Chairman’s Letter

Dear Shareholder,

The fiscal year ended December 31, 2015, was a tumultuous one for the world’s financial markets, and the broad U.S. stock market navigated a bumpy road to modest gains. Stocks of larger domestic companies such as those held in Vanguard 500 Index Fund generally outperformed their mid- and small-sized counterparts.

In this investment environment, your fund returned 1.25% for Investor Shares, closely tracking its benchmark, the Standard & Poor’s 500 Index, and surpassing the –0.66% average return of its peers.

Results among the fund’s ten market sectors were mixed. Half posted gains; consumer discretionary, technology, and health care stocks added most to returns. Energy stocks were a notable drag on performance.

If you hold shares of the fund in a taxable account, you may wish to review the section on after-tax returns that appears later in this report.

Despite troubles, U.S. stocks eked out a seventh year of gains
U.S. stocks returned 0.48% for the 12 months ended December 31, 2015. Although the broad market recorded its worst performance since 2008, it still posted gains for the seventh straight calendar year when dividends are factored into returns.

Stocks rose modestly over the first half of the year but slid in August and September as concerns mounted that China’s economic slowdown would spread globally. Falling oil and commodity prices also affected economies and markets across the world for better or worse. Central banks in Europe and Asia bolstered their stimulus efforts against weak growth and low inflation. And in December, the Federal Reserve ended months of uncertainty when it raised the target for short-term interest rates to 0.25%–0.5%.

International stocks returned about –5%, restrained by the U.S. dollar’s strength against many foreign currencies. Emerging markets fared the worst.

U.S. bonds ended the year with a slender advance

The broad U.S. taxable bond market gained 0.55% over the 12 months; income accounted for the modestly positive result. The yield of the 10-year Treasury note ended December at 2.30%, up from 2.19% a year earlier. (Bond prices and yields move in opposite directions.)

Investors focused on the Fed’s stance on short-term interest rates and alternately embraced or avoided safe-haven assets depending on the stock market’s strength.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –6.02%, reduced by the

dollar’s strength against many foreign currencies. Without this currency effect, returns were modestly positive.

Although the Fed raised its target for short-term interest rates in mid-December, returns for money market funds and savings accounts remained limited by the 0%–0.25% levels in place for much of the past seven years.

Energy’s double-digit decline offset gains in several sectors

The 500 Index Fund invests in 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. As I mentioned, stocks of large-cap companies returned more than those of smaller companies, boosting your fund’s performance relative to the broad market.

Most segments of the U.S. economy grew, propped up by shoppers’ overall confidence and their willingness and ability to spend. This trend benefited the consumer discretionary and consumer staples sectors, which were among the market’s top performers. Internet retailers led the way in consumer discretionary; home improvement stores and restaurants also excelled. In consumer goods, notable showings came from tobacco, beverage, and packaged food companies.

The fund expense ratios shown are from the prospectus dated April 28, 2015, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2015, the fund’s expense ratios were 0.16% for Investor Shares, 0.05% for ETF Shares, and 0.05% for Admiral Shares. The peer-group expense ratio is derived from data provided by Lipper, a Thomson Reuters Company, and captures information through year-end 2014.

Peer group: Large-Cap Core Funds.

The information technology and health care sectors also boosted performance; however, their returns paled compared with those of some robust recent periods. In IT, gains from internet and software firms were partially offset by poor results from technology hardware and communications equipment companies.

Merger-and-acquisition activity, vibrant drug pipelines, and favorable long-term demographic and economic trends lifted the health care sector. But political controversy over high drug prices and lofty valuations of biotechnology stocks led to a few stumbles. The fund’s tiny holding in telecommunications was also positive.

Much of the contribution made by these industries was erased by a double-digit decline in energy. The lengthy and sharp slide of oil prices punished the sector. Their effect was worsened by high production levels from some leading oil-producing countries and concerns about the slower growth in China, the world’s largest oil importer.

Natural gas prices also dropped, though not as dramatically. Some integrated oil and gas firms held up better than others, but the majority of companies engaged in production and exploration as well as services and distribution suffered.

The figures shown represent past performance, which is not a guarantee of future results. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our 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.

Stocks in the financial, industrials, materials, and utilities sectors also weighed on the fund’s performance.

The fund’s long-term record continues to be admirable

Over the last ten years, Vanguard 500 Index Fund’s Investor Shares have produced an average annual return of 7.18%. That’s more than 1 percentage point better than the average return of peer funds.

Most important, the fund has succeeded in meeting its primary objective of closely tracking its index over the long-term. That was no easy feat during a period that included the worst global recession since the Great Depression. This success is a tribute to the experience, talent, and sophisticated systems of the fund’s advisor, Vanguard Equity Index Group. Low expenses––which allow you to keep more of the fund’s return—have helped as well.

Vanguard’s outlook for investors: Not bearish, but cautious

In Vanguard’s recently published global economic and investment outlook, Global Chief Economist Joseph Davis and his team discuss various market and economic events 2016 may bring, along with challenges and opportunities for investors.

Our forecast includes “frustratingly fragile” economic growth and more modest long-term returns from the global stock and bond markets. The report cautions that for the decade ending 2025, returns for a balanced portfolio are likely to be moderately below historical averages.

Our simulations indicate that the average annualized returns of a 60% equity/40% bond portfolio for the decade are most likely to be centered in the 3%–5% range after inflation, below the actual average after-inflation return of 5.5% for the same portfolio since 1926.

Even so, Vanguard’s steadfast belief in its principles for investing success—focusing on clear goals, a suitable asset allocation, low costs, and long-term discipline—remains unchanged.

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

Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.

IMPORTANT: The projections or 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 VCMM derived from 10,000 simulations for U.S. equity returns and fixed income returns. Simulations as of September 30, 2015. Results from the model may vary with each use and over time. For more information, please see page 7.

To reach your long-term goals, be realistic and try to save more

Although there have been times when it felt as if stocks and bonds were riding a roller coaster, returns have generally risen in recent years. The broad global stock market in particular has posted some impressive gains since its turnaround began in 2009.

But 2015 served as a reminder that results aren’t always favorable. The U.S. stock and bond markets were barely positive, and international stocks and unhedged bonds finished in the red.

In Vanguard’s recently updated long-term look at the economy and markets, our global economists explain why they expect economic growth to remain “frustratingly fragile” and why their outlook for stock and bond markets is the most guarded since 2006. (For more details, see the box on page 6 and Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.)

Given these muted expectations, what’s the best course of action? I’ve often encouraged shareholders to focus on the things they can control. That advice holds true today.

Consider saving more than you think you may need. That’s one way you can prepare for the volatility that may lie ahead, particularly as markets adjust to changes in policies from the Fed and other central banks.

IMPORTANT: The projections or 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. 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 primary investment research and advice teams. 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 VCMM 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 from as early as 1960. 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.

And, as always, investors would be well- served to follow Vanguard’s principles for investing success:

• Goals. Create clear, appropriate investment goals.

• Balance. Develop a suitable asset allocation using broadly diversified funds.

• Cost. Minimize cost.

• Discipline. Maintain perspective and long-term discipline.

As with saving, each of these principles is within your control, and focusing on them can keep you on the right path.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

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 three classes of shares: Investor Shares, ETF Shares, and Admiral 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 are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective at the close of business on October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

26

500 Index Fund

During the year ended December 31, 2015, 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.

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, 2012–2015), 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.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, 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

27

500 Index Fund

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.

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, 2015, the fund had contributed to Vanguard capital in the amount of $19,191,000, representing 0.01% of the fund’s net assets and 7.68% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	218,575,502	—	—
Temporary Cash Investments	727,068	59,950	—
Futures Contracts—Liabilities1	(7,042)	—	—
Total	219,295,528	59,950	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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 2016	7,335	746,483	11,868

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, 2015, the fund realized $5,126,301,000 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, 2015, the fund had $48,966,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $733,524,000 to offset taxable capital gains realized during the year ended December 31, 2015. At December 31, 2015, the fund had available capital losses totaling $3,192,114,000 to offset future net capital gains. Of this amount, $1,763,970,000 is subject to expiration on December 31, 2016. Capital losses of $1,428,144,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards. Capital loss carryforwards of $6,044,000 expired on December 31, 2015; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At December 31, 2015, the cost of investment securities for tax purposes was $137,491,163,000. Net unrealized appreciation of investment securities for tax purposes was $81,871,357,000, consisting of unrealized gains of $87,278,396,000 on securities that had risen in value since their purchase and $5,407,039,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $37,105,407,000 of investment securities and sold $14,830,808,000 of investment securities, other than temporary cash investments. Purchases and sales include $19,682,785,000 and $7,643,689,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

H. On May 16, 2014, the fund acquired all of the net assets of Vanguard Tax-Managed Growth and Income Fund pursuant to a plan of reorganization approved by the funds’ board of trustees on September 26, 2013. The purpose of the transaction was to combine two funds with similar investment strategies. The acquisition was accomplished by a tax-free exchange of 19,420,000 of Vanguard 500 Index Fund’s capital shares for the 45,479,000 shares of Vanguard Tax-Managed Growth and Income Fund outstanding on May 16, 2014. Each class of shares of Vanguard Tax-Managed Growth and Income Fund was exchanged for the Admiral Shares of Vanguard 500 Index Fund. Vanguard Tax-Managed Growth and Income Fund’s net assets of $3,371,686,000, including $1,348,485,000 of unrealized appreciation, were combined with Vanguard 500 Index Fund’s net assets of $168,166,924,000, resulting in combined net assets of $171,538,610,000 on May 16, 2014.

I. Management has determined that no material events or transactions occurred subsequent to December 31, 2015, that would require recognition or disclosure in these financial statements.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard Index Funds and the Shareholders of Vanguard 500 Index Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard 500 Index Fund (constituting a separate portfolio of Vanguard Index Funds, hereafter referred to as the “Fund”) at December 31, 2015, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. 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, 2015 by correspondence with the custodian and brokers, by agreement to the underlying ownership records of the transfer agent and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.

