President’s Letter

Dear Shareholder,

Vanguard U.S. Growth Fund’s Investor Shares returned a disappointing –7.4% for the fiscal year ended August 31, 2008. The lower-cost Admiral Shares returned –7.3%. After a subpar first half, the fund’s performance versus its peers significantly improved in the second half—with gains that brought it in line with the peer group but left it behind the benchmark Russell 1000 Growth Index for the 12 months.

If you hold shares of the U.S. Growth Fund in a taxable account, you may wish to refer to our report on after-tax performance on page 25.

Stocks performed poorly as volatility returned

Stocks lost ground as credit-market turmoil spread throughout the global economy. Over the full 12 months, the broad U.S. stock market lost about –10% of its value. International markets followed a similar path, returning about –12% for the year.

The descent was bumpy. After years of relative calm, the U.S. market routinely rose or fell by more than a percentage point in a day’s trading. The volatility reflected a seemingly endless series of unnerving developments: persistently high energy prices, further deterioration in the housing market, several bank failures, and the broad economy’s deceleration.

Risk-aversion increased, and Treasuries outperformed

The collapse in subprime mortgage-backed securities and the aftershocks prompted a flight to safety. Short-term U.S. Treasury securities were among the fixed income market’s best performers. Over the 12 months, the broad taxable bond market returned a respectable 5.9%, largely reflecting the Treasury bond rally.

As risk-aversion increased, the difference between the yields of Treasury bonds and those of all other securities increased, depressing the price of corporate debt. (As you know, yield and price move in opposite directions.) Even as corporate bonds grew cheaper, the prices of most goods and services rose quickly, powered by escalating energy prices.

The combination of higher inflation, financial market volatility, and economic weakness put the U.S. Federal Reserve Board in an uncomfortable position. The Fed decided that it was imperative to respond to the financial crisis with a dramatic easing of monetary policy through interest rate cuts, even as it recognized that the result might be even higher inflation. Over the full 12 months, the Fed reduced its target for the federal funds rate from 5.25% to 2.00%.

Stock selection delivered mixed results for the fund

Stocks began the fiscal year with a flourish: Most markets reached record highs in October 2007. But as anxious investors grappled with trouble in the credit markets and heightened economic

uncertainty, equities finished the 12 months broadly lower. All but three of the ten industry sectors in the U.S. Growth Fund’s benchmark index declined in value, creating more hurdles for the fund.

The fund’s concentrated portfolio faced a tough test in this unsettled environment. Top-ten holdings represented about one-third of the fund’s average value, magnifying the impact of individual stocks. This was a plus in health care—the leading contributor to return and the fund’s second-largest sector, on average—where the advisors’ outsized commitment to biotechnology proved rewarding. Gilead Sciences, Genentech, and Celgene contributed a total of more than 2 percentage points to the fund’s return.

The materials sector was the best performer in both the market and the fund. However, it represented a small slice of the portfolio. And although oil prices dominated the year’s headlines—soaring to record highs before retreating in July and August—energy stocks made almost no contribution to performance for the year, in contrast to earlier robust returns.

On the downside, information technology and financial stocks collectively trimmed more than 7 percentage points from the fund’s return. The tech sector represented almost one-third of the portfolio’s average value (slightly more than in the benchmark), and suffered from budget curtailments in the face of growing concerns about a global economic slowdown. Semiconductor-product companies were hit especially

hard, including Broadcom, Intel, and NVIDIA. Among other notable detractors were two top-ten holdings: Google and Cisco Systems.

Financial services companies continued to be buffeted by asset write-downs and other challenges posed by the subprime-mortgage crisis that emerged more than a year ago. Amid widespread weakness, the fund’s leading detractors included investment bank Lehman Brothers Holdings, CME Group (the Chicago Mercantile Exchange), and multiline insurer American International Group (AIG). Bucking this trend was brokerage firm Charles Schwab, an outsized position that posted a double-digit gain.

Relative to the benchmark, the advisors’ overweighting of health care stocks added almost 3 percentage points to return. However, this performance advantage was more than offset by the commitments to the weakly performing information technology and financial stocks. Consumer staples stocks, often viewed as somewhat recession-proof, performed well in the benchmark, but the fund’s holdings turned in a generally weak performance.

For more details about the fund’s positioning and performance during the period, please see the Advisors’ Report, which begins on page 7. Also, please note that in July, two portfolio managers from AllianceBernstein—an advisor to the fund since 2001—were named to replace Alan Levi, who plans to retire.

A long-term view and quality focus are key

Overall, the last ten years have been challenging for growth-stock investors. After lagging for several years—notably during the bear market of 2000–2002—growth stocks reclaimed the lead from their value-oriented counterparts in mid-2007. But your advisors’ focus on high-quality companies has not been rewarded consistently. For the ten years ended August 31, the –1.5% annual return of U.S. Growth trailed that of its comparative standards, as shown in the table on page 4. Although these results have clearly been a disappointment, we remain confident that the advisors’ approach to large-cap growth investing has the potential to produce competitive long-term returns.

Although we can’t predict whether growth will lead value, or whether large-cap stocks will outperform small-caps, one thing is certain: The markets will continue to deliver surprises. That’s why we believe the key to investment success is to determine a diversified mix of stock, bond, and money market funds that is consistent with your goals, time horizon, and risk tolerance. Once you have established your asset allocation plan, try to stick with it. And always pay attention to costs.

The advisors of the U.S. Growth Fund make sizable commitments to a relatively small number of stocks (about 70–80), grounded in the advisors’ fundamental analysis and extensive research. That is why it’s appropriate to consider this fund for a complementary, rather than a cornerstone, role within a balanced portfolio.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III

President and Chief Executive Officer

Advisors’ Report

For the fiscal year ended August 31, 2008, the Investor Shares of Vanguard U.S. Growth Fund returned –7.4%, and the lower-cost Admiral Shares returned –7.3%. This performance reflects the combined efforts of your fund’s two independent advisors. The use of multiple advisors provides exposure to distinct, yet complementary, investment approaches, enhancing the fund’s diversification.

The advisors, the amount and percentage of fund assets each manages, and brief descriptions of their investment strategies are presented in the table below. Each advisor has also prepared a discussion of the investment environment that existed during the fiscal year and of how the portfolio’s positioning reflects this assessment. These comments were prepared on September 12, 2008.

and corporate profits proved satisfactory, if not better than expected, this masked significant and widening divergences. Escalating energy and commodity prices, exacerbated by a weakened U.S. dollar combined with stagnating employment growth, imposed an increasing burden on already stressed American consumers. The erosion of disposable personal income, consumption, and consumer confidence was compounded by protracted weakness in housing markets and equity values. Reflecting this environment, equity markets have become increasingly risk-averse.

In contrast to the U.S. economy’s moderating and subdued growth, a number of overseas economies experienced comparatively robust expansion, particularly those of several populous emerging markets. The combination of healthy growth in foreign demand and the weak U.S. dollar led to a resurgence of U.S. export growth and manufacturing, providing an important counterbalance to the weakness in domestic consumption. Reflecting this, overall U.S. exports increased 18% through the first six months of 2008, expanding 50% faster than China’s export sector. This environment has benefited a number of the holdings in our portion of the portfolio, given our focus on companies with leading, in some cases dominant, industry positions; many of these companies also enjoy a strong and increasing global presence.

Our performance was adversely affected by disappointing stock selection among a number of financial service and technology holdings, magnified by an overweighted exposure to financials early in the year. This was largely offset by strong stock selection among a number of the portfolio’s health care and industrials holdings, combined with our significant absolute and overweighted exposure to health care.

Our holdings generally continued to exhibit the fundamental strength we seek, with upward earnings revisions remaining more prevalent than among benchmark constituents. Although stocks of such companies failed to enjoy their historical rewards over this period, we believe that this anomaly is unlikely to persist. In particular, in a global economic and earnings slowdown, which we appear to be in, investors tend to more carefully distinguish among companies and favor those best-positioned to sustain their earnings growth. We would expect that this tendency will once again reward the kind of superior earnings potential that we emphasize.

William Blair & Company, L.L.C.

Portfolio Manager:

John F. Jostrand, CFA, Principal

U.S. equity markets were very difficult and volatile over the fiscal year, owing to economic uncertainty. Markets declined in response to the continued credit crisis;

deleveraging; and weakened consumers in the face of rising gas and food costs, increasing unemployment, tightening lending standards, and elevated levels of credit and mortgage delinquencies.

