As you might expect, hybrid investments posted results midway between those of stocks and bonds during the six months ended May 31, 2004. Vanguard Convertible Securities Fund returned 3.1%, which was lower than the results of its comparative measures. [PICTURE OF JOHN J.

The adjacent table shows total returns (capital gains plus reinvested distributions) for the fund and three benchmarks: the unmanaged Credit Suisse First Boston Convertible Securities Index, the average mutual fund peer, and the broad U.S. stock market, as measured by the Dow Jones Wilshire 5000 Composite Index. The fund's starting and ending share prices and distributions to shareholders are shown on page 4. As of May 31, the fund's yield was 2.72%, 101 basis points (1.01 percentage points) lower than at the start of the period. As you know, on May 14 the Convertible Securities Fund was closed to new accounts and to additional purchases for existing accounts. During the previous 12 months, fund assets had more than doubled as a result of both market appreciation and new investments. Such rapid asset growth has the potential to hamper an investment advisor's ability to put new cash to work effectively. The challenge is even greater when the target market is a rarefied one, such as convertibles, and when the investment advisor prefers a disciplined, bottom-up approach to security 1 selection--as does Oaktree Capital Management, your fund's advisor. This is why, to protect current shareholders, the fund's board of trustees decided to close the Convertible Securities Fund. STOCKS ROSE BUT WERE DOGGED BY INFLATIONARY FEARS The fiscal half-year opened with strong returns in the domestic and foreign stock markets as the bull market of 2003 spilled into January. As the economic expansion gathered momentum, however, concern about inflation and rising oil prices weighed on stock prices. Unrest in the Middle East and growing global demand for oil pushed the per-barrel price past $40, a level not seen since early in the Iran-Iraq War more than 20 years ago. In April, stock markets retreated across the board. For the six months, the broad U.S. stock market, as measured by the Dow Jones Wilshire 5000 Index, returned 6.4%. That return was mirrored by the mid- to large-capitalization stocks in the Russell 1000 Index; however, the Russell 2000 Index, a proxy for small-cap stocks, trailed with a 4.5% gain. Across the market-cap spectrum, value-oriented stocks (those that generally trade at below-market valuations relative to their book values and other fundamental measures) posted better results than growth stocks (those expected to produce above-average earnings growth). For investors in the United States, international stocks continued to provide even better returns than the domestic market, a result of the relative weakness of the U.S. dollar and the solid gains of stocks in Europe and Japan. STRENGTHENING ECONOMY PUSHED BOND YIELDS HIGHER In the fixed income markets, interest rates rose sharply in April in response to signs of higher inflation. Over the six months ended May 31, the yield of the benchmark 10-year U.S. Treasury note increased 32 basis points to 4.65%. The Lehman Brothers Aggregate Bond Index, which covers the taxable investment-grade bond market, returned just 0.6%, with income offsetting the price drop that accompanies rising rates for bonds. The yields of many short-term issues also rose in expectation of actions by the Federal Reserve Board to boost interest rates, but for the shortest- 2 - -------------------------------------------------------------------------------- MARKET BAROMETER TOTAL RETURNS PERIODS ENDED MAY 31, 2004 --------------------------- SIX ONE FIVE MONTHS YEAR YEARS* - -------------------------------------------------------------------------------- STOCK Russell 1000 Index (Large-caps) 6.4% 18.9% -1.0% Russell 2000 Index (Small-caps) 4.5 30.3 6.7 Dow Jones Wilshire 5000 Index 6.4 20.5 -0.5 (Entire market) MSCI All Country World Index ex USA (International) 9.6 33.2 1.4 - -------------------------------------------------------------------------------- BOND Lehman Aggregate Bond Index 0.6% -0.4% 6.8% (Broad taxable market) Lehman Municipal Bond Index -0.2 0.0 5.5 Citigroup 3-Month Treasury Bill Index 0.5 1.0 3.2 ================================================================================ CPI Consumer Price Index 2.5% 3.1% 2.6% - -------------------------------------------------------------------------------- *Annualized. term securities--those held by money market funds--yields were relatively stable. These securities respond more to Fed actions than to market expectations. The yield of the 3-month Treasury bill, a proxy for money market rates, started the half-year at 0.93% and ended at 1.06%. A BELL-SHAPED PERFORMANCE CURVE FOR YOUR FUND On the way to its 3.1% six-month return, the Convertible Securities Fund experienced considerable volatility. The fund made strong gains in December and January, but gave up some of those gains during the last two months of the period. To an extent, that pattern mirrored what was happening in both the stock and bond markets. Convertibles, by their nature, are linked to the performance of the issuers' common stocks. Your fund lagged the average return of competitors by 0.9 percentage point, a gap largely attributable to the nature of its holdings. As its name implies, the fund invests almost exclusively in convertible bonds and convertible preferred stocks. This is in sharp contrast to many of its peers. Indeed, according to fund-tracker Morningstar, the average convertibles fund at the end of 2003 had 13% of its assets in common stocks. Your fund's disciplined focus on hybrid securities can place it at a disadvantage when common stocks outperform other asset classes, and particularly when small-cap growth stocks are lagging the broad equity market, as they did during the fiscal half-year. Convertibles are typically