About the cover: Our cover photograph shows rigging on the HMSSurprise, a replica of an 18th-century Royal Navy frigate. It was featured in the 2003 movie Master and Commander: The Far Side of the World, which was based on Patrick O’Brian’s sea novels, set amid the Napoleonic Wars. Vanguard was named for another ship of that era, the HMSVanguard, which was the flagship of British Admiral Horatio Nelson at the Battle of the Nile.

Chairman’s Letter

Dear Shareholder,

Vanguard 500 Index Fund returned about 16% for the 12 months ended December 31, 2012, posting its best fiscal-year result since 2009. The fund closely tracked its target, the Standard & Poor’s 500 Index, and outperformed the average return of peer funds.

A rebound in financials—the worst-performing sector in 2011—helped drive the index’s advance. All ten industry sectors had positive returns for the year; utility stocks had the smallest gain.

If you own the fund in a taxable account, you may wish to review the information on after-tax returns presented later in this report.

With help from central banks, stocks posted strong results
Stocks around the world recorded double-digit gains for the 12 months ended December 31, with international stocks faring even better than their U.S. counterparts.

European stocks shook off investors’ concerns to deliver some of the best results, rising about 19%. The rally came as European central bankers moved to address worries about the finances of governments and banks. Still, Vanguard economists expect Europe to remain a trouble spot, with occasional spikes in market volatility, as fiscal tightening persists in the face of weak economic growth.

In the United States, the Federal Reserve continued buying bonds and mortgage-backed securities to try to stimulate growth. The Fed’s actions seemed to buoy both stock and bond returns.

Attention to the nation’s considerable budget challenges intensified as 2012 drew to a close. The focus on the “fiscal cliff” led to nervousness in the markets before policymakers reached a limited tax-rate agreement on the cusp of the new year. The compromise legislation, which President Barack Obama signed into law on January 2, addressed some immediate concerns, but a credible long-term deficit-reduction strategy had yet to be crafted to resolve the nation’s fiscal imbalance and open the way for growth.

Bond returns were solid, but challenges lie ahead
The broad U.S. taxable bond market returned about 4% for the 12 months. Municipal bonds performed especially well, returning more than 6%.

As bond prices rose, the yield of the 10-year U.S. Treasury note slipped to a record low in July, closing below 1.5%. (Bond yields and prices move in opposite directions.) By the end of the period, the yield had climbed, but it remained exceptionally low by historical standards.

Although bonds can provide critical diversification benefits to a portfolio, their return prospects look much less promising

than the results achieved in recent years As yields have tumbled, the opportunity for future bond price appreciation has greatly diminished. (You can read more about our expectations for bond and stock returns in Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.)

As it has since late 2008, the Fed held its target for short-term interest rates between 0% and 0.25%, which kept a tight lid on returns from money market funds and savings accounts.

Financial, tech stocks rallied; utility, energy stocks lagged
As I mentioned earlier, financial stocks were among the best performers for the year as banks, brokerages, and finance companies put some more distance between their balance sheets and the financial crisis. Bank stocks seemed to get a further lift as the U.S. housing recovery gathered strength—a development that benefited shares of home improvement retailers and home builders as well.

The benchmark’s largest sector, information technology, also boosted returns significantly as the “ripple effect” of the growing popularity of smartphones and tablet computers spread from computer hardware manufacturers to software and internet companies. IT services and communication equipment firms also benefited from consumer and corporate demand.


Expense Ratios
Your Fund Compared With Its Peer Group

	Investor	Admiral	Signal	ETF	Peer Group
	Shares	Shares	Shares	Shares	Average
500 Index Fund	0.17%	0.05%	0.05%	0.05%	1.19%

The fund expense ratios shown are from the prospectus dated April 26, 2012, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2012, the fund’s expense ratios were 0.17% for Investor Shares, 0.05% for Admiral Shares, 0.05% for Signal Shares, and 0.05% for ETF Shares. The peer-group expense ratio is derived from data provided by Lipper Inc. and captures information through year-end 2011.

Peer group: Large-Cap Core Funds.

Weak spots included energy and utility stocks. Economic sluggishness has restrained power and energy demand, while the abundance of natural gas has put pressure on oil and gas prices.

Your fund has delivered solid long-term results
For the ten-year period ended December 31, Investor Shares of the 500 Index Fund produced an average annual return of just under 7%. By historical standards, the results don’t appear especially impressive—until, that is, you consider the challenges of the past decade. Over the ten years, investors endured some traumatic events, including the aftermath of the bursting of the technology bubble in the early 2000s and the more recent financial crisis and global recession. The fund emerged from that turbulence with a ten-year average return that was more than a percentage point better than the average return of peer funds.

Through the market’s ups and downs, the fund met its goal of closely tracking the S&P 500 Index. This success reflects the skill of the advisor, Vanguard Equity Investment Group. The group relies on its proven portfolio management strategies in seeking to produce benchmark-tracking returns regardless of external market conditions. At the same time, the fund’s low costs help you keep your share of the market’s returns.

The figures shown represent past performance, which is not a guarantee of future results. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our website at vanguard.com/performance.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost.

Gus Sauter united traditional values with pioneering investment acumen
When I was interviewing for a job at Vanguard in the mid-1980s, Jack Brennan, who would go on to become our chairman and chief executive officer and is now chairman emeritus, described Vanguard as “a company with the intellectual rigor of Wall Street but with Midwestern values.”

I’m reminded of that when I think about Gus Sauter’s 25-year career at Vanguard. Gus retired as our chief investment officer at the end of December, having set the highest of standards for both intellectual achievement and devotion to doing the right thing for clients, colleagues, and community.

Gus played a pivotal role in transforming indexing from a novelty to an investing mainstay, a change that has benefited all investors. In addition, he developed our active quantitative equity strategies, oversaw the growth of our industry-leading expertise in fixed income, and ultimately helped Vanguard to become a global investment manager responsible for $2 trillion in client assets.

As for the Midwestern values, Gus—a native of Ohio, incidentally—served our clients with a dedication to thrift, candor, and common sense that has helped make Vanguard what it is. His colleagues knew that in any situation they could count on him to keep a level-headed, long-term outlook. Just two weeks after he started at Vanguard, he helped guide us through the stock market crash of 1987. Some 20 years later, he helped us navigate the financial crisis of 2008–2009.

An important aspect of Gus’s legacy is the team of world-class investment professionals that he cultivated at Vanguard. That team is now led by Tim Buckley, who oversaw our services for individual investors before becoming chief investment officer. I am confident that Tim will not only carry on Gus’s legacy, but also—as Gus himself put it—take Vanguard investment management to the next level.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

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

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

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

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal 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).

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

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, 2009–2012), 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.

