(the "Fund") for use at a Special Meeting of Shareholders at the offices of Credit Suisse Asset Management, LLC ("CSAM" or the "Manager"), 466 Lexington Avenue (between 45th and 46th streets), 16th Floor, New York, New York 10017 on August 10, 2004 (commencing at 11:00 a.m. New York time) and at any adjournments thereof (collectively, the "Special Meeting" or the "Meeting"). A Notice of Special Meeting of Shareholders and a proxy card (the "Proxy") accompany this Proxy Statement. Proxy solicitations will be made primarily by mail, but solicitations may also be made by telephone, telegraph or personal interviews conducted by officers or employees of the Fund, CSAM, the investment adviser to the Fund, Brown Brothers Harriman & Co., the administrator of the Fund (the "Administrator"), or D.F. King & Co., Inc. ("D.F. King"), a proxy solicitation firm that has been retained by the Fund and which will receive a fee not to exceed $3,000 and will be reimbursed for its reasonable expenses. All costs of solicitation, including (a) printing and mailing of this Proxy Statement and accompanying material, (b) the reimbursement of brokerage firms and others for their expenses in forwarding solicitation material to the beneficial owners of the Fund's shares, (c) payment of D.F. King for its services in soliciting Proxies and (d) supplementary solicitations to submit Proxies, will be borne by CSAM. This Proxy Statement is expected to be mailed to shareholders on or about July 15, 2004. CSAM has its principal executive office at 466 Lexington Avenue, 16th Floor, New York, New York 10017. The Administrator has its principal executive office at 40 Water Street, Boston, Massachusetts 02109. The Fund's Annual Report containing audited financial statements for the fiscal year ended December 31, 2003 has been previously provided to shareholders. It is not to be regarded as proxy-soliciting material. THE FUND WILL FURNISH, WITHOUT CHARGE, A COPY OF ITS MOST RECENT ANNUAL REPORT AND ANY MORE RECENT SEMI-ANNUAL REPORT TO A SHAREHOLDER UPON REQUEST. ANY SUCH REQUEST SHOULD BE DIRECTED TO THE FUND BY CALLING 1-800-293-1232, BY WRITING TO CREDIT SUISSE ASSET MANAGEMENT INCOME FUND, INC. C/O CREDIT SUISSE ASSET MANAGEMENT, LLC AT 466 LEXINGTON AVENUE, 16TH FLOOR, NEW YORK, NEW YORK 10017, OR AT THE FUND'S WEBSITE AT http://www.CSAM.com/us. THESE REQUESTS WILL BE HONORED WITHIN THREE BUSINESS DAYS OF RECEIPT. If the enclosed Proxy is properly executed and returned in time to be voted at the Special Meeting, the shares represented thereby will be voted in accordance with the instructions marked on the Proxy. If no instructions are marked on the Proxy, the Proxy will be voted "FOR" the approval of the new investment sub-advisory agreement among the Fund, CSAM and Credit Suisse Asset Management Limited ("CSAM U.K." or the Sub-Adviser"). Any shareholder giving a Proxy has the right to attend the Special Meeting to vote his or her shares in person (thereby revoking any prior Proxy) and also the right to revoke the Proxy at any time by written notice received by the Fund prior to the time it is voted. 1 <Page> A quorum of shareholders is constituted by the presence in person or by proxy of the holders of a majority of the outstanding shares of the Fund entitled to vote at the Special Meeting. In the event that a quorum is not present at the Special Meeting, the holders of a majority of the shares present in person or by proxy will have the power to adjourn the Special Meeting, without notice other than an announcement at the Special Meeting, until the requisite number of shares entitled to vote at the Special Meeting is present. In the event that a quorum is present at the Special Meeting but sufficient votes to approve any of the proposals are not received, the persons named as proxies may propose one or more adjournments of the Special Meeting to permit further solicitation of Proxies. Any such adjournment will require the affirmative vote of a majority of the Fund's shares represented at the Special Meeting in person or by proxy, and the persons named as proxies will vote those Proxies that they are entitled to vote "FOR" any proposal in favor of such adjournment and will vote those proxies required to be voted "AGAINST" any proposal against any such adjournment. Absent the establishment of a subsequent record date and the giving of notice to the holders of record thereon, the adjourned Special Meeting must