EXHIBIT 99.01 AMBAC ASSURANCE CORPORATION AND SUBSIDIARIES (a wholly-owned subsidiary of Ambac Financial Group, Inc.) Consolidated Financial Statements December 31, 2001 and 2000 Independent Auditors' Report The Board of Directors Ambac Assurance Corporation: We have audited the accompanying consolidated balance sheets of Ambac Assurance Corporation and subsidiaries (a wholly owned subsidiary of Ambac Financial Group, Inc.) as of December 31, 2001 and 2000, and the related consolidated statements of operations, stockholder's equity and cash flows for each of the years in the three-year period ended December 31, 2001. These consolidated financial statements are the responsibility of Ambac Assurance Corporation's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Ambac Assurance Corporation and subsidiaries as of December 31, 2001 and 2000, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2001 in conformity with accounting principles generally accepted in the United States of America. /s/ KPMG LLP KPMG LLP New York, New York January 23, 2002 AMBAC ASSURANCE CORPORATION AND SUBSIDIARIES Consolidated Balance Sheets December 31, 2001 and 2000 (Dollars in Thousands Except Share Data 2001 2000 ---------- ----------- ASSETS Investments: Fixed income securities, at fair value (amortized cost of $4,955,542 in 2001 and $3,969,932 in 2000) ................... $5,083,039 $4,098,511 Short-term investments, at cost (approximates fair value) ........................... 185,943 218,505 Other ............................................................................... 1,394 715 ---------- ---------- Total investments ............................................................... 5,270,376 4,317,731 Cash ..................................................................................... 33,678 11,893 Cash pledged as collateral ............................................................... -- 11,705 Securities purchased under agreements to resell .......................................... -- 25,016 Receivable for securities sold ........................................................... 281 1,215 Investment income due and accrued ........................................................ 73,456 67,132 Reinsurance recoverable .................................................................. 2,259 1,091 Prepaid reinsurance ...................................................................... 267,655 242,604 Deferred acquisition costs ............................................................... 163,477 153,424 Other assets ............................................................................. 343,866 230,908 ---------- ---------- Total assets .................................................................... $6,155,048 $5,062,719 ========== ========== LIABILITIES AND STOCKHOLDER'S EQUITY Liabilities: Unearned premiums ................................................................... $1,790,084 $1,556,250 Losses and loss adjustment expense reserve .......................................... 152,352 132,445 Ceded reinsurance balances payable .................................................. 10,146 10,892 Deferred income taxes ............................................................... 147,642 146,839 Current income taxes ................................................................ 126,039 31,308 Note payable to affiliate ........................................................... 63,500 -- Payable for securities purchased .................................................... 26,097 3,935 Other liabilities ................................................................... 362,465 255,308 ---------- ---------- Total liabilities ............................................................... 2,678,325 2,136,977 ---------- ---------- Stockholder's equity: Preferred stock, par value $1,000 per share; authorized shares-- 285,000; issued and outstanding shares-- none .......................... -- -- Common stock, par value $2.50 per share; authorized shares -- 40,000,000; issued and outstanding shares-- 32,800,000 at December 31, 2001 and December 31, 2000 ...................................... 82,000 82,000 Additional paid-in capital .......................................................... 928,094 760,006 Accumulated other comprehensive income .............................................. 80,556 81,616 Retained earnings ................................................................... 2,386,073 2,002,120 ---------- ---------- Total stockholder's equity ...................................................... 3,476,723 2,925,742 ---------- ---------- Total liabilities and stockholder's equity ...................................... $6,155,048 $5,062,719 ========== ========== See accompanying Notes to Consolidated Financial Statements.

