Your Fund’s Performance at a Glance

• Vanguard U.S. Growth Fund returned about 19% for the 12 months ended August 31, 2017. It trailed its benchmark’s 20.82% result and the 19.84% average return of its peers.

• Information technology stocks, which made up nearly half the portfolio’s assets at the end of the period, returned nearly 35%. The advisors’ heavy exposure to the sector and stock holdings within it also boosted relative performance.

• Financial, health care, and consumer discretionary stocks also made significant contributions to the fund’s return, although the advisors’ holdings hurt relative performance in the three sectors.

• The fund’s average annual return over the past ten years trailed that of its benchmark index but surpassed that of its peer group.

Chairman’s Perspective

Bill McNabb

Chairman and Chief Executive Officer

Dear Shareholder,

Since mid-August we’ve been reaching out to you about the proposals put forth by the Vanguard funds that, if approved, will enable us to manage the funds more efficiently and effectively. As the November deadline for voting approaches, I’d like to offer some perspective on a few of the proposals that I believe are important to the way Vanguard operates and manages your investments. I hope you consider this information and promptly cast your ballot.

Your biggest advocate

The main driver for this proxy solicitation is to ask all our fund shareholders to elect a full slate of trustees who oversee each U.S.-based Vanguard mutual fund. These trustees serve an important role, making sure your funds are managed in your best interests. This includes monitoring fund performance, approving advisory agreements, and ensuring that we’re keeping your investment costs as low as possible. Simply put, they are your biggest advocate.

Each trustee brings a variety of skills and professional experiences that contribute to the board’s strength and diversity. Of the 12 nominees, nine currently serve on the board, and three are new. If elected, the new board would include ten independent members, meaning they have no affiliation with Vanguard or the funds apart from any investments they may choose to make as private individuals.

These are the proposed new trustees:

• Sarah Bloom Raskin is a former member of the Federal Reserve Board of Governors and former deputy secretary of the U.S. Treasury Department. She is an expert in cybersecurity—a critically important issue at Vanguard, as we place a premium on protecting clients’ assets and sensitive data.

• Deanna Mulligan is chief executive officer of The Guardian Life Insurance Company of America. It’s rare to find a CEO such as Deanna who leads a company with a mutual ownership structure similar to Vanguard’s.

• Tim Buckley is president and a director of Vanguard and will succeed me in January as CEO. (I’ll remain chairman for a period to be determined by the board.) I interviewed Tim when he applied for his first job here in 1991 and again when he was graduating from Harvard Business School. I was thrilled he picked Vanguard as a place to build his career, and I’ve been delighted to see him take on several leadership positions, including as head of our Retail Investor Group, chief information officer, and chief investment officer. I can think of no one better prepared to succeed me.

Russell 2000 Index (Small-caps)	14.91	7.67	13.15

Citigroup Three-Month U.S. Treasury Bill Index	0.58	0.25	0.16

CPI
Consumer Price Index	1.94%	1.06%	1.28%

Vanguard believes that diversity of thought, background, and experience, as well as diversity of personal characteristics, meaningfully contributes to the board’s ability to effectively serve shareholders. If Sarah and Deanna are elected, women will account for 40% of the board’s independent trustees.

I should note that even as Vanguard is nominating three new board members, we’re saying goodbye to trustee Rajiv Gupta. Rajiv was a legendary CEO of Rohm and Haas Co., and Vanguard and our clients have benefited greatly from his expertise. I wish him a happy retirement.

Summarizing the proposals

Among the trustees’ leading responsibilities is overseeing the funds’ internal and external investment advisory agreements. The trustees, in consultation with our Global Investment Committee and our Portfolio Review Department, choose the investment advisors that manage client assets. Over decades, we have built a strong track record of picking advisors whose portfolio management strategies have served clients well.

Two proposals in the proxy focus on this oversight responsibility. Shareholders of 48 Vanguard funds have already voted to allow the board to make external advisor changes without obtaining prior shareholder approval. The new proposals would extend that policy across our entire U.S.-based fund lineup and expand it to include internal advisory agreements with Vanguard subsidiaries. Eliminating the need for shareholder approval removes a step that is costly and time-consuming if done frequently or on an individual fund basis. Although there are no current plans to employ the policy on any Vanguard-managed funds, standardizing it enables the trustees to retain an advisory firm to diversify a fund’s management team or ensure management continuity should a contingency arise.

I also encourage shareholders of several specific Vanguard index funds to read the proxy proposals that affect those funds. One proposal would change the investment objective of Vanguard REIT Index Fund and Vanguard Variable Insurance Fund REIT Index Portfolio to include real estate-related securities, aligning the funds with updated industry-sector classification methodology. Another proposal seeks to change the diversification status of the REIT Index Fund to enable it to better track its benchmark. Finally, we seek your approval of the Funds’ Service Agreement for Vanguard Institutional Index Fund and Vanguard Institutional Total Stock Market Index Fund. If approved, this arrangement would then be standardized across Vanguard’s entire publicly available U.S. mutual fund lineup. It should also reduce costs and minimum initial investment requirements in select share classes.

At the ballot box

We hope you’ll make it a priority to cast your ballot. We want to avoid the added time and cost of soliciting sufficient votes should we not obtain a quorum by the shareholder meeting on November 15, when voting concludes. Ultimately, we believe the proposals I’ve discussed are in your best interest as Vanguard fund shareholders, and the trustees recommend that you vote in favor of them.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

Chairman and Chief Executive Officer

Advisors’ Report

For the 12 months ended August 31, 2017, Vanguard U.S. Growth Fund returned about 19%. It trailed its benchmark, the Russell 1000 Growth Index, and the average return of its peers. Your fund is managed by five advisors. The use of multiple independent advisors enhances the fund’s diversification by providing exposure to distinct yet complementary investment approaches. It is not uncommon for different advisors to have different views about individual securities or the broader investment environment.

The table on page 12 presents the advisors, the percentage and amount of fund assets that each manages, and brief descriptions of their investment strategies. Each advisor has also prepared a discussion of the investment environment during the fiscal year and of how the portfolio’s positioning reflects this assessment. These reports were prepared on September 21, 2017.

As you would expect from our fundamental, bottom-up approach, stock selection is the primary driver of the portfolio’s performance.

TripAdvisor was the largest detractor from performance during the period because of its continued struggles in monetizing its hotel offerings and the underwhelming reviews of its mobile application. The company’s monetization plans have been executed more slowly than investors might have expected or hoped. But we still believe that the company has an undervalued asset of 400 million travelers interested in reviews, hotels, restaurants, and activities and that this asset is worth more than recognized at the current depressed valuation.

The top contributor was PayPal Holdings. PayPal has increasing business momentum and sees significant growth in total payment volume and active users. Venmo, PayPal’s peer-to-peer payment offering, has grown significantly, with $8 billion in transaction volume during the second quarter of 2017, up 103% year over year. We believe that PayPal’s core payment product will continue to perform as it expands its reach into physical merchants via Venmo and infrastructure offerings via Braintree.

Regardless of policy outcomes or macro-investor confidence, we remain consistent in our long-term investment philosophy: We want to own what we view as strong secular-growth companies with solid

business models and competitive positions that we believe can grow market share and have the potential to deliver shareholder value in a variety of market environments.

Portfolio Manager:

Andrew J. Shilling, CFA, Senior Managing Director

We aim for our portion of the fund to outperform growth benchmarks and, in the longer term, the broader market. We employ proprietary fundamental research and a rigorous valuation discipline to invest in large-capitalization companies with attractive growth characteristics.

Our investment approach is based on identifying companies with a clear competitive advantage that will enable them to sustain above-average growth.

Weak security selection in the industrial, consumer discretionary, and information technology sectors weighed on our portion of the fund over the last 12 months. Our selection within health care and financials also detracted from relative results. Our selection was stronger in consumer staples and real estate, helping to partially offset negative performance. Overweight exposure to information technology and underweight exposure to consumer staples (a fallout of our bottom-up stock selection) also aided performance.