500 Index Fund

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

6. 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. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $16,101,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 6.44% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Various inputs may be used to determine the value of the fund’s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

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

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	118,284,029	—	—
Temporary Cash Investments	220,010	17,146	—
Futures Contracts—Assets¹	6,155	—	—
Total	118,510,194	17,146	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2012, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
S&P 500 Index	March 2013	584	207,335	739
E-mini S&P 500 Index	March 2013	490	34,792	(110)

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

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

During the year ended December 31, 2012, the fund realized $1,827,661,000 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, 2012, the fund had $18,950,000 of ordinary income available for distribution. At December 31, 2012, the fund had available capital losses totaling $3,151,728,000 to offset future net capital gains. Of this amount $2,057,911,000 is subject to expiration dates; $293,941,000 may be used to offset future net capital gains through December 31, 2014, and $1,763,970,000 through December 31, 2016. Capital losses of $1,093,817,000 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, 2012, the cost of investment securities for tax purposes was $79,320,502,000. Net unrealized appreciation of investment securities for tax purposes was $39,200,683,000, consisting of unrealized gains of $47,354,816,000 on securities that had risen in value since their purchase and $8,154,133,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2012, the fund purchased $9,967,290,000 of investment securities and sold $6,867,873,000 of investment securities, other than temporary cash investments. Purchases and sales include $4,325,614,000 and $2,948,499,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Report of Independent Registered
Public Accounting Firm

To the Trustees of Vanguard Index Funds and the Shareholders of Vanguard 500 Index Fund: In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard 500 Index Fund (constituting a separate portfolio of Vanguard Index Funds, hereafter referred to as the “Fund”) at December 31, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2012 by correspondence with the custodian and broker and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Special 2012 tax information (unaudited) for Vanguard 500 Index Fund

This information for the fiscal year ended December 31, 2012, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $2,506,710,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 98.3% of investment income (dividend income plus short-term gains, if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

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

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

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

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

About Your Fund’s Expenses

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

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

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

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

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

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

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

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

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

Signal Shares	1,000.00	1,024.95	0.26
ETF Shares	1,000.00	1,024.95	0.26

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.17% for Investor Shares, 0.05% for Admiral Shares, 0.05% for Signal Shares, and 0.05% for ETF 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.

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 180 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.

Chairman’s Letter

Dear Shareholder,

After recording negative returns for 2011, Vanguard’s three small-capitalization index funds rebounded in 2012. A strengthening U.S. housing market contributed to this advance.

For the 12 months ended December 31, 2012, Vanguard Small-Cap Value Index Fund returned 18.56%, surpassing the 17.52% return of Vanguard Small-Cap Growth Index Fund. Vanguard Small-Cap Index Fund, which includes both growth and value stocks, returned 18.04%. (All returns are for the funds’ Investor Shares.)

Each of the small-cap index funds closely tracked the performance of its respective index, and also surpassed the average return of its respective peer group.

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

With help from central banks, stocks posted strong results
Stocks around the world recorded double-digit gains for the 12 months ended December 31, with international stocks faring even better than their U.S. counterparts.

finances of governments and banks. Still, Vanguard economists expect Europe to remain a trouble spot, with occasional spikes in market volatility, as fiscal tightening persists in the face of weak economic growth.

In the United States, the Federal Reserve continued buying bonds and mortgage-backed securities to try to stimulate growth. The Fed’s actions seemed to buoy both stock and bond returns.

Attention to the nation’s considerable budget challenges intensified as 2012 drew to a close. The focus on the “fiscal cliff” led to nervousness in the markets before policymakers reached a limited tax-rate agreement on the cusp of the new year. The compromise legislation, which President Barack Obama signed into law on January 2, addressed some immediate concerns, but a credible long-term deficit-reduction strategy has yet to be crafted to resolve the nation’s fiscal imbalance and open the way for growth.

Bond returns were solid, but challenges lie ahead
The broad U.S. taxable bond market returned about 4% for the 12 months. Municipal bonds performed especially well, returning more than 6%.

As bond prices rose, the yield of the 10-year U.S. Treasury note slipped to a record low in July, closing below 1.5%. (Bond yields and prices move in opposite

directions.) By the end of the period, the yield had climbed, but it remained exceptionally low by historical standards.

Although bonds can provide critical diversification benefits to a portfolio, their return prospects look much less promising than in recent years. As yields have tumbled, the opportunity for future bond price appreciation has greatly diminished. (You can read more about our expectations for bond and stock returns in Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.)

As it has since late 2008, the Fed held its target for short-term interest rates between 0% and 0.25%, which kept a tight lid on returns from money market funds and savings accounts.

The financial sector helped small-cap value stocks excel
Although it was a good year for stocks of all sizes, small-caps outperformed their larger counterparts. The Small-Cap Value Index Fund, which has an outsized allocation to financials, performed best. The fund gained about 40% of its return for the year from the sector. Financial stocks surged as the U.S. housing recovery gained traction.

The fund expense ratios shown are from the prospectus dated April 26, 2012, as supplemented, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2012, the funds’ expense ratios were: for the Small-Cap Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, 0.06% for Institutional Plus Shares, and 0.10% for ETF Shares; for the Small-Cap Growth Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; and for the Small-Cap Value Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares. The peer-group expense ratios are derived from data provided by Lipper Inc. and capture information through year-end 2011.

Peer groups: For the Small-Cap Index Fund, Small-Cap Core Funds; for the Small-Cap Growth Index Fund, Small-Cap Growth Funds; for the Small-Cap Value Index Fund, Small-Cap Value Funds.

Real estate investment trusts (REITs) performed particularly well; property owners increased rents as the market improved, which translated to additional revenue and profit. In addition, investors searching for income were drawn to the relatively high yields of REITs.

Industrials also posted strong contributions to the Small-Cap Value Index Fund. With construction activity picking up, industrial machinery, construction equipment, and specialized vehicle manufacturers all turned in strong returns.

The Small-Cap Index Fund also benefited from the financial and industrial sectors, but to a lesser extent, since the two sectors combined represented a less substantial proportion of its portfolio.

The performance of the Small-Cap Growth Index Fund was driven mainly by health care and information technology. Health care stocks, including biotech firms, health care equipment suppliers, and service providers, accounted for more than 20% of the fund’s total return. Information technology companies, including software application and IT service providers, also

stood out. Because the fund’s target benchmark only focuses on growth-oriented stocks, the fund held less of some of the best-performing sectors, including financials, in its portfolio.

For all three funds, the energy sector detracted the most from returns. Energy stocks struggled partly because of weak global demand and lower commodity prices.

The funds have produced a solid long-term record
For the decade ended December 31, Vanguard’s three small-cap index funds recorded average annual returns ranging from 11.02% for the Small-Cap Growth Index Fund to 9.61% for the Small-Cap Value Index Fund. Each fund’s average annual return for the ten-year period has exceeded that of its peer group.

In addition, each of the funds has tracked its index closely, even though the benchmarks’ returns reflect no operating or transaction costs. The funds’ success in this regard is a tribute to the skill of their investment advisor, Vanguard Equity Investment Group, whose sophisticated portfolio construction and management techniques reflect more than 30 years of indexing experience. The advisor has been aided in this task by each fund’s low expenses.

