Chairman’s Letter

Dear Shareholder,

After rising dramatically throughout most of 2009, domestic stocks leveled off during the first two months of 2010. For the six-month period ended February 28, 2010, the broad U.S. stock market posted a return of about 10%.

Vanguard U.S. Growth Fund returned about 8% for the first half of its fiscal year, an acceptable result that could have been better. The fund lagged the broad market for the period and also fell behind its benchmark, the Russell 1000 Growth Index, which returned about 11%. The fund’s trailing performance was primarily due to poor stock selection in the financial and information technology sectors of the market.

Stock markets caught their breath at the end of a solid six months
The broad stock market rally seemed to downshift toward the end of the fiscal period, as the investor relief that powered markets higher a year ago gave way to a sober-minded assessment of the prospects for corporate earnings growth.

Smaller-capitalization stocks did a little better than larger-cap stocks, and growth-oriented securities bested their value-oriented counterparts, but the uniformity of returns from different market segments was more striking than the differences.

International stocks produced more modest returns. In Europe, the precarious financial health of Greece and of smaller economies such as Portugal and Ireland weighed on the markets. In Asia, the Japanese stock market’s weakness held back results for Asia Pacific indexes. Emerging market stocks continued to outpace those from developed markets.

Yields remained low, but Fed began to unwind rescue programs
The yields of longer-term U.S. Treasury bonds rose during the past six months, while those of the shortest-term securities remained near 0%. Although the Federal Reserve Board expects to keep its target for short-term interest rates close to 0% for “an extended period,” it began to wind down credit programs established during the financial crisis. The Fed’s most dramatic (though largely symbolic) act was to raise the interest rate at its discount window, a lending facility designed to help commercial banks and other depository institutions meet emergency short-term funding needs.

The broad taxable bond market returned 3.19%, with notable strength in corporate bonds. The broad municipal bond market returned 4.13%.

Poor stock selection hindered fund performance
During the six-month period covered in this report, Vanguard U.S. Growth Fund posted positive returns in almost all areas of the market, with the exception of the financial and utilities sectors. Although the fund’s overall performance was respectable in

absolute terms, the fund trailed its benchmark by about 3 percentage points for the period.

The U.S. Growth Fund allocated about 12% of its assets to financial stocks, on average, during the period, compared with an index weighting of about 5%. The fund had significant exposure to capital market stocks, including investment firms Goldman Sachs, JPMorgan Chase, and Credit Suisse. These stocks took a hit during the period, as investors continued to be skeptical of big financial institutions.

Information technology stocks accounted for the largest sector weighting in both the fund and index for the period. Technology companies have remained among the U.S. stock market’s top performers since the rally in equities began in March 2009; however, poor stock selection in the sector dampened the fund’s returns. A large exposure to the communications company Qualcomm—which returned –20% for the period—particularly hurt performance. Fortunately, holdings in some of the industry’s top performers, including Apple, Hewlett-Packard, and Google, helped to soften the blow.

Relative to the index, the fund had less of a stake in consumer staples stocks, which also impeded returns. Minimal exposure to food retailers, beverage companies, and household products firms caused the fund to trail its benchmark by more than 1 percentage point in the sector.

On a positive note, the portfolio had strong stock selection in health care and industrials. In health care, the fund’s holdings in biotech companies, including Gilead Sciences and Celgene, boosted returns. These companies saw their stock prices rise as investors’ concerns over changes to the nation’s health care policy began to dissipate. In industrials, the machinery company Danaher, which returned almost 22%, was one of the fund’s leading contributors to performance for the six months.

Long-term performance should always be your focus
After one of the most volatile periods on record, the U.S. financial markets began to rally in March 2009 and stocks made a dramatic comeback. Although stocks have continued to post healthy gains, it’s impossible to know for sure whether the market will continue to climb.

While we can’t control what happens in the financial markets, we can control how we invest our hard-earned money. That’s why, at Vanguard, we urge investors to create and stick with an investment plan that includes a mix of stocks, bonds, and short-term investments that is appropriate for their long-term goals and risk tolerance. Such a well-balanced portfolio can offer some protection during a down market, while also providing an opportunity for long-term growth.

At the end of June, James G. Reilly, an AllianceBernstein portfolio manager who oversees a portion of Vanguard U.S. Growth Fund, plans to retire. We thank Jim for his dedication to the fund’s shareholders. We remain confident that the fund's low-cost, research-intensive approach to large-cap growth stocks can play a useful role in a portfolio.

On another matter, I would like to inform you that as of January 1, 2010, we completed a leadership transition that began in March 2008. I succeeded Jack Brennan as chairman of Vanguard and each of the funds. Jack has agreed to serve as chairman emeritus and senior advisor. Under Jack’s leadership, Vanguard has grown to become a preeminent firm in the mutual fund industry. Jack’s energy, his relentless pursuit of perfection, and his unwavering focus on always doing the right thing for our clients are evident in every facet of Vanguard policy today.

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

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Advisors’ Report

For the half-year ended February 28, 2010, Vanguard U.S. Growth Fund returned 8.38% for Investor Shares and 8.49% for the lower-cost Admiral Shares. Your fund is managed by two independent advisors, a strategy that enhances the fund’s diversification by providing exposure to distinct, yet complementary, investment approaches. It’s not uncommon for different advisors to have different views about individual securities or the broader investment environment.

The table below lists the advisors, the amount and percentage of fund assets each manages, and brief descriptions of their investment strategies. The advisors have provided the following assessment of the investment environment during the past six months and the notable successes and shortfalls in their portfolios. These comments were prepared on March 16, 2010.

For the six months ended February 28, U.S. equities gained amid gradually growing investor confidence that an economic recovery was under way. Increased merger-and-acquisition activity also boosted investor sentiment. Growth outperformed value during the reporting period, as investors began to show a more

discriminating attitude toward risk, unlike most of 2009, when investors arbitrarily embraced stocks that had sold off more precipitously during the downturn.

We expect investor discrimination to increase going forward, as the market’s attention increasingly shifts to companies with strong growth prospects built on solid fundamentals, precisely the type of investments that we seek. Meanwhile, a number of important market and economic dynamics appear to favor the higher-quality growth stocks that we emphasize in our portfolios.

The extraordinarily low interest rates that have accompanied the recession have muted the importance of strong balance sheets. As interest rates inevitably rise, companies with weaker balance sheets are likely to become less appealing to investors. This could favor large, stable growth companies and our less-leveraged portfolio.

The portfolio’s underperformance during the reporting period can largely be attributed to our positions in JPMorgan Chase and Goldman Sachs, our two largest holdings in financials, as continued market anxiety caused short-term performance volatility. We remain committed to these holdings, relying on our research for a longer-term perspective. Both have strong capital ratios that are well above required levels. They are gaining share in key market segments, and their credit picture is improving. Their valuations relative to book value are very attractive, and they have consistently beaten earnings expectations. Return on equity has been strong and is expected to continue improving.

Nonetheless, their stock prices have recently taken a hit. There’s no question that talk of regulatory reform raises broad uncertainty in the industry, but these are key players that should overcome difficulties resulting from reform efforts. Yet investors are pricing in exaggerated risk, in our view. If the pattern with health care, the portfolio’s largest contributor for the reporting period, is any indication, these stocks stand to come back strongly once the uncertainty over the impact of federal regulation begins to subside and investors again focus on fundamentals.

Overall, we believe that superior growth fundamentals will reap superior rewards over time, and that the portfolio is well positioned to take advantage of the opportunity that exists for growth. Our positioning is well supported by our research, and we expect to be ultimately rewarded as the cycle continues.

John F. Jostrand, CFA, Principal

As the economic recovery continued, U.S. equity markets rose substantially in the last six months, as demonstrated by the Russell 1000 Growth Index’s return of 11.3%. Performance was volatile, and all of the gains occurred in 2009. Given the massive government intervention in the global economy, stock movements, particularly early in this period, were

driven by more macroeconomic factors as investors turned to stocks that were heavily sold early in 2009.

In 2010, some investors took profits amid concerns about the sustainability of the economic recovery, the potential for rising interest rates, and sovereign debt issues. The Russell 1000 Growth’s return for the first two months in 2010 was –1.1%.

For the six-month period, growth stocks outperformed value stocks and mid-capitalization stocks were notably stronger than larger-cap stocks.

In this environment, our portion of the portfolio had strong absolute returns, but trailed its benchmark. There were stock-specific issues with CVS Caremark and Qualcomm, two larger positions at the beginning of the period. CVS Caremark fell as a result of integration issues in its pharmacy benefit manager division. Early this year, we eliminated the stock to take advantage of other opportunities we felt more strongly about. Qualcomm declined because of a disappointing outlook for revenue growth resulting from a lower average selling price estimate for mobile handsets. We continue to believe that the company will have strong earnings power going forward.

In addition, the portfolio remains overweighted in the technology sector; these companies have strong balance sheets with large cash reserves and productivity-enhancing product offerings, which should benefit from increased demand in an improving economy.

The portfolio benefited from strong selection in industrials, particularly positions in Rockwell Automation and J.B. Hunt Transport Services. Both stocks had solid earnings results and are well positioned to take advantage of improved demand and increased volumes as the economy recovers. We added to select industrial companies during the period based on their earnings growth potential and relative valuation, increasing our emphasis on the sector in comparison with the benchmark weighting.

