Chairman’s Letter

Dear Shareholder,

Despite the frustratingly slow pace of post-recession growth, the United States economy continues to move forward. This has raised the possibility that the Federal Reserve might increase short-term interest rates, after anchoring them in the neighborhood of zero more than five years ago. The current consensus is that a rate increase isn’t likely to occur until sometime in 2015, although that depends, of course, on economic circumstances and the Fed’s assessment of them, both of which are subject to change.

For now, the returns of Vanguard’s money market funds continue to be restrained by the Fed’s policy. Vanguard Prime Money Market Fund, Admiral Treasury Money Market Fund, and Federal Money Market Fund each returned 0.01% for the six months ended February 28, 2014. (Because of their lower costs, Institutional Shares of the Prime Money Market Fund returned 0.03%.) The average return of peer-group funds was 0.00%. Despite the low returns, the funds continued to carry out their primary goal of investing in money market assets of superior credit quality.

The funds’ 7-day SEC yields were similar to what they were six months ago. The yields for the Admiral Treasury Money Market Fund and the Investor Shares of the Prime Money Market Fund finished the period where they started it, at 0.01%; the yield for the Federal Money Market Fund dipped slightly, from 0.02% to

0.01%; and the yield for the Prime Money Market Fund’s Institutional Shares increased from 0.04% to 0.06%.

Before going on to discuss the markets, I want to mention an important transition at Vanguard. We announced last autumn that Robert F. Auwaerter, principal and head of Vanguard Fixed Income Group, intended to retire this spring. Later in this letter, I’ll have more to say about Bob’s important contributions to Vanguard during his 32-year career, and I’ll introduce his successor, Gregory Davis.

Bonds staged a rebound after last year’s swoon
The Fed’s policy on short-term rates has been accompanied by a massive bond-buying program aimed at lowering longer-term rates. (This program has, of course, had little effect on money market funds.) Beginning in January, the central bank began scaling back its monthly bond purchases. Bonds had slumped notably in 2013 as investors worried about the future of the Fed’s program, but they nevertheless delivered solid results for the six months. The broad U.S. taxable bond

market returned 2.84%, as the yield of the benchmark 10-year Treasury note finished the six months at 2.64%, down from 2.76% at the end of August. (Bond prices and yields move in opposite directions.)

Municipal bonds, which had declined sharply in the fiscal year ended August 31, regained some ground, returning 5.71%. The market had been roiled during the summer by headlines about Detroit’s bankruptcy and Puerto Rico’s fiscal woes, but as the headlines receded, investors seemed to take a more comprehensive view of state and local finances. Our chief investment officer, Tim Buckley, noted recently that, on the whole, “municipalities out there are actually doing a lot better than they were a few years ago.”

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned 4.93%.

Mostly positive factors lifted U.S. stock markets
Favorable corporate earnings, generally positive economic news, improved investor sentiment, and the Fed’s accommodative bond-buying program—all of these factors helped the broad U.S. stock market post a strong six-month return of about 16%.

International stocks, in aggregate, returned about 12%. Most of the strength came from the developed markets of Europe. The developed markets of the Pacific region managed single-digit returns for the period, as did emerging markets,

Prime Money Market Fund	0.17%	0.10%	0.23%
Federal Money Market Fund	0.14	—	0.14

The fund expense ratios shown are from the prospectus dated December 23, 2013, and represent estimated costs for the current fiscal year. For the six months ended February 28, 2014, the funds’ annualized expense ratios were: for the Prime Money Market Fund, 0.14% for Investor Shares and 0.10% for Institutional Shares; for the Federal Money Market Fund, 0.10%; for the Admiral Treasury Money Market Fund, 0.06%. The expense ratios for the six months ended February 28, 2014, for the Prime Money Market Fund Investor Shares, the Federal Money Market Fund, and the Admiral Treasury Money Market Fund reflect a temporary reduction in operating expenses (described in Note B of the Notes to Financial Statements). Before the reduction, the expense ratios were: for the Prime Money Market Fund Investor Shares, 0.16%; for the Federal Money Market Fund, 0.11%; for the Admiral Treasury Money Market Fund, 0.09%.

Peer groups: For the Prime Money Market Fund, Money Market Funds; for the Federal Money Market Fund, Government Money Market Funds; and for the Admiral Treasury Money Market Fund, U.S. Treasury Money Market Funds. In most, if not all, cases, the expense ratios for funds in the peer groups are based on net operating expenses after reimbursement and/or fee waivers by fund sponsors. In contrast, the Vanguard money market funds’ expense ratios in the table above do not reflect expense reductions.

which have seen particularly volatile results amid concerns about China’s slowing economy and the effects of interest rate changes as the Fed winds down its stimulus.

The advisor has made selective investments in Europe
In making its investments, the Vanguard Money Market Funds take a conservative stance—investing only in money market securities that are rated in one of the two highest credit-quality categories (as determined by nationally recognized credit-rating services). Treasury securities are, of course, backed by the full faith and credit of the United States and are the “go-to” asset whenever investors become more fearful about economic and market events. Federal agency securities, the focus of the Federal Money Market Fund, have virtually the same credit quality as securities issued by the U.S. government.

For securities issued by banks and corporations, the ultimate decision on which securities to purchase is based on the portfolio manager’s independent analysis of the financial strength of issuers. A key component of that analysis is the quality of a bank’s capital, which serves as a reserve against losses.

Treasuries and other U.S. government obligations accounted for almost 40% of the Prime Money Market Fund’s assets,

as of February 28. About 40% consisted of certificates of deposits issued by banks, and about 20% was in commercial paper (a form of short-term loan) issued by both banks and corporations.

The geographical diversity of the fund’s bank CD and commercial paper investments widened beyond the United States, Australia, and Canada during the period. The fund reentered the European market in the fall, and exposure to European banks grew to about 24% of assets as of February 28. Although Europe continues to face economic challenges, some improvements have occurred, aided by the expansionary policies of the European Central Bank and the Bank of England. This, along with notable improvements in banks’ capital positions, led the portfolio manager to selectively increase the fund’s exposure to CDs and commercial paper issued by banking institutions in the United Kingdom, Norway, Sweden, Switzerland, and the Netherlands. (Overseas investments are denominated in U.S. dollars.)

Bob Auwaerter’s retirement marks the end of a remarkable era
In mid-September 2008, about two weeks after I succeeded Jack Brennan as Vanguard’s chief executive officer, Lehman Brothers went bankrupt, igniting the nation’s worst financial crisis in 70 years. It was, to put it mildly, an extremely challenging time. Through it all, I was able to depend on Bob Auwaerter’s strong command of the Fixed Income Group, which persevered under these treacherous conditions. Although that was a difficult period for Vanguard and the industry, it was far from the only time I was grateful to have Bob at the helm of our bond group.

