The mission continues

On May 1, 1975, Vanguard began operations, a fledgling company based on the simple but revolutionary idea that a mutual fund company should be managed solely in the interest of its investors.

Four decades later, that revolutionary spirit continues to animate the enterprise. Vanguard remains on a mission to give investors the best chance of investment success.

As we mark our 40th anniversary, we thank you for entrusting your assets to Vanguard and giving us the opportunity to help you reach your financial goals in the decades to come.

Chairman’s Letter

Dear Shareholder,

Since late 2008, the Federal Reserve’s target for short-term interest rates has remained between 0% and 0.25%, a historically low figure that has resulted in minuscule returns for money market funds and savings accounts. The six months ended February 28, 2015, were no exception.

Vanguard Prime Money Market Fund returned 0.00% for Investor Shares and 0.03% for Institutional Shares, which have a lower expense ratio. Vanguard Federal Money Market Fund and Vanguard Admiral Treasury Money Market Fund also each returned 0.00%.

The funds’ 7-day SEC yields were about what they were six months ago. As of February 28, yields for the Admiral Treasury Money Market Fund, Federal Money Market Fund, and Investor Shares of the Prime Money Market Fund were unchanged at 0.01%. The yield for the Prime Money Market Fund’s Institutional Shares increased to 0.07% from 0.05%.

Bonds notched positive results despite early and late retreats

The broad U.S. taxable bond market returned 2.25%, although bond prices declined over the period’s first and final months. When the stock market turned volatile, investors favored the relative safety offered by bonds, which also benefited from various global stimulus programs.

Conversely, bond prices fell in February as the Fed suggested that a midyear interest rate increase was an option if the economy continued to perform well. The yield of the 10-year Treasury note ended February at 2.03%, down from 2.34% six months earlier. (Bond prices and yields move in opposite directions.)

Municipal bonds, which returned 2.21%, lost some steam toward the end of the period amid increased bond issuance and the prospect of higher interest rates.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –9.54%, weighed down by the weakness of foreign currencies relative to the dollar. International bonds hedged to eliminate the effect of currency exchange rates produced positive returns.

A surge in February powered U.S. stocks for the period

U.S. stocks performed solidly but unevenly over the six months. Despite declines in two of those months and flat returns in another, the broad U.S. stock market ended the period up about 6%.

The overall return was powered by a robust advance in February, when the broad market recorded its largest monthly gain since October 2011. Investors were cheered by stabilization in oil prices and guidance from the Federal Reserve that it wouldn’t raise interest rates prematurely.

International stocks returned about –3% in dollar terms. The dollar’s strength against many foreign currencies, along with various geopolitical issues, restrained results. Stocks in emerging markets and the developed markets of the Pacific region and Europe backtracked, with emerging markets faring the worst. In local currency terms, though, international stocks rose.

Safety and liquidity remain top priorities for the funds

Although any interest rate changes hinge on the economy’s progress, the Federal Reserve has indicated that it may begin raising short-term interest rates later this year. Chairwoman Janet Yellen and other Fed officials have discussed the improve-ments in the economy and labor market, and the Fed ended its stimulative bond-buying program in October.

The funds’ negligible returns have no doubt discouraged investors, many of whom have traditionally counted on such investments for a degree of income. Of course, providing income is one of the portfolio’s objectives, but it comes third in line behind providing safety and liquidity. To that end, Vanguard’s Fixed Income Group manages the funds conservatively and invests primarily in money market securities that are rated in the two highest credit-quality categories (as determined by nationally recognized credit-rating services).

The fund expense ratios shown are from the prospectus dated December 19, 2014, and represent estimated costs for the current fiscal year.
For the six months ended February 28, 2015, 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, 0.09%; for the Admiral Treasury Money Market Fund, 0.03%.
The 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 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%.

U.S. government securities are the focus of the Admiral Treasury Money Market Fund and Federal Money Market Fund and also represent a significant portion of the Prime Money Market Fund. Treasury securities are backed by the full faith and credit of the United States and are widely embraced whenever economic and market conditions rattle investors. The Federal Money Market Fund holds federal agency securities, which maintain nearly the same credit quality as securities issued by the U.S. government.

About a year ago, the Treasury launched a two-year floating-rate note, which the Fixed Income Group originally included in the Admiral Treasury Money Market Fund. With the notes available at bargain prices over the recent period, the advisor bought them for all three funds, with the objective of adding value to the portfolio.

Yankee/foreign issues are the Prime Money Market’s Fund largest single investment. These securities, denominated in U.S. dollars to eliminate currency risk, are from highly rated foreign issuers and do not include financial paper from economically troubled countries in southern Europe.

As we noted in last year’s annual report, the Securities and Exchange Commission has adopted a number of changes to money market regulations.

In response to the new rules, which in the future may allow a fund to impose liquidity fees and redemption limits if weekly liquid

assets fall below 30%, the Fixed Income Group increased the Prime Money Market’s minimum percentage of weekly liquid assets to 40% to provide an additional buffer.