Our energy stocks also contributed nicely. EOG Resources and Apache, for example, each had strong earnings reports. Tighter crude oil supply and demand, improved global and U.S. economic growth, and continued strength in broader markets should be positive news for energy stocks.

In 2010, we believe investors will focus on a company’s ability to increase its earnings through a revival in sales, rather than on earnings that grow because of cost cutting or macroeconomic factors. This environment should favor stock pickers. Our quality growth investment process should assist us in identifying industry-leading companies with competitive products and services, durable business models, compelling earnings profiles, and strong financial positions.

U.S. Growth Fund

Notes to Financial Statements

Vanguard U.S. Growth 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, Investor Shares and

Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, tenure, and account-size criteria.

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

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 objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market va lues of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

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

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, 2006–2009), and for the period ended February 28, 201 0, and has concluded that no prov ision for federal income tax is required in the fund’s financ ial statements.

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

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

U.S. Growth Fund

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

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing an d distribution expenses are alloc ated to each class of shares base d 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. AllianceBernstein L.P. and William Blair & Company, L.L.C., each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fees are subject to quarterly adjustments based on performance relative to the Russell 1000 Growth Index over the preceding three years for AllianceBernstein and over the preceding five years for William Blair & Company.

The Vanguard Group manages the cash reserves of the fund on an at-cost basis.

For the six months ended February 28, 2010, the aggregate investment advisory fee represented an effective annual basic rate of 0.16% of the fund’s average net assets, before a decrease of $454,000 (0.02%) based on performance.

C. The Vanguard Group furnishes at cost corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $760,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.30% of

Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. For the six months ended February 28, 2010, these arrangements reduced the fund’s expenses by $118,000 (an annual rate of 0.01% of average net assets).

E. 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 quo ted 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).

U.S. Growth Fund

The following table summarizes the fund’s investments as of February 28, 2010, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	3,795,722	—	—
Temporary Cash Investments	130,330	17,978	—
Futures Contracts—Assets¹	101	—	—
Total	3,926,153	17,978	—
1 Represents variation margin on the last day of the reporting period.

F. At February 28, 2010, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
S&P 500 Index	March 2010	157	43,308	(86)
S&P Mid-Cap 400 Index	March 2010	106	39,098	1,358
E-mini S&P 500 Index	March 2010	375	20,689	168

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

G. 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 shor t-term gains as ordinary income for tax purposes.

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, 2009, the fund had available capital loss carryforwards totaling $6,398,578,000 to offset future net capital gains of $2,582,798,000 through August 31, 2010, $2,548,333,000 through August 31, 2011, $887,490,000 through August 31, 2012, $123,651,000 through August 31, 2013, and $256,306,000 through August 31, 2017. In addition, the fund realized losses of $316,709,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

U.S. Growth Fund

At February 28, 2010, the cost of investment securities for tax purposes was $3,779,063,000. Net unrealized app reciation of investment securities for tax purposes was $164,967,000, consisting of unrealized gains of $311,613,000 on securities that had risen in value since their purchase and $146,646,000 in unrealized losses on securit ies that had fallen in value since their purchase.

H. During the six months ended February 28, 2010, the fund purchased $1,490,926,000 of investment securities and sold $1,683,583,000 of investment securities, other than temporary cash investments.

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

J. In preparing the financial statements as of February 28, 2010, management considered the impact of subsequent events for potential 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 the account service fee described in the prospectus. If such a fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.” The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

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


Six Months Ended February 28, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
U.S. Growth Fund	8/31/2009	2/28/2010	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,083.81	$2.48
Admiral Shares	1,000.00	1,084.92	1.50
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.41	$2.41
Admiral Shares	1,000.00	1,023.36	1.45

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.48% for Investor Shares and 0.29% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Trustees Approve Advisory Agreements

The board of trustees of Vanguard U.S. Growth Fund has renewed the fund’s investment advisory agreements with AllianceBernstein L.P. and William Blair & Company, L.L.C. The board determined that the retention of these advisors was in the best interests of the fund and its shareholders.

The board based its decision upon an evaluation of each advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the agreements. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services
The board considered the quality of the fund’s investment management over both the short and long term and took into account the organizational depth and stability of each advisor. The board noted the following:

AllianceBernstein. Founded in 1971, AllianceBernstein is a leading global investment management firm. The investment team at AllianceBernstein seeks out companies likely to increase earnings faster and/or sustain them longer than consensus estimates. The team defines growth broadly, beyond forecast growth, to be flexible across sectors and company life cycles. The team looks to internal research to identify and evaluate the most attractive investment opportunities, believing that rigorous, insightful analysis is essential to successful long-term performance. AllianceBernstein has managed a portion of the fund since 2001.

William Blair & Co. Founded in 1935, William Blair is an independently owned, full-service investment firm. The firm uses an investment process that relies on thorough in-depth fundamental analysis.

Based on this process, the advisor invests in companies that it believes are of high quality and that have sustainable, above-average growth. In selecting stocks, the advisor considers each company’s leadership position within the market it serves, the quality of products or services it provides, its return on equity, its accounting policies, and the quality of the management team. William Blair has advised a portion of the fund since 2004.

The board concluded that each advisor’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory agreements.

Investment performance
The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of a rel evant benchmark and peer group. The board concluded that the advis ors have carried out the fund’s investment strategy in a disciplined fashion, and that the results have been mixed—with periods of outperformance and periods of underperformance versus its benchmark and peer group. Information about the fund’s most recent performance can be found in the Performance Summary section of this report.

Cost
The board concluded that the fund’s expense ratio was well below the average expense ratio charged by funds in its peer group and that the fund’s advisory fee rate was also well below its peer-group average. Information about the fund’s expense ratio appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements section, which also includes information about the fund’s advisory fee rate.

The board did not consider the profitability of the fund’s advisors in determining whether to approve the advisory fees, because the firms are independent of Vanguard, and the advisory fees are the result of arm’s-length negotiations.

The benefit of economies of scale
The board concluded that the fund’s shareholders benefit from economies of scale because of breakpoints in the advisory fee schedules. The breakpoints reduce th e effective rate of the fees as the fund’s assets managed by each firm increase.

The board will consider whether to renew the advisory agreements again after a one-year 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 (in the case of bonds) or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the fund’s actual experience. As a result, the fund’s income distributions may be higher or lower than implied by the SEC yield.

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

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

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

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

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

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

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

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

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

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

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

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

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

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

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 161 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 Informatio n, which can be obtained, wit hout charge, by contacting Vanguard at 800-662-7447, or online at www.vanguard.com.

Chairman’s Letter

Dear Shareholder,

For the six months through February 2010, Vanguard International Growth Fund returned about 5%, an unexceptional result compared with the dizzying highs and lows of the previous two years. Although the international stock markets have snapped backed strongly from the global financial crisis, their gains have been restrained recently by the still-fragile nature of the economic recovery.

The fund’s return surpassed both the average return of its peer funds and the return of its market benchmark, the MSCI EAFE Index. Emerging markets, which are not included in the index, drove most of the fund’s gains, but it also recorded solid relative performance in the developed markets of the European and Pacific regions.

Seven of the fund’s ten sectors advanced. Relative to the benchmark, the fund benefited from the advisors’ limited exposure to, and strong stock selection in, the financial sector, one of the period’s weakest areas.

Stock markets caught their breath at the end of a solid six months
For the six months, the broad U.S. stock market returned about 10%. The rally seemed to downshift toward the end of the period, as the relief among investors that had powered markets higher gave way to sober-minded assessment of corporate earnings-growth prospects.

Smaller-capitalization stocks did a little better than larger-caps, and growth-oriented securities bested their value-oriented counterparts, but the uniformity of returns from varied market segments was more striking than the differences.

International stocks produced more modest returns. In Europe, the precarious financial health of Greece and smaller economies such as Portugal and Ireland weighed on the markets. In Asia, the Japanese stock market’s weakness held back results for regional indexes. Emerging market stocks continued to outpace those in developed markets.

Yields stayed low, but Fed began to unwind its rescue programs
The yields of longer-term U.S. Treasury bonds rose during the six months, while those of the shortest-term securities remained near 0%. Although the Federal Reserve Board expects to keep its target for short-term interest rates close to zero percent for “an extended period,” it began to wind down credit programs established during the financial crisis.

The Fed’s most dramatic (though largely symbolic) act was to raise the interest rate at its discount window, a lending facility designed to help commercial banks and other depository institutions meet emergency short-term funding needs.

The broad taxable bond market returned 3.19%, with notable strength in corporate bonds. The broad municipal bond market returned 4.13%.

For the fund, a calm half-year follows the drama of 2009
Vanguard International Growth Fund settled into a more pedestrian pace in the first six months of fiscal 2010 following a return of about 56% in the previous half-year. Although international investors’ mood seemed to brighten, several developments tempered their optimism, including debt scares in Dubai and Greece. For U.S.-based investors, the dollar’s six-month climb, while boosting Americans’ purchasing power in most markets abroad, also chipped away at the dollar value of assets denominated in other currencies.

Against this backdrop, the International Growth Fund outperformed its benchmark index and the average return of peer funds. In contrast with the fund’s six-month gain of about 5%, the MSCI EAFE Index returned less than 1% and international funds advanced less than 3% on average.

