Chairman’s Letter

Dear Shareholder,

For the 12 months ended November 30, 2015, Vanguard Convertible Securities Fund returned 0.55%. The fund’s result trailed the 1.27% return of its benchmark, the Convertibles Composite Index, but surpassed the –2.23% average return of its peers.

Convertible securities are corporate bonds and preferred stocks that may be exchanged for common stocks at a predetermined price. Convertibles combine the features of bonds and stocks; they offer steady income along with the potential to benefit if the value of their underlying stocks increases.

The fund leans away from riskier convertible securities that lack downside protection. Therefore, as in some prior fiscal years, the fund did not benefit from the market’s recent preference for higher-risk convertibles, which helped the benchmark’s return.

The broad U.S. stock market produced modest returns

U.S. stocks traveled a rocky route on their way to returns that approached 3% for the period. Most of the turmoil came in late summer; markets tumbled in August and September amid fears about the ripple effects of China’s slowing economic growth.

Stocks recovered markedly in October and held firm in November. Central banks in Europe and Asia discussed or enacted more stimulus measures to combat weak growth and low inflation.

2

International stocks returned about –6% as the dollar’s strength hurt results. Returns for emerging markets, which were especially affected by the concerns about China, trailed those of the developed markets of the Pacific region and Europe.

Bonds managed slight gains as investors waited for the Fed

Bond returns were muted over the fiscal year as markets digested the Federal Reserve’s latest statements about the timing of a potential rise in short-term interest rates. (In mid-December, after the close of the reporting period, the Fed raised its target for short-term rates to 0.25%–0.5%.) Investors seemed to alternately seek and shun safe-haven assets, depending on stock market volatility at the time.

The broad U.S. taxable bond market returned 0.97%, with income providing the gain. The yield of the 10-year Treasury note ended November at 2.22%, down from 2.25% a year earlier.

International bond markets (as measured by the Barclays Global Aggregate Index ex USD) returned –8.29%, hindered by the dollar’s strength against many foreign currencies. Without this currency effect, results were positive.

The Fed’s 0%–0.25% target for short-term rates continued to limit returns for money market funds and savings accounts.

Convertibles’ returns reflected small gains for stocks and bonds

The Convertible Securities Fund allows investors to benefit from some of the characteristics of both stocks and bonds. As U.S. stocks and bonds posted small gains for the fiscal year, the convertible market did the same.

Convertible securities tend to be issued by small or midsized firms that often have difficulty securing other sources of financing. They are an attractive funding method because they typically require lower interest payments than bonds. The issuance of convertibles during the period started at a healthy pace but slowed as stock and bond market volatility rose. Persistent low interest rates also made

regular bonds a more attractive way to raise money than convertibles, which can potentially dilute the value of the issuer’s equity shares.

The fund’s relative performance was hindered modestly by its tilt toward convertible securities that have a balanced degree of equity sensitivity. Convertibles with greater sensitivity to stock market movements did well for the period, helping the benchmark modestly outdistance the fund.

During the 12 months, the fund reached its goal of holding about 30% of assets in non-U.S. securities. The year-ago figure was about 25%. The fund’s greater diversification is expected to

The fund expense ratio shown is from the prospectus dated March 25, 2015, and represents estimated costs for the current fiscal year. For
the fiscal year ended November 30, 2015, the fund’s expense ratio was 0.38%. This decrease from the estimated expense ratio reflects a
performance-based investment advisory fee adjustment. When the performance adjustment is positive, the fund’s expenses increase; when it

help the advisor manage risk and gain exposure to opportunities not available in the United States.

Returns from convertibles denominated in non-U.S. currencies were hurt as the value of many such currencies fell against the U.S. dollar. The dollar strengthened noticeably against most major currencies, including the euro, Japanese yen, British pound, Australian and Canadian dollars, and Swiss franc. The fund, though, uses currency hedging to take away the effects of currency fluctuations, whether positive or negative. As a result, the fund’s international holdings returned more than 6%, helping it to outperform peer funds.

Performance was restrained by the fund’s exposure to oil and gas companies in the energy sector, still battered by falling oil prices. The price of U.S.-produced oil fell 37% over the 12 months. However, energy-related convertibles made up just about 6% of the fund’s holdings, down from 16% two years ago. Information technology was the dominant sector; that helped results because IT stocks were among the market’s better performers during the period. The semiconductor industry did particularly well for the fund.

