish a reliable tradingpattern through economic cycles. The price volatility ofsmaller cap companies is relatively higher than larger,older and more mature companies. This greater pricevolatility of smaller cap companies may result from the factthat there may be less market liquidity, less informationpublicly available or fewer investors who monitor theactivities of these companies. In addition, the marketprices of these securities may exhibit more sensitivity tochanges in industry or general economic conditions.Some smaller cap companies will not have been inexistence long enough to experience economic cycles orto demonstrate whether they are sufficiently well managedto survive downturns or inflationary periods. Further, avariety of factors may affect the success of a company'sbusiness beyond the ability of its management to prepareor compensate for them, including domestic andinternational political developments, government tradeand fiscal policies, patterns of trade and war or othermilitary conflict which may affect industries or markets orthe economy generally.

Legislation/Litigation. From time to time, variouslegislative initiatives are proposed in the United Statesand abroad which may have a negative impact on

A-7

certain of the companies represented in your Portfolio,or on the tax treatment of your Portfolio or of yourinvestment in a Portfolio. In addition, litigation regardingany of the issuers of the Securities or of the industriesrepresented by these issuers may negatively impact theshare prices of these Securities. No one can predictwhat impact any pending or threatened litigation willhave on the share prices of the Securities.

Liquidity Risk. Liquidity risk is the risk that the valueof a security will fall if trading in the security is limited orabsent. The market for certain investments may becomeless liquid or illiquid due to adverse changes in theconditions of a particular issuer or due to adversemarket or economic conditions. In the absence of aliquid trading market for a particular security, the price atwhich such security may be sold to meet redemptions,as well as the value of the Units of your Trust, may beadversely affected. No one can guarantee that a liquidtrading market will exist for any security.

No FDIC Guarantee. An investment in your Portfoliois not a deposit of any bank and is not insured orguaranteed by the Federal Deposit InsuranceCorporation or any other government agency.

PUBLIC OFFERING

General. Units are offered at the Public OfferingPrice which consists of the net asset value per Unit plusorganization costs plus the sales charge. The net assetvalue per Unit is the value of the securities, cash andother assets in your Portfolio reduced by the liabilities ofthe Portfolio divided by the total Units outstanding. Themaximum sales charge equals 1.85% of the PublicOffering Price per Unit (1.885% of the aggregateoffering price of the Securities) at the time of purchase.

The initial sales charge is the difference between thetotal sales charge amount (maximum of 1.85% of thePublic Offering Price per Unit) and the sum of theremaining fixed dollar deferred sales charge and thefixed dollar creation and development fee (initially $0.185per Unit). Depending on the Public Offering Price perUnit, you pay the initial sales charge at the time you buyUnits. The deferred sales charge is fixed at $0.135 perUnit. Your Portfolio pays the deferred sales charge in

installments as described in the “Fee Table.” If anydeferred sales charge payment date is not a businessday, we will charge the payment on the next businessday. If you purchase Units after the initial deferred salescharge payment, you will only pay that portion of thepayments not yet collected. If you redeem or sell yourUnits prior to collection of the total deferred salescharge, you will pay any remaining deferred sales chargeupon redemption or sale of your Units. The initial anddeferred sales charges are referred to as the“transactional sales charge.” The transactional salescharge does not include the creation and developmentfee which compensates the Sponsor for creating anddeveloping your Portfolio and is described under“Expenses.” The creation and development fee is fixedat $0.05 per Unit. Your Portfolio pays the creation anddevelopment fee as of the close of the initial offeringperiod as described in the “Fee Table.” If you redeem orsell your Units prior to collection of the creation anddevelopment fee, you will not pay the creation anddevelopment fee upon redemption or sale of your Units.After the initial offering period the maximum sales chargewill be reduced by 0.50%, reflecting the previouscollection of the creation and development fee. Becausethe deferred sales charge and creation and developmentfee are fixed dollar amounts per Unit, the actual chargeswill exceed the percentages shown in the “Fee Table” ifthe Public Offering Price per Unit falls below $10 and willbe less than the percentages shown in the “Fee Table” ifthe Public Offering Price per Unit exceeds $10. In noevent will the maximum total sales charge exceed1.85% of the Public Offering Price per Unit.

The “Fee Table” shows the sales charge calculationat a $10 Public Offering Price per Unit. At a $10Public Offering Price, there is no initial sales chargeduring the initial offering period. If the Public OfferingPrice exceeds $10 per Unit, you will pay an initialsales charge equal to the difference between the totalsales charge and the sum of the remaining deferredsales charge and the creation and development fee.For example, if the Public Offering Price per Unit roseto $14, the maximum sales charge would be $0.259(1.85% of the Publ ic Offer ing Pr ice per Uni t ) ,consisting of an initial sales charge of $0.074, a

A-8

deferred sales charge of $0.135 and the creation anddevelopment fee of $0.050. Since the deferred salescharge and creation and development fee are fixeddollar amounts per Unit, your Portfolio must chargethese amounts per Unit regardless of any decrease innet asset value. However, if the Public Offering Priceper Unit falls to the extent that the maximum salescharge percentage results in a dollar amount that isless than the combined fixed dollar amounts of thedeferred sales charge and creation and developmentfee, your initial sales charge will be a credit equal tothe amount by which these fixed dollar chargesexceed your sales charge at the time you buy Units.In such a situation, the value of securities per Unitwould exceed the Public Offering Price per Unit bythe amount of the initial sales charge credit and thevalue of those securities will fluctuate, which couldresult in a benefit or detriment to Unitholders thatpurchase Units at that price. The initial sales chargecredit is paid by the Sponsor and is not paid by yourPortfolio. If the Public Offering Price per Unit fell to $6,the maximum sales charge would be $0.111 (1.85%of the Public Offering Price per Unit), which consistsof an initial sales charge (credit) of -$0.074, a deferredsales charge of $0.135 and a creat ion anddevelopment fee of $0.050.