The fund outperformed the EAFE Index in both Europe and the Pacific region, but gained most of its advantage from emerging markets, which are not a component of the index. The fund’s advisors added to their emerging market

holdings during the global financial crisis, and the benefits of this positioning have been realized over the past 12 months.

The fund’s Chinese holdings rose about 23% overall, aided in particular by stocks of information technology and consumer discretionary companies. These stocks have rallied as the Chinese economy, after a brief pause, again kicked into high gear. Brazilian holdings gained approximately 20%, sparked by energy, materials, and financial stocks. Petrobras, the Brazilian oil giant and one of the fund’s largest holdings, benefited from the rising price of oil.

In the developed European and Pacific markets, the fund gained an advantage over the benchmark index by avoiding some of the worst-performing financial companies and holding some of the winners. Successful stock selection was also evident in the consumer discretionary, energy, materials, and information technology sectors. The fund lagged the benchmark return in only two sectors, industrials and telecommunication services.

The International Growth Fund’s commendable performance is a testament to the diligent and disciplined approach of its advisors. Schroder Investment Management North America has managed the fund since its 1981 inception. Baillie Gifford Overseas joined the fund in 2003, and M&G Investment Management Limited came aboard in 2008.

Relative to competitors, the fund also benefits from exceptionally low expenses, as you can see in the table on page 4.

International investments provide diversification
International stocks, as measured by market indexes, trailed their domestic counterparts during the past six months by about six percentage points after both enjoyed historic rallies earlier in 2009. Over the past five and ten years, markets abroad have held a slight edge, whereas U.S. stocks did better throughout the 1990s.

While foreign markets often move in the same direction as the U.S. market, they also frequently diverge, sometimes significantly. The past half-year is a case in point, and international fund investors may have been disappointed by the results. This divergent performance, however, is the essence of diversification. Relative performance ebbs and flows. Over time, combining investments with varying patterns of return can help you reduce the volatility that may be associated with a narrowly focused portfolio.

Vanguard counsels investors to build a diversified portfolio that includes not just U.S. and international stocks, but also bond and money market funds, with the allocations tailored to the investor’s own goals, time horizon, and risk tolerance. The International Growth Fund can play an important role in such a portfolio.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Advisors’ Report

For the fiscal half-year ended February 28, 2010, Vanguard International Growth Fund returned about 5%. Your fund is managed by three independent advisors, a strategy that enhances the fund’s diversification by providing exposure to distinct, yet complementary, investment approaches. It is not uncommon for different advisors to have different views about individual securities or the broader investment environment.

The advisors, the percentage of fund assets each manages, and brief descriptions of their investment strategies are presented in the table below. The advisors have also prepared a discussion of the investment environment that existed during the fiscal half-year and of how the portfolio’s positioning reflects this assessment. These comments were prepared on March 16, 2010.

The strong performance of equity markets has slowed in recent months as several uncertainties took the edge off investors’ appetite for risk. These included the lack of clarity surrounding bank regulation, sovereign debt risk (notably in Greece, but even in the United Kingdom), and concerns about how central banks will go about normalizing currently ultra-loose monetary conditions.

European markets came under pressure as Greece revealed worse-than-expected fiscal problems, leading to sharply increasing sovereign debt spreads. Greece’s troubles fed fears that Spain and Portugal would ultimately face similar difficulties, and those concerns in turn put pressure on commercial banks. Global banks’ exposure to Spanish, Portuguese, and Greek debt has been estimated at $1.3 trillion, with a high proportion carried by German and French banks. Our exposure in Europe is concentrated in quality companies with global franchises, such as Danone (consumer staples), ArcelorMittal (materials), Roche Holdings (health care), and BG Group (energy).

Emerging markets and Asian developed markets (excluding Japan) provided strong returns during the period. Despite a year-end rally prompted by signs of a weakening yen, which could boost exports, Japanese securities fell during the period overall. We took profits in some strongly performing emerging market and Pacific holdings, selling our stakes in Shangri-La Asia in Hong Kong and Grupo Televisa in Mexico, as well as trimming our holdings of Teva Pharmaceutical Industries in Israel.

We outperformed our benchmark in all but one sector, and in all regions. Our strongest returns came from the financial sector, where our commitment to quality was rewarded as we steered clear of banks that needed large capital infusions and faced the biggest losses. The financial stocks that contributed the most for us were insurance companies (AXA Group) and firms benefiting from stronger consumption trends in Asian emerging markets (Swire Pacific, China Pacific Insurance, and Ping An Insurance) and in Latin America (BM&FBOVESPA and Itau Unibanco).

In the consumer discretionary sector, the portfolio benefited from our exposure to Chinese consumers. Notable contributors included China Resources Enterprise (retail and food processing) and Ctrip.com International (online travel).

Finally, our health care holdings have been an area of strength, one that we have added to during the period. We own companies such as Fresenius Medical Care (kidney dialysis), Teva Pharmaceuticals, and Novartis, all catering to aging populations in the West. We believe the market is underestimating the long-term earnings growth potential of these companies.

From a regional standpoint, our holdings in emerging markets and Japan contributed the most to relative performance. In Japan, our exposure to global companies, such as Mitsubishi, Honda Motor (which has a leading position in fuel-efficient engine technology), and Canon, led the outperformance.

Looking forward, we believe that markets will remain volatile in 2010, warranting a strong focus on valuation and quality. Much uncertainty exists about how and when authorities will act to normalize monetary policies around the world. Interestingly, while the world was mostly united to fight the financial crisis in 2008 and 2009, 2010 may show a divergence in focus. As the recovery strengthens in countries such as Australia, China, and Brazil, along with most of Asia outside Japan, those countries will attempt to slow their economic growth to avert potential inflationary pressure; meanwhile, most developed countries will still be struggling to stimulate their economies. This situation will create “push and pull” forces globally that will add to volatility.

Furthermore, the implementation of financial-sector regulations, such as the Basel 3 recommendations, will not support bank lending at a time when governments in most developed markets cannot afford further measures to address the lending gap. From a company perspective, this dynamic will provide strong marginal competitive advantages to quality companies that possess sizable cash flows and do not depend on borrowing to grow their business. In addition, one benefit of the financial crisis is that many companies are currently in a “sweet spot,” as they have cut their cost bases and should see profits continue to increase while labor costs remain largely in check.

Overall, we believe that the continuing market volatility will create attractive price opportunities in quality growth stocks with strong and sustainable medium-term competitive advantages and earnings growth.

During the six months through February 2010, investors’ overall relief, which had powered the rally last summer, became more discriminating. Investors were concerned about the strength and durability of the economic recovery, especially in some of the mature markets. Brazil and China continued to produce good market returns over the period as their economies powered ahead, but Europe and Japan were dull at best, and some of the small southern European markets fell quite sharply. The problems of Greece have few global implications, except to remind us that the legacy of debt cannot easily be sloughed off.

The sectors that depend most on a strong recovery in the mature economies were the feeblest performers in the

period. So the big utilities, banks, and telecommunications companies were weak. There is a great deal of market capitalization tied up in these businesses; the phrase “All dressed up and nowhere to go” springs to mind.

On the other hand, those sectors with good long-term prospects, such as raw materials and technology, did well. Supplying the developing world or doing something that the Chinese cannot do more cheaply is a winning strategy.

Company profits and cash flows were generally very strong over the period, and not just because of cost-cutting. A strong industrial recovery is taking place. It is partly because of inventory rebuilding, but mainly reflects increasing demand, especially from Asia. Housing, employment, and consumption are laggards, especially in the mature economies. It may take them a while to catch up, especially if the saving habit becomes deeply embedded. In that case, monetary policy would likely remain loose for a long time, which should be good for real assets, such as stocks, and less good for nominal ones, such as bonds.

We did not change the portfolio’s positioning very much during the half-year. Our policy is optimistic with a bias toward the developing world and technology, so we are overweighted in computer software, capital goods, and retailing. We have tended to avoid utilities, pharmaceuticals, and telecoms. Our search for growth has not tempted us to alter this strategy, rather the opposite; but, as always, the main factor for us is the availability of good companies.

The coming months are likely to see further strains in the foreign exchanges, as currency markets try to reflect both the success of China and the unsustainable size of government debt in some of the mature countries (including those in which the writer and readers of this note live). Stock prices still do not reflect reality concerning where risk and return are likely to arise, and this presents us with an opportunity to add value as the global recovery gradually accelerates.

In spite of high volatility, global equities posted healthy gains for the fiscal half-year as investors focused on the improving prospects for a broad-based economic recovery, while company earnings results generally outpaced expectations. Investors’ increased appetite for risk prompted an especially strong rally in emerging market and commodities-related stocks.

Against this backdrop, our holdings that were exposed to growth in developing markets, recovering consumer spending, and rising demand for natural resources proved particularly beneficial. We received

strong returns from a range of companies, including China’s leading supplier of agricultural produce, Chaoda Modern Agriculture Holdings, Taiwanese electronics manufacturer Compal Electronics, and Brazilian miner Vale, the world’s largest iron ore producer.

By contrast, our holdings with perceived exposure to slower-growing industries and regions performed weakly. For example, Austrian brick manufacturer Wienerberger suffered from fragility in European construction markets, Japanese auto manufacturer Toyota Motor was hurt by the company’s well-publicized vehicle recalls, and French bank Societe Générale reported weaker-than-expected investment banking returns and cut its dividend for 2009.

