Your Fund’s Performance at a Glance

• U.S. stocks hit record highs in 2017 as investors welcomed tax legislation, strong corporate profits, low unemployment, and solid economic growth.

• In this environment, Vanguard 500 Index Fund returned nearly 22% for the 12 months ended December 31, 2017, closely tracking its target index, the Standard & Poor’s 500 Index. The fund, which provides exposure to the stocks of the largest U.S. companies, outpaced the average return of peer funds.

• Among sectors, information technology, health care, and financial stocks were strong performers. Telecommunication services and energy stocks notched modestly negative returns.

• For the ten years ended December 31, the 500 Index Fund recorded an average annual return of 8.37% for Investor Shares, closely tracking its target index. The fund’s return was more than a percentage point better than the average annual return of peer funds.

Admiral Shares carry lower expenses and are available to investors who meet certain account-balance requirements. Institutional Select
Shares are available to certain institutional investors who meet specific administrative, service, and account-size criteria. The Vanguard
ETF® Shares shown are traded on the NYSE Arca exchange and are available only through brokers. The table provides ETF returns based
on both the NYSE Arca market price and the net asset value for a share. U.S. Pat. Nos. 6,879,964; 7,337,138; 7,720,749; 7,925,573;
8,090,646; and 8,417,623.
For the ETF Shares, the market price is determined by the midpoint of the bid-offer spread as of the closing time of the New York Stock
Exchange (generally 4 p.m., Eastern time). The net asset value is also determined as of the NYSE closing time. For more information about
how the ETF Shares' market prices have compared with their net asset value, visit vanguard.com, select your ETF, and then select the
Price and Performance tab. The ETF premium/discount analysis there shows the percentages of days on which the ETF Shares' market
price was above or below the NAV.

Chairman’s Perspective

Bill McNabb
Chairman

Dear Shareholder,

Lately I’ve been asked a lot about my legacy. And candidly, that phrase bugs me—it isn’t my legacy. Vanguard’s success is a result of thousands of my colleagues committing to a clear mission: helping investors achieve their financial goals.

The reason the topic has come up is that on December 31, 2017, I officially stepped down as Vanguard’s CEO after almost a decade in that role. I’ll remain chairman for a period to be determined by the board of directors. Tim Buckley, who was previously Vanguard’s president and chief investment officer, was elected CEO. I can’t think of a better successor.

I’ve spent 32 years at Vanguard—almost my entire professional life—and during that time I’ve had the good fortune of working with smart, principled colleagues from across the world. I’ve learned from each of them.

In particular, I would like to thank Jack Bogle, our founder, who took a chance on me when I was a young business school graduate, and Jack Brennan, my predecessor as CEO, who constantly challenged me with new roles and responsibilities.

When you’re just starting out, there is nothing quite like getting votes of confidence from people you respect.

The short list

A milestone like this naturally brings about some reflection. With that in mind, here’s a tally—by no means exhaustive—of the accomplishments that we at Vanguard are proud of:

Low costs. Over the last decade, we cut our average asset-weighted expense ratio by about 50%.¹This isn’t a result of some contrived price war. Since its founding, Vanguard has emphasized the benefits of low-cost investing. As Jack Bogle once said: “The honest steward who charges least, wins most. But not for himself; for those investors who entrust their assets to his care. It is not all that complicated.”

Global diversification. Through our thought leadership and investment options, such as our target-date funds, Vanguard has encouraged clients to obtain exposure to international markets.

Global diversification isn’t just about helping to control risk—it can also be a way of expanding your set of opportunities and harnessing the potential of all markets.

1 Source: Vanguard calculation, based on data from Morningstar, Inc., as of December 31, 2016.

I’ve been glad to see more and more clients embracing global diversification. I believe this trend will continue as Vanguard’s way of investing takes hold in international markets.

Affordable advice. In the wake of the 2008–2009 Global Financial Crisis, we began working on a new advice model. In 2015, we launched Vanguard Personal Advisor Services^®, a hybrid advice offering that delivers value through a combination of a professional advisor and powerful digital technology at a competitive price.

Across the industry, we’ve seen the cost of providing advice coming down. Traditional advisors are embracing low-cost investments, and that, in turn, helps them reduce costs for their own clients. This is a trend that all of us at Vanguard would like to see continue.

Great people. I’ve interacted with hundreds of companies of all sizes and in all industries, and the one quality that sets Vanguard apart from most of them is our emphasis on people. It’s a testament to our culture that colleagues spend 15, 20, or, as in my case, more than 30 years of their professional lives here. Investors benefit because we have consistent, experienced fund management teams and a deep bench of talent that ensures that things go smoothly when it’s time for a transition.

We’ve done a great job attracting new talent, too. We made some notable additions to senior management in the last two years, and we’re continuously grooming our next generation of leaders.