The largest detractors from relative performance included Uber Technologies, a privately held transportation and ride-sharing company; Under Armour, a maker of athletic apparel; and O’Reilly Automotive, a parts retailer.

Netflix, a video-streaming company, was the leading contributor during the period. Other contributors included Alibaba, a Chinese e-commerce company, and ServiceNow, a provider of cloud-based services.

At the period’s close, we were most overweight in information technology, financials, and industrials. We reduced our exposure to consumer discretionary, where we are now underweight. We also remained underweight in materials, health care, and consumer staples as of the end of the period.

In this environment of moderate global growth and elevated uncertainty, we have maintained the portfolio’s exposure to secular trends and long-cycle growth. We believe these durable growth drivers will yield attractive relative returns during a challenging period for investors. We remain true to our process, seeking to invest in companies with competitive advantages, strong balance sheets, experienced and proven management, and the ability to sustain above-average growth.

While large-cap growth stocks advanced significantly over the year, the impact of style factors on our portfolio was largely neutral. Our higher growth bias, and resulting lower dividend yield exposure, was a tailwind, while our emphasis on companies with more durable business models was a headwind as companies with more volatile fundamentals outperformed.

Stock selection in consumer discretionary detracted from performance, in part because of positions in O’Reilly Automotive, Chipotle Mexican Grill, and Starbucks. O’Reilly Automotive was the top detractor in the sector because of weaker-than-expected sales and investor concerns about online competition potentially disrupting the aftermarket auto parts industry. Other notable detractors included grocery retailer Kroger and Cerner, a health care technology company. In addition, not owning Apple, the largest position in the benchmark, detracted meaningfully from relative returns.

Top contributors were software company Adobe Systems and health insurer UnitedHealth Group. Adobe reported strong financial results driven by its dominance in creative software. UnitedHealth was a beneficiary of the secular shift to managed care and value-based medicine. Other top contributors were information technology holdings Red Hat, Mastercard, and Microsoft.

As bottom-up, fundamental stock pickers, we maintain our focus on identifying businesses with idiosyncratic growth drivers that should power through a variety of economic or market scenarios and whose stocks present attractive risk/ reward opportunities. We believe that if we can identify and invest in high-quality companies with more durable growth opportunities than the market expects, investors in the stocks of those companies should be rewarded.

The unconventional U.S. presidential election and the new administration’s shaky start contributed to market volatility during the period. The initial favorable

market response to the election reflected anticipation of lower corporate tax rates, a less onerous regulatory environment, and increased spending on infrastructure. With legislative accomplishments elusive and factionalism impeding cooperation, market expectations moderated. Solid U.S. economic fundamentals included moderate GDP expansion, robust employment, and accelerating corporate profit growth.

Technology holdings were strong contributors to performance. Apple’s strength reflected the continued proliferation of its platform across the mobile phone, tablet, and personal computer landscape as well as the financial power related to Apple’s attractive margin profile regarding the profitability of its hardware products. Alibaba, with its dominant market share in important Chinese online businesses, saw significant revenue synergies and deeper engagement of buyers, merchants, advertisers, and cloud customers. Graphics chipmaker Nvidia benefited from its strength in key high-growth markets where developers have coalesced around its architecture and platform. Tencent gained from its dominant position in China’s online gaming and instant messaging markets and its advertising and payment service efforts.

In consumer discretionary, Netflix posted strong subscriber growth and international profits. Tesla rose on the introduction of its lower-cost electric vehicle, which targets the mainstream automotive market.

Health care holdings advanced but lagged the benchmark sector. Alexion Pharmaceuticals declined on news of an investigation into its sales practices and management shakeups. Allergan experienced challenges as it transitions to a future more dependent on volume growth than drug price increases. Shire was hurt by increased competition for its hemophilia drugs.

The U.S. market offers great long-term growth opportunities. A small number of outstanding growth companies in America are driving innovation and changing the world. In our view, their valuations continue to vastly underestimate their future potential. We are obsessed with capturing the long-term asymmetry of the U.S. equity market.

Notable contributors to performance included Tesla, which delivered its first mass-market Model 3 electric cars in July; Wayfair, the online furnishing company, which accelerated revenue growth as investments in distribution took hold; Netflix, which added subscribers as it invested heavily in original content; and Vertex Pharmaceuticals, which announced excellent clinical trial results for its cystic fibrosis drugs.

Among the main detractors were TripAdvisor, Under Armour, and Now, the global industrial distributor. TripAdvisor has struggled to expand from just search and price comparison to include direct booking. We continue to monitor progress and consider the growth potential of this bold move to change the business; other holdings have benefited from similarly aggressive strategic shifts in the past.

We focus on finding and holding exceptional growth companies, as defined by their culture, growth opportunity, and competitive edge. Competition for capital in the portfolio remains high; turnover is very low. We are, however, sufficiently excited by HEICO (generic aircraft parts), Redfin (web-based realty agent), and Shopify (innovative e-commerce platform) to have added them to the portfolio. Funding came from the complete sales of M&T Bank, Harley-Davidson, and Bristol-Myers Squibb.

U.S. Growth Fund

Notes to Financial Statements

Vanguard U.S. Growth Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

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

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

U.S. Growth Fund

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

During the year ended August 31, 2017, the fund’s average investments in long and short futures contracts represented 2% and 0% of net assets, respectively, based on the average of the notional amounts at each quarter-end during the period.

4. Repurchase Agreements: The fund enters into repurchase agreements with institutional counterparties. Securities pledged as collateral to the fund under repurchase agreements are held by a custodian bank until the agreements mature, and in the absence of a default, such collateral cannot be repledged, resold, or rehypothecated. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. The fund further mitigates its counterparty risk by entering into repurchase agreements only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master repurchase agreements with its counterparties. The master repurchase agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any repurchase agreements with that counterparty, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund. Such action may be subject to legal proceedings, which may delay or limit the disposition of collateral.

5. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2014–2017), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

U.S. Growth Fund

8. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

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

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

B. The investment advisory firms Jackson Square Partners, LLC, Wellington Management Company LLP, William Blair Investment Management, LLC, Jennison Associates LLC, and Baillie Gifford Overseas 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 Jackson Square Partners, LLC, Wellington Management Company LLP, and Jennison Associates LLC are subject to quarterly adjustments based on performance relative to the Russell 1000 Growth Index for the preceding three years. The basic fee of William Blair Investment Management, LLC, is subject to quarterly adjustments based on performance relative to the Russell 1000 Growth Index for the preceding five years. The basic fee of Baillie Gifford Overseas Ltd. is subject to quarterly adjustments based on performance relative to the S&P 500 Index for the preceding three years.

Vanguard manages the cash reserves of the fund as described below.

For the year ended August 31, 2017, the aggregate investment advisory fee represented an effective annual basic rate of 0.17% of the fund’s average net assets, before a net decrease of $553,000 (0.01%) based on performance.

U.S. Growth Fund

approved by the board of trustees. Vanguard does not require reimbursement in the current period for certain costs of operations (such as deferred compensation/benefits and risk/insurance costs); the fund’s liability for these costs of operations is included in Payables to Vanguard on the Statement of Net Assets.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $496,000, representing 0.01% of the fund’s net assets and 0.20% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

D. The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. For the year ended August 31, 2017, these arrangements reduced the fund’s expenses by $212,000 (an annual rate of 0.00% of average net assets).

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

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including 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). Any investments valued with significant unobservable inputs are
noted on the Statement of Net Assets.

The following table summarizes the market value of the fund’s investments as of August 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	7,462,256	34,976	2,715
Preferred Stocks	—	—	107,415
Temporary Cash Investments	286,634	29,085	—
Futures Contracts—Assets¹	1,458	—	—
Total	7,750,348	64,061	110,130
1 Represents variation margin on the last day of the reporting period.

The determination of Level 3 fair value measurements is governed by documented policies and procedures adopted by the board of trustees. The board has designated a pricing review committee, as an agent of the board, to ensure the timely analysis and valuation of Level 3 securities held by the fund in accordance with established policies and procedures. The pricing review committee employs various methods for calibrating valuation approaches, including a regular review of key inputs and assumptions, transactional back-testing or disposition analysis, and reviews of any related market activity. All valuation decisions made by the pricing review committee are reported to the board on a quarterly basis for review and ratification. The board reviews the adequacy of the fair value measurement policies and procedures in place on an annual basis.