Special 2015 tax information (unaudited) for Vanguard 500 Index Fund

This information for the fiscal year ended December 31, 2015, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $4,391,533,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 93.6% 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.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

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.

ETF Shares	1,000.00	1,001.22	0.30
Admiral Shares	1,000.00	1,001.32	0.25

ETF Shares	1,000.00	1,024.90	0.31
Admiral Shares	1,000.00	1,024.95	0.26

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 0.17% for Investor Shares, 0.06% for ETF Shares, and 0.05% for Admiral 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 (184/365).

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.

35

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 194 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. 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 Letter

Dear Shareholder,

After three straight years of double-digit returns, the broad U.S. stock market limped to results of less than 1 percent for the 12 months ended December 31, 2015. Small-capitalization stocks fared worse: They finished in negative territory, well behind their large-cap counterparts, as investors became more risk-averse in the uncertain environment. It was their worst annual performance since 2008.

Vanguard’s three small-cap U.S. index funds recorded returns that ranged from –4.78% for the Vanguard Small-Cap Value Index Fund to –2.64% for the Vanguard Small-Cap Growth Index Fund. The broader-based Vanguard Small-Cap Index Fund, which includes both growth and value stocks, fell in between, with a return of –3.78%. (All returns are for Investor Shares.)

All three funds closely tracked their target indexes. Although it is not the funds’ objective to outperform funds that invest in similar stocks, the Small-Cap Index Fund and Small-Cap Value Index Fund surpassed the average return of their peers. The Small-Cap Growth Index Fund trailed its comparable industry average by less than 1 percentage point.

If you hold any of these funds in a taxable account, you may wish to review the discussion of after-tax returns that appears later in this report.

Despite troubles, U.S. stocks eked out a seventh year of gains

U.S. stocks returned 0.48% for the 12 months. Although the broad market recorded its worst performance since 2008, it still posted gains for the seventh straight calendar year when dividends are factored into returns.

Stocks rose modestly over the first half of the year but slid in August and September as concerns mounted that China’s economic slowdown would spread globally. Falling oil and commodity prices also affected economies and markets across the world for better or worse. Central banks in Europe and Asia bolstered their stimulus efforts against weak growth and low inflation. And in

December, the Federal Reserve ended months of uncertainty when it raised the target for short-term interest rates to 0.25%–0.5%.

International stocks returned about –5%, restrained by the U.S. dollar’s strength against many foreign currencies. Emerging markets fared the worst.

U.S. bonds ended the year with a slender advance
The broad U.S. taxable bond market gained 0.55% over the 12 months; income accounted for the modestly positive result. The yield of the 10-year Treasury note ended December at 2.30%, up from 2.19% a year earlier. (Bond prices and yields move in opposite directions.)

Investors focused on the Fed’s stance on short-term interest rates and alternately embraced or avoided safe-haven assets depending on the stock market’s strength.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –6.02%, reduced by the dollar’s strength. Without this currency effect, returns were modestly positive.

Although the Fed raised its target for short-term interest rates in mid-December, returns for money market funds and savings accounts remained limited by the 0%–0.25% levels in place for much of the past seven years.

Small-cap stocks lagged in challenging markets
Small-cap stocks, which make up about 10% of the broad U.S. market, provide investors with both opportunities and challenges. Small companies generally have greater potential for growth than larger ones. They’re often younger and nimbler and can sometimes find a market niche or capitalize on a market trend that leads to a surge in profits. At the same time, small companies are usually more vulnerable to setbacks; they don’t benefit from the diversification of business lines or the resources and cash reserves of larger firms.

When broader markets are unsettled, investors have traditionally favored the relative safety provided by larger, more established companies, whose results tend to be more predictable and less volatile. Small-caps, which led large-caps in cumulative return through the first six years after the financial crisis, lost their momentum amid the 2015 market weakness.

The difficulties were most apparent among oil and gas stocks, which sank 30% or more in all three funds. The sharp slide of oil prices punished the sector, in part because of high production levels

from some leading oil-producing countries and concerns about the slower growth in China, the world’s largest oil importer. Companies engaged in production and exploration and services and distribution all suffered.

Commodity prices also fell, hurting stocks in the funds’ basic materials sector, including metals and mining, forestry and paper, and chemical businesses. Results were also negative in the consumer goods, consumer services, industrials, and telecommunications sectors, although the declines weren’t always as glaring.

Health care and technology, two traditional growth-oriented sectors, led returns for the Small-Cap Index Fund and the Growth Index Fund. Long-term demographic and economic trends continue to propel health care stocks, and merger-and-acquisition activity and robust drug pipelines also lent a boost. Still, returns for the sector didn’t compare with those of recent years, as the lofty valuations of biotechnology stocks and controversy over high drug prices rattled investors at times.

Technology stocks produced muted gains, but results fluctuated across the sector’s business segments. Leaders

included software and service firms that differentiated themselves in the marketplace, delivered innovative products and solutions, and capitalized on the continued shift to mobile and cloud computing.

Financials, the largest sector for all three funds, reflected the overall sluggishness that enveloped both the broader and small-cap markets. Banks—which stand to benefit from the increase in short-term interest rates—and insurance companies carried the sector; asset managers, consumer finance firms, and mortgage companies had a rougher time.

Vanguard’s outlook for investors: Not bearish, but cautious

In Vanguard’s recently published global economic and investment outlook, Global Chief Economist Joseph Davis and his team discuss various market and economic events 2016 may bring, along with challenges and opportunities for investors.

Our forecast includes “frustratingly fragile” economic growth and more modest long-term returns from the global stock and bond markets. The report cautions that for the decade ending 2025, returns for a balanced portfolio are likely to be moderately below historical averages.

Our simulations indicate that the average annualized returns of a 60% equity/40% bond portfolio for the decade are most likely to be centered in the 3%–5% range after inflation, below the actual average after-inflation return of 5.5% for the same portfolio since 1926.

Even so, Vanguard’s steadfast belief in its principles for investing success—focusing on clear goals, a suitable asset allocation, low costs, and long-term discipline—remains unchanged.

Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.

All three small-cap index funds tightly tracked their benchmarks
For the decade ended December 31, 2015, each of the three small-cap index funds generated an average annual return of more than 7%. Most important, all three funds met their primary objective of tightly tracking their benchmark returns over a volatile period that included the worst bear market in 75 years and the subsequent recovery.

Index tracking may appear simple from the outside, but it requires sophisticated trading and portfolio construction techniques. The funds’ success in tracking their indexes is a testament to the expertise and experience of their advisor, Vanguard Equity Index Group.

Additionally, over the decade, all three funds topped the average annual returns of their peer funds, many of which are

actively managed. The Small-Cap Index Fund’s return was 2 percentage points ahead of its peer average, and the other two funds surpassed their peers by more than 1 percentage point.

To reach your long-term goals, be realistic and try to save more
Although there have been times when it felt as if stocks and bonds were riding a roller coaster, the markets have generally risen in recent years. The broad global stock market in particular has posted some impressive gains since its turnaround began in 2009.

But 2015 served as a reminder that markets aren’t always favorable. The U.S. stock and bond markets were barely positive, and international stocks and unhedged bonds finished in the red.

IMPORTANT: The projections or 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. 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 primary investment research and advice teams. 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 VCMM 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 from as early as 1960. 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.

In Vanguard’s recently updated long-term look at the economy and markets, our global economists explain why they expect economic growth to remain “frustratingly fragile,” and why their outlook for stock and bond markets is the most guarded since 2006. (For more details, see the box on page 8 and Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.)

Given these muted expectations, what’s the best course of action? I’ve often encouraged shareholders to focus on the things they can control. That advice holds true today.

Consider saving more than you think you may need. That’s one way you can prepare for the volatility that may lie ahead, particularly as markets adjust to changes in policies from the Fed and other central banks.

And, as always, investors would be well-
served to follow Vanguard’s principles
for investing success:

• Goals. Create clear, appropriate investment goals.

• Balance. Develop a suitable asset allocation using broadly diversified funds.

• Cost. Minimize cost.

• Discipline. Maintain perspective and long-term discipline.

As with saving, each of these principles is within your control, and focusing on them can keep you on the right path.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

Chairman and Chief Executive Officer

Small-Cap Index Fund

Notes to Financial Statements

Vanguard Small-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, ETF Shares, Admiral Shares, Institutional Shares, and Institutional Plus 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, Institutional Shares, and Institutional Plus Shares are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

27

Small-Cap Index Fund

During the year ended December 31, 2015, 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.

3. Swap Contracts: The fund has entered into equity swap contracts to earn the total return on selected reference stocks in the fund’s target index. Under the terms of the swaps, the fund receives the total return on the referenced stock (i.e., receiving the increase or paying the decrease in value of the selected reference stock and receiving the equivalent of any dividends in respect of the selected referenced stock) over a specified period of time, applied to a notional amount that represents the value of a designated number of shares of the selected reference stock at the beginning of the equity swap contract. The fund also pays a floating rate that is based on short-term interest rates, applied to the notional amount. At the same time, the fund invests an amount approximating the notional amount of the swap in high-quality temporary cash investments.