The actual sales charge that may be paid by aninvestor may differ slightly from the sales chargesshown herein due to rounding that occurs in thecalculation of the Public Offering Price and in thenumber of Units purchased.

The minimum purchase is 100 Units (25 Units forretirement accounts) but may vary by selling firm.Certain broker-dealers or selling firms may charge anorder handling fee for processing Unit purchases.

Reducing Your Sales Charge. The Sponsoroffers ways for you to reduce the sales charge that youpay. It is your financial professional’s responsibility toalert the Sponsor of any discount when you purchaseUnits. Before you purchase Units you must also informyour financial professional of your qualification for anydiscount to be eligible for a reduced sales charge. Sincethe deferred sales charge and creation anddevelopment fee are fixed dollar amounts per Unit, your

Portfol io must charge these amounts per Unitregardless of any discounts. However, if you are eligibleto receive a discount such that your total sales chargeis less than the fixed dollar amounts of the deferredsales charge and creation and development fee, you willreceive a credit equal to the difference between yourtotal sales charge and these fixed dollar charges at thetime you buy Units.

Fee Accounts. Investors may purchase Units throughregistered investment advisers, certified financial plannersand registered broker-dealers who in each case eithercharge periodic fees for brokerage services, financialplanning, investment advisory or asset managementservices, or provide such services in connection with theestablishment of an investment account for which acomprehensive “wrap fee” charge (“Wrap Fee”) isimposed (“Fee Accounts”). If Units of a Portfolio arepurchased for a Fee Account and the Portfolio is subjectto a Wrap Fee (i.e., the Portfolio is “Wrap Fee Eligible”),then the purchase will not be subject to the transactionalsales charge but will be subject to the creation anddevelopment fee of $0.05 per Unit that is retained by theSponsor. Please refer to the section called “Fee Accounts”for additional information on these purchases. TheSponsor reserves the right to limit or deny purchases ofUnits described in this paragraph by investors or sellingfirms whose frequent trading activity is determined to bedetrimental to a Portfolio. Wrap Fee Eligible Units are noteligible for any sales charge discounts in addition to thatwhich is described in this paragraph and under the “FeeAccounts” section found below.

Employees. Employees, officers and directors(including their spouses (or the equivalent if recognizedunder local law) and children or step-children under 21living in the same household, parents or step-parentsand trustees, custodians or fiduciaries for the benefit ofsuch persons) of Invesco Capital Markets, Inc. and itsaffiliates, and dealers and their affiliates may purchaseUnits at the Public Offering Price less the applicabledealer concession. All employee discounts are subjectto the pol icies of the related sel l ing f irm. Onlyemployees, officers and directors of companies thatallow their employees to participate in this employeediscount program are eligible for the discounts.

A-9

Distribution Reinvestments. We do not charge anysales charge when you reinvest distributions from yourPortfolio into additional Units of your Portfolio. Since thedeferred sales charge and creation and development feeare fixed dollar amounts per Unit, your Portfolio mustcharge these amounts per Unit regardless of thisdiscount. If you elect to reinvest distributions, the Sponsorwill credit you with additional Units with a dollar valuesufficient to cover the amount of any remaining deferredsales charge and creation and development fee that willbe collected on such Units at the time of reinvestment.The dollar value of these Units will fluctuate over time.

Unit Price. The Public Offering Price of Units will varyfrom the amounts stated under “Essential Information” inaccordance with fluctuations in the prices of theunderlying Securities in the Portfolios. The initial price ofthe Securities upon deposit by the Sponsor wasdetermined by the Trustee. The Trustee will generallydetermine the value of the Securities as of the EvaluationTime on each business day and will adjust the PublicOffering Price of Units accordingly. The Evaluation Time isthe close of the New York Stock Exchange on eachbusiness day. The term “business day”, as used hereinand under “Rights of Unitholders--Redemption of Units”,means any day on which the New York Stock Exchangeis open for regular trading. The Public Offering Price perUnit will be effective for all orders received prior to theEvaluation Time on each business day. Orders receivedby the Sponsor prior to the Evaluation Time and ordersreceived by authorized financial professionals prior to theEvaluation Time that are properly transmitted to theSponsor by the time designated by the Sponsor, arepriced based on the date of receipt. Orders received bythe Sponsor after the Evaluation Time, and ordersreceived by authorized financial professionals after theEvaluation Time or orders received by such persons thatare not transmitted to the Sponsor until after the timedesignated by the Sponsor, are priced based on the dateof the next determined Public Offering Price per Unitprovided they are received timely by the Sponsor on suchdate. It is the responsibility of authorized financialprofessionals to transmit orders received by them to theSponsor so they will be received in a timely manner.