Investors’ concerns shifted from slowing U.S. economic growth to rising inflation, especially in commodity and food prices. Most notably, the price of oil surged to record levels as demand remained high, especially from emerging-market countries. Also, supply issues surfaced and investor speculation in oil rose as many looked to it as an inflationary hedge or an alternative to U.S. dollar investments or the risky credit markets. However, by the end of August, the price of oil retreated, which was a relief to the equity markets, as demand destruction occurred modestly and some weakness in global growth appeared.

Our portion of the portfolio benefited from our bias toward quality growth stocks, which typically do better when growth becomes harder to find. Health care was the highest-performing sector, with good stock selection in the biotechnology industry. The information technology sector was the largest detractor due to our slight overweighting in a weaker benchmark group, as well as our stock selection in the computer and peripherals industry.

Going forward, it’s difficult to predict what additional downside risks remain or when investor sentiment will turn. We believe that economic growth will continue to be subdued into 2009, as the financial system and consumers likely have a long workout period ahead.

In this environment, we have not adopted a particularly defensive posture. Instead, we continue to rely on our quality growth investment philosophy and process, seeking stocks with attractive long-term earnings growth prospects, strong financial positions, and competitive and sustainable business models that we believe will outperform over time. This approach generally leads us to companies that have somewhat more defensive characteristics during market conditions like those experienced recently, primarily because of the firms’ more stable business models with better balance sheets. In our view, quality growth opportunities remain readily available, and we are taking advantage of increasingly attractive valuation levels to buy stocks that we believe will produce superior long-term returns. Whether the markets experience elevated levels of volatility or a slow-growth environment, investors will continue to seek strong, quality companies, which become scarce, and thus more valuable, in a challenging period.

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.

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 values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

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

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 on federal income tax returns for all open tax years (tax years ended August 31, 2005–2008), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

5. 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.

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

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

B. 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 fee for AllianceBernstein L.P. is subject to quarterly adjustments based on performance for the preceding three years relative to the Russell 1000 Growth Index. The basic fee for William Blair & Company, L.L.C., is subject to quarterly adjustments based on performance since June 1, 2004, relative to the Russell 1000 Growth Index.

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

For the year ended August 31, 2008, the aggregate investment advisory fee represented an effective annual basic rate of 0.15% of the fund’s average net assets before a decrease of $1,572,000 (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 August 31, 2008, the fund had contributed capital of $407,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.41% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

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. The fund’s custodian bank has also agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the year ended August 31, 2008, these arrangements reduced the fund’s management and administrative expenses by $259,000 and custodian fees by $4,000. The total expense reduction represented an effective annual rate of 0.01% of the fund’s average net assets.

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.

For tax purposes, at August 31, 2008, the fund had $19,079,000 of ordinary income available for distribution. The fund had available realized losses of $6,142,272,000 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, and $123,651,000 through August 31, 2013.

At August 31, 2008, the cost of investment securities for tax purposes was $4,505,687,000. Net unrealized appreciation of investment securities for tax purposes was $265,942,000, consisting of unrealized gains of $436,726,000 on securities that had risen in value since their purchase and $170,784,000 in unrealized losses on securities that had fallen in value since their purchase.

At August 31, 2008, the aggregate settlement value of open futures contracts expiring in September 2008 and the related unrealized appreciation (depreciation) were:

			($000)
	Number of	Aggregate	Unrealized
	Long (Short)	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
S&P 500 Index	198	63,489	(3,612)
S&P Mid-Cap 400 Index	108	44,064	(3,123)
E-mini S&P 500 Index	20	1,283	7
E-mini S&P Mid-Cap 400 Index	6	489	15

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

F. During the year ended August 31, 2008, the fund purchased $5,357,366,000 of investment securities and sold $5,842,699,000 of investment securities other than temporary cash investments.

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

H. In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 157 (“FAS 157”), “Fair Value Measurements.” FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements.

The various inputs that may be used to determine the value of the fund’s investments are summarized in three broad levels. The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1—Quoted prices in active markets for identical securities.

Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments).

The following table summarizes the fund’s investments as of August 31, 2008, based on the inputs used to value them:

��

	Investments	Futures
	in Securities	Contracts

Report of Independent Registered

Public Accounting Firm

To the Trustees of Vanguard World Funds and the Shareholders of Vanguard U.S. Growth Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard U.S. Growth Fund (the “Fund”) at August 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2008 by correspondence with the custodian and broker and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2008 tax information (unaudited) for Vanguard U.S. Growth Fund

This information for the fiscal year ended August 31, 2008, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $36,217,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 100% of investment income (dividend income plus short-term gains, if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

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

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income, using actual prior-year figures and estimates for 2008. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

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

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

About Your Fund’s Expenses

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

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

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

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

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

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

Six Months Ended August 31, 2008
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
U.S. Growth Fund	2/29/2008	8/31/2008	Period¹
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,026.39	$2.04
Admiral Shares	1,000.00	1,027.25	1.23
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.19	$2.04
Admiral Shares	1,000.00	1,024.00	1.22

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 0.40% for Investor Shares and 0.24% 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.

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.

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. 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.

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.

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.

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.

Our independent board members bring distinguished backgrounds in business, academia, and public service to their task of working with Vanguard officers to establish the policies and oversee the activities of the funds. Among board members’ responsibilities are selecting investment advisors for the funds; monitoring fund operations, performance, and costs; reviewing contracts; nominating and selecting new trustees/directors; and electing Vanguard officers.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table on these two pages shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

President’s Letter

Dear Shareholder,

In a tumultuous year, Investor Shares of Vanguard International Growth Fund returned a disappointing –12.8% (the lower-cost Admiral Shares returned –12.7%). Nevertheless, the fund outperformed both its benchmark index and the average result of peer funds by about 2 percentage points.

Many stock markets around the globe enjoyed a rousing start to the fiscal year, notching record highs. However, resilience soon gave way to weakness, driving many markets into—or near—bear market territory near the end of the period. Your fund benefited from the advisors’ stock selection in virtually all regions, especially Europe and Latin America. The relative weakness of the U.S. dollar compared with the euro and the yen (but not the British pound) also provided some support for dollar-based investors’ returns, as some foreign holdings became worth more when converted into U.S. dollars.

If you invest in the fund through a taxable account, page 30 shows after-tax returns for investors in the highest tax bracket.

Stocks performed poorly as volatility returned

Stocks lost ground as credit-market turmoil spread throughout the global economy. Over the full 12 months, the broad U.S. stock market lost about 10% of its value. International markets followed a similar path, returning –12.2% for the year.

The descent was bumpy. After years of relative calm, global stock markets routinely rose or fell by more than a percentage point in a day’s trading. The volatility reflected a seemingly endless series of unnerving developments: higher energy prices, further deterioration in the U.S. housing market, several bank failures, and deceleration in the globe’s major economic engines.

Risk-aversion increased, and Treasuries outperformed

As risk-aversion increased, the difference between the yields of Treasury bonds and those of all other securities increased, depressing the price of corporate debt. (Yield and price move in opposite directions.) Even as corporate bonds grew cheaper, the prices of most goods and services rose quickly, powered by escalating energy prices.

dramatic easing of monetary policy through interest rate cuts, even as it recognized that the result might be higher inflation. Over the full 12 months, the Fed reduced its target for the federal funds rate from 5.25% to 2.00%.

As developed markets stumbled, emerging markets cushioned the fall

At the start of the fiscal year, it appeared that fallout from the subprime-mortgage debacle would largely be contained in the United States. In short order, however, the global extent of the credit problems became apparent as foreign banks disclosed significant holdings of U.S. mortgage-related securities. Slower growth coupled with rising inflation crossed the Atlantic from the United States to markets in Europe and beyond, creating stiff headwinds.

Companies based in Europe’s developed countries anchored International Growth’s portfolio. They accounted for about 60% of both the fund’s average value and total return for the period. Even though the fund’s exposure to financial stocks was less than that of its benchmark, the asset write-downs by many overseas banks weighed on the fund’s performance. Among the leading detractors were Anglo Irish Bank, UniCredit (a top-ten holding and one of Europe’s largest banks), UBS, Barclays, and Royal Bank of Scotland.

Consumer discretionary companies in Europe, including automakers BMW and Rolls-Royce Group, also struggled as soaring oil prices and slower growth made customers more budget-conscious. In consumer staples, British retailing giant Tesco, a top-ten holding, also slipped.