Funds will seek to track new benchmark indexes
In early October, we announced that the three funds discussed in this report would adopt new target benchmarks as part of a broader transition affecting 22 of our index funds. This transition, which we plan to complete by the middle of the year, is expected to produce significant long-term savings for Vanguard clients. As of January 31, we had already completed the transition for Vanguard Small-Cap Index Fund.

The new benchmarks for the three funds are supplied by the University of Chicago’s Center for Research in Security Prices (CRSP). CRSP is one of 11 research centers at the University of Chicago Booth School of Business. In 1960, the research organization pioneered the development of U.S. stock market data that are widely used in academic and investment research today.

helped Vanguard to become a global investment manager responsible for $2 trillion in client assets.

An important aspect of Gus’s legacy is the team of world-class investment professionals that he cultivated at Vanguard. That team is now led by

Tim Buckley, who oversaw our services for individual investors before becoming chief investment officer. I am confident that Tim will not only carry on Gus’s legacy, but also—as Gus himself put it—take Vanguard investment management to the next level.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

A note on expense ratios

The Expense Ratios table in each report’s Chairman’s Letter displays fund expense

ratios from the most recent prospectus. These figures include the funds’ actual

operating expenses. For some funds, the figures also include “acquired fund fees

and expenses,” which result from the funds’ holdings in business development

companies (BDCs).

Although the Securities and Exchange Commission requires that BDC costs be

included in a fund’s expense ratio, these fees are not incurred by the fund. They

have no impact on a fund’s total return or on its tracking error relative to an index.

A footnote to the Expense Ratios table reports an annualized calculation of the fund’s

actual expenses for the period, a more relevant tally of the operating costs incurred

by shareholders.

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

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

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

Small-Cap Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $3,691,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.48% of Vanguard’s capitalization. The fund’s trustees and officers are also directors officers of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	27,537,446	—	283
Temporary Cash Investments	500,527	12,797	—
Futures Contracts—Assets¹	4,496	—	—
Futures Contracts—Liabilities¹	(31)	—	—
Total	28,042,438	12,797	283
1 Represents variation margin on the last day of the reporting period.

Small-Cap Index Fund

D. At December 31, 2012, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	March 2013	2,678	226,719	487

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

Certain of the fund’s investments are in securities considered to be “passive foreign investment companies,” for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2012, the fund realized gains on the sale of passive foreign investment companies of $151,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to overdistributed net investment income. Passive foreign investment companies held at December 31, 2012, had unrealized appreciation of $1,092,000.

During the year ended December 31, 2012, the fund realized $952,215,000 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, 2012, the fund had $4,836,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $279,085,000 to offset taxable capital gains realized during the year ended December 31, 2012. At December 31, 2012, the fund had available capital losses totaling $1,031,716,000 to offset future net capital gains. Of this amount, $946,157,000 is subject to expiration dates; $342,008,000 may be used to offset future net capital gains through December 31, 2017, and $604,149,000 through December 31, 2018. Capital losses of $85,559,000 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, 2012, the cost of investment securities for tax purposes was $25,694,638,000. Net unrealized appreciation of investment securities for tax purposes was $2,356,415,000, consisting of unrealized gains of $5,240,176,000 on securities that had risen in value since their purchase and $2,883,761,000 in unrealized losses on securities that had fallen in value since their purchase.

Small-Cap Growth Index Fund

Notes to Financial Statements

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

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

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

Small-Cap Growth Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $1,293,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.52% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	9,677,497	—	126
Temporary Cash Investments	170,227	2,000	—
Futures Contracts—Assets¹	515	—	—
Total	9,848,239	2,000	126
1 Represents variation margin on the last day of the reporting period.

Small-Cap Growth Index Fund

D. At December 31, 2012, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	March 2013	235	19,895	129

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

Certain of the fund’s investments are in securities considered to be “passive foreign investment companies,” for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2012, the fund realized gains on the sale of passive foreign investment companies of $1,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to overdistributed net investment income. Passive foreign investment companies held at December 31, 2012, had unrealized appreciation of $30,000 of which all has been distributed and is reflected in the balance of overdistributed net investment income.

During the year ended December 31, 2012, the fund realized $466,495,000 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, 2012, the fund had $861,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $27,529,000 to offset taxable capital gains realized during the year ended December 31, 2012. At December 31, 2012, the fund had available capital losses totaling $875,446,000 to offset future net capital gains. Of this amount, $800,828,000 is subject to expiration dates; $539,710,000 may be used to offset future net capital gains through December 31, 2017 and $261,118,000 through December 31, 2018. Capital losses of $74,618,000 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, 2012, the cost of investment securities for tax purposes was $8,819,887,000. Net unrealized appreciation of investment securities for tax purposes was $1,029,963,000, consisting of unrealized gains of $1,715,322,000 on securities that had risen in value since their purchase and $685,359,000 in unrealized losses on securities that had fallen in value since their purchase.

Small-Cap Growth Index Fund

F. During the year ended December 31, 2012, the fund purchased $5,106,028,000 of investment securities and sold $4,596,475,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,354,901,000 and $1,285,562,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

1 Inception was September 27, 2011, for Admiral Shares.

H. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced an upcoming change in the fund’s benchmark index from the MSCI US Small Cap Growth Index to the CRSP US Small Cap Growth Index. The fund’s investment objective is not changing. The transition to the new benchmark is expected to be completed over several months, and will require some turnover of holdings with resulting transaction costs. Vanguard will seek to minimize trading impact through efficient portfolio trading.

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

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

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

Small-Cap Value Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $1,036,000 to Vanguard (included in Other Assets), 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 officers of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	7,802,533	—	59
Temporary Cash Investments	44,079	2,999	—
Futures Contracts—Assets¹	714	—	—
Total	7,847,326	2,999	59
1 Represents variation margin on the last day of the reporting period.

Small-Cap Value Index Fund

D. At December 31, 2012, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	March 2013	326	27,599	440

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

Certain of the fund’s investments are in securities considered to be “passive foreign investment companies,” for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2012, the fund realized gains on the sale of passive foreign investment companies of $77,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to overdistributed net investment income. Passive foreign investment companies held at December 31, 2012, had unrealized appreciation of $632,000.

During the year ended December 31, 2012, the fund realized $307,360,000 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, 2012, the fund had $1,963,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $33,444,000 to offset taxable capital gains realized during the year ended December 31, 2012. At December 31, 2012, the fund had available capital losses totaling $1,196,884,000 to offset future net capital gains. Of this amount, $1,144,768,000 is subject to expiration dates; $755,994,000 may be used to offset future net capital gains through December 31, 2017, and $388,774,000 through December 31, 2018. Capital losses of $52,116,000 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, 2012, the cost of investment securities for tax purposes was $7,399,702,000. Net unrealized appreciation of investment securities for tax purposes was $449,968,000, consisting of unrealized gains of $1,057,550,000 on securities that had risen in value since their purchase and $607,582,000 in unrealized losses on securities that had fallen in value since their purchase.