The value of portfolio securities is based on thesecurities’ market price when available. When a marketprice is not readily available, including circumstancesunder which the Trustee determines that a security’smarket price is not accurate, a portfolio security is valuedat its fair value, as determined under proceduresestablished by the Trustee or an independent pricingservice used by the Trustee. In these cases, a Portfolio’snet asset value will reflect certain portfolio securities’ fairvalue rather than their market price. With respect tosecurities that are primarily listed on foreign exchanges,the value of the portfolio securities may change on dayswhen you will not be able to purchase or sell Units. Thevalue of any foreign securities is based on the applicablecurrency exchange rate as of the Evaluation Time. TheSponsor will provide price dissemination and oversightservices to the Portfolios.

During the initial offering period, part of the PublicOffering Price represents an amount that will pay thecosts incurred in establishing your Portfolio. Thesecosts include the costs of preparing documents relatingto your Portfolio (such as the registration statement,prospectus, trust agreement and legal documents),federal and state registration fees, the initial fees andexpenses of the Trustee and the initial audit. YourPortfolio will sell securities to reimburse us for thesecosts at the end of the initial offering period or after sixmonths, if earlier. The value of your Units will declinewhen your Portfolio pays these costs.

Unit Distribution. Units will be distributed to thepublic by the Sponsor, broker-dealers and others at thePublic Offer ing Price. Units repurchased in thesecondary market, if any, may be offered by thisprospectus at the secondary market Public OfferingPrice in the manner described above.

Unit Sales Concessions. Brokers, dealers and otherswill be allowed a regular concession or agencycommission in connection with the distribution of Unitsduring the initial offering period of 1.25% of the PublicOffering Price per Unit.

The Sponsor may discontinuepurchases of Units or discontinue purchases at this priceat any time. In the event that a secondary market is notmaintained, a Unitholder will be able to dispose of Unitsby tendering them to the Trustee for redemption at theRedemption Price.

To purchase Units in these Fee Accounts, yourfinancial professional must purchase Units designatedwith one of the Wrap Fee CUSIP numbers set forth under“Essential Information,” either Wrap Fee Cash for cashdistributions or Wrap Fee Reinvest for the reinvestment ofdistributions in additional Units, if available. See “Rights ofUnitholders--Reinvestment Option.”

RIGHTS OF UNITHOLDERS

Distributions. Dividends and interest, net ofexpenses, and any net proceeds from the sale ofSecurities received by a Portfolio will generally bedistributed to Unitholders on each Distribution Date toUnitholders of record on the preceding Record Date.These dates appear under “Essential Information”.Distributions made by the securities in your Portfolioinclude ordinary income, but may also include sourcesother than ordinary income such as returns of capital,loan proceeds, short-term capital gains and long-termcapital gains (see “Taxation--Distributions”). In addition,the Portfolios will generally make required distributionsat the end of each year because each is structured as a“regulated investment company” for federal taxpurposes. Unitholders wi l l also receive a f inaldistribution of income when their Portfolio terminates. Aperson becomes a Unitholder of record on the date ofsettlement (generally two business days after Units areordered, or any shorter period as may be required bythe applicable rules under the 1934 Act). Unitholdersmay elect to receive distributions in cash or to havedistributions reinvested into additional Units. See“Rights of Unitholders--Reinvestment Option”.

Dividends and interest received by a Portfolio arecredited to the Income Account of the Portfolio. Otherreceipts (e.g., capital gains, proceeds from the sale ofSecurities, etc.) are credited to the Capital Account.Proceeds received on the sale of any Securities, to theextent not used to meet redemptions of Units or paydeferred sales charges, fees or expenses, will bedistributed to Unitholders. Proceeds received from thedisposition of any Securities after a Record Date andprior to the following Distribution Date will be held in

the Capital Account and not distributed until the nextDistribution Date. Any distribution to Unitholdersconsists of each Unitholder’s pro rata share of theavailable cash in the Income and Capital Accounts asof the related Record Date.

Estimated Distributions. The estimated initialdistribution and estimated net annual income per Unitmay be shown under “Essential Information.” Generally,the estimate of the income a Portfolio may receive isbased on the most recent ordinary quarterly dividendsdeclared by an issuer, the most recent interim and finaldividends declared for certain foreign issuers, orscheduled income payments (in all cases accounting forany applicable foreign withholding taxes). In certain cases,estimated net annual income may also be based uponseveral recently declared dividends of an issuer. However,common stocks do not assure dividend payments andtherefore the amount of future dividend income to yourPortfolio is uncertain. The actual net annual distributionsmay decrease over time because a portion of theSecurities included in a Portfolio will be sold to pay for theorganization costs, deferred sales charge and creationand development fee. Securities may also be sold to payregular fees and expenses during a Portfolio’s life.Dividend and income conventions for certain companiesand/or certain countries differ from those typically used inthe United States and in certain instances,dividends/income paid or declared over several years orother periods may be used to estimate annualdistributions. The actual net annual income distributionsyou receive will vary from the estimated amount due tochanges in a Portfolio’s fees and expenses, in actualincome received by a Portfolio, currency fluctuations andwith changes in a Portfolio such as the acquisition, call,maturity or sale of Securities. Due to these and variousother factors, actual income received by a Portfolio willmost likely differ from the most recent dividends orscheduled income payments.

