Amendment No. 26 is marked to show changes in response to the comments of the Commission's staff (the "Staff") on Amendment No. 25 that were provided by Christian T. Sandoe of the Staff in a telephone conversation with Albert Cho. For the convenience of the Staff, the substance of those comments has been set forth below. The Fund's responses to each comment is set out immediately under the restated comment. Page references in the Fund's responses are to the Fund's revised Class A and Class C Prospectus (the "Revised Prospectus") filed as part of Amendment No. 26. Please note that conforming changes have also been made to the Fund's Common Class Prospectus, which was initially filed as part of Amendment No. 25. Various other stylistic and clarifying changes have also been made in Amendment No. 26. PROSPECTUS: 1. KEY POINTS - OVERVIEW (P. 3): To the extent possible please reduce the amount of information in the "Overview" section of the prospectus by either incorporating that information into the Risk/Return Summary, to the extent possible, or moving it behind the Risk/Return Summary. Securities and Exchange Commission August 25, 2005 Page 2 Response: The "Overview" section has been revised as requested. 2. GOALS AND PRINCIPAL STRATEGIES - PRINCIPAL STRATEGIES (P. 4): Please provide additional information in the Risk/Return Summary to give investors a sense as to how much each Fund will invest within categories of underlying Credit Suisse Funds (e.g., money market, investment grade, high yield). Response: In order to address the Staff's comment without adding redundancies to the prospectus we have added disclosure referring investors to a chart on page 20 detailing approximately how much of each Fund will be invested in categories of underlying Credit Suisse Funds such as money market, investment grade, high yield, large and mid cap, small cap and international. 3. A WORD ABOUT RISK - PRINCIPAL RISKS (P. 6); RISK FACTORS (P. 31): Please include the principal risks of the underlying Credit Suisse Funds in the Risk/Return Summary and Risk Factors section of the prospectus. Response: We have made the requested change. 4. A WORD ABOUT RISK - CONFLICTS OF INTEREST RISKS (P. 5); RISK FACTORS (P. 31): Please consider whether "conflicts of interest risk" should be re-classified under "other risk factors." Response: We have re-classified "conflicts of interest risk" under "other risk factors." 5. INVESTOR EXPENSES - FEES AND FUND EXPENSES - FOOTNOTE 4 (P. 16): Please confirm whether the reference to "average daily net assets attributable to other investments" in the discussion of the management fee calculation means that the Funds intend to invest in other securities and other financial instruments in reliance on an exemptive order from the Commission. Response: As noted in the prospectus, the Funds intend to seek exemptive relief (i.e., page 30). The reference to "other investments" relates to the investments to be made by the Funds in reliance on such order, if obtained. 6. PORTFOLIO MANAGEMENT (P. 31); MEET THE MANAGERS (P. 39): Please provide the names and biographies of the portfolio managers and confirm that the reason why this information was not included in the initial filing was that it was unavailable at the time.
