EXHIBIT 99.07 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES (a wholly owned subsidiary of AMBAC Inc.) Consolidated Financial Statements December 31, 1996 and 1995 INDEPENDENT AUDITORS' REPORT The Board of Directors AMBAC Indemnity Corporation We have audited the accompanying consolidated balance sheets of AMBAC Indemnity Corporation and subsidiaries (a wholly owned subsidiary of AMBAC Inc.) as of December 31, 1996 and 1995, 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, 1996. These consolidated financial statements are the responsibility of AMBAC Indemnity 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 generally accepted auditing standards. 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 Indemnity Corporation and subsidiaries as of December 31, 1996 and 1995, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 1996 in conformity with generally accepted accounting principles. /s/ KPMG Peat Marwick LLP New York, New York January 30, 1997 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES CONSOLIDATED BALANCE SHEETS DECEMBER 31, 1996 AND 1995 (DOLLARS IN THOUSANDS EXCEPT SHARE DATA) 1996 1995 ---------- ---------- ASSETS Investments: Bonds held in available for sale account, at fair value (amortized cost of $2,323,259 in 1996 and $2,090,101 in 1995).................................................. $2,424,524 $2,224,528 Short-term investments, at cost (approximates fair value)................................................. 91,320 163,953 ---------- ---------- Total investments...................................... 2,515,844 2,388,481 Cash..................................................... 5,025 6,912 Securities purchased under agreements to resell.......... 4,369 4,120 Receivable for securities................................ 18,462 8,136 Investment income due and accrued........................ 42,263 38,319 Investment in affiliate.................................. -- 25,827 Deferred acquisition costs............................... 94,212 82,620 Current income taxes..................................... -- 2,171 Prepaid reinsurance...................................... 168,786 153,372 Other assets............................................. 59,544 48,472 ---------- ---------- Total assets........................................... $2,908,505 $2,758,430 ========== ========== LIABILITIES AND STOCKHOLDER'S EQUITY Liabilities: Unearned premiums....................................... $ 995,220 $ 906,136 Losses and loss adjustment expenses..................... 60,220 65,996 Ceded reinsurance balances payable...................... 7,438 14,654 Deferred income taxes................................... 84,842 85,008 Current income taxes.................................... 8,974 -- Accounts payable and other liabilities.................. 50,244 43,625 Payable for securities.................................. 46,246 86,304 ---------- ---------- Total liabilities...................................... 1,253,184 1,201,723 ---------- ---------- Stockholder's equity: Preferred stock, par value $1,000.00 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, 1996 and December 31, 1995......................... 82,000 82,000 Additional paid-in capital.............................. 515,684 481,059 Unrealized gains on investments, net of tax............. 65,822 87,112 Retained earnings....................................... 991,815 906,536 ---------- ---------- Total stockholder's equity............................. 1,655,321 1,556,707 ---------- ---------- Total liabilities and stockholder's equity............. $2,908,505 $2,758,430 ========== ========== See accompanying Notes to Consolidated Financial Statements 1 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES CONSOLIDATED STATEMENTS OF OPERATIONS (DOLLARS IN THOUSANDS) YEARS ENDED DECEMBER 31, ---------------------------- 1996 1995 1994 -------- -------- -------- Revenues: Gross premiums written........................... $249,761 $195,033 $192,598 Ceded premiums written...........................