See accompanying Notes to Consolidated Financial Statements. AMBAC ASSURANCE CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Thousands) 1 BACKGROUND Ambac Assurance Corporation is a leading provider of financial guarantees to clients in both the public and private sectors around the world. Ambac Assurance provides financial guarantees on public finance and structured finance obligations. Ambac Assurance has earned triple-A ratings, the highest ratings available from Moody's Investors Service, Inc., Standard & Poor's Ratings Services, Fitch, Inc., and Rating and Investment Information, Inc. Insurance policies insured by Ambac Assurance guarantee payment when due of the principal of and interest on the obligation guaranteed. Ambac Assurance is a wholly owned subsidiary of Ambac Financial Group, Inc., a holding company whose subsidiaries provide financial guarantees and financial services to clients in both the public and private sectors around the world. 2 SIGNIFICANT ACCOUNTING POLICIES The accompanying consolidated financial statements of Ambac Assurance and subsidiaries have been prepared on the basis of accounting principles generally accepted in the United States of America ("GAAP"). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant accounting policies of Ambac Assurance are as described below: CONSOLIDATION: The accompanying consolidated financial statements include the accounts of Ambac Assurance and its subsidiaries. The following companies have been consolidated with these financial statements: Ambac Assurance UK Limited, Ambac Credit Products, LLC, Connie Lee Holdings, Inc., Ambac Private Holdings, LLC, and Ambac Financial Services, L.P. All significant intercompany balances have been eliminated. INVESTMENTS: Ambac Assurance's investment portfolio is accounted for on a trade-date basis and consists primarily of investments in fixed income securities that are considered available-for-sale and are carried at fair value. Fair value is based primarily on quotes obtained from independent market sources. When quotes are not available, valuation models are used to estimate fair value. These models include estimates, made by management, which utilize current market information. The valuation results from these models could differ materially from amounts that would actually be realized in the market. Short-term investments are carried at cost, which approximates fair value. Unrealized gains and losses, net of deferred income taxes, are included as a component of "Accumulated Other Comprehensive Income" in stockholder's equity and are computed using amortized cost as the basis. For purposes of computing amortized cost, premiums and discounts are accounted for using the interest method. For bonds purchased at a price below par value, discounts are accreted over the remaining term of the securities. For bonds purchased at a price above par value which have call features, premiums are amortized to the most likely call dates as determined by management. For premium bonds that do not have call features, such premiums are amortized over the remaining terms of the securities. Premiums and discounts on mortgage-backed and asset-backed securities are adjusted for the effects of actual and anticipated prepayments. Realized gains and losses on the sale of investments are determined on the basis of specific identification. SECURITIES PURCHASED UNDER AGREEMENTS TO RESELL: Securities purchased under agreements to resell are collateralized investment transactions, and are recorded at their contracted resale amounts, plus accrued interest. Ambac Assurance takes possession of the collateral underlying those agreements and monitors its market value on a daily basis and, when necessary, requires prompt transfer of additional collateral to reflect current market value. At December 31, 2000, collateral underlying securities purchased under agreements to resell had an average credit rating of triple-A and a weighted average maturity of less than 30 days. DEFERRED ACQUISITION COSTS: Certain costs incurred, primarily related to the production of business, have been deferred. These costs include direct and indirect expenses related to underwriting, marketing and policy issuance, rating agency fees and premium taxes, net of reinsurance ceding commissions. The deferred acquisition costs are being amortized over the periods in which the related premiums are earned, and such amortization amounted to $28,203, $22,472 and $20,843 for 2001, 2000 and 1999, respectively. Deferred acquisition costs, net of such amortization, amounted to $10,053, $18,100 and $14,705 for 2001, 2000 and 1999, respectively. LOSSES AND LOSS ADJUSTMENT EXPENSE RESERVE: The reserve for losses and loss adjustment expenses consists of the active credit reserve and case basis loss and loss adjustment expense reserves. The development of the active credit reserve is based upon estimates of the expected levels of debt service defaults resulting from credit failures on currently guaranteed issues that are not presently or imminently in default. When losses occur (actual monetary defaults or defaults which are imminent on guaranteed obligations), case basis loss reserves are established in an amount that is sufficient to cover the present value of the anticipated defaulted debt service payments over the expected period of default and estimated expenses associated with settling the claims, less estimated recoveries under salvage or subrogation rights. During 2001, 2000 and 1999, paid losses were $2,595, $4,622, and $2,213, respectively. All or parts of case basis loss reserves are allocated from any active credit reserves available. During 2001, 2000 and 1999, salvage received were $1,333, $0 and $31, respectively. NET PREMIUMS EARNED: Up-front insurance premiums written are received for an entire bond issue. A bond issue may contain several maturities. The premium is allocated to each bond maturity proportionally, based on total principal amount guaranteed