Ready for what comes next

When I was contemplating coming to work at Vanguard, I sat down with my rowing coach at his home in Philadelphia. Over cheesesteaks, he told me that the most important thing was to work for a company that had the same values I held deeply. He was like a second father to me, so I trusted his judgment at a time when I wasn’t so sure about my own. Back then, I never could have anticipated the success Vanguard would have in the coming decades.

I’m no better at predicting the future now. Vanguard has enjoyed significant growth in the last few years, and that presents its own unique set of challenges and opportunities, such as the role we’re playing in advocating for better corporate governance among companies our funds invest in. And the asset management industry is confronting significant changes brought on by technology, shifting demographics, and new regulations.

Although the future is uncertain, I’m confident that Vanguard is well-prepared to tackle whatever comes its way. And one thing I’m sure of: There are big parts of the world that would be well-served by our way of investing.

Results of Proxy Voting

At a special meeting of shareholders on November 15, 2017, fund shareholders approved the
following proposals:

Proposal 1—Elect trustees for the fund.*

The individuals listed in the table below were elected as trustees for the fund. All trustees with the exception of Ms. Mulligan, Ms. Raskin, and Mr. Buckley (each of whom already serves as a director of The Vanguard Group, Inc.) served as trustees to the funds prior to the shareholder meeting.


			Percentage
Trustee	For	Withheld	For
Mortimer J. Buckley	10,555,505,764	302,858,072	97.2%
Emerson U. Fullwood	10,550,271,249	308,092,588	97.2%

F. Joseph Loughrey	10,550,135,548	308,228,289	97.2%
Mark Loughridge	10,554,054,699	304,309,138	97.2%
Scott C. Malpass	10,546,031,165	312,332,672	97.1%
F. William McNabb III	10,544,013,615	314,350,222	97.1%
Deanna Mulligan	10,560,536,084	297,827,753	97.3%
André F. Perold	10,509,222,915	349,140,922	96.8%
Sarah Bloom Raskin	10,554,241,538	304,122,299	97.2%
Peter F. Volanakis	10,551,315,296	307,048,541	97.2%
* Results are for all funds within the same trust.

Proposal 2—Approve a manager-of-managers arrangement with third-party investment advisors.

This arrangement enables the fund to enter into and materially amend investment advisory arrangements with third-party investment advisors, subject to the approval of the fund’s board of trustees and certain conditions imposed by the Securities and Exchange Commission, while avoiding the costs and delays associated with obtaining future shareholder approval.


				Broker	Percentage
Vanguard Fund	For	Abstain	Against	Non-Votes	For
500 Index Fund	896,264,163	41,278,171	41,515,030	154,428,376	79.1%

Proposal 3—Approve a manager-of-managers arrangement with wholly owned subsidiaries of Vanguard.

This arrangement enables Vanguard or the fund to enter into and materially amend investment advisory arrangements with wholly owned subsidiaries of Vanguard, subject to the approval of the fund’s board of trustees and any conditions imposed by the Securities and Exchange Commission (SEC), while avoiding the costs and delays associated with obtaining future shareholder approval. The ability of the fund to operate in this manner is contingent upon the SEC’s approval of a pending application for an order of exemption.


				Broker	Percentage
Vanguard Fund	For	Abstain	Against	Non-Votes	For
500 Index Fund	905,109,429	39,620,007	34,327,928	154,428,376	79.9%

Fund shareholders did not approve the following proposal:

Proposal 7—Institute transparent procedures to avoid holding investments in companies that, in management’s judgment, substantially contribute to genocide or crimes against humanity, the most egregious violations of human rights. Such procedures may include time-limited engagement with problem companies if management believes that their behavior can be changed.

The trustees recommended a vote against the proposal for the following reasons: (1) Vanguard is fully compliant with all applicable U.S. laws and regulations that prohibit the investment in any company owned or controlled by the government of Sudan; (2) the addition of further investment constraints is not in fund shareholders’ best interests if those constraints are unrelated to a fund’s stated investment objective, policies, and strategies; and (3) divestment is an ineffective means to implement social change as it often puts the shares into the hands of another owner with no direct impact to the company’s capitalization.

500 Index Fund

Notes to Financial Statements

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

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. investment companies. The fund consistently follows such policies in preparing its financial statements.

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

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, 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 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 notional amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of 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).

500 Index Fund

During the year ended December 31, 2017, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on the average of the notional amounts at each quarter-end during the period.

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, 2014–2017), 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 event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2017, or at any time during the period then ended.

500 Index Fund

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.

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), shareholder reporting, and the proxy. 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, 2017, the fund had contributed to Vanguard capital in the amount of $21,206,582, representing 0.01% of the fund’s net assets and 8.48% 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). Any investments valued with significant unobservable inputs are
noted on the Statement of Net Assets.