Bob, who joined Vanguard in 1981, was an original member of the three-person Fixed Income Group, headed by Ian MacKinnon. Over the years, Bob held various leadership roles in the department, and he eventually succeeded Ian as its head in 2003. He earned a reputation at Vanguard and within the industry as an extremely dedicated, honest, and insightful decision-maker and leader.

The Fixed Income Group that Bob helped start had initial total assets of about $1.3 billion in seven funds. He tracked his positions in the two funds he managed then on index cards stored in a small metal box. Thirty-two years later, the 120-person group oversees $750 billion, which represents nearly one-third of Vanguard’s assets under management.

On behalf of our clients, I thank Bob for more than three decades of exemplary service and wish him the best in his retirement.

We’re fortunate that Greg Davis will become the head of the Fixed Income Group. Greg currently serves as chief investment officer for the Asia Pacific region and as a director of Vanguard Investments Australia. He joined Vanguard in 1999 and had been head of bond indexing and a senior portfolio

manager in the Fixed Income Group. Greg is an eminently qualified successor and has a strong commitment to the Vanguard way of investing. I couldn’t be more confident in his ability to lead the Fixed Income Group and its deep and talented team.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Advisor’s Report

For the six months ended February 28, 2014, the Investor Shares of Vanguard Prime Money Market Fund returned 0.01%, and the Institutional Shares returned 0.03%, a consequence of their lower expense ratio. The Federal Money Market Fund and the Admiral Treasury Fund both returned 0.01%. The average return for each fund’s peer group was 0%.

The economic and market environment
Short-term interest rates have remained at rock bottom levels since the Federal Reserve set its target interest rate between 0% and 0.25% in December 2008. (This rate, known as the federal funds rate, applies to overnight lending between banks and can be influenced easily by the central bank.) Fortunately, we are seeing improving trends in GDP that may lead to a pickup in the pace of job growth. With inflation appearing to be under control, a sustained resurgence in job growth is the one element that has eluded the Fed.

What will this mean for money market yields? Unfortunately, our forecast is for money market rates to remain at rock-bottom levels throughout 2014. After such a prolonged period of economic weakness, the Fed may be reluctant to raise rates too quickly, preferring to look for confirmation of a sustained recovery.

Before the Fed returns to using more traditional monetary policy tools, it needs to close out its quantitative easing program, which was part of the extraordinary measures implemented to stimulate the economy during the financial crisis. The Fed recently took steps to this end by gradually tapering the size of the program. We anticipate the tapering phase to be completed sometime in the fall of 2014.

Management of the funds
We continue to seek the best opportunities available in the market for U.S. Treasury and federal agency securities, which are the focus of the Admiral Treasury and Federal Money Market Funds. The Prime Money Market Fund has a wider investment mandate; it invests not only in Treasuries and agencies but also in private-sector securities, including certificates of deposit and commercial paper.

Within the global banking sector, capital positions have strengthened in response to stiffer regulatory requirements in the aftermath of the financial crisis. Our credit team has been closely monitoring these conditions as one of many factors it uses to analyze the strength of an issuer. In some cases the team’s analysis has confirmed the renewed strength brought about by regulatory reforms and has led it to recommend bringing back some credits that were sidelined a few years ago. These include, for example, CDs and commercial paper issued by banks in the United Kingdom and Northern Europe.

Credit analysis is a dynamic process, in particular for money market funds, where safety and liquidity are the highest priorities. I’m especially proud of our credit analysts’

8

performance during the financial crisis. The decisions they made steered us clear of the risks that others failed to see. They are the unsung heroes who work behind the scenes but play a critical role in managing your assets.

The reporting period was also marked by innovation: The Treasury issued two-year floating-rate notes, and the Federal Reserve began a pilot program involving overnight repurchase agreements. We declined to invest in the floating-rate notes, which have a variable interest rate that is pegged to a benchmark, in their first auctions in January and February because we thought prices were too high. We expect that these notes will be part of our asset mix in the future, but only when the price is right.

The repurchase agreements, or “repos,” are similar to other repo transactions we enter into, except that the counterparty to the transaction is the Federal Reserve. From a credit quality perspective, we’re excited to have an opportunity to invest with the Fed and expect these transactions to become an important component of the Prime and Federal Money Market Funds asset mix in the future.

Outlook for money market reforms
Since the financial crisis, the money market industry has been undergoing a variety of reforms aimed at further strengthening the stability and safety of its funds. In the pipeline are additional proposals from the U.S. Securities and Exchange Commission that go beyond what it has previously adopted. As we have noted before, we welcome the commission’s efforts and the opportunity to review and comment on its proposals. In doing so, our paramount goal has been to ensure that your interests are represented.

(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.) The returns shown do not reflect taxes that a shareholder would pay on fund distributions. An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Prime Money Market Fund

Notes to Financial Statements

Vanguard Prime Money Market Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in short-term debt instruments of companies primarily operating in specific industries, particularly financial services; the issuers’ abilities to meet their obligations may be affected by economic developments in such industries. The fund offers two classes of shares, Investor Shares and Institutional Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Institutional Shares are designed for institutional investors who meet certain administrative, service, and account-size criteria.

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

1. Security Valuation: Securities are valued at amortized cost, which approximates market value. Investments in Vanguard Municipal Cash Management Fund are valued at that fund’s net asset value.

2. Repurchase Agreements: The fund enters into repurchase agreements with institutional counter-parties. Securities pledged as collateral to the fund under repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. The fund further mitigates its counterparty risk by entering into repurchase agreements only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master repurchase agreements with its counterparties. The master repurchase agreements provide that, in the event of a counter-party’s default (including bankruptcy), the fund may terminate any repurchase agreements with that counterparty, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund. Such action may be subject to legal proceedings, which may delay or limit the disposition of collateral. The fund had no open repurchase agreements at February 28, 2014.

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 (August 31, 2010–2013), and for the period ended February 28, 2014, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

4. Distributions: Distributions from net investment income are declared daily and paid on the first business day of the following month.

5. Other: Interest income includes income distributions received from Vanguard Municipal Cash Management Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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

B. 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

27

Prime Money Market Fund

net assets in capital contributions to Vanguard. At February 28, 2014, the fund had contributed capital of $14,643,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 5.86% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard. Vanguard and the board of trustees have agreed to temporarily limit certain net operating expenses in excess of the fund’s daily yield so as to maintain a zero or positive yield for the fund. Vanguard and the board of trustees may terminate the temporary expense limitation at any time. For the period ended February 28, 2014, Vanguard’s expenses allocated to the Investor Shares were reduced by $9,154,000 (an effective annual rate of 0.02% of the average net assets of the Investor Shares class).

