November 17, 2004 Christian Sandoe, Esq. Division of Investment Management U.S. Securities and Exchange Commission via electronic filing 450 Fifth Street, N.W., Fifth Floor Washington, D.C. 20549 Re: Vanguard Convertible Securities Fund Dear Mr. Sandoe: The following responds to your comments of November 15, 2004 on the post-effective amendment of the registration statement of Vanguard Convertible Securities Fund. You commented on PEA number 27 that was filed on October 1, 2004 pursuant to Rule 485(a). COMMENT 1: PROSPECTUS - PRIMARY INVESTMENT STRATEGIES COMMENT: Vanguard defines convertible securities to include corporate bonds and preferred stocks that are convertible into common stock, as well as debt securities with warrants or common stock attached. How do the debt securities with warrants or common stock attached fit the definition of convertible securities if these debt securities are not technically convertible? RESPONSE: The securities in question are equity-linked debt securities. Given that they are fixed income instruments with the option to gain equity exposure via the warrants or detachable stock, they have economic characteristics substantially similar to the other securities held by the fund. COMMENT 2: PROSPECTUS - PRIMARY RISKS COMMENT: Sector risk is listed as a primary risk, but no specific sectors are listed. Please provide more specific information regarding these sectors. RESPONSE: We are removing the sector risk bullet from the list of primary risks in the fund profile, as well as from the Item 4 disclosure since there are no specific sectors at this time that present a primary risk to investors in the fund. This disclosure was appropriate a few years ago when tech stocks were very prevalent, but is no longer appropriate and should be deleted. COMMENT 3: PROSPECTUS - PRIMARY RISKS COMMENT: In the Credit Risk section Vanguard says, "Companies that issue convertible securities are often small to medium size, and they often have low credit ratings." Accordingly, there should be a statement describing small and mid-cap market risk. RESPONSE: We do not plan to add a statement describing small and mid-cap market risk. The fund primarily owns debt securities that are convertible to equity securities. It is true that the companies issuing these securities are often small to medium size. However, since the debt securities are very rarely, if ever, held to conversion, shareholders are seldom, if ever, exposed to the market-cap risks of the equity securities. The real risk to fund shareholders based on the size of the issuers is the low credit rating of these issuers. Accordingly, we think the existing disclosure is appropriate. COMMENT 4: - PROSPECTUS - AVERAGE ANNUAL TOTAL RETURN TABLE COMMENT: Fix the date in the first footnote to the table. RESPONSE: We have fixed the date. COMMENT 5: - PROSPECTUS - AVERAGE ANNUAL TOTAL RETURN TABLE COMMENT: A fund cannot use a brand new index as a broad-based index. RESPONSE: The Merrill Lynch All US Convertibles Index has been in existence for at least the past ten years. We did not initially include the performance for this benchmark in the table since the table shows performance through December 31, 2003, and the new benchmark will not take effect until December 1, 2004. However, to avoid confusion, we will include the Merrill Lynch benchmark's performance in our 485(b) filing, and it will appear in the printed prospectus. COMMENT 6: - PROSPECTUS - FEES AND EXPENSES COMMENT: You commented regarding the difference between the fund's expense ratio for fiscal year 2003 (0.84%), which is included in our Plain Talk About Expenses, compared to the estimated expense ratio for fiscal 2004 (0.71%), which is included in the Annual Fund Operating Expense table. You noted that we should explain the drop in expenses from 2003 to 2004. RESPONSE: We included the estimated expense ratio in the Annual Fund Operating Expense table since this prospectus includes six- month financials derived from the shareholder report. We will update the Plain Talk About Expenses to include this estimated expense ratio for 2004 rather than the actual 2003 expense ratio, so there will not be a discrepancy between the expense ratios in the table and the Plain Talk box. We do not plan to include text explaining the difference in expense ratio from 2003 to 2004 since it is solely attributable to an increase of over $200 million in the fund's asset base. COMMENT 7: - PROSPECTUS - MORE ON THE FUND COMMENT: IF THE FUND'S OBJECTIVE IS NON-FUNDAMENTAL, STATE THAT FACT IN THE PROSPECTUS. RESPONSE: The fund's objective is fundamental, so we will add the missing disclosure to the list of fundamental objectives in the SAI. COMMENT 8: - SAI - BOARD REVIEW OF INVESTMENT ADVISORY ARRANGEMENTS COMMENT: FLESH OUT THE DISCUSSION OF WHAT THE BOARD CONSIDERED IN REVIEWING THE ADVISORY ARRANGEMENTS FOR THE FUND. RESPONSE: We have expanded the discussion of the board's consideration of the fund's advisory arrangements. (See attached.) COMMENT 9: TANDY REQUIREMENTS COMMENT: The SEC is now requiring all registrants to provide at the end of response letters to registration statement comments, the following statements: o The Fund is responsible for the adequacy and accuracy of the disclosure in the filing. o Staff comments or changes in response to staff comments in the filings reviewed by the staff do not foreclose the Commission from taking any action with respect to the filing. o The Fund may not assert staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States. RESPONSE: AS REQUIRED BY THE SEC, WE WILL PROVIDE THE FOREGOING ACKNOWLEDGEMENTS. * * * * * AS REQUIRED BY THE SEC, THE FUND ACKNOWLEDGES THAT: o The Fund is responsible for the adequacy and accuracy of the disclosure in the filing. o Staff comments or changes in response to staff comments in the filings