500 Index Fund

The following table summarizes the market value of the fund’s investments as of December 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	389,658,070	—	—
Temporary Cash Investments	1,450,889	85,235	—
Futures Contracts—Liabilities¹	(5,223)	—	—
Total	391,103,736	85,235	—
1 Represents variation margin on the last day of the reporting period.

D. 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, 2017, the fund realized $6,646,264,000 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, 2017, the fund had $42,626,000 of ordinary income available for distribution. At December 31, 2017, the fund had available capital losses totaling $1,161,462,000 that may be carried forward indefinitely to offset future net capital gains.

At December 31, 2017, the cost of investment securities for tax purposes was $239,798,128,000. Net unrealized appreciation of investment securities for tax purposes was $151,396,066,000, consisting of unrealized gains of $156,408,365,000 on securities that had risen in value since their purchase and $5,012,299,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $69,295,386,000 of investment securities and sold $20,128,588,000 of investment securities, other than temporary cash investments. Purchases and sales include $43,244,268,000 and $9,714,949,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

Opinion on the Financial Statements

We have audited the accompanying statement of net assets of Vanguard 500 Index Fund (one of the funds constituting Vanguard Index Funds, referred to hereafter as the “Fund”) as of December 31, 2017, the related statement of operations for the year ended December 31, 2017, the statement of changes in net assets for each of the two years in the period ended December 31, 2017, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of December 31, 2017, 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 ended December 31, 2017 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of December 31, 2017 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits 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.

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

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

About Your Fund’s Expenses

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

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

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

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

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

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

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

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

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

	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
500 Index Fund	6/30/2017	12/31/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,113.53	$0.75
ETF Shares	1,000.00	1,114.08	0.16
Admiral Shares	1,000.00	1,114.11	0.21
Institutional Select Shares	1,000.00	1,114.29	0.05
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,024.50	$0.71

Admiral Shares	1,000.00	1,025.00	0.20
Institutional Select Shares	1,000.00	1,025.16	0.05

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.14% for Investor Shares, 0.03% for ETF Shares, 0.04% for Admiral Shares, and 0.01% for Institutional Select Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period (184/365).

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.

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 201 Vanguard funds.

Information for each trustee and executive officer of the fund appears below. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.

Chairman’s Perspective

Bill McNabb
Chairman

Dear Shareholder,

When you’re just starting out, there is nothing quite like getting votes of confidence from people you respect.

The short list

A milestone like this naturally brings about some reflection. With that in mind, here’s a tally—by no means exhaustive—of the accomplishments that we at Vanguard are proud of:

Global diversification. Through our thought leadership and investment options, such as our target-date funds, Vanguard has encouraged clients to obtain exposure to international markets.

Global diversification isn’t just about helping to control risk—it can also be a way of expanding your set of opportunities and harnessing the potential of all markets.

I’ve been glad to see more and more clients embracing global diversification. I believe this trend will continue as Vanguard’s way of investing takes hold in international markets.

We’ve done a great job attracting new talent, too. We made some notable additions to senior management in the last two years, and we’re continuously grooming our next generation of leaders.

Ready for what comes next

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.

Small-Cap 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 absence of a default, the collateral pledged or received by the fund cannot be repledged, resold, or rehypothecated. 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, 2017, 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, 2014–2017), 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.

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 event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread.

The fund had no borrowings outstanding at December 31, 2017, 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.

Small-Cap Index Fund

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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At December 31, 2017, the fund had contributed to Vanguard capital in the amount of $4,637,000, representing 0.01% of the fund’s net assets and 1.85% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

Small-Cap Index Fund

During the year ended December 31, 2017, the fund realized $3,828,095,000 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, 2017, the fund had $24,052,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $341,986,000 to offset taxable capital gains realized during the year ended December 31, 2017. At December 31, 2017, the fund had available capital losses totaling $1,770,542,000 to offset future net capital gains. Of this amount, $604,149,000 is subject to expiration on December 31, 2018. Capital losses of $1,166,393,000 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 $342,008,000 expired on December 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At December 31, 2017, the cost of investment securities for tax purposes was $63,337,888,000. Net unrealized appreciation of investment securities for tax purposes was $22,186,390,000, consisting of unrealized gains of $26,245,128,000 on securities that had risen in value since their purchase and $4,058,738,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $22,438,481,000 of investment securities and sold $17,931,291,000 of investment securities, other than temporary cash investments. Purchases and sales include $8,090,443,000 and $6,823,566,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $2,469,747,000 and $1,252,748,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

During the year ended December 31, 2017, the fund realized $1,325,381,000 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, 2017, the fund had $2,110,000 of ordinary income available for distribution. At December 31, 2017, the fund had available capital losses totaling $1,439,318,000 to offset future net capital gains. Of this amount, $261,118,000 is subject to expiration on December 31, 2018. Capital losses of $1,178,200,000 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 $243,082,000 expired on December 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At December 31, 2017, the cost of investment securities for tax purposes was $15,611,902,000. Net unrealized appreciation of investment securities for tax purposes was $5,824,232,000, consisting of unrealized gains of $6,679,033,000 on securities that had risen in value since their purchase and $854,801,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $7,056,960,000 of investment securities and sold $6,247,493,000 of investment securities, other than temporary cash investments. Purchases and sales include $2,529,364,000 and $2,538,461,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $558,641,000 and $1,410,580,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

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.