Outside of Europe, the fund’s largest position was in Japan, where the long-awaited economic rebound stalled. In midsummer, Japan’s exports fell for the first time in almost five years, depriving many multinational companies and the Japanese economy of an important growth engine. In this environment, the fund benefited from its below-benchmark investment in the country. Among the detractors were Sony, Sumitomo Heavy Industries, and Toray Industries (a chemicals and textile maker).

The fund’s long-standing commitment to emerging markets continued to prove rewarding. All regions except Asia posted gains, led by Latin America (up 17% for the year). In 2007, top-ten holding Petróleo Brasileiro (Petrobras) announced the discovery of an oil field off the coast of Brazil that is potentially one of the world’s largest finds in recent years. Brazilian mining giant Companhia Vale do Rio Doce was boosted by soaring prices for iron ore and other commodities. In Asia, reversing course from last year, many electronics and industrial giants (especially in South Korea) lost ground amid slower demand.

For more about the advisors’ strategies and the fund’s positioning during the year, see the Advisors’ Report—including our first report from M&G Investment Management Limited—which begins on page 7. As discussed in the fund’s semiannual report, M&G (based in London, England) joined the fund’s management team in late February.

The fund’s long-term record remains impressive

For the ten years ended August 31—a period that included intermittent gains and setbacks for international markets—the International Growth Fund bested its comparative standards. This is a tribute to the experience, discipline, and skill of its advisors, who scour the globe—including developing countries—to identify companies with seemingly attractive long-term growth prospects. In addition, the fund’s low expenses help investors keep more of the fund’s return, an advantage that compounds over time.

Diversification is key to long-term success

Not long ago, it appeared that international markets might be moving toward “decoupling,” or becoming more insulated from economic developments in the United States. This view has not been borne out over the last 12 months. But even though foreign markets may experience some of the same ups and downs as those in the United States, they don’t march in lockstep—not with

each other and not with their U.S. counterparts. This divergent performance underscores the potentially significant diversification benefits of investing abroad.

The past year has also provided a valuable reminder of how quickly market trends can reverse. Oil prices are a case in point: After what seemed like an inexorable climb, they abruptly reversed course. Prices of many other commodities followed a similar path. Investors who make frequent portfolio shifts to try to benefit from such trends often end up frustrated, and they can incur additional costs.

Instead, we encourage you to take the long view—to establish a balanced and diversified mix of stocks, bonds, and money market funds that is consistent with your goals, time horizon, and risk tolerance. Then try to stick with your asset allocation plan. As part of your equity portfolio, Vanguard International Growth Fund can help you to capture opportunities that may not be available within U.S. borders.

Thank you for your entrusting your assets

to Vanguard.

Sincerely,

F. William McNabb III

President and Chief Executive Officer

Advisors’ Report

For the fiscal year ended August 31, 2008, Vanguard International Growth Fund’s Investor Shares returned –12.8% (Admiral Shares returned –12.7%). This performance reflects the combined efforts of your fund’s three independent advisors. The use of more than one advisor provides exposure to distinct, yet complementary, investment approaches, enhancing the fund’s diversification.

The advisors, the percentage and amount 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 year and of how their portfolio positioning reflects this assessment. These comments were prepared on September 11, 2008.

For the past 12 months, international markets (represented by the MSCI EAFE Index) returned –14.4% in U.S. dollars. We witnessed a global economic slowdown and the deleveraging of the global banking system. In this context, financial and consumer discretionary stocks performed the worst, while utilities, energy, and consumer staples did best. Currencies showed strong volatility, with the U.S. dollar rebounding sharply toward the end of the fiscal year after prolonged weakness.

The year was punctuated by several shifts in investors’ main concerns. After initially focusing on the immediate fallout from the U.S. subprime-mortgage crisis, investors began to fear the onset of “stagflation.” Expectations of a sharp economic slowdown were combined with worries about increased inflation, driven by steep increases in oil and commodity prices that reflected strength in emerging-market economies. Most recently, inflationary pressures have receded, as we expected, with the deceleration in global growth; this has led to weaker commodities prices, while wage pressures have been mild.

The framework in which businesses operate globally has been marked by pockets of difficulty during the fiscal year, especially for companies that rely on external financing, as most banks have found it difficult to keep up with their past lending activities. In Europe, the interbank market is still tight, and the European Central Bank recently restrained its emergency-lending procedures.

While the markets in peripheral Europe have been weak for a while, those in core Europe decelerated notably during the summer, after being relatively resilient. In the United Kingdom in particular, consumer confidence came under severe pressure as property prices adjusted sharply lower. European banks have been raising capital as deleveraging and asset destruction have intensified. In Switzerland, regulators stepped in to tighten the operating framework, and we expect similar trends throughout Europe in the coming year.

The pace of growth in emerging-market economies also slowed in the fiscal period, but was still healthy compared with the rest of the world. Trading within the region became increasingly important, offsetting the impact of weaker demand for exports (especially to the United States and Europe). Consumers and companies within developing countries also faced increased inflation. While emerging-market equities had been fairly resilient, they have sharply corrected in 2008 as the impact of the global slowdown has intensified. We continue to believe that growth in emerging markets is on a strong secular trend, although there are clear signs of a cyclical slowdown. We believe that this will provide attractive opportunities to further raise our emerging-markets position.

During the period, some of the strongest contributors in our portion of the portfolio included Rio Tinto (a mining company headquartered in the United Kingdom), Syngenta (a Swiss agribusiness firm specializing in crop protection), Unibanco-União de Bancos Brasileiros (Brazilian bank), ArcelorMittal (one of the world’s largest steelmakers, headquartered in Luxembourg), and Honda Motor (Japanese auto company). For the most part, these companies have benefited from strong structural growth linked to climate change, demographics, and emerging-market demand. Although holdings such as Daewoo Shipbuilding & Marine Engineering, a South Korean company, have disappointed, we believe market sentiment has been overly pessimistic, and we expect demand for energy-related shipping vessels to remain buoyant. The market has also

been concerned about companies in Asia, such as hotel group Shangri-La Asia, which was affected by the Sichuan earthquake, and Singapore property company Keppel Land.

Although economic adjustments by consumers and financial deleveraging will continue over the next 12 months, it is important to point out that some countries are now, or soon will be, operating in a negative real interest rate environment, which historically has been beneficial to equities. In addition, valuations are becoming increasingly attractive. In this environment, we continue to strive to identify quality growth companies trading at a reasonable price with sustainable earnings growth.

Head of Global Equities

The fiscal year ended August 31 has been a painful one for equity investors. Media watchers will have amassed ample reasons for gloom, if not despair. The best antidote is to listen to the companies in the portfolio. Some of them are telling us that their short-term outlook has deteriorated. Universally, however, the companies in our portfolio are robustly optimistic about their long-term prospects.

Several firms have reminded us that some parts of the world, China in particular, are still growing strongly. Perhaps even the United States is more resilient than many suppose.

In our view, we are already partway through what might be called “The Big Adjustment.” The largest of the world’s imbalances, the U.S. current account deficit, is shrinking rapidly as currency markets begin to impose a more sustainable pattern on world trade. And the debt-inflated housing markets on both sides of the Atlantic are subsiding to more sensible levels as consumers relearn the attractions of saving. The corporate sector has made good progress in reorienting its sales effort toward the developing world, and banks have begun the painful process of deleveraging, though not all can be expected to survive.

Looking forward, we expect that growth will be slower than before and that credit will be tight. This will create a big problem for the weaker “also ran” companies, especially in the financial sector, so we are starting to look for banks that will benefit from their competitors’ difficulties. The developing world is still the site of most of the economic growth, so we are keeping our big exposure to the emerging markets. Their weak share prices have made us more enthusiastic. We have always liked traditional growth stocks too, and many are now trading at low valuations.

High finance has crash-landed, but the real economy is not in such bad shape. We think our companies can battle through the current crisis and will still be standing when it is over.

Since our appointment as an advisor to the International Growth Fund in late February, our strategy has been directed by our firm belief that a long-term investment horizon supported by bottom-up analysis of company fundamentals is the most effective way to achieve superior returns for investors. Our analysis seeks to identify businesses that have a number of scarce assets that are hard for competitors to replicate, enabling those businesses to achieve high and sustainable returns on capital and to reinvest profitably—thereby increasing the firms’ value and share prices over time.

The ability of these companies to generate sustainable returns also makes them attractive to investors in uncertain times. As such, we believe our portion of the portfolio is well-positioned to deal with the current difficult market environment and, more important, the future.