and is recognized on a straight-line basis over the term of each maturity. Installment insurance premiums written are recognized over each installment period, generally one year or less. When an issue insured by Ambac Assurance has been refunded or called, the remaining unrecognized premium (net of refunding credits, if any) is generally recognized at that time. DEPRECIATION AND AMORTIZATION: Depreciation of furniture and fixtures and electronic data processing equipment is provided over the estimated useful lives of the respective assets, ranging from three to five years, using the straight-line method. Amortization of leasehold improvements and intangibles, including certain computer software licenses, is provided over the estimated useful lives of the respective assets, ranging from three to 10 years, using the straight-line method. POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS: Ambac Financial Group, through its subsidiaries, provides various postretirement and postemployment benefits, including pension, and health and life benefits covering substantially all employees who meet certain age and service requirements. Ambac Assurance accounts for these benefits under the accrual method of accounting. Amounts related to the defined benefit pension plan and postretirement health benefits are charged based on actuarial determinations. FOREIGN CURRENCY: Financial statement accounts expressed in foreign currencies are translated into U.S. dollars in accordance with FAS Statement 52 "Foreign Currency Translation" ("SFAS 52"). Under SFAS 52, functional currency assets and liabilities are translated into U.S. dollars using exchange rates in effect at the balance sheet dates and the related translation adjustments are recorded as a separate component of comprehensive income, net of any related taxes. Functional currencies are generally the currencies of the local operating environment. Income statement accounts expressed in functional currencies are translated using average exchange rates. Foreign currency transaction gains and losses arising primarily from transactions in short-term investment securities and cash denominated in foreign currency are reflected in net income. The Consolidated Statements of Operations include pre-tax losses from such foreign exchange items of $3,370, $3,748 and $841 for 2001, 2000 and 1999, respectively. INCOME TAXES: Pursuant to a tax sharing agreement, Ambac Assurance is included in Ambac Financial Group, Inc.'s consolidated Federal income tax return. The tax sharing agreement provides for the determination of tax expense or benefit based on the contribution of Ambac Assurance to Ambac Financial Group's consolidated Federal income tax liability, computed substantially as if Ambac Assurance filed a separate Federal income tax return. The tax liability due is settled quarterly, with a final settlement taking place after the filing of the consolidated Federal income tax return. Ambac Assurance files its own state income tax returns. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. STOCK COMPENSATION PLANS: Ambac Assurance participates in Ambac Financial Group's equity plan. Under this plan, awards are granted to eligible employees of Ambac Assurance in the form of incentive stock options or other stock-based awards. Other than the tax benefits derived from this plan, pursuant to the tax sharing agreement, no other recognition is given by Ambac Assurance. DERIVATIVE CONTRACTS: In June 1998 the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Certain Hedging Activities." In June 2000 the FASB issued SFAS No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities (an amendment of SFAS 133)." SFAS No. 133 and SFAS No. 138 require all derivative instruments be recorded on the balance sheet at their respective fair values. SFAS No. 133 and SFAS No. 138 are effective for all fiscal quarters of all fiscal years beginning after June 30, 2000; Ambac Assurance adopted SFAS No.133 and SFAS No. 138 on January 1, 2001. In accordance with the transition provisions of SFAS 133, Ambac Assurance determined that it did not have an effect on the consolidated financial statements. Ambac Assurance, through its affiliate Ambac Financial Services, provides interest rate swaps to states, municipalities and their authorities, and other entities in connection with their financings. Ambac Financial Services also enters into total return swaps with professional counterparties. Total return swaps are only used for fixed income obligations, which meet Ambac Assurance's credit underwriting criteria. Ambac Financial Services uses futures contracts for hedging purposes as part of its overall interest rate risk management. Ambac Assurance, through its subsidiary Ambac Credit Products, enters into structured credit derivative transactions with various financial institutions. Ambac Financial Services interest rate swaps, total return swaps and futures contracts and Ambac Credit Product's structured credit derivatives are classified as held for trading purposes. These contracts are recorded on trade date at fair value. Changes in fair value are recorded as a component of other income for interest rate swaps, total return swaps and futures contracts on the Consolidated Statements of Operations. The fee component of structured credit derivatives is reflected in other credit enhancement fees in the accompanying Consolidated Statement of Operations. The mark to market gain or loss associated with credit spread changes on structured credit derivatives is reflected in net realized losses in the accompanying Consolidated Statement of Operations. Amounts included in net realized losses for credit spread mark-to-market were $3,588, $4,111 and $0 for the years ended December 31, 2001, 2000 and 1999, respectively. The fair values of interest rate swaps and structured credit derivatives are determined by broker quotes, independent pricing services or valuation models (when broker quotes or pricing services are