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 event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at December 31, 2017, or at any time during the period then ended.

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, 2017, the fund had contributed to Vanguard capital in the amount of $1,629,000, representing 0.01% of the fund’s net assets and 0.65% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3

During the year ended December 31, 2017, the fund realized $1,112,805,000 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.

Small-Cap Value Index Fund

For tax purposes, at December 31, 2017, the fund had $11,652,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $77,600,000 to offset taxable capital gains realized during the year ended December 31, 2017. At December 31, 2017, the fund had available capital losses totaling $763,172,000 to offset future net capital gains. Of this amount, $388,774,000 is subject to expiration on December 31, 2018. Capital losses of $374,398,000 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 $487,808,000 expired on December 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in-capital.

At December 31, 2017, the cost of investment securities for tax purposes was $23,479,750,000. Net unrealized appreciation of investment securities for tax purposes was $6,343,807,000, consisting of unrealized gains of $7,625,133,000 on securities that had risen in value since their purchase and $1,281,326,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $9,965,325,000 of investment securities and sold $7,600,033,000 of investment securities, other than temporary cash investments. Purchases and sales include $3,572,378,000 and $2,370,226,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $2,396,737,000 and $961,562,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

Report of Independent Registered
Public Accounting Firm

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

Opinions on the Financial Statements

We have audited the accompanying statements of net assets—investments summary of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund (three of the funds constituting Vanguard Index Funds, hereafter collectively referred to as the “Funds”) as of December 31, 2017, the related statements of operations for the year ended December 31, 2017, the statements of changes in net assets for each of the two years in the period ended December 31, 2017, including the related notes, and the financial highlights for each of the five years in the period ended December 31, 2017 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of December 31, 2017, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended December 31, 2017 and each of the financial highlights for each of the five years in the period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of December 31, 2017 by correspondence with the custodians and brokers and by agreement to the underlying ownership records of the transfer agent; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

About Your Fund’s Expenses

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


Six Months Ended December 31, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	6/30/2017	12/31/2017	Period
Based on Hypothetical 5% Yearly Return

Admiral Shares	1,000.00	1,025.00	0.20
Institutional Shares	1,000.00	1,025.05	0.15
Institutional Plus Shares	1,000.00	1,025.10	0.10
Small-Cap Growth Index Fund
Investor Shares	$1,000.00	$1,024.25	$0.97
ETF Shares	1,000.00	1,024.85	0.36
Admiral Shares	1,000.00	1,024.85	0.36
Institutional Shares	1,000.00	1,024.90	0.31
Small-Cap Value Index Fund
Investor Shares	$1,000.00	$1,024.30	$0.92
ETF Shares	1,000.00	1,024.85	0.36
Admiral Shares	1,000.00	1,024.85	0.36
Institutional Shares	1,000.00	1,024.90	0.31

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, 0.16% for Investor Shares, 0.04% for ETF Shares, 0.04% for Admiral Shares, 0.03% for
Institutional Shares, and 0.02% for Institutional Plus Shares; for the Small-Cap Growth Index Fund, 0.19% for Investor Shares, 0.07% for
ETF Shares, 0.07% for Admiral Shares, and 0.06% for Institutional Shares; and for the Small-Cap Value Index Fund, 0.18% for Investor
Shares, 0.07% for ETF Shares, 0.07% for Admiral Shares, and 0.06% 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).

Chairman’s Perspective

Bill McNabb
Chairman

Dear Shareholder,

When you’re just starting out, there is nothing quite like getting votes of confidence from people you respect.

The short list

A milestone like this naturally brings about some reflection. With that in mind, here’s a tally—by no means exhaustive—of the accomplishments that we at Vanguard are proud of:

Global diversification. Through our thought leadership and investment options, such as our target-date funds, Vanguard has encouraged clients to obtain exposure to international markets.

Global diversification isn’t just about helping to control risk—it can also be a way of expanding your set of opportunities and harnessing the potential of all markets.

I’ve been glad to see more and more clients embracing global diversification. I believe this trend will continue as Vanguard’s way of investing takes hold in international markets.

We’ve done a great job attracting new talent, too. We made some notable additions to senior management in the last two years, and we’re continuously grooming our next generation of leaders.

