Your Fund’s Performance at a Glance

• Vanguard U.S. Growth Fund returned almost 5% for the six months ended February 28, 2017. It trailed the 9.15% return of its benchmark, the Russell 1000 Growth Index, and the 7.44% average return of its large-capitalization growth peers.

• The fund’s five advisors manage their portions of the portfolio separately, but all seek to hold the stocks of large, high-quality companies with long-term growth potential.

• Value stocks outperformed growth during the half-year, and small-cap stocks topped large- and mid-caps.

• Information technology stocks, which made up about 40% of the portfolio, added the most to the fund’s absolute return but lagged those contained in the benchmark. The advisors’ consumer discretionary, industrial, and health care stocks also recorded subpar returns versus their benchmark counterparts.

• The fund held stocks in 9 of 11 industry sectors at the period’s end; only consumer staples declined.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

More than a decade ago, a Vanguard client asked us to help improve its defined contribution retirement plan. New hires were participating in the plan at lower rates than in previous years, and the client wanted to reverse this trend. Another priority was to help more participants invest their retirement savings in balanced portfolios.

The overall goal of this longtime client: Give employees a better chance to achieve financial security in retirement.

Today, that plan automatically enrolls employees at a 5% contribution rate, puts them in a low-cost target-date fund that takes on less risk as they near retirement, and offers a comprehensive suite of advice services. On top of that, employees get an employer contribution of 5% and are eligible for a company match.

Because of this combination of attractive features and generous employer contributions, nearly all new hires now participate in the plan, 81% of plan participants invest their retirement savings in balanced portfolios, and 87% of participants meet or exceed Vanguard’s recommended total retirement savings target. (Vanguard generally recommends that retirement investors save 12%–15% of pay, including company matches.)

Changing the retirement landscape

Am I singling out an isolated Vanguard success story? Absolutely not.

Stories like these are becoming increasingly common with employer-based retirement plans, particularly among large and midsize companies. Solutions such as automatic enrollment, automatic contribution increases, and default investment in target-date funds are having a positive effect.

Insights from the relatively new discipline of behavioral finance have contributed to the advances. Simply put, retirement plans are making natural human inertia work for future retirees, rather than against them, by putting savings on autopilot as much as possible.

More than 60% of Vanguard participants are in plans with automatic enrollment, which has led to a big jump in participation. Today, more than four-fifths of eligible employees are saving for retirement, compared with only two-thirds ten years ago.

In addition, many plans have adopted automatic-escalation features, which increase plan contributions at regular intervals until a maximum level is reached or an employee opts out. Automatic increases are a crucial tool for boosting retirement savings rates.

The growing use of target-date funds is another enormous benefit. More than 70% of all participants in Vanguard plans invest at least part of their retirement savings in

these age-appropriate, diversified strategies. And nearly 50% of Vanguard participants are invested solely in a single target-date fund.

Consider a do-it-yourself autopilot

But what if you don’t have access to a world-class, employer-based retirement plan? Unfortunately, not everyone does, which is an important policy issue.

However, you can still put the features of these plans to work. For example, you can set up automatic contributions from your paycheck to an IRA. And you can adopt your own automatic escalation by investing any pay raises.

You can also take a page from top-quality retirement plans by considering a low-cost, globally diversified target-date fund. The beauty of this approach is that you don’t need to remember to rebalance your portfolio—the fund does it for you.

Of course, you can take a more active role in picking your own investments, and this can be a good choice for some. But keep in mind the lessons from successful employer-based plans: Busy workers, faced with a lot of competing priorities, are often best served by putting their retirement savings on autopilot.

Winning by default

In highlighting some recent successes in retirement savings, I don’t want to minimize the challenges we still face. We’re living in a slow-growth, uncertain world, and investment returns for both stocks and bonds could well be modest in the coming decade.

But I believe the innovations we’ve seen in the last ten years in many retirement plans—you might call it the “default revolution”—point the way toward a solution. And that even goes for people whose employers don’t have a world-class retirement plan.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Advisors’ Report

For the six months ended February 28, 2017, Vanguard U.S. Growth Fund returned nearly 5%. 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 10 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 half-year and of how the portfolio’s positioning reflects this assessment. These reports were prepared on March 16, 2017.

Wellington Management Company llp

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, information technology, and health care sectors weighed on our portion of the fund over the last six months. Choices in consumer discretionary also detracted from relative results. Our selection was stronger in real estate, helping to partially offset weakness elsewhere. An underweighted exposure to consumer staples and an overweighted allocation to information technology (a result of our bottom-up stock selection) further boosted results.

The largest detractors from relative performance included athletic apparel-maker Under Armour, medical equipment supplier Edwards Lifesciences, and energy and soft drink company Monster Beverage.

Netflix was the leading contributor. Other standouts included consumer electronics company Harman International Industries and technology products and services provider CDW.

At the period’s close, we were most overweighted in the information technology, financial, and industrial sectors. We reduced our exposure to consumer discretionary, where we now have an underweighted allocation. We also remained underweighted in health care, consumer staples, and materials.

In today’s environment of low 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.

Stock selection hurt the portfolio during the period. TripAdvisor Holdings was the biggest detractor. The company is transitioning to a business model that allows users to book directly online through its site. Although usage trends for InstantBook are improving, user behavior has been more difficult to change than expected. The company plans to increase its marketing spending in order to accelerate revenue growth and attract customers to the new feature. Such a campaign could push revenues higher, but it could also temporarily affect EBITDA. Despite InstantBook’s slow takeoff, we believe the company has the assets in place to build a successful transaction business that will supplement its core travel search business.

Our largest relative contributor during the period was Celgene Corporation. Revlimid, its drug for multiple myeloma, has grown nearly 30% year-over-year, with notable international success. We believe the company is poised to benefit from additional indications for some of its drugs (particularly Revlimid), increased use of others, and international growth opportunities.

The equity market has delivered positive absolute results over the past several years. However, Jackson Square Partners believes that ever-changing market sentiment has demonstrated that more than just fundamental factors are affecting stock prices. A lack of confidence in the tepid fundamental outlook since the financial crisis suggests that many investors have struggled to accurately predict the pace of global economic recovery. They are also uncertain about assessing external factors that threaten economic fundamentals, such as central bank actions and fiscal policy debates across the globe.

President Trump’s surprising victory in November and the corresponding market reaction reflect growing investor optimism,

at least in the short term, that upcoming policy shifts could stimulate economic growth. We believe it is too early to determine the direction or magnitude of such moves, but we will closely monitor the launch of Trump’s tenure with a keen eye on potentially significant changes.

Equity market strength over the six months was fueled by positive U.S. economic data and the surprise election of Donald Trump. The president’s proposed policies of lower taxes, increased fiscal spending, and looser regulations were generally perceived as pro-growth. This gave a boost to cheaper and more economically sensitive areas of the market. At the same time, U.S. economic data, including retail sales, housing starts, unemployment claims, and wages, strengthened.