Reinvestment Option. Unitholders may havedistributions automatically reinvested in additional Unitswithout a sales charge (to the extent Units may belawfully offered for sale in the state in which theUnitholder resides). The CUSIP numbers for either “Cash”distributions or “Reinvest” for the reinvestment of

A-13

distributions are set forth under “Essential Information”.Brokers and dealers can use the Dividend ReinvestmentService through Depository Trust Company (“DTC”) orpurchase a Reinvest (or Wrap Fee Reinvest in the case ofWrap Fee Eligible Units held in Fee Accounts) CUSIP, ifavailable. To participate in this reinvestment option, aUnitholder must file with the Trustee a written notice ofelection, together with any other documentation that theTrustee may then require, at least five days prior to therelated Record Date. A Unitholder’s election will apply toall Units owned by the Unitholder and will remain in effectuntil changed by the Unitholder. The reinvestment optionis not offered during the 30 calendar days prior totermination. If Units are unavailable for reinvestment orthis reinvestment option is no longer available,distributions will be paid in cash. Distributions will betaxable to Unitholders if paid in cash or automaticallyreinvested in additional Units. See “Taxation”.

A participant may elect to terminate his or herreinvestment plan and receive future distributions in cashby notifying the Trustee in writing no later than five daysbefore a Distribution Date. The Sponsor shall have theright to suspend or terminate the reinvestment plan atany time. The reinvestment plan is subject to availabilityor limitation by each broker-dealer or selling firm.Broker-dealers may suspend or terminate the offering ofa reinvestment plan at any time. Please contact yourfinancial professional for additional information.

Redemption of Units. All or a portion of your Unitsmay be tendered to The Bank of New York Mellon, theTrustee, for redemption at Unit Investment Trust Division,111 Sanders Creek Parkway, East Syracuse, New York13057, on any day the New York Stock Exchange isopen. No redemption fee will be charged by the Sponsoror the Trustee, but you are responsible for applicablegovernmental charges, if any. Units redeemed by theTrustee will be canceled. You may redeem all or a portionof your Units by sending a request for redemption to yourbank or broker-dealer through which you hold your Units.No later than two business days (or any shorter period asmay be required by the applicable rules under the 1934Act) following satisfactory tender, the Unitholder will beentitled to receive in cash an amount for each Unit equalto the Redemption Price per Unit next computed on the

date of tender. The “date of tender” is deemed to be thedate on which Units are received by the Trustee, exceptthat with respect to Units received by the Trustee afterthe Evaluation Time or on a day which is not a Portfoliobusiness day, the date of tender is deemed to be thenext business day. Redemption requests received by theTrustee after the Evaluation Time, and redemptionrequests received by authorized financial professionalsafter the Evaluation Time or redemption requestsreceived by such persons that are not transmitted to theTrustee until after the time designated by the Trustee, arepriced based on the date of the next determinedredemption price provided they are received timely by theTrustee on such date. It is the responsibility of authorizedfinancial professionals to transmit redemption requestsreceived by them to the Trustee so they will be receivedin a timely manner. Certain broker-dealers or selling firmsmay charge an order handling fee for processingredemption requests. Units redeemed directly throughthe Trustee are not subject to such fees.

Unitholders tendering 1,000 or more Units of thePortfolios (or such higher amount as may be required byyour broker-dealer or selling agent) for redemption mayrequest an in kind distribution of Securities equal to theRedemption Price per Unit on the date of tender.Unitholders may not request an in kind distribution ofSecurities during the initial offering period or within 30calendar days of a Portfolio’s termination. The Portfoliosgenerally will not offer in kind distributions of portfoliosecurities that are held in foreign markets. An in kinddistribution will be made by the Trustee through thedistribution of each of the Securities in book-entry form tothe account of the Unitholder’s broker-dealer at DTC.Amounts representing fractional shares will be distributedin cash. The Trustee may adjust the number of shares ofany Security included in a Unitholder’s in kind distributionto facilitate the distribution of whole shares. The in kinddistribution option may be modified or discontinued at anytime without notice. Notwithstanding the foregoing, if theUnitholder requesting an in kind distribution is theSponsor or an affiliated person of a Portfolio, the Trusteemay make an in kind distribution to such Unitholderprovided that no one with a pecuniary incentive toinfluence the in kind distribution may influence selection of

A-14

the distributed securities, the distribution must consist of apro rata distribution of all portfolio securities (with limitedexceptions) and the in kind distribution may not favor suchaffiliated person to the detriment of any other Unitholder.Unitholders will incur transaction costs in liquidatingsecurities received in an in-kind distribution, and any suchsecurities received will be subject to market risk until sold.In the event that any securities received in-kind are illiquid,Unitholders will bear the risk of not being able to sell suchsecurities in the near term, or at all.

The Trustee may sell Securities to satisfy Unitredemptions. To the extent that Securit ies areredeemed in kind or sold, the size of a Portfolio will be,and the diversity of a Portfolio may be, reduced. Salesmay be required at a time when Securities would nototherwise be sold and may result in lower prices thanmight otherwise be realized. The price received uponredemption may be more or less than the amount paidby the Unitholder depending on the value of theSecurities at the time of redemption. Special federalincome tax consequences will result if a Unitholderrequests an in kind distribution. See “Taxation”.

The Redemption Price per Unit and the secondarymarket repurchase price per Unit are equal to the prorata share of each Unit in each Portfolio determined onthe basis of (i) the cash on hand in the Portfolio, (ii) thevalue of the Securities in the Portfolio and (iii) dividendsor other income distr ibutions receivable on theSecurities in the Portfolio trading ex-dividend as of thedate of computation, less (a) amounts representingtaxes or other governmental charges payable out of thePortfolio, (b) the accrued expenses of the Portfolio(including costs associated with liquidating securitiesafter the end of the initial offering period) and (c) anyunpaid deferred sales charge payments. During theinitial offering period, the redemption price and thesecondary market repurchase price are not reduced bythe estimated organization costs or the creation anddevelopment fee. For these purposes, the Trustee willdetermine the value of the Securities as describedunder “Public Offering--Unit Price”.