U.S. Growth Fund

The following table summarizes changes in investments valued based on Level 3 inputs during the year ended August 31, 2017. Transfers into or out of Level 3 are recognized based on values as of the date of transfer.


	Investments	Investments

Net change in unrealized appreciation (depreciation) from investments still held as of August 31, 2017 was ($8,412,000).

The following table provides quantitative information about the significant unobservable inputs used in fair value measurement as of August 31, 2017:


	Fair Value
	at 8/31/2017			Amount or Range/

		Transaction with
		Uncertainty Discount
			Uncertainty Discount	15%

1 During the period ended August 31, 2017, the valuation technique was changed from Comparable Companies to Recent Market Transaction. This was considered to be a more relevant measure of fair value for this investment.

Significant increases or decreases in the significant unobservable inputs used in the fair value measurement of the portfolio’s Level 3 securities, in isolation, could result in a significantly higher or lower fair value measurement.

F. 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.

U.S. Growth Fund

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 $1,925,000 from undistributed net investment income, and $18,975,000 from accumulated net realized gains to paid-in capital.

For tax purposes, at August 31, 2017, the fund had $30,691,000 of ordinary income and $282,078,000 of long-term capital gains available for distribution.

At August 31, 2017, the cost of investment securities for tax purposes was $5,130,201,000. Net unrealized appreciation of investment securities for tax purposes was $2,792,880,000, consisting of unrealized gains of $2,920,859,000 on securities that had risen in value since their purchase and $127,979,000 in unrealized losses on securities that had fallen in value since their purchase.

G. During the year ended August 31, 2017, the fund purchased $1,853,135,000 of investment securities and sold $2,113,031,000 of investment securities, other than temporary cash investments.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard World Fund 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 (constituting a separate portfolio of Vanguard World Fund, hereafter referred to as the “Fund”) as of August 31, 2017, 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 as of August 31, 2017 by correspondence with the custodians and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Special 2017 tax information (unaudited) for Vanguard U.S. Growth Fund

This information for the fiscal year ended August 31, 2017, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $89,542,000 as capital gain dividends (20% rate gain distributions) to shareholders during the fiscal year.

The fund distributed $31,445,000 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.

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.


Average Annual Total Returns: U.S. Growth Fund Investor Shares
Periods Ended August 31, 2017
	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	19.24%	15.70%	8.62%

About Your Fund’s Expenses

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

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

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

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

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

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

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

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

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


Six Months Ended August 31, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
U.S. Growth Fund	2/28/2017	8/31/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,138.38	$2.37
Admiral Shares	1,000.00	1,139.33	1.67
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.99	$2.24
Admiral Shares	1,000.00	1,023.64	1.58

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 0.31% 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 (184/365).

Glossary

30-Day SEC Yield. A fund’s 30-day SEC yield is derived using a formula specified by the U.S. Securities and Exchange Commission. Under the formula, data related to the fund’s security holdings in the previous 30 days are used to calculate the fund’s hypothetical net income for that period, which is then annualized and divided by the fund’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s income is based on its current market yield to maturity (for bonds), its actual income (for asset-backed securities), or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the fund’s actual experience. As a result, the fund’s income distributions may be higher or lower than implied by the SEC yield.

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

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

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

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

Expense Ratio. A fund’s total annual operating expenses expressed as a percentage of the fund’s average net assets. The expense ratio includes management and administrative expenses, but does not include the transaction costs of buying and selling portfolio securities.

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

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

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

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share.

For a fund, the weighted average price/book ratio of the stocks it holds.

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

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

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

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

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

The People Who Govern Your Fund

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

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 195 Vanguard funds.

Information for each trustee and executive officer of the fund appears below. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.

Your Fund’s Performance at a Glance

• Amid stronger and more synchronized global growth, Vanguard International Growth Fund returned more than 28% for the 12 months ended August 31, 2017. That result was significantly better than its benchmark’s and the average return of its peers.

• The fund’s advisors added value in every region. Among emerging markets, stock selection in and an overweighting of China made that country the fund’s largest relative contributor.

• In Europe, positioning in Italy, the Netherlands, and the United Kingdom helped the most.

• In the Pacific region, a boost from the fund’s positioning in Japan was more than offset by weak selection in other countries, particularly South Korea.

• The fund outperformed its benchmark in a majority of sectors, but the biggest contributors were consumer discretionary and information technology, with each adding nearly 4 percentage points to the fund’s relative return.

Advisors’ Report

For the 12 months ended August 31, 2017, Vanguard International Growth Fund returned 28.43% for Investor Shares and 28.57% for Admiral Shares. Those results were well ahead of the return of its benchmark index (+18.88%) and the average return of peer funds (+17.59%). Your fund is managed by two independent advisors, a strategy that enhances the fund’s diversification by providing exposure to distinct yet complementary investment approaches. It is not uncommon for advisors to have different views about individual securities or the broader investment environment.

The advisors, the amount and percentage of fund assets each manages, and brief descriptions of their investment strategies are presented in the table below. The advisors have also prepared a discussion of the investment environment that existed during the fiscal year and of how the portfolio’s positioning reflects this assessment. These comments were prepared on September 25, 2017.

We invest in companies that we believe can grow significantly faster than the market for many years, possibly decades. These opportunities are quite rare, and owning these companies requires patience. But we think it pays to back our convictions, so our portion of the portfolio has become a little more concentrated over the last 12 months. We need to be supportive to long-term shareholders and encourage great growth-oriented companies to put long-term goals before the market’s toxic obsession with short-term targets.

A new breed of company has emerged in recent years that has little need of capital and that benefits from the effects of having a large network. In Tencent, Alibaba, and Amazon.com, we own companies that exemplify these traits and are now capable of dominating across different parts of the economy. Although these companies have contributed strongly to returns over many years, we believe that the prospects for patient shareholders remain fantastic.

One area we are particularly excited about is Chinese education. The one-child policy introduced in 1979 led to “4-2-1” family structures, with four grandparents, two parents, and a child. As a result, families invest heavily in their children’s education, to increase the chances of admission to universities and, ultimately, of finding a good job. TAL Education and New Oriental are two education providers that have been growing quickly and have contributed to returns. We believe these companies can continue to grow significantly faster than the market over the long term as both expand into new tier-two cities and beyond their core offering.

The notable detractor over the last 12 months was Banco Popular, as Santander acquired the Spanish bank in June for a nominal sum of €1. We have owned Popular since 2013, attracted by its small to medium-sized business lending franchise, a strong culture, and a consolidating Spanish banking industry. Since that time, the small to medium enterprise business has proved its worth, but rising debt levels and management changes have taken their toll.

In the weeks leading up to the bank’s sale, we were aware of the increasing challenges it faced, but we concluded that the probability of a good outcome remained large enough for us to retain a small holding. Although misplaced on this occasion, this focus on the

upside and acceptance that things can go wrong is an integral part of our investment approach.

One of the great advantages of long-term investing is that you need only a handful of new ideas to complement your existing holdings. Over the past year, the only new purchases in our portfolio have been Nidec, a Japanese electric motor company, and Delivery Hero, a German online food delivery company. We have also added to existing holdings, such as car manufacturers Ferrari and Tesla, Swedish bank Svenska Handelsbanken, and Dutch semiconductor company ASML. These additions were funded partly by the sale of holdings in Norwegian media company Schibsted and British life insurer Prudential. Several of the companies we held found buyers, including ARM, Syngenta, Mobileye, and Skyscanner.

Portfolio Manager:

Simon Webber, CFA

International equities enjoyed one of their strongest performance periods in years, against a supportive backdrop. The pace of economic growth improved in a majority of European and Asian economies, and monetary policy remained accommodative. Corporate earnings growth momentum has been broadening across regions and sectors in 2017, and that, along with

strengthening international currency markets, bodes well for prolonged better performance by international equities.