The notional amounts of swap contracts are not recorded in the Statement of Net Assets. Swaps are valued daily based on market quotations received from independent pricing services or recognized dealers and the change in value is recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until termination of the swap, at which time realized gain (loss) is recorded. A risk associated with all types of swaps is the possibility that a counterparty may default on its obligation to pay net amounts due to the fund. The fund’s maximum amount subject to counterparty risk is the unrealized appreciation on the swap contract. The fund mitigates its counterparty risk by entering into swaps only with a diverse group of prequalified counterparties, monitoring their financial strength, entering into master netting arrangements with its counterparties, and requiring its counterparties to transfer collateral as security for their performance. In the event of a counterparty’s default (including bankruptcy), the fund may terminate any swap contracts with that counterparty, determine the net amount owed by either party in accordance with its master netting arrangements, and sell or retain any collateral held up to the net amount owed to the fund under the master netting arrangements. The swap contracts contain provisions whereby a counterparty may terminate open contracts if the fund net assets decline below a certain level, triggering a payment by the fund if the fund is in a net liability position at the time of the termination. The payment amount would be reduced by any collateral the fund has pledged. Any securities pledged as collateral for open contracts are noted in the Statement of Net Assets. The value of collateral received or pledged is compared daily to the value of the swap contracts exposure with each counterparty, and any difference, if in excess of a specified minimum transfer amount, is adjusted and settled within two business days.

During the year ended December 31, 2015, the fund’s average amounts of investments in total return swaps represented less than 1% of net assets, based on the average of notional amounts at each quarter-end during the period.

4. 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, 2012–2015), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

28

Small-Cap Index Fund

6. 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.

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, or at any time during the period then ended.

8. 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.

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.

Small-Cap Index Fund

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, 2015, the fund had contributed to Vanguard capital in the amount of $4,862,000, representing 0.01% of the fund’s net assets and 1.94% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	53,677,439	—	2,366
Temporary Cash Investments	1,171,604	12,600	—

D. At December 31, 2015, 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 Russell 2000 Index	March 2016	1,611	182,285	1,985
E-mini S&P MidCap 400 Index	March 2016	225	31,354	146
				2,131

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

At December 31, 2015, the fund had the following open total return swap contracts:

				Floating	Unrealized
			Notional	Interest Rate	Appreciation
	Termination		Amount	Received	(Depreciation)
Reference Entity	Date	Counterparty	($000)	(Paid)	($000)
Ambac Financial Group Inc.	1/11/16	GSBUSA	3,252	(0.693%)	(26)
Empire State Realty Trust Inc.	2/17/16	GSBUSA	12,207	(0.695%)	388
SLM Corp.	3/24/16	GSI	29,302	(0.818%)	946
					1,308
GSBUSA—Goldman Sachs Bank USA.
GSI—Goldman Sachs International.

At December 31, 2015, the counterparty had deposited in segregated accounts securities with a value of $1,462,000 in connection with amounts due to the fund for open swap contracts.

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.

Certain of the fund’s investments are in securities considered to be passive foreign investment companies, for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2015, the fund realized gains on the sale of passive foreign investment companies of $335,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to overdistributed net investment income. Passive foreign investment companies held at December 31, 2015, had unrealized appreciation of $7,784,000, all of which has been distributed and is reflected in the balance of overdistributed net investment income.

31

Small-Cap Index Fund

During the year ended December 31, 2015, the fund realized $3,204,238,000 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.

Realized and unrealized gains (losses) on certain of the fund’s swap contracts are treated as ordinary income (loss) for tax purposes. Realized losses of $20,006,000 on swap contracts have been reclassified from accumulated net realized losses to overdistributed net investment income.

For tax purposes, at December 31, 2015, the fund had $12,678,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $2,428,148,000 to offset future net capital gains. Of this amount, $946,157,000 is subject to expiration dates; $342,008,000 may be used to offset future net capital gains through December 31, 2017, and $604,149,000 through December 31, 2018. Capital losses of $1,481,991,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $47,048,070,000. Net unrealized appreciation of investment securities for tax purposes was $7,815,939,000, consisting of unrealized gains of $12,587,003,000 on securities that had risen in value since their purchase and $4,771,064,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $18,555,526,000 of investment securities and sold $12,142,217,000 of investment securities, other than temporary cash investments. Purchases and sales include $8,511,788,000 and $6,363,001,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

G. Capital share transactions for each class of shares were:

Small-Cap Growth Index Fund

Notes to Financial Statements

Vanguard Small-Cap Growth 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 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 Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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, 2015, 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.

49

Small-Cap Growth Index Fund

3. Swap Contracts: The fund has entered into equity swap contracts to earn the total return on selected reference stocks in the fund’s target index. Under the terms of the swaps, the fund receives the total return on the referenced stock (i.e., receiving the increase or paying the decrease in value of the selected reference stock and receiving the equivalent of any dividends in respect of the selected referenced stock) over a specified period of time, applied to a notional amount that represents the value of a designated number of shares of the selected reference stock at the beginning of the equity swap contract. The fund also pays a floating rate that is based on short-term interest rates, applied to the notional amount. At the same time, the fund invests an amount approximating the notional amount of the swap in high-quality temporary cash investments.

The notional amounts of swap contracts are not recorded in the Statement of Net Assets. Swaps are valued daily based on market quotations received from independent pricing services or recognized dealers and the change in value is recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until termination of the swap, at which time realized gain (loss) is recorded. A risk associated with all types of swaps is the possibility that a counterparty may default on its obligation to pay net amounts due to the fund. The fund’s maximum amount subject to counterparty risk is the unrealized appreciation on the swap contract. The fund mitigates its counterparty risk by entering into swaps only with a diverse group of prequalified counterparties, monitoring their financial strength, entering into master netting arrangements with its counterparties, and requiring its counterparties to transfer collateral as security for their performance. In the event of a counterparty’s default (including bankruptcy), the fund may terminate any swap contracts with that counterparty, determine the net amount owed by either party in accordance with its master netting arrangements, and sell or retain any collateral held up to the net amount owed to the fund under the master netting arrangements. The swap contracts contain provisions whereby a counterparty may terminate open contracts if the fund net assets decline below a certain level, triggering a payment by the fund if the fund is in a net liability position at the time of the termination. The payment amount would be reduced by any collateral the fund has pledged. Any securities pledged as collateral for open contracts are noted in the Statement of Net Assets. The value of collateral received or pledged is compared daily to the value of the swap contracts exposure with each counterparty, and any difference, if in excess of a specified minimum transfer amount, is adjusted and settled within two business days.

During the year ended December 31, 2015, the fund’s average amounts of investments in total return swaps represented less than 1% of net assets, based on the average of notional amounts at each quarter-end during the period. The fund had no open swap contracts at December 31, 2015.

4. 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, 2012–2015), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

6. 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

50

Small-Cap Growth Index Fund

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.

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, or at any time during the period then ended.

8. 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.

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.

51

Small-Cap Growth Index Fund

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At December 31, 2015, the fund had contributed to Vanguard capital in the amount of $1,358,000, representing 0.01% of the fund’s net assets and 0.54% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	15,111,166	—	—
Temporary Cash Investments	408,782	3,197	—
Futures Contracts—Assets1	138	—	—
Futures Contracts—Liabilities1	(591)	—	—
Total	15,519,495	3,197	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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 Russell 2000 Index	March 2016	273	30,890	655
E-mini S&P 500 Index	March 2016	10	1,018	21
				676

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

52

Small-Cap Growth Index Fund

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, 2015, the fund realized $1,462,463,000 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.

Realized and unrealized gains (losses) on certain of the fund’s swap contracts are treated as ordinary income (loss) for tax purposes. Realized losses of $455,000 on swap contracts have been reclassified from accumulated net realized losses to undistributed net investment income.

For tax purposes, at December 31, 2015, the fund had $5,089,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $1,179,420,000 to offset future net capital gains. Of this amount, $504,200,000 is subject to expiration dates; $243,082,000 may be used to offset future net capital gains through December 31, 2017 and $261,118,000 through December 31, 2018. Capital losses of $675,220,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $13,360,136,000. Net unrealized appreciation of investment securities for tax purposes was $2,163,009,000, consisting of unrealized gains of $3,447,782,000 on securities that had risen in value since their purchase and $1,284,773,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $7,238,163,000 of investment securities and sold $6,790,814,000 of investment securities, other than temporary cash investments. Purchases and sales include $3,168,337,000 and $3,171,729,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Small-Cap Value Index Fund

Notes to Financial Statements

Vanguard Small-Cap Value 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 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 Shares are designed for investors who meet certain administrative, service, and account-size criteria

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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, 2015, 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.

3. Swap Contracts: The fund has entered into equity swap contracts to earn the total return on selected reference stocks in the fund’s target index. Under the terms of the swaps, the fund receives the total return on the referenced stock (i.e., receiving the increase or paying the decrease in value of the selected reference stock and receiving the equivalent of any dividends in respect of the selected referenced stock) over a specified period of time, applied to a notional amount that represents the value of a designated number of shares of the selected reference stock at the beginning of the equity swap contract. The fund also pays a floating rate that is based on short-term interest rates, applied to the notional amount. At the same time, the fund invests an amount approximating the notional amount of the swap in high-quality temporary cash investments.

The notional amounts of swap contracts are not recorded in the Statement of Net Assets. Swaps are valued daily based on market quotations received from independent pricing services or recognized dealers and the change in value is recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until termination of the swap, at which time realized gain (loss) is recorded. A risk associated with all types of swaps is the possibility that a counterparty may default on its obligation to pay net amounts due to the fund. The fund’s maximum amount subject to counterparty risk is the unrealized appreciation on the swap contract. The fund mitigates its counterparty risk by entering into swaps only with a diverse group of prequalified counterparties, monitoring their financial strength, entering into master netting arrangements with its counterparties, and requiring its counterparties to transfer collateral as security for their performance. In the event of a counterparty’s default (including bankruptcy), the fund may terminate any swap contracts with that counterparty, determine the net amount owed by either party in accordance with its master netting arrangements, and sell or retain any collateral held up to the net amount owed to the fund under the master netting arrangements. The swap contracts contain provisions whereby a counterparty may terminate open contracts if the fund net assets decline below a certain level, triggering a payment by the fund if the fund is in a net liability position at the time of the termination. The payment amount would be reduced by any collateral the fund has pledged. Any securities pledged as collateral for open contracts are noted in the Statement of Net Assets. The value of collateral received or pledged is compared daily to the value of the swap contracts exposure with each counterparty, and any difference, if in excess of a specified minimum transfer amount, is adjusted and settled within two business days.