The vast majority of investors in Vanguard money market funds will not be affected by the changes. Although some rules must be implemented sooner, the compliance date for the core reforms is in autumn 2016, which gives investors time to find alternatives if they wish. We will report to you again as we work through the implications of these changes for our clients and our lineup of funds.

To build for the long term, start with a solid foundation

As the leader of a major investment firm, I get asked a lot of questions on all kinds of topics, from the outlook for global markets to the best fund choices for an IRA. But a topic that almost never comes up—and one that I consider perhaps the most important—is setting investment goals.

At Vanguard, we believe that following four timeless, straightforward principles can help put you on the right track toward investment success:

• Goals. Create clear, appropriate
investment goals.

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

• Cost. Minimize cost.

• Discipline. Maintain perspective and
long-term discipline.

All four are essential, and the order in which they’re listed is intentional. Every good investment plan begins with a clearly defined goal, which sets the foundation for building your portfolio. (You can read more in Vanguard’s Principles for Investing Success, available at vanguard.com/research.)

Setting an investment goal doesn’t have to be complicated. A goal can be as simple as saving for retirement or for a child’s college education. Being realistic about your goals—and how to meet them—can help you stick with your investment plan even when times get tough.

In many parts of the United States, it’s been an especially bitter and challenging winter, but spring is now upon us. The change of seasons can be an occasion for some financial spring cleaning. Consider taking time now to revisit your investment plan, ensuring that your objectives are clear, and making any necessary adjustments to help you reach your long-term financial goals.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Advisor’s Report

The extremely low interest rate environment that has prevailed since the financial crisis has made it very difficult for money market funds to deliver much in the way of income. Our funds have nevertheless continued to offer investors a conservative, high-quality, very liquid investment for their short-term savings goals or cash management needs.

For the six months ended February 28, 2015, Investor Shares of Vanguard Prime Money Market Fund returned 0.00%, while Institutional Shares, with their lower expense ratio, returned 0.03%. Vanguard Federal Money Market Fund and Vanguard Admiral Treasury Money Market Fund both returned 0.00%. The average return for the peer groups of all three funds was 0.00%.

The investment environment

Over the six months, the United States remained on a different trajectory than much of the world. The Eurozone and Japan continued to grapple with anemic growth and deflationary pressures, and China saw its pace of economic expansion shift down a gear. Their central banks responded with interest rate cuts and quantitative easing aimed at reversing those trends.

In contrast, the U.S. economy continued expanding at a good clip. The United States saw sustained growth in the labor market along with an upturn in consumer confidence. The improvements paved the way for the Federal Reserve to bring its stimulative bond-buying program to a close at the end of October.

Longer-term yields nevertheless continued to move lower. Risk-averse investors, seeking a safe harbor from volatility driven by geopolitical tensions, stepped in and helped counter slackening demand from the Fed. International investors also were increasingly attracted to U.S. bonds, given their comparatively high yields and the strong dollar.

Although forward guidance from the Fed about an eventual increase in interest rates helped yields of short-term bonds move a little higher over the six months, yields of money market instruments remained at rock-bottom levels.

Management of the funds

Over the six months, we expanded our use of a relatively new offering from the U.S. Treasury Department—the 2-year floating-rate note. We began putting these notes, which trade at a spread to 3-month Treasury bills, in the Admiral Treasury Fund last year with an eye to adding some diversification to its holdings. As the pricing of these notes became more attractive, we included them in the Federal and Prime Money Market Funds as well.

In the Prime Money Market Fund, debt issued by Canadian and Australian banks remained an important avenue of diversification in our regional exposure to banks. Our ongoing credit analysis brought Japanese banks back onto our radar screen for the first time in decades because of the improvements we’ve seen in their fundamentals. On the other hand, we remained very selective regarding

European banks because of the challenges and uncertainty in the region. At the end of the period, our exposure here was limited to the debt of banks in the United Kingdom and a handful of northern European countries.

Regarding corporate debt in the Prime Money Market Fund, we increased our exposure to commercial paper of some large, high-quality oil and gas companies. Plunging oil prices prompted energy companies to issue short-term debt, as they occasionally do, giving us an opportunity to further diversify the portfolio.

We are continuing to review the changes announced last year by the Securities and Exchange Commission to regulations governing money market funds. Although many of the changes do not take effect until October 2016, our funds already meet or exceed some of the new criteria. In the Prime Money Market Fund, for example, weekly liquidity is running at about 40% of assets, notably higher than the 30% level below which liquidity fees or redemption gates could be applied in the future.

And more than 99.5% of the assets of the Admiral Treasury and Federal Money Market Funds are invested in cash, government securities, or repurchase agreements collateralized by government securities and cash, so they already meet the SEC’s new definition of a government money market fund. (The requirement previously was 80%.)