Within the portfolio, technology contributed most strongly to results, helped by an overweighting of the sector and stock choices within it. Our consumer and health care holdings also performed well, while our industrial ones detracted.

Among our tech holdings, the growth over this year of Chinese e-commerce platform Alibaba has been exceptional for a company of its size. Alibaba has delivered a succession of extremely strong results, most recently showcasing the strength of its underlying business model in delivering year-over-year revenue growth of 56%. The company’s scale, reach, and differentiation continue to drive greater earnings growth than the market expects. Although e-commerce has historically been its core, Alibaba is increasingly using its scale to expand into wider markets such as logistics, cloud-computing platforms, online video, and financial payments.

Our weakest holding was Germany’s GEA Group. The company, which supplies manufacturing equipment to the food and dairy industries, has been hurt by weaker capital investment plans by its customers and cost overruns from the implementation of a new IT system. Although management credibility has clearly been damaged, we believe that

much of the shortfall is due to cyclical issues, and we still see plenty of scope for management to improve profitability. We continue to engage with management and monitor the holding closely.

We see a number of structural trends, including online disruption and the energy transition, as important to the outlook for equities. Regarding the first trend, social media and online platforms are becoming disruptive to the profit pool of a growing list of industries. Retail, traditional media, and distribution businesses are among them, and we remain cautious about any traditional business that is not staying well-invested in technology to fend off the new competition.

Regarding the energy transition, a powerful combination is coming together of truly competitive renewable energy, improving battery-storage costs, and compelling electric powertrain vehicle products. This is set to transform the energy and automotive industries over the next two decades. There is now a viable path toward decarbonizing the energy and transportation industries, and we do not expect the transition to be linear. We believe our portfolio is well-positioned in companies that will grow faster than the market expects, as they supply the products and services needed to make this energy transition happen.

Overall, we believe that innovation is at the heart of sustainability. For companies to make their earnings more durable over the long term, they will require elements of innovative optimization (doing the same things better) or innovative transformation (changing existing paradigms) or both. We believe that well-managed companies with cultures that support ongoing innovation, performance, and accountability to their stakeholders will be best-placed to deliver outsized growth independent of the economic cycle.

International Growth Fund

Notes to Financial Statements

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

3. Futures and Forward Currency Contracts: The fund uses index futures contracts to a limited extent, with the objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing

International Growth Fund

brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract.

The fund enters 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 fund’s risks in using these contracts include movement in the values of the foreign currencies relative to the U.S. dollar and the ability of the counterparties to fulfill their obligations under the contracts. The fund mitigates its counterparty risk by entering into forward currency contracts only with a diverse group of prequalified counterparties, monitoring their financial strength, entering into master netting arrangements with its counterparties, and requiring its counterparties to transfer collateral as security for their performance. In the absence of a default, the collateral pledged or received by the fund cannot be repledged, resold, or rehypothecated. The master netting arrangements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate the forward currency contracts, determine the net amount owed by either party in accordance with its master netting arrangements, and sell or retain any collateral held up to the net amount owed to the fund under the master netting arrangements. The forward currency contracts contain provisions whereby a counterparty may terminate open contracts if the fund’s net assets decline below a certain level, triggering a payment by the fund if the fund is in a net liability position at the time of the termination. The payment amount would be reduced by any collateral the fund has pledged. Any assets pledged as collateral for open contracts are noted in the Statement of Net Assets. The value of collateral received or pledged is compared daily to the value of the forward currency contracts exposure with each counterparty, and any difference, if in excess of a specified minimum transfer amount, is adjusted and settled within two business days.

Futures contracts are valued at their quoted daily settlement prices. Forward currency contracts are valued at their quoted daily prices obtained from an independent third party, adjusted for currency risk based on the expiration date of each contract. The notional amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized gains (losses) on futures or forward currency contracts.

During the year ended August 31, 2017, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on the average of the notional amounts at each quarter-end during the period. The fund’s average investment in forward currency contracts represented 4% of net assets, based on the average of the notional amounts at each quarter-end during the period.

4. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2014–2017), 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. Securities Lending: To earn additional income, the fund lends its securities to qualified institutional borrowers. Security loans are subject to termination by the fund at any time, and are required to be secured at all times by collateral in an amount at least equal to the market

International Growth Fund

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

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

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

Withholding taxes on foreign dividends and capital gains have been provided for in accordance with the fund’s understanding of the applicable countries’ tax rules and rates. The fund has filed tax reclaims for previously withheld taxes on dividends earned in certain European Union countries. These filings are subject to various administrative and judicial proceedings within these countries. Such tax reclaims received during the year, if any, are included in dividend income. No other amounts for additional tax reclaims are reflected in the financial statements due to the uncertainty as to the ultimate resolution of proceedings, the likelihood of receipt of these reclaims, and the potential timing of payment.

International Growth Fund

B. The investment advisory firms Baillie Gifford Overseas Ltd. and Schroder Investment Management North America Inc. 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 Baillie Gifford Overseas Ltd. and Schroder Investment Management North America Inc. are subject to quarterly adjustments based on performance relative to the MSCI All Country World Index ex USA for the preceding three years. Vanguard manages the cash reserves of the fund as described below.

For the year ended August 31, 2017, the aggregate investment advisory fee represented an effective annual basic rate of 0.14% of the fund’s average net assets, before an increase of $6,650,000 (0.03%) based on performance.

C. In accordance with the terms of a Funds’ Service Agreement (the “FSA”) between Vanguard and the fund, Vanguard furnishes to the fund corporate management, administrative, marketing, distribution, and cash management services at Vanguard’s cost of operations (as defined by the FSA). These costs of operations are allocated to the fund based on methods and guidelines approved by the board of trustees. Vanguard does not require reimbursement in the current period for certain costs of operations (such as deferred compensation/benefits and risk/insurance costs); the fund’s liability for these costs of operations is included in Payables to Vanguard on the Statement of Net Assets.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $1,899,000, representing 0.01% of the fund’s net assets and 0.76% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

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

During the year ended August 31, 2017, the fund realized net foreign currency losses of $19,197,000, which decreased distributable net income for tax purposes; accordingly, such losses have been reclassified from accumulated net realized losses to undistributed net investment income.

For tax purposes, at August 31, 2017, the fund had $234,450,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $57,837,000 to offset taxable capital gains realized during the year ended August 31, 2017. At August 31, 2017, the fund had available capital losses totaling $538,520,000 to offset future net capital gains. Of this amount, $154,471,000 is subject to expiration on August 31, 2018. Capital losses of $384,049,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $20,820,710,000. Net unrealized appreciation of investment securities for tax purposes was $10,347,995,000, consisting of unrealized gains of $10,859,220,000 on securities that had risen in value since their purchase and $511,225,000 in unrealized losses on securities that had fallen in value since their purchase.

G. During the year ended August 31, 2017, the fund purchased $5,540,786,000 of investment securities and sold $3,703,656,000 of investment securities, other than temporary cash investments.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard World Fund 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 (constituting a separate portfolio of Vanguard World Fund, hereafter referred to as the “Fund”) as of August 31, 2017, 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 as of August 31, 2017 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Special 2017 tax information (unaudited) for Vanguard International Growth Fund

This information for the fiscal year ended August 31, 2017, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $264,162,000 of qualified dividend income to shareholders during the fiscal year.

The fund designates to shareholders foreign source income of $291,279,000 and foreign taxes paid of $26,659,000. Shareholders will receive more detailed information with their Form 1099-DIV in January 2018 to determine the calendar-year amounts to be included on their 2017 tax returns.

Your Fund’s After-Tax Returns

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income, using actual prior-year figures and estimates for 2017. (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.


Average Annual Total Returns: International Growth Fund Investor Shares
Periods Ended August 31, 2017
	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	28.43%	11.73%	4.50%
Returns After Taxes on Distributions	28.09	11.34	3.86
Returns After Taxes on Distributions and Sale of Fund Shares	16.31	9.29	3.47

About Your Fund’s Expenses

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


Six Months Ended August 31, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
International Growth Fund	2/28/2017	8/31/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,236.60	$2.54
Admiral Shares	1,000.00	1,237.35	1.80
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.94	$2.29
Admiral Shares	1,000.00	1,023.59	1.63

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 0.45% for Investor Shares and 0.32% 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 (184/365).