The right of redemption may be suspended andpayment postponed for any period during which theNew York Stock Exchange is closed, other than for

customary weekend and holiday closings, or any periodduring which the SEC determines that trading on thatExchange is restricted or an emergency exists, as aresult of which disposal or evaluation of the Securities isnot reasonably practicable, or for other periods as theSEC may permit.

Exchange Option. When you redeem Units of yourPortfolio or when your Portfolio terminates (see “Rollover”below), you may be able to exchange your Units for unitsof other Invesco unit trusts. You should contact yourfinancial professional for more information about trustscurrently available for exchanges. Before you exchangeUnits, you should read the prospectus of the new trustcarefully and understand the risks and fees. You shouldthen discuss this option with your financial professional todetermine whether your investment goals have changed,whether current trusts suit you and to discuss taxconsequences. A rollover or exchange is a taxable eventto you. We may discontinue this option at any time.

Rollover. We may offer a subsequent series of eachPortfolio for a Rollover when the Portfolios terminate.

On the Mandatory Termination Date you will have theoption to (1) participate in a Rollover and have yourUnits reinvested into a subsequent trust series or (2) receive a cash distribution.

If you elect to participate in a cash Rollover, your Unitswill be redeemed on the Mandatory Termination Date. Asthe redemption proceeds become available, the proceeds(including dividends) will be invested in a new trust seriesat the public offering price for the new trust. The Trusteewill attempt to sell Securities to satisfy the redemption asquickly as practicable on the Mandatory Termination Date.We do not anticipate that the sale period will be longerthan one day, however, certain factors could affect theability to sell the Securities and could impact the length ofthe sale period. The liquidity of any Security depends onthe daily trading volume of the Security and the amountavailable for redemption and reinvestment on any day.

We may make subsequent trust series available forsale at various times during the year. Of course, wecannot guarantee that a subsequent trust or sufficientunits will be available or that any subsequent trusts willoffer the same investment strategies or objectives as the

A-15

current Portfolios. We cannot guarantee that a Rolloverwill avoid any negative market price consequencesresulting from trading large volumes of securities. Marketprice trends may make it advantageous to sell or buysecurities more quickly or more slowly than permitted bythe Portfolio procedures. We may, in our sole discretion,modify a Rollover or stop creating units of a trust at anytime regardless of whether all proceeds of Unitholdershave been reinvested in a Rollover. If we decide not tooffer a subsequent series, Unitholders will be notifiedprior to the Mandatory Termination Date. Cash which hasnot been reinvested in a Rollover will be distributed toUnitholders shortly after the Mandatory Termination Date.Rollover participants may receive taxable dividends orrealize taxable capital gains which are reinvested inconnection with a Rollover but may not be entitled to adeduction for capital losses due to the “wash sale” taxrules. Due to the reinvestment in a subsequent trust, nocash will be distributed to pay any taxes. See “Taxation”.

Units. Ownership of Units is evidenced in book-entryform only and will not be evidenced by certificates. Unitspurchased or held through your bank or broker-dealer willbe recorded in book-entry form and credited to theaccount of your bank or broker-dealer at DTC. Units aretransferable by contacting your bank or broker-dealerthrough which you hold your Units. Transfer, and therequirements therefore, wil l be governed by theapplicable procedures of DTC and your agreement withthe DTC participant in whose name your Units areregistered on the transfer records of DTC.

Reports Provided. Unitholders will receive astatement of dividends and other amounts received by aPortfolio for each distribution. Within a reasonable timeafter the end of each year, each person who was aUnitholder during that year will receive a statementdescribing dividends and capital received, actual Portfoliodistributions, Portfolio expenses, a list of the Securitiesand other Portfolio information. Unitholders may obtainevaluations of the Securities upon request to the Trustee.If you have questions regarding your account or yourPortfolio, please contact your financial advisor or theTrustee. The Sponsor does not have access to individualaccount information.

PORTFOLIO ADMINISTRATION

Portfolio Administration. The Portfolios are notmanaged funds and, except as provided in the TrustAgreement, Securities generally will not be sold orreplaced. The Sponsor may, however, direct thatSecurities be sold in certain limited circumstances toprotect a Portfolio based on advice from the Supervisor.These situations may include events such as the issuerhaving defaulted on payment of any of its outstandingobligations or the price of a Security has declined tosuch an extent or other credit factors exist so that in theopinion of the Supervisor retention of the Security wouldbe detrimental to a Portfolio. If a public tender offer hasbeen made for a Security or a merger or acquisition hasbeen announced affecting a Security, the Trustee mayeither sel l the Security or accept an offer i f theSupervisor determines that the sale or exchange is inthe best interest of Unitholders. The Trustee willdistribute any cash proceeds to Unitholders. In addition,the Trustee may sell Securities to redeem Units or payPortfol io expenses or deferred sales charges. Ifsecurities or property are acquired by a Portfolio, theSponsor may direct the Trustee to sell the securities orproperty and distribute the proceeds to Unitholders orto accept the securities or property for deposit in thePortfolio. Should any contract for the purchase of any ofthe Securities fail, the Sponsor will (unless substantiallyall of the moneys held in a Portfolio to cover thepurchase are reinvested in substitute Securities inaccordance with the Trust Agreement) refund the cashand sales charge attributable to the failed contract to allUnitholders on or before the next Distribution Date.