Financial guarantee insurance underwritten by AMBAC Indemnity guarantees payment when due of the principal of and interest on the obligation insured. In the case of a default on the insured bond, payments under the insurance policy may not be accelerated by the policyholder without AMBAC Indemnity's consent. As of December 31, 1996, AMBAC Indemnity's net insurance in force (principal and interest) was $227,235,000. AMBAC Indemnity is a wholly owned subsidiary of AMBAC Inc. (NYSE: ABK), a holding company that provides financial guarantee insurance and financial services to both public and private clients through its subsidiaries. AMBAC Indemnity, as the sole limited partner, owns a limited partnership interest representing 90% of the total partnership interests of AMBAC Financial Services, Limited Partnership ("AFS"), a limited partnership which provides interest rate swaps primarily to states, municipalities and municipal authorities. The sole general partner of AFS, AMBAC Financial Services Holdings, Inc., a wholly owned subsidiary of AMBAC Inc., owns a general partnership interest representing 10% of the total partnership interest in AFS. AMBAC Indemnity has one wholly owned subsidiary, American Municipal Bond Holding Company ("AMBH"), which is a holding company for certain real estate interests. As of December 31, 1995, AMBAC Indemnity owned 26.5% and AMBAC Inc. owned 19.9% of the outstanding common stock of an affiliate, HCIA Inc. ("HCIA"), a leading health care information content company. Prior to 1995, AMBAC Inc. and AMBAC Indemnity, combined, owned approximately 96% of HCIA. During 1996, in conjunction with the sale of AMBAC Inc.'s and AMBAC Indemnity's combined holdings in HCIA common stock, AMBAC Indemnity delivered to AMBAC Inc. (in the form of an extraordinary dividend) its 2,378,672 shares of HCIA common stock. As a result, AMBAC Indemnity recognized a realized gain of $89,680. 2 SIGNIFICANT ACCOUNTING POLICIES The accompanying consolidated financial statements have been prepared on the basis of generally accepted accounting principles ("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 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 Indemnity and its subsidiaries (sometimes collectively referred to as the "Company") are as described below: CONSOLIDATION: The consolidated financial statements include the accounts of AMBAC Indemnity and its subsidiaries. All significant intercompany balances have been eliminated. INVESTMENTS: The Company's investment portfolio is accounted for on a trade-date basis and consists entirely of investments in debt securities that are considered available for sale and are carried at fair value. Fair value is based on quotes 5 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) obtained by the Company from independent market sources. Short-term investments are carried at cost, which approximates fair value. Unrealized gains and losses, net of deferred income taxes, are included as a separate component of 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 which do not have call features, such premiums are amortized over the remaining terms of the securities. Premiums and discounts on mortgage- 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 financing transactions, and are recorded at their contracted resale amounts, plus accrued interest. The Company 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. PREMIUM REVENUE RECOGNITION: Premiums for municipal new issue and secondary market policies are: (i) generally computed as a percentage of principal and interest insured; (ii) typically collected in a single payment at policy inception date; and (iii) are earned pro rata over the period of risk. Premiums for structured finance policies can be computed as a percentage of either principal or principal and interest insured. The timing of the collection of structured finance premiums varies among individual transactions. For policies where premiums are collected in a single payment at policy inception date, premiums are earned pro rata over the period of risk. For policies with premiums that are collected periodically (i.e., monthly, quarterly or annually), premiums are reflected in income pro rata over the period covered by the premium payment. When an AMBAC Indemnity-insured new or secondary market issue has been refunded or called, the remaining unearned premium is generally earned at that time, as the risk to AMBAC Indemnity is considered to have been eliminated. LOSSES AND LOSS ADJUSTMENT EXPENSES: The liability for losses and loss adjustment expenses consists of the Active Credit Reserve ("ACR") and case basis loss and loss adjustment expense reserves. The development of the ACR is based upon estimates of the ultimate aggregate losses inherent in the obligations insured and reflects the net result of contributions related to the portion of earnings required to cover those losses, less reductions of ACR no longer deemed necessary by management. When losses occur (actual monetary defaults or defaults which are imminent on insured 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. All or part of case basis loss reserves are allocated from any ACR available for such insured obligation. 6 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) AMBAC Indemnity's management believes that the reserves for losses and loss adjustment expenses are adequate to cover the ultimate net cost of claims, but the reserves are necessarily based on estimates and there can be no assurance that the ultimate liability will not exceed such estimates. DEFERRED ACQUISITION COSTS: Certain costs incurred which vary with, and are 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 $12,553, $10,183 and $9,348 for 1996, 1995 and 1994, respectively. Deferred acquisition costs, net of such amortization, amounted to $11,592, $10,846 and $20,757 for 1996, 1995 and 1994, respectively. DEPRECIATION AND AMORTIZATION: Depreciation of furniture and fixtures and electronic data processing equipment is provided over the estimated useful lives of the respective assets 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 using the straight-line method. INTEREST RATE CONTRACTS: Interest Rate Contracts Held for Purposes Other Than Trading: The Company uses interest rate contracts for hedging purposes as part of its overall interest rate risk management. Gains and losses on interest rate futures and options contracts that qualify as accounting hedges of existing assets are included in the carrying amounts and amortized over the remaining