The portfolio was hindered during the period by disappointing stock selection and a challenging environment for our investment style. The market’s preference for cheaper stocks hurt because the portfolio’s quality growth companies typically trade at a valuation premium. At the sector level, our largest detractors were information technology—mainly our decision to not own Apple—and consumer discretionary, in part because of a position in O’Reilly Automotive. Other top individual detractors included health care holding Cerner Corporation and consumer staples companies Monster Beverage Corporation, Kroger, and Estee Lauder. Top contributors included UnitedHealth Group (health care), Union Pacific (industrials), Adobe Systems (information technology), Affiliated Managers Group (financials), and Mastercard (information technology).

As always, we believe other investors’ focus on near-term events creates opportunities for investors such as ourselves, who analyze companies over the long term to achieve excess returns. We remain focused on identifying companies with durable growth drivers whose stocks present compelling risk/reward opportunities.

Hurt by the U.S. election’s focus on drug pricing earlier in the period, health care stocks dragged on portfolio returns despite a later rebound as concerns abated somewhat. Bristol-Myers Squibb declined following disappointing clinical data from its immuno-oncology program. Allergan and Shire, which have grown through acquisitions, were affected by

regulatory changes that threatened to remove the tax benefits of mergers between U.S. and offshore companies.

Technology positions were strong contributors but underperformed the benchmark sector. Apple’s strength reflected the proliferation of the iOS platform across mobile phones, tablets, and personal computers and the financial power and attractive margins of the company’s hardware products. Semiconductor-maker NVIDIA benefited from its focus on high-growth markets, where it is offering high-value-added graphics products. Qualcomm fell because of new and ongoing antitrust litigation.

In the wake of the U.S. election, the financial and industrial sectors performed well in anticipation of a less onerous regulatory environment and stimulus to infrastructure investment. We believe Goldman Sachs’s strong capital base and leading positions in investment banking, capital markets, trading, and asset management provide attractive exposure to long-term global economic expansion. Morgan Stanley is a formidable competitor and has a balanced and diversified business model.

Boeing’s gain reflected strong financial results and the 787 Dreamliner commercial jet’s cash generation. In consumer discretionary, Netflix rose on robust subscriber growth. As the company develops into a global network, its earnings potential grows significantly.

We conduct rigorous research to determine company, industry, and sector fundamentals and prospects over intermediate and longer terms, projecting how markets, industries, and businesses will evolve over time. With this perspective, we build the portfolio through individual stock selection based on company fundamentals.

The election victory of Donald Trump dominated the news during the period. As in 2016, markets were primarily driven by politics and sentiment. Given our long-term view and focus on company fundamentals, it was pleasing to see the companies held by the portfolio continue to deliver outstanding operational results. We are heartened by their extensive investment for future growth.

Our philosophy and process focus on finding and holding exceptional growth companies, as defined by their culture, growth opportunity, and competitive edge. As a result of our research, we acquired a diverse range of stocks with attractive and durable growth prospects. CoStar Group (commercial real estate data), Ellie Mae (mortgage origination software), NVIDIA (graphic-chip designer), and Vertex Pharmaceuticals (cystic fibrosis drug developer) were all purchased over the

period. Funds for these stocks came from the complete sales of Apache, Colgate-Palmolive, Genomic Health, Idexx Laboratories, and O’Reilly Automotive.

Despite political uncertainties, we remain very optimistic about the portfolio’s prospects; some of its holdings are literally changing the world through their innovation, expertise, and vision. We look forward to updating you on their progress and finding more exceptional growth companies over the coming year.

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

During the six months ended February 28, 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 aggregate settlement values 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, 2013–2016), and for the period ended February 28, 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 absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. 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 February 28, 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) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The investment advisory firms Wellington Management Company LLP, Jackson Square Partners, LLC, 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 Wellington Management Company LLP, Jackson Square Partners, LLC, 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 six months ended February 28, 2017, the aggregate investment advisory fee represented an effective annual basic rate of 0.18% of the fund’s average net assets, before a decrease of $908,000 (0.03%) based on performance.

U.S. Growth Fund

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 February 28, 2017, the fund had contributed to Vanguard capital in the amount of $485,000, representing 0.01% of the fund’s net assets and 0.19% 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 six months ended February 28, 2017, these arrangements reduced the fund’s expenses by $123,000 (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).

The following table summarizes the market value of the fund’s investments as of February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	6,626,384	21,392	2,630
Preferred Stocks	—	—	107,885
Convertible Preferred Stocks	—	—	13,453
Temporary Cash Investments	201,468	21,186	—
Futures Contracts—Liabilities¹	(806)	—	—
Total	6,827,046	42,578	123,968
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 six months ended February 28, 2017. Transfers into or out of Level 3 are recognized based on values as of the date of transfer.


			Investments in
	Investments in	Investments in	Convertible
	Common Stocks	Preferred Stocks	Preferred Stocks
Amount Valued Based on Level 3 Inputs	($000)	($000)	($000)

Change in Unrealized Appreciation (Depreciation)	—	273	—
Balance as of February 28, 2017	2,630	107,885	13,453

The following table provides quantitative information about the significant unobservable inputs used in fair value measurement as of February 28, 2017:


	Fair Value
Security Type	($000)	Valuation Technique	Unobservable Input	Amount
Common Stocks	2,630	Market Approach	Recent Market Transaction	$50.192
Preferred Stocks	107,885	Market Approach	Recent Market Transaction	50.192
			Recent Market Transaction	48.772
			Comparable Company Approach	18.930
			Comparable Company Approach	6.360
Convertible
Preferred Stocks	13,453	Market Approach	Recent Market Transaction	105.000

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. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	691	81,635	2,796
E-mini S&P Mid-Cap 400 Index	March 2017	262	45,266	962
				3,758

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

G. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes. These differences will

U.S. Growth Fund

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. The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year.

At February 28, 2017, the cost of investment securities for tax purposes was $4,993,307,000. Net unrealized appreciation of investment securities for tax purposes was $2,001,091,000, consisting of unrealized gains of $2,140,369,000 on securities that had risen in value since their purchase and $139,278,000 in unrealized losses on securities that had fallen in value since their purchase.

H. During the six months ended February 28, 2017, the fund purchased $1,089,501,000 of investment securities and sold $1,250,278,000 of investment securities, other than temporary cash investments.

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


	Six Months Ended		Year Ended

J. Management has determined that no material events or transactions occurred subsequent to February 28, 2017, that would require recognition or disclosure in these financial statements.

About Your Fund’s Expenses

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

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

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

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

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

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

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

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


Six Months Ended February 28, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
U.S. Growth Fund	8/31/2016	2/28/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,047.46	$2.08
Admiral Shares	1,000.00	1,048.15	1.42
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.76	$2.06
Admiral Shares	1,000.00	1,023.41	1.40

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 0.41% for Investor Shares and 0.28% 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 (181/365).

