We sent you this Proxy Statement and the enclosed proxy card because Ambac's Board of Directors is soliciting your proxy to vote at the 2002 Annual Meeting of Stockholders. This Proxy Statement summarizes the information you need to vote at the Annual Meeting. You do not need to attend the Annual Meeting to vote your shares. You may simply complete, sign and return the enclosed proxy card or vote by telephone or over the Internet. WHO IS ENTITLED TO VOTE? If you owned Ambac common stock at the close of business on March 18, 2002, you are entitled to vote. On that date, there were 105,909,028 shares of Ambac common stock outstanding. Ambac common stock is our only class of voting stock. We will begin mailing this Proxy Statement on March 28, 2002 to all stockholders entitled to vote. HOW MANY VOTES DO I HAVE? You have one vote for each share of Ambac common stock that you owned at the close of business on March 18, 2002. The proxy card indicates the number. HOW DO I VOTE BY PROXY? If you properly fill in your proxy card and send it to us in time to vote, your "proxy" (one of the individuals named on your proxy card) will vote your shares as you have directed. If you sign the proxy card but do not make specific choices, your proxy will vote your shares as recommended by the Board: . "FOR" Proposal 1 (Elect Seven Directors); and . "FOR" Proposal 2 (Ratify Selection of KPMG LLP as Independent Auditors for 2002). If any other matter is presented, your proxy will vote in accordance with his or her best judgment. At the time we began printing this Proxy Statement, we knew of no matters that needed to be acted on at the Annual Meeting, other than those discussed in this Proxy Statement. MAY I VOTE BY TELEPHONE OR VIA THE INTERNET? Yes. Instead of submitting your vote by mail on the enclosed proxy card, you may be able to vote via the Internet or by telephone. Please note that there are separate Internet and telephone arrangements depending on whether you are a registered stockholder (that is, if you hold your stock in your own name), or whether you hold your shares in "street name" (that is, if your stock is held in the name of your broker or bank). If you are a registered stockholder, you may vote by telephone, or electronically through the Internet, by following the instructions provided on your proxy card. If your shares are held in "street name", you may need to contact your bank or broker to determine whether you will be able to vote by telephone or electronically. The telephone and Internet voting procedures are designed to authenticate stockholders' identities, to allow stockholders to give their voting instructions and to confirm that stockholders' instructions have been recorded properly. If you vote via the Internet, you may incur costs, such as usage charges from Internet access providers and telephone companies. You will be responsible for those costs. Whether you plan to attend the Annual Meeting or not, we urge you to vote. Returning the proxy card or voting by telephone or over the Internet will not affect your right to attend the Annual Meeting and vote. MAY I REVOKE MY PROXY? Yes. You may change your mind after you send in your proxy card by following any of these procedures. To revoke your proxy: . Send in another signed proxy with a later date; or . Send a letter revoking your proxy to Ambac's Corporate Secretary at the address indicated on page 31 under "Information about Stockholder Proposals"; or . Attend the Annual Meeting and vote in person. HOW DO I VOTE IN PERSON? If you plan to attend the Annual Meeting and vote in person, we will give you a ballot when you arrive. If your shares are held in the name of your broker, bank or other nominee, you must bring an account statement or letter from the nominee. The account statement or letter must show that you were the direct or indirect (beneficial) owner of the shares on March 18, 2002. 2 HOW DO EMPLOYEES IN THE AMBAC STOCK FUND VOTE? If you are an employee who participates in our Savings Incentive Plan ("SIP"), you are receiving this material because of shares held for you in the Ambac Stock Fund in the SIP. The SIP Trustee will send you a voting instruction card instead of a proxy card. This voting instruction card will indicate the number of shares of Ambac common stock credited to your account in the Ambac Stock Fund as of March 18, 2002. . If you complete, sign and return the voting instruction card on time, the SIP Trustee will vote the shares as you have directed. . If you do not complete, sign and return the voting instruction card on time, the SIP Trustee will not vote the shares credited to your account. WHAT VOTES DO WE NEED TO BE PRESENT TO HOLD THE ANNUAL MEETING? We need a majority of the shares of Ambac common stock outstanding on March 18, 2002 to be present, in person or by proxy, to hold the Annual Meeting. WHAT VOTE IS REQUIRED TO APPROVE EACH PROPOSAL? PROPOSAL 1: ELECT The seven nominees for director who receive the most SEVEN DIRECTORS votes will be elected. If you do not vote for a nominee, or you indicate "withhold authority to vote" for any nominee on your proxy card, your vote will not count either for or against the nominee. PROPOSAL 2: RATIFY The affirmative vote of a majority of the votes present SELECTION OF and entitled to vote at the Annual Meeting is required AUDITORS to ratify the selection of independent auditors. So, if you "abstain" from voting, it has the same effect as if you voted "against" this proposal. WHAT IS THE EFFECT OF BROKER NON-VOTES? Under the rules of the New York Stock Exchange, if your broker holds your shares in its "street" name, the broker may vote your shares on both proposals even if it does not receive instructions from you. However, if your broker does not vote on either of the proposals, it will have no effect on the outcome of the proposal. 3 IS VOTING CONFIDENTIAL? We maintain a policy of keeping all the proxies, ballots and voting tabulations confidential. The Inspectors of Election will forward to management any written comments that you make on the proxy card. WHAT ARE THE COSTS OF SOLICITING THESE PROXIES? Ambac will pay all the costs of soliciting these proxies. Although we are mailing these proxy materials, our directors and employees may also solicit proxies by telephone, by fax or other electronic means of communication, or in person. We will reimburse banks, brokers, nominees and other fiduciaries for the expenses they incur in forwarding the proxy materials to you. Georgeson Shareholder Communications, Inc. is assisting us with the solicitation of proxies for a fee of $8,500 plus out-of-pocket expenses. HOW DO I OBTAIN AN ANNUAL REPORT ON FORM 10-K?