Our holdings are well-diversified: About 60% of the portfolio is invested in Europe, about 25% is in Asia, and the remainder in Canada, Central and South America, and South Africa. While this geographical positioning is a product of bottom-up company analysis rather than any top-down views on individual countries, it is worth mentioning that we invest directly in some of the world’s developing markets, where we can find quality companies supported by higher-than-average levels of economic growth. From a sector perspective, the portfolio’s main relative exposures have been an overweighting to health care and an underweighting to financials—again, positions that result from the merits of the underlying companies, rather than a view on the sectors as a whole.

Our overweighted position in health care proved beneficial amid strong performances by large, defensive pharmaceutical businesses such as Switzerland’s Novartis and the United Kingdom’s GlaxoSmithKline, following an extended period of underperformance. During a volatile period for financials, our stock selection in this area was a positive. Solid contributions to performance came from U.K.-listed HSBC Holdings, the high-quality global bank with emerging-market exposure, and Dutch financials giant ING Groep, whose product and geographical diversification should help it to sustain superior returns.

In contrast, the main detractors in our portfolio included Canadian nickel and coal producer Sherritt International, which was hurt by declines in commodities prices; Swiss cement business Holcim, which faced fears over challenging end markets; and Austrian building-products maker Wienerberger, which suffered from negative sentiment toward the construction industry.

We will continue to focus on a broad range of differentiated businesses whose scarce assets should enable them to generate high returns and to grow over the long term. We believe this approach will enable the fund to ride out periods of volatility, such as those currently affecting financial markets, and will thereby provide superior returns for investors in the long run.

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 United States 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 values 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 European and Pacific stock markets 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 the contracts.

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 on federal income tax returns for all open tax years (tax years ended August 31, 2005–2008), 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.

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. In accordance with the advisory contract entered into with M&G Investment Management Ltd. in February 2008, beginning December 1, 2008, the investment advisory fee will be subject to quarterly adjustments based on performance since February 29, 2008, relative to the MSCI All Country World Index excluding USA.

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

For the year ended August 31, 2008, the aggregate investment advisory fee represented an effective annual basic rate of 0.12% of the fund’s average net assets before an increase of $3,220,000 (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 August 31, 2008, the fund had contributed capital of $1,515,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.51% 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. The fund’s custodian bank has also agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the year ended August 31, 2008, these arrangements reduced the fund’s management and administrative expenses by $270,000 and custodian fees by $19,000. The total expense reduction represented an effective annual rate of 0.00% of average net assets.

During the year ended August 31, 2008, the fund realized net foreign currency gains of $6,477,000, which increased distributable net income for tax purposes; accordingly, such gains have been reclassified from accumulated net realized gains to undistributed net investment income. The fund used a tax accounting practice to treat a portion of the price of capital shares redeemed during the year as distributions from net investment income and realized capital gains. Accordingly, the fund has reclassified $28,978,000 from undistributed net investment income, and $79,910,000 from accumulated net realized gains, to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $324,563,000 of ordinary income and $725,620,000 of long-term capital gains available for distribution.

At August 31, 2008, the cost of investment securities for tax purposes was $16,804,351,000. Net unrealized appreciation of investment securities for tax purposes was $160,984,000, consisting of unrealized gains of $2,124,090,000 on securities that had risen in value since their purchase and $1,963,106,000 in unrealized losses on securities that had fallen in value since their purchase.

At August 31, 2008, the aggregate settlement value of open futures contracts expiring in September 2008 and the related unrealized appreciation (depreciation) were:

			($000)
	Number of	Aggregate	Unrealized

The fund had net unrealized foreign currency losses of $1,070,000 resulting from the translation of other assets and liabilities at August 31, 2008.

F. During the year ended August 31, 2008, the fund purchased $11,009,060,000 of investment securities and sold $9,837,589,000 of investment securities other than temporary cash investments.

Report of Independent Registered

Public Accounting Firm

To the Trustees of Vanguard World Funds and the Shareholders of Vanguard International Growth Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard International Growth Fund (the “Fund”) at August 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2008 by correspondence with the custodian and brokers and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Your Fund’s After-Tax Returns

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

Average Annual Total Returns: International Growth Fund Investor Shares¹
Periods Ended August 31, 2008
	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	–12.83%	13.93%	7.01%
Returns After Taxes on Distributions	–14.54	12.78	5.95
Returns After Taxes on Distributions and Sale of Fund Shares	–6.48	11.99	5.76

1 Total returns do not reflect the 2% fee assessed on redemptions of shares purchased on or after June 27, 2003, and held for less than two months, nor do they include the account service fee that may be applicable to certain accounts with balances below $10,000.

About Your Fund’s Expenses

The table below 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.

Six Months Ended August 31, 2008
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
International Growth Fund	2/29/2008	8/31/2008	Period¹
Based on Actual Fund Return
Investor Shares	$1,000.00	$896.45	$2.10
Admiral Shares	1,000.00	897.30	1.24
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.99	$2.24
Admiral Shares	1,000.00	1,023.89	1.33

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 0.44% for Investor Shares and 0.26% 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.

Note that the expenses shown in the table on the previous page 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 that applies to shares purchased on or after June 27, 2003, and 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.”

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.

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.

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

President’s Letter

Dear Shareholder,

Over the 12 months ended August 31, Vanguard FTSE Social Index Fund’s performance reflected the troubles plaguing the U.S. stock market. The fund’s Investor Shares returned –15.3% for the 2008 fiscal year and its Institutional Shares –15.2%. The fund achieved its primary goal of closely tracking its target, the FTSE4Good US Select Index, which closed the period with a return of –15.1%.

The persistent upheaval in the financial industry didn’t bode well for the index, given its heavy weighting in the sector. At the other end of the spectrum, the index’s top performers were energy and materials stocks.

If you hold shares of the fund in a taxable account, you may wish to review our report on after-tax returns on page 23.

As market volatility intensified, stocks declined worldwide

unnerving developments: the persistent rise in energy prices, further deterioration in the housing market, several bank failures, and the broad economy’s deceleration.

Risk-aversion increased, and Treasuries outperformed

The combination of higher inflation, financial market volatility, and economic weakness put the U.S. Federal Reserve Board in an uncomfortable position. The Fed decided that it was imperative to respond to the financial crisis with a dramatic easing of monetary policy through interest rate cuts, even as it recognized that the result might be higher inflation. Over the full 12 months, the Fed reduced its target for the federal funds rate from 5.25% to 2.00%.

Holdings in financials proved burdensome

Over the fiscal year ended August 31, the performance of Vanguard FTSE Social Index Fund closely tracked that of the FTSE4Good US Select Index, the fund’s target benchmark. The index’s socially conscious mandate—which favors companies that work to protect the environment, maintain fair hiring and promotion practices for women and minorities, and institute safe and healthy workplace habits—sets it apart from the average large-cap growth fund.

The index provider’s screening criteria generally lead to a portfolio heavily weighted in the financial, consumer discretionary, and health care sectors. The index typically has limited exposure to stocks in the energy, materials, and utilities groups. This stock mix can work well in some market environments, but not so well in others. The past 12 months provided an example of the latter: The energy and materials sectors were among the top contributors in the broad market, while financial stocks were among the worst performers.

The index’s large allocation to the financial sector, which fell more than 30% for the period, was a major factor in its disappointing performance. As the credit crisis intensified, banks, brokerages, insurers, and other financial-service providers booked substantial credit-related losses.

Information technology companies were also big detractors. Internet companies such as Google and Yahoo! saw their

1 Fund expense ratios shown are from the prospectus dated December 10, 2007. The expense ratios for the fiscal year ended August 31, 2008, were 0.24% for Investor Shares and 0.11% for Institutional Shares.

stocks decline as online advertising sales hit a rough patch. Semiconductor companies were hurt by slower growth in demand for computer chips. Consumer discretionary stocks felt the effects of the broad economic slowdown as Americans had less money to spend on shopping and eating out.

Throughout the 12-month period, energy stocks were the shining stars of the index. As oil prices rose, coal and exploration companies turned in exceptional performances. Continued economic expansion in emerging markets heightened the demand for commodities, giving materials stocks a boost.

The fund’s long-term results are on track with its benchmark

Since the FTSE Social Index Fund’s inception in May 2000, two significant stock market downturns (2000–2002 and the current one) have hurt the fund’s long-term performance, resulting in an average annual return of –2.0%. Although negative, the fund’s average return is higher than that of the average large-cap growth fund and is closely aligned with that of its benchmark index.