Trustees Approve Advisory Arrangements

The board of trustees of Vanguard U.S. Growth Fund has renewed the fund’s investment advisory arrangements with Baillie Gifford Overseas Ltd. (Baillie Gifford), Jackson Square Partners, LLC (Jackson Square), Jennison Associates LLC (Jennison), Wellington Management Company LLP (Wellington Management), and William Blair Investment Management, LLC (William Blair). The board determined that renewing the fund’s advisory arrangements was in the best interests of the fund and its shareholders.

The board based its decision upon an evaluation of each advisor’s investment staff, portfolio management process, and performance. 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 advisors 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 during 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 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 the fund’s investment management services over both the short and long term and took into account the organizational depth and stability of each advisor. The board considered the following:

Baillie Gifford. Baillie Gifford is a unit of Baillie Gifford & Co., which was founded in 1908 and is among the largest independently owned investment management firms in the United Kingdom. Baillie Gifford aims to deliver outstanding investment performance for its clients by identifying exceptional growth companies in the United States and investing in them long enough for the advantages of their business models and strength of their cultures to become the dominant drivers of their stock prices. This long-term horizon allows the advisor to harness the asymmetry inherent in equity markets to capture the disproportionate impact of successful investments in its clients’ portfolios. Baillie Gifford began managing a portion of the fund in 2014.

Jackson Square. Founded in February 2014, Jackson Square invests primarily in common stocks of large-capitalization, growth-oriented companies that it believes have long-term capital appreciation potential and are expected to grow faster than the U.S. economy. Jackson Square uses a bottom-up approach, seeking companies that have large-end market potential, dominant business models, and strong free cash flow generation that is attractively priced compared to the intrinsic value of the securities. Jackson Square was founded by the same investment team that has managed a portion of the fund since 2010, previously as a part of Delaware Investments.

Jennison. Jennison, founded in 1969, is an indirect, wholly owned subsidiary of Prudential Financial Inc. Jennison uses internal fundamental research and a highly interactive stock selection process to identify companies that exhibit above-average growth in units, revenues, earnings, and cash flows. When analyzing a company for purchase or sale, Jennison focuses on the duration of the company’s growth opportunity and seeks to capture inflection points in its growth trajectory. Jennison began managing a portion of the fund in 2014.

Wellington Management. Founded in 1928, Wellington Management is among the nation’s oldest and most respected institutional investment managers. The firm employs a traditional, bottom-up fundamental research approach to identify companies with sustainable growth advantages and reasonable valuations. Wellington Management identifies companies that have demonstrated above-average growth in the past and follows up with a thorough review of each company’s business model and an assessment of its valuation. The goal of this review is to identify companies with high returns on capital, superior business management, and high-quality balance sheets. Wellington Management has managed a portion of the fund since 2010.

William Blair. Founded in 1935, William Blair is an independently owned full-service investment firm. William Blair uses an investment process that relies on thorough fundamental research. Based on this process, it invests in quality growth companies that it believes will grow faster than the market expects or sustain an above-average growth rate for longer than the market expects. In selecting stocks, William Blair considers each company’s leadership position within the company’s market, the quality of products or services it provides, its return on equity, its accounting policies, and the quality of the management team. William Blair has advised a portion of the fund since 2004.

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

Investment performance

The board considered the short- and long-term performance of the fund and each advisor, including any periods of outperformance or underperformance compared with a relevant benchmark and peer group. The board concluded that the performance was such that each 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 below the average expense ratio charged by funds in its peer group and that the fund’s advisory fee rate was also well below its peer-group average. Information about the fund’s expenses appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements section, which also includes information about the fund’s advisory fee rate.

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

The benefit of economies of scale

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

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

Glossary

30-Day SEC Yield. A fund’s 30-day SEC yield is derived using a formula specified by the U.S. Securities and Exchange Commission. Under the formula, data related to the fund’s security holdings in the previous 30 days are used to calculate the fund’s hypothetical net income for that period, which is then annualized and divided by the fund’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s income is based on its current market yield to maturity (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.

The following table provides information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482. 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

• Vanguard International Growth Fund returned almost 4% for the six months ended February 28, 2017, behind its benchmark but ahead of the average return for its peers.

• The fund’s advisors added value in Europe, notably among Italian, Dutch, Swedish, and Danish stocks.

• Results for the fund from Pacific region countries were negative or more or less flat.

Japanese health care stocks and an underweighting of Australian financial institutions were among the biggest detractors.

• Overall returns from emerging markets were slightly negative. The fund’s lack or near-lack of exposure to poorly performing countries like Malaysia, the Philippines, and Mexico was more than offset by disappointing selection in Brazil and South Korea.

• In terms of sectors, the fund’s performance relative to its benchmark was mixed.

The advisors added value in consumer discretionary and telecommunication services, but their selections proved subpar in financials, industrials, information technology, and materials.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

The overall goal of this longtime client: Give employees a better chance to achieve financial security in retirement.

Changing the retirement landscape

Am I singling out an isolated Vanguard success story? Absolutely not.

The growing use of target-date funds is another enormous benefit. More than 70% of all participants in Vanguard plans invest at least part of their retirement savings in

these age-appropriate, diversified strategies. And nearly 50% of Vanguard participants are invested solely in a single target-date fund.

Consider a do-it-yourself autopilot

But what if you don’t have access to a world-class, employer-based retirement plan? Unfortunately, not everyone does, which is an important policy issue.

Winning by default

As always, thank you for investing with Vanguard.

Sincerely,

Advisors’ Report

For the six months ended February 28, 2017, Vanguard International Growth Fund returned 3.85% for Investor Shares (3.91% for Admiral Shares), behind its benchmark index but ahead of the average return of peer funds. 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 half year and of how the portfolio’s positioning reflects this assessment. These comments were prepared on March 16, 2017.

political events in the last six months, and more are surely on the horizon, we think that the deeper trends are more important. Accordingly, we have not changed our portfolio, or our approach, in response to recent events.

Politics matters, of course. But over the long term, a company’s success or failure is far more likely to be driven by management strategy and execution than by any other factor. Our job as investors is to cut through the short-term noise and focus on identifying long-term trends and tomorrow’s winning companies.

Long-term trends can only be exploited by leaders who run their businesses with long-term time horizons. Therefore, we seek companies with outstanding management teams and strong, deeply entrenched cultures. At a time of chronic underinvestment, we admire companies that are prepared to be bold, because we know that really important breakthroughs are hard to achieve. They require heavy investment, risk-taking, and an atmosphere in which creativity is allowed to flourish.