Glossary

Your Fund’s Performance at a Glance

• Vanguard FTSE Social Index Fund returned more than 17% for the 12 months ended August 31, 2017, closely tracking its target benchmark, the FTSE4Good US Select Index, but trailing the average return of its large-capitalization growth fund peers.

• In tracking its socially conscious benchmark, the fund tends to have greater exposure to sectors where companies are more likely to meet the index’s environmental, social, and governance criteria, such as the financial, technology, and health care sectors.

• Nine of ten sectors advanced. Of the fund’s two largest sectors, technology (+33%) posted the highest return and contributed most to performance. Financials returned 23%.

• Health care (+15%) and industrials (+21%) were the other top contributors. The only sector that lost ground was oil and gas, which returned –12%.

• The fund’s ten-year average annual return was in line with that of its benchmark and modestly trailed its large-cap growth fund peers.

Chairman’s Perspective

Bill McNabb

Chairman and Chief Executive Officer

Dear Shareholder,

Your biggest advocate

Each trustee brings a variety of skills and professional experiences that contribute to the board’s strength and diversity.

Of the 12 nominees, nine currently serve on the board, and three are new. If elected, the new board would include ten independent members, meaning they have no affiliation with Vanguard or the funds apart from any investments they may choose to make as private individuals.

These are the proposed new trustees:

FTSE Social Index Fund

Notes to Financial Statements

Vanguard FTSE Social Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and Institutional Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

FTSE Social Index Fund

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2014–2017), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

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

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

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

FTSE Social Index Fund

B. In accordance with the terms of a Funds’ Service Agreement (the “FSA”) between Vanguard and the fund, Vanguard furnishes to the fund investment advisory, corporate management, administrative, marketing, and distribution services at Vanguard’s cost of operations (as defined by the FSA). These costs of operations are allocated to the fund based on methods and guidelines approved by the board of trustees. Vanguard does not require reimbursement in the current period for certain costs of operations (such as deferred compensation/benefits and risk/insurance costs); the fund’s liability for these costs of operations is included in Payables to Vanguard on the Statement of Net Assets.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $211,000, 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 employees, respectively, of Vanguard.

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

The following table summarizes the market value of the fund’s investments as of August 31, 2017, based on the inputs used to value them:


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

At August 31, 2017, the fund had available capital losses totaling $26,035,000 to offset future net capital gains. Of this amount, $394,000 is subject to expiration on August 31, 2019. Capital losses of $25,641,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $2,520,166,000. Net unrealized appreciation of investment securities for tax purposes was $866,374,000, consisting of unrealized gains of $919,069,000 on securities that had risen in value since their purchase and $52,695,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $982,698,000 of investment securities and sold $308,823,000 of investment securities, other than temporary cash investments.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended August 31, 2017, such purchases and sales were $31,936,000 and $31,702,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard World Fund 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 (constituting a separate portfolio of Vanguard World Fund, hereafter referred to as the “Fund”) as of August 31, 2017, 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 as of August 31, 2017 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

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 Shares
Periods Ended August 31, 2017
	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	17.61%	16.12%	7.29%
Returns After Taxes on Distributions	17.15	15.70	6.99
Returns After Taxes on Distributions and Sale of Fund Shares	10.28	12.98	5.86

About Your Fund’s Expenses

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


Six Months Ended August 31, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
FTSE Social Index Fund	2/28/2017	8/31/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,063.71	$0.94
Institutional Shares	1,000.00	1,063.45	0.62
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,024.30	$0.92
Institutional Shares	1,000.00	1,024.60	0.61

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 0.18% for Investor Shares and 0.12% 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 (184/365).

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 Equity Index Group. 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. This evaluation included information provided to the board by Vanguard’s Portfolio Review Department, which is responsible for fund and advisor oversight and product management. The Portfolio Review Department met regularly with the advisor and made monthly presentations to the board during the fiscal year that directed the board’s focus to relevant information and topics.

The board, or an investment committee made up of board members, also received information throughout the year through advisor presentations. For each advisor presentation, the board was provided with letters and reports that included information about, among other things, the advisory firm and the advisor’s assessment of the investment environment, portfolio performance, and portfolio characteristics.

In addition, the board received monthly reports, which included a Market and Economic Report, a Fund Dashboard Monthly Summary, and a Fund Performance Report.

Prior to their meeting, the trustees were provided with a memo and materials that summarized the information they had received over the course of the year. They also 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 reviewed the quality of the fund’s investment management services over both the short and long term, and took into account the organizational depth and stability of the advisor. The board considered that Vanguard has been managing investments for more than three decades. The Equity Index Group 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 compared with its target index and peer group. The board concluded that the performance was such that the advisory arrangement should continue. Information about the fund’s most recent performance can be found in the Performance Summary section of this report.

Cost

The board concluded that the fund’s expense ratio was well below the average expense ratio charged by funds in its peer group and that the fund’s advisory expenses were also well below its peer-group average. Information about the fund’s expenses 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 at-cost arrangement with Vanguard ensures that the 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.

Your Fund’s Performance at a Glance

• For the 12 months ended August 31, 2017, returns for the Vanguard U.S. Sector Index Funds ranged from about –7.6% to almost 30%. All ten funds closely tracked their target indexes. Compared with their peer groups, results were mixed.

• Seven of the ten funds produced double-digit returns.

• Vanguard Information Technology Index Fund posted the best performance as strong corporate earnings in that sector continued to attract investors. Vanguard Financials Index Fund returned close to 25%, with rising interest rates and a more favorable operating environment likely to boost profitability.

and Performance tab. The ETF premium/discount analysis there shows the percentages of days on which the ETF Shares’ market price was above or below the NAV.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Consumer Discretionary Index Fund

for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard.

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, 2017, the fund realized $80,488,000 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, 2017, the fund had $6,924,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $48,045,000 to offset future net capital gains. Of this amount, $8,767,000 is subject to expiration dates; $7,274,000 may be used to offset future net capital gains through August 31, 2018, and $1,493,000 through August 31, 2019. Capital losses of $39,278,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $2,161,705,000. Net unrealized appreciation of investment securities for tax purposes was $260,754,000, consisting of unrealized gains of $462,756,000 on securities that had risen in value since their purchase and $202,002,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $453,842,000 of investment securities and sold $400,258,000 of investment securities, other than temporary cash investments. Purchases and sales include $272,889,000 and $266,441,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Consumer Staples Index Fund

lending agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $289,000, representing 0.01% of the fund’s net assets and 0.12% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

At August 31, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

Consumer Staples Index Fund

During the year ended August 31, 2017, the fund realized $213,746,000 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, 2017, the fund had $17,604,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $1,652,000 to offset taxable capital gains realized during the year ended August 31, 2017. At August 31, 2017, the fund had available capital losses totaling $22,758,000 to offset future net capital gains. Of this amount, $5,537,000 is subject to expiration on August 31, 2018. Capital losses of $17,221,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $4,108,760,000. Net unrealized appreciation of investment securities for tax purposes was $430,689,000, consisting of unrealized gains of $507,954,000 on securities that had risen in value since their purchase and $77,265,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $1,086,796,000 of investment securities and sold $798,960,000 of investment securities, other than temporary cash investments. Purchases and sales include $743,072,000 and $590,275,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Energy Index Fund

Notes to Financial Statements

Vanguard Energy Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Energy Index Fund

proceedings. While collateral mitigates counterparty risk, in the event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $282,000, representing 0.01% of the fund’s net assets and 0.11% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