Small-Cap Value Index Fund

F. During the year ended December 31, 2012, the fund purchased $3,087,912,000 of investment securities and sold $2,659,130,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,155,481,000 and $903,922,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

1 Inception was September 27, 2011, for Admiral Shares.

H. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced an upcoming change in the fund’s benchmark index from the MSCI US Small Cap Value Index to the CRSP US Small Cap Value Index. The fund’s investment objective is not changing. The transition to the new benchmark is expected to be completed over several months, and will require some turnover of holdings with resulting transaction costs. Vanguard will seek to minimize trading impact through efficient portfolio trading.

Report of Independent Registered
Public Accounting Firm

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

In our opinion, the accompanying statements of net assets—investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2012, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2012 by correspondence with the custodian and broker and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

About Your Fund’s Expenses

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.

• 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.

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, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, 0.06% for Institutional Plus Shares, and 0.10% for ETF Shares; for the Small-Cap Growth Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; and for the Small-Cap Value Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.08% for Institutional Shares, and 0.10% for ETF 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.

Chairman’s Letter

Dear Shareholder,

Vanguard’s four mid-capitalization stock index funds produced strong returns for 2012, as U.S. stocks bounced back from a lackluster 2011.

For the fiscal year ended December 31, Vanguard Extended Market Index Fund returned 18.31%. Vanguard Mid-Cap Index Fund, Vanguard Mid-Cap Growth Index Fund, and Vanguard Mid-Cap Value Index Fund each returned nearly 16%. (All returns are for the funds’ Investor Shares.)

All four funds closely tracked their target indexes for the year. All but the Value Fund outperformed the average returns of their peers.

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

European stocks shook off investors’ concerns to deliver some of the best results, rising about 19% compared with about 16% for U.S. stocks. The rally came as European central bankers moved to address worries about the finances of governments and banks. Still, Vanguard economists expect Europe to remain a

trouble spot, with occasional spikes in market volatility, as fiscal tightening persists in the face of weak economic growth.

In the United States, the Federal Reserve continued buying bonds and mortgage-backed securities to try to stimulate growth. The Fed’s actions seemed to buoy both stock and bond returns.

Bond returns were solid, but challenges lie ahead
The broad U.S. taxable bond market returned about 4% for the 12 months. Municipal bonds performed especially well, returning more than 6%.

Although bonds can provide critical diversification benefits to a portfolio, their prospects look much less promising than they had in recent years. As yields have tumbled, the opportunity for future bond price appreciation has greatly diminished. (You can read more about our expectations for bond and stock returns in Vanguard’s Economic and Investment Outlook, available at vanguard.com/research.)

As it has since late 2008, the Fed held its target for short-term interest rates between 0% and 0.25%, which kept a tight lid on returns from money market funds and savings accounts.

Financial sector’s turnaround boosted mid-cap funds’ results
The broad U.S. stock market began 2012 with its best first-quarter performance in more than a decade. With the U.S. economy showing promising growth and the Eurozone debt crisis seemingly under control, mid-cap stocks of all styles rose.

For the rest of the year, it was far from smooth sailing. Mid-cap stocks gave back most of their early gains by June before climbing relatively steadily through December, producing much stronger results than a year earlier, when returns were largely negative.

The Extended Market Index Fund, whose portfolio includes small-cap companies, posted the best 2012 return of the four funds in this report. Financial firms, its largest sector, enjoyed a remarkable turnaround in performance from 2011 and advanced 20%, providing the largest contribution to the fund’s returns. Banks, other diversified financial services providers, and companies that manage real estate also gained. And

consumer discretionary, industrial, and health care stocks delivered impressive results as well.

Year-end total returns for Investor Shares of the three other mid-cap funds varied by only about one-tenth of a percentage point, from 15.80% for the Mid-Cap Index Fund to 15.81% for the Growth Fund to 15.91% for the Value Fund. Sector performance was comparable to that

of the Extended Market Fund; financials, consumer discretionary, industrials, and health care did best.

The only weak sector across all four funds was energy (returns ranged from 1% to –3%), as falling U.S. crude oil prices squeezed industry profits.

The funds have produced a solid long-term record
For the decade ended December 31, 2012, the Extended Market Index Fund, helped by its inclusion of smaller-company stocks, returned an average of 10.58% a year for Investor Shares, with the Mid-Cap Index Fund not far behind at 9.90%. The Mid-Cap Growth and Value Index Funds—subsets of the Mid-Cap Index Fund—opened for business in August 2006; their average annual returns are more modest, as the 2008–2009 financial crisis diminished results for all stock funds.

Each of the four mid-cap funds has tracked its index closely, even though the benchmarks’ returns reflect no operating or transaction costs. Each fund’s average annual return has also surpassed that of its peer group.

The funds’ success in closely following their benchmarks’ performance is a tribute to their advisor, Vanguard Equity Investment Group, whose sophisticated portfolio construction and management techniques reflect more than 30 years of indexing experience. The advisor has been aided in this task, of course, by the funds’ low expenses.

Funds will seek to track new benchmark indexes
In early October, we announced that three of the four funds in this report would adopt new target benchmarks as part of a broader transition affecting 22 of our index funds. This transition, which we plan to complete by the middle of this year, is expected to produce significant long-term savings for Vanguard clients. As of January 31, we had already completed the transition for Vanguard Mid-Cap Index Fund.

The new benchmarks for the Mid-Cap Index, Mid-Cap Growth Index, and Mid-Cap Value Index Funds are supplied by the University of Chicago’s Center for Research in Security Prices (CRSP). CRSP is one of 11 research centers at the University of Chicago Booth School of Business. In 1960, the research organization pioneered the development of U.S. stock market data that are widely used in academic and investment research today.

Gus Sauter united traditional values with pioneering investment acumen
When I was interviewing for a job at Vanguard in the mid-1980s, Jack Brennan, who would go on to become our chairman and CEO and is now chairman emeritus, described Vanguard as “a company with the intellectual rigor of Wall Street but with Midwestern values.”

achievement and devotion to doing the right thing for clients, colleagues, and community.

As for the Midwestern values, Gus—a native of Ohio, incidentally—served our clients with a dedication to thrift, candor, and common sense that has helped make Vanguard what it is. His colleagues knew that in any situation they could count on Gus to keep a level-headed, long-term outlook. Just two weeks after he started at Vanguard, Gus helped guide us through the stock market crash of 1987. Some 20 years later, he helped us navigate the financial crisis of 2008–2009.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

A note on expense ratios

The Expense Ratios table in each report’s Chairman’s Letter displays fund expense

ratios from the most recent prospectus. These figures include the funds’ actual

operating expenses. For some funds, the figures also include “acquired fund fees

and expenses,” which result from the funds’ holdings in business development

companies (BDCs).