Ready for what comes next

During the year ended December 31, 2017, the fund realized $2,570,553,000 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, 2017, the fund had $13,850,000 of ordinary income available for distribution. At December 31, 2017, the fund had available capital losses totaling $1,163,440,000 to offset future net capital gains. Of this amount, $24,584,000 is subject to expiration on December 31, 2018. Capital loss carryforwards of $49,578,000 expired on December 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital. Capital losses of $1,138,856,000 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, 2017, the cost of investment securities for tax purposes was $46,977,167,000. Net unrealized appreciation of investment securities for tax purposes was $17,197,014,000, consisting of unrealized gains of $20,180,906,000 on securities that had risen in value since their purchase and $2,983,892,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $13,797,239,000 of investment securities and sold $11,247,337,000 of investment securities, other than temporary cash investments. Purchases and sales include $5,479,430,000 and $5,132,920,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Mid-Cap Index Fund

During the year ended December 31, 2017, the fund realized $2,770,245,000 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, 2017, the fund had $9,821,000 of ordinary income available for distribution. At December 31, 2017, the fund had available capital losses totaling $3,437,989,000 to offset future net capital gains. Of this amount, $294,968,000 is subject to expiration on December 31, 2018. Capital losses of $3,143,021,000 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, 2017, the cost of investment securities for tax purposes was $67,207,433,000. Net unrealized appreciation of investment securities for tax purposes was $27,681,520,000, consisting of unrealized gains of $29,407,673,000 on securities that had risen in value since their purchase and $1,726,153,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $21,643,915,000 of investment securities and sold $17,259,800,000 of investment securities, other than temporary cash investments. Purchases and sales include $6,558,728,000 and $5,213,929,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $655,963,000 and $2,919,879,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

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.

Mid-Cap Growth Index Fund

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

The fund had no borrowings outstanding at December 31, 2017, or at any time during the period then ended.

Mid-Cap Growth Index Fund

During the year ended December 31, 2017, the fund realized $345,993,000 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, 2017, the fund had $202,000 of ordinary income available for distribution. At December 31, 2017, the fund had available capital losses totaling $613,501,000 to offset future net capital gains. Of this amount, $73,214,000 is subject to expiration on December 31, 2018. Capital losses of $540,287,000 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, 2017, the cost of investment securities for tax purposes was $8,821,475,000. Net unrealized appreciation of investment securities for tax purposes was $2,472,897,000, consisting of unrealized gains of $2,673,340,000 on securities that had risen in value since their purchase and $200,443,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $4,552,216,000 of investment securities and sold $3,043,236,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,414,779,000 and $762,834,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $402,205,000 and $768,494,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

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.

Mid-Cap Value Index Fund

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

The fund had no borrowings outstanding at December 31, 2017, or at any time during the period then ended.

Mid-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, 2017, the fund had contributed to Vanguard capital in the amount of $928,000, representing 0.01% of the fund’s net assets and 0.37% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2017, based on the inputs used to value them:

Mid-Cap Value Index Fund

During the year ended December 31, 2017, the fund realized $484,277,000 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, 2017, the fund had $2,737,000 of ordinary income available for distribution. At December 31, 2017, the fund had available capital losses totaling $634,867,000 to offset future net capital gains. Of this amount, $4,037,000 is subject to expiration on December 31, 2018. Capital losses of $630,830,000 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, 2017, the cost of investment securities for tax purposes was $13,730,445,000. Net unrealized appreciation of investment securities for tax purposes was $3,454,691,000, consisting of unrealized gains of $3,826,780,000 on securities that had risen in value since their purchase and $372,089,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $5,989,913,000 of investment securities and sold $3,914,903,000 of investment securities, other than temporary cash investments. Purchases and sales include $2,079,235,000 and $1,290,889,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $613,856,000 and $963,311,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

Report of Independent Registered
Public Accounting Firm

To the Board of Trustees of Vanguard Index Funds and 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

Opinions on the Financial Statements

We have audited the accompanying statement of net assets—investments summary of Vanguard Extended Market Index Fund and the statements of net assets of Vanguard Mid-Cap Index Fund, Vanguard Mid-Cap Growth Index Fund and Vanguard Mid-Cap Value Index Fund (four of the funds constituting Vanguard Index Funds, hereafter collectively referred to as the “Funds”) as of December 31, 2017, the related statements of operations for the year ended December 31, 2017, the statements of changes in net assets for each of the two years in the period ended December 31, 2017, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of December 31, 2017, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended December 31, 2017 and each of the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of December 31, 2017 by correspondence with the custodians and brokers and by agreement to the underlying ownership records of the transfer agent; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

Special 2017 tax information (unaudited) for Vanguard U.S. Stock Index Funds
(Mid-Capitalization Portfolios)

This information for the fiscal year ended December 31, 2017, is included pursuant to provisions of the Internal Revenue Code.

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


Fund	($000)
Extended Market Index Fund	520,195
Mid-Cap Index Fund	1,102,180
Mid-Cap Growth Index Fund	56,494
Mid-Cap Value Index Fund	286,357

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
Extended Market Index Fund	63.4%
Mid-Cap Index Fund	80.1
Mid-Cap Growth Index Fund	71.0
Mid-Cap Value Index Fund	82.1

Your Fund’s After-Tax Returns

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.