Founder-led or family-owned companies remain a fertile hunting ground for these rare corporate traits, and many of our holdings exhibiting them did well. Amazon, SoftBank, and Tesla are all led by founders who have visions for their businesses that extend decades into the future. These companies also share a commitment to investing the resources to realize those visions. In Europe, there may be fewer iconic entrepreneurs, but the supportive influence of significant shareholders with investment horizons stretching across generations can be incredibly important. Family control at luxury goods companies Kering and Richemont has helped build and protect valuable brands, while the Agnelli family’s stake in Fiat and Ferrari has been vital in supporting CEO Sergio Marchionne’s ambitious plans for growth.

Some companies decide to take a different path. During the half year, several holdings in our portfolio agreed to be acquired (in two cases, by other portfolio holdings). Swiss agribusiness Syngenta was bought by ChemChina; U.K. chip designer ARM was taken over by Japanese telecommunications and internet giant SoftBank; and U.K. travel website Skyscanner was purchased by Ctrip, China’s largest travel company.

While all deals were at a premium and we are pleased to retain indirect exposure to ARM and Skyscanner through their new owners, there is a sense of disappointment that these exciting businesses could not remain independent. Nervousness about both the scale of future investment and the patience of markets was a common feature in these deals—a detail that reminds us of how important it is to support great companies.

There were no particular themes among the weaker performers. Spain’s Banco Popular has continued to struggle following its rights issue last year, while ANI Technologies, the Indian online taxi-hailing business known as Ola Cabs, fell

in value after raising additional capital from SoftBank. While Ola has a market-leading position in India, it faces competition from Uber; for long-term growth, the company needs the resources of an investor like SoftBank.

We have not made any new purchases, preferring to add to existing holdings such as Dutch semiconductor manufacturer ASML and Danish biotechnology company Genmab. In both cases, this addition reflects our increasing confidence in the opportunity available to these businesses. We have also added to AIA, the Asian life insurance company, using funds from our sale of Prudential.

North America Inc.

Portfolio Manager:

Simon Webber, CFA

International equities made modest progress over the half year, navigating a changing macroeconomic and political framework. After the U.S. presidential election, market focus was firmly on the question of whether Donald Trump would follow through on his promised tax cuts and trade-policy reforms. Earlier, a period of rising global growth expectations began over the summer, supported by rising commodity prices and an inventory-stocking cycle that gave a boost to cyclical stocks. A fourth-quarter tilt toward value stocks was the most pronounced shift in style over a single quarter in more than a decade. With global yields expected to rise, and the operating environment for banks expected to improve, the financial sector was particularly strong. Conversely, quality growth stocks and defensive sectors were among the market’s weaker performers.

Against a backdrop of aggressive rotation into cyclical stocks and lower quality leverage, the portfolio underperformed the index, largely because of style factors. However, performance was also adversely affected by concerns regarding two stocks, Capita and GEA Group. In the case of business process outsourcing company Capita, the firm disclosed a number of charges for underperforming contracts, blemishing a historically exemplary record of delivering good service levels and savings for clients. This has raised execution concerns under current management. We sold our position given the deteriorating outlook and higher risk profile.

GEA, which supplies manufacturing equipment to the food and dairy industries, also fell following warnings of a weaker outlook. Its announcement was even more of a surprise than Capita’s was, as it came just two weeks after a capital markets day at which the company had outlined plans for significant cost reductions and efficiency improvements. While management credibility has clearly been damaged, we believe much of the shortfall is caused by cyclical issues, and we still see attractive long-term growth drivers and plenty of scope for management to improve execution. We continue to monitor the position and its alignment with our investment thesis.

One of the strongest holdings was diversified miner BHP Billiton, which benefited from an ongoing rally in the price of its key commodities—iron ore, copper, and coking coal. Because BHP’s key assets are among the lowest cost in their respective markets, the company has weathered the recent downturn better than most of its competitors.

An enduring theme in the portfolio is the excellent structural growth prospects for technology companies, from software enablers like SAP to internet platforms such as Tencent and Alibaba. We opened a position in Recruit, which owns Indeed—the world’s biggest and most successful online job-finding site. We believe the market underappreciates this asset, and we expect Recruit’s domestic Japanese business to benefit from a shrinking labor force. We also purchased Deutsche Telekom, as the outlook for its domestic market looks more promising in light of recent announcements that competitors were cutting back promotions. The company is still gaining market share in the United States via its strategic majority stake in T-Mobile US, which continues to grow through its disruptive strategy and remains a takeover target.

Going forward, we believe that plenty of opportunity remains in international equity markets. Continental European economies are in the midst of their most robust and sustainable economic growth since before the global financial crisis, yet the market focus remains on political risks. This sets up the potential of a strong equity market if those risks fail to manifest. An upturn in global trade is also set to help many Asian businesses in 2017. We look ahead with confidence and believe that a disciplined strategy of identifying companies that have strong competitive advantages—and sustainably manage their business for the long term—will continue to pay off.

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 clearing-

International Growth Fund

house, 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.

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 counter-parties, 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 aggregate settlement values and 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 six months ended February 28, 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 aggregate settlement values at each quarter-end during the period. The fund’s average investment in forward currency contracts represented 2% of net assets, based on the average of 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, 2013–2016), and for the period ended February 28, 2017, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

International Growth Fund

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 value of securities loaned. Daily market fluctuations could cause the value of loaned securities to be more or less than the value of the collateral received. When this occurs, the collateral is adjusted and settled on the next business day. The fund further mitigates its counterparty risk by entering into securities lending transactions only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master securities lending agreements with its counterparties. The master securities lending agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. 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 February 28, 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.

International Growth Fund

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.

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 six months ended February 28, 2017, the aggregate investment advisory fee represented an effective annual basic rate of 0.15% of the fund’s average net assets, before an increase of $2,394,000 (0.02%) 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 February 28, 2017, the fund had contributed to Vanguard capital in the amount of $1,657,000, representing 0.01% of the fund’s net assets and 0.66% 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.

At February 28, 2017, the counterparty had deposited in segregated accounts cash with a value of $710,000 in connection with open forward currency contracts.

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.

International Growth Fund

During the six months ended February 28, 2017, the fund realized net foreign currency losses of $20,480,000, which decreased distributable net income for tax purposes; accordingly, such losses have been reclassified from accumulated net realized losses to overdistributed net investment income.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $491,209,000 to offset future net capital gains. Of this amount, $212,308,000 is subject to expiration on August 31, 2018. Capital losses of $278,901,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $19,175,100,000.

Net unrealized appreciation of investment securities for tax purposes was $4,625,124,000, consisting of unrealized gains of $5,931,547,000 on securities that had risen in value since their purchase and $1,306,423,000 in unrealized losses on securities that had fallen in value since their purchase.

