LETTER FROM THE CHAIRMAN Fellow Shareholder, During the 12 months ended November 30, 2003, the stock market rebounded strongly from last year's bear-market lows. Convertible securities, which offer some of the upside potential of stocks and some of the risk-reducing properties of bonds, were particularly attractive to investors, who-- perhaps mindful of rebounds that had petered out in previous years--drove up the prices of these securities, generating total returns higher than those of common stocks. In this environment, Vanguard Convertible Securities Fund earned 28.1%, its best fiscal-year result in 12 years. [PICTURES OF JOHN J. BRENNAN] - ------------------------------------------------------- 2003 TOTAL RETURNS FISCAL YEAR ENDED NOVEMBER 30 - ------------------------------------------------------- VANGUARD CONVERTIBLE SECURITIES FUND 28.1% CS First Boston Convertibles Index 23.7 Average Convertible Securities Fund* 22.1 Wilshire 5000 Index 19.0 - ------------------------------------------------------- *Derived from data provided by Lipper Inc. As the table at left shows, your fund's total return (capital change plus reinvested distributions) was well above those of its main comparative measures--the unmanaged Credit Suisse First Boston Convertible Securities Index and the average mutual fund peer-- and about 9 percentage points higher than the return of the broad U.S. stock market, as measured by the Wilshire 5000 Total Market Index. The per-share components of your fund's total return--dividends and change in net asset value--appear on page 5. The fund's yield at fiscal year-end was 3.73%, 36 basis points lower than at the start of the period. STOCKS SURGED ON POSITIVE ECONOMIC AND FINANCIAL REPORTS The prospect of war with Iraq and a spate of weak economic reports depressed U.S. stock prices in the opening months of the fiscal year. 1 - -------------------------------------------------------------------------------- If you hold the fund in a taxable account, please see page 14 for a report on the fund's after-tax returns. - -------------------------------------------------------------------------------- Once the start of combat dissipated some uncertainties, however, investors' mood turned upbeat, igniting a robust stock market rally. In the fiscal year's final weeks, stocks were propelled by reports that productivity and manufacturing activity were growing rapidly, while profits at U.S. corporations rose nearly 30% in the third calendar quarter from their year-earlier levels. For the 12 months, the broad market, as measured by the Wilshire 5000 Index, returned 19.0%. Within market-capitalization ranges, gains were substantially similar for growth and value stocks (i.e., stocks that sport premium prices for their earnings growth potential versus those having bargain-basement price tags relative to earnings, book value, or other measures). A large divergence between small- and large-company stock returns, however, suggested that investors had a renewed interest in riskier stocks. The 36.3% return of the small-cap Russell 2000 Index was more than double the result of the large- and mid-cap Russell 1000 Index. Stock gains were equally impressive in many international markets, particularly those in the Pacific Rim nations and emerging-markets countries. For U.S.-based investors, the weakening of the dollar relative to most major currencies boosted returns from abroad. BOND INVESTORS WERE REWARDED FOR TAKING GREATER RISKS As in the stock market, the best returns in the bond market came from the riskiest securities. Returns of corporate bonds exceeded those of U.S. Treasury securities with comparable maturities, while below-investment-grade bonds posted spectacular results that topped the gain of the broad stock market. The Lehman Brothers High Yield Bond Index, which tracks the performance of bonds issued by companies with "junk" credit ratings, returned 27.9%. The yield of the benchmark 10-year Treasury note rose 12 basis points (0.12 percentage point) during the period to 4.33%. For the 12 months, the Lehman Aggregate Bond Index, a measure of the taxable investment-grade bond market, returned 5.2%, as rising interest income offset falling bond prices. The story was different among the shortest-maturity debt securities, whose yields are influenced more strongly by the Federal Reserve 2 - ------------------------------------------------------------------------------ MARKET BAROMETER AVERAGE ANNUAL TOTAL RETURNS PERIODS ENDED NOVEMBER 30, 2003 -------------------------------------- ONE THREE FIVE YEAR YEARS YEARS - ------------------------------------------------------------------------------ STOCKS Russell 1000 Index (Large-caps) 16.9% -4.9% 0.2% Russell 2000 Index (Small-caps) 36.3 8.5 8.0 Wilshire 5000 Index (Entire market) 19.0 -3.3 0.8 MSCI All Country World Index ex USA (International) 27.1 -2.3 0.7 - ------------------------------------------------------------------------------ BONDS Lehman Aggregate Bond Index 5.2% 7.9% 6.5% (Broad taxable market) Lehman Municipal Bond Index 6.7 7.2 5.7 Citigroup 3-Month Treasury Bill Index 1.1 2.4 3.6 ============================================================================== CPI Consumer Price Index 1.8% 2.0% 2.4% - ------------------------------------------------------------------------------ Board's actions than by market forces. In June, the