Section 16(a) of the Securities Exchange Act of 1934 requires that our insiders--our directors, executive officers, and greater-than-10% stockholders--file reports with the SEC and the New York Stock Exchange on their initial beneficial ownership of Ambac common stock and any subsequent changes. They must also provide us with copies of the reports. We reviewed copies of all reports furnished to us and obtained written representations that no other reports were required. Based on this, we believe that all of our insiders complied with their filing requirements for 2001, except that, due to administrative error, one stock option exercise and the related exempt sale of stock sold to pay taxes and the exercise price was not timely reported by Mr. Lassiter. 7 INFORMATION ABOUT DIRECTORS THE BOARD OF DIRECTORS The Board of Directors oversees the business of Ambac and monitors the performance of management. In accordance with corporate governance principles, the Board does not involve itself in day-to-day operations. The directors keep themselves informed by discussing matters with the Chairman, other key executives and our principal external advisers (legal counsel, outside auditors, investment bankers and other consultants) by reading the reports and other materials that we send them regularly and by participating in Board and committee meetings. Ambac's Board usually meets five times per year in regularly scheduled meetings, but will meet more often if necessary. The Board met five times during 2001. All directors attended at least 75% of the Board meetings and meetings of the Committees of which they were members. Each of our directors also serves as a director of our principal operating subsidiary, Ambac Assurance Corporation, a leading triple-A rated financial guarantee insurance company. THE COMMITTEES OF THE BOARD The Board has three standing committees: the Audit Committee, the Compensation and Organization Committee and the Nominating Committee. None of the directors who serve as members of these committees is, or has ever been, an employee of Ambac or our subsidiaries. THE AUDIT COMMITTEE The Audit Committee recommends the selection of the independent auditors to the Board, approves the scope of the annual audit by the independent auditors and our internal auditors, reviews audit findings and accounting policies, assesses the adequacy of internal controls and risk management, reviews and approves Ambac's financial disclosures and oversees compliance with Ambac's Code of Business Conduct. The Committee also meets privately, outside the presence of Ambac management, with both the independent auditors and the internal auditors. Under the rules of the New York Stock Exchange, all of the members of the Audit Committee are independent. The Committee's Report for 2001 is printed below at page 11. In December 2001, the Board approved a revised Audit Committee Charter, which is attached to this Proxy Statement as Appendix A. The Committee met three times during 2001. Messrs. Callen, Dulude and Gregory and Dr. Caporali and Ms. Considine currently serve as members of the Committee. Mr. Callen serves as Chairman of the Committee. 8 THE COMPENSATION The Compensation and Organization Committee establishes AND ORGANIZATION and approves all elements of compensation for the COMMITTEE executive officers. Each year, as the SEC requires, the Committee reports to you on executive compensation. The Committee's Report on Executive Compensation for 2001 is printed below, starting at page 22. The Committee administers Ambac's 1997 equity plan and has sole authority for awards under the plan. The Committee evaluates existing and proposed employee benefit plans and may approve of plan changes. The Committee also administers the 1997 Executive Incentive Plan and Ambac's Deferred Compensation Plan for Outside Directors and Ambac's Senior Officer Deferred Compensation Sub-Plan of the 1997 Equity Plan. The Committee met three times during 2001. Messrs. Callen, Dulude and Gregory and Dr. Caporali and Ms. Considine currently serve as members of the Committee. Mr. Dulude serves as Chairman of the Committee. THE NOMINATING The Nominating Committee is responsible for identifying COMMITTEE and recommending qualified candidates to the Board for election as directors. In addition, our By-laws provide a procedure for you to recommend candidates for director at an annual meeting. For more information, see below at page 31 under "Information About Stockholder Proposals." The Committee did not meet during 2001. Messrs. Callen, Dulude and Gregory currently serve as members of the Committee. Mr. Gregory serves as Chairman of the Committee. HOW WE COMPENSATE DIRECTORS ANNUAL CASH FEE We compensate directors who are not employees of Ambac or our subsidiaries with an annual cash fee of $20,000 per year. ANNUAL We also grant each non-employee director 3,750 stock STOCK OPTION AWARD options on the date of each annual meeting. These options have an exercise price equal to the average of the high and low trading price of our stock on the New York Stock Exchange on the date of grant. The options generally will vest on the first anniversary of the date of the grant and expire on the date of the annual meeting held in the seventh calendar year following the date of the grant. AWARD OF Ambac grants each non-employee director 