In spite of volatile investor sentiment during the past year, the portfolio has consistently focused on high-quality, value-creating businesses in both defensive and cyclical areas whose holdings of scarce assets differentiate them from their competitors. During the period, we continued to invest in those companies that we believe can deliver sustainable returns above their cost of capital and boost their profits through reinvestment. Additions to our portfolio include well-positioned U.K./U.S. cruise operator Carnival, Germany’s Wincor Nixdorf, a leading global provider of cash machines and payment systems for the financial and retail industries, and French-listed CFAO, a specialized distributor in Africa and French territories around the world.

Among sales in our portfolio, we took some profits from some of our strongest performers, including Taiwanese electronics manufacturer Compal Electronics and South Korean tire manufacturer Hankook Tire. We also closed a position in Dutch financial institution ING Groep after a sharp rise in the company’s share price provided a suitable exit point.

International Growth Fund

Notes to Financial Statements

Vanguard International Growth Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in securities of foreign issuers, which may subject it to investment risks not normally associated with investing in securities of U.S. corporations. The fund offers two classes of shares: Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, tenure, and account-size criteria.

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 affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued at their fair values calculated according to procedures adopted by the board of trustees. These procedures include obtaining quotations from an independent pricing service, monitoring news to identify significant market- or security-specific events, and evaluating changes in the va lues of foreign market proxies (for example, ADRs, futures contracts, or exchange-traded funds), between the time the foreign markets close and the fund’s pricing time. When fair-value pricing is employed, the prices of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities. 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. Foreign Currency: Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates obtained from an independent third party as of the fund’s pricing time on the valuation date. Realized gains (losses) and unrealized appreciation (depreciation) on investment securities include the effects of changes in exchange rates since the securities were purchased, combined with the effects of changes in security prices. Fluctuations in the value of other assets and liabilities resulting from changes in exchange rates are recorded as unrealized foreign currency gains (losses) until the assets or liabilities are settled in cash, at which time they are recorded as realized foreign currency gains (losses).

3. Futures and Forward Currency Contracts: The fund uses index futures contracts to a limited extent, with the objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. 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.

The fund may also enter into forward currency contracts to provide the appropriate currency exposure related to any open futures contracts or to protect the value of securities and related receivables and payables against changes in foreign exchange rates. The primary risk associated with the fund’s use of these contracts is that a counterparty will fail to fulfill its obligation to pay gains due to the fund under

International Growth Fund

the contracts. Counterparty risk is mitigated by entering into forward currency contracts only with highly rated counterparties, by a master netting arrangement between the fund and the counterparty, and by the posting of collateral by the counterparty. The forward currency contracts contain provisions whereby a counterparty may terminate open contracts if the fund’s net assets decline below a certain level, triggering a payment by the fund if the fund is in a net liability position at the time of the termination. The payment amount would be reduced by any collateral the fund has posted. Any securities posted as collateral for open contracts are noted in the Statement of Net Assets.

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

4. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. Fees assessed on redemptions of capital shares are credited to paid-in capital.

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. Schroder Investment Management North America Inc., Baillie Gifford Overseas Ltd., and M&G Investment Management Ltd. each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fees of Schroder Investment Management North America Inc. and Baillie Gifford Overseas Ltd. are subject to quarterly adjustments based on performance for the preceding three years relative to the Morgan Stanley Capital International Europe, Australasia, Far East Index. The basic fee of M&G Investment Management Ltd. is subject to quarterly adjustments based on the fund’s performance since February 29, 2008, relative to the MSCI All Country World Index excluding USA.

International Growth Fund

The Vanguard Group manages the cash reserves of the fund on an at-cost basis.

For the six months ended February 28, 2010, the aggregate investment advisory fee represented an effective annual basic rate of 0.13% of the fund’s average net assets, before an increase of $2,127,000 (0.03%) based on performance.

C. The Vanguard Group furnishes at cost corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $3,024,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 1.21% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. For the six months ended February 28, 2010, these arrangements reduced the fund’s expenses by $100,000 (an annual rate of 0.00% of average net assets).

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

The following table summarizes the fund’s investments as of February 28, 2010, based on the inputs used to value them:


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

Unrealized appreciation (depreciation) on open FTSE 100 Index futures contracts is required to be treated as realized gain (loss) for tax purposes.

International Growth Fund

At February 28, 2010, the fund had open forward currency contracts to receive and deliver currencies as follows. Unrealized appreciation (depreciation) on open forward currency contracts is treated as realized gain (loss) for tax purposes.

JPY—Japanese yen.
USD—U.S. dollar.

The fund had net unrealized foreign currency gains of $455,000 resulting from the translation of other assets and liabilities at February 28, 2010.

During the six months ended February 28, 2010, the fund realized net foreign currency losses of $551,000, which decreased distributable net income for tax purposes; accordingly, such losses have been reclassified from accumulated net realized losses to undistributed net investment income. Certain of the fund’s investments are in securities considered to be “passive foreign investment companies,” for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. Unrealized appreciation through October 31, 2009, on passive foreign investment company holdings at February 28, 2010, was $547,000, all of which has been distributed and is reflected in the balance of undistributed net investment income.

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, 2009, the fund had available capital loss carryforwards totaling $1,198,712,000 to offset future net capital gains through August 31, 2017. In addition, the fund realized losses of $2,008,606,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

International Growth Fund

At February 28, 2010, the cost of investment securities for tax purposes was $14,189,593,000. Net unrealized appreciation of investment securities for tax purposes was $1,171,992,000, consisting of unrealized gains of $2,270,185,000 on securities that had risen in value since their purchase and $1,098,193,000 in unrealized losses on securities that had fallen in value since their purchase.

H. During the six months ended February 28, 2010, the fund purchased $3,882,872,000 of investment securities and sold $3,187,935,000 of investment securities, other than temporary cash investments.

J. In preparing the financial statements as of February 28, 2010, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

About Your Fund’s Expenses

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

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 the 2% fee on redemptions of shares held for less than two months, nor do they include the account service fee described in the 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.


Six Months Ended February 28, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
International Growth Fund	8/31/2009	2/28/2010	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,050.59	$2.64
Admiral Shares	1,000.00	1,051.56	1.68
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.22	$2.61
Admiral Shares	1,000.00	1,023.16	1.66

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.52% for Investor Shares and 0.33% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Trustees Approve Advisory Agreements

The board of trustees of Vanguard International Growth Fund has renewed the fund’s investment advisory agreements with Schroder Investment Management North America Inc. (Schroder Inc.), Baillie Gifford Overseas Ltd., and M&G Investment Management Limited, as well as the sub-advisory agreement with Schroder Investment Management North America Ltd. The board determined that the retention of the advisors was in the best interests of the fund and its shareholders.

Nature, extent, and quality of services
The board considered the quality of the fund’s investment management over both the short and long term, and took into account the organizational depth and stability of each advisor. The board noted the following:

Schroder Investment Management North America Inc. Schroder Inc. is a subsidiary of Schroders plc., a firm founded more than 200 years ago, with investment management experience dating back to 1926. The advisor employs a sound process, selecting attractive growth stocks from developed and emerging markets outside the United States. Stocks are chosen using a bottom-up approach supported by Schroder’s worldwide network of analysts, economists, and strategists. The firm has advised the fund since its inception in 1981.

Baillie Gifford Overseas Ltd. Baillie Gifford, a unit of Baillie Gifford & Co., founded in 1908, is among the largest independently owned investment management firms in the United Kingdom. The advisor employs a sound process to build a diversified portfolio of high-quality non-U.S. growth stocks from developed and emerging markets. Stocks are selected using fundamental research conducted by Baillie Gifford’s Edinburgh-based analysts. The firm has advised a portion of the International Growth Fund since 2003.

M&G Investment Management Limited. M&G, founded in 1931, is based in London, England, and specializes in managing equity and fixed income portfolios for both institutional and retail clients worldwide. The advisor employs a sound process to build a diversified portfolio of high-quality, non-U.S. growth stocks from developed and emerging markets. The advisor’s global equity team—made up of the portfolio managers, Greg Aldridge and Graham French, and eight other portfolio managers/analysts—conducts intensive fundamental analysis on companies, including regular company visits. The firm has advised a portion of the fund since 2008.

The board concluded that each advisor’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory agreements.

Investment performance
The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of a relevant benchmark and peer group. The board concluded that the advisors have carried out the fund’s investment strategy in a disciplined fashion, and the performance results have allowed the fund to remain competitive versus its benchmark and its average peer fund. Information about the fund’s most recent performance can be found in the Performance Summary section of this report.

Cost
The board concluded that the fund’s expense ratio was well below the average expense ratio charged by funds in its peer group and that the fund’s advisory fee rate was also well below its peer-group average. Information about the fund’s expense ratio appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements section, which also includes information about the fund’s advisory fee rate.

The board did not consider profitability of the fund’s advisors in determining whether to approve the advisory fees, because the firms are independent of Vanguard and the advisory fees are the result of arm’s-length negotiations.

The benefit of economies of scale
The board concluded that the fund’s shareholders benefit from economies of scale because of breakpoints in the fund’s advisory fee schedules. The breakpoints reduce the effective rate of the fee as the fund’s assets managed by each firm increase.

The board will consider whether to renew the advisory agreements again after a one-year period.