take place not more than 120 days after the record date. At such adjourned Special Meeting, any business may be transacted which might have been transacted at the original Special Meeting. If a quorum is present, a shareholder vote may be taken on one or more of the proposals properly brought before the Special Meeting prior to any adjournment if sufficient votes have been received and it is otherwise appropriate. For purposes of determining the presence of a quorum for transacting business at the Special Meeting, abstentions and broker "non-votes" (that is, proxies from brokers or nominees indicating that such persons have not received instructions from the beneficial owner or other persons entitled to vote shares on a particular matter with respect to which the brokers or nominees do not have discretionary power) will be treated as shares that are present but which have not been voted. Accordingly, shareholders are urged to forward their voting instructions promptly. CSAM is seeking shareholders' approval of a new investment sub-advisory agreement among the Fund, CSAM and CSAM U.K. If shareholders approve the proposal: -CSAM U.K. will manage the day-to-day investment of the portion of the Fund's assets allocated to CSAM U.K. by the Manager, consistent with the Fund's investment objectives, policies and strategies. -The advisory fees payable by the Fund will not change. -The new investment sub-advisory agreement will take effect on August 11, 2004. Approval of the investment sub-advisory agreement will require the affirmative vote of a majority of the outstanding voting securities of the Fund, which means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or (2) 67% or more of the shares of the Fund present at the Special Meeting if more than 50% of the Fund's outstanding shares are present at the Special Meeting in person or by proxy. Abstentions and broker non-votes will have the effect of votes "AGAINST" Proposal 1 for purposes of tabulating votes necessary for its approval. CSAM and its affiliates have advised the Fund that they intend to vote the shares over which they have voting power at the Special Meeting, including shares that are held directly or on behalf of employees, in the manner instructed by the customers or employees for which such shares are held. The Fund has one class of shares of capital stock, par value $0.001 per share (the "Shares"). On the record date, June 14, 2004, there were 49,895,588 Shares outstanding. Each Share is entitled to one vote at the Special Meeting, and fractional Shares are entitled to a proportionate share of one vote. In order that your Shares may be represented at the Special Meeting, you are requested to: -indicate your instructions on the Proxy; -date and sign the Proxy; -mail the Proxy promptly in the enclosed envelope; -allow sufficient time for the Proxy to be received and processed on or before 11:00 a.m. on August 10, 2004. 2 <Page> PROPOSAL 1 APPROVAL OF A NEW INVESTMENT SUB-ADVISORY AGREEMENT AMONG THE FUND, CSAM AND CSAM U.K. INTRODUCTION The Fund's shareholders will be asked at the Meeting to approve an Investment Sub-Advisory Agreement (the "Sub-Advisory Agreement") among the Fund, CSAM and CSAM's United Kingdom affiliate, CSAM U.K. The Sub-Advisory Agreement was unanimously approved by the Board, including all of the Directors (the "Directors") who are not parties to the Sub-Advisory Agreement or "interested persons" (as defined under the 1940 Act) of any such parties (the "Non-Interested Directors") at a meeting held on May 18, 2004. At the meeting, CSAM, as investment adviser to the Fund, recommended to the Board that the Fund retain CSAM U.K. as sub-investment adviser and that pursuant to the proposed Sub-Advisory Agreement, CSAM (and not the Fund) pay CSAM U.K. a sub-advisory fee of $250,000 per annum for services rendered with respect to the Fund and all other Credit Suisse Funds for which CSAM U.K. has been appointed to act as sub-adviser. Thus, the retention of CSAM U.K. will not increase the fees or expenses otherwise incurred by the Fund or its shareholders. Under the proposed Sub-Advisory Agreement, CSAM will monitor the activities and performance of CSAM U.K. The Sub-Advisory Agreement for the Fund as approved by the Board is now being submitted for approval by the Fund's shareholders. If approved by the Fund's shareholders, the Sub-Advisory Agreement will take effect on August 11, 2004 and will remain