3,000 RESTRICTED STOCK restricted stock units ("RSUS") at the annual meeting UNITS EVERY at which the director is first elected to the Board. FIVE YEARS . These RSUs generally will vest on the date of the annual meeting held in the fifth year following the date of grant and will be settled by the delivery of one share of Ambac common stock for each RSU. 9 . If the director remains on the Board after the first award of RSUs vests, Ambac will grant the director a second award of 3,000 RSUs, subject to similar vesting conditions and restrictions on transfer. MEETING FEES We also pay each non-employee director a meeting fee of: . $1,000 for attendance at each meeting of stockholders and each Board meeting; and . $1,000 for attendance at each committee meeting. FEE FOR CHAIRING We pay an annual fee of $1,500 to each non-employee A COMMITTEE director who chairs a committee. EXPENSES AND Ambac reimburses all directors for travel and other BENEFITS related expenses incurred in attending stockholder, Board and committee meetings. We provide non-employee directors with life and health insurance benefits. We also allow them to participate in our Matching Gift Program up to $20,000. Under this Program, Ambac will match gifts by directors to qualified organizations. THE DEFERRED Under our Deferred Compensation Plan for Outside COMPENSATION Directors, non-employee directors may elect to defer PLAN all or part of their director compensation that is paid in cash. . At the director's election, we credit deferrals to a bookkeeping account that we maintain on the director's behalf either as a cash credit (which we credit with interest quarterly), or as phantom stock units ("PSU") based on the market value of Ambac common stock (on which we pay quarterly dividend equivalents in additional PSUs) or as performance units measured by the performance of those mutual funds the director selects out of a limited group of funds. . We do not fund the Deferred Compensation Plan. We settle accounts only in cash. SERVICE ON THE Although Ambac Assurance does not pay its non-employee AMBAC ASSURANCE directors an annual fee for serving on its Board of BOARD Directors, it does pay them meeting fees (in the same amounts as we do for the Ambac Board) and reimburses all directors for expenses. DIRECTORS We do not compensate our employees or employees of our WHO ARE subsidiaries for service as a director. We do, however, AMBAC reimburse them for travel and other related expenses. EMPLOYEES 10 THE AUDIT COMMITTEE REPORT The Audit Committee of Ambac is responsible for providing independent, objective oversight of Ambac's accounting functions and internal controls. The Audit Committee recommends the selection of the independent auditors to the Board. The Audit Committee is currently composed of five independent directors, each of whom is independent as defined under the rules of the New York Stock Exchange. The Audit Committee operates under a written charter adopted by the Board of Directors, attached to this Proxy Statement as Appendix A. Management is responsible for Ambac's internal controls and financial reporting process. The independent auditors are responsible for performing an independent audit of Ambac's consolidated financial statements in accordance with auditing standards generally accepted in the United States of America and to issue a report thereon. The Audit Committee's responsibility is to monitor and oversee these processes. However, none of the members of the Committee is professionally engaged in the practice of accounting or auditing nor are all of our members experts in those fields. The Committee relies without independent verification on the information provided to it and on the representations made by management and the independent auditors. In connection with these responsibilities, we met with management and KPMG LLP to review and discuss the December 31, 2001 financial statements. We also discussed with the independent accountants the matters required by Statement on Auditing Standards No. 61 (Communication with Audit Committees). The Corporation's independent accountants also provided us the written disclosures required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and we discussed with KPMG LLP its independence. Based upon the review and discussions referred to above, we recommended to the Board of Directors, and the Board of Directors has approved, that Ambac's audited financial statements be included in Ambac's Annual Report on SEC Form 10-K for the fiscal year December 31, 2001. We also recommended the selection of KPMG LLP as Ambac's independent auditors for 2002 and, based on that recommendation, the Board has selected KPMG LLP as Ambac's independent auditors for 2002. PRINCIPAL ACCOUNTING FIRM FEES Fees paid to KPMG LLP for the fiscal year ended December 31, 2001 were: Audit: $752,000; Financial Information Systems Design and Implementation Fees: $0 and All Other Fees: $428,000. Of the $428,000 All Other Fees, $206,500 were fees paid to KPMG LLP for consents and comfort letters provided by KPMG LLP in connection with the registration of securities of our clients which were guaranteed by Ambac Assurance. These fees were reimbursed to Ambac by the clients. THE AUDIT COMMITTEE Michael A. Callen, Chairman Renso L. Caporali March 22, 2002 Jill M. Considine Richard Dulude W.