For the five-year period ended August 31, 2008, the fund’s Investor Shares returned an average of 3.8% a year, again closely tracking the benchmark’s average annual return of 4.0% for the same period.

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

3 Derived from data provided by Lipper Inc.

As this record shows, the fund’s advisor, Vanguard Quantitative Equity Group, has done an exceptional job of tracking the fund's target index. The advisor’s accuracy is supported by the fund’s expense ratio, which is much lower than the average cost of peer funds.

A long-term perspective is key during turbulent times

As trouble continued in the U.S. economy, the markets have seen sometimes startling volatility. Over the past 12 months, Vanguard FTSE Social Index Fund experienced its share of the ups and downs. Such volatility is a good reminder of why we urge shareholders to avoid reacting to short-term market “noise.” Instead, Vanguard suggests that you maintain both a well-balanced portfolio and a long-term perspective.

A well-balanced portfolio includes stock funds, bond funds, and short-term reserves in proportions that fit your goals and risk tolerance. Such a carefully planned investment program can help to cushion the stock market’s occasionally sharp declines while allowing you to participate in its long-term potential for growth.

For socially conscious investors, Vanguard FTSE Social Index Fund offers a low-cost option that can play an important role in this kind of long-term investment plan.

Thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

President and Chief Executive Officer

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 of $5 million.

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 on federal income tax returns for all open tax years (tax years ended August 31, 2005–2008), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

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 August 31, 2008, the fund had contributed capital of $45,000 to Vanguard (included in Other Assets), representing 0.01% 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. 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.

For tax purposes, at August 31, 2008, the fund had $5,302,000 of ordinary income available for distribution. The fund had available realized losses of $4,064,000 to offset future net capital gains of $79,000 through August 31, 2012, $985,000 through August 31, 2013, $367,000 through August 31, 2014, $2,136,000 through August 31, 2016, and $497,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $560,321,000. Net unrealized depreciation of investment securities for tax purposes was $25,289,000, consisting of unrealized gains of $68,988,000 on securities that had risen in value since their purchase and $94,277,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $240,752,000 of investment securities and sold $251,503,000 of investment securities other than temporary cash investments.

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

Net Increase (Decrease)—Institutional Shares	51,023	5,980		16,384	1,784

F. In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 157 (“FAS 157”), “Fair Value Measurements.” FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements.

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 August 31, 2008, 100% of the fund’s investments were valued based on Level 1 inputs.

Report of Independent Registered

Public Accounting Firm

To the Trustees of Vanguard World Funds and the Shareholders of Vanguard FTSE Social Index Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard FTSE Social Index Fund (the “Fund”) at August 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2008 by correspondence with the custodian and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2008 tax information (unaudited) for Vanguard FTSE Social Index Fund

This information for the fiscal year ended August 31, 2008, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $9,873,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 100% of investment income (dividend income plus short-term gains, if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

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

Average Annual Total Returns: FTSE Social Index Fund Investor Shares¹
Periods Ended August 31, 2008

	Year	Years	Inception²
Returns Before Taxes	–15.26%	3.80%	–2.05%

About Your Fund’s Expenses

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

Six Months Ended August 31, 2008
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
FTSE Social Index Fund	2/29/2008	8/31/2008	Period¹
Based on Actual Fund Return
Investor Shares	$1,000.00	$978.56	$1.15
Institutional Shares	1,000.00	978.59	0.50
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,024.05	$1.17
Institutional Shares	1,000.00	1,024.70	0.51

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 0.23% for Investor Shares and 0.10% 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.

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard FTSE Social Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group (QEG)—serves as the investment advisor for the fund. The board determined that continuing the fund’s internalized management structure was in the best interests of the fund and its shareholders.

The board based its decision upon an evaluation of the 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 arrangement. 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 the advisor. The board noted that Vanguard has been managing investments for more than 25 years. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985. Mr. Sauter has led QEG since 1987. QEG adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

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

Investment performance

The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of its target benchmark and peer group. The board concluded that the fund has performed in line with expectations and that its results have been consistent with its investment strategy. 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 far below the average expense ratio charged by funds in its peer group. The board noted that the fund’s advisory expense ratio 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.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

The benefit of economies of scale

The board concluded that the fund’s low-cost arrangement with Vanguard ensures that the fund will realize economies of scale as it grows, with the cost to shareholders declining as the fund’s assets increase.

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

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.

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.

President’s Letter

Dear Shareholder,

The Vanguard U.S. Sector Index Funds faced stiff headwinds during the latest fiscal year. The overall stock market declined, the economy slowed as energy-led inflation rose, and concern about the impact of the subprime-mortgage crisis continued to swell.

As you would expect, the continuing credit-market distress stemming from widespread mortgage defaults undercut financial sector stocks, which posted the worst returns of all the sectors. At the other extreme, energy sector stocks (with exceptions) were bolstered by rising oil prices and turned in the best performance as a group.

Seven of the sector funds outpaced the –9.9% return of the broad stock market for the year, but only the Energy, Materials, and Consumer Staples Index Funds had positive returns. The Financials, Telecommunication Services, and Consumer Discretionary Index Funds underperformed the market, posting double-digit declines.

As market volatility intensified, stocks sagged worldwide

Stocks in many markets lost ground as credit-market turmoil spread throughout the global economy. Over the full 12 months, the broad U.S. stock market lost about –10% of its value. International markets followed a similar path, returning –12.2% for the year.

The descent was bumpy. After years of relative calm, the U.S. market routinely rose or fell by more than a percentage point in a day’s trading. The volatility reflected a seemingly endless series of unnerving developments: the persistent rise in energy prices, further deterioration in the housing market, a string of bank failures, and the broad economy’s deceleration.

Risk-aversion increased, and Treasuries outperformed

The combination of higher inflation, financial market volatility, and economic weakness put the U.S. Federal Reserve Board in an uncomfortable position. The Fed decided that it was imperative to respond to the financial crisis with a dramatic easing of monetary policy through interest rate cuts, even as it recognized that the result might be higher inflation. Over the full 12 months, the Fed reduced its target for the federal funds rate from 5.25% to 2.00%.

Energy and financial sectors traveled very separate paths

Even as the U.S. economy was decelerating, worldwide demand for commodities such as oil and grains remained strong for much of the year. The share prices of exploration and production companies and coal companies climbed strongly in this climate of high and rising energy prices, although the impact on giant integrated oil companies was mixed. The net result was a 9.4% gain for the Energy Index Fund, the top-performing sector fund.

In the materials sector, agricultural chemical companies Monsanto and Mosaic benefited from strong worldwide demand for products to improve crop yields. These two companies were the primary drivers behind the Materials Index Fund’s 4.1% return.

As is typical during economic slowdowns, consumers continued to spend on basic products and services. Reflecting this, the Consumer Staples Index Fund returned 4.1% for the year. In sharp contrast, the Consumer Discretionary Index Fund returned –18.7% as Americans cut back on postponable spending, another true-to-form characteristic of the economic cycle. Especially hard hit were the stocks of movie, publishing, broadcasting, and cable television businesses; leisure-activity companies; and retailers (although the giant retailer Wal-Mart Stores—a consumer staples company—was a strong exception to this trend).

The Utilities Index Fund had a nearly flat return (–0.7%). The Health Care Index Fund returned –2.6%, pulled down by its holdings in managed health care companies and a number of pharmaceutical firms.

The Industrials and Information Technology Index Funds produced identical returns of –8.7%. Tech stocks suffered as both consumers and businesses—which count the ailing financial sector as a major customer—slowed spending on technology. Leading the decline in industrials was General Electric.

The Telecommunication Services Index Fund, which includes companies such as AT&T, Sprint Nextel, and Verizon that compete fiercely for market share, returned –21.0%. The Financials Index Fund was the worst performer for the year, returning –30.4% as investors increasingly lost confidence in the balance sheets of many financial firms.

The funds’ advisor, Vanguard Quantitative Equity Group, generally succeeded in capturing the returns of the target indexes. The exceptions to this pattern were the Energy Index, Consumer Staples Index, and Telecommunication Services Index Funds. Regulatory limits on holdings of individual securities precluded these funds from completely replicating the characteristics of their respective indexes.

Diversification and low cost were never more important

The varied performances of the Vanguard Sector Index Funds during the past fiscal year underscore a fundamental principle of sound investing: the need for diversification. The value of this principle has become especially clear during the past few months, as the crisis that started with subprime mortgages rippled through the financial markets.