The outlook

We expect the U.S. economy to remain resilient amid the global slowdown and to continue its moderate expansion. Even though the slump in oil prices has dampened inflation, the Federal Reserve seems likely to look past the recent weakness in prices and raise the federal funds rate later this year from the emergency level it’s been at since 2008.

Although a rate increase will be a welcome development for savers and our money market funds, the pace of monetary tightening is likely to be slow, and the target rate may end up below its historical average. A rise in rates will probably bring greater market volatility as well.

As we enter the second half of the fiscal year, the average maturities of the funds are a little shorter than they were six months ago. That should give us the flexibility to invest in higher-yielding longer-term maturities if good opportunities arise.

As always, whatever the markets may bring, our experienced team of portfolio managers, traders, and credit analysts will continue to seek out opportunities to produce competitive returns.

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 nationally recognized statistical rating organizations. Credit-quality ratings are obtained from Moody's,
Fitch, and S&P. For securities rated by all three agencies, where two of them are in agreement and assign the highest rating
category, the highest rating applies. If a security is only rated by two agencies, and their ratings are in different categories, the
lower of the ratings applies. 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. For more information about these ratings, see the Glossary entry for Credit Quality.

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.

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. investment companies. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. 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.

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, 2011–2014), and for the period ended February 28, 2015, 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. Credit Facility: The fund and certain other funds managed by The Vanguard Group participate in a $2.89 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.06% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board

Prime Money Market Fund

of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

6. 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 based on methods approved by the board of trustees. The fund has committed to invest up to 0.40% of its net assets in Vanguard. At February 28, 2015, the fund had contributed capital of $12,395,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 4.96% 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, 2015, Vanguard’s expenses were reduced by $8,126,000 (an effective annual rate of 0.02% 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).

At February 28, 2015, 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.

Federal Money Market Fund

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.

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 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.

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

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

Federal Money Market Fund

6. 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 based on methods approved by the board of trustees. The fund has committed to invest up to 0.40% of its net assets in Vanguard. At February 28, 2015, the fund had contributed capital of $275,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.11% 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, 2015, Vanguard’s expenses were reduced by $298,000 (an effective annual rate of 0.02% of the fund’s average net assets).

D. Management has determined that no material events or transactions occurred subsequent to February 28, 2015, that would require recognition or disclosure in these financial statements.

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.

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, 2011–2014), and for the period ended February 28, 2015, 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. Credit Facility: The fund and certain other funds managed by The Vanguard Group participate in a $2.89 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.06% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

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.

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, 2015, Vanguard’s expenses were reduced by $2,909,000 (an effective annual rate of 0.06% of the fund’s average net assets).

D. Management has determined that no material events or transactions occurred subsequent to February 28, 2015, 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.

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, 0.09%; and for the Admiral Treasury Money Market Fund, 0.03%. 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 nationally recognized statistical rating organizations. Credit-quality ratings are obtained from Moody’s, Fitch, and S&P. For securities rated by all three agencies, where two of them are in agreement and assign the highest rating category, the highest rating applies. If a security is only rated by two agencies, and their ratings are in different categories, the lower of the ratings applies. 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.

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 178 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,

Growth stocks were at the forefront of the market’s advance over the six months ended February 28, 2015, as investors seemed encouraged by the domestic economy’s gathering momentum.

In this environment, returns for the Vanguard S&P Mid-Cap 400 Index Funds ranged from about 7% for the Growth Index Fund to nearly 4% for the Value Index Fund. Vanguard S&P Mid-Cap 400 Index Fund, which encompasses both growth and value stocks, fell in between with a return of more than 5%.

Each fund met its objective of closely tracking its target index; each fund also surpassed the average return of its peers.

As we announced earlier, the S&P Mid-Cap 400 Index Fund and 23 other funds in Vanguard’s lineup will begin paying a dividend each quarter rather than once a year. The change, which will take effect in the third quarter of 2015, should align distributions more closely with shareholders’ need for income and help the funds operate more efficiently.

A surge in February powered U.S. stocks for the period

U.S. stocks performed solidly but unevenly over the six months. Despite declines in two of those months and flat returns in another, the broad U.S. stock market ended the period up about 6%.

Overall returns were powered by a robust advance in February, when the broad market recorded its largest monthly gain since October 2011. Investors were cheered by stabilization in oil prices and guidance from the Federal Reserve that it wouldn’t raise interest rates prematurely.

After some ups and downs, international stocks returned about –3% in dollar terms. The dollar’s strength against many foreign currencies, along with various geopolitical issues, restrained results. Stocks in emerging markets and the developed markets of the Pacific region and Europe backtracked, with emerging markets faring the worst. In local currency terms, though, international stocks rose.