issued by small, growing companies. The fund lagged its benchmark index by a wider margin of 1.5 percentage points, largely as a result of security selection. We do not read too much into a track record of just six months, whether the record is stellar or subpar. In three of the past four fiscal years, your fund outpaced its benchmark by much wider margins. And the fund has outperformed its 3 average peer over the past decade. We believe that the proven skills of the investment advisor, together with Vanguard's low costs, will help the fund continue to post competitive returns over the long run. For more information about the fund's performance and its individual securities, please see the Report from the Advisor that begins on page 5. NEW CONCERNS, SAME ADVICE Not long ago, in the punishing bear market, we were counseling investors not to give up on stocks. Today, investor apprehension seems to have relocated to the bond market, but our message is the same. The best response to the ever-changing risks of the financial markets is to develop a plan and stick with it. A sensible plan includes a mix of stock, bond, and money market funds weighted in proportions appropriate to your unique circumstances. When a tough period strikes one asset class, some of the pain can be offset by better performance in another. Over time, this simple, balanced approach puts you in a good position to meet your financial goals. Vanguard Convertible Securities Fund, with its hybrid nature, can play a useful role, adding another layer of diversification to such a balanced portfolio. Thank you for entrusting your assets to us. Sincerely, /S/JOHN J. BRENNAN John J. Brennan CHAIRMAN AND CHIEF EXECUTIVE OFFICER JUNE 14, 2004 - -------------------------------------------------------------------------------- YOUR FUND'S PERFORMANCE AT A GLANCE NOVEMBER 30, 2003-MAY 31, 2004 DISTRIBUTIONS PER SHARE ------------------------ STARTING ENDING INCOME CAPITAL SHARE PRICE SHARE PRICE DIVIDENDS GAINS - -------------------------------------------------------------------------------- Convertible Securities Fund $13.05 $13.22 $0.23 $0.00 - -------------------------------------------------------------------------------- 4 REPORT FROM THE ADVISOR Vanguard Convertible Securities Fund achieved a reasonable absolute return during the first half of fiscal 2004, although our 3.1% gain fell slightly short of the 4.6% returned by our primary benchmark, the CS First Boston Convertibles Index. This shortfall was due to the underperformance of a few overweighted positions in the latter part of the six-month period. The absence from the fund of a few of the index's top-weighted holdings was also a factor, since these securities performed better than expected, especially toward the end of the period. Overall, though, we are pleased with the fund's result during what was a very volatile market environment. THE INVESTMENT ENVIRONMENT Fiscal 2004 began where fiscal 2003 left off, with positive investor sentiment for equities and lower interest rates combining to lift the prices of most convertible securities. The beginning of the period was very positive for most equities, with the Nasdaq Composite and Russell 2000 Indexes, in particular, advancing strongly. During this time, convertibles from technology and telecommunications firms were the top performers, with names like Lucent Technologies, Nortel Networks, and Juniper Networks leading the way. Investors also exhibited a preference for small-capitalization companies, and speculative-grade convertibles easily bested the investment-grade sector. On the fixed income side, interest rates declined slightly while credit spreads remained quite narrow; these factors boosted the prices of many convertibles. Nearly all of our return for the fiscal half-year came while this favorable environment existed. - -------------------------------------------------------------------------------- INVESTMENT PHILOSOPHY The advisor believes that a reasonable level of current income and long-term growth in capital can be achieved by investing in a broadly diversified group of convertible securities that provide attractive combinations of current income and potential for price appreciation from their convertibility into common stock. - -------------------------------------------------------------------------------- However, the surge in investor optimism was short-lived, as a variety of negative factors began to affect the financial markets beginning in March: Interest rates rose, credit spreads increased, 5 oil prices increased to all-time highs, and the threat of terrorism intensified. These and other concerns caused a significant retreat in investor sentiment and had a negative effect on all convertibles, including most of our holdings. Despite this roller-coaster investing environment, your fund performed reasonably well, as our selling discipline and careful new-issue selection allowed us to avoid several unfavorable situations. Even with the negative market overtones, demand for convertible securities remained strong in recent months, with interest coming from a wide variety of investors. As a result of the demand, we found the pricing of many new convertibles unattractive in terms of both yield and conversion premiums. The size of the average new issue also declined, as very few large-cap companies issued convertibles. On the positive side, call protection became quite generous, and many convertibles provided short- to intermediate-dated put features. In addition, dividend-protection language became standard in response to the large number of companies initiating or increasing their dividends on common stock. This language is beneficial to convertibles investors because dividend increases on the underlying common stock can have a negative impact on the valuation of a convertible security. While we declined to participate in many new deals, we did invest in offerings from Fisher Scientific International, Freeport-McMoRan Copper & Gold, CP Ships, and Chesapeake Energy. We expect the issuance of new convertible securities to be moderate during the next few months. THE FUND'S SUCCESSES Some of our top performers were convertibles from Fisher Scientific, Celgene, J.C. Penney, and American Tower. Fisher is our top-weighted holdings, and we remain very positive about its underlying equity story; we enjoy balanced convertible exposure to it through our investments in both of the firm's convertible bonds. Other securities that performed relatively well over the six months include Royal Caribbean Cruises, Reliant Resources, and Flir Systems. THE FUND'S SHORTFALLS Several investments had disappointing results, primarily in the latter half of the period, as negative developments affected their value. 