Although the Securities and Exchange Commission requires that BDC costs be

included in a fund’s expense ratio, these fees are not incurred by the fund. They

have no impact on a fund’s total return or on its tracking error relative to an index.

A footnote to the Expense Ratios table reports an annualized calculation of the

fund’s actual expenses for the period, a more relevant tally of the operating costs

incurred by shareholders.

Extended Market Index Fund

Notes to Financial Statements

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

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

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

Extended Market Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $3,155,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.26% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	23,434,972	—	435
Temporary Cash Investments	270,684	4,749	—
Futures Contracts—Assets¹	3,112	—	—
Futures Contracts—Liabilities¹	(548)	—	—
Total	23,708,220	4,749	435
1 Represents variation margin on the last day of the reporting period.

Extended Market Index Fund

D. At December 31, 2012, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-Mini S&P MidCap 400 Index	March 2013	542	55,181	(288)
E-mini Russell 2000 Index	March 2013	348	29,462	251

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

Certain of the fund’s investments are in securities considered to be “passive foreign investment companies,” for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. During the year ended December 31, 2012, the fund realized gains on the sale of passive foreign investment companies of $2,000, which have been included in current and prior periods’ taxable income; accordingly, such gains have been reclassified from accumulated net realized losses to overdistributed net investment income. Passive foreign investment companies held at December 31, 2012, had unrealized appreciation of $1,422,000.

During the year ended December 31, 2012, the fund realized $534,863,000 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, 2012, the fund had $6,626,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $574,494,000 to offset taxable capital gains realized during the year ended December 31, 2012. At December 31, 2012, the fund had available capital losses totaling $159,484,000 to offset future net capital gains. Of this amount, $74,162,000 is subject to expiration dates; $49,578,000 may be used to offset future net capital gains through December 31, 2017, and $24,584,000 through December 31, 2018. Capital losses of $85,322,000 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, 2012, the cost of investment securities for tax purposes was $20,914,906,000. Net unrealized appreciation of investment securities for tax purposes was $2,795,934,000, consisting of unrealized gains of $4,912,572,000 on securities that had risen in value since their purchase and $2,116,638,000 in unrealized losses on securities that had fallen in value since their purchase.

Extended Market Index Fund

F. During the year ended December 31, 2012, the fund purchased $6,248,207,000 of investment securities and sold $3,685,164,000 of investment securities, other than temporary cash investments. Purchases and sales include $2,728,768,000 and $1,182,927,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

Mid-Cap Index Fund

Notes to Financial Statements

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

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

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

Mid-Cap Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $4,292,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.72% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	31,976,589	—	—
Temporary Cash Investments	226,949	2,000	—
Futures Contracts—Assets¹	820	—	—
Total	32,204,358	2,000	—
1 Represents variation margin on the last day of the reporting period.

Mid-Cap Index Fund

D. At December 31, 2012, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P MidCap 400 Index	March 2013	355	36,143	(188)

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

During the year ended December 31, 2012, the fund realized $1,026,095,000 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, 2012, the fund had $5,455,000 of ordinary income available for distribution. At December 31, 2012, the fund had available capital losses totaling $2,593,882,000 to offset future net capital gains. Of this amount, $2,258,323,000 is subject to expiration dates; $1,696,225,000 may be used to offset future net capital gains through December 31, 2017, and $562,098,000 through December 31, 2018. Capital losses of $335,559,000 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, 2012, the cost of investment securities for tax purposes was $27,691,887,000. Net unrealized appreciation of investment securities for tax purposes was $4,513,651,000, consisting of unrealized gains of $6,484,335,000 on securities that had risen in value since their purchase and $1,970,684,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2012, the fund purchased $9,660,427,000 of investment securities and sold $7,401,956,000 of investment securities, other than temporary cash investments. Purchases and sales include $2,632,029,000 and $2,408,337,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Management has analyzed the fund’s tax positions taken for all open federal income tax years (December 31, 2009–2012), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

4. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

5. 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. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $348,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.14% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Mid-Cap Growth Index Fund

At December 31, 2012, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

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, 2012, the fund realized $167,898,000 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, 2012, the fund had $329,000 of ordinary income available for distribution. At December 31, 2012, the fund had available capital losses totaling $402,254,000 to offset future net capital gains. Of this amount, $286,740,000 is subject to expiration dates; $203,722,000 may be used to offset future net capital gains through December 31, 2017, and $83,018,000 through December 31, 2018. Capital losses of $115,514,000 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, 2012, the cost of investment securities for tax purposes was $2,338,065,000. Net unrealized appreciation of investment securities for tax purposes was $263,993,000, consisting of unrealized gains of $394,561,000 on securities that had risen in value since their purchase and $130,568,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2012, the fund purchased $1,595,861,000 of investment securities and sold $1,438,434,000 of investment securities, other than temporary cash investments. Purchases and sales include $461,821,000 and $506,452,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

G. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced an upcoming change in the fund’s benchmark index from the MSCI US Mid Cap Growth Index to the CRSP US Mid Cap Growth Index. The fund’s investment objective is not changing. The transition to the new benchmark is expected to be completed over several months, and will require some turnover of holdings with resulting transaction costs. Vanguard will seek to minimize trading impact through efficient portfolio trading.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $313,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.13% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Mid-Cap Value Index Fund

At December 31, 2012, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

During the year ended December 31, 2012, the fund realized $58,057,000 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, 2012, the fund had $613,000 of ordinary income available for distribution. At December 31, 2012, the fund had available capital losses totaling $145,970,000 to offset future net capital gains. Of this amount, $139,259,000 is subject to expiration dates; $75,804,000 may be used to offset future net capital gains through December 31, 2017, and $63,455,000 through December 31, 2018. Capital losses of $6,711,000 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, 2012, the cost of investment securities for tax purposes was $2,190,455,000. Net unrealized appreciation of investment securities for tax purposes was $176,092,000, consisting of unrealized gains of $259,519,000 on securities that had risen in value since their purchase and $83,427,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2012, the fund purchased $1,471,672,000 of investment securities and sold $845,818,000 of investment securities, other than temporary cash investments. Purchases and sales include $462,310,000 and $212,885,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

1 Inception was September 27, 2011, for Admiral Shares.

G. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced an upcoming change in the fund’s benchmark index from the MSCI US Mid Cap Value Index to the CRSP US Mid Cap Value Index. The fund’s investment objective is not changing. The transition to the new benchmark is expected to be completed over several months, and will require some turnover of holdings with resulting transaction costs. Vanguard will seek to minimize trading impact through efficient portfolio trading.