No one knows for sure what will happen in the markets from day to day or year to year. A diversified portfolio can do much to help dampen the risk that comes with both normal and heightened degrees of investing uncertainty.

The Vanguard U.S. Sector Index Funds are an efficient way to round out your portfolio. Even better, they’re a low-cost alternative to competing funds. This is important because low costs allow you to keep more of what you earn—yet another foundational principle of smart investing. (Please note that the expense ratios shown in the following Profile pages are those of the 2007 annual report. For the funds’ expense ratios in the most recent reporting period, please see the Financial Highlights tables.)

Thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

President and Chief Executive Officer

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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $19,000 to Vanguard (included in Other Assets), representing 0.01% 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.

future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

Consumer Discretionary Index Fund

During the year ended August 31, 2008, the fund realized $7,765,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $1,380,000 of ordinary income available for distribution. The fund had available realized losses of $6,213,000 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, $1,527,000 through August 31, 2016, and $4,386,000 through August 31, 2017.

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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $39,000 to Vanguard (included in Other Assets), representing 0.01% 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.

Consumer Staples Index Fund

During the year ended August 31, 2008, the fund realized $24,902,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $6,116,000 of ordinary income available for distribution. The fund had available realized losses of $6,539,000 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 $3,229,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $525,825,000. Net unrealized appreciation of investment securities for tax purposes was $10,974,000, consisting of unrealized gains of $28,728,000 on securities that had risen in value since their purchase and $17,754,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $392,283,000 of investment securities and sold $177,090,000 of investment securities, other than temporary cash investments.

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

ETF Shares were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $82,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.08% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

During the year ended August 31, 2008, the fund realized $62,294,000 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.

Energy Index Fund

For tax purposes, at August 31, 2008, the fund had $7,538,000 of ordinary income available for distribution. The fund had available realized losses of $12,978,000 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 $10,029,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $805,589,000. Net unrealized appreciation of investment securities for tax purposes was $180,176,000, consisting of unrealized gains of $189,507,000 on securities that had risen in value since their purchase and $9,331,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $381,785,000 of investment securities and sold $230,272,000 of investment securities, other than temporary cash investments.

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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $59,000 to Vanguard (included in Other Assets), representing 0.01% 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.

Financials Index Fund

During the year ended August 31, 2008, the fund realized $7,014,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $4,144,000 of ordinary income available for distribution. The fund had available realized losses of $9,066,000 to offset future net capital gains of $85,000 through August 31, 2014, $11,000 through August 31, 2015, $1,312,000 through August 31, 2016, and $7,658,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $935,413,000. Net unrealized depreciation of investment securities for tax purposes was $199,972,000, consisting of unrealized gains of $9,827,000 on securities that had risen in value since their purchase and $209,799,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $724,470,000 of investment securities and sold $104,319,000 of investment securities, other than temporary cash investments.

E. 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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $56,000 to Vanguard (included in Other Assets), representing 0.01% 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 year ended August 31, 2008, the fund realized $9,780,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $7,011,000 of ordinary income available for distribution. The fund had available realized losses of $10,277,000 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 $6,601,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $768,452,000. Net unrealized depreciation of investment securities for tax purposes was $19,119,000, consisting of unrealized gains of $59,099,000 on securities that had risen in value since their purchase and $78,218,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $282,902,000 of investment securities and sold $109,465,000 of investment securities, other than temporary cash investments.

E. 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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $25,000 to Vanguard (included in Other Assets), representing 0.01% 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.

During the year ended August 31, 2008, the fund realized $21,887,000 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.

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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $42,000 to Vanguard (included in Other Assets), representing 0.01% 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.

Information Technology Index Fund

During the year ended August 31, 2008, the fund realized $41,247,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $2,217,000 of ordinary income available for distribution. The fund had available realized losses of $9,645,000 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 $8,564,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $574,512,000. Net unrealized depreciation of investment securities for tax purposes was $51,432,000, consisting of unrealized gains of $17,173,000 on securities that had risen in value since their purchase and $68,605,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $420,580,000 of investment securities and sold $282,704,000 of investment securities, other than temporary cash investments.

E. 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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $44,000 to Vanguard (included in Other Assets), representing 0.01% 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.

During the year ended August 31, 2008, the fund realized $40,528,000 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.

Materials Index Fund

For tax purposes, at August 31, 2008, the fund had $5,003,000 of ordinary income available for distribution. The fund had available realized losses of $7,506,000 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 $5,344,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $487,834,000. Net unrealized depreciation of investment securities for tax purposes was $11,777,000, consisting of unrealized gains of $36,802,000 on securities that had risen in value since their purchase and $48,579,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $292,915,000 of investment securities and sold $188,871,000 of investment securities, other than temporary cash investments.

E. 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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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 Admiral Shares are credited to paid-in capital.

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 August 31, 2008, the fund had contributed capital of $14,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. 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 year ended August 31, 2008, custodian fee offset arrangements reduced the fund’s expenses by $4,000 (an annual rate of 0.00% of average net assets).

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

During the year ended August 31, 2008, the fund realized $10,786,000 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.

Telecommunication Services Index Fund

For tax purposes, at August 31, 2008, the fund had $3,351,000 of ordinary income available for distribution. The fund had available realized losses of $23,011,000 to offset future net capital gains of $29,000 through August 31, 2014, $819,000 through August 31, 2015, $4,154,000 through August 31, 2016, and $18,009,000 through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $204,119,000. Net unrealized depreciation of investment securities for tax purposes was $41,457,000, consisting of unrealized gains of $1,155,000 on securities that had risen in value since their purchase and $42,612,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2008, the fund purchased $156,069,000 of investment securities and sold $250,490,000 of investment securities, other than temporary cash investments.

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

G. In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 157 (“FAS 157”), “Fair Value Measurements.” FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements.

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 August 31, 2008, 100% of the fund’s investments were valued based on Level 1 inputs.

1 Net of redemption fees of $220,000 and $110,000 (fund totals).

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 were listed for trading on the American Stock Exchange through September 18, 2008, and on the NYSE Arca, Inc., thereafter; they can be purchased and sold through a broker.

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

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $41,000 to Vanguard (included in Other Assets), representing 0.01% 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.

During the year ended August 31, 2008, the fund realized $5,120,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $3,018,000 of ordinary income available for distribution. The fund had available realized losses of $2,410,000 to offset future net capital gains of $515,000 through August 31, 2015, and $1,895,000 through August 31, 2017.

Utilities Index Fund

At August 31, 2008, the cost of investment securities for tax purposes was $503,703,000. Net unrealized depreciation of investment securities for tax purposes was $24,302,000, consisting of unrealized gains of $9,748,000 on securities that had risen in value since their purchase and $34,050,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2008, the fund purchased $216,561,000 of investment securities and sold $106,108,000 of investment securities, other than temporary cash investments.

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

We believe that our audits, which included confirmation of securities at August 31, 2008 by correspondence with the custodian and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

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:

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 one year. If this fee were applied to your account, your costs would be higher. Your fund does not carry a “sales load.”

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 0.25% for the Consumer Discretionary Index Fund Admiral Shares and 0.19% for the ETF Shares; 0.24% for the Consumer Staples Index Fund Admiral Shares and 0.19% for the ETF Shares; 0.25% for the Energy Index Fund Admiral Shares and 0.20% for the ETF Shares; 0.24% for the Financials Index Fund Admiral Shares and 0.19% for the ETF Shares; 0.24% for the Health Care Index Fund Admiral Shares and 0.19% for the ETF Shares; 0.24% for the Industrials Index Fund Admiral Shares and 0.19% for the ETF Shares; 0.24% for the Information Technology Index Fund Admiral Shares and 0.19% for the ETF Shares; 0.24% for the Materials Index Fund Admiral Shares and 0.19% for the ETF Shares; 0.25% for the Telecommunication Services Index Fund Admiral Shares and 0.20% for the ETF Shares; 0.25% for the Utilities Index Fund Admiral Shares and 0.19% 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, then divided by the number of days in the most recent 12-month period.

Trustees Approve Advisory Arrangement

The board of trustees of the Vanguard U.S. Sector Index Funds has renewed the funds’ investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group (QEG)—serves as the investment advisor for the funds. The board determined that continuing the funds’ internalized management structure was in the best interests of the funds and their shareholders.