lives of the assets as an adjustment to interest income. When the hedged asset is sold, the unamortized gain or loss on the related hedge is recognized in income. Gains and losses on interest rate contracts that do not qualify as accounting hedges are recognized in current period income. The Company accounts for its interest rate futures contracts in accordance with the provisions of Statement of Financial Accounting Standards No. 80, "Accounting for Futures Contracts" ("Statement 80"). Statement 80 permits hedge accounting for interest rate futures contracts when the item to be hedged exposes the Company to price or interest rate risk, and the futures contract effectively reduces that exposure and is designated as a hedge. Interest rate futures contracts held for purposes other than trading are used primarily to hedge interest-sensitive assets and liabilities. Interest rate futures contracts are designated at inception as a hedge to specific assets and liabilities. Interest rate swaps that are linked with existing liabilities are accounted for as a hedge of those liabilities, using the accrual method as an adjustment to interest expense. Interest rate swaps that are linked with existing assets classified as available for sale are accounted for as hedges of those assets, using the accrual method as an adjustment to interest income, with unrealized gains and losses included in stockholder's equity, net of tax. 7 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) Interest Rate Contracts Held for Trading Purposes: The Company, in connection with its market-making activities as a provider of interest rate swaps to states, municipalities, municipal authorities and other entities in connection with their financings, uses interest rate contracts which are classified as held for trading purposes. Interest rate contracts are recorded on trade date at fair value. Changes in fair value are recorded as a component of other income. The fair value of interest rate swaps is determined through the use of valuation models. The portion of the interest rate swap's initial fair value that reflects credit considerations, ongoing servicing, and transaction hedging costs is recognized over the life of the interest rate swap as an adjustment to other income. Interest rate swaps are recorded on a gross basis; assets and liabilities are netted by customer only when a legal right of set-off exists. INCOME TAXES: Pursuant to a tax-sharing agreement, the Company is included in AMBAC 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 the Company to AMBAC Inc.'s consolidated Federal income tax liability, computed substantially as if the Company 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. The Company files its own state income tax returns. Income taxes are accounted for under Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("Statement 109"). In accordance with Statement 109, 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. The Internal Revenue Code permits municipal bond insurance companies to deduct from taxable income, subject to certain limitations, the amounts added to the statutory mandatory contingency reserve during the year. The deduction taken is allowed only to the extent that U.S. Treasury noninterest-bearing Tax and Loss bonds are purchased in an amount equal to the tax benefit attributable to such deductions. The amounts deducted must be included in taxable income when the contingency reserve is released, at which time the Company will redeem the Tax and Loss bonds to satisfy the additional tax liability. Purchases of Tax and Loss bonds are recorded as payments of Federal income taxes and are not reflected in the Company's current tax provision. POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS: AMBAC Inc., 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. The Company 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. 8 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) 3 INVESTMENTS The amortized cost and estimated fair value of investments in debt securities at December 31, 1996 and 1995 were as follows: GROSS GROSS ESTIMATED AMORTIZED UNREALIZED UNREALIZED FAIR COST GAINS LOSSES VALUE ---------- ---------- ---------- ---------- 1996 Municipal obligations.............. $1,892,875 $ 86,984 $2,223 $1,977,636 Corporate securities............... 273,770 17,336 2,187 288,919 U.S. Government obligations........ 102,774 1,363 1,707 102,430 Mortgage- and asset-backed securities (includes U.S. Government Agency obligations).... 50,145 2,081 373 51,853 Other.............................. 95,015 -- 9 95,006 ---------- -------- ------ ---------- $2,414,579 $107,764 $6,499 $2,515,844 ========== ======== ====== ========== GROSS GROSS ESTIMATED AMORTIZED UNREALIZED UNREALIZED FAIR COST GAINS LOSSES VALUE ---------- ---------- ---------- ---------- 1995 Municipal obligations.............. $1,558,754 $ 98,090 $2,428 $1,654,416 Corporate securities............... 261,492 30,785 3,263 289,014 U.S. Government obligations........ 214,224 8,796 621 222,399 Mortgage- and asset-backed securities (includes U.S. Government Agency obligations).... 55,631 3,362 294 58,699 Other.............................. 163,953 -- -- 163,953 ---------- -------- ------ ---------- $2,254,054 $141,033 $6,606 $2,388,481 ========== ======== ====== ========== The amortized cost and estimated fair value of debt securities at December 31, 1996, by contractual maturity, were as follows: AMORTIZED ESTIMATED COST FAIR VALUE ---------- ---------- Due in one year or less.............................. $ 119,731 $ 119,838 Due after one year through five years................ 218,634 227,141 Due after five years through ten years............... 218,389 229,227 Due after ten years.................................. 1,807,680 1,887,785 ---------- ---------- 2,364,434 2,463,991 Mortgage- and asset-backed securities (includes U.S. Government Agency obligations)...................... 50,145 51,853 ---------- ---------- $2,414,579 $2,515,844 ========== ========== 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. 9 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) Net investment income from financial guarantee insurance operations comprised the following: 1996 1995 1994 -------- -------- -------- Bonds.......................................... $139,410 $127,865 $118,685 Short-term investments......................... 8,360 6,116 3,512 -------- -------- -------- Total investment income....................... 147,770 133,981 122,197 Investment expense.............................