6 One high-profile disappointment was our position in the Nortel 4.25% converts, which mature in September 2008. These bonds declined after the company announced problems in its accounting practices and fired its CEO and CFO. Valeant Pharmaceuticals International declined after reporting lackluster earnings. The fund's limited airline industry exposure also was unrewarding, as the escalating price of oil hurt airlines' near-term profitability. We continue to believe in American Airlines and Continental Airlines as long-term investments. OUR POSITION As usual, outside of a small short-term reserve, the portfolio consists entirely of convertibles--in a mix of 83% convertible bonds and 11% convertible preferreds--with no common stocks or other nonconvertible securities as of the end of the period. We remain positive about the investing environment and believe we are well positioned to continue to achieve the fund's objectives.

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 QUALITY. An indicator of credit risk, this figure is the average of the ratings assigned to a fund's holdings by credit-rating agencies. The agencies make their judgment after appraising an issuer's ability to meet its obligations. Quality is graded on a scale, with Aaa or AAA indicating the most creditworthy bond issuers. - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- 9 GLOSSARY OF INVESTMENTS TERMS (CONTINUED) - -------------------------------------------------------------------------------- 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%. 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. - -------------------------------------------------------------------------------- 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 convertible into the stock is trading at a price equivalent to $30 per share of stock, the conversion premium is 20% ($5 / $25 = 20%). - -------------------------------------------------------------------------------- EXPENSE RATIO. The percentage of a fund's average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors. - -------------------------------------------------------------------------------- FOREIGN HOLDINGS. The percentage of a fund's net assets represented by securities of companies based outside the United States. - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- 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). - -------------------------------------------------------------------------------- YIELD. A snapshot of a fund's income from interest and dividends. The yield, expressed as a percentage of the fund's net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. - -------------------------------------------------------------------------------- 10 PERFORMANCE SUMMARY AS OF 5/31/2004 All of the returns in this report represent past performance, which is not a guarantee of future results that may be achieved by the fund. (For the most recent performance, which may be higher or lower than that cited, visit our website at www.vanguard.com.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor's shares, when sold, could be worth more or less than their original cost. The returns shown do not reflect taxes that a shareholder would pay on fund distributions or on the sale of fund shares.

All mutual funds have operating 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 table below illustrates your fund's costs in two ways: * 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." * Hypothetical 5% 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 return of 5% before expenses during the period shown, but that the expense ratio is unchanged. In this case--because the return used is not the fund's actual return--the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund's costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds. - -------------------------------------------------------------------------------- SIX MONTHS ENDED MAY 31, 2004 BEGINNING ENDING EXPENSES CONVERTIBLE ACCOUNT VALUE ACCOUNT VALUE PAID DURING SECURITIES FUND 11/30/2003 5/31/2004 PERIOD* - -------------------------------------------------------------------------------- Actual Fund Return $1,000 $1,031 $3.61 Hypothetical 5% Return 1,000 1,046 3.63 - -------------------------------------------------------------------------------- *Expenses are equal to the fund's annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year, then divided by 366. Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. They do not include your fund's low-balance fee, described in the prospectus. If this fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a "sales load." 12 - ------------------------------------------------------------- ANNUALIZED EXPENSE RATIOS: YOUR FUND COMPARED WITH ITS PEER GROUP AVERAGE CONVERTIBLE SECURITIES FUND FUND - ------------------------------------------------------------- Convertible Securities Fund 0.71% 1.64%* - ------------------------------------------------------------- Peer-group expense ratio is derived from data provided by Lipper Inc. and captures information through year-end 2003.