Bonds notched positive results despite early and late retreats

Russell 1000 Index (Large-caps)	6.00%	14.88%	16.39%
Russell 2000 Index (Small-caps)	5.70	5.63	15.97
Russell 3000 Index (Broad U.S. market)	5.98	14.12	16.36

Citigroup Three-Month U.S. Treasury Bill Index	0.00	0.03	0.06

CPI
Consumer Price Index	-1.32%	-0.03%	1.61%

Municipal bonds, which returned 2.21%, lost some steam toward the end of the period amid increased bond issuance and the prospect of higher interest rates.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –9.54%, weighed down by the weakness of foreign currencies relative to the dollar. On a currency-hedged basis, international bonds advanced.

Money market funds and savings accounts provided scant returns as the Fed’s target for short-term rates remained at 0%–0.25%.

Mid-capitalization stocks posted mostly solid results

As I mentioned earlier in this letter, growth stocks held the advantage over value for the half year. Experienced investors know that the various categories of equity investments take turns leading the market. One period it might be large-cap growth at the forefront, and the next it might be small-cap value. These unpredictable shifts in market leadership are one of the reasons why Vanguard believes broad diversification is the wisest choice for most investors. Mid-cap stocks can be a component of a well-balanced, long-term portfolio, and the Vanguard S&P Mid-Cap


Expense Ratios
Your Fund Compared With Its Peer Group

	Institutional	ETF	Peer Group

S&P Mid-Cap 400 Index Fund	0.08%	0.15%	1.19%
S&P Mid-Cap 400 Value Index Fund	0.08	0.20	1.29
S&P Mid-Cap 400 Growth Index Fund	0.08	0.20	1.31

The fund expense ratios shown are from the prospectus dated December 19, 2014, and represent estimated costs for the current fiscal year.
For the six months ended February 28, 2015, 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 0.19% 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 2014.

Peer groups: For the S&P Mid-Cap 400 Index Fund, Mid-Cap Core Funds; for the S&P Mid-Cap 400 Value Index Fund, Mid-Cap Value Funds;
and for the S&P Mid-Cap 400 Growth Index Fund, Mid-Cap Growth Funds.

400 Index Funds offer a convenient and low-cost way to gain exposure to that part of the market.

Mid-caps straddle the worlds of large-and small-caps; the group is known for its potential to grow earnings faster than large-caps but with less volatility than small-caps. That may sound as if investing in mid-caps would get you the “best of both worlds,” but make no mistake: Mid-caps, like all stocks, are subject to risks that are best managed by diversifying.

Over the half year, the financial sector’s strength was a key to the Vanguard S&P Mid-Cap 400 Index Funds’ solid showing. The sector ended the period as one of the largest for all three funds and was the leading contributor to the Mid-Cap 400 Index and Value Index Funds. A healthy investment climate and the growing economy boosted asset managers, brokerage firms, real estate investment trusts (REITs), insurance firms, diversified financial services companies, and banks.

All three funds also benefited significantly from health care stocks, which were the top contributor for the Growth Index Fund. The industry generally profited as investors anticipated a rise in spending given the aging population and the expanded number of insured under the Affordable Care Act, despite lingering concerns about regulation’s effects on the managed-care industry. Health care providers, especially managed-care companies, flourished. Innovative products and therapies helped medical equipment firms.

Another sector whose results boosted all three funds was information technology. Strong returns for software, semiconductor, and internet companies offset weakness among hardware and electronic equipment firms. Smartphones, other mobile technologies, and cloud computing are evolving and expanding in the United States and overseas, and inventive, well-managed companies that supply and support these industries excelled.

Consumer staples and consumer discretionary stocks also did well as the economy and labor market continued to improve. Both sectors gained from a plunge in oil prices, which freed up money consumers had previously earmarked for the gas pump. Results for the industrial, materials, telecommunication services, and utilities sectors varied somewhat among the three funds; however, these results had a minimal impact on the funds’ overall returns.

Although the oil-price changes helped some segments of the economy, the declines severely buffeted the energy sector. With their profits cut, producers scaled back on projects that are the lifeblood of service firms, drillers, and equipment providers. Companies that refine crude oil into other products held up better, benefiting from lower prices for their primary raw material.

Both ETFs and mutual funds offer the chance for long-term success

The popularity of exchange-traded funds (ETFs), most of which seek to track an index, has surged over the past decade. We see this as an indication that our message is taking hold: Broad diversification and low costs are keys to long-term success, and indexing is a great way to implement strategies based on those tenets.

As you probably know, ETFs combine the investment characteristics of mutual funds with the trading characteristics of stocks. As with stocks, ETF prices change throughout the day. In contrast, traditional open-end mutual funds are priced once a day, shortly after the market’s close.

Some say ETFs are more of a trading tool than an investment tool. We don’t think this has to be the case. In fact, we’re seeing much greater use of ETFs as part of long-term plans. Certainly, they are easy to trade. But they are also easy to hold. And, unlike with traditional mutual funds, the investor doing the trading is the one who pays the transaction costs—not the other fund shareholders.