not available). Valuation models include estimates, made by management, which utilize current market information. The valuation results from these models could differ materially from amounts that would actually be realized in the market. Contracts are recorded on the Consolidated Balance Sheets on a gross basis; assets and liabilities are netted by customer only when a legal right of set-off exists. Gross asset and gross liability balances for interest rate swaps and structured credit derivatives are recorded as other assets or other liabilities on the Consolidated Balance Sheets. SPECIAL PURPOSE ENTITIES: Ambac Financial Group, Inc. has sponsored two special purpose entities. The business purpose of these entities is to provide certain financial guarantee clients with funding for their debt obligations. Ambac Assurance receives financial guarantee premiums and may receive other fees for this service. Ambac Financial Group accounts for these entities as Qualified Special Purpose Entities ("QSPEs") in accordance with Statement of Financial Accounting Standards 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." The QSPEs are non-consolidated, bankruptcy remote entities. Ambac purchases debt obligations from certain financial guarantee clients and sells these obligations to the QSPEs. The purchase by the QSPE is financed through the issuance of medium-term notes ("MTNs"), which are collateralized by the purchased assets. These MTNs are generally structured to match the cash flow of the assets purchased. Derivative contracts may be used (interest rate and currency swaps) for hedging purposes only. Derivative hedges are established at the time MTNs are issued to purchase financial assets. Ambac Assurance may issue a financial guarantee insurance policy on the assets sold, the MTNs issued or both. As of December 31, 2001, Ambac Assurance had insurance policies issued for all assets and MTNs owned and outstanding by the QSPEs. Since these exposures are insured, any losses incurred would be included in Ambac Assurance's Consolidated Statements of Operations. Under the terms of an Administrative Agency Agreement, Ambac Financial Group provides certain administrative duties, including asset and liability servicing responsibilities. Assets sold to the QSPEs during 2001, 2000 and 1999 were $793,438, $159,937 and $100,027, respectively. No gains or losses were recognized on these sales. As of December 31, 2001, the estimated fair value of financial assets, MTN liabilities and derivative hedge assets were $989,905, $1,003,588 and $11,677, respectively. Estimated fair value is determined utilizing valuation models. These models include estimates, made by management, which utilize current market information. The valuation results from these models could differ materially from amounts that would actually be realized in the market. Ambac Assurance received gross premiums and other fees for issuing financial guarantee policies on the assets and MTNs of $23,682, $3,204, and $1,019 for the years ended December 31, 2001, 2000 and 1999, respectively. Ambac Financial Group received up-front fees for providing administrative agency services amounting to $302, $180, and $60 for 2001, 2000 and 1999 respectively. ACCOUNTING STANDARDS: In July 2001, the FASB issued FAS Statement 142, "Goodwill and Other Intangible Assets" ("SFAS142".) SFAS 142 addresses the initial recognition and measurement of intangible assets either singly or within a group of assets, as well as the measurement of goodwill and other intangible assets subsequent to their initial acquisition. SFAS 142 changes the accounting for goodwill and intangible assets that have indefinite useful lives from an amortization approach to an impairment-only approach that requires that those assets be tested at least annually for impairment. Intangible assets that have finite useful lives will continue to be amortized over their useful lives, but without an arbitrary ceiling on their useful lives. SFAS 142 is required to be applied starting with fiscal years beginning after December 15, 2001 and is required to be applied at the beginning of an entity's fiscal year. The statement is to be applied to all goodwill and other intangible assets recognized in an entity's financial statements at that date. Impairment losses for goodwill and indefinite lived intangible assets that arise due to the initial application of SFAS 142 (resulting from an impairment test) are to be reported as a change in accounting principle. Retroactive application is not permitted. In August 2001, the FASB issued FAS Statement 143, "Accounting for Asset Retirement Obligations"("SFAS 143".) SFAS 143 requires companies to record the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. Companies also record a corresponding asset which is depreciated over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation. Ambac Assurance is required to adopt SFAS 143 on January 1, 2003. In October 2001, the FASB issued FAS Statement 144, "Accounting for the Impairment or Disposal of Long-Lived Assets"("SFAS 144".) SFAS 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This Statement requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. SFAS Statement 144 requires companies to separately report discontinued operations and extends that reporting to a component of an entity that either has been disposed of (by sale, abandonment, or in a distribution to owners) or is classified as held for sale. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Ambac Assurance is required to adopt SFAS 144 on January 1, 2002. Ambac Assurance does not expect any material impact from the adoption of SFAS 142, SFAS 143 or SFAS 144. RECLASSIFICATIONS: Certain reclassifications have been made to prior years' amounts to conform to the current year's presentation. 