See the inside front cover for important information about access to your fund's annual and semiannual shareholder reports.

The Securities and Exchange Commission (SEC) has not approved or disapproved these securities or passed upon the adequacy of this prospectus. Any representation to the contrary is a criminal offense.

Important information about access to shareholder reports

Beginning on January 1, 2021, as permitted by regulations adopted by the SEC, paper copies of your fund's annual and semiannual shareholder reports will no longer be sent to you by mail, unless you specifically request them. Instead, you will be notified by mail each time a report is posted on the website and will be provided with a link to access the report.

If you have already elected to receive shareholder reports electronically, you will not be affected by this change and do not need to take any action. You may elect to receive shareholder reports and other communications from the fund electronically by contacting your financial intermediary (such as a broker-dealer or bank) or, if you invest directly with the fund, by calling Vanguard at one of the phone numbers on the back cover of this prospectus or by logging on to vanguard.com.

You may elect to receive paper copies of all future shareholder reports free of charge. If you invest through a financial intermediary, you can contact the intermediary to request that you continue to receive paper copies. If you invest directly with the fund, you can call Vanguard at one of the phone numbers on the back cover of this prospectus or log on to vanguard.com. Your election to receive paper copies will apply to all the funds you hold through an intermediary or directly with Vanguard.

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of large-, mid-, and small-capitalization stocks of U.S. companies and is screened for certain environmental, social, and corporate governance criteria.

Fees and Expenses

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Shareholder Fees

(Fees paid directly from your investment)

Transaction Fee on Purchases and Sales	None through Vanguard (Broker fees vary)
Transaction Fee on Reinvested Dividends	None through Vanguard (Broker fees vary)

Annual Fund Operating Expenses

(Expenses that you pay each year as a percentage of the value of your investment)

Management Fees	0.10%
12b-1 Distribution Fee	None

Other Expenses	0.02%

Total Annual Fund Operating Expenses	0.12%

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to sell your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$12	$39	$68	$154

This example does not include the brokerage commissions that you may pay to buy and sell shares of the Fund.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6% of the average value of its portfolio.

Principal Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the FTSE US All Cap Choice Index. The Index, which is market capitalization-weighted, is composed of large-, mid-, and small-cap stocks of companies located in the United States that are screened for certain environmental, social, and corporate governance (ESG) criteria by the Index sponsor, which is independent of Vanguard. The FTSE US All Cap Choice Index

excludes stocks of companies that FTSE Group (FTSE) determines engage in and/or derive threshold amounts of revenue from the following activities: (i) produce adult entertainment; (ii) produce alcoholic beverages; (iii) produce tobacco products; (iv) produce (or produce specific and critical parts or services for) nuclear weapon systems, chemical or biological weapons, cluster munitions, and anti-personnel mines; (v) produce other weapons for military use; (vi) produce firearms or ammunition for non-military use; (vii) own proved or probable reserves in coal, oil, or gas, or any company that FTSE determines has a primary business activity in: (a) the exploration and drilling for, as well as producing, refining, and supplying, oil and gas products, (b) the supply of equipment and services to oil fields and offshore platforms, (c) the operations of pipelines carrying oil, gas, or other forms of fuel, (d) integrated oil and gas companies that provide a combination of services listed in (a)-(c) above, including the refining and marketing of oil and gas products, or (e) the exploration for or mining of coal; (viii) provide gambling services; and (ix) generate revenues from nuclear power production. The level of involvement in, or amount of revenue earned from, certain business lines or activities can vary from one company to another. The Index methodology also excludes the stocks of companies that, as FTSE determines, do not meet the labor, human rights, environmental, and anti-corruption standards as defined by the United Nations Global Compact Principles, as well as companies that do not meet certain diversity criteria.

See the Securities Selection section for more information regarding the Index exclusions. The components of the Index are likely to change over time.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Principal Risks

An investment in the Fund could lose money over short or long periods of time. You should expect the Fund's share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund's performance:

•Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund's target index tracks a subset of the U.S. stock market, which could cause the Fund to perform differently from the overall market. In addition, the Fund's target index may, at times, become focused in stocks of a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of that sector.

•Investment style risk, which is the chance that returns from small- and mid-capitalization stocks will trail returns from the overall stock market. Historically, small- and mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently. The stock prices of small and mid-size companies tend to experience greater volatility because, among other things, these companies tend to be more sensitive to changing economic conditions.

•ESG investing risk, which is the chance that the stocks screened by the index sponsor for ESG criteria generally will underperform the stock market as a whole or that the particular stocks selected for the FTSE US All Cap Choice Index will, in the aggregate, trail returns of other funds screened for ESG criteria. There are significant differences in interpretations of what it means for a company to meet ESG criteria. The index sponsor's assessment of a company, based on the company's level of involvement in a particular industry or the index sponsor's own ESG criteria, may differ from that of other funds or of the advisor's or an investor's assessment of such company. As a result, the companies deemed eligible by the index sponsor may not reflect the beliefs and values of any particular investor and may not exhibit positive or favorable ESG characteristics. The index provider is dependent on the availability of timely and accurate ESG data being reported by companies in the index to evaluate their ESG criteria. In addition, the Fund's target index may, at times, become focused in stocks of a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of that sector.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

•The Fund's ETF Shares are listed for trading on Cboe BZX Exchange, Inc., and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

•Although the Fund's ETF Shares are listed for trading on Cboe BZX Exchange, Inc., it is possible that an active trading market may not be maintained.

•Trading of the Fund's ETF Shares may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Fund's ETF Shares may also be halted if (1) the shares are delisted from Cboe BZX Exchange, Inc., without first being listed on another exchange or (2) Cboe BZX Exchange, Inc., officials determine that such

action is appropriate in the interest of a fair and orderly market or for the protection of investors.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares may be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

Purchase and Sale of Fund Shares

ETF Shares may only be bought and sold in the secondary market through a brokerage firm. The price you pay or receive for ETF Shares will be the prevailing market price, which may be more (premium) or less (discount) than the NAV of the shares. The brokerage firm may charge you a commission to execute the transaction. Unless imposed by your brokerage firm, there is no minimum dollar amount you must invest and no minimum number of shares you must buy. ETF Shares of the Fund cannot be directly purchased from or redeemed with the Fund, except by certain authorized broker-dealers. These broker-dealers may purchase and redeem ETF Shares only in large blocks (Creation Units), typically in exchange for baskets of securities.

An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase ETF Shares (bid) and the lowest price a seller is willing to accept for ETF Shares (ask) when buying or selling shares in the secondary market (bid-ask spread). Recent information, including information on the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is available online at www.vanguard.com.

Tax Information

The Fund's distributions may be taxable as ordinary income or capital gain. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply.

Payments to Financial Intermediaries

The Fund and its investment advisor do not pay financial intermediaries for sales of Fund shares.