Vanguard ETFs^®are simply another share class of our traditional mutual funds. Clients select the share class that best meets their needs. The portfolios are identical. Vanguard research has shown that ETFs and mutual funds perform essentially the same investment function,

and that investors can use both to create a low-cost, well-diversified portfolio of stocks and bonds. You can read more in Buying on the FACTS: Investors’ Choices Between ETFs and Mutual Funds, available at vanguard.com/research.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

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.

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

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract.

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

During the six months ended February 28, 2015, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on the average of aggregate settlement values at each quarter-end during the period.

S&P Mid-Cap 400 Index Fund

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 counter-party risk by entering into securities lending transactions only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master securities lending agreements with its counterparties. The master securities lending agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan.

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group participate in a $2.89 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.06% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

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

S&P Mid-Cap 400 Index Fund

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.

The following table summarizes the market value of the fund’s investments as of February 28, 2015, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P Mid-Cap 400 Index	March 2015	15	2,257	54

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

S&P Mid-Cap 400 Index Fund

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, 2015, the fund realized $29,626,000 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, 2014, the fund had available capital losses totaling $2,274,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $790,482,000.

Net unrealized appreciation of investment securities for tax purposes was $156,500,000, consisting of unrealized gains of $182,685,000 on securities that had risen in value since their purchase and $26,185,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $183,507,000 of investment securities and sold $145,406,000 of investment securities, other than temporary cash investments. Purchases and sales include $91,150,000 and $91,761,000, 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:

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.

S&P Mid-Cap 400 Value Index Fund

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 in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

The following table summarizes the market value of the fund’s investments as of February 28, 2015, based on the inputs used to value them:


	Level 1	Level 2	Level 3

Total	264,181	100	—
1 Represents variation margin on the last day of the reporting period.

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P Mid-Cap 400 Index	March 2015	3	451	16

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

S&P Mid-Cap 400 Value Index Fund

During the six months ended February 28, 2015, the fund realized $16,553,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

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, 2014, the fund had available capital losses totaling $2,736,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $250,170,000. Net unrealized appreciation of investment securities for tax purposes was $14,113,000, consisting of unrealized gains of $21,564,000 on securities that had risen in value since their purchase and $7,451,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $194,417,000 of investment securities and sold $164,058,000 of investment securities, other than temporary cash investments. Purchases and sales include $89,397,000 and $77,779,000, 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:

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.

S&P Mid-Cap 400 Growth Index Fund

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 in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P Mid-Cap 400 Index	March 2015	5	752	31

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.

S&P Mid-Cap 400 Growth Index Fund

During the six months ended February 28, 2015, the fund realized $23,274,000 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, 2014, the fund had available capital losses totaling $7,331,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $369,706,000. Net unrealized appreciation of investment securities for tax purposes was $77,961,000, consisting of unrealized gains of $81,204,000 on securities that had risen in value since their purchase and $3,243,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $270,210,000 of investment securities and sold $230,720,000 of investment securities, other than temporary cash investments. Purchases and sales include $112,268,000 and $84,137,000, 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, 2015		August 31, 2014
	Amount	Shares	Amount	Shares
	($000)	(000)	($000)	(000)

H. Management has determined that no material events or transactions occurred subsequent to February 28, 2015, that would require recognition or disclosure in these financial statements.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2015
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	8/31/2014	2/28/2015	Period
Based on Actual Fund Return
S&P Mid-Cap 400 Index Fund
Institutional Shares	$1,000.00	$1,054.95	$0.41
ETF Shares	1,000.00	1,054.54	0.76
S&P Mid-Cap 400 Value Index Fund
Institutional Shares	$1,000.00	$1,038.30	$0.40
ETF Shares	1,000.00	1,037.68	0.96
S&P Mid-Cap 400 Growth Index Fund
Institutional Shares	$1,000.00	$1,069.90	$0.41
ETF Shares	1,000.00	1,069.23	1.03
Based on Hypothetical 5% Yearly Return
S&P Mid-Cap 400 Index Fund
Institutional Shares	$1,000.00	$1,024.40	$0.40
ETF Shares	1,000.00	1,024.05	0.75
S&P Mid-Cap 400 Value Index Fund
Institutional Shares	$1,000.00	$1,024.40	$0.40
ETF Shares	1,000.00	1,023.85	0.95
S&P Mid-Cap 400 Growth Index Fund
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 0.19% 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.

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

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

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

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

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

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

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

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

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

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

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

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

Vanguard S&P 500 Value Index Fund

Vanguard S&P 500 Growth Index Fund

The mission continues

On May 1, 1975, Vanguard began operations, a fledgling company based on the simple but revolutionary idea that a mutual fund company should be managed solely in the interest of its investors.

Four decades later, that revolutionary spirit continues to animate the enterprise. Vanguard remains on a mission to give investors the best chance of investment success.

As we mark our 40th anniversary, we thank you for entrusting your assets to Vanguard and giving us the opportunity to help you reach your financial goals in the decades to come.