The fund’s long-term record continued to beat its yardsticks

The Convertible Securities Fund delivered an average annual return of 7.12% over the ten years ended November 30, 2015, besting both the Convertibles Composite Index (+6.65%) and the average return of peers (+5.84%).

The fund’s superior long-term record is evidence of the skill and experience of Oaktree Capital Management. Oaktree—which oversees about $100 billion in high-yield and distressed debt, convertibles, and other alternative assets—successfully managed the fund during an unusually turbulent ten-year period, when the global financial crisis dramatically reduced new issuance of convertibles. Interest in convertibles rebounded, but periods of volatility amid historically low interest rates have created unique challenges.

Oaktree has admirably steered the fund through these unusual crosscurrents. Importantly, the fund’s low expense ratio—about one-third of the peer fund average—helps the advisor pass on more of the fund’s returns to you.

A dose of discipline is crucial when markets become volatile

The developments over the past few months remind us that nobody can control the direction of the markets or reliably predict where they’ll go in the short term. However, investors can control how they react to unstable and turbulent markets.

During periods of market adversity, it’s more important than ever to keep sight of one of Vanguard’s key principles: Maintain perspective and long-term discipline. Whether you’re investing for yourself or on behalf of clients, your success is affected greatly by how you respond—or don’t respond—during turbulent markets. (You can read Vanguard’s Principles for Investing Success at vanguard.com/research.)

As I’ve written in the past, the best course for long-term investors is generally to ignore daily market moves and not make decisions based on emotion. This is also a good time to evaluate your portfolio and make sure your asset allocation is aligned with your time horizon, goals, and risk tolerance.

The markets are unpredictable and often confounding. Keeping your long-term plans clearly in focus can help you weather these periodic storms.

As always, thank you for investing with Vanguard.

Sincerely,

F. William McNabb III

Advisor’s Report

The investment strategy of Vanguard Convertible Securities Fund is to create a highly diversified global portfolio of convertible securities. The fund emphasizes

good call protection, and low to moderate conversion premiums. We believe these securities have a favorable balance of upside potential and downside risk. The fund underweights convertible preferred shares, which are riskier but may offer higher returns. We do, however, consider them part of our investable universe and make some use of them.

Importantly, the fund does not invest in common stocks or nonconvertible debt. We do not attempt market timing and therefore are fully invested, holding only a small amount of cash for potential investments. We believe that a portfolio of attractive, carefully selected convertible securities can produce equity-type returns with lower volatility and lower structural risk over long periods.

We are pleased to report that despite volatile market conditions, the fund posted a positive return, of 0.55%, for the 12 months ended November 30, 2015. Convertible securities benefited from the strength of underlying equities during market rallies while providing downside protection during times of volatility.

The investment environment

After a strong start to the period, convertible security valuations were affected by a combination of wider credit spreads and lower prices for the underlying equities. Several macroeconomic factors weighed heavily on the broad market from mid-June through the end of the period. Greece’s debt crisis, concerns over slowing growth in China, uncertainty about when the Federal Reserve would raise interest rates, and falling commodity prices led equity and credit markets to decline sharply. More narrowly focused markets, including convertible securities, also felt damaging effects. Despite these factors, global convertible bonds (on a U.S. dollar-hedged basis) remain a leading asset class for the calendar year to date.

The Convertible Securities portfolio remains highly sensitive to underlying equity performance as a result of convertibles’ historically low coupons in the current interest rate environment. The fund remains structurally conservative; 94% of its assets are in short- to intermediate-term bonds, defined as those with maturities or puts within seven years. Convertible preferred shares make up about 4% of the portfolio, a significant underweighting versus the benchmark index. We are comfortable with our current portfolio construction with its balance between equity and fixed income characteristics.

The new-issuance market over the period proved weaker than we anticipated. After a strong start to calendar year 2015, new issuance slowed considerably in the summer. It totaled $78.8 billion for the reporting period, with U.S. issuance of $38.8 billion slightly lagging non-U.S. issuance of $40 billion.

We believe there are three primary reasons for the lower issuance. First, volatility in the equity and credit markets dissuaded potential issuers. Second, uncertainty in the U.S. and global economies has made management teams hesitant to raise capital that may not be needed to fund internal growth

projects. Third, prolonged low interest rates have made nonconvertible debt issuance more attractive than a potentially dilutive convertible transaction. Until some of these obstacles are removed, we do not expect issuance to improve materially.