Fed reduced its target federal-funds rate by 25 basis points to 1.00%, the lowest level since 1958. The yield of the 3-month Treasury bill, a fair proxy for money market interest rates, fell to 0.81% in mid-June, then rose modestly to end the fiscal year at 0.93%, 28 basis points lower than its year-ago level. YIELD SPREADS NARROWED, BENEFITING CONVERTIBLES The Convertible Securities Fund's 28.1% return, a stellar result in both absolute and relative terms, was bolstered by several factors. As hybrid securities with some characteristics of bonds and some of stocks, convertibles benefited from both the resurgence of stocks, particularly small-cap stocks, and the narrowing of the credit yield spread, as prices for riskier debt issues surged well ahead of those for investment-grade securities. (Convertibles tend to be issued by smaller companies with lower credit ratings, though several blue chips floated offerings in the past year.) In addition, the technology and telecommunications industries-- the very sectors that helped drag down your fund's performance last fiscal year--boosted the fund's absolute returns during fiscal 2003. Compared with its benchmarks, however, your fund was light in these sectors earlier in the year, which dampened performance relative to the index during the first six months. Most important, the fund's investment advisor, Oaktree Capital Management, added value through its security selection in several sectors, as the prices of some of its long-term holdings skyrocketed. For details on individual securities and fund performance, see the Report from the Advisor, which begins on page 6. 3 THE FUND HAS DELIVERED SOLID LONG-TERM PERFORMANCE Of course, a 28.1% one-year return is exceptional and should not be expected consistently from any fund, whether it invests in convertibles or another asset class. But the fund has also done well over longer periods. As the accompanying table shows, over the past decade, your fund delivered a solid annualized return of 8.7%. This result was roughly on par with those of its comparative standards--slightly outpacing the gain of the average competing fund but slightly lagging that of the benchmark index--and not far below the return of common stocks. However, your fund generated this solid return with lower volatility than any of these measures. Unlike some fund peers that will on occasion invest in other asset classes, your fund invests almost exclusively in convertible bonds and some convertible preferred stocks. In addition, the advisor carefully screens companies for creditworthiness. We believe that the Convertible Securities Fund will continue to perform competitively because of both the investment skills of the fund advisor and our cost advantage. In fact, Vanguard's expense ratios are typically just a fraction of those of other fund companies, which has two key implications. First, more of our funds' returns go to shareholders. Second, our competitors must generate gross returns higher than ours to match our net returns--a difficult hurdle to surmount year after year. The cost of investing--unlike other factors, such as the performance of the financial markets--is within your control. (A comparison of your fund's cost with the average cost of its competitors is provided on page 15.) - ----------------------------------------------------------------------- TOTAL RETURNS TEN YEARS ENDED NOVEMBER 30, 2003 - ----------------------------------------------------------------------- AVERAGE FINAL VALUE OF ANNUAL A $10,000 RETURN INITIAL INVESTMENT - ----------------------------------------------------------------------- Convertible Securities Fund 8.7% $23,051 CS First Boston Convertibles Index 9.1 23,930 Average Convertible Securities Fund 8.4 22,494 Wilshire 5000 Index 10.3 26,648 - ----------------------------------------------------------------------- BALANCE NEVER GOES OUT OF STYLE The past several years have been a roller-coaster ride for investors, as one of the longest bull markets in history was followed by one of the worst bear markets for stocks, which in turn underwent a remarkable resurgence this year. Although probably no investor escaped unscathed, those who were diversified across and within asset classes weathered 4 the ride better than those who were not. Volatile markets reinforce the virtue of the time-honored principle of balance--holding stocks, bonds, and short-term reserves in allocations appropriate for your goals, time horizon, and risk tolerance. Because no one can accurately predict what the future will bring, building and holding a balanced portfolio is the most prudent course. Vanguard Convertible Securities Fund can play a valuable role in such a portfolio. I feel compelled to close this letter with an assurance that the reports of late-trading and market-timing at some competing investment management firms are as shocking--and upsetting--to us as they no doubt are to you. Vanguard has policies and procedures in place to identify and deter such behavior. More important, I believe that Vanguard shareholders can be confident both in the integrity of our excellent crew and in the benefits provided by our client-owned corporate structure--a structure that perfectly aligns our day-to-day efforts with your long-term financial goals. Thank you for entrusting us with your assets. Sincerely, /S/JOHN J. BRENNAN John J.