As of December 31, 1996, the Company did not have any investment concentrated in any single repayment source (excluding obligations of the U.S. Government and its agencies) with a fair value greater than 2.0% of its stockholder's equity. As of December 31, 1996 and 1995, the Company held securities subject to agreements to resell for $4,369 and $4,120, respectively. Such securities were held as collateral by the Company. The agreements had terms of less than 30 days. Additionally, as of December 31, 1996 and 1995, investment securities with a fair value of $0 and $4,583, respectively, were pledged to futures brokers for required margin. 4 REINSURANCE In the ordinary course of business, AMBAC Indemnity cedes exposures under various reinsurance contracts primarily designed to minimize losses from large risks and to protect capital and surplus. The effect of reinsurance on premiums written and earned was as follows: YEAR ENDED DECEMBER 31, --------------------------------------------------------- 1996 1995 1994 ------------------ ------------------ ----------------- WRITTEN EARNED WRITTEN EARNED WRITTEN EARNED -------- -------- -------- -------- -------- -------- Direct.............. $243,097 $157,551 $192,277 $127,322 $188,057 $136,632 Assumed............. 6,664 3,126 2,756 1,349 4,541 1,325 Ceded...............

In the event that all or any of the reinsurers are unable to meet their obligations to AMBAC Indemnity under the existing reinsurance agreements, AMBAC Indemnity would be liable for such defaulted amounts. To minimize its exposure to significant losses from reinsurer insolvencies, AMBAC Indemnity evaluates the financial condition of its reinsurers and monitors concentrations of credit risk. There were no reinsurance receivables as of December 31, 1996 and 1995. As of December 31, 1996, prepaid reinsurance of approximately $139,629 was associated with AMBAC Indemnity's 10 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) three largest reinsurers. As of December 31, 1996, AMBAC Indemnity held letters of credit and collateral amounting to approximately $159,129 from its reinsurers to cover liabilities ceded under the aforementioned reinsurance contracts. During 1995 and 1994, AMBAC Indemnity terminated reinsurance contracts, resulting in return premiums to AMBAC Indemnity of $18,141 and $30,482, respectively, of which $15,700 and $25,891 were recorded as an increase to the unearned premium reserve in 1995 and 1994, respectively, with the remainder recognized as revenue. 5 LOSSES AND LOSS ADJUSTMENT EXPENSES AMBAC Indemnity's liability for losses and loss adjustment expenses includes case basis loss and loss adjustment expense reserves and the ACR. Following is a summary of the activity in the case basis loss and loss adjustment expense reserve and ACR accounts and the components of the liability for losses and loss adjustment expenses: 1996 1995 1994 ------- ------- ------- Case basis loss and loss adjustment expense reserves: Balance at January 1........................... $39,249 $38,892 $35,155 ------- ------- ------- Incurred related to: Current year.................................. 1,484 750 8,073 Prior years...................................