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, 0.21% for Investor Shares, 0.08% for ETF Shares, 0.08% for Admiral Shares, 0.06%
for Institutional Shares, 0.05% for Institutional Plus Shares, and 0.02% for Institutional Select Shares; for the Mid-Cap Index Fund, 0.16%
for Investor Shares, 0.04% for ETF Shares, 0.04% for Admiral Shares, 0.03% for Institutional Shares, and 0.02% for Institutional Plus
Shares; for the Mid-Cap Growth Index Fund, 0.19% for Investor Shares, 0.07% for ETF Shares, and 0.07% for Admiral Shares; and for the
Mid-Cap Value Index Fund, 0.19% for Investor Shares, 0.07% for ETF Shares, and 0.07% 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).

Chairman’s Perspective

Bill McNabb
Chairman

Dear Shareholder,

When you’re just starting out, there is nothing quite like getting votes of confidence from people you respect.

The short list

A milestone like this naturally brings about some reflection. With that in mind, here’s a tally—by no means exhaustive—of the accomplishments that we at Vanguard are proud of:

Global diversification. Through our thought leadership and investment options, such as our target-date funds, Vanguard has encouraged clients to obtain exposure to international markets.

Global diversification isn’t just about helping to control risk—it can also be a way of expanding your set of opportunities and harnessing the potential of all markets.

I’ve been glad to see more and more clients embracing global diversification. I believe this trend will continue as Vanguard’s way of investing takes hold in international markets.

We’ve done a great job attracting new talent, too. We made some notable additions to senior management in the last two years, and we’re continuously grooming our next generation of leaders.

Ready for what comes next

Proposal 2—Approve a manager-of-managers arrangement with third-party investment advisors.

Proposal 3—Approve a manager-of-managers arrangement with wholly owned subsidiaries of Vanguard.

Growth Index Fund	439,170,233	13,569,346	15,130,579	78,604,725	80.4%

Value Index Fund	587,325,882	17,020,893	12,051,716	107,835,982	81.1%

Shareholders of Vanguard Growth Index Fund and Vanguard Value Index Fund did not approve the following proposal:

The trustees recommended a vote against the proposal for the following reasons: (1) Vanguard is fully compliant with all applicable U.S. laws and regulations that prohibit the investment in any company owned or controlled by the government of Sudan; (2) the addition of further investment constraints is not in fund shareholders’ best interests if those constraints are unrelated to a fund’s stated investment objective, policies, and strategies; and (3) divestment is an ineffective means to implement social change, as it often puts the shares into the hands of another owner with no direct impact to the company’s capitalization.

Growth Index Fund

During the year ended December 31, 2017, the fund realized $2,805,087,000 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, 2017, the fund had $5,268,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $130,485,000 to offset taxable capital gains realized during the year ended December 31, 2017. At December 31, 2017, the fund had available capital losses totaling $1,138,498,000 that may be carried forward indefinitely to offset future net capital gains. Capital loss carryforwards of $300,177,000 expired on December 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At December 31, 2017, the cost of investment securities for tax purposes was $43,425,278,000. Net unrealized appreciation of investment securities for tax purposes was $29,847,101,000, consisting of unrealized gains of $30,401,014,000 on securities that had risen in value since their purchase and $533,913,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $14,679,629,000 of investment securities and sold $10,498,708,000 of investment securities, other than temporary cash investments. Purchases and sales include $6,677,020,000 and $5,154,222,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $1,063,300,000 and $2,193,661,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

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.

Value Index Fund

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

The fund had no borrowings outstanding at December 31, 2017, or at any time during the period then ended.

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, 2017, the fund had contributed to Vanguard capital in the amount of $3,524,000, representing 0.01% of the fund’s net assets and 1.41% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments). Any investments valued with significant unobservable inputs are
noted on the Statement of Net Assets.

The following table summarizes the market value of the fund’s investments as of December 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3

Value Index Fund

During the year ended December 31, 2017, the fund realized $1,789,646,000 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, 2017, the fund had $10,700,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $194,036,000 to offset taxable capital gains realized during the year ended December 31, 2017. At December 31, 2017, the fund had available capital losses totaling $558,094,000 that may be carried forward indefinitely to offset future net capital gains. Capital loss carryforwards of $333,377,000 expired on December 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At December 31, 2017, the cost of investment securities for tax purposes was $48,652,168,000. Net unrealized appreciation of investment securities for tax purposes was $16,379,764,000, consisting of unrealized gains of $17,615,648,000 on securities that had risen in value since their purchase and $1,235,884,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $15,700,572,000 of investment securities and sold $9,347,867,000 of investment securities, other than temporary cash investments. Purchases and sales include $8,671,185,000 and $4,399,380,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $1,987,844,000 and $1,497,383,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

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.