3 INVESTMENTS The amortized cost, gross unrealized gains and losses, and estimated fair value of investments in fixed income securities and short-term investments at December 31, 2001 and 2000 were as follows: Gross Gross Estimated Amortized Unrealized Unrealized Fair Cost Gains Losses Value ---------- ---------- ----------- ---------- 2001 Municipal obligations .............................. $3,439,356 $ 129,826 $ 28,887 $3,540,295 Corporate obligations .............................. 644,216 22,762 10,777 656,201 Foreign government obligations ..................... 97,108 629 1,137 96,600 U.S. government obligations ........................ 51,182 3,582 -- 54,764 Mortgage and asset-backed securities (includes U.S. government agency obligations) ................ 723,680 13,018 1,519 735,179 Short-term ......................................... 185,943 -- -- 185,943 ---------- ---------- ----------- ---------- $5,141,485 $ 169,817 $ 42,320 $5,268,982 ========== ========== =========== ========== Gross Gross Estimated Amortized Unrealized Unrealized Fair Cost Gains Losses Value ---------- ---------- ----------- ---------- 2000 Municipal obligations .............................. $3,206,089 $ 140,244 $ 17,591 $3,328,742 Corporate obligations .............................. 422,200 13,398 13,465 422,133 Foreign government obligations ..................... 36,241 83 954 35,370 U.S. government obligations ........................ 46,396 3,012 1 49,406 Mortgage and asset-backed securities (includes U.S. government agency obligations) ................ 259,006 5,581 1,728 262,860 Short-term ......................................... 218,505 -- -- 218,505 ---------- ---------- ----------- ---------- $4,188,437 $ 162,318 $ 33,739 $4,317,016 ========== ========== =========== ========== The amortized cost and estimated fair value of fixed income securities and short-term investments at December 31, 2001, by contractual maturity, were as follows: Amortized Estimated Cost Fair Value ------------- ------------- 2001 Due in one year or less .............................................. $ 221,676 $ 222,079 Due after one year through five years ................................ 531,357 547,027 Due after five years through ten years ............................... 640,684 653,572 Due after ten years .................................................. 3,024,088 3,111,125 ------------- ------------- 4,417,805 4,533,803 Mortgage and asset-backed securities (includes U.S. government agency obligations) .................................................. 723,680 735,179 ------------- ------------- $ 5,141,485 $ 5,268,982 ============= ============= Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities carried at $5,964 and $5,843 at December 31, 2001 and 2000 respectively, were deposited by Ambac Assurance with governmental authorities or designated custodian banks as required by laws affecting insurance companies.

The effect of reinsurance on premiums written and earned was as follows: Year Ended December 31, -------------------------------------------------------------------------- 2001 2000 1999 ---------------------- ---------------------- ---------------------- Written Earned Written Earned Written Earned --------- --------- --------- --------- --------- --------- Direct .......... $ 636,574 $ 414,700 $ 442,714 $ 338,139 $ 425,213 $ 291,983 Assumed ......... 50,883 38,825 42,971 32,530 24,573 19,161 Ceded ...........

In the event that all or any of the reinsurers are unable to meet their obligations to Ambac Assurance under the existing reinsurance agreements, Ambac Assurance would be liable for such defaulted amounts. To minimize its exposure to significant losses from reinsurer insolvencies, Ambac Assurance evaluates the financial condition of its reinsurers and monitors concentrations of credit risk. As of December 31, 2001, Ambac Assurance held letters of credit and collateral amounting to approximately $282,832 from its reinsurers to cover liabilities ceded under the aforementioned reinsurance contracts. There were no reinsurance recoverables on paid losses as of December 31, 2001 and 2000. As of December 31, 2001, prepaid reinsurance of approximately $169,430 was associated with Ambac Assurance's three largest reinsurers. Ambac Assurance pledged cash and fixed income securities to foreign insurers of $9,295 and $9,386 at December 31, 2001 and 2000, respectively, related to business assumed from those insurers. From 1995 to March 2000, Ambac Assurance and MBIA Insurance Corporation ("MBIA") marketed financial guarantees outside of the United States via an unincorporated joint venture, MBIAoAMBAC International (the "Joint Venture"). Under the Joint Venture, financial guarantee policies were issued separately by each of the companies. While retaining the right to act individually, each company had the opportunity to reinsure up to 50 percent of the international financial guarantee business written by the other company as part of the Joint Venture. Premiums assumed from MBIA relating to international business were $46,211, $37,384 and $24,503 in 2001, 2000 and 1999, respectively, while premiums ceded to MBIA were $21,994, $36,807 and $27,418 in 2001, 2000 and 1999, respectively. 5 LOSSES AND LOSS ADJUSTMENT EXPENSE RESERVE As discussed in note 2, Ambac Assurance's liability for losses and loss adjustment expenses consists of case basis and active credit reserves. Following is a summary of the activity in the case basis loss and active credit reserve accounts and the components of the liability for loss and loss adjustment expense reserves: 2001 2000 1999 --------- --------- --------- Case basis loss and loss adjustment expense reserves: Balance at January 1 ....................................... $ 32,125 $ 26,705 $ 37,554 Less: reinsurance recoverables ........................... 1,091 501 3,638 --------- --------- --------- Net Balance at January 1 ................................... 31,034 26,204 33,916 --------- --------- --------- Incurred related to: Current year ............................................. 3,000 -- 4,000 Prior years ..............................................