The lease agreements, which expire periodically through September 2014, 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 ------- 1997............................................................... $ 3,329 1998............................................................... 3,615 1999............................................................... 3,757 2000............................................................... 3,683 2001............................................................... 3,683 All later years.................................................... 50,645 ------- $68,712 ======= Rent expense for the aforementioned leases amounted to $3,286, $2,924 and $2,719 for the years ended December 31, 1996, 1995 and 1994, respectively. 7 INSURANCE REGULATORY RESTRICTIONS AMBAC Indemnity is subject to insurance regulatory requirements of the States of Wisconsin and New York and the other jurisdictions in which it is licensed to conduct business. AMBAC Indemnity'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 (the "Wisconsin Commissioner"). 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. AMBAC Indemnity paid cash dividends of $40,000, $40,000 and $36,000 on its common stock in 1996, 1995 and 1994, respectively. In addition, on April 30, 1996, AMBAC Indemnity, in conjunction with the sale of the AMBAC Inc.'s and AMBAC Indemnity's combined remaining holdings in HCIA common stock, delivered to AMBAC Inc. (in the form of an extraordinary dividend) its 2,378,672 shares of HCIA common stock, at fair value. The Wisconsin Commissioner approved such dividend. As a result, any dividends paid, or to be paid, by AMBAC Indemnity to AMBAC Inc. through June 30, 1997 require pre-approval from the Wisconsin Commissioner. The Wisconsin Commissioner has stated to AMBAC Indemnity management that it does not foresee any reason pre-approval of anticipated common stock dividends paid through June 30, 1997 would not be given. Anticipated common stock dividends paid thereafter and through year-end 1997 will not require such pre-approval. 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. Under the limit applicable to municipal bonds, the insured average annual debt service for a single risk, net of reinsurance and collateral, may not exceed 10% of 12 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) qualified statutory capital, which is defined as the sum of the insurer's policyholders' surplus and contingency reserves. In addition, insured principal of municipal bonds attributable to any single risk, net of reinsurance and collateral, is limited to 75% of the insurer's policyholders' surplus and contingency reserves. Additional single risk limits, which generally are more restrictive than the municipal bond single risk limit, are also specified for several other categories of insured obligations. Statutory capital and surplus was $899,023 and $862,976 at December 31, 1996 and 1995, respectively. Qualified statutory capital was $1,466,560 and $1,358,769 at December 31, 1996 and 1995, respectively. Statutory net income was $222,810, $142,541 and $116,238 for 1996, 1995 and 1994, respectively. 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 and deferred income taxes differently. 8 INCOME TAXES The total effect of income taxes on income and stockholder's equity for the years ended December 31, 1996 and 1995 was as follows: 1996 1995 -------- -------- Total income taxes charged to income................ $ 79,620 $ 43,546 -------- -------- Income taxes charged (credited) to stockholder's equity: Unrealized gain (loss) on bonds...................

The benefits are based on years of service and the employee's compensation during the last five years of employment. AMBAC Inc.'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 actuarial present value of the benefit obligations shown in the table below sets forth the plan's funded status and amounts recognized by AMBAC Inc. as of December 31, 1996 and 1995. 14 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) Actuarial present value of the benefit obligations: 1996 1995 ------- ------- Accumulated benefit obligation, including vested benefits of $6,282 and $6,049, respectively...................... $(6,979) $(6,788) ======= ======= Projected benefit obligation for service rendered to date....................................................

The expected long-term rate of return on assets was 9.25% for both 1996 and 1995. The rate of increase in future compensation levels used in determining the actuarial present value of the projected benefit obligation was 5.0% for both 1996 and 1995. Substantially all employees of AMBAC Inc. 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 covered employee's base salary, plus a matching company contribution of 50% on contributions up to 6% of base salary made by eligible employees to the plan. The total cost of the Savings Incentive Plan to AMBAC Indemnity was $1,494, $1,435 and $1,292 in 1996, 1995 and 1994, respectively. Annual Incentive Plan: AMBAC Inc. has an annual incentive plan which provides for awards to key officers and employees based upon predetermined criteria. The cost of the plan to AMBAC Indemnity for the years ended December 31, 1996, 1995 and 1994 amounted to $7,641, $7,669 and $8,531, respectively. Postretirement Health Care and Other Benefits: AMBAC Indemnity provides certain medical and life insurance benefits for retired employees and eligible dependents. All plans are contributory. None of the plans is currently funded. 