Dear Shareholder,

Recent volatility in financial markets—affecting stocks, bonds, and commodities— has been a good reminder of the wise old adage, “Never keep all your eggs in one basket.” Maintaining balance and diversification in your investment portfolio can help to both limit risk and set you up for long-term success.

It’s understandable why some investors might become complacent after a long market run-up like the one that lifted stock prices, especially U.S. stock prices, in the years following the global financial crisis. But failing to rebalance regularly can leave a portfolio with a much different mix of assets than intended and, often, more risk than intended.

Balance across and diversification within asset classes are powerful tools for managing risk and achieving your investment goals. A portfolio’s allocation will determine a large portion of its long- term return and also the majority of its volatility risk. A well-diversified portfolio is less vulnerable to significant swings in the performance of any one segment of the asset classes in which it invests.

Balance and diversification will never eliminate the risk of loss, nor will they guarantee positive returns in a declining market. But they should reduce the chance that you’ll suffer disproportionate losses in one particular high-flying asset class or sector when it comes back to earth. And exposure to all key market components should give you at least some participation in the sectors that are performing best at any given time.

Vanguard is committed to helping you achieve balance and diversification in your portfolios to help meet your invest-ment goals. We thank you for your continued loyalty.

Sincerely,

Mortimer J. Buckley Chairman and Chief Executive Officer October 14, 2019

A Note From Our Chairman

Tim BuckleyChairman and Chief Executive Officer

• For the 12 months ended September 30, 2019, the six Vanguard Institutional Target

Retirement Funds covered in this report recorded returns ranging from 3.45% for the

Institutional Target Retirement 2035 Fund to 6.73% for the Institutional Target Retirement

Income Fund. (The funds with target dates of 2040 through 2065 are covered in a separate

report.) The funds with a greater allocation to bonds performed best.

• Each fund performed in line with its composite benchmark after expenses. The

Institutional Target Retirement Funds invest all of their assets in Vanguard index funds

that seek to match the performance of broad stock and bond market indexes.

• Worries about the pace of global economic growth and plans by numerous central

banks to loosen monetary policies encouraged investment in bonds, sending their yields

lower and their prices markedly higher. Broad measures of both the U.S. and non-U.S.

investment-grade bond markets returned about 10% during the funds’ fiscal year. Stocks,

in contrast, cooled. The broad U.S. stock market gained about 3%, while international

stocks returned roughly –1% in U.S. dollars.

• Vanguard Institutional Target Retirement Funds are designed to reach an allocation

of 70% bonds and 30% stocks within seven years after their target dates.

• From their inception dates through September 30, the funds had average annual

returns that ranged from 4.77% for the Institutional Target Retirement Income Fund

to 6.64% for the Institutional Target Retirement 2035 Fund.

About Your Fund’s Expenses

3

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A typical fund’s expenses are expressed as a percentage of its average net assets. The Institutional Target Retirement Funds have no direct expenses, but each fund bears its proportionate share of the costs for the underlying funds in which it invests. These indirect expenses make up the acquired fund fees and expenses, also expressed as a percentage of average net assets.

The following examples are intended to help you understand the ongoing cost (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period. The costs were calculated using the acquired fund fees and expenses for each Institutional Target Retirement Fund.

The accompanying table illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The ”Ending Account Value“ shown is derived from the fund‘s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading ”Expenses Paid During Period.“

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund‘s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transaction costs incurred by the fund for buying and selling securities. Further, the expenses do not include any purchase, redemption, or account service fees described in the fund prospectus. If such fees were applied to your account, your costs would be higher. Your fund does not carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to your fund’s current prospectus.

The calculations are based on the acquired fund fees and expenses for the most recent six-month period. The funds’ annualized expensefigures for that period are (in order as listed from top to bottom above) 0.09%, 0.09%, 0.09%, 0.09%, 0.09%, and 0.09%. The dollaramounts shown as ”Expenses Paid” are equal to the annualized expense figures for the underlying funds multiplied by the averageaccount value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days inthe most recent 12-month period (183/365).

All of the returns in this report represent past performance, which is not a guarantee of future results that may be achieved by the fund. (Current performance may be lower or higher thanthe performance data cited. For performance data current to the most recent month-end, visitour website at vanguard.com/performance.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost. The returns shown do not reflect taxes that a shareholder would pay on fund distributions or on the sale of fund shares.