Chairman’s Letter

Dear Shareholder,

For the six months ended February 28, 2010, the FTSE Social Index Fund returned about 9%, in line with its benchmark index. Like its index, the fund finished about 1 percentage point behind the broad U.S. market, as the fund’s comparatively heavy representation in financial stocks—almost twice that of the market—weighed on performance. The fund also finished a bit behind the average return of large-capitalization growth funds.

Stock markets caught their breath at the end of a solid six months
For the six months, the broad U.S. stock market returned about 10%. The rally seemed to downshift toward the end of the period, as the investor relief that lifted markets higher a year ago gave way to sober-minded assessment of corporate earnings-growth prospects.

held back results for Asia Pacific indexes. Emerging market stocks continued to outpace those from developed markets.

The broad taxable bond market returned 3.19%, with notable strength in corporate bonds. The broad municipal bond market returned 4.13%.

Weakness in financial services, but strength in tech
The fund seeks to track the return of the FTSE4Good US Select Index, which is made up of companies that, according to the index provider, work to protect the environment, have fair hiring and promotion practices for women and minorities, and maintain safe and healthy workplace

policies. The resulting portfolio is weighted substantially in financial, information technology, health care, and consumer discretionary stocks. Conversely, the fund has relatively modest exposure to the energy sector and therefore benefited little from the strong performance of those energy stocks it did hold. The sector’s surge was powered by rising energy demand as the global economy began to recover.

The fund’s financial stocks, which accounted, on average, for almost 30% of assets, posted anemic returns for the six months. While regional bank stocks registered acceptable gains as the economy stabilized, stocks of some bigger banks lagged. The combination of continued hefty loan losses at those larger institutions and the prospect of regulatory reform that could limit banks’ future activities restrained performance. Insurance company stocks also had less-than-stellar returns, in part because of concerns in the market over investment losses in their portfolios.

Information technology stocks, also about 30% of the fund’s assets, on average, during the half-year, did well almost across the board. Although tech stocks were battered as the recession raged and corporate buyers slashed spending on computers and other technology investments, that trend has now reversed. Companies that

had tightened their belts seem likely to begin upgrading equipment and software, a shift that has boosted the outlook for the tech sector. The pickup of the overall economy also gave a shot in the arm to consumer discretionary stocks, particularly specialty retailers, and even stocks of hotels, resorts, and cruise lines. While few would foresee a return to the “go-go” consumer spending that propelled the economy a few years ago, indicators that consumers are opening their wallets a bit more buoyed the sector’s stocks.

The fund’s health care stocks also turned in performances that outstripped that of the overall market. In late March, President Obama signed an overhaul of the U.S. health care system into law, but investors seem to have already concluded that reform is unlikely to damage the prospects of most companies in the industry, a factor that bolstered returns for those stocks.

Real-world lessons in the value of balance and perspective
The six months ended February 28, 2010, marked a continuation of the stock market rally that has been under way since March 2009. The nearly 12-month rebound is a welcome reprieve from the previous two years, when just about all equity investors, including shareholders in the FTSE Social Index Fund, endured painful losses.

The lessons of that punishing period and of the recent recovery serve as a reminder—albeit a potentially harsh one—of the importance of maintaining a long-term outlook on investing. Investors who panicked during the market declines of 2008 and early 2009 and sold their stock portfolios missed the robust returns of the last 12 months. Trying to time the up and down movements of the market can be a dangerous and money-losing strategy.

As the economy shows signs of solid recovery, investors are clearly more optimistic. But even if market performance is less volatile in the near term, there are certain to be periods of strong returns followed by painful retreats. That’s why, as always, investors need to focus on building a well-diversified portfolio of stock, bond, and money market holdings that matches their investing goals and time horizon. Such an approach puts you in a position to participate in the stock market’s long-term potential for growth, while providing some protection from its inevitable periods of decline.

The FTSE Social Index Fund can be an important component of such a long-term portfolio. In particular, for investors who prefer to invest in companies that meet strict social and environmental standards, the fund can form a key element of a socially conscious investment strategy that also keeps costs in check.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

FTSE Social Index Fund

Notes to Financial Statements

Vanguard FTSE Social 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: 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 investors who meet certain administrative and service criteria and invest a minimum amount of $5 million.

Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2006–2009), and for the period ended February 28, 201 0, and has concluded that no prov ision for federal income tax is required in the fund’s financ ial statements.

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

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

5. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

FTSE Social Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $84,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.03% of

Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

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

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, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

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

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, 2009, the fund had available capital loss carryforwards totaling $25,902,000 to offset future net capital gains of $79,000 through August 31, 2012, $985,000 through August 31, 2013, $367,000 through A ugust 31, 2014, $2,136,000 through August 31, 2016, and $22,335,000 through August 31, 2017. In addition, the fund realized losses of $66,197,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital loss es for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $414,730,000. Net unrealized appreciation of investment securities for tax purposes was $23,442,000, consisting of unrealized gains of $64,665,000 on securities that had risen in value since their purchase and $41,223,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $133,521,000 of investment securities and sold $141,649,000 of investment securities, other than temporary cash investments.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
FTSE Social Index Fund	8/31/2009	2/28/2010	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,090.23	$1.50
Institutional Shares	1,000.00	1,091.39	0.83
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.36	$1.45
Institutional Shares	1,000.00	1,024.00	0.80

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.29% for Investor Shares and 0.16% for Institutional Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Glossary

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

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

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

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

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.

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

Chairman’s Letter

Dear Shareholder,

For the six months ended February 28, 2010, the broad U.S. stock market returned about 10%. The market rallied through most of the period, while surrendering some gains in January.

All ten Vanguard U.S. Sector Index Funds recorded positive returns for the fiscal period. The consumer discretionary and industrial sectors set the pace, while the telecommunications, financial, and utilities sectors trailed the field.

An index fund measures its success by how closely it matches its target index, regardless of market conditions. Vanguard Quantitative Equity Group, the sector funds’ advisor, tightly tracked the funds’ target indexes in all sectors except for energy and telecommunication services. As we have noted in previous letters, SEC and IRS regulations limit the percentage of a fund’s assets that can be invested in a single stock, sometimes preventing the advisor from duplicating the construction of the target index. When the performance of a stock that is heavily weighted in an index diverges significantly from those of other stocks in the target index, a less-concentrated sector fund may not be able to track the index’s performance, a potential point of confusion for investors evaluating a fund’s return.

At the close of business on February 26, 2010, the final business day of the fiscal period, Vanguard changed the target benchmarks for all ten U.S. Sector Index Funds to address the gaps between the sector indexes’ composition and what Internal Revenue Code regulations allow a real-world fund to hold. The change—to the MSCI 25/50 Indexes—will provide shareholders with a more reasonable standard for evaluating their funds’ index-tracking success, while ensuring that the funds remain compliant with SEC and IRS regulations for favorable tax treatment.

Stock markets caught their breath at the end of a solid six months
For the six months, the broad U.S. stock market returned about 10%. The rally seemed to downshift toward the end of the period, as the investor relief that powered markets higher a year ago gave way to sober-minded assessment of corporate earnings-growth prospects.

International stocks produced more modest returns. In Europe, the precarious financial health of Greece and that of smaller economies such as Portugal and Ireland weighed on the markets. In Asia, the Japanese stock market’s weakness held back results for Asia Pacific indexes. Emerging markets stocks continued to outpace those from developed markets.

The broad taxable bond market returned 3.19%, with notable strength in corporate bonds. The broad municipal bond market returned 4.13%.

Consumer discretionary leads productive pack
The broad U.S. stock market continued its climb through the first six months of the fiscal year, although it didn’t maintain the torrid pace set through the spring and summer of 2009. All sectors of the stock market managed positive returns over the six months. Compared to other time periods, there was not a great difference between the best and worst performers.

With a return of more than 17%, the Consumer Discretionary Index Fund was the top Vanguard U.S. Sector Index Fund for the period. A wide variety of companies drove the gains. Media firms, specialty retailers, Internet retailers, hotels, restaurants, and automobile companies were among the businesses that rebounded as cost-cutting measures improved the bottom line and consumer spending increased.

The Industrials Index Fund was the second-highest performer, advancing more than 15%. Manufacturers and farms revved up production in the improving economy. The aerospace and defense and machinery subsectors both shone. Industrial conglomerate General Electric, a bellwether stock for the broader economy, saw improvement in service orders and equipment orders.

Five of the sector index funds––Energy, Materials, Health Care, Information Technology, and Consumer Staples––posted returns of between 10% and 12%, in line with the broad U.S. stock market. Boosts in the returns of oil stocks and of metals and mining stocks lifted the energy and materials sectors, respectively. The health care sector benefited from merger activity. Consumers’ renewed spending on computers and electronic components sparked the IT sector, while major household product and beverage companies were leaders in consumer staples.

The Telecommunication Services Index Fund returned more than 6%. This was several percentage points better than its benchmark, because of regulatory constraints that limited the fund’s exposure to the poorly performing stocks of AT&T and Verizon, both heavily weighted in the index. With the introduction of the new indexes, we don’t expect such return discrepancies to persist in the future. The Financials Index Fund returned about 2% as several major banks still struggled with distressed assets. The Utilities Index Fund, which invests in one of the smaller market sectors, also rose about 2%.