in effect for an initial two-year period. Thereafter, the Sub-Advisory Agreement will continue automatically for successive one-year periods, provided that it is approved at least annually by a vote of a majority of the Directors, including a majority of the Non-Interested Directors. If the shareholders of the Fund do not approve the Sub-Advisory Agreement, the Board will consider appropriate action with respect to such non-approval. Any description of the agreement set forth in this proxy statement is qualified in its entirety by the agreement, a form of which is attached to this proxy statement as Appendix A. CSAM U.K.'s principal office is located at Beaufort House, 15 St. Botolph Street, London, EC3A 7JJ. AS DESCRIBED ABOVE, THE SUB-ADVISORY FEE PAYABLE TO CSAM U.K. PURSUANT TO THE SUB-ADVISORY AGREEMENT WILL BE PAID BY CSAM AND, ACCORDINGLY, THE RETENTION OF CSAM U.K. WILL NOT INCREASE THE FEES OR EXPENSES OTHERWISE INCURRED BY THE FUND OR ITS SHAREHOLDERS. BOARD EVALUATION AND RECOMMENDATION In considering whether to approve the Sub-Advisory Agreement for CSAM U.K. and recommend approval to shareholders, the Board, including the Non-Interested Directors, considered various information and materials provided by CSAM and CSAM U.K. The Board considered, primarily, the benefits to the Fund of retaining CSAM U.K. given the increased complexity of the domestic and foreign securities markets, specifically that retention of CSAM U.K. would expand the universe of companies and countries from which investment opportunities can be sought and enhance the Fund's ability to obtain best price and execution on trades in foreign markets, including emerging markets. The Board also carefully considered the particular expertise of CSAM U.K. in managing the types of global investments which the Fund makes, including their personnel and research capabilities. The Board also evaluated the extent of the proposed services to be offered by the Sub-Adviser. The Board considered the Manager's belief that the sub-advisory fees payable to CSAM U.K. were within the range of fees charged by other investment advisers with respect to similar closed-end funds and were reasonable and fair 3 <Page> in relation to the advisory services provided. In addition, the Board took into account the lack of any anticipated adverse impact to the Fund as a result of the Sub-Advisory Agreement, particularly noting that THE COMPENSATION PAID TO CSAM U.K. WILL BE PAYABLE BY CSAM AND, ACCORDINGLY, THAT THE RETENTION OF CSAM U.K. WILL NOT INCREASE THE FEES OR EXPENSES OTHERWISE INCURRED BY THE FUND OR ITS SHAREHOLDERS AND THAT ALL COSTS OF THE SOLICITATION AND THE MEETING WILL BE BORNE BY CSAM. After considering the relevant factors, the Directors, including all of the Non-Interested Directors, unanimously approved the Sub-Advisory Agreement and recommended approval by shareholders of the Fund. BACKGROUND INFORMATION REGARDING THE FUND The Fund invests primarily in fixed-income securities. Currently, Brown Brothers Harriman & Co. ("Brown Brothers") serves as the Fund's administrator and custodian. Brown Brothers principal business address is 40 Water Street, Boston, Massachusetts 02109. THE ADMINISTRATION AND CUSTODIAN AGREEMENTS BETWEEN THE FUND AND BROWN BROTHERS WILL NOT BE AFFECTED BY THE PROPOSED SUB-ADVISORY AGREEMENT. DESCRIPTION OF CURRENT INVESTMENT ADVISORY AGREEMENT CSAM serves as investment adviser to the Fund pursuant to a written investment advisory agreement between CSAM and the Fund (the "Investment Advisory Agreement"). CSAM is the institutional and mutual fund asset management arm of Credit Suisse First Boston ("CSFB"), part of the Credit Suisse Group ("Credit Suisse"), one of the world's largest financial organizations with approximately $974 billion in assets under management as of March 31, 2004. CSFB is a leading global investment bank serving institutional, corporate, government and individual clients. CSFB's businesses include securities underwriting, sales and trading, investment banking, private equity, financial advisory services, investment research, venture capital, correspondent brokerage services and asset management. CSFB operates in 77 locations in 36 countries across six continents. CSFB is a business unit of the Zurich-based Credit Suisse Group, a leading global financial services company. As of March 31, 2004, Credit Suisse Asset Management employed approximately 1,962 people worldwide