Report of Independent Registered
Public Accounting Firm

To the Trustees of Vanguard Index Funds and the Shareholders of Vanguard Extended Market Index Fund, Vanguard Mid-Cap Index Fund, Vanguard Mid-Cap Growth Index Fund and Vanguard Mid-Cap Value Index Fund: In our opinion, the accompanying statement of net assets—investments summary and statements of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Extended Market Index Fund, Vanguard Mid-Cap Index Fund, Vanguard Mid-Cap Growth Index Fund and Vanguard Mid-Cap Value Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2012, the results of each of their operations for the year then ended, the changes in each of their net assets and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2012 by correspondence with the custodians and broker and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

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, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, 0.06% for Institutional Plus Shares, and 0.10% for ETF Shares; for the Mid-Cap Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, 0.06% for Institutional Plus Shares, and 0.10% for ETF Shares; for the Mid-Cap Growth Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, and 0.10% for ETF Shares; and for the Mid-Cap Value Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, and 0.10% for ETF 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.

Chairman’s Letter

Dear Shareholder,

Vanguard’s three large-capitalization stock index funds produced strong returns for 2012, as U.S. stocks bounced back from a lackluster 2011.

For the fiscal year ended December 31, 2012, Vanguard Growth Index Fund returned 16.89%, outpacing Vanguard Value Index Fund’s 15.00% return. Vanguard Large-Cap Index Fund, which includes both growth and value stocks, fell in between, returning 15.94%. (All returns are for the funds’ Investor Shares.)

All three funds closely tracked their target indexes for the year. Vanguard Large-Cap Index Fund and the Growth Index Fund surpassed the average returns of their respective peer groups; the Value Index Fund trailed its peer-group average.

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

European stocks shook off investors’ concerns to deliver some of the best results, rising about 19% compared with about 16% for U.S. stocks. The rally came as European central bankers moved to

address worries about the finances of governments and banks. Still, Vanguard economists expect Europe to remain a trouble spot, with occasional spikes in market volatility, as fiscal tightening persists in the face of weak economic growth.

In the United States, the Federal Reserve continued buying bonds and mortgage-backed securities to try to stimulate growth. The Fed’s actions seemed to buoy both stock and bond returns.

Bond returns were solid, but challenges lie ahead
The broad U.S. taxable bond market returned about 4% for the 12 months. Municipal bonds performed especially well, returning more than 6%.

As bond prices rose, the yield of the 10-year U.S. Treasury note slipped to a record low in July, closing below 1.5%. (Bond yields and prices move in opposite

directions.) By the end of the period, the yield had climbed, but it remained exceptionally low by historical standards.

Although bonds can provide critical diversification benefits to a portfolio, their prospects look much less promising than the results achieved in recent years. As yields have tumbled, the opportunity for future bond price appreciation has greatly diminished. (You can read more about our expectations for bond and stock returns in Vanguard’s Economic and Investment Outlook, available at vanguard.com/ research.)

As it has since late 2008, the Fed held its target for short-term interest rates between 0% and 0.25%, which kept a tight lid on returns from money market funds and savings accounts.

Growth stocks topped the large-cap category
The broad U.S. stock market began the year with its best first-quarter performance in more than a decade. With the U.S. economy showing promising growth and the European debt crisis seemingly under control, large-cap stocks of all styles rose in the first half of the year.

The fund expense ratios shown are from the prospectus dated April 26, 2012, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2012, the funds’ expense ratios were: for the Growth Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; for the Value Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; and for the Large-Cap Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares. The peer-group expense ratios are derived from data provided by Lipper Inc. and capture information through year-end 2011.

Peer groups: For the Growth Index Fund, Large-Cap Growth Funds; for the Value Index Fund, Large-Cap Value Funds; for the Large-Cap Index Fund, Large-Cap Core Funds.

However, it was far from smooth sailing the rest of the year. Stocks in the United States and abroad rose and fell amid renewed concerns about the U.S. economy and the future of the Eurozone. Still, large-cap stocks maintained their earlier gains and ended the year with a much stronger performance than a year ago, when returns hovered around 1%.

The Growth Index Fund benefited most from its outsized allocation to information technology stocks, which contributed a third of its return for the period. Computer hardware companies did exceptionally well, thanks to consumers’ seemingly unquenchable thirst for smartphones and tablet computers. The fund’s consumer discretionary stocks, such as media companies, also turned in impressive results. In health care, biotech firms, health care equipment suppliers, and service providers delivered strong results.

The Large-Cap Index Fund also benefited from its large allotment to tech (albeit a smaller proportion than that of the Growth Index Fund) and consumer discretionary

stocks. The fund’s biggest gains came from financials, which enjoyed a remarkable turnaround in performance from a year ago. Banks and other diversified financial services providers returned nearly 30% as capital levels rose, lending improved, and the U.S. housing market continued its recovery.

As I mentioned, the Value Index Fund trailed the other two funds but still produced a gain of about 15%. Its largest sector holding, financials, contributed most to its returns. The Value Index’s weakest sector overall was information technology, which returned –3% for the period. Because the fund’s target benchmark only focuses on value-oriented tech stocks, the fund didn’t hold some of the best performers in the sector, including makers of smartphones and tablet computers. Instead it was saddled with the stocks of weaker-performing personal computer, office electronics, and semiconductor manufacturers.

The funds have produced a solid long-term record
For the decade ended December 31, 2012, the Growth Index Fund and the Value Index Fund recorded average annual returns of 7.36% and 7.33%, respectively. The Large-Cap Index Fund, which does not yet have a full decade of performance, has posted an average annual return of 5.05% since its inception in early 2004.

Each of the three large-cap funds has tracked its index closely, even though the benchmarks’ returns reflect no operating or transaction costs. In addition, each fund’s average annual return has surpassed that of its peer group.

The funds’ success in this regard is a tribute to their investment advisor, Vanguard Equity Investment Group, whose sophisticated portfolio construction and management techniques reflect more than 30 years of indexing experience. The advisor has been aided in this task by each fund’s low expenses.

Funds will seek to track new benchmark indexes
In early October, we announced that the three funds in this report would adopt new target benchmarks as part of a broader transition affecting 22 of our index funds. This transition, which we plan to complete by the middle of the year, is expected to produce significant long-term savings for Vanguard clients. As of January 31, we had already completed the transition for Vanguard Large-Cap Index Fund.

Gus Sauter united traditional values with pioneering investment acumen
When I was interviewing for a job at Vanguard in the mid-1980s, Jack Brennan, who would go on to become our chairman and CEO and is now chairman emeritus, described Vanguard as “a company with the intellectual rigor of Wall Street but with Midwestern values.”

