Your Fund’s Performance at a Glance

• Vanguard 500 Index Fund returned about 12% for the fiscal year ended December 31, 2016. The fund closely tracked its target index, the Standard & Poor’s 500 Index, and exceeded the average return of its large-capitalization core fund peers.

• The fund offers investors exposure to 500 of the largest U.S. companies, which span many different industries and account for about three-fourths of the U.S. stock market’s value.

• The fund recorded positive returns in ten of the 11 market sectors, with seven posting double-digit gains.

• Information technology, the fund’s largest sector, was the top contributor; financials, energy, and industrials also added significantly to returns. Only health care stocks declined.

• Over the past ten years, the fund posted an average annual return of about 7%, in line with its benchmark and more than 1 percentage point higher than its peer-fund average.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

If you’re like most investors, a big question on your mind is: What’s in store for the markets and the economy in 2017?

At Vanguard, we’re just as curious about the immediate future. But our curiosity is tempered by our belief that forecasts should give a range of possible outcomes, not pinpoint predictions. After all, there are bound to be occurrences the experts won’t see coming.

What really matters for investors

In 2016, we saw two cases in point: The United Kingdom’s June vote to exit the European Union and the November election of Donald Trump as U.S. president. Both unexpected outcomes triggered swift market reactions. But despite some short-term volatility, the markets’ 12-month performance as of December 31, 2016, proved to be less dramatic. U.S. stocks posted healthy returns, and U.S. bonds provided returns close to their long-term averages. International stocks and bonds also advanced, although returns for U.S. investors were reduced by the strength of the U.S. dollar.

The surprises of 2016 remind us to be skeptical of overly precise short-term predictions about 2017. At the cusp of a new year, market prognosticators forecast where the Standard & Poor’s 500 Index or the yield on the 10-year Treasury note will end up in 12 months. Such predictions can be attention-getting. They can also be dead wrong.

Investors are better off taking note of long-term trends that stand to influence our economies and markets. We’re watching these trends closely, and we discuss our latest assessment in our 2017 economic and market outlook, which you can read at vanguard.com/research.

Our global economic outlook: Expect stabilization, not stagnation

One phenomenon in particular that we’re watching is the low-growth, low-interest-rate environment that has marked the global economy since the 2008–09 financial crisis. We don’t think this economic backdrop is simply the result of cyclically weak demand or long-term stagnation. Instead, certain structural forces are contributing: Falling technology costs are restraining the amounts businesses are spending on capital investment, an aging population is weighing on growth in the developed world, and the free movement of capital and products across the globe has restrained prices and wages.

In the near term, these forces will continue to dampen growth, inflation, and interest rates. They also make it unlikely that further monetary stimulus from central banks will do much to spur growth.

I realize this all may sound gloomy, but that’s not how we see it. We expect global growth to stabilize at more modest levels, not stagnate. The world isn’t headed for Japanese-style deflation, in which a widespread sustained drop in prices puts economic activity into hibernation.

In fact, we believe that global growth could pick up modestly over time. Our expectation is based on a potential rebound in productivity as new digital technologies are used more effectively. We also anticipate a slight recovery in the labor force as the baby boom generation finishes its transition to retirement, nudging up demand for workers.

Put expansion in perspective

Looking to the United States, the world’s largest economy remains firmly on a long-term-growth path of about 2% per year. That’s lower than the historical average of 3.25% since 1950. We see such growth at this level as fundamentally sound, rather than abnormally low. Our evaluation takes into account lower U.S. population growth and the reality that the economic expansion from the 1980s until the financial crisis was fueled by debt, distorting the numbers.

Turning to prices, we think that core U.S. inflation should modestly exceed 2% in 2017. That, in turn, will support further interest rate hikes by the Federal Reserve, similar to the one at the end of 2016.

We expect the Fed to raise rates in 2017 before taking an extended pause, and we see the federal funds rate staying below 2% through at least 2018.

Prepare for muted returns

And what about prospects for the markets? Vanguard’s outlook for global stocks and bonds remains the most guarded in ten years, given fairly high stock valuations

Expect more modest returns, rely on time-tested principles

In Vanguard’s economic and market outlook for 2017, Global Chief Economist Joseph Davis

and his team offer a projection of more modest returns from the global stock and bond

markets. They caution that, over the next decade, returns for a balanced portfolio are likely

to be moderately below long-run historical averages.

The team’s simulations indicate that for the decade ending in 2026, the average annualized

return of a 60% stock/40% bond portfolio is likely to be centered in the 3%–5% range after

inflation. That’s below the actual average after-inflation return of 6% for the same portfolio

for the nine decades since 1926.