Sector funds offer means to diversify
Diversification, as we often remind investors, is an important element in any investing strategy––a point underscored by the stock and bond markets’ turbulence of the last two years. A portfolio that is diversified and balanced both across and within asset classes can help you tap the market’s top-performing assets while softening the blows from the worst performers.

Any one of the Vanguard U.S. Sector Index Funds, as a solitary investment, would likely be riskier and more unpredictable than the overall U.S. stock market. However, these funds are intended to complement and diversify an investment portfolio, rather than stand as a core holding.

Our commitment to indexing and to low costs, two other Vanguard precepts, is reflected in the U.S. Sector Index Funds. Vanguard Quantitative Equity Group, the funds’ advisor, is a proven global leader in its more than 30 years of expert index fund management. And the funds’ low costs allow you keep more of the returns.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III

Consumer Discretionary Index Fund

Notes to Financial Statements

Vanguard Consumer Discretionary 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, Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $40,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.02% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Consumer Discretionary Index Fund

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2009, the fund had available capital loss carryforwards totaling $6,383,000 to offset future net capital gains of $36,000 through August 31, 2013, $86,000 through August 31, 2014, $178,000 through August 31, 2015, $1,526,000 through August 31, 2016, and $4,557,000 through August 31, 2017. In addition, the fund realized losses of $7,145,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $223,460,000. Net unrealized depreciation of investment securities for tax purposes was $7,324,000, consisting of unrealized gains of $13,963,000 on securities that had risen in value since their purchase and $21,287,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $53,366,000 of investment securities and sold $6,748,000 of investment securities, other than temporary cash investments.

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

Consumer Staples Index Fund

Notes to Financial Statements

Vanguard Consumer Staples 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, Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $122,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.05% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Consumer Staples Index Fund

During the six months ended February 28, 2010, the fund realized $5,842,000 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, 2009, the fund had available capital loss carryforwards totaling $5,981,000 to offset future net capital gains of $276,000 through August 31, 2014, $773,000 through August 31, 2015, $2,261,000 through August 31, 2016, and $2,671,000 through August 31, 2017. In addition, the fund realized losses of $10,379,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $619,424,000. Net unrealized appreciation of investment securities for tax purposes was $1,855,000, consisting of unrealized gains of $27,502,000 on securities that had risen in value since their purchase and $25,647,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $71,667,000 of investment securities and sold $84,827,000 of investment securities, other than temporary cash investments.

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

Energy Index Fund

Notes to Financial Statements

Vanguard Energy 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, Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $229,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.09% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Energy Index Fund

During the six months ended February 28, 2010, the fund realized $16,377,000 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, 2009, the fund had available capital loss carryforwards totaling $24,215,000 to offset future net capital gains of $5,000 through August 31, 2013, $789,000 through August 31, 2014, $461,000 through August 31, 2015, $1,694,000 through August 31, 2016, and $21,266,000 through August 31, 2017. In addition, the fund realized losses of $62,562,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $1,124,964,000. Net unrealized appreciation of investment securities for tax purposes was $49,753,000, consisting of unrealized gains of $108,879,000 on securities that had risen in value since their purchase and $59,126,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $270,943,000 of investment securities and sold $167,604,000 of investment securities, other than temporary cash investments.

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

Financials Index Fund

Notes to Financial Statements

Vanguard Financials 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, Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $112,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.04% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. The fund’s custodian bank has agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the six months ended February 28, 2010, custodian fee offset arrangements reduced the fund’s expenses by $5,000 (an annual rate of 0.00% of average net assets).

Financials Index Fund

D. 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.

At February 28, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

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

During the six months ended February 28, 2010, the fund realized $27,196,000 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, 2009, the fund had available capital loss carryforwards totaling $30,027,000 to offset future net capital gains of $85,000 through August 31, 2014, $11,000 through August 31, 2015, $1,313,000 through August 31, 2016, and $28,618,000 through August 31, 2017. In addition, the fund realized losses of $118,026,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $762,327,000. Net unrealized depreciation of investment securities for tax purposes was $217,596,000, consisting of unrealized gains of $4,550,000 on securities that had risen in value since their purchase and $222,146,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2010, the fund purchased $69,538,000 of investment securities and sold $186,528,000 of investment securities, other than temporary cash investments.

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

Health Care Index Fund

Notes to Financial Statements

Vanguard Health Care 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: Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $145,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.06% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Health Care Index Fund

During the six months ended February 28, 2010, the fund realized $8,459,000 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, 2009, the fund had available capital loss carryforwards totaling $10,937,000 to offset future net capital gains of $207,000 through August 31, 2014, $343,000 through August 31, 2015, $3,126,000 through August 31, 2016, and $7,261,000 through August 31, 2017. In addition, the fund realized losses of $10,493,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $782,256,000. Net unrealized depreciation of investment securities for tax purposes was $62,702,000, consisting of unrealized gains of $35,821,000 on securities that had risen in value since their purchase and $98,523,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $97,376,000 of investment securities and sold $105,247,000 of investment securities, other than temporary cash investments.

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

Industrials Index Fund

Notes to Financial Statements

Vanguard Industrials 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: Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $54,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.02% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. The fund’s custodian bank has agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the six months ended February 28, 2010, custodian fee offset arrangements reduced the fund’s expenses by $2,000 (an annual rate of 0.00% of average net assets).

Industrials Index Fund

At February 28, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended February 28, 2010, the fund realized $10,198,000 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, 2009, the fund had available capital loss carryforwards totaling $5,549,000 to offset future net capital gains of $18,000 through August 31, 2014, $283,000 through August 31, 2015, $552,000 through August 31, 2016, and $4,696,000 through August 31, 2017. In addition, the fund realized losses of $11,763,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $359,075,000. Net unrealized depreciation of investment securities for tax purposes was $71,272,000, consisting of unrealized gains of $2,390,000 on securities that had risen in value since their purchase and $73,662,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2010, the fund purchased $173,406,000 of investment securities and sold $113,370,000 of investment securities, other than temporary cash investments.

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

Information Technology Index Fund

Notes to Financial Statements

Vanguard Information Technology 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, Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

5. Other: Dividend income is recorded on the ex-dividend date. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. Fees assessed on redemptions of capital shares are credited to paid-in capital.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $204,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.08% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Information Technology Index Fund

During the six months ended February 28, 2010, the fund realized $12,044,000 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, 2009, the fund had available capital loss carryforwards totaling $15,094,000 to offset future net capital gains of $63,000 through August 31, 2013, $188,000 through August 31, 2014, $612,000 through August 31, 2015, $218,000 through August 31, 2016, and $14,013,000 through August 31, 2017. In addition, the fund realized losses of $20,087,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $1,055,751,000. Net unrealized appreciation of investment securities for tax purposes was $15,481,000, consisting of unrealized gains of $75,042,000 on securities that had risen in value since their purchase and $59,561,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $409,167,000 of investment securities and sold $77,385,000 of investment securities, other than temporary cash investments.

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

Materials Index Fund

Notes to Financial Statements

Vanguard Materials 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, Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $110,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.04% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. The fund’s custodian bank has agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the six months ended February 28, 2010, custodian fee offset arrangements reduced the fund’s expenses by $2,000 (an annual rate of 0.00% of average net assets).

Materials Index Fund

During the six months ended February 28, 2010, the fund realized $11,773,000 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, 2009, the fund had available capital loss carryforwards totaling $14,998,000 to offset future net capital gains of $6,000 through August 31, 2014, $698,000 through August 31, 2015, $1,458,000 through August 31, 2016, and $12,836,000 through August 31, 2017. In addition, the fund realized losses of $20,530,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $633,909,000. Net unrealized depreciation of investment securities for tax purposes was $55,813,000, consisting of unrealized gains of $22,792,000 on securities that had risen in value since their purchase and $78,605,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2010, the fund purchased $122,777,000 of investment securities and sold $51,922,000 of investment securities, other than temporary cash investments.

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

Telecommunication Services Index Fund

Notes to Financial Statements

Vanguard Telecommunication Services 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: Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $41,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.02% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Telecommunication Services Index Fund

The following table summarizes the fund’s investments as of February 28, 2010, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	202,222	136	—

During the six months ended February 28, 2010, the fund realized $1,137,000 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, 2009, the fund had available capital loss carryforwards totaling $23,697,000 to offset future net capital gains of $29,000 through August 31, 2014, $818,000 through August 31, 2015, $4,154,000 through August 31, 2016, and $18,696,000 through August 31, 2017. In addition, the fund realized losses of $22,599,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $224,174,000. Net unrealized depreciation of investment securities for tax purposes was $21,816,000, consisting of unrealized gains of $13,574,000 on securities that had risen in value since their purchase and $35,390,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $72,948,000 of investment securities and sold $37,555,000 of investment securities, other than temporary cash investments.

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

Utilities Index Fund

Notes to Financial Statements

Vanguard Utilities 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: Admiral Shares and ETF Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2006–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

4. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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. Fees assessed on redemptions of capital shares are credited to paid-in capital.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $120,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.05% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. The fund’s custodian bank has agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the six months ended February 28, 2010, custodian fee offset arrangements reduced the fund’s expenses by $1,000 (an annual rate of 0.00% of average net assets).