At August 31, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

Energy Index Fund

During the year ended August 31, 2017, the fund realized $71,161,000 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, 2017, the fund had $47,244,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $636,582,000 to offset future net capital gains. Of this amount, $68,284,000 is subject to expiration dates; $37,585,000 may be used to offset future net capital gains through August 31, 2018, and $30,699,000 through August 31, 2019. Capital losses of $568,298,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $5,279,402,000. Net unrealized depreciation of investment securities for tax purposes was $1,066,142,000, consisting of unrealized gains of $89,532,000 on securities that had risen in value since their purchase and $1,155,674,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $961,802,000 of investment securities and sold $1,108,892,000 of investment securities, other than temporary cash investments. Purchases and sales include $408,958,000 and $414,680,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Financials Index Fund

represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $426,000, representing 0.01% of the fund’s net assets and 0.17% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

The following table summarizes the market value of the fund’s investments as of August 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	6,645,060	—	176
Temporary Cash Investments	3,030	—	—
Total	6,648,090	—	176

Financials Index Fund

During the year ended August 31, 2017, the fund realized $157,664,000 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, 2017, the fund had $28,769,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $163,496,000 to offset future net capital gains. Of this amount, $144,329,000 is subject to expiration dates; $76,963,000 may be used to offset future net capital gains through August 31, 2018, and $67,366,000 through August 31, 2019. Capital losses of $19,167,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $5,858,317,000. Net unrealized appreciation of investment securities for tax purposes was $789,949,000, consisting of unrealized gains of $859,000,000 on securities that had risen in value since their purchase and $69,051,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $2,797,439,000 of investment securities and sold $1,033,872,000 of investment securities, other than temporary cash investments. Purchases and sales include $2,258,542,000 and $786,590,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Health Care Index Fund

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $494,000, representing 0.01% of the fund’s net assets and 0.20% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

The following table summarizes the market value of the fund’s investments as of August 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	7,918,477	—	600
Temporary Cash Investments	24,517	—	—

Total	7,943,026	—	600
1 Represents variation margin on the last day of the reporting period.

Health Care Index Fund

During the year ended August 31, 2017, the fund realized $185,458,000 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, 2017, the fund had $20,775,000 of ordinary income available for distribution. The fund had available capital losses totaling $104,392,000 that may be carried forward indefinitely to offset future net capital gains.

At August 31, 2017, the cost of investment securities for tax purposes was $6,610,843,000. Net unrealized appreciation of investment securities for tax purposes was $1,332,751,000, consisting of unrealized gains of $1,611,819,000 on securities that had risen in value since their purchase and $279,068,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $1,324,423,000 of investment securities and sold $804,222,000 of investment securities, other than temporary cash investments. Purchases and sales include $931,635,000 and $512,168,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

During the year ended August 31, 2017, the fund’s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on the average of the notional amounts each quarter-end during the period. The fund had no open futures contracts at August 31, 2017.

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

experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $215,000, representing 0.01% of the fund’s net assets and 0.09% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

At August 31, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

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, 2017, the fund realized $128,911,000 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, 2017, the fund had $13,262,000 of ordinary income available for distribution.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Information Technology Index Fund

received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $943,000, representing 0.01% of the fund’s net assets and 0.38% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

At August 31, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

Information Technology Index Fund

During the year ended August 31, 2017, the fund realized $611,458,000 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, 2017, the fund had $38,361,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $118,467,000 to offset future net capital gains. Of this amount, $40,376,000 is subject to expiration dates; $20,048,000 may be used to offset future net capital gains through August 31, 2018, and $20,328,000 through August 31, 2019. Capital losses of $78,091,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards. Capital loss carryforwards of $7,582,000 expired on August 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At August 31, 2017, the cost of investment securities for tax purposes was $10,786,091,000. Net unrealized appreciation of investment securities for tax purposes was $4,820,938,000, consisting of unrealized gains of $4,995,491,000 on securities that had risen in value since their purchase and $174,553,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $4,464,202,000 of investment securities and sold $1,888,774,000 of investment securities, other than temporary cash investments. Purchases and sales include $3,283,381,000 and $1,162,433,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

At August 31, 2017, one shareholder was the record or beneficial owner of 31% of the fund’s net assets. If the shareholder were to redeem its investment in the fund, the redemption might result in an increase in the fund’s expense ratio.

G. Management has determined that no material events or transactions occurred subsequent to August 31, 2017, that would require recognition or disclosure in these financial statements.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

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

Materials Index Fund

the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $144,000, 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 employees, respectively, of Vanguard.

At August 31, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

Materials Index Fund

During the year ended August 31, 2017, the fund realized $144,644,000 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, 2017, the fund had $8,616,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $81,292,000 to offset future net capital gains. Of this amount, $39,290,000 is subject to expiration dates; $18,156,000 may be used to offset future net capital gains through August 31, 2018, and $21,134,000 through August 31, 2019.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

Futures contracts are valued at their quoted daily settlement prices. The notional amounts of the contracts are not recorded in the Statement of Assets and Liabilities. Fluctuations in the value of the contracts are recorded in the Statement of Assets and Liabilities 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).

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

101

Telecommunication Services Index Fund

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

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $89,000, 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 employees, respectively, of Vanguard.

During the year ended August 31, 2017, the fund realized $77,444,000 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, 2017, the fund had $11,464,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $11,726,000 to offset taxable capital gains realized during the year ended August 31, 2017. At August 31, 2017, the fund had available capital losses totaling $58,483,000 to offset future net capital gains. Of this amount, $37,793,000 is subject to expiration dates; $26,335,000 may be used to offset future net capital gains through August 31, 2018, and $11,458,000 through August 31, 2019. Capital losses of $20,690,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards. Capital loss carryforwards of $7,492,000 expired on August 31, 2017; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At August 31, 2017, the cost of investment securities for tax purposes was $1,587,027,000. Net unrealized depreciation of investment securities for tax purposes was $92,620,000, consisting of unrealized gains of $114,347,000 on securities that had risen in value since their purchase and $206,967,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $693,700,000 of investment securities and sold $766,530,000 of investment securities, other than temporary cash investments. Purchases and sales include $396,790,000 and $509,794,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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: ETF Shares and Admiral Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

During the year ended August 31, 2017, the fund’s average investments in long and short futures contracts each represented 0% of net assets, based on the average of notional amounts at each quarter-end during the period. The fund had no open futures contracts at August 31, 2017.

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

112

Utilities Index Fund

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. 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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $213,000, representing 0.01% of the fund’s net assets and 0.09% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

At August 31, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

113

Utilities Index Fund

During the year ended August 31, 2017, the fund realized $109,857,000 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, 2017, the fund had $21,692,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $15,553,000 to offset future net capital gains. Of this amount, $6,018,000 is subject to expiration dates; $2,655,000 may be used to offset future net capital gains through August 31, 2018, and $3,363,000 through August 31, 2019. Capital losses of $9,535,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $3,160,626,000. Net unrealized appreciation of investment securities for tax purposes was $375,929,000, consisting of unrealized gains of $455,447,000 on securities that had risen in value since their purchase and $79,518,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $853,525,000 of investment securities and sold $636,400,000 of investment securities, other than temporary cash investments. Purchases and sales include $599,691,000 and $505,261,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard World Fund and the Shareholders of Vanguard Consumer Discretionary Index Fund, Vanguard Consumer Staples Index Fund, Vanguard Energy Index Fund, Vanguard Financials Index Fund, Vanguard Health Care Index Fund, Vanguard Industrials Index Fund, Vanguard Information Technology Index Fund, Vanguard Materials Index Fund, Vanguard Telecommunication Services Index Fund and Vanguard Utilities Index Fund: In our opinion, the accompanying statement of assets and liabilities of Vanguard Telecommunication Services Index Fund and statements of net assets of Vanguard Consumer Discretionary Index Fund, Vanguard Consumer Staples Index Fund, Vanguard Energy Index Fund, Vanguard Financials Index Fund, Vanguard Health Care Index Fund, Vanguard Industrials Index Fund, Vanguard Information Technology Index Fund, Vanguard Materials Index Fund, Vanguard Telecommunication Services Index Fund and Vanguard Utilities Index Fund (constituting separate portfolios of Vanguard World Fund, hereafter referred to as the “Funds”) 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 the Funds as of August 31, 2017, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of August 31, 2017 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Special 2017 tax information (unaudited) for Vanguard U.S. Sector Index Funds

This information for the fiscal year ended August 31, 2017, is included pursuant to provisions of the Internal Revenue Code.