15 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) Postretirement benefits expense was $200, $168 and $176 in 1996, 1995 and 1994, respectively. The unfunded accumulated postretirement benefit obligation was $1,526 and the accrued postretirement liability was $1,524 as of December 31, 1996. The assumed weighted average health care cost trend rates range from 8.5% in 1996, decreasing ratably to 5.5% in 2001, and remaining at that level thereafter. Increasing the assumed health care cost trend rate by one percentage point in each future year would increase the accumulated postretirement benefit obligation at December 31, 1996 by $194 and the 1996 benefit expense by $40. The weighted average discount rate used to measure the accumulated postretirement benefit obligation and 1996 expense was 7.50%. 10 INSURANCE IN FORCE The par amount of bonds insured by AMBAC Indemnity, net of reinsurance, was $131,497,000 and $110,997,000 at December 31, 1996 and 1995, respectively. As of December 31, 1996 and 1995, AMBAC Indemnity's insured portfolio was diversified by type of insured bond as shown in the following table: NET PAR AMOUNT OUTSTANDING --------------------------- 1996 1995 ------------- ------------- (DOLLARS IN MILLIONS) Municipal finance: General obligation............................. $ 31,863 $ 30,546 Lease and Tax-backed revenue................... 25,366 18,780 Utility revenue................................ 22,780 21,053 Health care revenue............................ 13,521 12,553 Transportation revenue......................... 6,891 6,293 Investor-Owned utilities....................... 5,551 4,497 Higher education............................... 4,745 3,973 Housing revenue................................ 4,497 3,577 Student loans.................................. 3,439 3,769 Other.......................................... 484 483 ------------- ------------- Total Municipal Finance...................... 119,137 105,524 ------------- ------------- Structured finance: Domestic: Mortgage-backed and home equity............... 5,263 1,901 Asset-backed.................................. 1,329 1,213 Other......................................... 1,440 124 ------------- ------------- Total Domestic Structured Finance............ 8,032 3,238 ------------- ------------- International: Asset-backed.................................. 2,530 1,382 Other......................................... 1,798 853 ------------- ------------- Total International Structured Finance....... 4,328 2,235 ------------- ------------- Total Structured finance.................... 12,360 5,473 ------------- ------------- $ 131,497 $ 110,997 ============= ============= 16 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) As of December 31, 1996, California was the state with the highest aggregate net par amount in force, accounting for 15.6% of the total, and the highest single insured risk represented 0.6% of aggregate net par amount outstanding. AMBAC Indemnity's direct insurance in force (principal and interest) was $268,870,000 and $235,118,000 at December 31, 1996 and 1995, respectively. Net insurance in force (after giving effect to reinsurance) was $227,235,000 and $199,078,000 as of December 31, 1996 and 1995, respectively. 11 FINANCIAL INSTRUMENTS HELD FOR PURPOSES OTHER THAN TRADING Financial instruments with off-balance-sheet risk: In the normal course of business, the Company becomes a party to various financial transactions to reduce its exposure to fluctuations in interest rates. These financial instruments include interest rate swaps, exchange traded interest rate futures contracts and purchased interest rate options. The notional amounts of the Company's off-balance-sheet financial instruments which are held for purposes other than trading were as follows: AS OF DECEMBER 31, ------------------ 1996 1995 ------------------ Interest rate futures contracts........................ $ -- $ 44,500 Interest rate swap..................................... -- 20,000 Notional principal amounts are often used to express the volume of these transactions and do not reflect the extent to which positions may offset one another. These amounts do not represent the much smaller amounts potentially subject to risk. Fair values of financial instruments held for purposes other than trading: The following fair value amounts were determined by the Company using independent market information when available, and appropriate valuation methodologies 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 the Company 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 bonds are based on quoted market prices or dealer quotes. Short-term investments and cash: The fair values of short-term investments and cash are assumed to equal 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 in affiliate: At December 31, 1995, the fair value of the Company's investment in HCIA was based on the quoted market price of HCIA common stock. 