Ultimately, our global market outlook points toward a somewhat more challenging environment,

yet one in which, over time, investors with an appropriate level of discipline, diversification, and

patience are likely to be rewarded with reasonable inflation-adjusted returns.

For more information about our expectations and the probability of various outcomes, see 2017

Economic and Market Outlook: Stabilization, Not Stagnation, available at vanguard.com/research.

IMPORTANT: The projections and other information generated by the Vanguard Capital Markets Model^®(VCMM)

regarding the likelihood of various investment outcomes are hypothetical in nature, do not reflect actual investment

results, and are not guarantees of future results. Distribution of return outcomes from the VCMM are derived

from 10,000 simulations for each modeled asset class. Simulations as of September 30, 2016. Results from the

model may vary with each use and over time. For more information, see the note at the end of this letter.

and the low-interest-rate environment. We don’t expect global bond yields to increase materially from year-end 2016 levels.

Our outlook for global equities is annualized returns of 5%–8% over the next decade. This outlook isn’t bearish, but is actually fairly positive when you take into account the current low-rate environment. (See the box titled Expect more modest returns, rely on time-tested principles for more.)

Focus on the four keys to investment success

Significant trends often happen gradually. Like shifting tides, they’re sometimes barely noticeable at first but ultimately can change the landscape entirely. Other times, apparent trends can end up receding before they have much of a long-term impact. Given the future’s inherent unpredictability, it’s not reasonable to expect a surefire block-buster revelation from any prognosticator or investment firm.

What to conclude, then? No matter what scenario plays out, we believe investors have the best chance for success if they stay focused on what they can control: their goals, asset allocation, and investment costs, along with the discipline to stick to a plan. As Tim Buckley, our chief investment officer, likes to say, this can be easy to say but harder to do, especially in times of uncertainty. Investors who can stay focused on those four keys will find themselves well-positioned to weather any market.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer
January 16, 2017

IMPORTANT: The projections and other information generated by the Vanguard Capital Markets Model regarding
the likelihood of various investment outcomes are hypothetical in nature, do not reflect actual investment results,
and are not guarantees of future results. VCMM results will vary with each use and over time.
The VCMM projections are based on a statistical analysis of historical data. Future returns may behave differently from the
historical patterns captured in the VCMM. More important, the VCMM may be underestimating extreme negative scenarios
unobserved in the historical period on which the model estimation is based.
The VCMM is a proprietary financial simulation tool developed and maintained by Vanguard’s Investment Strategy Group.
The model forecasts distributions of future returns for a wide array of broad asset classes. Those asset classes include U.S.
and international equity markets, several maturities of the U.S. Treasury and corporate fixed income markets, international
fixed income markets, U.S. money markets, commodities, and certain alternative investment strategies. The theoretical and
empirical foundation for the Vanguard Capital Markets Model is that the returns of various asset classes reflect the compensation
investors require for bearing different types of systematic risk (beta). At the core of the model are estimates of the dynamic
statistical relationship between risk factors and asset returns, obtained from statistical analysis based on available monthly
financial and economic data. Using a system of estimated equations, the model then applies a Monte Carlo simulation method
to project the estimated interrelationships among risk factors and asset classes as well as uncertainty and randomness over
time. The model generates a large set of simulated outcomes for each asset class over several time horizons. Forecasts are
obtained by computing measures of central tendency in these simulations. Results produced by the tool will vary with each
use and over time.

500 Index Fund

Notes to Financial Statements

Vanguard 500 Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers four classes of shares: Investor Shares, ETF Shares, Admiral Shares, and Institutional Select Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares and Institutional Select Shares are designed for investors who meet certain administrative, service, and account-size criteria. Institutional Select Shares were issued on June 24, 2016.

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: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks 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.

Futures contracts are valued at their quoted daily settlement prices. The aggregate settlement values 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 Net Assets 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 December 31, 2016, 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 aggregate settlement values at each quarter-end during the period.

500 Index Fund

3. 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 (December 31, 2013–2016), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

5. Securities Lending: To earn additional income, the fund lends its securities to qualified institutional borrowers. Security loans are subject to termination by the fund at any time, and are required to be secured at all times by collateral in an amount at least equal to the market value of securities loaned. Daily market fluctuations could cause the value of loaned securities to be more or less than the value of the collateral received. When this occurs, the collateral is adjusted and settled on the next business day. The fund further mitigates its counterparty risk by entering into securities lending transactions only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master securities lending agreements with its counterparties. The master securities lending agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 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 included in Management and Administrative expenses on the fund’s Statement of Operations. 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 December 31, 2016, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. 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.