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

Your Fund’s After-Tax Returns

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income, using actual prior-year figures and estimates for 2017. (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 one share class 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

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. Further, the expenses do not include any purchase, redemption, or account service fees described in the fund prospectus. If such fees were applied to your account, your costs would be higher. Your fund does not carry a “sales load.” The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses 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 0.10% for the Consumer Discretionary Index Fund ETF Shares and 0.10% for the Admiral Shares; 0.10% for the Consumer
Staples Index Fund ETF Shares and 0.10% for the Admiral Shares; 0.10% for the Energy Index Fund ETF Shares and 0.10% for the Admiral
Shares; 0.10% for the Financials Index Fund ETF Shares and 0.10% for the Admiral Shares; 0.10% for the Health Care Index Fund ETF
Shares and 0.10% for the Admiral Shares; 0.10% for the Industrials Index Fund ETF Shares and 0.10% for the Admiral Shares; 0.10% for
the Information Technology Index Fund ETF Shares and 0.09% for the Admiral Shares; 0.10% for the Materials Index Fund ETF Shares and
0.10% for the Admiral Shares; 0.10% for the Telecommunication Services Index Fund ETF Shares and 0.10% for the Admiral Shares; 0.10%
for the Utilities Index Fund ETF Shares and 0.10% for the 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 (184/365).

Trustees Approve Advisory Arrangements

The board of trustees of Vanguard Consumer Discretionary Index Fund, Vanguard Consumer Staples Index Fund, Vanguard Energy Index Fund, Vanguard Financials Index Fund, Vanguard Health Care Index Fund, Vanguard Industrials Index Fund, Vanguard Information Technology Index Fund, Vanguard Materials Index Fund, Vanguard Telecommunication Services Index Fund, and Vanguard Utilities Index Fund has renewed each fund’s investment advisory arrangement with The Vanguard Group, Inc. (Vanguard), through its Equity Index Group. The board determined that continuing each fund’s internalized management structure was in the best interests of the fund and its shareholders.

In addition, the board received monthly reports, which included a Market and Economic Report, a Fund Dashboard Monthly Summary, and a Fund Performance Report.

Prior to their meeting, the trustees were provided with a memo and materials that summarized the information they had received over the course of the year. They also considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangements. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services

The board reviewed the quality of each fund’s investment management services over both the short and long term and took into account the organizational depth and stability of the advisor. The board considered that Vanguard has been managing investments for more than three decades. The Equity Index Group 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 each advisory arrangement.

Investment performance

The board considered the short- and long-term performance of each fund, including any periods of outperformance or underperformance compared with its target index and peer group. The board concluded that the performance was such that each advisory arrangement should continue. Information about each fund’s most recent performance can be found on the Performance Summary pages of this report.

Cost

The board concluded that each fund’s expense ratio was well below the average expense ratio charged by funds in its peer group and that each fund’s advisory expenses were also well below the peer-group average. Information about the funds’ expenses 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 each fund’s at-cost arrangement with Vanguard ensures that the funds will realize economies of scale as they grow, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangements 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. A fund’s total annual operating expenses expressed as a percentage of the fund’s average net assets. The expense ratio includes management administrative expenses, but does not include the transaction costs of buying and selling portfolio securities.

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

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

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

Your Fund’s Performance at a Glance

• ETF shares of Vanguard Extended Duration Treasury Index Fund returned –8.86% for the 12 months ended August 31, 2017. This result was a bit better than that of the fund’s benchmark index (–9.20%).

• The fund’s return trailed the average return of general U.S. Treasury securities because the broader Treasury market includes a wider range of maturities. Although Treasury prices fell across the maturity spectrum, longer-term Treasuries (a focus of the fund) fared worse than their shorter-term counterparts.

• Treasury prices dropped as markets grew more optimistic about economic growth prospects, even as inflation readings remained modest. The bonds’ price declines raised their yields. The 30-day SEC yield of the fund’s ETF Shares began the fiscal year at 2.28% and ended it at 2.77%.

Institutional Shares and Institutional Plus Shares are available to certain institutional investors who meet specific administrative, service, and account-size criteria. The Vanguard ETF® Shares shown are traded on the NYSE Arca exchange and are available only through brokers. The table provides ETF returns based on both the NYSE Arca market price and the net asset value for a share. U.S. Pat. Nos. 6,879,964; 7,337,138; 7,720,749; 7,925,573; 8,090,646; and 8,417,623.

For the ETF Shares, the market price is determined by the midpoint of the bid-offer spread as of the closing time of the New York Stock Exchange (generally 4 p.m., Eastern time). The net asset value is also determined as of the NYSE closing time. For more information about how the ETF Shares' market prices have compared with their net asset value, visit vanguard.com, select your ETF, and then select the Price and Performance tab. The ETF premium/discount analysis there shows the percentages of days on which the ETF Shares' market price was above or below the NAV.

Extended Duration Treasury Index Fund

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: ETF Shares, Institutional Shares, and Institutional Plus Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Institutional Shares and Institutional Plus Shares are designed for investors who meet certain administrative, service, 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. Bonds and temporary cash investments are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Securities for which market quotations are not readily available, or whose values have been affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (August 31, 2014–2017), 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. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread.

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

5. 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 assessed on capital share transactions are credited to paid-in capital.

Extended Duration Treasury Index Fund

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $102,000, 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 employees, respectively, 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, 2017, custodian fee offset arrangements reduced the fund’s expenses by $9,000 (an annual rate of 0.00% of average net assets).

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

The following table summarizes the market value of the fund’s investments as of August 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
U.S. Government and Agency Obligations	—	1,672,100	—
Temporary Cash Investments	198	—	—
Total	198	1,672,100	—

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

Extended Duration Treasury Index Fund

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, 2017, the fund realized $24,919,000 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 gains to paid-in capital.

For tax purposes, at August 31, 2017, the fund had $8,519,000 of ordinary income and $4,568,000 of long-term capital gains available for distribution.

At August 31, 2017, the cost of investment securities for tax purposes was $1,545,827,000. Net unrealized appreciation of investment securities for tax purposes was $126,471,000, consisting of unrealized gains of $129,463,000 on securities that had risen in value since their purchase and $2,992,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended August 31, 2017, the fund purchased $650,970,000 of investment securities and sold $408,227,000 of investment securities, other than temporary cash investments. Purchases and sales include $172,847,000 and $157,054,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

H. Management has determined that no material events or transactions occurred subsequent to August 31, 2017, that would require recognition or disclosure in these financial statements.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard World Fund 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 (constituting a separate portfolio of Vanguard World Fund, hereafter referred to as the “Fund”) as of August 31, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of August 31, 2017 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

About Your Fund’s Expenses

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


Six Months Ended August 31, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Extended Duration Treasury Index Fund	2/28/2017	8/31/2017	Period
Based on Actual Fund Return
ETF Shares	$1,000.00	$1,090.60	$0.37
Institutional Shares	1,000.00	1,090.66	0.32
Institutional Plus Shares	1,000.00	1,090.66	0.21
Based on Hypothetical 5% Yearly Return
ETF Shares	$1,000.00	$1,024.85	$0.36
Institutional Shares	1,000.00	1,024.90	0.31
Institutional Plus Shares	1,000.00	1,025.00	0.20

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 0.07% for ETF Shares, 0.06% for Institutional Shares, and 0.04% for Institutional Plus 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 (184/365).

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard Extended Duration Treasury Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. (Vanguard), through its Fixed Income Group. The board determined that continuing the fund’s internalized management structure was in the best interests of the fund and its shareholders.

In addition, the board received monthly reports, which included a Market and Economic Report, a Fund Dashboard Monthly Summary, and a Fund Performance Report.

Nature, extent, and quality of services

The board reviewed the quality of the fund’s investment management services over both the short and long term, and took into account the organizational depth and stability of the advisor. The board considered that Vanguard has been managing investments for more than three decades. The Fixed Income Group 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.