For 2001, the Compensation and Organization Committee paid 25% of Messrs. Lassiter, Genader, Bivona and Boyle's bonus in RSUs. Amounts shown in this column are based on the market value of the underlying Common Stock on the date of grant and do not reflect the discount attributed to such value by the Committee to take account of vesting requirements, restrictions on transfer and other limitations. See page 25 for more detailed descriptions of these awards made pursuant to the Sub-Plan. As dividends are paid on the common stock, dividend equivalents are accrued on the RSUs as additional RSUs and vest according to the same schedule. (2)The number of securities underlying options for 1999, 2000 and 2001 includes restoration options awarded upon the exercise of stock options in accordance with Ambac's Restoration Option Program. For the specific breakdown of option and restoration option grants made in 2001, please refer below to the table on page 15 under "Option Grants in 2001." For a more detailed description of our Restoration Option Program, please see footnote 2 under the "Option Grants in 2001" table on page 15. 14 (3)The column called "ALL OTHER COMPENSATION" includes the amounts that Ambac contributed or credited on behalf of the named officers in 2001 to (a) our Savings Incentive Plan (the "SIP "), and (b) our Non-Qualified SIP. We credit amounts that we are precluded from contributing to the SIP because of limitations under the Internal Revenue Code to accounts that we maintain under Ambac's Non-Qualified SIP.

Each executive officer's options will vest in two equal installments when the market price of Ambac common stock meets or exceeds $64.00 and $78.00 for twenty consecutive trading days or no later than the sixth anniversary of the grant date. Vesting is accelerated upon retirement, death or permanent disability. Generally, all of the executive officers' options will expire seven years from the date of grant or, earlier, if employment terminates. (2)Restoration options were awarded upon the exercise of stock options in accordance with Ambac's Restoration Option Program. A restoration option is awarded automatically when the underlying option is exercised by tendering shares of common stock to pay the exercise price. Each restoration option will vest one year from the date of grant and has the same exercise, transfer and expiration provisions as its underlying option. (3)The exercise price per share is the fair market value of the common stock on the date of grant. We determine this by calculating the average of the high and low price of Ambac common stock on the New York Stock Exchange on the date of grant. (4)We calculated these values by using the Black-Scholes stock option pricing model as follows: FOR THE JANUARY OPTION GRANTS. The model, as we applied, uses the grant date of January 22, 2001. The fair market value on that date was $48.66 per share as we discussed above. The model also assumes: (a) a risk-free rate of return of 4.88% (which was the yield on a U.S. Treasury Strip zero coupon bond with a maturity that approximates the term of the option); (b) stock price volatility of 32.50%; (c) a constant dividend yield of 0.66% based on the quarterly cash dividend rate at the time of grant on Ambac common stock; and (d) an exercise date, on average, of 5.5 years after grant. 15 FOR THE RESTORATION OPTION GRANTS. We use the following assumptions in applying the model for each Restoration Option Grant: (a) a risk-free rate of return equal to the yield on grant date of a U.S. Treasury Strip zero coupon bond with a maturity that approximates the term of the option; (b) stock price volatility of Ambac common stock calculated using month-end closing prices of Ambac common stock on the New York Stock Exchange for the three year period prior to the grant date; (c) a constant dividend yield based on the quarterly cash dividend rate at the time of grant on Ambac common stock; and (d) exercise of the restoration option at the end of its term. WE DID NOT ADJUST THE MODEL FOR NON-TRANSFERABILITY, RISK OF FORFEITURE, OR VESTING RESTRICTIONS. THE ACTUAL VALUE (IF ANY) AN EXECUTIVE OFFICER RECEIVES FROM A STOCK OPTION WILL DEPEND UPON THE AMOUNT BY WHICH THE MARKET PRICE OF AMBAC COMMON STOCK EXCEEDS THE EXERCISE PRICE OF THE OPTION ON THE DATE OF EXERCISE. THE HYPOTHETICAL VALUES ARE PRESENTED PURSUANT TO SEC RULES AND THERE CAN BE NO ASSURANCE THAT THE AMOUNT STATED AS "GRANT DATE PRESENT VALUE" WILL ACTUALLY BE REALIZED.