During the year ended December 31, 2015, the fund’s average amounts of investments in total return swaps represented less than 1% of net assets, based on the average of notional amounts at each quarter-end during the period.

4. 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, 2012–2015), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

6. 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.

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, or at any time during the period then ended.

8. 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.

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.

72

Small-Cap Value Index Fund

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At December 31, 2015, the fund had contributed to Vanguard capital in the amount of $1,493,000, representing 0.01% of the fund’s net assets and 0.60% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	16,411,894	—	1,196
Temporary Cash Investments	246,960	3,992	—

Futures Contracts—Liabilities1	(547)	—	—
Swap Contracts—Liabilities	—	(15)	—
Total	16,658,361	3,977	1,196
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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

E-mini S&P MidCap 400 Index	March 2016	60	8,361	(77)
				(111)

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.

Certain of the fund’s investments are in securities considered to be passive foreign investment companies, for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2015, the fund realized gains on the sale of passive foreign investment companies of $280,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to overdistributed net investment income. Passive foreign investment companies held at December 31, 2015, had unrealized appreciation of $4,611,000, of which all has been distributed and is reflected in the balance of overdistributed net investment income.

During the year ended December 31, 2015, the fund realized $944,968,000 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.

Realized and unrealized gains (losses) on certain of the fund’s swap contracts are treated as ordinary income (loss) for tax purposes. Realized losses of $1,559,000 on swap contracts have been reclassified from accumulated net realized losses to overdistributed net investment income.

For tax purposes, at December 31, 2015, the fund had $2,260,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $1,229,284,000 to offset future net capital gains. Of this amount, $876,582,000 is subject to expiration dates; $487,808,000 may be used to offset future net capital gains through December 31, 2017, and $388,774,000 through December 31, 2018. Capital losses of $352,702,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $15,117,264,000. Net unrealized appreciation of investment securities for tax purposes was $1,546,778,000, consisting of unrealized gains of $2,995,062,000 on securities that had risen in value since their purchase and $1,448,284,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $7,533,085,000 of investment securities and sold $4,756,731,000 of investment securities, other than temporary cash investments. Purchases and sales include $3,370,543,000 and $2,236,124,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard Index Funds and the Shareholders of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund:

In our opinion, the accompanying statements of net assets—investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2015, 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 then ended, and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. 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, 2015 by correspondence with the custodians and brokers, by agreement to the underlying ownership records of the transfer agent and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.

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.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

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.

Institutional Shares	1,000.00	1,024.85	0.36

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Small-Cap Index Fund, 0.18% for Investor Shares, 0.09% for ETF Shares, 0.09% for Admiral Shares, 0.07% for Institutional Shares, and 0.05% for Institutional Plus Shares; for the Small-Cap Growth Index Fund, 0.20% for Investor Shares, 0.07% for ETF Shares, 0.07% for Admiral Shares, and 0.07% for Institutional Shares; and for the Small-Cap Value Index Fund, 0.20% for Investor Shares, 0.08% for ETF Shares, 0.08% for Admiral Shares, and 0.07% for Institutional 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 (184/365).

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.

82

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 194 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. 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 Letter

Dear Shareholder,

U.S. stocks registered a very small gain in 2015 amid volatility across global markets. Midsize- and small-company stocks didn’t keep pace with larger-company stocks, which represent the lion’s share of the value of the U.S. market.

In this environment, the three Vanguard Mid-Cap Index Funds delivered negative returns between –1% and –2% for the 12 months ended December 31, 2015. Vanguard Extended Market Index Fund, which includes both small- and mid-capitalization holdings, finished with a return of –3.39% (all returns cited are for Investor Shares).

All four funds covered in this report closely tracked their target indexes, and all recorded results that were ahead of the average returns of peer funds.

If you hold your fund in a taxable account, you may wish to review the after-tax returns that appear later in this report.

Despite troubles, U.S. stocks eked out a seventh year of gains

U.S. stocks returned 0.48% for the 12 months ended December 31, 2015. Although the broad market recorded its worst performance since 2008, it still posted gains for the seventh straight calendar year when dividends are factored into returns.

Stocks rose modestly over the first half of the year but slid in August and September as concerns mounted that China’s economic slowdown would spread globally. Falling oil and commodity prices also affected economies and markets across the world for better or worse. Central banks in Europe and Asia bolstered their stimulus efforts against weak growth and low inflation. And in December, the Federal Reserve ended months of uncertainty when it raised the target for short-term interest rates to 0.25%–0.5%.

International stocks returned about –5%, restrained by the U.S. dollar’s strength against many foreign currencies. Emerging markets fared the worst.

U.S. bonds ended the year with a slender advance

The broad U.S. taxable bond market gained 0.55% over the 12 months; income accounted for the modestly positive result. The yield of the 10-year Treasury note ended December at 2.30%, up from 2.19% a year earlier. (Bond prices and yields move in opposite directions.)

Investors focused on the Fed’s stance on short-term interest rates and alternately embraced or avoided safe-haven assets depending on the stock market’s strength.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –6.02%, reduced by the

dollar’s strength against many foreign currencies. Without this currency effect, returns were modestly positive.

Although the Fed raised its target for short-term interest rates in mid-December, returns for money market funds and savings accounts remained limited by the 0%–0.25% levels in place for much of the past seven years.

Smaller-company stocks lagged mid-cap stocks

The Extended Market Index Fund, which includes both mid- and small-capitalization stocks, underperformed the three Vanguard Mid-Cap Index Funds. At the same time, growth stocks did a bit better than value, causing the Mid-Cap Growth Fund to finish slightly ahead of the others. (Value stocks tend to sell at relatively low prices in relation to their earnings or book value. Growth stocks typically have higher valuations because of the earnings and revenue potential of the underlying companies.)

The performance of all four funds was hurt notably by energy-related stocks, which returned –25% or worse. The sharp slide in oil prices punished the sector, in part because of high output levels from some leading oil-producing countries and concerns about the slower growth in China, the world’s largest oil importer. Natural gas prices also dropped, though not as dramatically. The vast majority of companies engaged in exploration, production, and services suffered.

The fund expense ratios shown are from the prospectus dated April 28, 2015, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2015, the funds’ expense ratios were: for the Extended Market Index Fund, 0.22% for Investor Shares, 0.09% for ETF Shares, 0.09% for Admiral Shares, 0.07% for Institutional Shares, and 0.05% for Institutional Plus Shares; for the Mid-Cap Index Fund, 0.20% for Investor Shares, 0.08% for ETF Shares, 0.08% for Admiral Shares, 0.07% for Institutional Shares, and 0.05% for Institutional Plus Shares; for the Mid-Cap Growth Index Fund, 0.20% for Investor Shares, 0.08% for ETF Shares, and 0.08% for Admiral Shares; and for the Mid-Cap Value Index Fund, 0.20% for Investor Shares, 0.08% for ETF Shares, and 0.08% for Admiral Shares.

Stocks of companies involved in basic materials sank at least –13% in three of the four funds, as the prices of many commodities fell along with the price of oil. Metals and mining firms posted the poorest results, but chemical companies, which make up the largest subsector, also struggled. Materials stocks produced a modest gain only in the Mid-Cap Growth Index Fund, but their presence in that fund is quite small.

Among other sectors, industrials and utilities hurt performance in all four funds.

There were bright spots. Health care stocks climbed between 9% and 11% in the four funds as favorable long-term demographic and economic trends continued to lift the sector. Mid-cap biotechnology and health care equipment firms were particularly strong.

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 financial sector recorded positive returns of between 2% and 5%. Strength in REITs (real estate investment trusts) and nonlife-insurance companies more than offset losses among consumer finance firms.

Technology stocks returned 1%–2%. Good results in the communications equipment and software subsectors were partially offset by negative returns among equipment and hardware companies.

Over the decade just ended, the funds produced solid returns

For the ten years ended December 31, 2015, the average annual return was 7.64% for the Extended Market Index Fund and 7.76% for the Mid-Cap Index Fund. The two other funds were launched not quite ten years ago. The average annual return since inception was 8.00% for the Mid-Cap Growth Index Fund and 7.80% for the Mid-Cap Value Index Fund. In each case, the results exceeded the average annual returns of peers.

Vanguard’s outlook for investors: Not bearish, but cautious

In Vanguard’s recently published global economic and investment outlook, Global Chief Economist Joseph Davis and his team discuss various market and economic events 2016 may bring, along with challenges and opportunities for investors.

Our forecast includes “frustratingly fragile” economic growth and more modest long-term returns from the global stock and bond markets. The report cautions that for the decade ending 2025, returns for a balanced portfolio are likely to be moderately below historical averages.

Our simulations indicate that the average annualized returns of a 60% equity/40% bond portfolio for the decade are most likely to be centered in the 3%–5% range after inflation, below the actual average after-inflation return of 5.5% for the same portfolio since 1926.

Even so, Vanguard’s steadfast belief in its principles for investing success—focusing on clear goals, a suitable asset allocation, low costs, and long-term discipline—remains unchanged.

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

Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.

IMPORTANT: The projections or 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 VCMM, derived from 10,000 simulations for U.S. equity returns and fixed income returns. Simulations as of September 30, 2015.

All four funds have closely tracked their target indexes, thanks to the expertise of Vanguard Equity Index Group, the advisor overseeing the funds. It was helped by the funds’ low expenses—a key factor for investors looking to increase their chances of success.

To reach your long-term goals, be realistic and try to save more

Although there have been times when it felt as if stocks and bonds were riding a roller coaster, the markets have generally risen in recent years. The broad global stock market in particular has posted some impressive gains since its turnaround began in 2009.