The lease agreements, which expire periodically through September 2019, contain provisions for scheduled periodic rent increases and are accounted for as operating leases. An estimate of future net minimum lease payments in each of the next five years ending December 31, and the periods thereafter, is as follows: Amount ------------ 2002 ...................................... $ 5,909 2003 ...................................... 5,759 2004 ...................................... 5,760 2005 ...................................... 5,773 2006 ...................................... 5,787 All later years ........................... 77,329 ------------ $106,317 ============ Rent expense for the aforementioned leases amounted to $5,916, $5,549 and $5,298 for the years ended December 31, 2001, 2000 and 1999, respectively. 7 INSURANCE REGULATORY Ambac Assurance is subject to the insurance regulatory requirements of the States of Wisconsin and New York, and the other jurisdictions in which it is licensed to conduct business. Ambac Assurance's ability to pay dividends is generally restricted by law and subject to approval by the Office of the Commissioner of Insurance of the State of Wisconsin. Wisconsin insurance law restricts the payment of dividends in any 12-month period without regulatory approval to the lesser of (a) 10% of policyholders' surplus as of the preceding December 31 and (b) the greater of (i) statutory net income for the calendar year preceding the date of dividend, minus realized capital gains for that calendar year and (ii) the aggregate of statutory net income for three calendar years preceding the date of the dividend, minus realized capital gains for those calendar years and minus dividends paid or credited within the first two of the three preceding calendar years. Based upon these restrictions, at December 31, 2001, the maximum amount that will be available during 2002 for payment of dividends by Ambac Assurance is approximately $200,000. Ambac Assurance paid cash dividends of $68,000, $59,800 and $52,000 on its common stock in 2001, 2000 and 1999, respectively. The New York Financial Guarantee Insurance Law establishes single risk limits applicable to all obligations issued by a single entity and backed by a single revenue source. Such limits are specific to the type of insured obligation (for example, municipal or asset-backed). The limits compare the insured net par outstanding and average annual debt service, net of reinsurance and collateral, for a single risk to the insurer's qualified statutory capital, which is defined as the sum of the insurer's policyholders' surplus and contingency reserves. As of December 31, 2001 and 2000, Ambac Assurance and its subsidiaries were in compliance with these regulatory requirements. Ambac Assurance's statutory financial statements are prepared on the basis of accounting practices prescribed or permitted by the Wisconsin Insurance Department. Effective January 1, 2001, Wisconsin adopted the National Association of Insurance Commissioners' statutory accounting practices as the basis of its statutory accounting practices. The adoption of the National Association of Insurance Commissioners' accounting practices did not have a material effect on Ambac Assurance's statutory capital. The commissioner of the Wisconsin Insurance Department has the right to permit specific practices that deviate from prescribed practices. Ambac Assurance does not have any accounting practices that are permitted, rather than prescribed, by the Insurance Department of the State of Wisconsin. Statutory capital and surplus differs from stockholder's equity determined under GAAP principally due to statutory accounting rules that treat loss reserves, premiums earned, policy acquisition costs, deferred income taxes and investment carrying values differently. The following is a reconciliation of consolidated stockholder's equity presented on a GAAP basis for Ambac Assurance and its consolidated subsidiaries to statutory capital and surplus for Ambac Assurance: For the Years Ended December 31, -------------------------------------- 2001 2000 ---------------- --------------- Ambac Assurance Corporation GAAP stockholder's equity ............ $3,476,723 $2,925,742 Mandatory contingency reserve ...........................

The benefits are based on years of service and the employee's highest salary during five consecutive years of employment within the last ten years of employment. Ambac Financial Group's funding policy is to contribute annually the maximum amount that can be deducted for Federal income tax purposes. Contributions are intended to provide not only for benefits attributed to service-to-date but also for those expected to be earned in the future. The table below sets forth a reconciliation of the beginning and ending projected benefit obligation, beginning and ending balances of the fair value of plan assets, and the funded status of the plan as of December 31, 2001 and 2000: 2001 2000 ------------- ---------- Change in Projected Benefit Obligation: Projected benefit obligation at beginning of year ............................ $12,669 $11,201 Service cost ................................................................. 1,031 892 Interest cost ................................................................ 853 829 Actuarial (gain) loss ........................................................