and had global assets under management of approximately $324.4 billion, with $48 billion in assets under management in the U.S. The principal business address of Credit Suisse Group is Paradeplatz 8, CH8070, Zurich, Switzerland. Pursuant to the Investment Advisory Agreement with CSAM, subject to the supervision and direction of the Board, CSAM is responsible for managing the Fund in accordance with the Fund's stated investment objective and policies. CSAM is responsible for providing investment advisory services as well as conducting a continual program of investment, evaluation and, if appropriate, sale and reinvestment of the Fund's assets. In addition to expenses that CSAM may incur in performing its services under the Investment Advisory Agreement, CSAM pays the compensation, fees and related expenses of all Directors who are employed by CSAM or any of its subsidiaries and, if the Sub-Advisory Agreement is approved by the shareholders of the Fund, will pay the sub-advisory fee to CSAM U.K. as described more fully below. The Fund pays all other expenses incurred in its operations, including general administrative expenses. The Investment Advisory Agreement dated May 14, 2001 was last approved by shareholders on May 1, 2001 in connection with the reorganization of Credit Suisse Asset Management Strategic Global Income Fund, Inc. into the Fund. As compensation for its services to the Fund, CSAM receives compensation at an annual rate of 0.50% of the lesser of (i) the market value of the Fund's outstanding shares or (ii) the Fund's net assets, in each case determined 4 <Page> as of the last trading day for each week during that quarter. For the fiscal year ended December 31, 2003, CSAM received $1,038,753 in total compensation from the Fund. REGARDLESS OF WHETHER THE SUB-ADVISORY AGREEMENT IS APPROVED, CSAM WILL CONTINUE TO SERVE AS INVESTMENT ADVISER TO THE FUND PURSUANT TO THE ADVISORY AGREEMENT AND BROWN BROTHERS WILL CONTINUE TO PROVIDE ADMINISTRATIVE SERVICES TO THE FUND. DESCRIPTION OF PROPOSED SUB-ADVISORY AGREEMENT Subject to the supervision of CSAM, the Sub-Advisory Agreement requires CSAM U.K., in the exercise of its best judgment, to provide investment advisory assistance and portfolio management advice to the Fund in accordance with the Fund's Articles of Incorporation, as may be amended from time to time, and the Fund's Registration Statement, as from time to time in effect, and in such manner and to such extent as may from time to time be approved by the Board. In connection with the Sub-Advisory Agreement, CSAM U.K. will, subject to the supervision and direction of CSAM: (1) manage that portion of the Fund's assets allocated to CSAM U.K. by the Manager from time to time (the "Assets") or furnish recommendations to manage the Assets in accordance with the Fund's investment objective and policies; (2) make investment decisions or recommendations with respect to the Assets; (3) if requested by CSAM, place purchase and sale orders for securities on behalf of the Fund with respect to the Assets; (4) exercise voting rights with respect to the Assets if requested by CSAM; and (5) furnish CSAM and the Fund's Board with such periodic and special reports as the Fund or CSAM may reasonably request. In connection with the performance of services under the Sub-Advisory Agreement, CSAM U.K. may contract at its own expense with third parties for the acquisition of research, clerical services and other administrative services that would not require such third parties to be required to register as an investment adviser under the Investment Advisers Act of 1940, as amended (the "Advisers Act"); provided that CSAM U.K. remains liable for the performance of each such third party's duties. The services of CSAM U.K. under the proposed Sub-Advisory Agreement are not exclusive. CSAM U.K. has the right to provide similar services to other investment companies or to engage in other activities, provided that those activities do not adversely affect its ability to perform its services under the Sub-Advisory Agreement. The Sub-Advisory Agreement will terminate automatically in the event of its assignment. In addition, it may be terminated by CSAM or CSAM U.K. upon 60 days' written notice to the other parties; or with respect to the Fund, upon the vote of a majority of the Board or a majority of the outstanding voting securities of the Fund, upon 60 days' written notice to CSAM and