But 2015 served as a reminder that markets aren’t always favorable. The U.S. stock and bond markets were barely positive, and international stocks and unhedged bonds finished in the red.

In Vanguard’s recently updated long-term look at the economy and markets, our global economists explain why they expect economic growth to remain “frustratingly fragile,” and why their outlook for stock and bond markets is the most guarded since 2006. (For more details, see the box on page 8 and Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.)

Given these muted expectations, what’s the best course of action? I’ve often encouraged shareholders to focus on the things they can control. That advice holds true today.

Consider saving more than you think you may need. That’s one way you can prepare for the volatility that may lie ahead, particularly as markets adjust to changes in policies from the Fed and other central banks.

IMPORTANT: The projections or 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. 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 primary investment research and advice teams. 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 VCMM 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 from as early as 1960. 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.

And, as always, investors would be well-
served to follow Vanguard’s principles for
investing success:

• Goals. Create clear, appropriate
investment goals.

• Balance. Develop a suitable asset
allocation using broadly diversified funds.

• Cost. Minimize cost.

• Discipline. Maintain perspective and
long-term discipline.

As with saving, each of these principles is within your control, and focusing on them can keep you on the right path.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Extended Market Index Fund

Notes to Financial Statements

Vanguard Extended Market Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, ETF Shares, Admiral Shares, Institutional Shares, and Institutional Plus 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, Institutional Shares, and Institutional Plus Shares are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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, 2015, 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.

27

Extended Market Index Fund

3. Swap Contracts: The fund has entered into equity swap contracts to earn the total return on selected reference stocks in the fund’s target index. Under the terms of the swaps, the fund receives the total return on the referenced stock (i.e., receiving the increase or paying the decrease in value of the selected reference stock and receiving the equivalent of any dividends in respect of the selected referenced stock) over a specified period of time, applied to a notional amount that represents the value of a designated number of shares of the selected reference stock at the beginning of the equity swap contract. The fund also pays a floating rate that is based on short-term interest rates, applied to the notional amount. At the same time, the fund invests an amount approximating the notional amount of the swap in high-quality temporary cash investments.

The notional amounts of swap contracts are not recorded in the Statement of Net Assets. Swaps are valued daily based on market quotations received from independent pricing services or recognized dealers and the change in value is recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until termination of the swap, at which time realized gain (loss) is recorded. A risk associated with all types of swaps is the possibility that a counterparty may default on its obligation to pay net amounts due to the fund.

The fund’s maximum amount subject to counterparty risk is the unrealized appreciation on the swap contract. The fund mitigates its counterparty risk by entering into swaps only with a diverse group of prequalified counterparties, monitoring their financial strength, entering into master netting arrangements with its counterparties, and requiring its counterparties to transfer collateral as security for their performance. In the event of a counterparty’s default (including bankruptcy), the fund may terminate any swap contracts with that counterparty, determine the net amount owed by either party in accordance with its master netting arrangements, and sell or retain any collateral held up to the net amount owed to the fund under the master netting arrangements. The swap contracts contain provisions whereby a counterparty may terminate open contracts if the fund net assets decline below a certain level, triggering a payment by the fund if the fund is in a net liability position at the time of the termination. The payment amount would be reduced by any collateral the fund has pledged. Any securities pledged as collateral for open contracts are noted in the Statement of Net Assets. The value of collateral received or pledged is compared daily to the value of the swap contracts exposure with each counterparty, and any difference, if in excess of a specified minimum transfer amount, is adjusted and settled within two business days.

During the year ended December 31, 2015, the fund’s average amounts of investments in total return swaps represented less than 1% of net assets, based on the average of notional amounts at each quarter-end during the period.

4. 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, 2012–2015), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

6. 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

28

Extended Market Index Fund

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.

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, or at any time during the period then ended.

8. 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.

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, 2015, the fund had contributed to Vanguard capital in the amount of $3,849,000, representing 0.01% of the fund’s net assets and 1.54% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	42,553,220	295	1,808
Temporary Cash Investments	1,041,896	11,985	—

Futures Contracts—Liabilities1	(2,128)	—	—
Swap Contracts—Liabilities	—	(14)	—
Total	43,593,646	12,266	1,808
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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 MidCap 400	March 2016	403	56,158	682
E-mini Russell 2000 Index	March 2016	245	27,722	227
				909

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

At December 31, 2015, the fund had the following open total return swap contracts:
				Floating	Unrealized
			Notional	Interest Rate	Appreciation

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.

Certain of the fund’s investments are in securities considered to be passive foreign investment companies, for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2015, the fund realized gains on the sale of passive foreign investment companies of $256,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to undistributed net investment income. Passive foreign investment companies held at December 31, 2015, had unrealized appreciation of $4,886,000, of which all has been distributed and is reflected in the balance of undistributed net investment income.

During the year ended December 31, 2015, the fund realized $2,937,851,000 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.

Realized and unrealized gains (losses) on certain of the fund’s swap contracts are treated as ordinary income (loss) for tax purposes. Realized losses of $1,668,000 on swap contracts have been reclassified from accumulated net realized losses to undistributed net investment income.

For tax purposes, at December 31, 2015, the fund had $33,477,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $524,285,000 to offset future net capital gains. Of this amount, $74,162,000 is subject to expiration dates; $49,578,000 may be used to offset future net capital gains through December 31, 2017, and $24,584,000 through December 31, 2018. Capital losses of $450,123,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $36,698,843,000. Net unrealized appreciation of investment securities for tax purposes was $6,910,361,000, consisting of unrealized gains of $11,325,084,000 on securities that had risen in value since their purchase and $4,414,723,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $12,233,513,000 of investment securities and sold $8,327,851,000 of investment securities, other than temporary cash investments. Purchases and sales include $6,659,336,000 and $5,537,163,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Performance Summary

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 than the performance data cited. For performance data current to the most recent month-end, visit our 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.

Mid-Cap Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, ETF Shares, Admiral Shares, Institutional Shares, and Institutional Plus 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, Institutional Shares, and Institutional Plus Shares are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective at the close of business on October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

51

Mid-Cap Index Fund

During the year ended December 31, 2015, 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.

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, 2012–2015), 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.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, 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.

52

Mid-Cap 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, 2015, the fund had contributed to Vanguard capital in the amount of $5,819,000, representing 0.01% of the fund’s net assets and 2.33% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	65,581,084	—	—
Temporary Cash Investments	592,394	11,084	—
Futures Contracts—Liabilities1	(1,491)	—	—
Total	66,171,987	11,084	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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 2016	900	91,593	637
E-mini S&P MidCap 400 Index	March 2016	482	67,167	910
				1,547

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, 2015, the fund realized $4,221,102,000 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, 2015, the fund had $25,830,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $1,949,337,000 to offset future net capital gains. Of this amount, $294,968,000 is subject to expiration on December 31, 2018. Capital losses of $1,654,369,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $54,847,006,000. Net unrealized appreciation of investment securities for tax purposes was $11,337,556,000, consisting of unrealized gains of $14,370,918,000 on securities that had risen in value since their purchase and $3,033,362,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $27,381,469,000 of investment securities and sold $18,531,674,000 of investment securities, other than temporary cash investments. Purchases and sales include $11,810,404,000 and $9,059,213,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Mid-Cap Growth Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers three classes of shares: Investor Shares, ETF Shares, and Admiral 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 are designed for investors who meet certain administrative, service, and account-size criteria.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

68

Mid-Cap Growth Index Fund

During the year ended December 31, 2015, 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.

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, 2012–2015), 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.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, 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.

69

Mid-Cap Growth 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, 2015, the fund had contributed to Vanguard capital in the amount of $630,000, representing 0.01% of the fund’s net assets and 0.25% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	7,140,621	—	—
Temporary Cash Investments	92,643	1,996	—

Total	7,232,989	1,996	—
1 Represents variation margin on the last day of the reporting period.

Mid-Cap Growth Index Fund

D. At December 31, 2015, 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 2016	130	13,230	(66)
E-mini S&P MidCap 400 Index	March 2016	60	8,361	101
				35

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, 2015, the fund realized $469,416,000 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, 2015, the fund had $356,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $359,917,000 to offset future net capital gains. Of this amount, $73,214,000 is subject to expiration on December 31, 2018. Capital losses of $286,703,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $6,620,842,000. Net unrealized appreciation of investment securities for tax purposes was $614,418,000, consisting of unrealized gains of $999,148,000 on securities that had risen in value since their purchase and $384,730,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $4,697,294,000 of investment securities and sold $2,892,266,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,990,050,000 and $1,360,982,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Mid-Cap Value Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers three classes of shares: Investor Shares, ETF Shares, and Admiral 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 are designed for investors who meet certain administrative, service, and account-size criteria.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

85

Mid-Cap Value Index Fund

During the year ended December 31, 2015, 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.

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, 2012–2015), 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.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, 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.

86

Mid-Cap Value 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, 2015, the fund had contributed to Vanguard capital in the amount of $772,000, representing 0.01% of the fund’s net assets and 0.31% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	8,798,836	—	—
Temporary Cash Investments	51,444	1,997	—
Futures Contracts—Liabilities1	(185)	—	—
Total	8,850,095	1,997	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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 2016	130	13,230	109
E-mini S&P MidCap 400 Index	March 2016	46	6,410	80
				189

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, 2015, the fund realized $523,500,000 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, 2015, the fund had $5,523,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $265,910,000 to offset future net capital gains. Of this amount, $4,037,000 is subject to expiration on December 31, 2018. Capital losses of $261,873,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $8,141,746,000. Net unrealized appreciation of investment securities for tax purposes was $710,531,000, consisting of unrealized gains of $1,198,629,000 on securities that had risen in value since their purchase and $488,098,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $5,278,660,000 of investment securities and sold $3,060,771,000 of investment securities, other than temporary cash investments. Purchases and sales include $2,366,767,000 and $1,447,073,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard Index Funds and the Shareholders of Vanguard Extended Market Index Fund, Vanguard Mid-Cap Index Fund, Vanguard Mid-Cap Growth Index Fund and Vanguard Mid-Cap Value Index Fund: In our opinion, the accompanying statements of net assets, statement of net assets—investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Extended Market Index Fund, Vanguard Mid-Cap Index Fund, Vanguard Mid-Cap Growth Index Fund and Vanguard Mid-Cap Value Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2015, 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 then ended, and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. 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, 2015 by correspondence with the custodians and brokers, by agreement to the underlying ownership records of the transfer agent and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.