Our successes

The portfolio returns were broad-based. The top absolute individual contributors to performance were convertibles from Hologic, BioMarin Pharmaceutical, and Omnicare. Among industries, our security selection among semiconductor companies generated strong returns relative to the benchmark.

Our shortfalls

The fund had several winners and no meaningful detractors outside of oil and gas companies. Significant absolute individual detractors included SunEdison, Chesapeake Energy, and Iconix Brand Group. Among industries, our holdings in integrated oil, pharmaceutical, and communications equipment companies hurt relative performance.

The fund’s positioning

We remain fully invested in a highly diversified, well-balanced portfolio of convertible securities. At the end of the period, the fund held about one-third of its assets in securities issued outside the United States. The fund has an attractive current yield of 1.8% and an average credit quality of Ba3/BB–. The vast majority of the securities in the fund are performing well fundamentally and, importantly, are well-positioned from a credit perspective.

Our outlook remains positive. The convertible market remains technically sound. Demand is solid for most securities, especially for those issued by companies that have strong credit ratings. Fixed income investors find convertible securities attractive as they seek equity upside potential from fixed income assets and as equity investors seek to dampen stock market volatility. Convertibles will remain highly correlated with their underlying equities, but our emphasis on credit quality and intermediate-duration bonds will reduce that volatility.

Convertible Securities Fund

Notes to Financial Statements

Vanguard Convertible Securities 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.

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. Bonds, and temporary cash investments acquired over 60 days to maturity, are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Other temporary cash investments are valued at amortized cost, which approximates market 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 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.

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. Forward Currency Contracts: The fund enters into forward currency contracts to protect the value of securities and related receivables and payables against changes in future foreign exchange rates. The fund’s risks in using these contracts include movement in the values of the foreign currencies relative to the U.S. dollar and the ability of the counterparties to fulfill their obligations under the contracts. The fund mitigates its counterparty risk by entering into forward currency contracts only with a diverse group of prequalified counterparties, monitoring their financial strength, entering into master netting arrangements with its counterparties, and requiring its counterparties to transfer collateral as security for their performance. 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,

23

Convertible Securities Fund

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.

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

During the year ended November 30, 2015, the fund’s average investment in forward currency contracts represented 20% 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 (November 30, 2012–2015), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

6. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.06% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate equal to the higher of the federal funds rate or LIBOR reference rate plus an agreed-upon spread.

The fund had no borrowings outstanding at November 30, 2015, or at any time during the period then ended.

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

B. Oaktree Capital Management, L.P. provides investment advisory services to the fund for a fee calculated at an annual percentage rate of average net assets. The basic fee is subject to quarterly adjustments based on the fund’s performance for the preceding three years relative to a composite index weighted 70% Bank of America Merrill Lynch All US Convertibles Index and 30% Bank of America Merrill Lynch Global 300 Convertibles ex-US Index (hedged). For the year ended

24

Convertible Securities Fund

November 30, 2015, the investment advisory fee represented an effective annual basic rate of 0.34% of the fund’s average net assets before a decrease of $3,256,000 (0.17%) 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, 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 November 30, 2015, the fund had contributed to Vanguard capital in the amount of $153,000, 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.

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.

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 November 30, 2015, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Convertible Bonds	—	1,591,323	10,983
Convertible Preferred Stocks	—	75,279	—
Temporary Cash Investments	40,272	—	—
Forward Currency Contracts—Assets	—	16,938	—
Forward Currency Contracts—Liabilities	—	(154)	—
Total	40,272	1,683,386	10,983

E. At November 30, 2015, the fund had open forward currency contracts to receive and deliver currencies as follows. Unrealized appreciation (depreciation) on open forward currency contracts, except for Hong Kong, Singapore, and Taiwan dollar currency contracts, is treated as realized gain (loss) for tax purposes.

Refer to the Statement of Net Assets for currency abbreviations.

At November 30, 2015, counterparties had deposited in segregated accounts securities and cash with a value of $14,885,000 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.

During the year ended November 30, 2015, the fund realized net foreign currency losses of $9,457,000 (including the foreign currency component on sales of foreign currency denominated bonds), which decreased distributable net income for tax purposes; accordingly, such losses have been reclassified from accumulated net realized gains to undistributed net investment income.