The Sponsor may direct the reinvestment of proceedsof the sale of Securities if the sale is the direct result ofserious adverse credit factors which, in the opinion ofthe Sponsor, would make retention of the Securitiesdetrimental to your Portfolio. In such a case, theSponsor may, but is not obligated to, direct thereinvestment of sale proceeds in any other securitiesthat meet the criteria for inclusion in your Portfolio on theInitial Date of Deposit. The Sponsor may also instruct theTrustee to take action necessary to ensure that yourPortfolio continues to satisfy the qualifications of a

A-16

regulated investment company and to avoid impositionof tax on undistributed income of the Portfolio.

When your Portfolio sells Securities, the compositionand diversity of the Securities in the Portfolio may bealtered. In order to obtain the best price for a Portfolio, itmay be necessary for the Supervisor to specifyminimum amounts (generally 100 shares) in whichblocks of Securit ies are to be sold. In effectingpurchases and sales of Portfolio securities, the Sponsormay direct that orders be placed with and brokeragecommissions be paid to brokers, including brokerswhich may be affiliated with the Portfolios, the Sponsoror dealers participating in the offering of Units.

Pursuant to an exemptive order, your Portfolio maybe permitted to sell Securities to a new trust when itterminates if those Securities are included in the newtrust. The exemption may enable your Portfolio toeliminate commission costs on these transactions. Theprice for those securities will be the closing sale price onthe sale date on the exchange where the Securities areprincipally traded, as certified by the Sponsor.

Amendment of the Trust Agreement. TheTrustee and the Sponsor may amend the TrustAgreement without the consent of Unitholders tocorrect any provision which may be defective or tomake other provisions that will not materially adverselyaffect Unitholders (as determined in good faith by theSponsor and the Trustee). The Trust Agreement maynot be amended to increase the number of Units orpermit acquisit ion of securit ies in addition to orsubstitution for the Securities (except as provided inthe Trust Agreement) . The Trustee wi l l not i fyUnitholders of any amendment.

Termination. Your Portfolio will terminate on theMandatory Termination Date specified under “EssentialInformation” or upon the sale or other disposition of thelast Security held in the Portfolio. Your Portfolio may beterminated at any time with consent of Unitholdersrepresenting two-thirds of the outstanding Units or bythe Trustee when the value of the Portfolio is less than$500,000 ($3,000,000 if the value of the Portfolio hasexceeded $15,000,000) (the “Minimum TerminationValue”). Your Portfolio will be liquidated by the Trustee

in the event that a sufficient number of Units of thePortfolio not yet sold are tendered for redemption bythe Sponsor, so that the net worth of the Portfoliowould be reduced to less than 40% of the value of theSecurities at the time they were deposited in thePortfolio. If your Portfolio is liquidated because of theredemption of unsold Units by the Sponsor, theSponsor will refund to each purchaser of Units theentire sales charge paid by such purchaser. TheTrustee may begin to sell Securities in connection witha Portfolio termination nine business days before, andno later than, the Mandatory Termination Date.Qualified Unitholders may elect an in kind distribution ofSecurities, provided that Unitholders may not requestan in kind distribution of Securities within 30 calendardays of a Portfolio’s termination. Any in kind distributionof Securities will be made in the manner and subject tothe restr ict ions described under “Rights ofUnitholders--Redemption of Units”, provided that, inconnection with an in kind distribution election morethan 30 calendar days prior to termination, Unitholderstendering 1,000 or more Units of a Portfolio (or suchhigher amount as may be required by your broker-dealer or sel l ing agent) may request an in kinddistribution of Securities equal to the Redemption Priceper Unit on the date of tender. Unitholders will receive afinal cash distribution within a reasonable time after theMandatory Termination Date. All distributions will benet of Portfolio expenses and costs. Unitholders willreceive a f inal distr ibut ion statement fol lowingtermination. The Information Supplement containsfurther information regarding termination of yourPortfolio. See “Additional Information”.

TAXATION

This section summarizes some of the principal U.S.federal income tax consequences of owning Units of thePortfolios as of the date of this prospectus. Tax lawsand interpretations are subject to change, possibly withretroactive effect, and this summary does not describeall of the tax consequences to all taxpayers. Forexample, this summary generally does not describeyour situation if you are a corporation, a non-U.S.person, a broker/dealer, a tax-exempt entity, financialinstitution, person who marks to market their Units orother investor with special circumstances. In addition,this section does not describe your alternativeminimum, state, local or foreign tax consequences ofinvesting in a Portfolio.

This federal income tax summary is based in part onthe advice of counsel to the Sponsor. The InternalRevenue Service could disagree with any conclusions

A-18

set forth in this section. In addition, our counsel was notasked to review the federal income tax treatment of theassets to be deposited in your Portfolio.

Additional information related to taxes is contained inthe Information Supplement. As with any investment,you should seek advice based on your individualcircumstances from your own tax advisor.