"In-the-money" stock options are options for which the exercise price is less than the market price of the underlying stock on a particular date. THE PENSION PLAN Ambac's Pension Plan is a defined benefit pension plan intended to be tax-qualified under Section 401(a) of the Internal Revenue Code. . In general, officers and employees of Ambac and its subsidiaries become participants in the Pension Plan after one year of service. All executive officers participate in the Pension Plan. Non-employee directors of Ambac and our subsidiaries are not eligible to participate in the Pension Plan. . Benefits under the Pension Plan vest after five years. Upon normal retirement at age 65, a retired employee receives an annual pension from the Pension Plan, subject to a statutory limit. The Pension Plan also contains provisions for early retirement and survivor benefits. 16 The table below illustrates the annual pension benefits payable to executive officers under the Pension Plan. The table also reflects the excess and supplemental benefit plans that we have established to provide retirement benefits over Internal Revenue Code limitations. We calculated the benefits before offsetting (a) an employee's primary Social Security benefit and (b) benefits payable under the retirement plan of Citibank, N.A., Ambac's former parent company (the "CITIBANK PLAN"). Benefits shown in the table reflect a straight life form of annuity benefit. If payment is made in the form of a joint and survivor annuity, the annual amounts of benefit could be substantially below those illustrated.

"Average Compensation" is defined, generally, as average annual base salary (which, in the case of executive officers identified in the Summary Compensation Table on page 14, is the amount shown under the column called "SALARY") for the five highest consecutive paid years of the ten years of employment preceding retirement. SERVICE BEFORE 1992 For service prior to January 1, 1992, the annual retirement benefit is equal to 2% (with an offset for Social Security benefits) of an employee's Average Compensation (determined as if the employee retired on December 31, 1991) multiplied by years of credited service up to thirty years. 17 YEARS OF SERVICE In view of the change in the formula for determining benefits under the Pension Plan that became effective as of January 1, 1992 (the "TRANSITION DATE"), we prepared the above table to show the benefits payable depending on how many years of service the executive officer would have: . prior to the Transition Date, and . at Retirement. In order to simplify the chart, we show only 0, 15 and 30 years of service at Transition, since those values cover the range for our executive officers. The years of credited service under the Pension Plan (including credit for years of past service under the Citibank Plan) as of December 31, 2001 for executive officers named in the Summary Compensation Table were as follows: Mr. Lassiter--32 years, Mr. Genader--27 years, Mr. Bivona--24 years, Mr. Boyle--5 years, and Mr. Doyle--10 years. Under the terms of a special pension arrangement for Mr. Boyle, as of March 31, 2002, he will be credited with an additional five years of service. The benefits payable under the Pension Plan to employees who receive credit for years of past service under the Citibank Plan will be reduced by the amount of any benefits payable under the Citibank Plan. EMPLOYMENT AGREEMENT WITH THE CHIEF EXECUTIVE OFFICER IN GENERAL Ambac's employment agreement with Mr. Lassiter provides that he shall serve as the Chairman and Chief Executive Officer and as a director. . The agreement has a two year term, which is extended on a daily basis, until Ambac or Mr. Lassiter terminates it. . Mr. Lassiter is to receive a base salary at a rate not less than his current rate. . He is to participate in bonus arrangements under which he is eligible to earn an annual bonus based on Ambac's achieving certain performance goals to be established by the Board. Mr. Lassiter has a supplemental pension benefit that SUPPLEMENTAL PENSION will be based on the benefit formula of the Pension BENEFIT Plan that was in effect until the end of 1991. The formula, however, will take into account his bonus compensation (including that portion of his bonus paid in RSUs) and will be determined without giving effect to provisions of the Internal Revenue Code that limit the amount of compensation that may be taken into account in calculating benefits and the amount of annual benefits that may be paid. Mr. Lassiter's supplemental pension benefit will be reduced, however, to take account of enhancements in Ambac's contributions to the Savings Incentive Plan ("SIP") that we introduced in 1992. 18 PAYMENTS If Mr. Lassiter's employment is terminated other than AND BENEFITS for "Cause" (as we define it below), or if he resigns for "Good Reason" (as we define it below), Mr. Lassiter will: - -- AFTER . receive, for the remainder of the term (which TERMINATION OR typically would be for two years), compensation at RESIGNATION an annualized rate equal to the sum of his base annual salary and target bonus at the time of termination; . be fully vested in all awards under the 1991 Stock Incentive Plan and the 1997 Equity Plan; . receive a lump-sum payment equal to the amount that we would have contributed to his account under the SIP and any nonqualified plan we maintained during the two years following termination; . be credited with an additional two years of service under the Pension Plan; and . continue to participate in all Ambac medical and other welfare plans for a limited time following termination. - -- AFTER CHANGE IN All stock options and other awards under the 1997 CONTROL Equity Plan that are made to Mr. Lassiter after January 1, 1998 will vest in full upon the occurrence of a "Change in Control" (as we define it below), whether or not his employment is subsequently terminated. In addition, if Mr. Lassiter's employment terminates following a Change in Control, his severance amount would be calculated and paid in the same manner as we describe below under "Management Retention Agreements with Executive Officers." Mr. Lassiter would also be entitled to the "gross up" payment described in that section. OTHER RESTRICTIONS Mr. Lassiter will be subject to certain restrictions prohibiting him from engaging in competition with Ambac or any of our subsidiaries (except that these restrictions will not apply following a Change in Control) and from divulging any confidential or proprietary information he obtained while he was our employee. MANAGEMENT RETENTION AGREEMENTS WITH EXECUTIVE OFFICERS IN GENERAL We have entered into management retention agreements with each of our executive officers (other than Mr. Lassiter) to provide for payments and certain benefits if they are terminated following a "Change in Control" (as we define it below). 