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.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

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.

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Extended Market Index Fund, 0.23% for Investor Shares, 0.09% for ETF Shares, 0.10% for Admiral Shares, 0.08% for Institutional Shares, and 0.05% for Institutional Plus Shares; for the Mid-Cap Index Fund, 0.19% for Investor Shares, 0.09% for ETF Shares, 0.09% for Admiral Shares, 0.08% for Institutional Shares, and 0.06% for Institutional Plus Shares; for the Mid-Cap Growth Index Fund, 0.19% for Investor Shares, 0.09% for ETF Shares, and 0.08% for Admiral Shares; and for the Mid-Cap Value Index Fund, 0.19% for Investor Shares, 0.09% for ETF Shares, and 0.09% for Admiral 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 (184/365).

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.

97

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 194 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. 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 Letter

Dear Shareholder,

The year ended December 31, 2015, was a tumultuous one for the world’s financial markets. Not immune to the volatility, the broad U.S. stock market navigated a bumpy road to modest gains. Growth stocks outpaced their value counterparts, while large-capitalization stocks exceeded mid-caps and small-caps.

In this investment environment, Vanguard’s three large-capitalization U.S. index funds produced varying results. Vanguard Growth Index Fund returned 3.17%, while Vanguard Value Index Fund returned –1.03%. Vanguard Large-Cap Index Fund, which holds both growth and value stocks, returned 0.93%. (All returns are for the funds’ Investor Shares.) Each fund closely tracked its target index for the fiscal year.

If you hold any of these funds in a taxable account, you may wish to review the table of after-tax returns that appears later in this report.

Despite troubles, U.S. stocks eked out a seventh year of gains
U.S. stocks returned 0.48% for the 12 months ended December 31, 2015. Although the broad market recorded its worst performance since 2008, it still posted gains for the seventh straight calendar year when dividends are factored into returns.

Stocks rose modestly over the first half of the year but slid in August and September as concerns mounted that China’s economic slowdown would spread globally. Falling oil and commodity prices also affected economies and markets across the world for better or worse. Central banks in Europe and Asia bolstered their stimulus efforts against weak growth and low inflation. And in December, the Federal Reserve ended months of uncertainty when it raised the target for short-term interest rates to 0.25%–0.5%.

International stocks returned about –5%, restrained by the U.S. dollar’s strength against many foreign currencies. Emerging markets fared the worst.

U.S. bonds ended the year with a slender advance

The broad U.S. taxable bond market gained 0.55% over the 12 months; income accounted for the modestly positive result. The yield of the 10-year Treasury note ended December at 2.30%, up from 2.19% a year earlier. (Bond prices and yields move in opposite directions.)

Investors focused on the Fed’s stance on short-term interest rates and alternately embraced or avoided safe-haven assets depending on the stock market’s strength.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –6.02%, reduced by

the dollar’s strength against many foreign currencies. Without this currency effect, returns were modestly positive.

Although the Fed raised its target for short-term interest rates in mid-December, returns for money market funds and savings accounts remained limited by the 0%–0.25% levels in place for much of the past seven years.

Gains in some sectors were offset by energy’s double-digit decline

Vanguard’s three large-cap index funds provide exposure to some of the United States’ biggest companies. Investors can invest broadly in the large-cap market through the Large-Cap Index Fund, or focus specifically on large-cap growth or value stocks through one of the other two funds.

As I mentioned earlier, growth stocks trumped their value counterparts for the 12 months. The performance of Vanguard’s large-cap index funds mirrored this broad market trend, with the Growth Index Fund outpacing the Value Index Fund by several percentage points. Results by sector were mixed, and the performance of a few sectors varied between the funds.

For the most part the U.S. economy grew, boosted by shoppers’ overall confidence and their willingness and ability to spend. This trend benefited the consumer

The fund expense ratios shown are from the prospectus dated April 28, 2015, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2015, the funds’ expense ratios were: for the Growth Index Fund, 0.22% for Investor Shares, 0.08% for ETF Shares, 0.08% for Admiral Shares, and 0.07% for Institutional Shares; for the Value Index Fund, 0.22% for Investor Shares, 0.08% for ETF Shares, 0.08% for Admiral Shares, and 0.07% for Institutional Shares; and for the Large-Cap Index Fund, 0.20% for Investor Shares, 0.08% for ETF Shares, 0.08% for Admiral Shares, and 0.07% for Institutional Shares.

services and consumer goods sectors. Consumer services was the top performer in both the Growth Index Fund and the Large-Cap Index Fund, with internet retailers, home improvement stores, and restaurants generally leading the way. (The sector posted a negative result for the Value Index Fund.) Within the consumer goods sector, tobacco and beverage companies did very well in each of the three funds.

Gains in the information technology and health care sectors also helped the funds’ performance; however, returns for both paled compared with those seen in some recent periods. The tiny telecommunications sector also posted a positive result for each fund.

Much of the contribution made by these sectors was erased by a double-digit decline in oil and gas, which was the most significant detractor in all three funds by a wide margin. The lengthy and sharp slide of oil prices punished the sector, in part because of high production levels from some leading oil-producing countries and concerns about the slower growth in China, the world’s largest oil importer.

gas prices also dropped, though not as dramatically. Some integrated oil and gas firms held up better than others, but most production and exploration companies suffered, as did most equipment, services, and distribution companies.

Stocks in the utilities and basic materials sectors also weighed on the funds’ returns. While the performance of financials and industrials varied among the funds, the broad market results for these sectors were negative.

The funds continue to meet their long-term objectives

Over the last ten years the three large-cap index funds recorded average annual returns ranging from 6.33% for the Value Index Fund to 8.30% for the Growth Index Fund. The Large-Cap Index Fund posted an average annual return of 7.33%.

Most important, the funds have succeeded in meeting their primary objective of closely tracking their respective indexes over the long term—no easy feat during a period that

Vanguard’s outlook for investors: Not bearish, but cautious

In Vanguard’s recently published global economic and investment outlook, Global Chief

Economist Joseph Davis and his team discuss various market and economic events 2016

may bring, along with challenges and opportunities for investors.

Our forecast includes “frustratingly fragile” economic growth and more modest long-term

returns from the global stock and bond markets. The report cautions that for the decade ending

2025, returns for a balanced portfolio are likely to be moderately below historical averages.

Our simulations indicate that the average annualized returns of a 60% equity/40% bond

portfolio for the decade are most likely to be centered in the 3%–5% range after inflation,

below the actual average after-inflation return of 5.5% for the same portfolio since 1926.

Even so, Vanguard’s steadfast belief in its principles for investing success—focusing on clear

goals, a suitable asset allocation, low costs, and long-term discipline—remains unchanged.

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

Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.

IMPORTANT: The projections or 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 VCMM, derived from 10,000 simulations for U.S. equity returns and fixed income returns. Simulations as of September 30, 2015.

included the worst global recession since the Great Depression. That they did so is a tribute to the experience, talent, and sophisticated systems of their advisor, Vanguard Equity Index Group. The funds’ low expenses––which allow you to keep more of the return on your investment––have helped in these efforts.

To reach your long-term goals, be realistic and try to save more

Although there have been times when it felt as if stocks and bonds were riding a roller coaster, the markets have generally risen in recent years. The broad global stock market in particular has posted some impressive gains since its turnaround began in 2009.

But 2015 served as a reminder that markets aren’t always favorable. The U.S. stock and bond markets were basically flat, and international stocks and unhedged bonds finished in the red.

In Vanguard’s recently updated long-term look at the economy and markets, our global economists explain why they expect economic growth to remain “frustratingly fragile,” and why their outlook for stock and bond markets is the most guarded since 2006. (For more details, see the box on page 8 and Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.)

IMPORTANT: The projections or 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. 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 primary investment research and advice teams. 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 VCMM 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 from as early as 1960. 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.

Given these muted expectations, what’s the best course of action? I’ve often encouraged shareholders to focus on the things they can control. That advice holds true today.

Consider saving more than you think you may need. That’s one way you can prepare for the volatility that may lie ahead, particularly as markets adjust to changes in policies from the Fed and other central banks.

And, as always, investors would be well-served to follow Vanguard’s principles for investing success:

• Goals. Create clear, appropriate investment goals.

• Balance. Develop a suitable asset allocation using broadly diversified funds.

• Cost. Minimize cost.

• Discipline. Maintain perspective and long-term discipline.

As with saving, each of these principles is within your control, and focusing on them can keep you on the right path.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

Chairman and Chief Executive Officer

Growth Index Fund

Notes to Financial Statements

Vanguard Growth 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 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 Shares are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective at the close of business on October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

27

Growth Index Fund

During the year ended December 31, 2015, 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.

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, 2012–2015), 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.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, 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.