Securities are grouped and subtotaled by asset type (common stocks, bonds, etc.) and by industry sector. Other assets are added to, and liabilities are subtracted from, the value of Total Investments to calculate the fund's Net Assets. Finally, Net Assets are divided by the outstanding shares of the fund to arrive at its share price, or Net Asset Value (NAV) Per Share. At the end of the Statement of Net Assets, you will find a table displaying the composition of the fund's net assets. Because all income and any realized gains must be distributed to shareholders each year, the bulk of net assets consists of Paid-in Capital (money invested by shareholders). The amounts shown for Undistributed Net Investment Income and Accumulated Net Realized Gains usually approximate the sums the fund had available to distribute to shareholders as income dividends or capital gains as of the statement date, but may differ because certain investments or transactions may be treated differently for financial statement and tax purposes. Any Accumulated Net Realized Losses, and any cumulative excess of distributions over net income or net realized gains, will appear as negative balances. Unrealized Appreciation (Depreciation) is the difference between the market value of the fund's investments and their cost, and reflects the gains (losses) that would be realized if the fund were to sell all of its investments at their statement-date values. - -------------------------------------------------------------------------------- FACE MARKET AMOUNT VALUE* CONVERTIBLE SECURITIES FUND (000) (000) - -------------------------------------------------------------------------------- CONVERTIBLE BONDS (83.4%) - -------------------------------------------------------------------------------- AUTO & TRANSPORTATION (9.9%) American Airlines 4.25%, 9/23/2023 $ 16,345 $ 14,751 Continental Airlines, Inc. 4.50%, 2/1/2007 17,300 12,802 (1) 5.00%, 6/15/2023 1,240 1,018 CP Ships Ltd.

SEE ACCOMPANYING NOTES, WHICH ARE AN INTEGRAL PART OF THE FINANCIAL STATEMENTS. 20 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. A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements. 1. SECURITY VALUATION: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 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. 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 materially affected by events occurring before the fund's pricing time but after the close of the securities' primary markets, are valued by methods deemed by the board of trustees to represent fair value. 2. REPURCHASE AGREEMENTS: The fund, along with other members of The Vanguard Group, transfers uninvested cash balances into a pooled cash account, which is invested in repurchase agreements secured by U.S. government securities. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal; however, in the event of default or bankruptcy by the other party to the agreement, retention of the collateral may be subject to legal proceedings. 3. FEDERAL INCOME TAXES: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements. 4. DISTRIBUTIONS: Distributions to shareholders are recorded on the ex-dividend date. 5. OTHER: Dividend income is recorded on the ex-dividend date. Security transactions are accounted for on the date the 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. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. B. Oaktree Capital Management, LLC, 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 the Credit Suisse First Boston Convertible Securities Index. For the six months ended May 31, 2004, the investment advisory fee represented an effective annual basic rate of 0.36% of the fund's average net assets before an increase of $442,000 (0.09%) based on performance. C. The Vanguard Group furnishes at cost corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At May 31, 2004, the fund had contributed capital of $166,000 to Vanguard (included in Other Assets), representing 0.02% of the fund's net assets and 0.17% of Vanguard's capitalization. The fund's trustees and officers are also directors and officers of Vanguard. 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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. The fund's tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at November 30, 2003, the fund had available realized losses of $16,034,000 to offset future net capital gains through November 30, 2010. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending November 30, 2004; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above. At May 31, 2004, net unrealized appreciation of investment securities for tax purposes was $12,183,000, consisting of unrealized gains of $44,765,000 on securities that had risen in value since their purchase and $32,582,000 in unrealized losses on securities that had fallen in value since their purchase. E. During the six months ended May 31, 2004, the fund purchased $737,419,000 of investment securities and sold $522,401,000 of investment securities, other than temporary cash investments. F. The market value of securities on loan to broker/dealers at May 31, 2004, was $222,828,000, for which the fund held cash collateral of $229,766,000. The fund invests cash collateral received in repurchase agreements, and records a liability for the return of the collateral, during the period the securities are on loan. 22 INVESTING IS FAST, EASY, AND SECURE ON VANGUARD.COM If you're like many Vanguard investors, you believe in planning and taking control of your own investments.