Portfolio Status. Your Portfolio intends to electand to qualify annually as a “regulated investmentcompany” (“RIC”) under the federal tax laws. If yourPortfolio qualifies under the tax law as a RIC anddistributes its income in the manner and amountsrequired by the RIC tax requirements, the Portfoliogenerally will not pay federal income taxes. But there isno assurance that the distributions made by yourPortfolio will eliminate all taxes for every year at the levelof your Portfolio.

Distributions. Portfolio distributions are generallytaxable to you. After the end of each year, you willreceive a tax statement reporting your Portfolio’sdistributions, including the amounts of ordinary incomedistributions and capital gains dividends. Your Portfoliomay make taxable distributions to you even in periodsduring which the value of your Units has declined.Ordinary income distributions are generally taxed atyour federal tax rate for ordinary income, however, asfurther discussed below, certain ordinary incomedistributions received from your Portfolio may be taxed,under current federal law, at the capital gains tax rates.Certain ordinary income dividends on Units that areattributable to qualifying dividends received by yourPortfolio from certain corporations may be reported bythe Portfolio as being eligible for the dividends receiveddeduction for corporate Unitholders provided certainholding period requirements are met. Income from thePortfolio and gains on the sale of your Units may alsobe subject to a 3.8% federal tax imposed generally onnet investment income if your adjusted gross incomeexceeds certain threshold amounts, which are$250,000 in the case of married couples filing jointreturns and $200,000 in the case of single individuals.In addition, your Portfolio may make distributions thatrepresent a return of capital for tax purposes to theextent of the Unitholder’s basis in the Units, and any

additional amounts in excess of basis would be taxedas a capital gain. Generally, you will treat all capital gainsdividends as long-term capital gains regardless of howlong you have owned your Units. The tax status of yourdistributions from your Portfolio is not affected bywhether you reinvest your distributions in additionalUnits or receive them in cash. The income from yourPortfolio that you must take into account for federalincome tax purposes is not reduced by amounts usedto pay a deferred sales charge, if any. The tax laws mayrequire you to treat certain distributions made to you inJanuary as if you had received them on December 31of the previous year.

A distribution paid by your Portfolio reduces thePortfolio’s net asset value per Unit on the date paid bythe amount of the distribution. Accordingly, a distributionpaid shortly after a purchase of Units by a Unitholderwould represent, in substance, a partial return of capital,however, it would be subject to income taxes.

Sale or Redemption of Units. If you sell orredeem your Units, you will generally recognize a taxablegain or loss. To determine the amount of this gain orloss, you must subtract your adjusted tax basis in yourUnits from the amount you receive in the transaction.Your initial tax basis in your Units is generally equal to thecost of your Units, generally including sales charges. Insome cases, however, you may have to adjust your taxbasis after you purchase your Units.

Capital Gains and Losses and CertainOrdinary Income Dividends. Net capital gainequals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain orloss is long-term if the holding period for the asset ismore than one year and is short-term if the holdingperiod for the asset is one year or less. You mustexclude the date you purchase your Uni ts todetermine your holding period. However, i f youreceive a capital gain dividend from your Portfolio andsell your Units at a loss after holding it for six monthsor less, the loss will be recharacterized as long-termcapital loss to the extent of the capital gain dividendreceived. The tax rates for capital gains realized fromassets held for one year or less are generally thesame as for ordinary income.

A-19

A-20

In certain circumstances, ordinary income dividendsreceived by an individual Unitholder from a regulatedinvestment company such as your Portfolio may be taxedat the same federal rates that apply to net capital gain (asdiscussed above), provided certain holding periodrequirements are satisfied and provided the dividends areattributable to qualified dividend income received by thePortfolio itself. Your Portfolio will provide notice to itsUnitholders of the amount of any distribution which maybe taken into account as qualified dividend income whichis eligible for the capital gains tax rates. There is norequirement that tax consequences be taken into accountin administering your Portfolio.

In Kind Distributions. Under certain circumstances,as described in this prospectus, you may receive an inkind distribution of Portfolio securities when you redeemyour Units. In general, this distribution will be treated as asale for federal income tax purposes and you willrecognize gain or loss, based on the value at that time ofthe securities and the amount of cash received, andsubject to certain limitations on the deductibility of lossesunder the tax rules.

Rollovers and Exchanges. If you elect to have yourproceeds from your Portfolio rolled over into a future trust,it would generally be considered a sale for federal incometax purposes and any gain on the sale will be treated as acapital gain, and, in general, any loss will be treated as acapital loss. However, any loss realized on a sale orexchange will be disallowed to the extent that Unitsdisposed of are replaced (including through reinvestmentof dividends) within a period of 61 days beginning 30 daysbefore and ending 30 days after disposition of Units or tothe extent that the Unitholder, during such period,acquires or enters into an option or contract to acquire,substantially identical stock or securities. In such a case,the basis of the Units acquired will be adjusted to reflectthe disallowed loss.

Deductibility of Portfolio Expenses. Expensesincurred and deducted by your Portfolio will generallynot be treated as income taxable to you. In somecases, however, you may be required to treat yourportion of these Portfolio expenses as income. In thesecases you may be able to take a deduction for theseexpenses. However, certain miscellaneous itemized

deductions, such as investment expenses, may bededucted by individuals only to the extent that all ofthese deductions exceed 2% of the individual’sadjusted gross income. Such deductions may besubject to limitation for taxpayers whose incomeexceeds certain levels.