Notes to Financial Statements


Vanguard Institutional Target Retirement Income Fund is registered under the Investment Company

Act of 1940 as an open-end investment company, or mutual fund. The fund follows a balanced

investment strategy by investing in selected Vanguard funds to achieve its targeted allocation of

assets to U.S. and international stocks, and U.S. and international bonds. Financial statements and

other information about each underlying fund are available on vanguard.com.

A. The following significant accounting policies conform to generally accepted accounting principles

for U.S. investment companies. The fund consistently follows such policies in preparing its financial

statements.

1. Security Valuation: Investments are valued at the net asset value of each underlying Vanguard

fund determined as of the close of the New York Stock Exchange (generally 4 p.m., Eastern time)

on the valuation date.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company

and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for

all open federal income tax years (September 30, 2016–2019), and has concluded that no provision

for federal income tax is required in the fund’s financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date. Distributions

are determined on a tax basis and may differ from net investment income and realized capital gains

for financial reporting purposes.

4. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”)

participate in a $4.3 billion committed credit facility provided by a syndicate of lenders pursuant to

a credit agreement that may be renewed annually; each fund is individually liable for its borrowings,

if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes,

and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating

funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn

amount of the facility; these fees are allocated to the funds based on a method approved by the

fund’s board of trustees and borne by the funds in which the fund invests (see Note B). Any

borrowings under this facility bear interest at a rate based upon the higher of the one-month

London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus

an agreed-upon spread.

The fund had no borrowings outstanding at September 30, 2019, or at any time during the period

then ended.

5. Other: Income and capital gain distributions received are recorded on the ex-dividend date.

Security transactions are accounted for on the date securities are bought or sold. Costs used to

determine realized gains (losses) on the sale of investment securities are those of the specific

securities sold.

B. In accordance with the terms of a Funds’ Service Agreement (the “FSA”) between Vanguard

and the fund, Vanguard furnishes to the fund investment advisory, corporate management,

administrative, marketing, and distribution services at Vanguard’s cost of operations (as defined

by the FSA). These costs of operations are allocated to the fund based on methods and guidelines

approved by the board of trustees. The FSA provides that expenses otherwise allocable to Vanguard

funds-of-funds may be reduced or eliminated to the extent of savings realized by the underlying

12


Vanguard funds by virtue of being part of a fund-of-funds. Accordingly, all expenses for services

provided by Vanguard to the fund and all other expenses incurred by the fund during the period

ended September 30, 2019, were borne by the underlying Vanguard funds in which the fund

invests. The fund’s trustees and officers are also trustees and officers, respectively, of the

underlying Vanguard funds, as well as directors and employees, respectively, of Vanguard.

C. Various inputs may be used to determine the value of the fund’s investments. These inputs are

summarized in three broad levels for financial statement purposes. The inputs or methodologies

used to value securities are not necessarily an indication of the risk associated with investing in

those securities.

Level 1—Quoted prices in active markets for identical securities.

Level 2—Other significant observable inputs (including quoted prices for similar securities, interest

rates, prepayment speeds, credit risk, etc.).

Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine

the fair value of investments). Any investments valued with significant unobservable inputs are

noted on the Statement of Net Assets.

At September 30, 2019, 100% of the market value of the fund’s investments was determined

based on Level 1 inputs.

D. Permanent differences between book-basis and tax-basis components of net assets are

reclassified among capital accounts in the financial statements to reflect their tax character.

These reclassifications have no effect on net assets or net asset value per share. As of period

end, permanent differences primarily attributable to the accounting for distributions in connection

with fund share redemptions were reclassified between the following accounts:

Amount

($000)

Paid-in Capital 1,956

Total Distributable Earnings (Loss) (1,956)

Temporary differences between book-basis and tax-basis components of total distributable

earnings (loss) arise when certain items of income, gain, or loss are recognized in different periods

for financial statement and tax purposes; these differences will reverse at some time in the future.