Nature, extent, and quality of services

The board considered the quality of the funds’ investment management over both the short and long term, and took into account the organizational depth and stability of the advisor. The board noted that Vanguard has been managing investments for more than 25 years. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985 and has led QEG since 1987. QEG adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

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

Investment performance

The board considered the short- and long-term performance of the funds, including any periods of outperformance or underperformance of their target benchmarks and peer groups. The board noted that the funds have performed in line with expectations, and that their results have been consistent with their investment strategies. Information about the funds’ most recent performance can be found in the Performance Summary sections of this report.

Cost

The board concluded that the funds’ expense ratios were far below the average expense ratios charged by funds in their respective peer groups. The board noted that the funds’ advisory expense ratios were also well below their peer-group averages. Information about the funds’ expense ratios appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements sections.

The benefit of economies of scale

The board concluded that the funds’ low-cost arrangement with Vanguard ensures that each fund will realize economies of scale as it grows, with the cost to shareholders declining as fund assets increase.

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

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 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.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table below shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

President’s Letter

Dear Shareholder,

I am pleased to present the first “annual report” for Vanguard Extended Duration Treasury Index Fund. This bond fund, which was launched November 28, 2007, is designed especially for institutional investors, including pension funds and endowments, that manage portfolios with very long time horizons.

For the fiscal period ended August 31, 2008, the fund’s Institutional Shares returned 0.4%, slightly short of the return of the fund’s target index, the Lehman U.S. Treasury STRIPS 20–30 Year Equal Par Bond Index. The fund’s ETF Shares, which were first offered on December 6, 2007, returned 2.3% based on their net asset value.

Risk-aversion increased, and Treasuries outperformed

During the fiscal period, the collapse in subprime mortgage-backed securities and the aftershocks prompted a “flight to safety” among investors. Short-term U.S. Treasury securities were among the fixed income market’s best performers. Over the 12 months, the broad taxable bond market returned a respectable 5.9%, largely reflecting the Treasury bond rally.

The combination of higher inflation, financial market volatility, and economic weakness put the U.S. Federal Reserve Board in an uncomfortable position. The Fed decided that it was imperative to respond to the financial crisis with a dramatic easing of monetary policy through interest rate cuts, even as it recognized that the result might be higher inflation. Over the full 12 months, the Fed reduced its target for the federal funds rate from 5.25% to 2.00%.

Stocks performed poorly as volatility returned

Stocks lost ground as credit-market turmoil spread throughout the global economy. The broad U.S. stock market lost about 10% of its value. International markets followed a similar path, returning –12.2% for the year.

The descent was bumpy. After years of relative calm, the U.S. market routinely rose or fell by more than a percentage point in a day’s trading. The volatility reflected a seemingly endless series of unnerving developments: the persistent rise in energy prices, further deterioration in the housing market, a string of bank failures, and the broad economy’s deceleration.

Your extended bond fund held steady despite Treasury yield fluctuations

The Extended Duration Treasury Index Fund invests in zero-coupon Treasury securities with maturities ranging from 20 to 30 years. The fund’s manager, Vanguard Fixed Income Group, aims to provide institutional and other investors with a tool to moderate changes in the ratio of their long-term assets and obligations.

MSCI All Country World Index ex USA (International)	–12.2	10.7	16.1


CPI
Consumer Price Index	5.4%	3.7%	3.5%

The fund’s usefulness in managing this longer-term risk comes, paradoxically, with the potential for high levels of short-term volatility in total return. The Extended Duration Treasury Index Fund consists almost entirely of long-term bonds, making its short-term returns highly sensitive to changes in interest rates.

During the fund’s fiscal period, U.S. Treasury yields fluctuated, moving higher across the board toward the end of the period. The impact on the fund was nevertheless limited, as much of the interest-rate volatility took place among short-term and intermediate-term securities.

The long-term bonds held by the Extended Duration Treasury Index Fund experienced only slight increases in yields and consequent declines in prices. The fund’s total return of 0.4% reflected approximately 2.0% in income return and a capital change of –1.6%. These returns were slightly less than those of the fund’s target benchmark index, which incurs no operating expenses.

For a young fund, an experienced advisor

While it is too early to discuss the long-term performance of the Extended Duration Treasury Index Fund, investors can be confident that Vanguard Fixed Income Group has years of experience in managing index funds.

The Fixed Income Group uses sophisticated trading strategies and sampling techniques to seek to create a portfolio that closely matches its benchmark index.

Expense Ratios¹

	Institutional	ETF
	Shares	Shares
Extended Duration Treasury Index Fund	0.11%	0.14%

1 Fund expense ratios shown are from the prospectus dated September 10, 2007 and were based on estimated expenses. The annualized expense ratios for the fiscal period ended August 31, 2008, were 0.11% for Institutional Shares and 0.14% for ETF Shares.

And Vanguard’s commitment to low costs allows investors to keep a greater portion of their fund’s returns.

The fund offers diversification for long-term institutional portfolios

Heightened volatility in the markets can be worrisome for both novice investors and experienced managers of institutional portfolios.

While periodic market fluctuations are bound to take place, a diversified portfolio focused on the long term can help moderate short-term volatility in total returns. The Extended Duration Treasury Index Fund can also provide special benefits to institutions and other investors with long time horizons and obligations that extend well into the future. Its low-cost exposure to long-term Treasury securities offers both diversification opportunities and the potential to better manage long-term liabilities.

Thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

Notes to Financial Statements

Vanguard Extended Duration Treasury Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers three classes of shares: Institutional Shares, Institutional Plus Shares, and ETF Shares. Institutional Shares were first issued on November 28, 2007, and are designed for investors who meet certain administrative and service criteria and invest a minimum of $5 million. Institutional Plus Shares are available to investors who invest a minimum of $100 million. The fund had not issued any Institutional Plus Shares through August 31, 2008. ETF Shares were first issued on December 6, 2007, and first offered to the public on December 10, 2007. ETF Shares were listed for trading on the American Stock Exchange through September 18, 2008, and on NYSE Arca, Inc. thereafter; they can be purchased and sold through a broker.

1. 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 materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value.

2. Federal Income Taxes: The fund intends to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for the period from inception to August 31, 2008, 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.

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 August 31, 2008, the fund had contributed capital of $17,000 to Vanguard (included in Other Assets), representing 0.01% 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.

During the period ended August 31, 2008, the fund realized $479,000 of net capital losses resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such losses are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $1,865,000 of ordinary income available for distribution. The fund had available realized losses of $435,000 to offset future net capital gains through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $263,028,000. Net unrealized appreciation of investment securities for tax purposes was $211,000, consisting of unrealized gains of $1,191,000 on securities that had risen in value since their purchase and $980,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended August 31, 2008, the fund purchased $315,646,000 of investment securities and sold $56,119,000 of investment securities other than temporary cash investments.

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

To the Trustees of Vanguard World Funds and the Shareholders of Vanguard Extended Duration Treasury Index Fund:

In our opinion, the accompanying statement of net assets, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Extended Duration Treasury Index Fund (the “Fund”) at August 31, 2008, the results of its operations, the changes in its net assets and the financial highlights for the period November 28, 2007 (commencement of operations) through August 31, 2008, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities at August 31, 2008 by correspondence with the custodian and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

About Your Fund’s Expenses

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

Six Months Ended August 31, 2008
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Extended Duration Treasury Index Fund	2/29/2008	8/31/2008	Period¹
Based on Actual Fund Return
Institutional Shares	$1,000.00	$1,032.57	$0.56
ETF Shares	1,000.00	1032.46	0.72
Based on Hypothetical 5% Yearly Return
Institutional Shares	$1,000.00	$1,024.65	$0.56
ETF Shares	1,000.00	1024.50	0.71

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 0.14% 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.

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard Extended Duration Treasury Index Fund has renewed the investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Fixed Income Group (FIG)—serves as the investment advisor for the fund. The board determined that continuing the fund’s internalized management structure 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 services provided by FIG since the fund’s inception in 2007, and took into account the organizational depth and stability of the advisor. The board noted that Vanguard has been managing investments for more than 25 years. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985. Robert F. Auwaerter, head of Fixed Income Portfolio Management and principal of Vanguard, has been in the investment management business since 1978. FIG adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

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

Investment performance

The board considered the fund’s performance since inception, including any periods of outperformance or underperformance of its target benchmark and peer group. The board concluded that the fund has performed in line with expectations, and that the results have been consistent with the fund’s investment strategy. Information about the fund’s performance can be found in the Performance Summary section of this report.