Large-Cap Index Fund

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

The fund had no borrowings outstanding at December 31, 2017, or at any time during the period then ended.

Large-Cap 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, 2017, the fund had contributed to Vanguard capital in the amount of $1,019,000, representing 0.01% of the fund’s net assets and 0.41% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	18,564,833	—	—
Temporary Cash Investments	18,178	4,093	—
Futures Contracts—Liabilities¹	(58)	—	—
Total	18,582,953	4,093	—
1 Represents variation margin on the last day of the reporting period.

Large-Cap Index Fund

During the year ended December 31, 2017, the fund realized $193,166,000 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, 2017, the fund had $2,578,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $25,118,000 to offset taxable capital gains realized during the year ended December 31, 2017. At December 31, 2017, the fund had available capital losses totaling $118,637,000 to offset future net capital gains. Of this amount, $24,177,000 is subject to expiration on December 31, 2018. Capital losses of $94,460,000 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, 2017, the cost of investment securities for tax purposes was $11,676,061,000. Net unrealized appreciation of investment securities for tax purposes was $6,911,043,000, consisting of unrealized gains of $7,138,365,000 on securities that had risen in value since their purchase and $227,322,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $2,637,502,000 of investment securities and sold $840,557,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,581,444,000 and $318,266,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended December 31, 2017, such purchases and sales were $75,450,000 and $93,360,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

Report of Independent Registered
Public Accounting Firm

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

Opinions on the Financial Statements

We have audited the accompanying statements of net assets of Vanguard Growth Index Fund, Vanguard Value Index Fund and Vanguard Large-Cap Index Fund (three of the funds constituting Vanguard Index Funds, hereafter collectively referred to as the “Funds”) as of December 31, 2017, the related statements of operations for the year ended December 31, 2017, the statements of changes in net assets for each of the two years in the period ended December 31, 2017, including the related notes, and the financial highlights for each of the five years in the period ended December 31, 2017 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of December 31, 2017, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended December 31, 2017 and each of the financial highlights for each of the five years in the period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of December 31, 2017 by correspondence with the custodians and brokers and by agreement to the underlying ownership records of the transfer agent; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

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, 0.16% for Investor Shares, 0.04% for ETF Shares, 0.04% for Admiral Shares, and 0.03% for
Institutional Shares; for the Value Index Fund, 0.16% for Investor Shares, 0.04% for ETF Shares, 0.04% for Admiral Shares, and 0.03% for
Institutional Shares; and for the Large-Cap Index Fund, 0.16% for Investor Shares, 0.04% for ETF Shares, 0.04% for Admiral Shares, and
0.04% 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).

Your Fund’s Performance at a Glance

• Vanguard Total Stock Market Index Fund returned about 21% for the 12 months ended December 31, 2017. The fund closely tracked its target index, the CRSP US Total Market Index, and exceeded the average return of its multicapitalization core fund peers.

• The fund offers investors exposure to every segment, size, and style of the U.S. equity market.

• For the 12 months, large-cap stocks outperformed their small- and mid-cap counterparts. Growth stocks outpaced value.

• Nine of the fund’s ten market sectors recorded positive returns, with technology, financials, and industrials contributing most to overall performance. Eight sectors had double-digit returns.

• Oil and gas and telecommunications were the only detractors.

• For the ten years ended December 31, 2017, the fund posted an average annual return of well over 8%, in line with its benchmark and about 2 percentage points higher than its peer average.

Chairman’s Perspective

Bill McNabb
Chairman

Dear Shareholder,

When you’re just starting out, there is nothing quite like getting votes of confidence from people you respect.

The short list

A milestone like this naturally brings about some reflection. With that in mind, here’s a tally—by no means exhaustive—of the accomplishments that we at Vanguard are proud of:

Global diversification. Through our thought leadership and investment options, such as our target-date funds, Vanguard has encouraged clients to obtain exposure to international markets.

Global diversification isn’t just about helping to control risk—it can also be a way of expanding your set of opportunities and harnessing the potential of all markets.

I’ve been glad to see more and more clients embracing global diversification. I believe this trend will continue as Vanguard’s way of investing takes hold in international markets.

We’ve done a great job attracting new talent, too. We made some notable additions to senior management in the last two years, and we’re continuously grooming our next generation of leaders.

Ready for what comes next

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 six classes of shares: Investor Shares, ETF Shares, Admiral Shares, Institutional Shares, Institutional Plus Shares, and Institutional Select Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares, Institutional Shares, Institutional Plus Shares, and Institutional Select Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Total Stock Market Index Fund

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 event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at December 31, 2017, or at any time during the period then ended.

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, 2017, the fund had contributed to Vanguard capital in the amount of $36,381,000, representing 0.01% of the fund’s net assets and 14.55% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including quoted prices for similar securities, interest
rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine
the fair value of investments). Any investments valued with significant unobservable inputs are
noted on the Statement of Net Assets.