17 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) Interest rate contracts: Fair values of off-balance-sheet interest rate contracts (futures, swaps and interest rate options) are based on quoted market and dealer prices, current settlement values, or pricing models. Liability for net financial guarantees written: The fair value of the liability for those financial guarantees written related to new issue and secondary market exposures 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. Certain other financial guarantee insurance policies have been written on an installment basis, where the future premiums to be received by the Company are determined based on the outstanding exposure at the time the premiums are due. The fair value of AMBAC Indemnity's liability under its installment premium policies is measured using the present value of estimated future installment premiums, less an assumed ceding commission. The estimate of the amounts and timing of the future installment premiums is based on contractual premium rates, debt service schedules and expected run-off scenarios. This measure is used as an estimate of the cost to reinsure AMBAC Indemnity's liability under these policies. The carrying amount and estimated fair value of these financial instruments are presented below: AS OF DECEMBER 31, ----------------------------------------------- 1996 1995 ----------------------- ----------------------- CARRYING ESTIMATED FAIR CARRYING ESTIMATED FAIR AMOUNT VALUE AMOUNT VALUE -------- -------------- -------- -------------- (DOLLARS IN MILLIONS) Financial assets: Investments................... $2,425 $2,425 $2,225 $2,225 Short-term investments........ 91 91 164 164 Cash.......................... 5 5 7 7 Securities purchased under agreements to resell......... 4 4 4 4 Investment in affiliate....... -- -- 26 111 Unrecognized financial instruments: Interest rate futures contracts.................... -- -- -- -- Interest rate swap............ -- -- -- -- Liability for financial guarantees written: Direct....................... -- 719 -- 655 Net of reinsurance........... -- 596 -- 543 Net installment premiums..... -- 114 -- 80 12 FINANCIAL INSTRUMENTS HELD FOR TRADING PURPOSES The Company, through its affiliate AFS, is a provider of interest rate swaps to states, municipalities, municipal authorities and other entities, including its affiliates, AMBAC Capital Management, Inc. ("ACMI") and AMBAC Investments Inc. ("AII"), in connection with their financings. The Company manages its interest rate swap business with the goal of being market neutral to changes in overall interest rates, while retaining basis risk, the relationship between changes in floating rate tax-exempt and floating rate taxable interest rates. If actual or projected floating rate tax-exempt interest rates rise in relation to floating rate taxable interest rates, the Company will experience an unrealized mark-to-market loss. Conversely, if actual or projected floating rate tax-exempt interest rates decline in relation to floating rate taxable interest rates, the Company will experience an unrealized mark-to-market gain. 18 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) In the ordinary course of business, the Company manages a variety of risks, principally credit, market, liquidity, operational, and legal. These risks are identified, measured and monitored through a variety of control mechanisms, which are in place at different levels throughout the organization. Credit risk relates to the ability of counterparties to perform according to the terms of their contractual commitments. Credit risk is calculated based on the current replacement cost or fair value of the Company's financial instruments. The Company executes these transactions with a diverse base of counterparties in order to minimize concentrations of credit risk. Various procedures and controls are in place to monitor the credit risk of interest rate swaps. These include the initial credit approval process, the establishment of credit limits, management approvals, and a process that ensures the continuous monitoring of credit exposure. Market risk relates to the impact of price changes on future earnings. This risk is a consequence of the Company's market-making activities in the municipal interest rate swap market. The principal market risk is basis risk, the relationship between changes in floating rate tax-exempt and floating rate taxable interest rates. Since the third quarter of 1995, all municipal interest rate swaps transacted contain provisions which are designed to protect the Company against certain forms of tax reform, thus mitigating its basis risk. An independent risk management group monitors trading risk limits and, together with senior management, is involved in the application of risk measurement methodologies. The estimation of potential losses arising from adverse changes in market relationships, known as "value-at-risk," is a key element in managing market risk. The Company has developed a value-at-risk methodology to estimate potential losses over a specified holding period and based on certain probabilistic assessments. The Company estimates value at risk utilizing historical short- and long-term interest rate volatilities and the relationship between changes in tax-exempt and taxable interest rates calculated on a consistent daily basis. For the years ended December 31, 1996 and 1995, the Company's value-at-risk, calculated at a ninety-nine percent confidence level, averaged approximately $1,389 and $1,358, respectively. The Company's value-at-risk ranged from a high of $2,585 to a low of $1,096 in 1996 and from a high of $2,131 to a low of $687 in 1995. Since no single measure can capture all dimensions of market risk, the Company bolsters its value-at-risk methodology by performing daily analyses of parallel and non- parallel shifts in yield curves and stress test scenarios which measure the potential impact