CSAM U.K. In consideration of the services rendered pursuant to a Sub-Advisory Agreement, CSAM will pay CSAM U.K. an aggregate fee of $250,000 per annum (the "Total Fee"). The Total Fee shall be an aggregate fee paid for services rendered with respect to all Credit Suisse Funds for which CSAM U.K. has been appointed as sub-adviser and which CSAM and CSAM U.K. agree will be governed by this fee schedule. CSAM U.K. currently serves as sub-adviser to ten other Credit Suisse Funds which are all governed by this fee schedule. The Total Fee may be amended from time to time upon the mutual agreement of the parties upon notice to shareholders. Twenty-five percent of the Total Fee shall be payable in U.S. dollars in arrears on the last day of each calendar quarter. The fee 5 <Page> for the first period during which a Sub-Advisory Agreement is in effect shall be pro-rated for the portion of the calendar quarter that the Sub-Advisory Agreement is in effect. The portion of the Total Fee allocable with respect to the Fund (for any calendar quarter or portion thereof) is equal to the product of (a) the Total Fee and (b) a fraction: (i) the numerator of which is the average monthly net assets of the Fund during such calendar quarter or portion thereof, and (ii) the denominator of which is the sum of the total average monthly net assets of the Fund and other registered investment companies for which CSAM U.K. has been appointed as sub-adviser during such calendar quarter or portion thereof. Based upon this formula, the portion of the Total Fee allocable to the Fund for the calendar quarter ended June 30, 2004 would have been $9,909. CSAM WILL PAY CSAM U.K. THE SUB-ADVISORY FEE. CSAM U.K. DOES NOT HAVE A RIGHT TO OBTAIN COMPENSATION DIRECTLY FROM THE FUND FOR SERVICES PROVIDED UNDER THE SUB-ADVISORY AGREEMENT AND MUST LOOK SOLELY TO CSAM FOR PAYMENT OF FEES DUE.

In connection therewith, the Sub-Adviser will: (i) manage the Assets or furnish recommendations to manage the Assets in accordance with the Fund's investment objective and policies; (ii) make investment decisions or recommendations with respect to the Assets; (iii) if requested by CSAM, place purchase and sale orders for securities on behalf of the Fund with respect to the Assets; (iv) exercise voting rights with respect to the Assets if requested by CSAM; and A-1 <Page> (v) furnish CSAM and the Fund's Board of Directors with such periodic and special reports as the Fund or CSAM may reasonably request. In providing those services, the Sub-Adviser will, if requested by CSAM, provide investment research and supervision of the Assets and conduct a continual program of investment, evaluation and, if appropriate, sale and reinvestment of the Assets. 2.2 In connection with the performance of the services of the Sub-Adviser provided for herein, the Sub-Adviser may contract at its own expense with third parties for the acquisition of research, clerical services and other administrative services that would not require such parties to be required to register as an investment adviser under the Advisers Act; provided that the Sub-Adviser shall remain liable for the performance of its duties hereunder. 3. EXECUTION OF TRANSACTIONS 3.1 In executing transactions for the Assets, selecting brokers or dealers and negotiating any brokerage commission rates, the Sub-Adviser will use its best efforts to seek the best overall terms available. In assessing the best overall terms available for any portfolio transaction, the Sub-Adviser will consider all factors it deems relevant including, but not limited to, the breadth of the market in the security, the price of the security, the financial condition and execution capability of the broker or dealer and the reasonableness of any commission for the specific transaction and for transactions executed through the broker or dealer in the aggregate. In selecting brokers or dealers to execute a particular transaction and in evaluating the best overall terms available, to the extent that the execution and price offered by more than one broker or dealer are comparable the Sub-Adviser may consider any brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934) provided to the Sub-Adviser or to CSAM for use on behalf of the Fund or other clients of the Sub-Adviser or CSAM. 3.2 It is understood that the services of the Sub-Adviser are not exclusive, and nothing in this Agreement shall prevent the Sub-Adviser from