G. During the six months ended February 28, 2017, the fund purchased $2,150,558,000 of investment securities and sold $2,112,567,000 of investment securities, other than temporary cash investments.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
International Growth Fund	8/31/2016	2/28/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,038.55	$2.27
Admiral Shares	1,000.00	1,039.11	1.62
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.56	$2.26
Admiral Shares	1,000.00	1,023.21	1.61

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 0.45% 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 (181/365).

Trustees Approve Advisory Arrangements

The board of trustees of Vanguard International Growth Fund has renewed the fund’s investment advisory arrangements with Baillie Gifford Overseas Ltd. (Baillie Gifford) and Schroder Investment Management North America Inc. (Schroder Inc.), as well as the sub-advisory agreement with Schroder Investment Management North America Ltd. (Schroder Ltd.). The board determined that renewing the fund’s advisory arrangements was in the best interests of the fund and its shareholders. Please note that in July, the fund’s trustees modified its investment advisory arrangement. M&G Investment Management Limited no longer serves as one of the fund’s advisors.

The board based its decision upon an evaluation of each 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 advisory oversight and product management. The Portfolio Review Department met regularly with the advisors and made monthly presentations to the board during the fiscal year that directed the board’s focus to relevant information and topics.

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 each advisor. The board considered the following:

Baillie Gifford. Baillie Gifford is a unit of Baillie Gifford & Co., which was founded in 1908 and is among the largest independently owned investment management firms in the United Kingdom. Baillie Gifford uses fundamental research to make long-term investments in companies that have above-average growth potential resulting from sustainable competitive advantages, special cultures and management, or competitive strength in underestimated technology shifts. Baillie Gifford believes that equities’ asymmetrical return pattern means that alpha is generated by focusing on the upside and the potential to earn exponential returns rather than being overly concerned with avoiding losing investments. The advisor takes a bottom-up, stock-driven approach to sector and country allocation. Baillie Gifford has advised a portion of the fund since 2003.

Schroder. Schroders plc, the parent company of Schroder Inc. and Schroder Ltd. (collectively, Schroder), founded in 1804, specializes in global equity and fixed income management. Schroder seeks to invest in securities of international companies where it has identified a significant growth gap, which is defined as forward earnings growth that is not yet recognized by the market. Schroder believes that market inefficiencies often drive material differences between underlying company

fundamentals and market estimates. The advisor also believes that in-depth fundamental research, incorporating a comprehensive macroeconomic viewpoint and a robust framework of fundamental risk analysis, is the most reliable means of finding those companies and identifying the growth gap. Schroder Inc. has advised the fund since its inception in 1981, and its affiliate Schroder Ltd. has advised the fund since 2003.

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

Investment performance

Cost

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

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

The benefit of economies of scale

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

We conduct our business with integrity as a faithful steward of your assets. This message is shown translated into seven languages, reflecting our expanding global presence.

Your Fund’s Performance at a Glance

• Vanguard FTSE Social Index Fund returned more than 10% for the six months ended February 28, 2017, closely tracking its target benchmark, the FTSE4Good US Select Index, and outpacing 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 human rights criteria, such as the financial, technology, and health care sectors. It has less exposure to sectors where companies may fall short of the index’s requirements, such as oil and gas and industrials.

• All ten sectors advanced. Financials, the largest sector in the fund, returned 19% and had the biggest impact on overall returns. Banks and financial service firms did particularly well.

• Technology and industrials (both +14%) were the other top contributors. Basic materials (+7%), consumer services (+6%), health care (+5%), and consumer goods (+2%) contributed modestly.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

The overall goal of this longtime client: Give employees a better chance to achieve financial security in retirement.

Changing the retirement landscape

Am I singling out an isolated Vanguard success story? Absolutely not.

The growing use of target-date funds is another enormous benefit. More than 70% of all participants in Vanguard plans invest at least part of their retirement savings in

these age-appropriate, diversified strategies. And nearly 50% of Vanguard participants are invested solely in a single target-date fund.

Consider a do-it-yourself autopilot

But what if you don’t have access to a world-class, employer-based retirement plan? Unfortunately, not everyone does, which is an important policy issue.

Winning by default

As always, thank you for investing with Vanguard.

Sincerely,

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.

During the six months ended February 28, 2017, the fund’s average investments in long and short futures contracts represented 0% and 0% of net assets, respectively, based on the average of aggregate settlement values at each quarter-end during the period. The fund had no open futures contracts at February 28, 2017.

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, 2013–2016), and for the period ended February 28, 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 absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. 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 February 28, 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 February 28, 2017, the fund had contributed to Vanguard capital in the amount of $187,000, representing 0.01% of the fund’s net assets and 0.07% 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 a re 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 February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	2,824,507	—	—
Temporary Cash Investments	3,999	300	—
Total	2,828,506	300	—

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.

FTSE Social Index Fund

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $22,292,000 to offset future net capital gains. Of this amount, $394,000 is subject to expiration on August 31, 2019. Capital losses of $21,898,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $2,137,683,000. Net unrealized appreciation of investment securities for tax purposes was $691,123,000, consisting of unrealized gains of $724,490,000 on securities that had risen in value since their purchase and $33,367,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2017, the fund purchased $481,599,000 of investment securities and sold $202,917,000 of investment securities, other than temporary cash investments.

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

About Your Fund’s Expenses

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


Six Months Ended February 28, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
FTSE Social Index Fund	8/31/2016	2/28/2017	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,105.67	$1.20
Institutional Shares	1,000.00	1,106.95	0.63
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.65	$1.15
Institutional Shares	1,000.00	1,024.20	0.60

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that
period are 0.23% for Investor Shares and 0.12% 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 (181/365).

Glossary

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

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

Foreign Holdings. The percentage of a fund represented by securities 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.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

The overall goal of this longtime client: Give employees a better chance to achieve financial security in retirement.

Changing the retirement landscape Am I singling out an isolated Vanguard success story? Absolutely not.

Insights from the relatively new discipline of behavioral finance have contributed to the advances. Simply put, retirement plans are making natural human inertia work for future retirees, rather than against them, by putting savings on autopilot as much as possible.

Citigroup Three-Month U.S. Treasury Bill Index	0.19	0.32	0.10

CPI
Consumer Price Index	1.14%	2.74%	1.36%

The growing use of target-date funds is another enormous benefit. More than 70% of all participants in Vanguard plans invest at least part of their retirement savings in these age-appropriate, diversified strategies. And nearly 50% of Vanguard participants are invested solely in a single target-date fund.

Consider a do-it-yourself autopilot But what if you don’t have access to a world-class, employer-based retirement plan? Unfortunately, not everyone does, which is an important policy issue.

Winning by default

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Consumer Discretionary Index Fund

Notes to Financial Statements

Vanguard Consumer Discretionary Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: 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 six months ended February 28, 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 aggregate settlement values at each quarter-end during the period. The fund had no open futures contracts at February 28, 2017.

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 feeschargedto borrowers plusincome earned oninvested 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 February 28, 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.