of market conditions, however improbable, which might cause abnormal volatility swings or disruptions of market relationships. Liquidity risk relates to the possible inability to satisfy contractual obligations when due. This risk is present in swaps and in futures contracts used to hedge swaps. The Company manages liquidity risk by maintaining cash and cash equivalents, closely matching the dates swap payments are made and received, and limiting the amount of risk hedged by futures contracts. Operational risk relates to the potential for loss caused by a breakdown in information, communication and settlement systems. The Company mitigates operational risk by maintaining a comprehensive system of internal controls. This includes the establishment of systems and procedures to monitor transactions and positions, documentation and confirmation of transactions, and ensuring compliance with regulations. Legal risk relates to the uncertainty of the enforceability, through legal or judicial processes, of the obligations of the Company's counterparties, including contractual provisions intended to reduce credit exposure by providing for the offsetting or netting of mutual obligations. The Company seeks to remove or minimize such uncertainties through continuous consultation with internal and external legal advisers to analyze and understand the nature of legal risk, to improve documentation and to strengthen transaction structure. 19 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) The following table summarizes information about the Company's financial instruments held for trading purposes as of December 31, 1996 and 1995: AVERAGE NET FAIR VALUE NET CARRYING NET ESTIMATED ------------------------- NOTIONAL AMOUNT FAIR VALUE ASSETS LIABILITIES AMOUNT ------------ ------------- ----------- ------------- ---------- 1996: Interest rate swaps..... $12,341 $12,341 $ 48,734 $ 41,445 $2,856,600 Interest rate futures contracts.............. -- -- -- -- 484,500 1995: Interest rate swaps..... $ 5,207 $ 5,207 $ 17,714 $ 16,667 $2,152,400 Interest rate futures contracts.............. -- -- -- -- 569,800 The aggregate amount of net trading income recognized from financial instruments held for trading purposes was $10,799, $2,602 and $3,051 for 1996, 1995 and 1994, respectively. Average net fair values were calculated based on average daily net fair values. The gross replacement cost of the Company's financial instruments held for trading purposes is the positive fair value of all transactions with a counterparty, excluding the effects of netting or collateral arrangements and was approximately $47,000 and $62,000 as of December 31, 1996 and 1995, respectively. Net estimated fair value, after netting and collateral arrangements, more accurately portrays the credit risk associated with the Company's financial instruments held for trading purposes. Notional principal amounts are often used to express the volume of these transactions and do not reflect the extent to which positions may offset one another. These amounts do not represent the much smaller amounts potentially subject to risk. 13 LINES OF CREDIT AMBAC Inc. and AMBAC Indemnity maintain a three-year revolving credit facility with two major international banks, as co-agents, for $100,000. As of December 31, 1996 and 1995, no amounts were outstanding under this credit facility, which expires in July 1998. AMBAC Indemnity has an agreement with another major group of AAA/Aaa-rated international banks for a $350,000 credit facility, expiring in 2003. This facility is a seven-year stand-by irrevocable limited recourse line of credit, which was increased from $300,000 to $350,000 and extended for an additional year in December 1996. The line will provide liquidity to AMBAC Indemnity in the event claims from municipal obligations exceed specified levels. Repayment of any amounts drawn under the line will be limited primarily to the amount of any recoveries of losses related to policy obligations. As of December 31, 1996 and 1995, no amounts were outstanding under this line. 14 RELATED PARTY TRANSACTIONS During 1996 and 1995, AMBAC Indemnity guaranteed the timely payment of principal and interest on obligations under municipal investment contracts and municipal investment repurchase agreements issued by its affiliates. As of December 31, 1996 and 1995, the aggregate amount of municipal investment contracts and municipal investment repurchase contracts insured was $2,744,283 and $2,240,959, respectively, including accrued interest. These insurance policies are collateralized by investment securities, accrued interest, securities purchased 20 AMBAC INDEMNITY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS) under agreements to resell and cash and cash equivalents, which as of December 31, 1996 and 1995 had a fair value of $2,775,250 and $2,299,687, respectively, in the aggregate. During 1996 and 1995, AMBAC Indemnity recorded gross premiums written of $2,553 and $1,707, and net premiums earned of $1,668 and $1,764, respectively, related to these contracts. During 1996 and 1995, several interest rate swap transactions were executed between AFS and its affiliates (other than AMBAC Indemnity). As of December 31, 1996 and 1995, these contracts had an outstanding notional amount of approximately $515,000 and $359,000, respectively. As of December 31, 1996 and 1995, AFS recorded a positive fair value of $3,503 and $6,539, respectively, related to these transactions. 21