19 PAYMENTS If there is a Change in Control and, within three years AND BENEFITS of the Change in Control, the executive's employment is AFTER CHANGE IN terminated by Ambac or its successor other than for CONTROL "Cause" (as we define it below), or if the executive resigns for "Good Reason" (as we define it below), the executive will . receive cash payments equal to two times the sum of (a) the executive's highest annual base salary and (b) the product of the executive's highest bonus percentage (as a percentage of base salary) times his highest base salary; . be fully vested in all stock options and other awards under the 1991 Stock Incentive Plan and the 1997 Equity Plan; . receive a lump-sum payment equal to the amount that we would have contributed to the executive's account under the SIP and any nonqualified plan we maintained during the two years following termination; . be credited with an additional two years of service under the Pension Plan; and . continue to participate in Ambac's medical and other welfare benefits programs for a limited time following termination. All stock options and other awards under the 1997 Equity Plan that are made to executive officers after January 1, 1998 will vest in full upon the occurrence of a Change in Control, whether or not the executive's employment is subsequently terminated. The agreements also provide for a "gross up" payment in an amount that is intended to make the executive whole, on an after-tax basis, for any excise tax (but not any other tax) imposed on the payments described above. DEFINITIONS The following definitions are used in the Management Retention Agreements and the Employment Agreement with the Chief Executive Officer described above: "CHANGE IN CONTROL" A "Change in Control" generally occurs if . an individual, entity or group acquires beneficial ownership of 20% or more of the outstanding common stock. Acquisitions by Ambac and its affiliates or any employee benefit plan that they sponsor and certain acquisitions by persons who owned at least 15% of the outstanding shares of common stock on January 31, 1996 are not considered a change in control; 20 . the individuals who, as of January 29, 1997, constitute the Board, and subsequently elected members of the Board whose election is approved or recommended by at least a majority of these members or their successors whose election was so approved or recommended, cease for any reason to constitute at least a majority of the Board; or . our stockholders approve a merger or similar business combination, or a sale of all or substantially all of Ambac's assets, unless the Ambac stockholders immediately prior to the completion of the transaction will continue to own at least 70% of outstanding shares and voting power of the corporation that results from the transaction. "CAUSE" "Cause" for an executive's termination generally includes: . the willful commission of acts that are dishonest and demonstrably and materially injurious to Ambac; . the conviction of certain felonies; or . a material breach of any of the executive's agreements concerning confidentiality and proprietary information. An executive's termination will not be considered to have been for Cause unless at least three-quarters of the members of the Board adopt a resolution finding that the executive has engaged in conduct that constitutes Cause as defined in the agreement. "GOOD REASON" An executive will generally have "Good Reason" to terminate his employment if: . there is substantial adverse change in the executive's duties or responsibilities; . the office of the executive is relocated more than 25 miles from the location where the executive worked immediately prior to the Change in Control; or . Ambac fails to honor its obligations under the agreement. During a 30-day period following the first anniversary of a Change in Control, a resignation by the executive for any reason will be considered a termination for Good Reason. 21 REPORT ON EXECUTIVE COMPENSATION FOR 2001 BY THE COMPENSATION AND ORGANIZATION COMMITTEE The Compensation and Organization Committee of the Board administers Ambac's executive compensation program. The members of the Committee are independent non-employee, non-affiliated directors. The Committee has furnished the following report on executive compensation for 2001: WHAT IS OUR EXECUTIVE COMPENSATION PHILOSOPHY? The Committee has designed Ambac's executive compensation program to support what we believe to be an appropriate relationship between executive pay and the creation of stockholder value. To emphasize this relationship, we link a significant portion of executive compensation to the market performance of Ambac common stock. The objectives of our program are: . To support a pay-for-performance policy that differentiates bonus amounts among all executives based on both their individual performance, the performance of their respective groups and the performance of Ambac; . To align the interests of executives with the long-term interests of stockholders through stock option and restricted stock unit awards whose value over time depends upon the market value of Ambac's common stock; . To provide compensation comparable to that offered by other leading companies in our industry, enabling Ambac to compete