28

Growth 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, 2015, the fund had contributed to Vanguard capital in the amount of $4,421,000, representing 0.01% of the fund’s net assets and 1.77% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	49,873,048	—	—
Temporary Cash Investments	223,568	7,687	—
Futures Contracts—Liabilities1	(313)	—	—
Total	50,096,303	7,687	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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 2016	326	33,177	(146)

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, 2015, the fund realized $1,947,855,000 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, 2015, the fund had $16,412,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $1,036,271,000 to offset future net capital gains. Of this amount, $300,177,000 is subject to expiration on December 31, 2017. Capital losses of $736,094,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $33,457,681,000. Net unrealized appreciation of investment securities for tax purposes was $16,646,622,000, consisting of unrealized gains of $17,618,436,000 on securities that had risen in value since their purchase and $971,814,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $12,299,246,000 of investment securities and sold $8,289,624,000 of investment securities, other than temporary cash investments. Purchases and sales include $6,050,798,000 and $3,869,116,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Value Index Fund

Notes to Financial Statements

Vanguard Value 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 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 Shares are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective at the close of business on October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

48

Value Index Fund

During the year ended December 31, 2015, 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.

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, 2012–2015), 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.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, 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.

49

Value 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, 2015, the fund had contributed to Vanguard capital in the amount of $3,287,000, representing 0.01% of the fund’s net assets and 1.31% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	37,602,769	—	—
Temporary Cash Investments	60,837	5,894	—
Futures Contracts—Liabilities1	(252)	—	—
Total	37,663,354	5,894	—

Value Index Fund

D. At December 31, 2015, 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 2016	263	26,766	(71)

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, 2015, the fund realized $1,249,696,000 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, 2015, the fund had $9,688,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $605,415,000 to offset future net capital gains. Of this amount, $333,377,000 is subject to expiration on December 31, 2017. Capital losses of $272,038,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $32,338,864,000. Net unrealized appreciation of investment securities for tax purposes was $5,330,636,000, consisting of unrealized gains of $6,945,089,000 on securities that had risen in value since their purchase and $1,614,453,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $9,128,409,000 of investment securities and sold $6,583,495,000 of investment securities, other than temporary cash investments. Purchases and sales include $4,736,551,000 and $3,671,355,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Large-Cap Index Fund

Notes to Financial Statements

Vanguard Large-Cap 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 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 Shares are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective at the close of business on October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

72

Large-Cap Index Fund

During the year ended December 31, 2015, 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.

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, 2012–2015), 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.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, 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.

73

Large-Cap 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, 2015, the fund had contributed to Vanguard capital in the amount of $977,000, representing 0.01% of the fund’s net assets and 0.39% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	11,128,914	—	—
Temporary Cash Investments	43,923	2,497	—
Futures Contracts—Liabilities1	(300)	—	—
Total	11,172,537	2,497	—
1 Represents variation margin on the last day of the reporting period.

Large-Cap Index Fund

D. At December 31, 2015, 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 2016	313	31,854	375

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, 2015, the fund realized $219,948,000 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, 2015, the fund had $3,287,000 of ordinary income available for distribution. At December 31, 2015, the fund had available capital losses totaling $77,696,000 to offset future net capital gains. Of this amount, $24,177,000 is subject to expiration on December 31, 2018. Capital losses of $53,519,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At December 31, 2015, the cost of investment securities for tax purposes was $7,952,205,000. Net unrealized appreciation of investment securities for tax purposes was $3,223,129,000, consisting of unrealized gains of $3,518,049,000 on securities that had risen in value since their purchase and $294,920,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $2,085,703,000 of investment securities and sold $810,296,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,211,483,000 and $385,107,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard Index Funds and the Shareholders of Vanguard Growth Index Fund, Vanguard Value Index Fund and Vanguard Large-Cap Index Fund:

In our opinion, the accompanying statements of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Growth Index Fund, Vanguard Value Index Fund and Vanguard Large-Cap Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2015, 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 then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. 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, 2015 by correspondence with the custodians and brokers, by agreement to the underlying ownership records of the transfer agent and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.

The funds distributed qualified dividend income to shareholders during the fiscal year as follows:

Fund	($000)
Growth Index Fund	596,225
Value Index Fund	963,790
Large-Cap Index Fund	208,069

For corporate shareholders, the percentage of investment income (dividend income plus short-term gains, if any) that qualifies for the dividends-received deduction is as follows:

Fund	Percentage
Growth Index Fund	89.1%

Large-Cap Index Fund	95.5

78

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.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

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.

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Growth Index Fund, 0.23% for Investor Shares, 0.09% for ETF Shares, 0.09% for Admiral Shares, and 0.07% for Institutional Shares; for the Value Index Fund, 0.23% for Investor Shares, 0.09% for ETF Shares, 0.09% for Admiral Shares, and 0.08% for Institutional Shares; and for the Large-Cap Index Fund, 0.18% for Investor Shares, 0.09% for ETF Shares, 0.09% for Admiral Shares, and 0.08% for Institutional 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 (184/365).

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.

83

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 194 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. 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 Letter

Dear Shareholder,

Buffeted by various global economic and market challenges, U.S. stocks traced a roundabout route in 2015 before finishing slightly ahead of where they started. Over the 12-month period ended December 31, 2015, Vanguard Total Stock Market Index Fund’s Investor Shares returned 0.29%. The fund closely tracked the performance of its benchmark, the CRSP US Total Market Index, and surpassed the average return of its multi-cap core fund peers by about 2 percentage points.

Growth stocks outpaced their value counterparts, and large-capitalization stocks exceeded mid-caps and small-caps. Six of the market’s ten industry sectors posted positive results. Consumer and health care stocks were the top performers, while oil and gas and basic materials stocks noticeably lagged.

A broad stock market index fund can be a tax-efficient investment. If you hold the fund in a taxable account, you may wish to review the after-tax returns that appear later in this report.

Despite troubles, U.S. stocks eked out a seventh year of gains
U.S. stocks returned 0.48% for the 12 months. Although the broad market recorded its worst performance since 2008, it still posted gains for the seventh straight calendar year when dividends are factored into returns.

2

Stocks rose modestly over the first half of the year but slid in August and September as concerns mounted that China’s economic slowdown would spread globally. Falling oil and commodity prices also affected economies and markets across the world for better or worse. Central banks in Europe and Asia bolstered their stimulus efforts against weak growth and low inflation. And in December, the Federal Reserve ended months of uncertainty when it raised the target for short-term interest rates to 0.25%–0.5%.

International stocks returned about –5%, restrained by the U.S. dollar’s strength against many foreign currencies. Emerging markets fared the worst.

U.S. bonds ended the year with a slender advance

The broad U.S. taxable bond market gained 0.55% over the 12 months; income accounted for the modestly positive result. The yield of the 10-year Treasury note ended December at 2.30%, up from 2.19% a year earlier. (Bond prices and yields move in opposite directions.)

Investors focused on the Fed’s stance on short-term interest rates and alternately embraced or avoided safe-haven assets, depending on the stock market’s strength.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –6.02%, reduced by the

dollar’s strength against many foreign currencies. Without this currency effect, returns were modestly positive.

Although the Fed raised its target for short-term interest rates in mid-December, returns for money market funds and savings accounts remained limited by the 0%–0.25% levels in place for much of the past seven years.

Oil and gas stocks’ fall continued; consumer sectors were bright spots

Vanguard Total Stock Market Index Fund offers investors exposure to every segment of the U.S. equity market. Stocks of all sizes, styles, and sectors are represented. For this period, the fund’s overall performance was helped by its heavy exposure to large-cap stocks.

The retreat of oil and gas stocks, which returned about –22% over the period, had the largest impact on the fund’s overall results. Oil prices’ lengthy and sharp slide punished the sector, in part because of high production levels from some leading oil-producing countries and the concerns about China, the world’s largest oil importer. Natural gas prices also dropped, though not as dramatically. Some integrated oil and gas firms held up better than others, but most companies engaged in production and exploration and services and distribution suffered.

The basic materials sector, which returned –12%, was another of the broad market’s weakest as commodity prices fell along with those of oil. Metals and mining firms, which dominate the sector, posted the

The fund expense ratios shown are from the prospectus dated April 28, 2015, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2015, the fund’s expense ratios were: 0.16% for Investor Shares, 0.05% for ETF Shares, 0.05% for Admiral Shares, 0.04% for Institutional Shares, and 0.02% for Institutional Plus Shares (annualized since inception).

poorest results, but chemical companies also struggled. The industrial and utilities sectors also declined, although not as severely as oil and gas and materials.

The investment environment wasn’t all grim. The U.S. economy mostly grew, propped up by shoppers’ overall confidence and willingness to spend. Among the market’s strongest sectors were consumer services and consumer goods. In consumer services, the internet retail area was especially productive; several home improvement retailers also excelled. In consumer goods, notable showings came from toy, tobacco, and beverage companies.

Health care stocks climbed nearly 7%, results that were a fraction better than those of consumer services and the best of the ten sectors. Merger-and-acquisition activity, vibrant drug pipelines, and favorable long-term demographic and economic trends lifted the sector, but there were stumbles related to controversy over high drug prices and lofty valuations of biotechnology stocks.

Technology returned almost 4%. As with health care, results paled compared with some robust recent periods but were still positive. Gains from internet and software firms were partially offset by poorer performance from computer hardware and semiconductor companies.

For performance data current to the most recent month-end, visit our 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 financial sector, the fund’s largest, mirrored the broader market’s return with a result that was barely positive. Real estate investment trusts (REITs) and banks managed to produce small returns, while asset managers and life insurance companies declined.

Tight tracking is evident over the previous decade

Over the last ten years, the Total Stock Market Index Fund’s Investor Shares have produced an average annual return of 7.39%, in line with the benchmark and more than 1 percentage point higher than peer funds, many of which are actively managed.

First and foremost, the fund’s objective is to track the index closely, and its success in doing so is a testament to the expertise and experience of the fund’s advisor, Vanguard Equity Index Group.

This group of professionals uses well-honed portfolio construction and trading methodologies that have allowed Vanguard to provide effective index-tracking regardless of the market’s volatility or direction.

Vanguard’s outlook for investors: Not bearish, but cautious

In Vanguard’s recently published global economic and investment outlook, Global Chief

Economist Joseph Davis and his team discuss various market and economic events 2016

may bring, along with challenges and opportunities for investors.