For the 12 months, the fund earned 28.1%, outperforming its primary benchmark, the CS First Boston Convertibles Index (+23.7%), as well as the Goldman Sachs/Bloomberg U.S. Convertible 100 Index (+16.0%), another widely followed convertibles benchmark. The fund also outperformed the Standard & Poor's 500 Index and most of the widely followed bond indexes. Our outperformance of the S&P 500 was largely a function of, first, our exposure to convertibles from small- and mid-capitalization companies and, second, the tightening of credit spreads, which boosted the valuations of convertible securities. This performance advantage versus the S&P 500 should not be considered sustainable, as convertibles normally lag in an equity advance. THE INVESTMENT ENVIRONMENT The second half of fiscal 2003 repeated many of the trends from the first half of the year. The two most dominant themes were the continuation of credit-spread tightening and the very robust issuance of new convertible securities. As discussed in May's semiannual report, the tightening was primarily a result of investors' becoming more optimistic about both the economy and corporate fundamentals. Fundamentals have improved as corporations enhance their balance sheets through transactions such as refinancing at lower rates and longer maturities. New convertible issuance was also an important factor during fiscal 2003, as the year produced the second-highest dollar volume on record: $82.3 billion from 252 deals. This compares with the prior year's total of 115 deals raising $52.3 billion. - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- Significant convertible issuers in fiscal 2003 included General Motors ($4.0 billion), Wells Fargo ($3.0 billion), American Express ($2.0 billion), 6 Schlumberger ($1.4 billion), and Walt Disney ($1.3 billion). Other deals we especially liked came from Freeport-McMoRan Copper & Gold, Valeant Pharmaceuticals International, Primus Telecom, and Continental Airlines. While the dollar volume of new deals did not set a record, the number of new securities did eclipse the 208 convertibles issued in 2001. The past year's issuance was well diversified by industry, issuer, and credit quality. An extraordinarily high proportion came in the form of coupon-bearing convertible bonds--approximately 85%, compared with the previous five-year average of 42%. We always prefer convertible bonds over other convertible structures, and thus we welcome this trend. Demand for convertibles remained quite strong throughout the year, as investors appreciated the securities' benefits: the potential for appreciation when their underlying common stocks move upward; relative protection when their underlying stocks decline; higher current yields; and diversification. The demand for attractively priced new deals currently exceeds supply, and thus many deals are on an allocation basis. THE FUND'S SUCCESSES Our absolute performance continued to be influenced by the tightening of credit spreads, but most of our performance advantage over the fund's benchmarks during fiscal 2003 came from security selection. In particular, we saw outperformance in our overweighted positions and in many of our small- and mid-cap convertibles. (Small- and mid-cap stocks posted significant gains during 2003, certainly driving up the prices of many convertibles.) Some of our top-performing issues included Freeport-McMoRan, RF Micro Devices, Nextel Communications, Navistar International, and Teva Pharmaceutical. We also benefited from our aggressive buying around the middle of the year. This was a period of relative price weakness caused by a dramatic oversupply of new convertibles, overpricing of some of these deals, and adjustment to the new dividend tax environment. This last factor was quite disruptive to the market as corporations reevaluated their common dividend policies and, in many cases, declared their first dividends or announced significant dividend increases. For companies with outstanding convertibles, any significant increase in common dividends diminishes the convertible's yield advantage and reduces the intrinsic value of the security. The impact on our holdings from this factor was minimal, but we took advantage of buying opportunities as they occurred. 7 THE FUND'S SHORTFALLS While we are very pleased with the Convertible Securities Fund's return for fiscal 2003, our underweighting of the tech/telecom area earlier in the year proved to be a drag on our relative results. With spreads tightening, these highly depressed convertibles produced some dramatic gains. The fund was also underweighted in the automobile industry, specifically in the Ford 6.50% convertible preferred, which did well and was the heaviest-weighted issue in the CS First Boston Convertibles Index. OUR POSITION As we enter the new year, we are slightly accelerating our normal sell strategy because the prices of many convertibles, especially those from small-cap technology and telecom firms, have advanced to 140%-160% of par. We are redeploying our sale proceeds into more balanced, higher-yielding issues that will provide more downside protection in the event of a market pullback. The convertible market's weighted-average delta (i.e., degree of participation in the appreciation of underlying stocks) is higher than it was a year or two ago, due to the significant rally in equities. Not counting a modest cash reserve, our portfolio remains fully invested, with an approximate mix of 91% convertible bonds and 9% convertible preferreds. We are very comfortable with the credit profile of the portfolio and remain optimistic about the near-term outlook for the convertible securities market.