for and retain talented executives who are critical to our long-term success; and . To motivate key executives to achieve strategic business initiatives and to reward them for their achievement. WHAT IS OUR POSITION ON MAXIMIZING THE DEDUCTIBILITY OF EXECUTIVE COMPENSATION? In 1997, our stockholders approved the 1997 Executive Incentive Plan ("EIP") and the 1997 Equity Plan. We designed these plans to allow Ambac to receive a tax deduction for incentive compensation payments to our Chief Executive Officer and our other four most highly paid executive officers. Without these qualifying performance-based plans, Ambac could not deduct incentive compensation payments to the extent the amounts paid to any of these executive officers in any year exceeded $1 million. The Committee intends to pursue a strategy of maximizing the deductibility of the compensation we pay to our executives. However, we intend to retain the flexibility to take actions that we consider to be in the best interests of Ambac and our stockholders and which may be based on considerations in addition to tax deductibility. 22 WHAT ARE THE ELEMENTS OF EXECUTIVE COMPENSATION? We compensate our executives through base salary, bonus (paid in a combination of cash and restricted stock units) and long-term incentive awards in the form of stock options. We target total compensation for our executive officers so that at least 50% (and in the case of the Chairman, 75%) consists of bonus and long term incentive awards. In this way, a significant portion of the value ultimately realized by the executives will depend upon Ambac's performance and can be considered "at risk." Our executives participate in retirement plans, health plans, and other voluntary benefit plans that we make available to all Ambac employees generally. We also provide our executives with long-term disability insurance for the cash bonus portion of their annual compensation. In addition, we offer our executives and managing directors a voluntary deferred compensation program. Ambac has also entered into management retention agreements with our executive officers to provide for certain payments and other benefits if they are terminated following a change in control of Ambac. These agreements, and the employment agreement with Ambac's Chief Executive Officer, which includes comparable change in control provisions, are discussed elsewhere in the Proxy Statement. HOW DID WE DETERMINE BASE SALARIES FOR 2001? IN GENERAL We annually review the base salaries of our executives to determine if adjustments are appropriate to ensure that their salaries are competitive and that they reflect the executive's increased responsibilities as Ambac grows. For executives other than the Chief Executive Officer, we also consider the recommendations of Mr. Lassiter, Ambac's Chairman and Chief Executive Officer. COMPARATIVE DATA In conducting our review for 2001, we considered comparative data prepared by both Ambac's senior human resources officer and by Johnson Associates, Inc., the Committee's outside consultant for executive compensation. The comparison group we chose for compensation purposes (the "COMPARISON GROUP") consisted mainly of our competitors in the financial guarantee insurance industry. The index we chose for our performance graph was the Investor's Business Daily Insurance Property/Casualty/Title Index. This was the publicly available index that we found best corresponded to our business and included the greatest number of companies in the Comparison Group. The performance graph follows this Report in the Proxy Statement. 23 We obtained data for the Comparison Group from a number of sources, including proxy statements, public information available from regulatory agencies and surveys by consulting firms. We used this comparative data as a benchmark in reaching our own determination of what were appropriate salary levels for our executives. BASE SALARIES OF Although the data for the Comparison Group supported an THE EXECUTIVES increase in base salaries for 2001, the Committee accepted Mr. Lassiter's recommendation to only increase those base salaries of those named executives who were promoted or had not received an increase last year. We note that the base salaries of our executives (excluding the Chief Executive Officer) are generally at or below the median for salaries of executives in the Comparison Group. The base salary for each of the named executive officers is reported in the "Summary Compensation Table" elsewhere in the Proxy Statement. BASE SALARY OF In light of our practice to only increase base salaries THE CHIEF of those Ambac executives who had not received an EXECUTIVE OFFICER increase in the previous year, the Committee did not increase the base salary of Mr. Lassiter for 2001. Mr. Lassiter's base pay remained at the 2000 level of $620,000. We note that Mr. Lassiter's base salary in 2001 was in the median for salaries of chief executive officers in the Comparison Group. HOW DID WE DETERMINE BONUSES FOR 2001? 2001 OVERALL In January 2002, the Committee evaluated Ambac's PERFORMANCE performance during 2001 under each of the nine categories set out in the EIP: return on equity; core/operating earnings growth; total return to stockholders; expense management; risk management; market share/position; industry leadership/image building; new products/initiatives; and organizational development/corporate culture. We did not weight the categories but instead arrived at an overall "grade" for corporate performance. We determined Ambac's overall performance to be quite strong with all performance categories ranked superior to excellent. BONUSES FOR The Committee awarded bonus compensation for 2001 to THE EXECUTIVES each executive based on the executive's scope of responsibility, individual performance and specific contribution to Ambac's overall performance. We again considered the Chief Executive Officer's recommendations and also took into account the comparative data. The bonus for each of the named executive officers is reported in the "Summary Compensation Table" elsewhere