As for the Midwestern values, Gus—a native of Ohio, incidentally—served our clients with a dedication to thrift, candor, and common sense that has helped make Vanguard what it is. His colleagues knew that in any situation they could count on Gus to keep a level-headed, long-term outlook. Just two weeks after he started at Vanguard, Gus helped guide us through the stock market crash of 1987. Some 20 years later, he helped us navigate the financial crisis of 2008–2009.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Notes to Financial Statements

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

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

Growth Index Fund

capital of $3,710,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.48% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At December 31, 2012, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

During the year ended December 31, 2012, the fund realized $275,174,000 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, 2012, the fund had $4,372,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $194,220,000 to offset capital gains realized during the year ended December 31, 2012. At December 31, 2012, the fund had available capital losses totaling $1,007,038,000 to offset future net capital gains. Of this amount, $802,533,000 is subject to expiration on December 31, 2017. Capital losses of $204,505,000 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, 2012, the cost of investment securities for tax purposes was $20,576,556,000. Net unrealized appreciation of investment securities for tax purposes was $6,543,214,000, consisting of unrealized gains of $6,969,544,000 on securities that had risen in value since their purchase and $426,330,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2012, the fund purchased $9,397,727,000 of investment securities and sold $6,465,359,000 of investment securities, other than temporary cash investments. Purchases and sales include $2,723,029,000 and $1,255,980,000 respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

G. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced an upcoming change in the fund’s benchmark index from the MSCI US Prime Market Growth Index to the CRSP US Large Cap Growth Index. The fund’s investment objective is not changing. The transition to the new benchmark is expected to be completed over several months, and will require some turnover of holdings with resulting transaction costs. Vanguard will seek to minimize trading impact through efficient portfolio trading.

At December 31, 2012, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

During the year ended December 31, 2012, the fund realized $524,026,000 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, 2012, the fund had $4,414,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $67,045,000 to offset taxable capital gains realized during the year ended December 31, 2012. At December 31, 2012, the fund had available capital losses totaling $1,525,636,000 to offset future net capital gains. Of this amount, $1,518,501,000 is subject to expiration on December 31, 2017. Capital losses of $7,135,000 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, 2012, the cost of investment securities for tax purposes was $17,833,939,000. Net unrealized appreciation of investment securities for tax purposes was $610,759,000, consisting of unrealized gains of $2,019,083,000 on securities that had risen in value since their purchase and $1,408,324,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2012, the fund purchased $7,331,815,000 of investment securities and sold $5,631,612,000 of investment securities, other than temporary cash investments. Purchases and sales include $3,217,619,000 and $1,906,998,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

G. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced an upcoming change in the fund’s benchmark index from the MSCI US Prime Market Value Index to the CRSP US Large Cap Value Index. The fund’s investment objective is not changing. The transition to the new benchmark is expected to be completed over several months, and will require some turnover of holdings with resulting transaction costs. Vanguard will seek to minimize trading impact through efficient portfolio trading.

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

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

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

Large-Cap Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2012, the fund had contributed capital of $864,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.35% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	6,222,942	—	—
Temporary Cash Investments	15,785	700	—
Futures Contracts—Assets¹	351	—	—
Futures Contracts—Liabilities¹	(18)	—	—
Total	6,239,060	700	—
1 Represents variation margin on the last day of the reporting period.

Large-Cap Index Fund

D. At December 31, 2012, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
S&P 500 Index	March 2013	35	12,426	36

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

During the year ended December 31, 2012, the fund realized $17,082,000 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, 2012, the fund had $1,340,000 of ordinary income available for distribution. At December 31, 2012, the fund had available capital losses totaling $212,938,000 to offset future net capital gains. Of this amount, $194,830,000 is subject to expiration dates; $43,673,000 may be used to offset future net capital gains through December 31, 2016, $117,390,000 through December 31, 2017, and $33,767,000 through December 31, 2018. Capital losses of $18,108,000 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, 2012, the cost of investment securities for tax purposes was $5,147,796,000.

Net unrealized appreciation of investment securities for tax purposes was $1,091,631,000, consisting of unrealized gains of $1,403,041,000 on securities that had risen in value since their purchase and $311,410,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2012, the fund purchased $887,010,000 of investment securities and sold $495,765,000 of investment securities, other than temporary cash investments. Purchases and sales include $182,675,000 and $42,221,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

H. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced a change in the fund’s benchmark index from the MSCI US Prime Market 750 Index to the CRSP US Large Cap Index. The benchmark change was effective on January 31, 2013. The fund’s investment objective has not changed.

Report of Independent Registered
Public Accounting Firm

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

In our opinion, the accompanying statements of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Growth Index Fund, Vanguard Value Index Fund and Vanguard Large-Cap Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2012, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2012 by correspondence with the custodians and broker and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Special 2012 tax information (unaudited) for Vanguard U.S. Stock Index Funds (Large-Capitalization Portfolios)

This information for the fiscal year ended December 31, 2012, is included pursuant to provisions of the Internal Revenue Code.

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


	Qualified Dividend Income
Fund	($000)
Growth Index Fund	390,721
Value Index Fund	482,481
Large-Cap Index Fund	128,611

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


Fund	Percentage
Growth Index Fund	100.0%
Value Index Fund	95.2
Large-Cap Index Fund	97.1

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.)

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

Institutional Shares	1,000.00	1,024.80	0.41
ETF Shares	1,000.00	1,024.70	0.51

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, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; for the Value Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; and for the Large-Cap Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF 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.

Chairman’s Letter

Dear Shareholder,

The broad U.S. stock market rode out political, economic, and fiscal uncertainty to end the year with solid returns. Twice, it seemed poised to tumble as concern flared in the spring and fall over all-too-familiar woes: the economy’s sluggish recovery, Europe’s debt predicament, Asia’s slowdown, and Washington’s fiscal gridlock. Yet throughout, the market managed to stay in positive territory.

Vanguard Total Stock Market Index Fund closely tracked its benchmark, the MSCI US Broad Market Index, which gained more than 16% for the year. The fund’s peers returned close to 15% on average.

If you own the fund in a taxable account, you may wish to review the information on after-tax returns presented later in this report.

market volatility, as fiscal tightening persists in the face of weak economic growth.

In the United States, the Federal Reserve continued buying bonds and mortgage-backed securities to try to stimulate growth. The Fed’s actions seemed to buoy both stock and bond returns.

Attention to the nation’s considerable budget challenges intensified as 2012 drew to a close. The focus on the “fiscal cliff” led to anxiety in the markets before policymakers reached a limited tax-rate agreement on the cusp of the new year. The compromise legislation, which President Barack Obama signed into law on January 2, addressed some immediate

concerns, but a credible long-term deficit-reduction strategy had yet to be crafted to resolve the nation’s fiscal imbalance and open the way for growth.

Bond returns were solid, but challenges lie ahead
The broad U.S. taxable bond market returned about 4% for the 12 months. Municipal bonds performed especially well, returning more than 6%.

Although bonds can provide critical diversification benefits to a portfolio, their prospects look much less promising than the returns achieved in recent years. As yields have tumbled, the opportunity for future bond price appreciation has greatly diminished. (You can read more about our expectations for bond and stock returns in Vanguard’s Economic and Investment Outlook, available at vanguard.com/ research.)

As it has since late 2008, the Fed held its target for short-term interest rates between 0% and 0.25%, which kept a tight lid on returns from money market funds and savings accounts.

Consumer discretionary and bank stocks led sector returns
Vanguard Total Stock Market Index Fund benefited from robust returns across much of the business landscape. While overall economic growth remained modest in 2012, the improving housing market and low interest rates were notable tonics.