Cost

The benefit of economies of scale

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

President’s Letter

Dear Shareholder,

Vanguard Mega Cap 300 Index Fund, Mega Cap 300 Value Index Fund, and Mega Cap 300 Growth Index Fund—which launched ETF Shares on December 17, 2007—are designed to capture the performance of the largest stocks in the U.S. market. The funds track the MSCI US Large Cap Indexes and allow you to invest in the market segment as a whole or directly in its growth or value components.

The funds were introduced during a turbulent time in the U.S. markets, and have endured difficult times since the very beginning. From inception through August 31, the Mega Cap 300 Growth Index Fund was the top performer of the group, with its ETF Shares returning –5.9% for the period, as determined by the net asset value per share. The Mega Cap 300 Index ETF was next in line, returning –9.6% for the period, while the Mega Cap 300 Value Index ETF returned –13.6%.

Despite the unsettled investment environment, the fund’s advisor, Vanguard Quantitative Equity Group, has managed to closely track the funds’ target indexes. The advisor is helped in this task by the funds’ expense ratios, which are much lower than the average costs of peer funds.

The Mega Cap 300 Index Funds also offer Institutional Shares, which are available for a minimum initial investment of $5,000,000. The table on pages 1 and 2 shows the returns for the funds and their target indexes and the average returns for their peer groups for the period.

As market volatility intensified, stocks declined worldwide

Although the funds began operations after the start of their fiscal year, we provide a review of the investment environment during the full 12 months.

Stocks lost ground as credit-market turmoil spread throughout the global economy. Over the 12 months, the broad U.S. stock market lost about 10% of its value. International markets followed a similar path, returning –12.2% for the year.

The descent was bumpy. After years of relative calm, the U.S. market routinely rose or fell by more than a percentage point in a day’s trading. The volatility reflected a seemingly endless series of unnerving developments: the persistent rise in energy prices, further deterioration in the housing market, a string of bank failures, and the broad economy’s deceleration.

Risk aversion increased, and Treasuries outperformed

As risk aversion increased, the difference between the yields of Treasury bonds and those of all other securities increased, depressing the price of corporate debt. (As you know, yield and price move in opposite directions.) Even as corporate bonds grew cheaper, the prices of most goods and services rose quickly, powered by escalating energy prices.

The combination of higher inflation, financial market volatility, and economic weakness put the U.S. Federal Reserve Board in an uncomfortable position. The Fed decided that it was imperative to respond to the financial crisis with a dramatic easing of monetary policy through interest rate cuts, even as it recognized that the result might be higher inflation. Over the full 12 months, the Fed reduced its target for the federal funds rate from 5.25% to 2.00%.

Trouble in financials hindered index returns

As the turmoil in the U.S. markets continued, all three Mega Cap 300 Index Funds reported negative returns for the period ended August 31, 2008. The persistent upheaval in the financial industry didn’t bode well for the Mega Cap 300 Value Index Fund in particular, given its heavy weighting in the sector. The Mega Cap 300 Growth Index Fund—which significantly outperformed its peers—fared relatively well, mostly because of its more modest allocation to financial stocks and positive results from the consumer staples and materials sectors.

The Mega Cap 300 Value Index’s large allocation to the financial sector was a major factor in its disappointing performance. As the credit crisis endured, mortgage giants Freddie Mac and Fannie Mae were thrown into turmoil. Investment banks and insurers also suffered from credit-related losses.

Information technology companies were the biggest detractors for the Mega Cap 300 Growth Index Fund, as software and hardware makers negotiated a slowdown in key markets. Industrial stocks also performed weakly.

In the health care sector, pharmaceutical and managed health care stocks struggled, hindering the performance of all three indexes. Consumer discretionary stocks felt the effects of the broad economic slowdown as Americans had less money to spend on the nonessentials.

While the value index reported losses in all market sectors for the period, the growth index saw a couple of bright spots. In the consumer staples sector, jumbo retailer Wal-Mart Stores was up 25% for the period. Fertilizer companies and mining companies contributed to the positive performance of the materials sector.

A long-term perspective is key despite market conditions

Amid continued trouble in the U.S. economy, the financial markets have seen sometimes startling volatility. Since their inception in December of 2007, the Vanguard Mega Cap 300 Index Funds have already experienced their fair share of ups and downs. Such volatility is a good reminder of why we urge shareholders to avoid reacting to short-term market “noise.” Instead, Vanguard suggests that you maintain both a well-balanced portfolio and a long-term perspective.

The lineup of Vanguard Mega Cap 300 Index Funds offers shareholders a low-cost way to invest in the large-cap area of the market as a whole, or solely in the growth or value segments. Whatever your preference, these funds can play an important role in your long-term investment plan.

Thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

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 were first issued on February 22, 2008, and are designed for investors who meet certain administrative and service criteria and invest a minimum of $5 million. ETF Shares were first issued on December 17, 2007, and first offered to the public on December 21, 2007. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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

Mega Cap 300 Index Fund

in capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $11,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

During the period ended August 31, 2008, the fund realized $2,255,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $490,000 of ordinary income available for distribution. The fund had available realized losses of $673,000 to offset future net capital gains through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $149,161,000. Net unrealized depreciation of investment securities for tax purposes was $7,980,000, consisting of unrealized gains of $2,002,000 on securities that had risen in value since their purchase and $9,982,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended August 31, 2008, the fund purchased $195,778,000 of investment securities and sold $48,251,000 of investment securities, other than temporary cash investments.

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

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 were first issued on April 3, 2008, and are designed for investors who meet certain administrative and service criteria and invest a minimum of $5 million. ETF Shares were first issued on December 17, 2007, and first offered to the public on December 21, 2007. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

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

Mega Cap 300 Growth Index Fund

capital contributions to Vanguard. At August 31, 2008, the fund had contributed capital of $20,000 to Vanguard (included in Other Assets), representing 0.01% 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.

During the period ended August 31, 2008, the fund realized $484,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at August 31, 2008, the fund had $464,000 of ordinary income available for distribution. The fund had available realized losses of $551,000 to offset future net capital gains through August 31, 2017.

At August 31, 2008, the cost of investment securities for tax purposes was $259,580,000. Net unrealized depreciation of investment securities for tax purposes was $1,597,000, consisting of unrealized gains of $7,670,000 on securities that had risen in value since their purchase and $9,267,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended August 31, 2008, the fund purchased $274,486,000 of investment securities and sold $15,249,000 of investment securities, other than temporary cash investments.

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

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard World Funds and the Shareholders of Vanguard Mega Cap 300 Index Fund, Vanguard Mega Cap 300 Growth Index Fund and Vanguard Mega Cap 300 Value Index Fund:

In our opinion, the accompanying statements of net assets, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Mega Cap 300 Index Fund, Vanguard Mega Cap 300 Growth Index Fund and Vanguard Mega Cap 300 Value Index Fund (the “Funds”) at August 31, 2008, the results of each of their operations, the changes in each of their net assets and the financial highlights for the period December 17, 2007 (commencement of operations) through August 31, 2008, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities at August 31, 2008 by correspondence with the custodian and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

About Your Fund’s Expenses

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

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

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

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. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

1 The table does not include data for fund share classes with less than six months of history.

2 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: 0.08% for the Mega Cap 300 Index Fund Institutional Shares and 0.13% for the ETF Shares; 0.13% for the Mega Cap 300 Growth Index Fund ETF Shares; and 0.13% for the Mega Cap 300 Value Index Fund 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.

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard Mega Cap 300 Index Fund, Mega Cap 300 Growth Index Fund, and Mega Cap 300 Value Index Fund has renewed the funds’ investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group (QEG)—serves as investment advisor for the funds. The board determined that continuing the funds’ internalized management structure was in the best interests of the funds and their shareholders.

Nature, extent, and quality of services

The board considered the quality of the funds’ investment management services provided by QEG since the funds’ inceptions in 2007, and took into account the organizational depth and stability of the advisor. The board noted that Vanguard has been managing investments for more than 25 years. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985. Mr. Sauter has led QEG since 1987. QEG adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted approval of the advisory arrangement.

Investment performance

The board considered the funds’ performance since inception, including any periods of outperformance and underperformance of their target benchmarks and peer groups. The board concluded that the funds have performed in line with expectations, and that their results have been consistent with their investment strategies. Information about the funds’ performance can be found in the Performance Summary pages of this report.

Cost

The board does not conduct a profitability analysis of Vanguard, because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

The benefit of economies of scale

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