Chairman’s Letter

Dear Shareholder,

For the six months ended February 28, 2015, Vanguard S&P 500 Value Index Fund and Vanguard S&P 500 Growth Index Fund produced positive results. As growth stocks trumped their value counterparts, the Growth Index Fund returned more than 8%, while the Value Index Fund returned almost 4%. (Vanguard 500 Index Fund, which is a blend of growth and value portfolios, is covered in a separate report.) Both funds successfully tracked their target indexes and surpassed the average returns of their peers.

Technology companies were the top contributors to the Growth Index Fund’s return; health care companies added most to the Value Index Fund’s return. Energy holdings detracted significantly from both.

A surge in February powered U.S. stocks

U.S. stocks performed solidly but unevenly over the six months. Despite declines in two of those months and flat returns in another, the broad U.S. stock market ended the period up about 6%.

Bonds notched positive results despite early and late retreats

Municipal bonds, which returned 2.21%, lost some steam toward the end of the period amid increased bond issuance and the prospect of higher interest rates.

Stocks
Russell 1000 Index (Large-caps)	6.00%	14.88%	16.39%
Russell 2000 Index (Small-caps)	5.70	5.63	15.97

CPI
Consumer Price Index	-1.32%	-0.03%	1.61%

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –9.54%, weighed down by the weakness of foreign currencies relative to the dollar. International bonds that were hedged to eliminate the effect of currency exchange rates produced positive returns.

Money market funds and savings accounts provided scant returns as the Fed’s target for short-term rates remained at 0%–0.25%.

Growth stocks outshone their value counterparts

The Vanguard S&P 500 Index Funds provide exposure to some of the biggest companies in the United States. The 500 Index Fund (which, as I mentioned earlier, is covered in a separate report) represents the broader market, and the Growth and Value Index Funds form portfolios from its subsets.

On balance, the market’s larger stocks outpaced their smaller counterparts during the past six months, and growth bested value. In both the Growth and Value Index Funds, most sectors posted positive returns.

Health care stocks were the market’s top performers. The largest contributors to the Value Index Fund’s return, these holdings also lifted the Growth Index Fund. Within the health care industry, new product development, mergers and acquisitions, and strategic alliances boosted pharmaceutical and biotechnology


Expense Ratios
Your Fund Compared With Its Peer Group

	Shares	Average
S&P 500 Value Index Fund	0.15%	1.13%

The fund expense ratios shown are from the prospectus dated December 19, 2014, and represent estimated costs for the current fiscal year.
For the six months ended February 28, 2015, 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 2014.

companies; innovative products and therapies helped medical equipment firms; and health care providers with diverse membership bases and business lines thrived.

The Growth Index Fund’s heavy exposure to technology (the sector accounted for more than 30% of fund assets) added nearly 3 percentage points to its total return. Although the Value Index Fund’s technology stake makes up a far smaller portion of its assets, it too benefited from the sector’s strong results. Tech companies profited from an increase in corporate IT-related spending and a surge in mobile device sales.

Consumer discretionary and consumer staples stocks also added significantly to the funds’ performance. Both sectors gained from a slide in oil prices, which freed up money consumers had previously earmarked for the gas pump. Entertainment companies, retailers, and restaurants led the way among consumer discretionary stocks; in consumer staples, food and drug retailers and household products stood out. Holdings in the financial and industrial sectors also contributed.

Energy was the only sector to post a negative result for both funds. Hurt by tumbling oil prices, stocks in this sector fell across the board, and many industries suffered double-digit losses.

Both ETFs and mutual funds offer opportunities for success

Some say that ETFs are more of a trading tool than an investment tool. We don’t think this has to be the case. In fact, we’re seeing much greater use of ETFs as part of long-term plans. Certainly, they are easy to trade. But they are also easy to hold. And, unlike with traditional mutual funds, the investor doing the trading is the one who pays the transaction costs—not the other fund shareholders.

essentially the same investment function and that investors can use both to create a low-cost, well-diversified portfolio of stocks and bonds. You can read more in Buying on the FACTS: Investors’ Choices Between ETFs and Mutual Funds at vanguard.com/research.

As always, thank you for investing with Vanguard.

Sincerely,

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, 2015; subsequently, Institutional Shares were issued on March 3, 2015. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker.

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 counter-parties, 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 counter-party risk, in the absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2015	3	315	3

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

S&P 500 Value Index Fund

During the six months ended February 28, 2015, the fund realized $12,545,000 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, 2014, the fund had available capital losses totaling $1,971,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $240,091,000. Net unrealized appreciation of investment securities for tax purposes was $27,742,000, consisting of unrealized gains of $31,343,000 on securities that had risen in value since their purchase and $3,601,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $150,465,000 of investment securities and sold $95,324,000 of investment securities, other than temporary cash investments. Purchases and sales include $100,210,000 and $43,364,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

G. Capital shares issued and redeemed were:


	Six Months Ended	Year Ended
	February 28, 2015	August 31, 2014
	Shares	Shares
	(000)	(000)
ETF Shares
Issued	1,150	1,150
Issued in Lieu of Cash Distributions	—	—
Redeemed	(500)	(450)
Net Increase (Decrease) in Shares Outstanding	650	700

H. Other than the issuance of Institutional Shares discussed above, management has determined that no material events or transactions occurred subsequent to February 28, 2015, 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, 2015. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker.