Investors saw particular value in banks and in firms involved in the production and sale of discretionary consumer goods and services—two sectors heavily represented in the fund. As demand for homes picked up, investors bid up stocks related to the various nonessentials—things like new cars, TVs, cable hookups—that often go with homeownership and better times in general.

Peer group: Multi-Cap Core Funds.

This heartier investor appetite for stocks associated with economic expansion meant a modest performance for utilities stocks, which are often considered recession-resistant. Utilities’ small weighting in the fund muted the effect of their relative weakness.

Energy stocks also underperformed. Energy companies’ earnings fell in the spring as oil prices slumped amid new supplies and concern that the U.S. and global economies were about to slow sharply.

Solid long-term performance through a difficult decade
Over the past decade, Investor Shares of Vanguard Total Stock Market Index Fund had an annual average return of 7.83%, closely tracking the fund’s broad-market benchmark, which returned 7.96%. For the decade, the fund outperformed the average return of its peers by more than 1 percentage point.

Your fund will seek to track a new benchmark index
In early October, we announced that Vanguard Total Stock Market Index Fund would adopt a new target benchmark as part of a broader transition affecting 22 of our index funds. This transition, which we plan to complete by the middle of the year, is expected to produce significant long-term savings for Vanguard clients.

The new benchmark for the fund will be supplied by the University of Chicago’s Center for Research in Security Prices

Gus Sauter united traditional values with pioneering investment acumen
When I was interviewing for a job at Vanguard in the mid-1980s, Jack Brennan, who would go on to become our chairman and CEO and now chairman emeritus, described Vanguard as “a company with the intellectual rigor of Wall Street but with Midwestern values.”

A note on expense ratios

The Expense Ratios table in each report’s Chairman’s Letter displays fund expense

ratios from the most recent prospectus. These figures include the funds’ actual

operating expenses. For some funds, the figures also include “acquired fund fees

and expenses,” which result from the funds’ holdings in business development

companies (BDCs).

Although the Securities and Exchange Commission requires that BDC costs be

included in a fund’s expense ratio, these fees are not incurred by the fund. They

have no impact on a fund’s total return or on its tracking error relative to an index.

A footnote to the Expense Ratios table reports an annualized calculation of the fund’s

actual expenses for the period, a more relevant tally of the operating costs incurred

by shareholders.

Vanguard, he helped guide us through the stock market crash of 1987. Some 20 years later, he helped us navigate the financial crisis of 2008–2009.

An important aspect of Gus’s legacy is the team of world-class investment professionals that he cultivated at Vanguard. That team is now led by Tim Buckley, who led our services for individual investors before becoming chief investment officer. I am confident that Tim will not only carry on Gus’s legacy, but also—as Gus himself put it—take Vanguard investment management to the next level.

As always, thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Total Stock Market Index Fund

Notes to Financial Statements

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

Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

During the year ended December 31, 2012, the fund’s average investment in futures contracts represented less than 1% of net assets, based on quarterly average aggregate settlement values.

3. Swap Contracts: The fund has entered into an equity swap contract to earn the total return on a selected reference stock in the fund’s target index. Under the terms of the swap, 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 as unrealized appreciation (depreciation) until termination of the swap, at which time realized gain (loss) is recorded. The primary risks associated with the swaps are that a counterparty will default on its obligation to pay net amounts due to the fund, or that the fund will incur fees in the event it terminates a swap prior to the scheduled termination date. The fund’s maximum risk of loss from counterparty credit risk is the amount of unrealized appreciation on the swap contract. The fund attempts to mitigate this risk by, among other things, performing a credit analysis of counterparties, monitoring exposure to counterparties, and by requiring counterparties to post collateral to secure such exposure. The swap contracts contain provisions whereby a counterparty may terminate open contracts if the fund’s 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 posted. Any securities posted as collateral for open contracts are noted in the Statement of Net Assets.

During the year ended December 31, 2012, the fund’s average investment in swap contracts represented less than 1% of net assets, based on quarterly average notional amounts.

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, 2009–2012), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

6. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

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. 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.

Total Stock Market Index Fund

contributed capital of $28,242,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 11.30% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments).

The following table summarizes the market value of the fund’s investments as of December 31, 2012, based on the inputs used to value them:

S&P MidCap 400 Index	March 2013	280	28,507	(148)

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

Total Stock Market Index Fund

At December 31, 2012, the fund had the following open swap contracts:


				Floating	Unrealized
			Notional	Interest Rate	Appreciation
	Termination		Amount	Received	(Depreciation)
Reference Entity	Date	Counterparty¹	($000)	(Paid)	($000)

1 GSI—Goldman Sachs International.
2 Based on one-month London Interbank Offered Rate (LIBOR) as of the most recent payment date plus a 0.35% spread.

At December 31, 2012, the counterparty had deposited in segregated accounts securities with a value of $3,051,000 in connection with amounts due to the fund for open swap contracts.

During the year ended December 31, 2012, the fund realized $2,520,489,000 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, 2012, the fund had $48,233,000 of ordinary income available for distribution. At December 31, 2012, the fund had available capital losses totaling $3,200,440,000 to offset future net capital gains. Of this amount, $2,492,045,000 is subject to expiration dates; $209,043,000 may be used to offset future net capital gains through December 31, 2013, $19,516,000 through December 31, 2015, and $2,263,486,000 through December 31, 2016. Capital losses of $708,395,000 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, 2012, the cost of investment securities for tax purposes was $176,868,895,000. Net unrealized appreciation of investment securities for tax purposes was $34,252,472,000, consisting of unrealized gains of $48,476,493,000 on securities that had risen in value since their purchase and $14,224,021,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2012, the fund purchased $30,237,841,000 of investment securities and sold $10,597,709,000 of investment securities, other than temporary cash investments. Purchases and sales include $4,870,345,000 and $4,576,905,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

H. In preparing the financial statements as of December 31, 2012, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

On October 2, 2012, Vanguard announced an upcoming change in the fund’s benchmark index from the MSCI US Broad Market Index to the CRSP US Total Market Index. The fund’s investment objective is not changing. The transition to the new benchmark is expected to be completed over several months, and will require some turnover of holdings with resulting transaction costs. Vanguard will seek to minimize trading impact through efficient portfolio trading.

To the Trustees of Vanguard Index Funds and the Shareholders of Vanguard Total Stock Market Index Fund: In our opinion, the statement of net assets–investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Total Stock Market Index Fund (constituting a separate portfolio of Vanguard Index Funds, hereafter referred to as the “Fund”) at December 31, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2012 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Institutional Shares	1,000.00	1,064.57	0.21
ETF Shares	1,000.00	1,064.31	0.26

Admiral Shares	1,000.00	1,024.95	0.26
Signal Shares	1,000.00	1,024.95	0.26
Institutional Shares	1,000.00	1,025.00	0.20
ETF Shares	1,000.00	1,024.95	0.26

The calculations are based on expenses incurred in the most recent six-month period.

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.