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 fund’s investment in Vanguard Municipal Cash Management Fund is valued based on Level 1 inputs. All of the fund’s other investments were valued using amortized cost, in accordance with rules under the Investment Company Act of 1940. Amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, securities valued at amortized cost are considered to be valued using Level 2 inputs.

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

Notes to Financial Statements

Vanguard Federal Money Market Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in short-term debt instruments issued by the U.S. government or its agencies and instrumentalities, and repurchase agreements collateralized by such instruments.

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 at amortized cost, which approximates market value.

2. Repurchase Agreements: The fund enters into repurchase agreements with institutional counterparties. Securities pledged as collateral to the fund under repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. The fund further mitigates its counterparty risk by entering into repurchase agreements only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master repurchase agreements with its counterparties. The master repurchase agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any repurchase agreements with that counterparty, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund. Such action may be subject to legal proceedings, which may delay or limit the disposition of collateral.

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 (August 31, 2010–2013), and for the period ended February 28, 2014, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

4. Distributions: Distributions from net investment income are declared daily and paid on the first business day of the following month.

5. Other: Interest income is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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 February 28, 2014, the fund had contributed capital of $369,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.15% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard. Vanguard and the board of trustees have agreed to temporarily limit certain net operating expenses in excess of the fund’s daily yield so as to maintain a zero or positive yield for the fund. Vanguard and the board of trustees may terminate the temporary expense limitation at any time. For the period ended February 28, 2014, Vanguard’s expenses were reduced by $249,000 (an effective annual rate of 0.01% of the fund’s average net assets).

38

Federal Money Market Fund

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).

At February 28, 2014, 100% of the market value of the fund’s investments was determined using amortized cost, in accordance with rules under the Investment Company Act of 1940. Amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, securities valued at amortized cost are considered to be valued using Level 2 inputs.

D. Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

Performance Summary

Investment returns will fluctuate. All of the returns in this report represent past performance, which is not a guarantee of future results that may be achieved by the fund. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our website at vanguard.com/performance.) The returns shown do not reflect taxes that a shareholder would pay on fund distributions. An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1 per share, it is possible to lose money by investing in the fund. The fund’s 7-day SEC yield reflects its current earnings more closely than do the average annual returns.

Admiral Treasury Money Market Fund

Notes to Financial Statements

Vanguard Admiral Treasury Money Market Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in short-term debt instruments backed by the full faith and credit of the U.S. government.

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 at amortized cost, which approximates market value.

2. 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 (August 31, 2010–2013), and for the period ended February 28, 2014, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

3. Distributions: Distributions from net investment income are declared daily and paid on the first business day of the following month.

4. Other: Interest income is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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 February 28, 2014, the fund had contributed capital of $1,233,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.49% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard. Vanguard and the board of trustees have agreed to temporarily limit certain net operating expenses in excess of the fund’s daily yield so as to maintain a zero or positive yield for the fund. Vanguard and the board of trustees may terminate the temporary expense limitation at any time. For the period ended February 28, 2014, Vanguard’s expenses were reduced by $1,956,000 (an effective annual rate of 0.03% of the fund’s average net assets).

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).

47

Admiral Treasury Money Market Fund

At February 28, 2014, 100% of the market value of the fund’s investments was determined using amortized cost, in accordance with rules under the Investment Company Act of 1940. Amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, securities valued at amortized cost are considered to be valued using Level 2 inputs.

D. Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

48

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.

Admiral Treasury Money Market Fund	$1,000.00	$1,024.50	$0.30

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for the period are: for the Prime Money Market Fund, 0.14% for Investor Shares and 0.10% for Institutional Shares; for the Federal Money Market Fund, 0.10%; and for the Admiral Treasury Money Market Fund, 0.06%. The annualized six-month expense ratios for the Prime Money Market Fund Investor Shares, the Federal Money Market Fund, and the Admiral Treasury Money Market Fund reflect a temporary reduction in operating expenses (described in Note B of the Notes to Financial Statements). Before the reduction, the annualized six-month expense ratios were: for the Prime Money Market Fund Investor Shares, 0.16%; for the Federal Money Market Fund, 0.11%; for the Admiral Treasury Money Market Fund, 0.09%.

Glossary

SEC Yields. A money market fund’s 7-day SEC yield is calculated by annualizing its income distributions for the previous seven days, as required by the U.S. Securities and Exchange Commission.

Average Weighted Maturity. The average length of time until fixed income securities held by a fund reach maturity and are repaid. The figure reflects the proportion of fund assets represented by each security.

Credit Quality. For Vanguard money market funds, the Distribution by Credit Quality table includes tier ratings for consistency with SEC Rule 2a-7 under the Investment Company Act of 1940, which governs money market funds. A First Tier security is one that is eligible for money market funds and has been rated in the highest short-term rating category for debt obligations by the requisite nationally recognized statistical rating organizations. An unrated security is First Tier if it represents quality comparable to that of a rated security, as determined in accordance with SEC Rule 2a-7. A Second Tier security is one that is eligible for money market funds and is not a First Tier security.

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.

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.

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 179 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.

Dear Shareholder,

Aside from a temporary setback in January, U.S. stocks kept climbing during the six months ended February 28, 2014. The environment was generally quite favorable for stocks of midsized and small companies, which outperformed their larger counterparts and the broad U.S. market.

Six-month returns for the Vanguard S&P Mid-Cap 400 Index Funds clustered in a narrow range, from more than 16% for the Value Fund to more than 17% for the Growth Fund. Vanguard S&P Mid-Cap 400 Index Fund, which encompasses both growth and value stocks, was in between with a return of about 17%.

Each fund achieved its objective of closely tracking the performance of its target index, and only the Growth Fund lagged the average return of its peer group.

Mostly positive factors lifted U.S. stock markets
Favorable corporate earnings, generally positive economic news, and the Federal Reserve’s still-accommodative bond-buying program helped the broad U.S. stock market post a strong six-month return of about 16%.

International stocks, in aggregate, returned about 12%. Most of the strength came from the developed markets of Europe; those of the Pacific Rim delivered a

mid-single-digit return. Emerging markets, which have been particularly volatile amid concerns about slower growth in China and the effects of higher interest rates as the Fed winds down its stimulus, also managed a mid-single-digit gain.

Bonds staged a rebound after last year’s swoon
Bond markets posted six-month gains after slumping in 2013 as investors worried over the future of the Fed’s bond-buying program. Even as the Fed began trimming its purchases in January, bonds seemed to regain their appeal. The broad U.S. taxable bond market returned 2.84% for the half year. The yield of the 10-year Treasury note finished the six months at 2.64%, down a bit from 2.76% at the end of August. (Bond prices and yields move in opposite directions.) Money market and savings account returns remained capped by the Fed’s target of 0%–0.25% for short-term interest rates.