500 Index Fund

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

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. Vanguard does not require reimbursement in the current period for certain costs of operations (such as deferred compensation/benefits and risk/insurance costs); the fund’s liability for these costs of operations is included in Payables to Vanguard on the Statement of Net Assets.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At December 31, 2016, the fund had contributed to Vanguard capital in the amount of $20,425,000, representing 0.01% of the fund’s net assets and 8.17% of Vanguard’s capitalization. The fund’s trustees and officers are also 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).

The following table summarizes the market value of the fund’s investments as of December 31, 2016, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	281,656,436	—	—
Temporary Cash Investments	1,187,838	70,074	—
Futures Contracts—Liabilities¹	(4,223)	—	—
Total	282,840,051	70,074	—
1 Represents variation margin on the last day of the reporting period.

500 Index Fund

D. At December 31, 2016, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	9,490	1,061,077	(8,733)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

E. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes. These differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2016, the fund realized $6,081,373,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2016, the fund had $57,455,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $587,670,000 to offset taxable capital gains realized during the year ended December 31, 2016. At December 31, 2016, the fund had available capital losses totaling $840,474,000 that may be carried forward indefinitely to offset future net capital gains. Capital loss carryforwards of $1,763,970,000 expired on December 31, 2016; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At December 31, 2016, the cost of investment securities for tax purposes was $184,456,616,000. Net unrealized appreciation of investment securities for tax purposes was $98,457,732,000, consisting of unrealized gains of $102,245,916,000 on securities that had risen in value since their purchase and $3,788,184,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2016, the fund purchased $59,104,325,000 of investment securities and sold $19,071,086,000 of investment securities, other than temporary cash investments. Purchases and sales include $35,983,194,000 and $9,053,787,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2016 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Special 2016 tax information (unaudited) for Vanguard 500 Index Fund

This information for the fiscal year ended December 31, 2016, is included pursuant to provisions
of the Internal Revenue Code.

The fund distributed $5,258,636,000 of qualified dividend income to shareholders during the
fiscal year.

For corporate shareholders, 91.8% of investment income (dividend income plus short-term gains,
if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

About Your Fund’s Expenses

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 fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (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 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.

	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
500 Index Fund	6/30/2016	12/31/2016	Period

ETF Shares	1,000.00	1,078.20	0.21
Admiral Shares	1,000.00	1,078.12	0.21

Admiral Shares	1,000.00	1,024.94	0.20
Institutional Select Shares	1,000.00	1,025.09	0.05

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that
period are 0.12% for Investor Shares, 0.04% for ETF Shares, 0.04% for Admiral Shares, and 0.01% for Institutional Select Shares. The dollar
amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period,
multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period
(184/366).

Glossary

30-Day SEC Yield. A fund’s 30-day SEC yield is derived using a formula specified by the U.S. Securities and Exchange Commission. Under the formula, data related to the fund’s security holdings in the previous 30 days are used to calculate the fund’s hypothetical net income for that period, which is then annualized and divided by the fund’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s income is based on its current market yield to maturity (for bonds), its actual income (for asset-backed securities), or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the fund’s actual experience. As a result, the fund’s income distributions may be higher or lower than implied by the SEC yield.

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. For this report, beta is based on returns over the past 36 months for both the fund and the index. Note that a fund’s beta should be reviewed in conjunction with its R-squared (see definition). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Dividend Yield. Dividend income earned by stocks, expressed as a percentage of the aggregate market value (or of net asset value, for a fund). The yield is determined by dividing the amount of the annual dividends by the aggregate value (or net asset value) at the end of the period. For a fund, the dividend yield is based solely on stock holdings and does not include any income produced by other investments.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Equity Exposure. A measure that reflects a fund’s investments in stocks and stock futures. Any holdings in short-term reserves are excluded.

Expense Ratio. A fund’s total annual operating expenses expressed as a percentage of the fund’s average net assets. The expense ratio includes management and administrative expenses, but does not include the transaction costs of buying and selling portfolio securities.

Foreign Holdings. The percentage of a fund represented by securities or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0. For this report, R-squared is based on returns over the past 36 months for both the fund and the index.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

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 on an at-cost basis.

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 198 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. 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 charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

If you’re like most investors, a big question on your mind is: What’s in store for the markets and the economy in 2017?

What really matters for investors

Our global economic outlook: Expect stabilization, not stagnation

In the near term, these forces will continue to dampen growth, inflation, and interest rates. They also make it unlikely that further monetary stimulus from central banks will do much to spur growth.