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. - -------------------------------------------------------------------------------- 11 GLOSSARY OF INVESTMENT 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% ($54$25520%). - ------------------------------------------------------------------------------- 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. - ------------------------------------------------------------------------------- 12 PERFORMANCE SUMMARY AS OF 11/30/2003 All of the returns in this report represent past performance, which cannot be used to predict future returns that may be achieved by the fund. Note, too, that both share price and return can fluctuate widely. An investor's shares, when redeemed, 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 redemption of fund shares.

Note: See Financial Highlights table on page 22 for dividend and capital gains information. 13 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 the reduced tax rates on ordinary income (including qualified dividend income) and short-term capital gains that became effective as of January 1, 2003, and on long-term capital gains realized on or after May 6, 2003. Qualified dividend income is based on estimates for calendar year 2003. (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 indicate how it will perform in the future. - -------------------------------------------------------------------------------- AVERAGE ANNUAL TOTAL RETURNS PERIODS ENDED NOVEMBER 30, 2003 ONE YEAR FIVE YEARS TEN YEARS ------------------------------------- CONVERTIBLE SECURITIES FUND Returns Before Taxes 28.07% 9.79% 8.71% Returns After Taxes on Distributions 26.38 7.29 5.50 Returns After Taxes on Distributions and Sale of Fund Shares 18.02 6.83 5.42 - -------------------------------------------------------------------------------- 14 ABOUT YOUR FUND'S EXPENSES All mutual funds have operating expenses. These expenses 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 net assets. This figure is known as the expense ratio. A HYPOTHETICAL EXAMPLE We believe it is important for you to understand the impact of costs on your investment. The following example illustrates the costs that you would incur over a 12-month period if you invested $10,000 in the fund, using the fund's actual return and operating expenses for the fiscal year ended November 30, 2003. The cost in dollars is calculated by applying the expense ratio to the average balance in the hypothetical account. For comparative purposes, we also list the average expense ratio for the fund's peer group, which is derived from data provided by Lipper Inc. - -------------------------------------------------------------------------------- COST OF $10,000 FUND PEER GROUP* INVESTMENT IN FUND EXPENSE RATIO EXPENSE RATIO - -------------------------------------------------------------------------------- Convertible Securities Fund $96 0.84% 1.49% - -------------------------------------------------------------------------------- *Average Convertible Securities Fund. The calculation assumes no shares were sold. Your actual costs may have been higher or lower, depending on the amount of your investment and your holding period. Peer-group ratio captures data through year-end 2002. You can find more information about the fund's expenses, including annual expense ratios for the past five years, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the fund's prospectus. The prospectus presents hypothetical shareholder costs over various time periods based upon a $10,000 investment and a return of 5% a year. This standardized example, which appears in all mutual fund prospectuses, may be useful to you in comparing the costs of investing in different funds. 15 FINANCIAL STATEMENTS AS OF 11/30/2003 STATEMENT OF NET ASSETS This Statement provides a detailed list of the fund's holdings, including each security's market value on the last day of the reporting period. 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 (87.6%) - --------------------------------------------------------------------------- AUTO & TRANSPORTATION (7.3%) Continental Airlines, Inc. 4.50%, 2/1/2007 $ 19,400 $ 17,169 (1)5.00%, 6/15/2023 3,815 4,874 General Motors Corp. 4.50%, 3/6/2032 192 4,825 Lear Corp. 0.00%, 2/20/2022 17,855 9,151 Mesa Air Group Inc.