Municipal bonds, which had declined sharply in the fiscal year ended August 31, returned 5.71%. The market had been roiled during the summer by headlines about Detroit’s bankruptcy and Puerto Rico’s fiscal woes, but as the headlines receded, investors seemed to take a more comprehensive view of state and local finances. Our chief investment officer, Tim Buckley, noted recently that, on the whole, “municipalities out there are actually doing a lot better than they were a few years ago.”

International bond markets (as measured by the Barclays Global Aggregate Index ex USD, unhedged for currency exposure) returned 4.93%.

Stocks of midsized companies held their lead over larger firms
The February stock market rally after January’s dip helped the S&P 500 Index, a commonly watched indicator of large companies, close at another high. Also hitting a high was the S&P MidCap 400 Index, which represents about 7% of the total value of the U.S. stock market.

In the first half of the new fiscal year, the returns of midsized companies continued to outpace those of large companies, as they had in fiscal-year 2013. Within the S&P family of indexes, the returns of mid-capitalization stocks were in line with those of small-caps—some of the market’s best performers last year. Among both large and midsized companies, growth stocks outperformed their value-oriented counterparts, a reversal of last year’s trend. (Value outpaced growth among small companies.)

Strong performance in three of its largest sectors helped make Vanguard S&P Mid-Cap 400 Growth Index Fund the best performer of the trio with a return of 17.52% for ETF Shares (based on net asset value). Together, consumer discretionary, industrial, and information technology stocks contributed almost 11 percentage points to the fund’s total return. Notwith-

The fund expense ratios shown are from the prospectus dated December 23, 2013, and represent estimated costs for the current fiscal year. For the six months ended February 28, 2014, the funds’ annualized expense ratios were: for the S&P Mid-Cap 400 Index Fund, 0.08% for Institutional Shares and 0.15% for ETF Shares; for the S&P Mid-Cap 400 Value Index Fund, 0.08% for Institutional Shares and 0.20% for ETF Shares; and for the S&P Mid-Cap 400 Growth Index Fund, 0.08% for Institutional Shares and 0.20% for ETF Shares. Peer-group expense ratios are derived from data provided by Lipper, a Thomson Reuters Company, and capture information through year-end 2013.

standing harsh winter weather across much of the United States, consumers opened their wallets. Industrials—notably makers of machinery and equipment—and information technology stocks benefited from continued modest growth in the global economy.

Trends were similar in the Mid-Cap 400 Index Fund, which includes both value and growth stocks and returned 16.91% for ETF Shares. Financials, the largest sector, joined consumer discretionary, industrial, and information technology stocks as the leading contributors to the fund’s return. Real estate investment trusts (REITs), the largest slice of the financial sector, notably boosted results. So, too, did U.S. banks, whose profits continued to grow, aided by the economic recovery and cost cutting.

In the Mid-Cap Value Index Fund, whose ETF Shares returned 16.22%, the financial sector made the largest contribution to total return by virtue of its size—nearly 30% of assets at the end of February. The highest returns, however, were posted by the information technology sector (up more than 25%) and by consumer discretionary and industrials (both up about 19%).

Taking just a slice of the market can add risk to your portfolio
Like other Vanguard funds that are devoted to particular market-capitalization ranges, the Vanguard S&P Mid-Cap 400 Index Funds offer you a low-cost, transparent way to gain exposure to a specific segment of the market. These funds can do important work for an investor—filling in a gap in a portfolio, for example.

A note on expense ratios

The Expense Ratios table in each shareholder 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.

But keep in mind that by choosing just a slice of the market-capitalization pie, you’re also choosing to take on additional risk. Investors who depart from a market-

proportional approach by overweighting a certain segment of the market are exposing themselves to more volatility by reducing their portfolio’s level of diversification.

The appeal of low-cost investing is growing

Minimizing investment costs is a critical part of every investor’s toolkit. Why? Because every dollar paid for fund management expenses is simply a dollar less that can work on your behalf.

Put another way, the lower your mutual fund’s costs, the greater your share of the fund’s return. Not surprisingly, research indicates that lower-cost investments have tended to outperform their higher-cost counterparts.

Investors are catching on to the value of lower-cost mutual funds. Funds with lower expense ratios dominated in attracting investment dollars over the decade ended December 31, 2012, according to a Vanguard research paper. (You can read the paper, Costs Matter: Are Fund Investors Voting With Their Feet?, at vanguard.com/research.) And, as the chart below shows, Vanguard’s leadership in keeping down costs for investors seems to have encouraged the industry to reduce its average costs—at least over the past decade.

Even so, Vanguard’s average expenses continue to be less than one-fifth the industry average: 0.19% versus 1.08% (as of December 31, 2013). That cost difference remains a powerful tool in the hands of Vanguard clients.

Vanguard fund costs remain far below industry average

6

Diversification is, of course, a powerful strategy for managing risk. Vanguard generally counsels that investors have exposure to large-, mid-, and small-cap stocks in a way that approximates the U.S. stock market, because this approach helps ensure that they stay diversified.

As we say in Vanguard’s Principles for Investing Success: “Leadership among market segments changes constantly and rapidly, so investors must diversify both to mitigate losses and to participate in gains.” (Our investment principles are summarized inside the front cover of this report, and you can read more at vanguard.com/research.)

You can achieve a balanced market-cap representation through a total stock market fund, or you can assemble segment-specific funds in a way that mirrors the overall market. Either way, appropriate diversification should remain paramount.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer
March 19, 2014

S&P Mid-Cap 400 Index Fund

Notes to Financial Statements

Vanguard S&P Mid-Cap 400 Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. 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.

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. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract.

Futures contracts are valued at their quoted daily settlement prices. The aggregate notional amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

During the six months ended February 28, 2014, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on quarterly average aggregate settlement values.

22

S&P Mid-Cap 400 Index Fund

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2011–2013), and for the period ended February 28, 2014, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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

B. 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 February 28, 2014, the fund had contributed capital of $82,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.03% 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.

23

S&P Mid-Cap 400 Index Fund

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 February 28, 2014, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	766,053	—	—
Temporary Cash Investments	4,865	300	—
Futures Contracts—Assets1	3	—	—
Total	770,921	300	—
1 Represents variation margin on the last day of the reporting period.