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 forthese costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $165,000, representing 0.01% of the fund’s net assets and 0.07% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

C. Variousinputs may be used to determine the value of the fund’sinvestments. Theseinputs 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’sinvestments as of February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	2,310,690	—	21
Temporary Cash Investments	30,485	—	—
Total	2,341,175	—	21

Consumer Discretionary Index Fund

During the six months ended February 28, 2017, the fund realized $33,523,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $34,552,000 to offset future net capital gains. Of this amount, $9,625,000 is subject to expiration dates; $858,000 may be used to offset future net capital gains through August 31, 2017, $7,274,000 through August 31, 2018, and $1,493,000 through August 31, 2019. Capital losses of $24,927,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $2,136,938,000. Net unrealized appreciation of investment securities for tax purposes was $204,258,000, consisting of unrealized gains of $366,866,000 on securities that had risen in value since their purchase and $162,608,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2017, the fund purchased $268,825,000 of investment securities and sold $207,569,000 of investment securities, other than temporary cash investments. Purchases and sales include $163,519,000 and $124,454,000, 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 six months ended February 28, 2017, such purchases and sales were $1,205,000 and $22,182,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

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.

During the six months ended February 28, 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 aggregate settlement values at each quarter-end during the period. The fund had no open futures contracts at February 28, 2017.

Consumer Staples IndexFund

the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents feeschargedto borrowers plusincome earned oninvested 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 February 28, 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.

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 forthese costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $290,000, 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.

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

At February 28, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

Consumer Staples IndexFund

During the six months ended February 28, 2017, the fund realized $89,035,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $24,410,000 to offset future net capital gains. Of this amount, $5,537,000 is subject to expiration on August 31, 2018. Capital losses of $18,873,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $3,685,429,000. Net unrealized appreciation of investment securities for tax purposes was $619,255,000, consisting of unrealized gains of $643,977,000 on securities that had risen in value since their purchase and $24,722,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2017, the fund purchased $290,705,000 of investment securities and sold $297,321,000 of investment securities, other than temporary cash investments. Purchases and sales include $199,183,000 and $236,019,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

Energy Index Fund

Notes to Financial Statements

Vanguard Energy Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: 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.

Energy Index Fund

represents feeschargedto borrowers plusincome earned oninvested 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 February 28, 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.

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,anddistributionservices atVanguard’scostofoperations (as defined bythe 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 ofoperations(such asdeferred compensation/benefitsand risk/insurance costs);thefund’sliability for these costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $379,000, representing 0.01% of the fund’s net assets and 0.15% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

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

At February 28, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	150	17,721	7

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

Energy Index Fund

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

During the six months ended February 28, 2017, the fund realized $42,497,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $408,172,000 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 $339,888,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $5,666,024,000. Net unrealized depreciation of investment securities for tax purposes was $521,063,000, consisting of unrealized gains of $236,868,000 on securities that had risen in value since their purchase and $757,931,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2017, the fund purchased $625,944,000 of investment securities and sold $514,642,000 of investment securities, other than temporary cash investments. Purchases and sales include $265,018,000 and $208,297,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

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.

During the six months ended February 28, 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 aggregate settlement values at each quarter-end during the period. The fund had no open futures contracts at February 28, 2017.

Financials Index Fund

The fund had no borrowings outstanding at February 28, 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. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

B. 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,anddistributionservices atVanguard’scostofoperations (as defined bythe 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 ofoperations(such asdeferred compensation/benefitsand risk/insurance costs);thefund’sliability for these costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $408,000, representing 0.01% of the fund’s net assets and 0.16% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

C. Variousinputs may be used to determine the value of the fund’sinvestments. Theseinputs 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’sinvestments as of February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	6,266,008	—	188
Temporary Cash Investments	3,562	—	—
Total	6,269,570	—	188

Financials Index Fund

During the six months ended February 28, 2017, the fund realized $90,002,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $157,415,000 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 $13,086,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $5,385,687,000. Net unrealized appreciation of investment securities for tax purposes was $884,071,000, consisting of unrealized gains of $920,316,000 on securities that had risen in value since their purchase and $36,245,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2017, the fund purchased $1,965,390,000 of investment securities and sold $614,359,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,630,130,000 and $535,090,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

Health Care Index Fund

Notes to Financial Statements

Vanguard Health Care Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: 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.

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, 2013–2016), and for the period ended February 28, 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. 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 absence of a default the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Net Assets for the return of the collateral, during the period the securities are on loan. Securities lending income represents feeschargedto borrowers plusincome earned oninvested 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.

5. 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 February 28, 2017, or at any time during the period then ended.

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

Health Care 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,anddistributionservices atVanguard’scostofoperations (as defined bythe 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 ofoperations(such asdeferred compensation/benefitsand risk/insurance costs);thefund’sliability for these costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $455,000, representing 0.01% of the fund’s net assets and 0.18% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

C. Variousinputs may be used to determine the value of the fund’sinvestments. Theseinputs 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’sinvestments as of February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	6,788,035	—	333
Temporary Cash Investments	24,225	—	—
Total	6,812,260	—	333

During the six months ended February 28, 2017, the fund realized $133,421,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $89,253,000 that may be carried forward indefinitely to offset future net capital gains. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $6,074,376,000. Net unrealized appreciation of investment securities for tax purposes was $738,217,000, consisting of unrealized gains of $1,050,837,000 on securities that had risen in value since their purchase and $312,620,000 in unrealized losses on securities that had fallen in value since their purchase.

Health Care Index Fund

E. During the six months ended February 28, 2017, the fund purchased $567,911,000 of investment securities and sold $546,063,000 of investment securities, other than temporary cash investments. Purchases and sales include $406,581,000 and $373,687,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

Industrials Index Fund

Notes to Financial Statements

Vanguard Industrials Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: 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.

Industrials Index Fund

The fund had no borrowings outstanding at February 28, 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.

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 ofoperations(suchasdeferredcompensation/benefitsandrisk/insurancecosts);thefund’sliability for these costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $209,000, 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. Variousinputs may be used to determine the value of the fund’sinvestments. Theseinputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

At February 28, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	16	1,890	(4)

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

Industrials Index Fund

During the six months ended February 28, 2017, the fund realized $93,187,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $16,635,000 to offset future net capital gains of $11,504,000 through August 31, 2018, and $5,131,000 through August 31, 2019. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $2,649,509,000. Net unrealized appreciation of investment securities for tax purposes was $396,900,000, consisting of unrealized gains of $456,070,000 on securities that had risen in value since their purchase and $59,170,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2017, the fund purchased $772,480,000 of investment securities and sold $435,353,000 of investment securities, other than temporary cash investments. Purchases and sales include $593,045,000 and $351,166,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

At February 28, 2017, one shareholder was the record or beneficial owner of 46% 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.