The differences are primarily related to the tax deferral of losses on wash sales and payables for

distributions. As of period end, the tax-basis components of total distributable earnings (loss) are

detailed in the table as follows:

Amount

($000)

Undistributed Ordinary Income 3,434

Undistributed Long-Term Gains —

Capital Loss Carryforwards (Non-expiring) —

Net Unrealized Gains (Losses) 555,549

As of September 30, 2019, gross unrealized appreciation and depreciation for investments based on cost for U.S. federal income tax purposes were as follows:

Amount ($000)

Tax Cost 5,791,559

Gross Unrealized Appreciation 561,589

Gross Unrealized Depreciation (6,040)

Net Unrealized Appreciation (Depreciation) 555,549

E. Capital shares issued and redeemed were:

Issued 60,874 77,323


Redeemed (47,640) (56,429)

Net Increase (Decrease) in Shares Outstanding 20,789 27,048

At September 30, 2019, one shareholder was the record or beneficial owner of 31% of the fund’s net assets. If the shareholder were to redeem its investment in the fund, the redemption might lead to the realization of taxable capital gains.

2. Futures Contracts: The fund uses stock and bond futures contracts to a limited extent, with the

objectives of maintaining full exposure to the market and maintaining its target asset allocation. The

primary risks associated with the use of futures contracts are imperfect correlation between changes

in market values of investments held by the fund and the prices of futures contracts, and the

possibility of an illiquid market. Counterparty risk involving futures is mitigated because a regulated

clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty

risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing

brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The

clearinghouse imposes initial margin requirements to secure the fund’s performance and requires

daily settlement of variation margin representing changes in the market value of each contract. Any

assets pledged as initial margin for open contracts are noted in the Statement of Net Assets.

Futures contracts are valued at their quoted daily settlement prices. The notional amounts of

the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the

contracts are recorded in the Statement of Assets and Liabilities as an asset (liability) and in the

Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed,

when they are recorded as realized futures gains (losses).

During the year ended September 30, 2019, the fund’s average investments in long and short

futures contracts represented less than 1% and 0% of net assets, respectively, based on the

average of the notional amounts at each quarter-end during the period. The fund had no open

futures contracts at September 30, 2019.

The differences are primarily related to the tax deferral of losses on wash sales. As of period end, the tax-basis components of total distributable earnings (loss) are detailed in the table as follows:

Opinions on the Financial Statements

We have audited the accompanying statements of net assets and statements of assets and

liabilities of Vanguard Institutional Target Retirement Income Fund, Vanguard Institutional Target

Retirement 2015 Fund, Vanguard Institutional Target Retirement 2020 Fund, Vanguard Institutional

Target Retirement 2025 Fund, Vanguard Institutional Target Retirement 2030 Fund and Vanguard

Institutional Target Retirement 2035 Fund (six of the funds constituting Vanguard Chester Funds,

hereafter collectively referred to as the “Funds”) as of September 30, 2019, the related statements

of operations for the year ended September 30, 2019, the statements of changes in net assets for

each of the two years in the period ended September 30, 2019, including the related notes, and the

financial highlights for each of the periods indicated therein (collectively referred to as the “financial

statements”). In our opinion, the financial statements present fairly, in all material respects, the

financial position of each of the Funds as of September 30, 2019, the results of each of their

operations for the year then ended, the changes in each of their net assets for each of the two

years in the period ended September 30, 2019 and each of the financial highlights for each of the

periods indicated therein in conformity with accounting principles generally accepted in the United

States of America.

Basis for Opinions

These financial statements are the responsibility of the Funds’ management. Our responsibility

is to express an opinion on the Funds’ financial statements based on our audits. We are a public

accounting firm registered with the Public Company Accounting Oversight Board (United States)

(“PCAOB”) and are required to be independent with respect to the Funds in accordance with the

U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange

Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of

the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable

assurance about whether the financial statements are free of material misstatement, whether

due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the

financial statements, whether due to error or fraud, and performing procedures that respond to

those risks. Such procedures included examining, on a test basis, evidence regarding the amounts

and disclosures in the financial statements. Our audits also included evaluating the accounting

principles used and significant estimates made by management, as well as evaluating the overall

presentation of the financial statements. Our procedures included confirmation of securities owned

as of September 30, 2019 by correspondence with the transfer agent. We believe that our audits

provide a reasonable basis for our opinions.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your

best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also

serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard

funds and provides services to them.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation

with Vanguard or the funds they oversee, apart from the sizable personal investments they have

made as private individuals. The independent board members have distinguished backgrounds

in business, academia, and public service. Each of the trustees and executive officers oversees

212 Vanguard funds.

Information for each trustee and executive officer of the fund appears below. That information,

as well as the Vanguard fund count, is as of the date on the cover of this fund report. The mailing

address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482. More information

about the trustees is in the Statement of Additional Information, which can be obtained, without