D.At February 28, 2014, 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 Mid-Cap 400 Index	March 2014	17	2,336	69

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 six months ended February 28, 2014, the fund realized $11,367,000 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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $2,595,000 that may be carried forward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

24

S&P Mid-Cap 400 Index Fund

At February 28, 2014, the cost of investment securities for tax purposes was $653,026,000. Net unrealized appreciation of investment securities for tax purposes was $118,192,000, consisting of unrealized gains of $123,305,000 on securities that had risen in value since their purchase and $5,113,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2014, the fund purchased $360,933,000 of investment securities and sold $79,920,000 of investment securities, other than temporary cash investments. Purchases and sales include $116,272,000 and $38,404,000, 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:

	Six Months Ended			Year Ended

S&P Mid-Cap 400 Value Index Fund

Notes to Financial Statements

Vanguard S&P Mid-Cap 400 Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. 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.

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. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract.

Futures contracts are valued at their quoted daily settlement prices. The aggregate notional amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

During the six months ended February 28, 2014, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on quarterly average aggregate settlement values.

38

S&P Mid-Cap 400 Value Index Fund

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2011–2013), and for the period ended February 28, 2014, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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

B. 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 February 28, 2014, the fund had contributed capital of $16,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% 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.

39

S&P Mid-Cap 400 Value Index Fund

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 February 28, 2014, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	148,681	—	—
Temporary Cash Investments	223	100	—
Futures Contracts—Assets1	—	—	—
Total	148,904	100	—
1 Represents variation margin on the last day of the reporting period (the variation margin was less than $1,000).

D. At February 28, 2014, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:

E-mini S&P Mid-Cap 400 Index	March 2014	3	412	4

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 six months ended February 28, 2014, the fund realized $6,078,000 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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $3,060,000 that may be carried forward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

S&P Mid-Cap 400 Value Index Fund

At February 28, 2014, the cost of investment securities for tax purposes was $132,475,000. Net unrealized appreciation of investment securities for tax purposes was $16,529,000, consisting of unrealized gains of $18,153,000 on securities that had risen in value since their purchase and $1,624,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2014, the fund purchased $123,580,000 of investment securities and sold $66,071,000 of investment securities, other than temporary cash investments. Purchases and sales include $46,953,000 and $24,119,000, 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:

At February 28, 2014, one shareholder was the record or beneficial owner of 27% of the fund’s net assets. If the shareholder were to redeem its investment in the fund, the redemption might result in an increase in the fund’s expense ratio, cause the fund to incur higher transaction costs, or lead to the realization of taxable capital gains.

H. Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

S&P Mid-Cap 400 Growth Index Fund

Notes to Financial Statements

Vanguard S&P Mid-Cap 400 Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. 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.

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. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract.

Futures contracts are valued at their quoted daily settlement prices. The aggregate notional amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

During the six months ended February 28, 2014, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on quarterly average aggregate settlement values.

53

S&P Mid-Cap 400 Growth Index Fund

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2011–2013), and for the period ended February 28, 2014, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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

B. 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 February 28, 2014, the fund had contributed capital of $37,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% 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.

54

S&P Mid-Cap 400 Growth Index Fund

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 February 28, 2014, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	348,759	—	—
Temporary Cash Investments	1,042	100	—
Futures Contracts—Assets1	1	—	—
Total	349,802	100	—
1 Represents variation margin on the last day of the reporting period.

D. At February 28, 2014, 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 Mid-Cap 400 Index	March 2014	3	412	13

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 six months ended February 28, 2014, the fund realized $9,797,000 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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $7,588,000 that may be carried forward indefinitely to offset net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

55

S&P Mid-Cap 400 Growth Index Fund

At February 28, 2014, the cost of investment securities for tax purposes was $286,581,000. Net unrealized appreciation of investment securities for tax purposes was $63,320,000, consisting of unrealized gains of $66,631,000 on securities that had risen in value since their purchase and $3,311,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2014, the fund purchased $219,400,000 of investment securities and sold $138,035,000 of investment securities, other than temporary cash investments. Purchases and sales include $88,207,000 and $38,515,000, 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:

	Six Months Ended			Year Ended

	Amount	Shares	Amount	Shares
	($000)	(000)	($000)	(000)

H.Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

About Your Fund’s Expenses

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

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

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

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

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

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

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

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

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

Institutional Shares	$1,000.00	$1,024.40	$0.40
ETF Shares	1,000.00	1,023.80	1.00

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 S&P Mid-Cap 400 Index Fund, 0.08% for Institutional Shares and 0.15% for ETF Shares; for the S&P Mid-Cap 400 Value Index Fund, 0.08% for Institutional Shares and 0.20% for ETF Shares; and for the S&P Mid-Cap 400 Growth Index Fund, 0.08% for Institutional Shares and 0.20% 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.

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.

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.

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 179 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,

Stocks of all capitalization levels joined in the market’s heady rise over the six months ended February 28, 2014. Although large-capitalization stocks didn’t keep up with their mid- and small-cap brethren, they still produced strong results. Vanguard S&P 500 Value Index Fund and Vanguard S&P 500 Growth Index Fund, which invest in U.S. large-capitalization companies, closely tracked their benchmark indexes.

ETF Shares of the Growth Index Fund returned nearly 18%; those of the Value Index Fund returned about 12%. (Returns are based on the ETF Shares’ net asset values.) Vanguard 500 Index Fund, which is a blend of growth and value portfolios, is covered in a separate report. Each fund’s return trailed the average return of its peer funds (the Value Index Fund trailed by about one percentage point and the Growth Index Fund by about two percentage points).

Technology companies were the top contributors to the Growth Index Fund’s return. Financial companies contributed the most to the Value Index Fund’s result, but the fund’s smaller exposure to the technology sector held back returns.

A mostly positive environment lifted U.S. stock market returns
Favorable corporate earnings, generally positive economic news, improved investor sentiment, and the Federal Reserve’s accommodative bond-buying

program all helped the broad U.S. stock market post a six-month return of about 16%.

International stocks, in aggregate, returned about 12%. Most of the strength came from the developed markets of Europe; those of the Pacific region managed single-digit returns. Emerging markets performed similarly but were particularly volatile amid concerns about China’s slowing economy and the effects of higher interest rates as the Fed winds down its stimulus.

Bonds staged a rebound after last year’s swoon
After slumping notably in 2013 as investors worried over the future of the Fed’s stimulus program, bonds delivered solid results for the six months. Even as the tapering began in January, bonds seemed to regain their appeal.

The broad U.S. taxable bond market returned 2.84% for the half-year. The yield of the 10-year Treasury note finished at 2.64%, down a bit from 2.76% at the end of August. (Bond prices and yields move in opposite directions.)

Municipal bonds, which had declined sharply in the fiscal year ended August 31, regained some ground, returning 5.71%. The market was roiled during the summer by news of Detroit’s bankruptcy and Puerto Rico’s fiscal woes, but as the headlines receded, investors seemed to take a more comprehensive view of state and local finances. Our chief investment

officer, Tim Buckley, noted recently that on the whole, “municipalities out there are actually doing a lot better than they were a few years ago.”