Utilities Index Fund

During the six months ended February 28, 2010, the fund realized $4,374,000 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, 2009, the fund had available capital loss carryforwards totaling $3,425,000 to offset future net capital gains of $515,000 through August 31, 2015, and $2,910,000 through August 31, 2017. In addition, the fund realized losses of $14,092,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At February 28, 2010, the cost of investment securities for tax purposes was $701,401,000. Net unrealized depreciation of investment securities for tax purposes was $115,134,000, consisting of unrealized gains of $2,480,000 on securities that had risen in value since their purchase and $117,614,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2010, the fund purchased $190,287,000 of investment securities and sold $43,315,000 of investment securities, other than temporary cash investments.

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

About Your Fund’s Expenses

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The examples on this page 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 acompanying table illustrates your fund’s costs in two ways:

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

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

The calculations 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 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.

1 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 0.26% for the Consumer Discretionary Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Consumer Staples Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Energy Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Financials Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Health Care Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Industrials Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Information Technology Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Materials Index Fund Admiral Shares and 0.23% for the ETF Shares; 0.26% for the Tele communication Services Index Fund Admiral Shares and 0.23% for the ETF Shares; and 0.26% for the Utilities Index Fund Admiral Shares and 0.23% for the 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, the most recent 12-month period, then divided by the number of days in the most recent 12-month period.

Glossary

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 below). 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.

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

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

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

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

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.

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

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 (in the case of bonds) 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.

> For the fiscal half-year ended February 28, 2010, Vanguard Extended Duration Treasury Index Fund returned about –8%. The market return of the ETF Shares was a bit lower.

> Yields of long-term Treasury securities rose during the period in response to investors’ expectations of higher inflation and rising interest rates.

Chairman’s Letter

Dear Shareholder,

Vanguard Extended Duration Treasury Index Fund returned about –8% for the half-year through February 2010, a not unusual swing from the positive 12-month return we reported to you last fall. This is because of the fund’s long duration, which makes its share price very sensitive to changes in interest rates.

During the past six months, investors have modestly ratcheted up their long-term inflation forecasts, and this change is reflected in increases in long-term interest rates. They’ve done so because the economy appears to be emerging from the worst recession in a generation, and the later stages of expansions can be inflationary. For the near term, the market is also concerned about the potential consequences of government policies that were aimed at combating the economic slump and an unprecedented financial crisis.

The fund’s performance slightly trailed that of its benchmark, the Barclays Capital U.S. Treasury STRIPS 20–30 Year Equal Par Bond Index. Small short-term deviations, positive or negative, aren’t unusual because of the cost-efficient sampling technique the fund uses and because of slight differences in the way the index and the fund are priced at the close of the trading day.

The Fed begins unwinding its rescue programs
The yields of longer-term U.S. Treasury bonds rose during the past six months. Thirty-year Treasury yields rose the most,

to 4.53%, an increase of 35 basis points for the half year (and 82 basis points over 12 months). By contrast, the yields of the shortest-term securities remained near 0%.

Although the Federal Reserve Board expects to keep its target for short-term interest rates close to zero for “an extended period,” it began to wind down credit programs established during the financial crisis. The Fed’s most dramatic (though largely symbolic) act was to raise the interest rate at its discount window, a lending facility designed to help commercial banks and other depository institutions meet emergency short-term funding needs.

The broad taxable bond market returned 3.19%, with notable strength in corporate bonds. The broad municipal bond market returned 4.13%.

Stock markets caught their breath at the end of a solid six months
For the six months, the broad U.S. stock market returned about 10%. The rally seemed to downshift toward the end of the period, as the investor relief that powered markets higher a year ago gave way to sober-minded assessment of corporate earnings-growth prospects.

Smaller-capitalization stocks did a little better than larger-caps, and growth-oriented securities bested their value-

oriented counterparts, but the uniformity of returns from different market segments was more striking than the differences.

International stocks produced more modest returns. In Europe, the precarious financial health of Greece and smaller economies such as Portugal and Ireland weighed on the markets. In Asia, the Japanese stock market’s weakness held back results for Asia Pacific indexes. Emerging market stocks continued to outpace those from developed markets.

The market’s inflation forecast put pressure on the fund’s yield
In our last shareholder letter, we reported that Vanguard Extended Duration Treasury Index Fund returned about 8% for the fiscal year ended August 31, 2009. In a bit of negative symmetry, the fund returned about –8% for the recent fiscal half-year.

This fund’s returns are particularly volatile because of its long duration—about 26.5 years at the end of February. The prices of the fund’s securities can rise or fall dramatically as investors grapple with the higher-than-usual uncertainty associated with the longest-maturity bonds.

Much of the extra uncertainty surrounds expectations about inflation, an ever-present concern of long-term bondholders. The financial market’s consensus estimate of the 10-year future inflation rate has shifted since last August from 1.65% annually to 2.16% annually, as of February. (The consensus estimate figures are

derived from the “break-even inflation rate,” which compares the expected yield of traditional Treasury bonds with that of Treasury inflation-protected securities.)

Investors are apprehensive about the potential inflationary pressure arising from the economy’s apparent emergence from the Great Recession. Continued expansion could stoke inflation, although probably not too soon because of factors such as still-low capacity utilization and a high jobless rate.

The federal government’s large debt-financing needs, which have expanded greatly because of its stimulus programs, are another source of concern. Large issuance of new Treasury bonds can put upward pressure on yields as it drives down bond prices.

To address these potentially inflationary developments, the Federal Reserve Board undoubtedly will at some point rein in its highly accommodative monetary policy. This too could put upward pressure on yields.

The fund can be a useful tool for liability-driven investing
Perhaps counterintuitively, the loss incurred by the Extended Duration Treasury Index Fund during the fiscal half-year shows that the fund performed as intended. The fund was designed primarily to help managers of defined-benefit pension plans hedge changes in the value of their future liabilities with an investment that moves in the same direction. For pension-plan managers, the fund can serve as a straightforward and transparent tool to help reduce the volatility in the ratio of a plan’s assets to its liabilities.

Thank you for entrusting your assets to Vanguard.

Sincerely,

Security Valuation: Bonds, and 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. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Securities for which market quotations are not readily available, or whose values have been affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2008–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

4. Other: 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. Fees, if any, assessed on purchases of Institutional Shares are credited to paid-in capital.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $53,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.02% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Extended Duration Treasury Index Fund	8/31/2009	2/28/2010	Period¹
Based on Actual Fund Return
Institutional Shares	$1,000.00	$915.81	$0.52
ETF Shares	1,000.00	915.72	0.62
Based on Hypothetical 5% Yearly Return
Institutional Shares	$1,000.00	$1,024.25	$0.55
ETF Shares	1,000.00	1,024.15	0.65

1 The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.11% for Institutional Shares and 0.13% 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

Average Coupon. The average interest rate paid on the fixed income securities held by a fund. It is expressed as a percentage of face value.

Average Duration. An estimate of how much the value of the bonds held by a fund will fluctuate in response to a change in interest rates. To see how the value could change, multiply the average duration by the change in rates. If interest rates rise by 1 percentage point, the value of the bonds in a fund with an average duration of five years would decline by about 5%. If rates decrease by a percentage point, the value would rise by 5%.

Average Effective Maturity. The average length of time until fixed income securities held by a fund reach maturity and are repaid, taking into consideration the possibility that the issuer may call the bond before its maturity date. The figure reflects the proportion of fund assets represented by each security; it also reflects any futures contracts held. In general, the longer the average effective maturity, the more a fund’s share price will fluctuate in response to changes in market interest rates.

Average Quality. An indicator of credit risk, this figure is the average of the ratings assigned to a fund’s fixed income holdings by credit-rating agencies. The agencies make their judgment after appraising an issuer’s ability to meet its obligations. Quality is graded on a scale, with Aaa or AAA indicating the most creditworthy bond issuers. U.S. Treasury securities are considered to have the highest credit quality.

Distribution by Coupon. A breakdown of the securities in a fund according to coupon rate—the interest rate that an issuer promises to pay, expressed as an annual percentage of face value. Securities with unusually high coupon rates may be subject to call risk, the possibility that they will be redeemed (or “called”) early by the issuer.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

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

Yield to Maturity. The rate of return an investor would receive if the fixed income securities held by a fund were held to their maturity dates.

Chairman’s Letter

Dear Shareholder,

For the six months ended February 28, 2010, the Vanguard Mega Cap 300 Index Funds successfully tracked their target indexes. With a return of about 11%, the Mega Cap 300 Growth Index Fund led the three. The Mega Cap 300 Value Index Fund returned more than 6%, and the Mega Cap 300 Index Fund—essentially a combination of the two other portfolios—returned more than 8%.

The Value Fund lagged its peer group’s average return, while the two other funds ended a bit ahead of their respective peer averages.

Stock markets caught their breath at the end of a solid six months
For the six months, the broad U.S. stock market returned about 10%. The rally seemed to downshift toward the end of the period, as the investor relief that powered markets higher a year ago gave way to sober-minded assessment of corporate earnings-growth prospects.

International stocks produced more modest returns. In Europe, the precarious financial health of Greece and that of smaller economies such as Portugal and Ireland weighed on the markets. In Asia,

the Japanese stock market’s weakness held back results for Asia Pacific indexes. Emerging market stocks continued to outpace those from developed markets.

The broad taxable bond market returned 3.19%, with notable strength in corporate bonds. The broad municipal bond market returned 4.13%.