It also presents the Total Return and shows net investment income and expenses as percentages of average net assets. These data will help you assess: the variability of the fund's net income and total returns from year to year; the relative contributions of net income and capital gains to the fund's total return; how much it costs to operate the fund; and the extent to which the fund tends to distribute capital gains. The table also shows the Portfolio Turnover Rate, a measure of trading activity. A turnover rate of 100% means that the average security is held in the fund for one year.

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 year ended November 30, 2003, the investment advisory fee represented an effective annual basic rate of 0.38% of the fund's average net assets before an increase of $675,000 (0.13%) 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 November 30, 2003, the fund had contributed capital of $123,000 to Vanguard (included in Other Assets), representing 0.02% of the fund's net assets and 0.12% of Vanguard's capitalization. The fund's trustees and officers are also directors and officers of Vanguard. 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) D. The fund's custodian bank has agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the year ended November 30, 2003, custodian fee offset arrangements reduced expenses by $6,000. 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. Certain of the fund's convertible preferred stock investments are treated as debt securities for tax purposes. During the year ended November 30, 2003, the fund realized gains of $435,000 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. For tax purposes, at November 30, 2003, the fund had $6,561,000 of ordinary income available for distribution. The fund had available realized losses of $16,034,000 to offset future net capital gains through November 30, 2010. At November 30, 2003, net unrealized appreciation of investment securities for tax purposes was $64,930,000, consisting of unrealized gains of $68,364,000 on securities that had risen in value since their purchase and $3,434,000 in unrealized losses on securities that had fallen in value since their purchase. F. During the year ended November 30, 2003, the fund purchased $1,028,216,000 of investment securities and sold $626,776,000 of investment securities, other than temporary cash investments. G. The market value of securities on loan to broker/dealers at November 30, 2003, was $104,973,000, for which the fund held cash collateral of $106,795,000. 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. 24 REPORT OF INDEPENDENT AUDITORS To the Shareholders and Trustees 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, 2003, 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 auditing standards generally accepted in the United States of America, which 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, 2003 by correspondence with the custodian, provide a reasonable basis for our opinion.

The contribution limits on IRAs were recently raised, making these tax-deferred accounts more powerful options for retirement savers. Here's how you can exploit your IRA--and improve your chances of having the retirement of your dreams. CONTRIBUTE THE MAXIMUM AMOUNT EACH YEAR It may be an obvious point, but if you invest as much in your IRA as the law allows--currently $3,000 per tax year if you are under age 50 and $3,500 if you are age 50 or over--you will increase the odds of meeting your retirement goals. "Max out" every year you can. MAKE IT AUTOMATIC Put your IRA on autopilot by taking advantage of Vanguard's Automatic Investment Plan. Your IRA contributions will be deducted from your bank account on a schedule of your choosing, making retirement investing a healthy habit. CONSIDER COST The owners of low-cost investments keep a larger portion of their gross returns than the owners of high-cost investments. Over the long term, avoiding costlier mutual funds and brokerage commissions could significantly boost your retirement savings. Our low costs are one reason a Vanguard IRA(R) is such a smart choice. REQUEST A DIRECT ROLLOVER WHEN YOU CHANGE JOBS Don't spend your retirement assets before you've retired. When you change jobs, roll your 401(k) or other employer-sponsored retirement plan assets directly into your IRA. If you have questions about your IRA, want to transfer an IRA from another institution to Vanguard, or need help with any other IRA transaction, call our Retirement Resource Center at 1-800-205-6189 or visit VANGUARD.COM. You can open or fund your IRA on our website and have a confirmation in your hand within minutes. 27 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.