Money market and savings account returns remained capped by the Fed’s target of 0%–0.25% for short-term interest rates.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned 4.93%.

A broad-based advance fueled the funds’ returns
Together, the S&P 500 Growth and Value Indexes represent about three-quarters of the U.S. stock market. Large-cap stocks have traditionally generated higher yields, steadier earnings, and less volatility than their smaller-capitalization counterparts. When those characteristics are of utmost importance to equity investors, large-caps are often the market’s leaders.

For the six months, mid- and small-cap stocks outperformed large-caps, with confident investors embracing the risk inherent in holding the shares of smaller firms. At the same time, growth stocks trumped value: Investors were willing to pay more for rapidly expanding companies.

Both funds experienced double-digit sector returns, as the stock market’s broad-based climb encompassed a diverse group of industries. Technology, health care, consumer discretionary, financial, and industrial stocks were among the top contributors to the funds’ returns.

The fund expense ratios shown are from the prospectus dated December 23, 2013, and represent estimated costs for the current fiscal year. For the six months ended February 28, 2014, the annualized expense ratios were: for the S&P 500 Value Index Fund, 0.15%; and for the S&P 500 Growth Index Fund, 0.15%. Peer-group expense ratios are derived from data provided by Lipper, a Thomson Reuters Company, and capture information through year-end 2013.

Because the technology sector was the largest in the Growth Index Fund during the period, its gain of about 20% notably powered the fund’s overall results. Internet companies that command huge audiences

led the way as the movement to online advertising from print continued. Industry consolidation, attractive pricing models, and cloud computing offerings boosted some of the biggest software companies.

The appeal of low-cost investing is growing

Minimizing investment costs is a critical part of every investor’s toolkit. Why? Because every dollar paid for fund management expenses is simply a dollar less that can work on your behalf.

Put another way, the lower your mutual fund’s costs, the greater your share of the fund’s return. Not surprisingly, research indicates that lower-cost investments have tended to outperform their higher-cost counterparts.

Investors are catching on to the value of lower-cost mutual funds. Funds with lower expense ratios dominated in attracting investment dollars over the decade ended December 31, 2012, according to a Vanguard research paper. (You can read the paper, Costs Matter: Are Fund Investors Voting With Their Feet?, at vanguard.com/research.) And, as the chart below shows, Vanguard’s leadership in keeping down costs for investors seems to have encouraged the industry to reduce its average costs—at least over the past decade.

Even so, Vanguard’s average expenses continue to be less than one-fifth the industry average: 0.19% versus 1.08% (as of December 31, 2013). That cost difference remains a powerful tool in the hands of Vanguard clients.

Vanguard fund costs remain far below industry average

Health care stocks were a bright spot for both funds. Pharmaceutical and bio-technology giants dominated various product categories with patents that won’t expire for years. Some benefited from diverse business lines, international expansion, and strategic acquisitions. Improved pipelines for new medicines, along with positive rulings from the Food and Drug Administration, have resulted in a more hospitable business climate. Health care equipment and services firms also excelled.

The Value Index Fund’s largest and most productive sector was financials. Huge banks reduced debt, increased deposits, and generated revenue across multiple business areas. Solid gains also came from diversified financial services giants, insurance firms, asset managers, and consumer finance companies. The strong investing environment, fewer insurance claims, firmer corporate balance sheets, and improved housing and labor markets all boosted this sector.

Within consumer discretionary, a variety of media corporations and retailers reaped rewards from an improving economy and favorable customer trends. The aerospace and defense group stood out in industrials as technological improvements and cost management have helped some companies offset cuts in government spending. Airlines, machinery firms, and conglomerates also contributed significantly to returns.

Taking only a slice of the market can add risk to your portfolio
Like other Vanguard funds that are devoted to particular market capitalization ranges, Vanguard S&P 500 Value Index and Growth Index Funds offer you a low-cost, transparent way to gain exposure to a specific segment of the market. These funds can do important work for an investor—by filling in a gap in a portfolio, for example.

But keep in mind that by choosing just a slice of the larger market pie, you’re also choosing to take on additional risk. Investors who depart from a market-proportional approach by overweighting a segment of the market are exposing themselves to more volatility by reducing their portfolio’s level of diversification.

Diversification is, of course, a powerful strategy for managing risk. Vanguard generally counsels that investors balance exposures to large-, mid-, and small-cap stocks in a way that approximates the U.S. stock market, because this approach helps ensure that they stay diversified.

As we say in Vanguard’s Principles for Investing Success: “Leadership among market segments changes constantly and rapidly, so investors must diversify both to mitigate losses and to participate in gains.” (Read more about our investment principles at vanguard.com/research.)

You can achieve balanced market cap representation through a total-market stock fund or by assembling segment-specific funds to mirror the overall market. Either way, appropriate diversification should be the goal.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

S&P 500 Value Index Fund

Notes to Financial Statements

Vanguard S&P 500 Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. The fund has not issued any Institutional Shares as of February 28, 2014. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker.

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.

2. 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 (August 31, 2011–2013), and for the period ended February 28, 2014, 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. Other: Dividend income is recorded on the ex-dividend date. 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 February 28, 2014, the fund had contributed capital of $15,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% 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).

At February 28, 2014, 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 six months ended February 28, 2014, the fund realized $9,287,000 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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $2,169,000 that may be carried forward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2014, the cost of investment securities for tax purposes was $126,046,000. Net unrealized appreciation of investment securities for tax purposes was $17,053,000, consisting of unrealized gains of $17,979,000 on securities that had risen in value since their purchase and $926,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2014, the fund purchased $80,294,000 of investment securities and sold $68,560,000 of investment securities, other than temporary cash investments. Purchases and sales include $46,950,000 and $34,312,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

F. Capital shares issued and redeemed were:

G.Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

S&P 500 Growth Index Fund

Notes to Financial Statements

Vanguard S&P 500 Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. The fund has not issued any Institutional Shares as of February 28, 2014. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker.

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.

2. 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 (August 31, 2011–2013), and for the period ended February 28, 2014, 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. Other: Dividend income is recorded on the ex-dividend date. 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 February 28, 2014, the fund had contributed capital of $23,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% 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).

At February 28, 2014, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

30

S&P 500 Growth Index Fund

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 six months ended February 28, 2014, the fund realized $6,554,000 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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $3,547,000 that may be carried forward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2014, the cost of investment securities for tax purposes was $178,256,000. Net unrealized appreciation of investment securities for tax purposes was $42,893,000, consisting of unrealized gains of $43,538,000 on securities that had risen in value since their purchase and $645,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2014, the fund purchased $130,581,000 of investment securities and sold $83,582,000 of investment securities, other than temporary cash investments. Purchases and sales include $84,297,000 and $32,876,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

F. Capital shares issued and redeemed were:

	Six Months Ended	Year Ended
	February 28, 2014	August 31, 2013
	Shares	Shares
	(000)	(000)
ETF Shares
Issued	1,000	800
Issued in Lieu of Cash Distributions	—	—
Redeemed	(450)	(300)
Net Increase (Decrease) in Shares Outstanding	550	500

G. Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

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.