H. Management has determined that no material events or transactions occurred subsequent to February 28, 2017, that would require recognition or disclosure in these financial statements.

The following table summarizes the market value of the fund’sinvestments as of February 28, 2017, based on the inputs used to value them:


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

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	90	10,633	(29)

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

During the six months ended February 28, 2017, the fund realized $302,803,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $82,732,000 to offset future net capital gains. Of this amount, $47,958,000 is subject to expiration dates; $7,582,000 through August 31, 2017, $20,048,000 through August 31, 2018, and $20,328,000 through August 31, 2019. Capital losses of $34,774,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $9,031,254,000. Net unrealized appreciation of investment securities for tax purposes was $3,301,092,000, consisting of unrealized gains of $3,433,792,000 on securities that had risen in value since their purchase and $132,700,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2017, the fund purchased $1,970,182,000 of investment securities and sold $895,116,000 of investment securities, other than temporary cash investments. Purchases and sales include $1,455,059,000 and $588,213,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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.

Materials Index Fund

The fund had no borrowings outstanding at February 28, 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.

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,anddistributionservices atVanguard’scostofoperations (as defined bythe 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 ofoperations(such asdeferred compensation/benefitsand risk/insurance costs);thefund’sliability for these costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $162,000, 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.

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

At February 28, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	22	2,599	(1)

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

Materials Index Fund

During the six months ended February 28, 2017, the fund realized $48,482,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $63,262,000 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. Capital losses of $23,972,000 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.The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $2,180,293,000. Net unrealized appreciation of investment securities for tax purposes was $130,460,000, consisting of unrealized gains of $269,021,000 on securities that had risen in value since their purchase and $138,561,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2017, the fund purchased $630,458,000 of investment securities and sold $185,387,000 of investment securities, other than temporary cash investments. Purchases and sales include $530,653,000 and $141,925,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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

Telecommunication Services IndexFund

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 aggregate settlement values 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).

Telecommunication Services IndexFund

the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the absence of a default the fund may experience delays and costs in recovering the securitiesloaned. The fundinvests 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 onloan. Securitieslending 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 February 28, 2017, or at any time during the period then ended.

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,anddistributionservices atVanguard’scostofoperations (as defined bythe 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 ofoperations(such asdeferred compensation/benefitsand risk/insurance costs);thefund’sliability for these costs of operations isincluded in Payables to Vanguard on the Statement of Assets and Liabilities.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $113,000 representing 0.01% of the fund’s net assets and 0.05% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	31	3,662	2

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

During the six months ended February 28, 2017, the fund realized $54,098,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $77,701,000 to offset future net capital gains. Of this amount, $45,285,000 is subject to expiration dates; $7,492,000 may be used to offset future net capital gains through August 31, 2017, $26,335,000 through August 31, 2018, and $11,458,000 through August 31, 2019. Capital losses of $32,416,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $1,563,736,000. Net unrealized depreciation of investment securities for tax purposes was $3,116,000, consisting of unrealized gains of $101,844,000 on securities that had risen in value since their purchase and $104,960,000 in unrealized losses on securities that had fallen in value since their purchase.

The fund had no borrowings outstanding at February 28, 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.

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,anddistributionservices atVanguard’scostofoperations (as defined bythe 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 ofoperations(such asdeferred compensation/benefitsand risk/insurance costs);thefund’sliability for these costs of operations isincluded 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 February 28, 2017,the fund had contributedto Vanguard capitalinthe amountof $212,000, 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. Variousinputs may be used to determine the value of the fund’sinvestments. Theseinputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

At February 28, 2017, 100% of the market value of the fund’s investments was determined based on Level 1 inputs.

Utilities Index Fund

During the six months ended February 28, 2017, the fund realized $67,554,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $20,636,000 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 $14,618,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $2,845,086,000. Net unrealized appreciation of investment securities for tax purposes was $218,324,000, consisting of unrealized gains of $312,739,000 on securities that had risen in value since their purchase and $94,415,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2017, the fund purchased $387,514,000 of investment securities and sold $443,308,000 of investment securities, other than temporary cash investments. Purchases and sales include $262,690,000 and $325,774,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

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.

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 holdingsinshort-termreservesareexcluded.

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.

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 (netincome 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.

Vanguard Extended Duration Treasury

Index Fund

A new format, unwavering commitment

As you begin reading this report, you’ll notice that we’ve made some improvements to the opening sections—based on feedback from you, our clients.

Page 1 starts with a new ”Your Fund’s Performance at a Glance,” a concise, handy summary of how your fund performed during the period.

In the renamed ”Chairman’s Perspective,” Bill McNabb will focus on enduring principles and investment insights.

We’ve modified some tables, and eliminated some redundancy, but we haven’t removed any information.

At Vanguard, we’re always looking for better ways to communicate and to help you make sound investment decisions. Thank you for entrusting your assets to us.

Your Fund’s Performance at a Glance

• ETF Shares of Vanguard Extended Duration Treasury Index Fund returned –16.43% for the six months ended February 28, 2017, slightly better than the fund’s benchmark (–16.62%).

• 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. Treasury prices declined across the maturity spectrum, but longer-term Treasuries (a focus of the fund) fell the most.

• U.S. bond prices declined as the markets grew more upbeat during the period about the prospect of faster growth and higher inflation. That sentiment accelerated following the November election of a new administration that promised more spending on infrastructure, greater deregulation, and possible changes in the federal tax code.

• The sell-off of longer-term Treasuries pushed down their prices and boosted their yields. The 30-day SEC yield of the fund’s ETF Shares began the period at 2.28% and ended it at 3.05%.

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.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

The overall goal of this longtime client: Give employees a better chance to achieve financial security in retirement.

Changing the retirement landscape

Am I singling out an isolated Vanguard success story? Absolutely not.

The growing use of target-date funds is another enormous benefit. More than 70% of all participants in Vanguard plans invest at least part of their retirement savings in

these age-appropriate, diversified strategies. And nearly 50% of Vanguard participants are invested solely in a single target-date fund.

Consider a do-it-yourself autopilot

But what if you don’t have access to a world-class, employer-based retirement plan? Unfortunately, not everyone does, which is an important policy issue.

Winning by default

As always, thank you for investing with Vanguard.

Sincerely,

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 Nasdaq; 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.

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 February 28, 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 purchases of Institutional Shares and Institutional Plus Shares 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 February 28, 2017, the fund had contributed to Vanguard capital in the amount of $94,000, 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. 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 February 28, 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	—	1,343,527	—
Temporary Cash Investments	114	—	—
Total	114	1,343,527	—

Extended Duration Treasury Index Fund

During the six months ended February 28, 2017, the fund realized $22,386,000 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.