Pension expense recorded by Ambac Assurance amounted to $281, $375 and $553 in 2001, 2000 and 1999, respectively. The discount rate used in the determination of the actuarial present value for the projected benefit obligation was 7.0% and 7.5% for 2001 and 2000, respectively. The expected long-term rate of return on assets was 9.25% for both 2001 and 2000. The rate of increase in future compensation levels used in determining the actuarial present value of the projected benefit obligation was 4.5% and 5.0% for 2001 and 2000, respectively. Substantially all employees of Ambac Financial Group and its subsidiaries are covered by a defined contribution plan (the "Savings Incentive Plan"), for which contributions and costs are determined as 6% of each eligible employee's eligible base salary, plus a matching company contribution of 50% on contributions up to 6% of base salary made by eligible employees to the Savings Incentive Plan. The total cost of the Savings Incentive Plan to Ambac Assurance was $2,188, $1,940 and $1,695 in 2001, 2000 and 1999, respectively. Annual Incentive Program: Ambac Financial Group has an annual incentive program that provides for awards to key officers and employees based upon predetermined criteria. Ambac Assurance's cost of the program for the years ended December 31, 2001, 2000 and 1999 amounted to $24,927, $21,055 and $16,106, respectively. Postretirement Health Care and Other Benefits: Ambac Financial Group provides certain medical and life insurance benefits for retired employees and eligible dependents. All plans are contributory. None of the plans are currently funded. Ambac Assurance's postretirement benefits expense was $113, $328 and $456 in 2001, 2000 and 1999, respectively. Ambac Financial Group's unfunded accumulated postretirement benefit obligation was $1,727, and the accrued postretirement liability was $2,504 as of December 31, 2001. The assumed health care cost trend rates range from 7.5% in 2002, decreasing ratably to 6.0% in 2008, and remaining at that level thereafter. Increasing the assumed health care cost trend rate by one percentage point in each future year would increase Ambac Financial Group's accumulated postretirement benefit obligation at December 31, 2001 by $639 and Ambac Financial Group's 2001 benefit expense by $103. The discount rate used to measure the accumulated postretirement benefit obligation and 2001 expense was 7.0%. 10 GUARANTEES IN FORCE The par amount of bonds guaranteed, for non-affiliates, were $357,219,000 and $313,475,000 at December 31, 2001 and 2000, respectively. The par amount of bonds guaranteed, for non-affiliates, net of reinsurance, were $318,043,000 and $276,252,000 at December 31, 2001 and 2000, respectively. As of December 31, 2001 and 2000, the guarantee portfolio was diversified by type of guaranteed bond as shown in the following table: Net Par Amount Outstanding -------------------------------- (Dollars in Millions) 2001 2000 ------------- ---------- Public Finance: Lease and tax-backed revenue ............................................ $ 52,102 $ 46,292 General obligation ...................................................... 39,664 39,432 Utility revenue ......................................................... 29,513 28,504 Health care revenue ..................................................... 19,003 17,837 Transportation revenue .................................................. 13,000 10,496 Higher education ........................................................ 11,854 9,603 Investor-owned utilities ................................................ 11,642 10,560 Housing revenue ......................................................... 7,476 7,146 Student loans ........................................................... 7,249 6,375 Other ................................................................... 5,103 4,065 -------- -------- Total Public Finance ................................................ 196,606 180,310 -------- -------- Structured Finance: Mortgage-backed and home equity ......................................... 42,723 38,215 Asset-backed and conduits ............................................... 23,302 22,121 Other ................................................................... 6,612 4,324 -------- -------- Total Structured Finance ............................................ 72,637 64,660 -------- -------- International Finance: Structured credit derivatives ........................................... 26,123 15,313 Asset-backed and conduits ............................................... 11,721 8,595 Utilities ............................................................... 2,878 1,803 Mortgage-backed and home equity ......................................... 2,602 1,364 Sovereign/sub-sovereign ................................................. 1,299 1,123 Other ................................................................... 4,177 3,084 -------- -------- Total International Finance ......................................... 48,800 31,282 -------- -------- $318,043 $276,252 ======== ======== As of December 31, 2001 and 2000, the International Finance guarantee portfolio is shown in the following table by location of risk: Net Par Amount Outstanding ----------------------------------------------- (Dollars in Millions) 2001 2000 --------------------- --------------------- United Kingdom ........................... $ 6,531 $ 3,103 Australia ................................ 1,623 1,382 Japan .................................... 1,167 1,167 France ................................... 1,155 765 Germany .................................. 948 471 Mexico ................................... 654 608 Internationally diversified .............. 32,621 20,962 Other international ...................... 