S&P 500 Growth Index Fund
ETF Shares	$1,000.00	$1,024.05	$0.75

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 S&P 500 Value Index Fund, 0.15%; and for the S&P 500 Growth Index Fund, 0.15%. 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 peiod, 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.

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.

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.

34

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.

35

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 179 Vanguard funds.

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

Chairman’s Letter

Dear Shareholder,

The stock market’s rally since its bottom five years ago has delivered generous returns for stock investors across the board. And while the rising tide has seemingly lifted all boats, the upswing has favored small-capitalization stocks over large-cap stocks.

The S&P SmallCap 600 Index notched an average annual return of about 32% from the stock market bottom on March 9, 2009, to February 28, 2014, compared with about 25% for the large-cap S&P 500 Index. During the latest reporting period, small-cap stocks continued to outpace large-caps. For the six months ended February 28, 2014, the S&P SmallCap 600 Index returned about 17%, and the S&P 500 Index returned about 15%.

During the six-month period, ETF Shares of Vanguard S&P Small-Cap 600 Index Fund returned 17.02%. (Institutional Shares returned 17.09%.) For the three funds in this report, value stocks outperformed growth stocks: Vanguard S&P Small-Cap 600 Value Index Fund returned 17.51% and Vanguard S&P Small-Cap 600 Growth Index Fund returned 16.50%. (Returns are for ETF Shares, based on net asset value.) The funds’ results were in line with their benchmark indexes. The returns for the broader fund and the value fund were higher than the average returns of their peers; the growth fund’s return was not.

Mostly positive factors lifted U.S. stock markets
Favorable corporate earnings, generally positive economic news, improved investor sentiment, and the Federal Reserve’s accommodative bond-buying program—all of these factors underpinned the broad U.S. stock market’s six-month return of about 16%.

International stocks, in aggregate, returned about 12%. Most of the strength came from the developed markets of Europe. The developed markets of the Pacific region managed single-digit returns for the period, as did emerging markets, which have seen particularly volatile results amid concerns about China’s slowing economy and the effects of higher interest rates as the Fed winds down its stimulus.

Bonds staged a rebound after last year’s swoon
Bonds, which had slumped notably in 2013 as investors worried over the future of the Fed’s bond-buying program, delivered solid results for the six months. Even as the Fed began trimming its purchases in January, bonds seemed to regain their appeal for investors.

The broad U.S. taxable bond market returned 2.84% for the half year. The yield of the 10-year Treasury note finished the six months at 2.64%, down a bit from 2.76% at the end of August. (Bond prices and yields move in opposite directions.)

Municipal bonds, which had declined sharply in the fiscal year ended August 31, regained some ground, returning 5.71%.

The market had been roiled during the summer by headlines about Detroit’s bankruptcy and Puerto Rico’s fiscal woes, but as the headlines receded, investors seemed to take a more comprehensive view of state and local finances. Our chief investment officer, Tim Buckley, noted recently that, on the whole, “municipalities out there are actually doing a lot better than they were a few years ago.”

Money market and savings account returns remained capped by the Fed’s target of 0%–0.25% for short-term interest rates. International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned 4.93%.

Technology was a top contributor to returns for each fund
The potential of small companies to deliver outsized increases in sales and profit seemed to attract investors to their stocks during the fiscal period. The prospect for robust growth may be particularly appealing at a time when the larger economy has expanded at only a tepid pace. Of course, the potential opportunity presented by small companies also comes with a risk; companies of this size are more likely than large-cap companies to experience earnings volatility, and they are more sensitive to the ebbs and flows of the economic cycle.

S&P Small-Cap 600 Index Fund	0.11%	0.18%	1.32%
S&P Small-Cap 600 Value Index Fund	—	0.23	1.36
S&P Small-Cap 600 Growth Index Fund	—	0.23	1.42

The fund expense ratios shown are from the prospectus dated December 23, 2013, and represent estimated costs for the current fiscal year. For the six months ended February 28, 2014, the annualized expense ratios were: for the S&P Small-Cap 600 Index Fund, 0.08% for Institutional Shares and 0.15% for ETF Shares; for the S&P Small-Cap 600 Value Index Fund, 0.20% for ETF Shares; and for the S&P Small-Cap 600 Growth Index Fund, 0.20% for ETF Shares. Peer-group expense ratios are derived from data provided by Lipper, a Thomson Reuters Company, and capture information through year-end 2013.

Peer groups: For the S&P Small-Cap 600 Index Fund, Small-Cap Core Funds; for the S&P Small-Cap 600 Value Index Fund, Small-Cap Value Funds; and for the S&P Small-Cap 600 Growth Index Fund, Small-Cap Growth Funds.

Five industry sectors were responsible for the bulk of the returns for the three Vanguard S&P Small-Cap 600 Index Funds for the six months: information technology, health care, consumer discretionary, financials, and industrials.

Technology was a top contributor for each fund on the strength of a wide variety of industries within that sector. For the value fund, industrial stocks were the leading contributor, helped especially by the performance of aerospace and defense companies and machinery manufacturers.

In health care, a core contributor for each fund was the subsector that includes businesses that provide equipment and

services. Among consumer discretionary stocks, each fund benefited from its holdings of consumer durables and apparel stocks (such as those of companies that provide apparel accessories and luxury goods) as well as consumer services stocks (such as restaurants). The value fund also got a boost from retailing.

For each fund, regional bank and real estate stocks were important contributors to results in the financial sector.

Taking only a slice of the market can add risk to your portfolio
Like other Vanguard funds that are devoted to particular market-capitalization ranges, the Vanguard S&P Small-Cap 600 Index

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.

Funds offer you a low-cost, transparent way to gain exposure to a specific segment of the market. These funds can do important work for an investor—filling in a gap in a portfolio, for example.

But keep in mind that by choosing just a slice of the market-cap pie, you’re also choosing to take on additional risk. Investors who depart from a market-proportional approach by overweighting a certain

The appeal of low-cost investing is growing

Minimizing investment costs is a critical part of every investor’s toolkit. Why? Because every dollar paid for fund management expenses is simply a dollar less that can work on your behalf.

Put another way, the lower your mutual fund’s costs, the greater your share of the fund’s return. Not surprisingly, research indicates that lower-cost investments have tended to outperform their higher-cost counterparts.