providing similar services to other investment companies or from engaging in other activities, provided that those activities do not adversely affect the ability of the Sub-Adviser to perform its services under this Agreement. The Fund and CSAM further understand and acknowledge that the persons employed by the Sub-Adviser to assist in the performance of its duties under this Agreement will not devote their full time to that service. Nothing contained in this Agreement will be deemed to limit or restrict the right of the Sub-Adviser or any affiliate of the Sub-Adviser to engage in and devote time and attention to other businesses or to render services of whatever kind or nature, provided that doing so does not adversely affect the ability of the Sub-Adviser to perform its services under this Agreement. 3.3 On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Fund as well as of other investment advisory clients of the Sub-Adviser, the Sub-Adviser may, to the extent permitted by applicable laws and regulations, but shall not be obligated to, aggregate the securities to be so sold or purchased with those of its other clients. In such event, allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by the Sub-Adviser in a manner that is fair and equitable, in the judgment of the Sub-Adviser, in the exercise of its fiduciary obligations to the Fund and to such other clients. The Sub-Adviser shall provide to CSAM and the Fund all information reasonably requested by CSAM and the Fund relating to the decisions made by the Sub-Adviser regarding allocation of securities purchased or sold, as well as the expenses incurred in a transaction, among the Fund and the Sub-Adviser's other investment advisory clients. 3.4 In connection with the purchase and sale of securities for the Fund, the Sub-Adviser will provide such information as may be reasonably necessary to enable the custodian and co-administrators to perform their administrative and recordkeeping responsibilities with respect to the Fund.

UNITED KINGDOM REGULATORY MATTERS The Sub-Adviser is regulated by the Financial Services Authority ("FSA") in carrying out its investment business.

Under the FSA Rules, the following provisions apply: (a) The FSA requires that all clients of the Sub-Adviser be classified into specific categories. On the basis of the information which CSAM has given, the Sub-Adviser has determined that CSAM is an Intermediate Customer and the Fund is a Private Customer. (b) (i) The Sub-Adviser is permitted to trade in Futures, Options and Contracts for Differences including on and off exchange transactions ("Derivative Instruments"), subject to limitations described herein. The markets on which Derivative Instruments are executed can be highly volatile. Such investments carry a high risk of loss and a relatively small adverse market movement may result not only in the loss of the original investment but also in unquantifiable further loss exceeding any margin deposited. (ii) The Sub-Adviser may instruct the Custodian to pay margin, or (subject to the rules of the exchange concerned) deposit investments by way of margin or collateral, on any Derivative Instrument out of the Assets. The Fund shall not be required to pay margin in cash beyond the amount of cash held at the relevant time on the Fund's behalf and immediately available for margin payments. (c) The Sub-Adviser will not supply the Fund with contract notes. The periodic reports provided under Section 2.1(v) will contain information that would have been provided in the contract notes. (d) In order to comply with applicable laws and related regulatory requirements, there may be periods when the Sub-Adviser will not be permitted to initiate or recommend certain types of transactions. A-7 <Page> (e) No warranty is given by the Sub-Adviser as to the performance or profitability of the Assets or any part of them. (f) The Sub-Adviser has in operation a written procedure in accordance with the FSA Rules for the effective consideration and proper handling of complaints from customers. Any complaint by CSAM or the Fund hereunder should be sent in writing to the Compliance Officer of the Sub-Adviser at the address specified in Section 14. ****************** A-8 <Page> Please confirm that the foregoing is in accordance with your understanding by indicating your acceptance hereof at the place below indicated, whereupon it shall become a binding agreement between us.