Foreign Investors. If you are a foreign investor(i.e., an investor other than a U.S. citizen or resident ora U.S. corporation, partnership, estate or trust),generally, subject to applicable tax treaties, distributionsto you from your Portfolio will be characterized asdividends for federal income tax purposes (other thandividends that the Portfolio reports as capital gaindividends) and will be subject to U.S. income taxes,including withholding taxes, subject to certainexceptions described below. You may be eligible undercertain income tax treaties for a reduction in withholdingrates. However distributions received by a foreigninvestor from a Portfolio that are properly reported bythe trust as capital gain dividends may not be subject toU.S. federal income taxes, including withholding taxes,provided that the Portfolio makes certain elections andcertain other conditions are met.

The Foreign Account Tax Compliance Act(“FATCA”). A 30% withholding tax on your Portfolio’sdistributions, including capital gains distributions, andon gross proceeds from the sale or other disposition ofUnits generally applies if paid to a foreign entity unless:(i) if the foreign entity is a “foreign financial institution” asdefined under FATCA, the foreign entity undertakescertain due diligence, reporting, withholding, andcertification obligations, (ii) if the foreign entity is not a“foreign financial institution,” it identifies certain of itsU.S. investors or (iii) the foreign entity is otherwiseexcepted under FATCA. If required under the rulesabove and subject to the appl icabi l i ty of anyintergovernmental agreements between the UnitedStates and the relevant foreign country, withholdingunder FATCA applies: (i) with respect to distributionsfrom your Portfolio and (ii) with respect to certain capitalgains distributions and gross proceeds from a sale ordisposition of Units that occur on or after January 1,2019. If withholding is required under FATCA on apayment related to your Units, investors that otherwise

A-21

would not be subject to withholding (or that otherwisewould be entitled to a reduced rate of withholding) onsuch payment generally will be required to seek arefund or credit from the IRS to obtain the benefit ofsuch exemption or reduction. Your Portfolio will not payany additional amounts in respect of amounts withheldunder FATCA. You should consult your tax advisorregarding the effect of FATCA based on your individualcircumstances.

Foreign Tax Credit. If your Portfolio invests in anyforeign securities, the tax statement that you receivemay include an item showing foreign taxes yourPortfolio paid to other countries. In this case, dividendstaxed to you will include your share of the taxes yourPortfolio paid to other countries. You may be able todeduct or receive a tax credit for your share of thesetaxes if your Portfolio meets certain requirements forpassing through such deductions or credits to you.

Backup Withholding. By law, your Portfolio mustwithhold as backup withholding a percentage (currently28%) of your taxable distributions and redemptionproceeds if you do not provide your correct socialsecurity or taxpayer identification number and certifythat you are not subject to backup withholding, or if theIRS instructs your Portfolio to do so.

Investors should consult their tax advisorsconcerning the federal, state, local and foreign taxconsequences of investing in the Portfolio.

PORTFOLIO OPERATING EXPENSES

General. The fees and expenses of your Portfolio willgenerally accrue on a daily basis. Portfolio operating feesand expenses are generally paid out of the IncomeAccount to the extent funds are available, and then fromthe Capital Account. The deferred sales charge, creationand development fee and organization costs aregenerally paid out of the Capital Account of yourPortfolio. It is expected that Securities will be sold to paythese amounts which will result in capital gains or lossesto Unitholders. See “Taxation”. These sales will reducefuture income distributions. The Sponsor’s, Supervisor’sand Trustee’s fees may be increased without approval ofthe Unitholders by amounts not exceeding proportionate

increases under the category “Services Less Rent ofShelter” in the Consumer Price Index for All UrbanConsumers or, if this category is not published, in acomparable category.

Organization Costs. You and the other Unitholderswill bear all or a portion of the organization costs andcharges incurred in connection with the establishment ofyour Portfolio. These costs and charges will include thecost of the preparation, printing and execution of the trustagreement, registration statement and other documentsrelating to your Portfolio, federal and state registration feesand costs, the initial fees and expenses of the Trustee,and legal and auditing expenses. The Public Offering Priceof Units includes the estimated amount of these costs.The Trustee will deduct these expenses from yourPortfolio’s assets at the end of the initial offering period.

Creation and Development Fee. The Sponsor willreceive a fee from your Portfolio for creating anddeveloping the Portfolio, including determining thePortfolio’s objectives, policies, composition and size,selecting service providers and information services andfor providing other similar administrative and ministerialfunctions. The creation and development fee is a chargeof $0.05 per Unit. The Trustee will deduct this amountfrom your Portfolio’s assets as of the close of the initialoffering period. No portion of this fee is applied to thepayment of distribution expenses or as compensation forsales efforts. This fee will not be deducted from proceedsreceived upon a repurchase, redemption or exchange ofUnits before the close of the initial public offering period.

Trustee’s Fee. For its services the Trustee willreceive the fee from your Portfolio set forth in the “FeeTable” (which includes the estimated amount ofmiscellaneous Portfolio expenses). The Trustee benefitsto the extent there are funds in the Capital and IncomeAccounts since these Accounts are non-interest bearingto Unitholders and the amounts earned by the Trusteeare retained by the Trustee. Part of the Trustee’scompensation for its services to your Portfolio isexpected to result from the use of these funds.

Compensation of Sponsor and Supervisor.The Sponsor and the Supervisor, which is an affiliate ofthe Sponsor, will receive the annual fee for providing

A-22

bookkeeping and administrative services and portfoliosupervisory services set forth in the “Fee Table”.