Investors are catching on to the value of lower-cost mutual funds. Funds with lower expense ratios dominated in attracting investment dollars over the decade ended December 31, 2012, according to a Vanguard research paper. (You can read the paper, Costs Matter: Are Fund Investors Voting With Their Feet? at vanguard.com/research.) And, as the chart below shows, Vanguard’s leadership in keeping down costs for investors seems to have encouraged the industry to reduce its average costs—at least over the past decade.

Even so, Vanguard’s average expenses continue to be less than one-fifth the industry average: 0.19% versus 1.08% (as of December 31, 2013). That cost difference remains a powerful tool in the hands of Vanguard clients.

Vanguard fund costs remain far below industry average

segment of the market are exposing themselves to more volatility by reducing their portfolio’s level of diversification.

Diversification is, of course, a powerful strategy for managing risk, and Vanguard generally counsels that investors get exposure to large-, mid-, and small-cap stocks in a way that approximates the U.S. stock market, because this approach helps ensure that they stay diversified.

As we say in Vanguard’s Principles for Investing Success: “Leadership among market segments changes constantly and rapidly, so investors must diversify both to mitigate losses and to participate in gains.” (You can read more about our investment principles at vanguard.com/research.)

You can achieve a balanced market-cap representation through a total-market stock fund, or you can assemble segment-specific funds to mirror the overall market. Either way, appropriate diversification should remain paramount.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

S&P Small-Cap 600 Index Fund

Notes to Financial Statements

Vanguard S&P Small-Cap 600 Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. 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.

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. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract.

Futures contracts are valued at their quoted daily settlement prices. The aggregate notional amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

During the six months ended February 28, 2014, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, 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 (August 31, 2011–2013), and for the period ended February 28, 2014, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

6. Other: Dividend income is recorded on the ex-dividend date. Interest is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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

B. 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 February 28, 2014, the fund had contributed capital of $34,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% 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 February 28, 2014, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	322,836	—	—
Temporary Cash Investments	31	100	—
Futures Contracts—Liabilities1	(2)	—	—
Total	322,865	100	—
1 Represents variation margin on the last day of the reporting period.

D. At February 28, 2014, 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 2014	4	473	4

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 six months ended February 28, 2014, the fund realized $17,027,000 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.

26

S&P Small-Cap 600 Index Fund

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $1,022,000 that may be carried forward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2014, the cost of investment securities for tax purposes was $256,713,000.

Net unrealized appreciation of investment securities for tax purposes was $66,254,000, consisting of unrealized gains of $69,942,000 on securities that had risen in value since their purchase and $3,688,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2014, the fund purchased $118,519,000 of investment securities and sold $71,531,000 of investment securities, other than temporary cash investments. Purchases and sales include $91,906,000 and $48,255,000, 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:

	Six Months Ended			Year Ended
	February 28, 2014		August 31, 2013
	Amount	Shares	Amount	Shares
	($000)	(000)	($000)	(000)
Institutional Shares
Issued	19,096	102	50,427	318
Issued in Lieu of Cash Distributions	1,594	8	1,594	11
Redeemed	(16,148)	(86)	(28,624)	(177)
Net Increase (Decrease)—Institutional Shares	4,542	24	23,397	152
ETF Shares

Redeemed	(48,093)	(500)	(3,492)	(50)
Net Increase (Decrease)—ETF Shares	42,616	450	38,265	500

At February 28, 2014, one shareholder was the record or beneficial owner of 38% of the fund’s net assets. If the shareholder were to redeem its investment in the fund, the redemption might result in an increase in the fund’s expense ratio, cause the fund to incur higher transaction costs, or lead to the realization of taxable capital gains.

H. Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

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

S&P Small-Cap 600 Value Index Fund

Notes to Financial Statements

Vanguard S&P Small-Cap 600 Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. During the six months ended February 28, 2014, there were no investors in the Institutional share class. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker.

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.

2. 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 (August 31, 2011–2013), and for the period ended February 28, 2014, 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. Other: Dividend income is recorded on the ex-dividend date. Interest income 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 February 28, 2014, the fund had contributed capital of $6,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.00% 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).

At February 28, 2014, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

S&P Small-Cap 600 Value Index Fund

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 six months ended February 28, 2014, the fund realized $4,434,000 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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $920,000 that may be carried forward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2014, the cost of investment securities for tax purposes was $47,221,000.

Net unrealized appreciation of investment securities for tax purposes was $5,785,000, consisting of unrealized gains of $6,555,000 on securities that had risen in value since their purchase and $770,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2014, the fund purchased $51,399,000 of investment securities and sold $33,421,000 of investment securities, other than temporary cash investments. Purchases and sales include $36,685,000 and $18,522,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

F. Capital shares issued and redeemed were:

	Six Months Ended	Year Ended
	February 28, 2014	August 31, 2013
	Shares	Shares
	(000)	(000)
Issued	400	200
Issued in Lieu of Cash Distributions	—	—
Redeemed	(200)	(100)
Net Increase (Decrease) in Shares Outstanding	200	100

G.Management has determined that no material events or transactions occurred subsequent to February 28, 2014, that would require recognition or disclosure in these financial statements.

Performance Summary

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

S&P Small-Cap 600 Growth Index Fund

Notes to Financial Statements

Vanguard S&P Small-Cap 600 Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Institutional Shares and ETF Shares. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. Institutional Shares were issued and redeemed during the reporting period. As of February 28, 2014, there were no investors in the Institutional share class. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker.

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.

2. 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 (August 31, 2011–2013), and for the period ended February 28, 2014, 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. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

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 February 28, 2014, the fund had contributed capital of $6,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.00% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

S&P Small-Cap 600 Growth Index Fund

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).

At February 28, 2014, 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 six months ended February 28, 2014, the fund realized $5,247,000 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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2013, the fund had available capital losses totaling $910,000 that may be carryforward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2014; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2014, the cost of investment securities for tax purposes was $57,791,000.

Net unrealized appreciation of investment securities for tax purposes was $3,277,000, consisting of unrealized gains of $4,650,000 on securities that had risen in value since their purchase and $1,373,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2014, the fund purchased $71,964,000 of investment securities and sold $37,807,000 of investment securities, other than temporary cash investments. Purchases and sales include $55,025,000 and $20,408,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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.

S&P Small-Cap 600 Growth Index Fund
ETF Shares	$1,000.00	$1,023.80	$1.00

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 S&P Small-Cap 600 Index Fund, 0.08% for Institutional Shares and 0.15% for ETF Shares; for the S&P Small-Cap 600 Value Index Fund, 0.20% for ETF Shares; and for the S&P Small-Cap 600 Growth Index Fund, 0.20% 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.

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.

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.

56

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 179 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.