4,101 2,824 --------------------- --------------------- $48,800 $31,282 ===================== ===================== Internationally diversified includes structured credit derivatives which includes components of domestic exposure. Direct financial guarantees in force (principal and interest) were $542,458,000 and $480,631,000 at December 31, 2001 and 2000, respectively. Net financial guarantees in force (after giving effect to reinsurance) were $476,190,000 and $418,386,000 as of December 31, 2001 and 2000, respectively. In the United States, California and New York were the states with the highest aggregate net par amounts in force, accounting for 8.8% and 5.7% of the total at December 31, 2001. No other state accounted for more than five percent. The highest single insured risk represented less than 1% of aggregate net par amount insured. 11 FAIR VALUES OF FINANCIAL INSTRUMENTS The following fair value amounts were determined by using independent market information when available, and valuation models when market quotes were not available. In cases where specific market quotes are unavailable, interpreting market data and estimating market values require considerable judgment by management. Accordingly, the estimates presented are not necessarily indicative of the amount Ambac Assurance could realize in a current market exchange. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Investments: The fair values of fixed income investments are based primarily on quoted market prices received from a nationally recognized pricing service or dealer quotes. When quotes are not available, fair values are estimated based upon internal valuation models. Short-term investments, other investments and cash: The fair values of short-term investments, other investments and cash are assumed to approximate amortized cost. Securities purchased under agreements to resell: The fair value of securities purchased under agreements to resell is assumed to approximate carrying value. Investment income due and accrued: The fair value of investment income due and accrued is assumed to approximate carrying value. Derivative contracts held for trading purposes: The fair values of interest rate swaps, total return swaps and structured credit derivative transactions, as discussed in Note 2, are based on quoted dealer prices, current settlement values, or valuation models. Note payable to affiliate: The fair value of the note payable is assumed to equal carrying value. Liability for net financial guarantees written: The fair value of the liability for those financial guarantees written is based on the estimated cost to reinsure those exposures at current market rates, which amount consists of the current unearned premium reserve, less an estimated ceding commission thereon. Other financial guarantee insurance policies have been written on an installment basis, where the future premiums to be received by Ambac Assurance are determined based on the outstanding exposure at the time the premiums are due. The fair value of Ambac Assurance's liability under its installment premium policies is measured using the present value of estimated future installment premiums, less an estimated ceding commission.

This note pays interest quarterly at 0.2% below three month LIBOR, currently at 1.71%. Ambac Financial Group and Ambac Assurance have a revolving credit facility with four major international banks for $200,000, which expires in August 2002 and provides a two-year term loan provision. The facility is available for general corporate purposes, including the payment of claims. As of December 31, 2001 and 2000, no amounts were outstanding under this credit facility. Ambac Credit Products has a revolving credit facility with one major international bank for $50,000, which expires in June 2002, and provides for a three-year term loan provision. The facility is available to Ambac Credit Products for general corporate purposes, including payments in regard to its structured credit derivative activities. As of December 31, 2001 and 2000, no amounts were outstanding under this credit facility. Ambac Assurance maintains third-party capital support in the form of seven-year irrevocable limited recourse credit facility from a group of highly rated banks. This credit facility provides liquidity to Ambac Assurance in the event claims from public finance and certain structured obligations in its guaranteed portfolios exceed specified levels. Repayment of amounts drawn under the credit facility is limited primarily to the amount of any recoveries of losses related to policy obligations in the guaranteed portfolios. During 2001, Ambac Assurance replaced a portion of the facility with a new capital markets structure (see below). Consequently, the facility was reduced from $800,000 to $400,000. The facility's expiration date was also extended to June 30, 2008. As of December 31, 2001 and 2000, no amounts were outstanding under this facility. Ambac Assurance acquired a perpetual put option on its own preferred stock from a trust established by a major investment bank. The trust was created as a vehicle for providing capital support to Ambac Assurance by allowing it to obtain immediate access to new capital at its sole discretion at any time through the exercise of the put option. If the put option were exercised, the preferred stock holdings of Ambac Assurance would give investors the rights of an equity investor in Ambac Assurance. Such rights are subordinate to insurance claims, as well as to the general unsecured creditors of Ambac Assurance. If exercised, Ambac Assurance would receive up to $400,000 in return for the issuance of its own perpetual preferred stock, the proceeds of which may be used for any purpose including the payment of claims. Dividend payments on the preferred stock are cumulative only if Ambac Assurance pays dividends on its common stock. The trust is a special purpose trust that is restricted to holding high quality short-term commercial paper investments to ensure that it can meet its obligations under the put option. To fund these investments, the trust has issued its own auction market perpetual preferred stock. Ambac Assurance pays a floating put option fee. The trust is rated AA/Aa2 by Standard & Poor's and Moody's respectively. 13 RELATED PARTY TRANSACTIONS During 2001 and 2000, Ambac Assurance guaranteed the timely payment of principal and interest on obligations under investment agreements and investment repurchase agreements issued by its affiliates.