During the six months ended February 28, 2015, the fund’s average investments in long and short futures contracts each represented less than 1% and 0% of net assets, respectively, based on the average of aggregate settlement values at each quarter-end during the period.

S&P 500 Growth Index Fund

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 counter-parties, 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 counter-party risk, in the absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

The following table summarizes the market value of the fund’s investments as of February 28, 2015, based on the inputs used to value them:

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2015	2	210	4

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

S&P 500 Growth Index Fund

During the six months ended February 28, 2015, the fund realized $8,007,000 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, 2014, the fund had available capital losses totaling $1,911,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $415,942,000. Net unrealized appreciation of investment securities for tax purposes was $89,188,000, consisting of unrealized gains of $91,405,000 on securities that had risen in value since their purchase and $2,217,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $264,231,000 of investment securities and sold $116,580,000 of investment securities, other than temporary cash investments. Purchases and sales include $182,128,000 and $35,727,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

G. Capital shares issued and redeemed were:


	Six Months Ended	Year Ended
	February 28, 2015	August 31, 2014
	Shares	Shares
	(000)	(000)

Redeemed	(400)	(450)

H. Management has determined that no material events or transactions occurred subsequent to February 28, 2015, that would require recognition or disclosure in these financial statements.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2015
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	8/31/2014	2/28/2015	Period
Based on Actual Fund Return
S&P 500 Value Index Fund
ETF Shares	$1,000.00	$1,036.99	$0.76
S&P 500 Growth Index Fund
ETF Shares	$1,000.00	$1,082.16	$0.77
Based on Hypothetical 5% Yearly Return
S&P 500 Value Index Fund
ETF Shares	$1,000.00	$1,024.05	$0.75
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.

Chairman’s Letter

Dear Shareholder,

U.S. stocks logged modest gains for the six months ended February 28, 2015. Large-capitalization stocks slightly outperformed those of small companies.

Returns for the Vanguard S&P Small-Cap 600 Index Funds ranged from 8.47% for the Growth Fund to 4.02% for the Value Fund. Vanguard S&P Small-Cap 600 Index Fund, which encompasses both growth and value stocks, fell in between, with a return of 6.30%. (The returns cited in this letter are for ETF Shares based on net asset value.)

Each fund achieved its objective of closely tracking the performance of its target index, and each outpaced the average return of its peer group.

As we announced earlier, the three S&P Small-Cap 600 Index Funds and 21 other funds in Vanguard’s lineup will begin paying a dividend each quarter rather than once a year. The change, which will take effect in the third quarter of 2015, should align distributions more closely with those of the other Vanguard stock index funds and help the funds operate more efficiently.

A surge in February powered U.S. stocks

U.S. stocks performed solidly but unevenly over the six months. Despite declines in two of those months and flat returns in another, the broad U.S. stock market ended the period up about 6%.

Overall returns were propelled by a robust advance in February, when the broad market recorded its largest monthly gain since October 2011. Investors were cheered by stabilization in oil prices and guidance from the Federal Reserve that it wouldn’t raise interest rates prematurely.

After some ups and downs, international stocks returned about –3% in dollar terms. In addition to the dollar’s strength, various geopolitical issues restrained results. Stocks in emerging markets and the developed markets of the Pacific region and Europe backtracked, with emerging markets faring the worst. In local currency terms, though, international stocks rose.

Bonds notched positive results despite early and late retreats

Bond prices then fell in February as the Fed suggested that a midyear interest rate increase was an option if the economy continued to perform well. The yield of the 10-year Treasury note ended February at 2.03%, down from 2.34% six months earlier. (Bond prices and yields move in opposite directions.)

Municipal bonds, which returned 2.21%, lost some steam toward the end of the period amid increased bond issuance and the prospect of higher interest rates.

Money market funds and savings accounts provided scant returns as the Fed’s target for short-term rates remained at 0%–0.25%.

Health care stocks showed vigor, but energy companies slumped

Although large- and small-company stocks performed similarly over the six months, the story was different for growth stocks versus value. Among small companies, growth stocks—which are considered to have more earnings potential—easily outdistanced their value counterparts, which are viewed as potentially underpriced.

However, even though the returns of the S&P Small-Cap 600 Growth Index Fund and S&P Small-Cap 600 Value Index Fund diverged, health care stocks led the way across the board. The sector, which

The fund expense ratios shown are from the prospectus dated December 19, 2014, and represent estimated costs for the current fiscal year.
For the six months ended February 28, 2015, 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, 0.08% for Institutional Shares and 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 2014.

returned around 18% or more for all three Vanguard S&P Small-Cap 600 Index Funds, was boosted by merger and acquisition activity and healthy demand for health care equipment and supplies.