Certain of the fund’s convertible preferred stock investments are treated as debt securities for tax purposes. During the year ended November 30, 2015, the fund realized gains of $25,000 from the sale of these securities, which are included in distributable net investment income for tax purposes; accordingly, such gains have been reclassified from accumulated net realized gains to undistributed net investment income.

26

Convertible Securities Fund

Certain of the fund’s convertible bond investments are in securities considered to be “contingent payment debt instruments,” for which any realized gains increase (and all or part of any realized losses decrease) income for tax purposes. During the year ended November 30, 2015, the fund realized net gains of $12,031,000 from the sale of these securities, which increased distributable net income for tax purposes; accordingly, such gains have been reclassified from accumulated net realized gains to undistributed net investment income.

The fund used a tax accounting practice to treat a portion of the price of capital shares redeemed during the year as distributions from realized capital gains. Accordingly, the fund has reclassified $10,591,000 from accumulated net realized gains to paid-in capital.

For tax purposes, at November 30, 2015, the fund had $17,006,000 of ordinary income and $18,615,000 of long-term capital gains available for distribution.

At November 30, 2015, the cost of investment securities for tax purposes was $1,737,234,000. Net unrealized depreciation of investment securities for tax purposes was $19,377,000, consisting of unrealized gains of $79,607,000 on securities that had risen in value since their purchase and $98,984,000 in unrealized losses on securities that had fallen in value since their purchase.

G. During the year ended November 30, 2015, the fund purchased $1,726,401,000 of investment securities and sold $1,930,452,000 of investment securities, other than temporary cash investments.

H. Capital shares issued and redeemed were:

	Year Ended November 30,
	2015	2014
	Shares	Shares
	(000)	(000)
Issued	10,764	18,911

Redeemed	(30,554)	(28,206)
Net Increase (Decrease) in Shares Outstanding	(7,085)	3,745

I. Management has determined that no material events or transactions occurred subsequent to November 30, 2015, that would require recognition or disclosure in these financial statements.

Report of Independent Registered
Public Accounting Firm

To the Board of Trustees and Shareholders of Vanguard Convertible Securities Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Convertible Securities Fund (the “Fund”) at November 30, 2015, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at November 30, 2015 by correspondence with the custodian and brokers, by agreement to the underlying ownership records of the transfer agent and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.

of the Internal Revenue Code.

The fund distributed $114,172,000 as capital gain dividends (20% rate gain distributions) to
shareholders during the fiscal year.

For nonresident alien shareholders, 100% of short-term capital gain dividends distributed by the fund
are qualified short-term capital gains.

The fund distributed $2,914,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 14.9% of investment income (dividend income plus short-term gains,
if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

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

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income, using actual prior-year figures and estimates for 2015. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

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

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

About Your Fund’s Expenses

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

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

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

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

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

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

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

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

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

Six Months Ended November 30, 2015
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Convertible Securities Fund	5/31/2015	11/30/2015	Period
Based on Actual Fund Return	$1,000.00	$942.43	$1.90
Based on Hypothetical 5% Yearly Return	1,000.00	1,023.11	1.98

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratio for that
period is 0.39%. 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 (183/365).

Glossary

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

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 Weighted Maturity. The average length of time until fixed income securities held by a fund reach maturity and are repaid. The figure reflects the proportion of fund assets represented by each security.

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.

Conversion Premium. The average percentage by which the weighted average market price of the convertible securities held by a fund exceeds the weighted average market price of their underlying common stocks. For example, if a stock is trading at $25 per share and a bond that is convertible into the stock is trading at a price equivalent to $30 per share of stock, the conversion premium is 20% ($5 ÷ $25 = 20%).

Credit Quality. Credit-quality ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Credit-quality ratings are obtained from S&P. “Not Rated” is used to classify securities for which a rating is not available. Not rated securities include a fund’s investment in Vanguard Market Liquidity Fund or Vanguard Municipal Cash Management Fund, each of which invests in high-quality money market instruments and may serve as a cash management vehicle for the Vanguard funds, trusts, and accounts. 

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.

32

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.

Market Exposure. A measure that reflects a fund’s security investments excluding any holdings in short-term reserves.

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.

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 194 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.