At February 28, 2017, the cost of investment securities for tax purposes was $1,319,294,000. Net unrealized appreciation of investment securities for tax purposes was $24,347,000, consisting of unrealized gains of $58,255,000 on securities that had risen in value since their purchase and $33,908,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended February 28, 2017, the fund purchased $322,030,000 of investment securities and sold $274,848,000 of investment securities, other than temporary cash investments. Purchases and sales include $11,217,000 and $139,305,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Extended Duration Treasury Index Fund	8/31/2016	2/28/2017	Period
Based on Actual Fund Return
ETF Shares	$1,000.00	$835.67	$0.32
Institutional Shares	1,000.00	835.60	0.27
Institutional Plus Shares	1,000.00	835.83	0.18
Based on Hypothetical 5% Yearly Return
ETF Shares	$1,000.00	$1,024.45	$0.35
Institutional Shares	1,000.00	1,024.50	0.30
Institutional Plus Shares	1,000.00	1,024.60	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 (181/365).

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.

Chairman’s Perspective

Bill McNabb
Chairman and Chief Executive Officer

Dear Shareholder,

The overall goal of this longtime client: Give employees a better chance to achieve financial security in retirement.

Changing the retirement landscape

Am I singling out an isolated Vanguard success story? Absolutely not.

The growing use of target-date funds is another enormous benefit. More than 70% of all participants in Vanguard plans invest at least part of their retirement savings in

these age-appropriate, diversified strategies. And nearly 50% of Vanguard participants are invested solely in a single target-date fund.

Consider a do-it-yourself autopilot

But what if you don’t have access to a world-class, employer-based retirement plan? Unfortunately, not everyone does, which is an important policy issue.

Winning by default

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

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.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At February 28, 2017, the fund had contributed to Vanguard capital in the amount of $87,000, representing 0.01% of the fund’s net assets and 0.03% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and 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 February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	1,266,915	—	—
Temporary Cash Investments	2,936	200	—
Futures Contracts—Liabilities¹	(8)	—	—
Total	1,269,843	200	—

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	28	3,308	137

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

During the six months ended February 28, 2017, the fund realized $17,716,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $40,810,000 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 $22,031,000 realized beginning in 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $859,052,000.

Net unrealized appreciation of investment securities for tax purposes was $410,999,000, consisting of unrealized gains of $424,825,000 on securities that had risen in value since their purchase and $13,826,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2017, the fund purchased $63,564,000 of investment securities and sold $77,962,000 of investment securities, other than temporary cash investments. Purchases and sales include $23,203,000 and $37,268,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Mega Cap Growth Index Fund

Notes to Financial Statements

Vanguard Mega Cap Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: 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 Growth Index Fund

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

The fund had no borrowings outstanding at February 28, 2017, or at any time during the period then ended.

Mega Cap Growth Index Fund

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At February 28, 2017, the fund had contributed to Vanguard capital in the amount of $175,000, representing 0.01% of the fund’s net assets and 0.07% 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 February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	2,600,185	—	—
Temporary Cash Investments	13,019	200	—
Futures Contracts—Liabilities¹	(14)	—	—
Total	2,613,190	200	—
1 Represents variation margin on the last day of the reporting period.

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	52	6,143	223

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

During the six months ended February 28, 2017, the fund realized $23,562,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $45,935,000 to offset future net capital gains. Of this amount,$4,562,000 is subject to expiration on August 31, 2019. Capital losses of $41,373,000 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. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $1,929,393,000.

Net unrealized appreciation of investment securities for tax purposes was $684,011,000, consisting of unrealized gains of $716,141,000 on securities that had risen in value since their purchase and $32,130,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2017, the fund purchased $277,238,000 of investment securities and sold $145,144,000 of investment securities, other than temporary cash investments. Purchases and sales include $166,693,000 and $51,622,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

Mega Cap Growth Index Fund

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 six months ended February 28, 2017, such purchases and sales were $9,163,000 and $31,571,000, respectively; these amounts are included in the purchases and sales of investment securities noted above.

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


	Six Months Ended		Year Ended
	February 28, 2017		August 31, 2016
	Amount	Shares	Amount	Shares
	($000)	(000)	($000)	(000)

Mega Cap Value Index Fund

Notes to Financial Statements

Vanguard Mega Cap Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: 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 Value Index Fund

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

The fund had no borrowings outstanding at February 28, 2017, or at any time during the period then ended.

Mega Cap Value Index Fund

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At February 28, 2017, the fund had contributed to Vanguard capital in the amount of $121,000, representing 0.01% of the fund’s net assets and 0.05% 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 February 28, 2017, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	1,743,249	—	—
Temporary Cash Investments	—	100	—
Futures Contracts—Liabilities¹	(13)	—	—
Total	1,743,236	100	—
1 Represents variation margin on the last day of the reporting period.

D. At February 28, 2017, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


			($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	March 2017	48	5,671	62

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

During the six months ended February 28, 2017, the fund realized $16,780,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at August 31, 2016, the fund had available capital losses totaling $21,404,000 to offset future net capital gains. Of this amount, $4,326,000 is subject to expiration on August 31, 2019. Capital losses of $17,078,000 realized beginning in 2012 may be carried forward indefinitely under the Regulated Investment Company Modernization Act of 2010, but must be used before any expiring loss carryforwards. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending August 31, 2017; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At February 28, 2017, the cost of investment securities for tax purposes was $1,359,518,000.

Net unrealized appreciation of investment securities for tax purposes was $383,831,000, consisting of unrealized gains of $400,539,000 on securities that had risen in value since their purchase and $16,708,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended February 28, 2017, the fund purchased $224,726,000 of investment securities and sold $160,060,000 of investment securities, other than temporary cash investments. Purchases and sales include $174,614,000 and $45,687,000, respectively, in connection with in-kind purchases and redemptions of the fund’s capital shares.

About Your Fund’s Expenses

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


Six Months Ended February 28, 2017
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	8/31/2016	2/28/2017	Period
Based on Actual Fund Return
Mega Cap Index Fund
ETF Shares	$1,000.00	$1,103.17	$0.37
Institutional Shares	1,000.00	1,103.29	0.31
Mega Cap Growth Index Fund
ETF Shares	$1,000.00	$1,093.67	$0.36
Institutional Shares	1,000.00	1,093.85	0.31
Mega Cap Value Index Fund
ETF Shares	$1,000.00	$1,111.83	$0.37
Institutional Shares	1,000.00	1,111.95	0.31
Based on Hypothetical 5% Yearly Return
Mega Cap Index Fund
ETF Shares	$1,000.00	$1,024.45	$0.35
Institutional Shares	1,000.00	1,024.50	0.30
Mega Cap Growth Index Fund
ETF Shares	$1,000.00	$1,024.45	$0.35
Institutional Shares	1,000.00	1,024.50	0.30
Mega Cap Value Index Fund
ETF Shares	$1,000.00	$1,024.45	$0.35
Institutional Shares	1,000.00	1,024.50	0.30

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for 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 (181/365).