reviewed by the staff do not foreclose the Commission from taking any action with respect to the filing. o The Fund may not assert staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States. Please contact me at (610) 669-1538 with any questions or comments regarding the above responses or the accompanying attachment. Thank you. Sincerely, Judith L. Gaines Associate Counsel Attachment ATTACHMENT BOARD REVIEW OF INVESTMENT ADVISORY ARRANGEMENTS. The Fund's board of trustees oversees the Fund's management and performance on a regular basis, and the board determines annually whether to approve and renew the Fund's investment advisory agreement. Vanguard provides the board with monthly, quarterly, and annual analyses of the advisor's performance. In addition, the investment advisor provides the board with quarterly self-evaluations and certain other information the board deems important to evaluate the short- and long-term performance of the advisor. The Fund's portfolio managers meet with the board periodically to discuss the management and performance of the Fund. When considering whether to renew an investment advisory contract, the board examines several factors, but does not identify any particular factor as controlling their decision. Some of the factors considered by the board include: the nature, extent, and quality of the advisory services provided as well as other material facts, such as the investment performance of the Fund's assets managed by the advisor and the fair market value of the services provided. The board reviews and considers the extent to which the advisor has realized or will realize economies of scale as the Fund grows. Additional information is provided to the board detailing other sources of revenue to the advisor or its affiliates from its relationship with the Fund and intangible or "fall-out" benefits that accrue to the advisor and its affiliates, if relevant, and the advisor's control of the investment expenses of the Fund, such as transaction costs, including ways in which portfolio transactions for the Fund are conducted and brokers are selected. For Vanguard Convertible Securities Fund, the board also takes into account the nature of the fee arrangements, which include breakpoints that will adjust the fee downward as the size of the Fund increases and a performance adjustment that is designed to benefit shareholders by aligning the advisor's fee with the investment returns delivered to shareholders. The board also reviews the investment performance of the Fund compared with a peer group of funds and an appropriate index or combination of indexes, in addition to a comparative analysis of expense ratios of, and advisory fees paid by, similar funds. Credit Suisse First Boston is eliminating the Credit Suisse First Boston Convertible Securities Index, which was the benchmark index for the Fund. Accordingly, the Fund's board of trustees approved Merrill Lynch All US Convertibles Index, a similar index tracking U.S. corporate convertible securities, as the new benchmark index, effective December 1, 2004. In its most recent review of the Fund's advisory agreement, the board identified no single factor that controlled the decision. The primary factors underlying the board's determination to renew the fund's advisory arrangements were as follows: ADVISORY FEES AVERAGE ANNUAL RETURN (BEFORE TAXES) EXPRESSED AS AN ------------------------------------ ANNUAL EFFECTIVE 1 YEAR ENDED 5 YEARS ENDED 10 YEARS ENDED RATE OF THE FUNDS' 11/30/2003 11/30/2003 11/30/2003 EXPENSE RATIO AVERAGE NET ASSETS ----------- ------------ -------------- ------------- ------------------ VANGUARD CONVERTIBLE 28.07% 9.79% 8.71% 0.84% 0.38% SECURITIES FUND Average Convertible Securities Fund* 22.06 7.03 8.44 1.49 0.62 CS First Boston Convertible Securities Index** 23.66 8.28 9.12 N/A N/A Merrill Lynch All US Convertibles Index** 22.47 7.46 9.30 N/A N/A *Derived from data provided by Lipper Inc. **Credit Suisse First Boston is eliminating the CS First Boston Convertible Securities Index. The Fund's board of trustees approved Merrill Lynch All US Convertibles Index as the new benchmark, effective December 1, 2004. - - The board considered the Fund's short- and long-term performance records, which are disclosed in the table above. The board determined that the performance results for the Fund were reasonable, particularly over the long-term, as compared with relevant performance standards, including the performance results of the average peer group fund (derived from data provided by Lipper Inc.) and other appropriate benchmarks. - - The board assessed the advisory fee paid by the Fund and compared it to the average advisory fee for the Fund's Lipper peer group. The board took into account the nature of the fee arrangements, which include breakpoints that decrease the fee rate as the size of the advisor's portfolio increases. The board concluded that the advisory fee paid to Oaktree was reasonable and was significantly less that the average advisory fee paid by others in the Fund's Lipper peer group. - - The board evaluated the advisor's investment staff and portfolio management process, and reviewed the composition and overall performance of the advisor's portfolio on both a short-term and long-term basis. Following the review, the board noted the portfolio management team's outstanding experience and education. The board concluded that the advisor's investment staff and portfolio management process were solid and were suitable for the Fund. - - Finally, the board considered whether the Fund should obtain alternative portfolio management services and concluded that, under all the circumstances and based on its informed business judgment, the most appropriate course of action in the best interest of the Fund's shareholders was to renew the agreement with Oaktree.