in the Proxy Statement. Under the Ambac Senior Officer Deferred Compensation Sub-Plan of the 1997 Equity Plan, 25% of each executive officer's bonus is paid in RSUs unless the executive officer has satisfied the stock ownership target under 24 the Ambac Stock Ownership Program. An executive who has met the ownership target may elect to receive 25% of his or her bonus in the form of RSUs. Except for Mr. Doyle, each executive officer elected to receive 25% of his bonus in the form of RSUs. Bonus amounts are reported in the Summary Compensation Table elsewhere in this Proxy Statement. The value we ascribed to the RSUs awarded under the Sub-Plan for 2001 was based on a 25% discount from the market value of Ambac's common stock on the date of grant. The Committee decided to discount these RSUs in order to account for vesting requirements and restrictions on transfer of the RSUs. Accordingly, the value we ascribed to the RSUs differs from the amounts reported in the Summary Compensation Table under the column headed "Annual Compensation--Restricted Stock Units", as those amounts, in accordance with SEC requirements, are based on the market price of the Common Stock on the date of grant. BONUSES FOR THE CHIEF At our meeting in January 2001, the Committee selected EXECUTIVE OFFICER Messers. Lassiter and Genader as the only executives to AND THE PRESIDENT participate in the EIP. We then established a formula under the EIP for determining Mr. Lassiter's and Mr. Genader's bonuses for the performance year. The formula emphasized return on equity and core earnings growth. In January 2002, we applied the formula and awarded Mr. Lassiter a bonus of $1,240,000 and Mr. Genader a bonus of $850,000. Although we had the authority to award a higher bonus under the formula for Messrs. Lassiter and Genader, in view of market conditions, we awarded Messrs. Lassiter and Genader less than the maximum amount under the formula. Pursuant to the Sub-Plan, Messrs. Lassiter and Genader elected to receive 25% of their bonuses in the form of RSUs having the terms described above. For 2002, we selected Messrs. Lassiter and Genader as the only executive officers to participate in the EIP. WHAT WERE THE LONG-TERM INCENTIVE AWARDS IN 2001? 2001 GRANTS In 2001, we provided long-term incentive awards for executives by granting stock options. These awards provide compensation to executives only if shareholder value increases. We believe these awards focus executives on the Company's long-term success. In determining the number of stock options awarded, we reviewed surveys of similar awards given by companies within the Comparison Group and the executive's past performance. We also considered the number of stock options previously granted to executives. This year, we decided to award again, performance-based stock options to all of our executive officers and managing directors. These options vest 25 only if the share price of Ambac's common stock meets certain targets. For 2001, each of the options granted to the executives will vest in two equal installments when the market price of Ambac common stock meets or exceeds $64.00 and $78.00 for twenty consecutive trading days or no later than the sixth anniversary of the grant date. As we have done since 1997, we again limited the term of the stock options to seven years. The number of stock options awarded to each of the executives (including Mr. Lassiter) was in the top quarter of recent awards given by companies within the Comparison Group. The number of stock options awarded to each of the named executive officers is reported in the "Option Grants in 2001" table elsewhere in the Proxy Statement. STOCK The Committee continues to apply our stock ownership OWNERSHIP guidelines to all managing directors and executive GUIDELINES officers. The guidelines set an appropriate level of ownership of Ambac stock (based on the market value of Ambac common stock) as a multiple of the officer's total cash compensation (base salary plus cash bonus). The multiple ranges from a high of seven times total cash compensation (in the case of Mr. Lassiter) to a low of one and one-half times total cash compensation for managing directors. Messrs. Lassiter, Genader, Bivona and Doyle have all met their stock ownership guidelines. The Committee believes these guidelines have the positive effect of further aligning the interests of the executives with all stockholders. THE COMPENSATION AND ORGANIZATION COMMITTEE Richard Dulude, Chairman Michael A. Callen Renso L. Caporali Jill M. Considine W. Grant Gregory March 22, 2002 26 PERFORMANCE GRAPH The graph below compares the five-year total return to stockholders (stock price appreciation plus reinvested dividends) for Ambac common stock with the comparable return of two indexes: the Standard & Poor's 500 Stock Index and the Investor's Business Daily Insurance--Property/Casualty/ Title Index. The graph assumes that you invested $100 in Ambac common stock and in each of the indexes on December 31, 1996, and that all dividends were reinvested. Points on the graph represent the performance as of the last business day of each of the years indicated. [CHART] Ambac Financial IBD-INS. Property/Casualty/ Group, Inc. S&P 500 Index Title Index --------------- ------------- --------------------------- 12/31/96 $100.0 $100.0 $100.0 12/31/97 139.9 133.4 123.1 12/31/98 184.3 171.5 98.4 12/31/99 161.0 207.6 74.8 12/31/00 272.1 188.7 105.0 12/31/01 271.6 166.2 91.0 If you had invested $100 in Ambac common stock on the date of our Initial Public Offering (July 18, 1991), your investment would have grown to approximately $923.91 by the end of 2001. This compares with a $100 investment growing to approximately $370.73 in the S&P 500 Index and to approximately $170.43 in the IBD Insurance Index. For this computation, we assumed that all dividends were reinvested, just as we did for the five-year total return comparison above. 27 DISCUSSION OF PROPOSALS RECOMMENDED BY THE BOARD PROPOSAL 1: ELECT SEVEN DIRECTORS The Board has nominated seven directors for election at the Annual Meeting.