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.

Credit Quality. Credit-quality ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). U.S. Treasury, U.S. Agency, and U.S. Agency mortgage-backed securities appear under “U.S. Government.” Credit-quality ratings are obtained from Barclays and are from Moody’s, Fitch, and S&P. When ratings from all three agencies are used, the median rating is shown. When ratings from two of the agencies are used, the lower rating for each issue is shown. “Not Rated” is used to classify securities for which a rating is not available.

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.

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.

Institutional Shares are available to certain institutional investors who meet specific administrative, service, and account-size criteria. The
Vanguard ETF® Shares shown are traded on the NYSE Arca exchange and are available only through brokers. The table provides ETF
returns based on both the NYSE Arca market price and the net asset value for a share. U.S. Pat. Nos. 6,879,964; 7,337,138; 7,720,749;
7,925,573; 8,090,646; and 8,417,623.
For the ETF Shares, the market price is determined by the midpoint of the bid-offer spread as of the closing time of the New York Stock
Exchange (generally 4 p.m., Eastern time). The net asset value is also determined as of the NYSE closing time. For more information about
how the ETF Shares' market prices have compared with their net asset value, visit vanguard.com, select your ETF, and then select the
Price and Performance tab. The ETF premium/discount analysis there shows the percentages of days on which the ETF Shares' market
price was above or below the NAV.

Mega Cap Index Fund

Notes to Financial Statements

Vanguard Mega Cap 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: ETF Shares and Institutional Shares. ETF Shares are listed for trading on NYSE Arca; they can be purchased and sold through a broker. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria.

Mega Cap Index Fund

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

The fund had no borrowings outstanding at August 31, 2017, or at any time during the period then ended.

Mega Cap Index Fund

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At August 31, 2017, the fund had contributed to Vanguard capital in the amount of $89,000, 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 employees, respectively, of Vanguard.

The following table summarizes the market value of the fund’s investments as of August 31, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	1,360,410	—	—
Temporary Cash Investments	948	200	—

Mega Cap Index Fund

During the year ended August 31, 2017, the fund realized $54,527,000 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, 2017, the fund had $6,344,000 of ordinary income available for distribution. The fund used capital loss carryforwards of $4,369,000 to offset taxable capital gains realized during the year ended August 31, 2017. At August 31, 2017, the fund had available capital losses totaling $36,441,000 to offset future net capital gains. Of this amount, $18,779,000 is subject to expiration dates; $12,576,000 may be used to offset future net capital gains through August 31, 2018 and $6,203,000 through August 31, 2019. Capital losses of $17,662,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $926,610,000. Net unrealized appreciation of investment securities for tax purposes was $434,948,000, consisting of unrealized gains of $458,658,000 on securities that had risen in value since their purchase and $23,710,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $195,100,000 of investment securities and sold $179,418,000 of investment securities, other than temporary cash investments. Purchases and sales include $60,408,000 and $106,748,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Mega Cap Growth Index Fund

During the year ended August 31, 2017, the fund realized $91,675,000 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, 2017, the fund had $8,117,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $62,489,000 to offset future net capital gains. Of this amount, $4,562,000 is subject to expiration on August 31, 2019. Capital losses of $57,927,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $2,268,479,000. Net unrealized appreciation of investment securities for tax purposes was $906,701,000, consisting of unrealized gains of $947,172,000 on securities that had risen in value since their purchase and $40,471,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $826,069,000 of investment securities and sold $410,136,000 of investment securities, other than temporary cash investments. Purchases and sales include $565,410,000 and $187,480,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended August 31, 2017, such purchases and sales were $76,696,000 and $103,249,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

Mega Cap Value Index Fund

During the year ended August 31, 2017, the fund realized $38,219,000 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, 2017, the fund had $11,697,000 of ordinary income available for distribution. At August 31, 2017, the fund had available capital losses totaling $25,266,000 to offset future net capital gains. Of this amount, $4,326,000 is subject to expiration on August 31, 2019. Capital losses of $20,940,000 realized beginning in fiscal 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards.

At August 31, 2017, the cost of investment securities for tax purposes was $1,463,071,000. Net unrealized appreciation of investment securities for tax purposes was $375,268,000, consisting of unrealized gains of $412,749,000 on securities that had risen in value since their purchase and $37,481,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended August 31, 2017, the fund purchased $438,879,000 of investment securities and sold $290,803,000 of investment securities, other than temporary cash investments. Purchases and sales include $307,725,000 and $101,768,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

The fund purchased securities from and sold securities to other Vanguard funds or accounts managed by Vanguard or its affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended August 31, 2017, such purchases and sales were $43,725,000 and $35,301,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard World Fund and the Shareholders of Vanguard Mega Cap Index Fund, Vanguard Mega Cap Growth Index Fund and Vanguard Mega Cap 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 Index Fund, Vanguard Mega Cap Growth Index Fund and Vanguard Mega Cap Value Index Fund (constituting separate portfolios of Vanguard World Fund, hereafter referred to as the “Funds”) as of August 31, 2017, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of August 31, 2017 by correspondence with the custodian and brokers and by agreement to the underlying ownership records of the transfer agent, provide a reasonable basis for our opinion.

Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown.

About Your Fund’s Expenses

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


Six Months Ended August 31, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	2/28/2017	8/31/2017	Period
Based on Actual Fund Return
Mega Cap Index Fund
ETF Shares	$1,000.00	$1,060.70	$0.36
Institutional Shares	1,000.00	1,060.68	0.31
Mega Cap Growth Index Fund
ETF Shares	$1,000.00	$1,107.92	$0.37
Institutional Shares	1,000.00	1,107.99	0.32
Mega Cap Value Index Fund
ETF Shares	$1,000.00	$1,019.90	$0.36
Institutional Shares	1,000.00	1,019.94	0.31
Based on Hypothetical 5% Yearly Return
Mega Cap Index Fund
ETF Shares	$1,000.00	$1,024.85	$0.36
Institutional Shares	1,000.00	1,024.90	0.31
Mega Cap Growth Index Fund
ETF Shares	$1,000.00	$1,024.85	$0.36
Institutional Shares	1,000.00	1,024.90	0.31
Mega Cap Value Index Fund
ETF Shares	$1,000.00	$1,024.85	$0.36
Institutional Shares	1,000.00	1,024.90	0.31

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for
that period are: for the Mega Cap Index Fund, 0.07% for ETF Shares and 0.06% for Institutional Shares; for the Mega Cap Growth Index
Fund, 0.07% for ETF Shares and 0.06% for Institutional Shares; and for the Mega Cap Value Index Fund, 0.07% for ETF Shares and 0.06%
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 (184/365).

Trustees Approve Advisory Arrangements

The board of trustees of Vanguard Mega Cap Index Fund, Vanguard Mega Cap Growth Index Fund, and Vanguard Mega Cap Value Index Fund has renewed each fund’s investment advisory arrangement with The Vanguard Group, Inc. (Vanguard), through its Equity Index Group. The board determined that continuing each fund’s internalized management structure was in the best interests of the fund and its shareholders.

In addition, the board received monthly reports, which included a Market and Economic Report, a Fund Dashboard Monthly Summary, and a Fund Performance Report.

Prior to their meeting, the trustees were provided with a memo and materials that summarized the information they had received over the course of the year. They also considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangements. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services

The board reviewed the quality of each fund’s investment management services over both the short and long term, and took into account the organizational depth and stability of the advisor. The board considered that Vanguard has been managing investments for more than three decades. The Equity Index Group 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 each advisory arrangement.

Investment performance

Cost

The board concluded that each fund’s expense ratio was well below the average expense ratio charged by funds in its respective peer group. The board also concluded that the advisory expenses for the Mega Cap Index Fund and Mega Cap Growth Index Fund were well below the advisory expenses of funds in their peer groups, while the advisory expenses for the Mega Cap Value Index Fund were reasonable compared with the average advisory expenses for funds in its peer group. Information about the funds’ expenses 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 will consider whether to renew the advisory arrangements again after a one-year period.