Our forecast includes “frustratingly fragile” economic growth and more modest long-term

returns from the global stock and bond markets. The report cautions that for the decade ending

2025, returns for a balanced portfolio are likely to be moderately below historical averages.

Our simulations indicate that the average annualized returns of a 60% equity/40% bond

portfolio for the decade are most likely to be centered in the 3%–5% range after inflation,

below the actual average after-inflation return of 5.5% for the same portfolio since 1926.

Even so, Vanguard’s steadfast belief in its principles for investing success—focusing on clear

goals, a suitable asset allocation, low costs, and long-term discipline—remains unchanged.

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

Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.

IMPORTANT: The projections or 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 VCMM, derived from 10,000 simulations for U.S. equity returns and fixed income returns. Simulations as of September 30, 2015. Results from the model may vary with each use and over time. For more information, please see page 7.

The fund has also benefited from its low costs, which help close the gap between the index’s results and yours.

To reach your long-term goals, be realistic and try to save more

Although there have been times when it felt as if stocks and bonds were riding a roller coaster, the markets have generally risen in recent years. The broad global stock market in particular has posted some impressive gains since its turnaround began in 2009.

But 2015 served as a reminder that markets aren’t always favorable. The U.S. stock and bond markets were barely positive, and international stocks and unhedged bonds finished in the red.

In Vanguard’s recently updated long-term look at the economy and markets, our global economists explain why they expect economic growth to remain “frustratingly fragile” and why their outlook for stock and bond markets is the most guarded since 2006. (For more details, see the box on page 6 and Vanguard’s Economic and Investment Outlook, available at vanguard. com/research.)

Given these muted expectations, what’s the best course of action? I’ve often encouraged shareholders to focus on the things they can control. That advice holds true today.

Consider saving more than you think you may need. That’s one way you can prepare for the volatility that may lie ahead,

IMPORTANT: The projections or 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. 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 primary investment research and advice teams. 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 VCMM 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 from as early as 1960. 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.

particularly as markets adjust to changes in policies from the Fed and other central banks.

And, as always, investors would be well-served to follow Vanguard’s principles for investing success:

• Goals. Create clear, appropriate investment goals.

• Balance. Develop a suitable asset allocation using broadly diversified funds.

• Cost. Minimize cost.

• Discipline. Maintain perspective and long-term discipline.

As with saving, each of these principles is within your control, and focusing on them can keep you on the right path.

As always, thank you for investing with Vanguard.

Sincerely,

Total Stock Market Index Fund

Notes to Financial Statements

Vanguard Total Stock Market Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, ETF Shares, Admiral Shares, Institutional Shares, and Institutional Plus 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, Institutional Shares, and Institutional Plus Shares are designed for investors who meet certain administrative, service, and account-size criteria. Prior to October 24, 2014, the fund offered Signal Shares. Effective October 24, 2014, the Signal Shares were converted to Admiral Shares.

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 acquired over 60 days to maturity 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. Other temporary cash investments are valued at amortized cost, which approximates market value.

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).

24

Total Stock Market Index Fund

During the year ended December 31, 2015, 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.

3. Swap Contracts: The fund has entered into equity swap contracts to earn the total return on selected reference stocks in the fund’s target index. Under the terms of the swaps, the fund receives the total return on the referenced stock (i.e., receiving the increase or paying the decrease in value of the selected reference stock and receiving the equivalent of any dividends in respect of the selected referenced stock) over a specified period of time, applied to a notional amount that represents the value of a designated number of shares of the selected reference stock at the beginning of the equity swap contract. The fund also pays a floating rate that is based on short-term interest rates, applied to the notional amount. At the same time, the fund invests an amount approximating the notional amount of the swap in high-quality temporary cash investments.

The notional amounts of swap contracts are not recorded in the Statement of Net Assets. Swaps are valued daily based on market quotations received from independent pricing services or recognized dealers and the change in value is recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until termination of the swap, at which time realized gain (loss) is recorded. A risk associated with all types of swaps is the possibility that a counterparty may default on its obligation to pay net amounts due to the fund. The fund’s maximum amount subject to counterparty risk is the unrealized appreciation on the swap contract. The fund mitigates its counterparty risk by entering into swaps only with a diverse group of prequalified counterparties, monitoring their financial strength, entering into master netting arrangements with its counterparties, and requiring its counterparties to transfer collateral as security for their performance. In the event of a counterparty’s default (including bankruptcy), the fund may terminate any swap contracts with that counterparty, determine the net amount owed by either party in accordance with its master netting arrangements, and sell or retain any collateral held up to the net amount owed to the fund under the master netting arrangements. The swap contracts contain provisions whereby a counterparty may terminate open contracts if the fund net assets decline below a certain level, triggering a payment by the fund if the fund is in a net liability position at the time of the termination. The payment amount would be reduced by any collateral the fund has pledged. Any securities pledged as collateral for open contracts are noted in the Statement of Net Assets. The value of collateral received or pledged is compared daily to the value of the swap contracts exposure with each counterparty, and any difference, if in excess of a specified minimum transfer amount, is adjusted and settled within two business days.

During the year ended December 31, 2015, the fund’s average amounts of investments in total return swaps represented less than 1% of net assets, based on the average of notional amounts at each quarter-end during the period.

4. 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, 2012–2015), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

6. 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.

25

Total Stock Market Index Fund

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.

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $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 0.06% 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 equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2015, or at any time during the period then ended.

8. 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.

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.

26

Total Stock Market Index Fund

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At December 31, 2015, the fund had contributed to Vanguard capital in the amount of $35,094,000, representing 0.01% of the fund’s net assets and 14.04% 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, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	398,102,532	35	2,997

Total	402,803,622	154,776	2,997
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2015, 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 2016	22,960	2,336,639	23,731

E-mini S&P MidCap 400 Index	March 2016	240	33,444	407
				26,225

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

27

Total Stock Market Index Fund

At December 31, 2015, the fund had the following open total return swap contracts:

				Floating	Unrealized
			Notional	Interest Rate	Appreciation
	Termination		Amount	Received	(Depreciation)
Reference Entity	Date	Counterparty	($000)	(Paid)	($000)
Ambac Financial Group Inc.	1/11/16	GSBUSA	3,252	(0.693%)	(27)
Empire State Realty Trust Inc.	2/17/16	GSBUSA	12,190	(0.695%)	388
SLM Corp.	3/21/16	GSI	28,910	(0.802%)	(992)
					(631)
GSBUSA—Goldman Sachs Bank USA.
GSI—Goldman Sachs International.

At December 31, 2015, the counterparty had deposited in segregated accounts securities with a value of $547,000 in connection with amounts due to the fund for open swap contracts.

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.

Certain of the fund’s investments are in securities considered to be passive foreign investment companies, for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2015, the fund realized gains on the sale of passive foreign investment companies of $18,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to overdistributed net investment income. Passive foreign investment companies held at December 31, 2015, had unrealized appreciation of $8,922,000, all of which has been distributed and is reflected in the balance of overdistributed net investment income.

During the year ended December 31, 2015, the fund realized $11,693,991,000 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.

Realized and unrealized gains (losses) on certain of the fund’s swap contracts are treated as ordinary income (loss) for tax purposes. Realized losses of $16,047,000 on swap contracts have been reclassified from accumulated net realized losses to overdistributed net investment income.

For tax purposes, at December 31, 2015, the fund had $118,094,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $917,767,000 to offset taxable capital gains realized during the year ended December 31, 2015. At December 31, 2015, the fund had available capital losses totaling $1,270,736,000 to offset future net capital gains. Of this amount, $1,003,435,000 is subject to expiration on December 31, 2016. Capital losses of $267,301,000 realized beginning in fiscal 2011 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

28

Total Stock Market Index Fund

At December 31, 2015, the cost of investment securities for tax purposes was $290,340,198,000. Net unrealized appreciation of investment securities for tax purposes was $112,650,200,000, consisting of unrealized gains of $129,321,634,000 on securities that had risen in value since their purchase and $16,671,434,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2015, the fund purchased $55,913,069,000 of investment securities and sold $32,374,141,000 of investment securities, other than temporary cash investments. Purchases and sales include $16,876,036,000 and $18,635,547,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard Index Funds and the Shareholders of Vanguard Total Stock Market Index Fund: In our opinion, the accompanying statement of net assets—investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Total Stock Market Index Fund (constituting a separate portfolio of Vanguard Index Funds, hereafter referred to as the “Fund”) at December 31, 2015, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. 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, 2015 by correspondence with the custodian and brokers, by agreement to the underlying ownership records of the transfer agent and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.

Special 2015 tax information (unaudited) for Vanguard Total Stock Market Index Fund

This information for the fiscal year ended December 31, 2015, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $7,651,494,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 90.5% of investment income (dividend income plus short-term gains, if any) qualifies for the dividends-received deduction.

31

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.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.) 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.

Six Months Ended December 31, 2015
	Beginning	Ending	Expenses

Institutional Shares	1,000.00	1,025.00	0.20
Institutional Plus Shares	1,000.00	1,025.10	0.10

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 0.17% for Investor Shares, 0.05% for ETF Shares, 0.05% for Admiral Shares, 0.04% for Institutional Shares, and 0.02% for Institutional Plus 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 (184/365).

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.

35

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 194 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. 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.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard Index Funds and the Shareholders of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund:

In our opinion, the accompanying statements of net assets – investments summary and the related statements of operations and of changes in net assets and the financial highlights (included in Item 1 of this Form N-CSR) and the schedules of investments (included in Item 6 of this Form N-CSR) present fairly, in all material respects, the financial position of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2015, 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 then ended, and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements, financial highlights, and schedules of investments (hereafter referred to as "financial statements") are the responsibility of the Funds’ management. 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, 2015 by correspondence with the custodians and brokers, by agreement to the underlying ownership records of the transfer agent and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.