Mega-caps joined the rebound, with notable strength in tech
Vanguard’s three Mega Cap 300 Index Funds are designed for shareholders looking to invest in the U.S. market’s largest stocks as a whole or in portfolios made up of either the growth or value components of that group. During the past six months, the market’s largest stocks trailed their smaller counterparts.

The Mega Cap 300 Index Fund posted a solid six-month return thanks to continued stock gains driven by confidence in a turnaround in the global economy. The fund benefited from its heavy weighting in information technology stocks, which performed well owing to investors’ expectations of a pickup in corporate spending on technology infrastructure.

In addition, the fund got a boost from double-digit gains posted by industrial and consumer discretionary stocks. The sizable financial sector was a relatively weak area.

Reflecting investors’ general preference for growth stocks during the period, the Mega Cap 300 Growth Index Fund was the best performer of the three, with its gain outstripping that of the broad stock market. More than one-third of the fund’s assets were in information technology stocks, most of them strong performers. Also boosting returns was the stellar performance of consumer discretionary, energy, and industrial stocks, all of which benefited from mounting evidence of a solid economic recovery.

The Mega Cap 300 Value Index Fund lagged the other two funds in part because of the relative weakness of the financial sector. The banks, brokerages, and other financial services companies in this sector made up nearly one quarter of the Value Fund’s assets, on average. Although there were some bright spots (including regional banks), the stocks of insurance companies and some big banks underperformed owing to continued fallout from the recession and the financial crisis.


Expense Ratios
Your Fund Compared With Its Peer Group

	Institutional	ETF	Peer Group
	Shares	Shares	Average
Mega Cap 300 Index Fund	0.11%	0.13%	1.27%
Mega Cap 300 Growth Index Fund	0.11	0.13	1.37
Mega Cap 300 Value Index Fund	0.11	0.13	1.28

The fund expense ratios shown are from the prospectuses dated December 28, 2009, and represent estimated costs for the current fiscal year based on the funds’ net assets as of the prospectus date. For the six months ended February 28, 2010, the annualized expense ratios were: for the Mega Cap 300 Index Fund, 0.11% for Institutional Shares and 0.13% for ETF Shares; for the Mega Cap 300 Growth Index Fund, 0.11% for Institutional Shares and 0.13% for ETF Shares; and for the Mega Cap 300 Value Index Fund, 0.11% for Institutional Shares and 0.13% for ETF Shares. Peer-group expense ratios are derived from data provided by Lipper Inc. and capture information through year-end 2009.

Peer groups: for the Mega Cap 300 Index Fund, Large-Cap Core Funds; for the Mega Cap 300 Growth Index Fund, Large-Cap Growth Funds; and for the Mega Cap 300 Value Index Fund, Large-Cap Value Funds.

Energy stocks, the Value Fund’s second-largest sector, also restrained performance. Oil and gas exploration and production stocks did well as crude oil prices climbed, but the overall sector return was restrained by the fund’s heavy weighting in integrated oil and gas stocks, which underperformed partly as a result of concerns about profit pressures in their refining operations. These headwinds were somewhat offset by strength in industrial and consumer discretionary stocks.

A period of extremes underscores the benefits of balance
The six months ended February 28 were marked by the continuation of the stock market rally that began in March 2009. This rally has been especially welcome for its contrast with the preceding two years, which produced deep and painful losses for many investors. That was particularly true for shareholders in the three Mega Cap 300 Index Funds, which were launched just after the financial turbulence began.

For all investors, the volatility of the past several years serves as a stark reminder of the value of maintaining a diversified portfolio of stocks, bonds, and money market funds. Staying firmly on that course allowed investors to participate in the robust stock rally of the past year.

While there are ample signs that a global economic recovery has taken root, this does not mean that investors can expect a smooth ride going forward. Even if the markets avoid the kind of extreme swings we saw in the past several years, investors need to be prepared for inevitable ups and downs. The Mega Cap 300 Index Funds, which provide exposure to the largest stocks in the U.S. market at extremely low cost, can be useful tools for investors navigating these choppy waters.

Thank you for investing your assets with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Mega Cap 300 Index Fund

Notes to Financial Statements

Vanguard Mega Cap 300 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 and service criteria and invest a minimum amount of $5 million. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2008–2009), and for the period ended February 28, 2010, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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.

Mega Cap 300 Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $62,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.02% of

Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At February 28, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended February 28, 2010, the fund realized $7,849,000 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, 2009, the fund had available capital loss carryforwards totaling $948,000 to offset future net capital gains through August 31, 2017. In addition, the fund realized losses of $13,472,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2010, the cost of investment securities for tax purposes was $332,124,000. Net unrealized depreciation of investment securities for tax purposes was $9,524,000, consisting of unrealized gains of $16,345,000 on securities that had risen in value since their purchase and $25,869,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2010, the fund purchased $61,240,000 of investmen securities and sold $61,000,000 of investment securities, other than temporary cash investments.

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

Net Increase (Decrease)—ETF Shares	9,118	200	118,353	3,600

The amount of Institutional Shares issued during the year ended August 31, 2009, includes $58,176,000 in purchases that were processed late and should have been recorded in the prior fiscal period. Vanguard, as transfer agent for the fund, offset any impact to the fund resulting from late processing of shareholder transactions. Accordingly, the purchases had no impact to t he fund’s net asset value per share or total returns.

G. In preparing the financial statements as of February 28, 2010, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

Mega Cap 300 Growth Index Fund

Notes to Financial Statements

Vanguard Mega Cap 300 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 and service criteria and invest a minimum amount of $5 million. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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, 2008–2009), and for the period ended February 28, 201 0, and has concluded that no prov ision for federal income tax is required in the fund’s financ ial statements.

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

Mega Cap 300 Growth Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $74,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.03% of

Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At February 28, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended February 28, 2010, the fund realized $54,843,000 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, 2009, the fund had available capital loss carryforwards totaling $7,258,000 to offset future net capital gains through August 31, 2017. In addition, the fund realized losses of $25,649,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2010, the cost of investment securities for tax purposes was $358,120,000. Net unrealized appreciation of investment securities for tax purposes was $16,891,000, consisting of unrealized gains of $29,203,000 on securities that had risen in value since their purchase and $12,312,000 in unrealized losses on securities that had fallen in value since their purchase.

Mega Cap 300 Growth Index Fund

E. During the six months ended February 28, 2010, the fund purchased $98,789,000 of investment securities and sold $371,604,000 of investment securities, other than temporary cash investments.

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


	Six Months Ended			Year Ended

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

Net Increase (Decrease)—ETF Shares	(272,554)	(6,900)	397,215	10,800

The amounts of Institutional Shares issued during the year ended August 31, 2009, are negative because they reflect the cancellation of $58,176,000 of purchases recorded during the prior fiscal period that were determined to have been processed incorrectly. Vanguard, as a transfer agent for the fund, offset any impact to the fund resulting from incorrectly processed shareholder transactions. Accordingly, the cancelled purchases had no impact to the fund’s net asset values per share or total return s.

G. In preparing the financial statements as of February 28, 2010, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

Mega Cap 300 Value Index Fund

Notes to Financial Statements

Vanguard Mega Cap 300 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 and service criteria and invest a minimum amount of $5 million. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for

U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

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, 2008–2009), and for the period ended February 28, 201 0, and has concluded that no prov ision for federal income tax is required in the fund’s financ ial statements.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At February 28, 2010, the fund had contributed capital of $54,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.02% of

Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. The fund’s custodian bank has agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the six months ended February 28, 2010, custodian fee offset arrangements reduced the fund’s expenses by $2,000 (an annual rate of 0.00% of average net assets).

At February 28, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended February 28, 2010, the fund realized $4,496,000 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, 2009, the fund had available capital loss carryforwards totaling $851,000 to offset future net capital gains through August 31, 2017. In addition, the fund realized losses of $19,616,000 during the period from November 1, 2008, through August 31, 2009, which are deferred and will be treated as realized for tax purposes in fiscal 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2010; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2010, the cost of investment securities for tax purposes was $271,518,000. Net unrealized appreciation of investment securities for tax purposes was $1,559,000, consisting of unrealized gains of $19,947,000 on securities that had risen in value since their purchase and $18,388,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2010, the fund purchased $82,610,000 of investment securities and sold $54,587,000 of investment securities, other than temporary cash investments.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	8/31/2009	2/28/2010	Period
Based on Actual Fund Return

Mega Cap 300 Value Index Fund
Institutional Shares	$1,000.00	$1,066.82	$0.56
ETF Shares	1,000.00	1,066.85	0.67
Based on Hypothetical 5% Yearly Return
Mega Cap 300 Index Fund
Institutional Shares	$1,000.00	$1,024.25	$0.55
ETF Shares	1,000.00	1,024.15	0.65
Mega Cap 300 Growth Index Fund
Institutional Shares	$1,000.00	$1,024.25	$0.55
ETF Shares	1,000.00	1,024.15	0.65
Mega Cap 300 Value Index Fund
Institutional Shares	$1,000.00	$1,024.25	$0.55
ETF Shares	1,000.00	1,024.15	0.65

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 Mega Cap 300 Index Fund, 0.11% for Institutional Shares and 0.13% for ETF Shares; for the Mega Cap 300 Growth Index Fund, 0.11% for Institutional Shares and 0.13% for ETF Shares; and for the Mega Cap 300 Value Index Fund, 0.11% for Institutional Shares and 0.13% 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.