The following table summarizes the market value of the fund’s investments as of December 31, 2017, based on the inputs used to value them:

During the year ended December 31, 2017, the fund realized $5,768,376,000 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, 2017, the fund had $110,357,000 of ordinary income available for distribution. The fund had available capital losses of $1,660,426,000 that maybe carried forward indefinitely to offset future net capital gains.

Total Stock Market Index Fund

At December 31, 2017, the cost of investment securities for tax purposes was $414,242,793,000. Net unrealized appreciation of investment securities for tax purposes was $251,916,458,000, consisting of unrealized gains of $264,454,492,000 on securities that had risen in value since their purchase and $12,538,034,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2017, the fund purchased $91,249,809,000 of investment securities and sold $26,635,458,000 of investment securities, other than temporary cash investments. Purchases and sales include $18,352,925,000 and $8,363,542,000, 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 Shareholders of Vanguard Total Stock Market Index Fund

Opinion on the Financial Statements

We have audited the accompanying statement of net assets—investments summary of Vanguard Total Stock Market Index Fund (one of the funds constituting Vanguard Index Funds, referred to hereafter as the “Fund”) as of December 31, 2017, the related statement of operations for the year ended December 31, 2017, the statement of changes in net assets for each of the two years in the period ended December 31, 2017, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of December 31, 2017, 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 ended December 31, 2017 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Your Fund’s After-Tax Returns

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

Average Annual Total Returns: Total Stock Market Index Fund Investor Shares
Periods Ended December 31, 2017


	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	21.05%	15.42%	8.60%
Returns After Taxes on Distributions	20.53	14.91	8.19
Returns After Taxes on Distributions and Sale of Fund Shares	12.25	12.33	6.94

About Your Fund’s Expenses

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


Six Months Ended December 31, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Total Stock Market Index Fund	6/30/2017	12/31/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,111.17	$0.75
ETF Shares	1,000.00	1,111.66	0.21
Admiral Shares	1,000.00	1,111.71	0.21
Institutional Shares	1,000.00	1,111.70	0.21
Institutional Plus Shares	1,000.00	1,111.66	0.11
Institutional Select Shares	1,000.00	1,111.81	0.05
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,024.50	$0.71
ETF Shares	1,000.00	1,025.00	0.20
Admiral Shares	1,000.00	1,025.00	0.20
Institutional Shares	1,000.00	1,025.00	0.20
Institutional Plus Shares	1,000.00	1,025.00	0.10
Institutional Select Shares	1,000.00	1,024.70	0.05

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for
that period are 0.14% for Investor Shares, 0.04% for ETF Shares, 0.04% for Admiral Shares, 0.035% for Institutional Shares, 0.02% for
Institutional Plus Shares, and 0.01% for Institutional Select Shares. The dollar amounts shown as “Expenses Paid” are equal to the
annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent
six-month period, then divided by the number of days in the most recent 12-month period (184/365).

In making a determination, the Audit Committee considers whether the services are consistent with maintaining the principal accountant’s independence.

In the event of a contingency situation in which the principal accountant is needed to provide services in between scheduled Audit Committee meetings, the Chairman of the Audit Committee would be called on to consider and, if appropriate, pre-approve audit or permitted non-audit services in an amount sufficient to complete services through the next Audit Committee meeting, and to determine if such services would be consistent with maintaining the accountant’s independence. At the next scheduled Audit Committee meeting, services and fees would be presented to the Audit Committee for formal consideration, and, if appropriate, approval by the entire Audit Committee. The Audit Committee would again consider whether such services and fees are consistent with maintaining the principal accountant’s independence.

The Registrant’s Audit Committee is informed at least annually of all audit and non-audit services provided by the principal accountant to the Vanguard complex, whether such services are provided to: the Registrant, other registered investment companies in the Vanguard complex, The Vanguard Group, Inc., or other entities controlled by The Vanguard Group, Inc. that provide ongoing services to the Registrant.

Report of Independent Registered Public Accounting Firm

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

Opinions on the Financial Statements

We have audited the accompanying statements of net assets—investments summary of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund (three of the funds constituting Vanguard Index Funds, hereafter collectively referred to as the "Funds") as of December 31, 2017, the related statements of operations for the year ended December 31, 2017, the statements of changes in net assets for each of the two years in the period ended December 31, 2017, including the related notes, and the financial highlights for each of the five years in the period ended December 31, 2017 (included in Item 1 of this Form N-CSR) and the schedules of investments (included in Item 6 of this Form N-CSR) as of December 31, 2017 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of December 31, 2017, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended December 31, 2017 and each of the financial highlights for each of the five years in the period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of December 31, 2017 by correspondence with the custodians and brokers and by agreement to the underlying ownership records of the transfer agent; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.