Technology companies—especially those in software development and system services—also outpaced the overall results for each of the three funds. The accelerating integration of information technology with business operations raised hopes for continued growth.

Consumer discretionary stocks were another highlight, as investors anticipated increased consumer spending amid rising employment. Lower energy prices were expected to help discretionary spending as well.

Financials, the largest sector in the funds, returned more than 6% for all three. Real estate investment trusts were a bright spot; the drop in interest rates benefited REITs because lower capital costs in a growing economy can help their profit margins. REITs’ regular dividends are also attractive when interest rates are low.

The clear laggard among small-caps was the energy sector. The plunge in oil prices hit energy companies hard, with the sector’s returns ranging from –33% to –43% among the three funds. Small-cap materials stocks also retreated as slowing growth in China and falling commodity prices worried investors.

Both ETFs and mutual funds offer the chance for success

essentially the same investment function, and that investors can use both to create a low-cost, well-diversified portfolio of stocks and bonds. You can read more in Buying on the FACTS: Investors’ Choices Between ETFs and Mutual Funds, available at vanguard.com/research.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

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.

S&P Small-Cap 600 Index Fund

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 in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan.

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	March 2015	11	1,355	30

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

During the six months ended February 28, 2015, the fund realized $27,169,000 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, 2014, the fund had available capital losses totaling $3,064,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $358,235,000. Net unrealized appreciation of investment securities for tax purposes was $46,673,000, consisting of unrealized gains of $62,267,000 on securities that had risen in value since their purchase and $15,594,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $157,347,000 of investment securities and sold $118,073,000 of investment securities, other than temporary cash investments. Purchases and sales include $101,751,000 and $90,770,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Net Increase (Decrease)—ETF Shares	25,612	250	62,188	650

At February 28, 2015, one shareholder was the record or beneficial owner of 28% 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, 2015, that would require recognition or disclosure in these financial statements.

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. Institutional Shares were issued on November 19, 2014. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker.

S&P Small-Cap 600 Value Index Fund

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

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

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.

S&P Small-Cap 600 Value Index Fund

The following table summarizes the market value of the fund’s investments as of February 28, 2015, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	96,779	—	—
Temporary Cash Investments	299	100	—
Futures Contracts—Liabilities¹	(1)	—	—
Total	97,077	100	—
1 Represents variation margin on the last day of the reporting period.

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	March 2015	3	369	2

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

During the six months ended February 28, 2015, the fund realized $4,832,000 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, 2014, the fund had available capital losses totaling $1,091,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $96,266,000. Net unrealized appreciation of investment securities for tax purposes was $912,000, consisting of unrealized gains of $6,562,000 on securities that had risen in value since their purchase and $5,650,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $69,113,000 of investment securities and sold $69,731,000 of investment securities, other than temporary cash investments. Purchases and sales include $29,439,000 and $37,591,000, 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:

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. During the six months ended February 28, 2015, 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.

S&P Small-Cap 600 Growth Index Fund

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

The fund had no borrowings outstanding at February 28, 2015, or at any time during the period then ended.

S&P Small-Cap 600 Growth Index Fund

The following table summarizes the market value of the fund’s investments as of February 28, 2015, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	70,817	—	—
Temporary Cash Investments	59	100	—
Futures Contracts—Liabilities¹	(1)	—	—
Total	70,875	100	—
1 Represents variation margin on the last day of the reporting period.

D. At February 28, 2015, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	March 2015	1	123	3

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

During the six months ended February 28, 2015, the fund realized $4,614,000 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, 2014, the fund had available capital losses totaling $261,000 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, 2015; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2015, the cost of investment securities for tax purposes was $67,151,000. Net unrealized appreciation of investment securities for tax purposes was $3,825,000, consisting of unrealized gains of $5,768,000 on securities that had risen in value since their purchase and $1,943,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2015, the fund purchased $66,286,000 of investment securities and sold $61,241,000 of investment securities, other than temporary cash investments. Purchases and sales include $31,150,000 and $28,965,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

1 Institutional Shares were issued and redeemed during the fiscal year ended August 31, 2014. As of February 28, 2015, there were no investors in the Institutional share class.

H. Management has determined that no material events or transactions occurred subsequent to February 28, 2015, that would require recognition or disclosure in these financial statements.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2015
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	8/31/2014	2/28/2015	Period
Based on Actual Fund Return

S&P Small-Cap 600 Growth Index Fund
ETF Shares	$1,000.00	$1,084.68	$1.03
Based on Hypothetical 5% Yearly Return
S&P Small-Cap 600 Index Fund
Institutional Shares	$1,000.00	$1,024.40	$0.40
ETF Shares	1,000.00	1,024.05	0.75
S&P Small-Cap 600 Value Index Fund
ETF Shares	$1,000.00	$1,023.80	$1.00
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. The table does not
include data for share class with less than six months of history.
