("AFGI"), headquartered in New York City, is a holding company whose subsidiaries provide financial guarantee insurance and financial management services to clients in both the public and private sectors in the United States and abroad. The following paragraphs describe the consolidated results of operations of AFGI and its subsidiaries (collectively referred to as the "Company") for 1998, 1997 and 1996, and its financial condition as of December 31, 1998 and 1997. These results are presented for the Company's two reportable segments: Financial Guarantee Insurance and Financial Management Services. This discussion should be read in conjunction with the consolidated financial statements included elsewhere in this report. In this Annual Report, we may make statements about our future results that are considered "forward-looking statements" under the Private Securities Litigation Reform Act of 1995. These statements are based on our current expectations and the current economic environment. We caution you that these statements are not guarantees of future performance. They involve a number of risks and uncertainties that are difficult to predict. Our actual results could differ materially from those expressed or implied in the forward-looking statements. Among the factors that could cause actual results to differ materially are: (1) changes in the economic, credit, or interest rate environment in the United States and abroad; (2) the level of activity within the national and worldwide debt markets; (3) competitive conditions and pricing levels; (4) legislative and regulatory developments; (5) changes in tax laws; and (6) other risks and uncertainties that have not been identified at this time. We undertake no obligation to publicly correct or update any forward-looking statement if we later become aware that it is not likely to be achieved. RESULTS OF OPERATIONS CONSOLIDATED NET INCOME. The Company's net income in 1998 was $254.0 million or $3.56 per diluted share, an increase of 14% from $223.0 million or $3.13 per diluted share in 1997. This increase was primarily attributable to the growth in both Financial Guarantee Insurance and Financial Management Services revenues, partially offset by lower net realized gains and higher net realized losses in the Financial Guarantee Insurance segment and the Financial Management Services segment, respectively, in 1998. The Company's net income in 1997 decreased 19% from $276.3 million or $3.91 per diluted share in 1996. This decrease was primarily the result of a net realized gain in 1996 of $155.6 million (which had a net income per diluted share effect of $1.42) from the Company's sale of its former subsidiary, HCIA Inc. ("HCIA"). Excluding the effect of this one-time gain, 1997 net income increased 27% over 1996 primarily due to higher net income in the Financial Guarantee Insurance segment, partially offset by lower net income in the Financial Management Services segment. FINANCIAL GUARANTEE INSURANCE The Company provides financial guarantee insurance through its principal operating subsidiary, Ambac Assurance Corporation ("Ambac Assurance"), which is a leading insurer of municipal and structured finance obligations both in the United States and abroad. In December 1997, Ambac Assurance acquired Connie Lee Holdings, Inc. and its triple-A rated financial guarantee insurance subsidiary, Connie Lee Insurance Company ("Connie Lee"). No new business was written by Connie Lee in 1998. GROSS PAR VALUE WRITTEN. Ambac Assurance insured $61.5 billion of par value bonds during 1998, an increase of 35% from $45.5 billion in 1997. Par value [PHOTO] 23 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS written in 1997 represented an increase of 27% from $35.7 billion in 1996. Par value written in 1998 comprised $33.9 billion from the insurance of domestic municipal bond obligations, $22.6 billion from domestic structured finance obligations and $5.0 billion from international obligations, versus $29.4 billion, $12.9 billion and $3.2 billion, respectively, in 1997 and $26.8 billion, $6.4 billion and $2.5 billion, respectively, in 1996. The 1998 increase in insured domestic municipal bond obligations resulted primarily from a 30% increase in market issuance and an increase in insured penetration, partially offset by lower market share. The 1998 increase in insured domestic structured finance obligations was attributable to increased market issuance, higher market penetration and a higher market share in the home equity loan and mortgage- backed sectors, as well as increased market presence in the commercial asset- backed sector. The 1998 increase in insured international obligations resulted from greater acceptance of financial guarantee insurance, primarily in Europe, Japan and Latin America. Management believes, based on growth experienced in the last few years, that in the foreseeable future, domestic structured finance and international markets will grow more rapidly than the domestic municipal market. Domestic structured finance and international insured par may see large quarterly variances, primarily due to the developmental nature of these markets. Ambac Assurance serves clients in international markets through its wholly-owned subsidiary Ambac Insurance UK Limited and through an arrangement with MBIA Insurance Company ("MBIA") to participate in MBIA.AMBAC International, an unincorporated joint venture with MBIA (the "JV Arrangement"). See Note 5 of Notes to Consolidated Financial Statements for further discussion about the JV Arrangement. GROSS PREMIUMS WRITTEN. Gross premiums written in 1998 were $361.0 million, an increase of 26% from $286.2 million in 1997. This increase was primarily driven by a 28% increase in new issue municipal finance premiums and a 46% increase in international premiums. Gross premiums written in 1997 increased 16% from $247.2 million in 1996. This increase was primarily due to higher new issue municipal finance premiums written. The following table sets forth the amounts of gross premiums written and related gross par written by type: =========================================================================================================================== (Dollars in millions) 1998 1997 1996 - --------------------------------------------------------------------------------------------------------------------------- Gross Gross Gross Gross Gross Gross Premiums Par Premiums Par Premiums Par Written Written Written Written Written Written - --------------------------------------------------------------------------------------------------------------------------- Domestic: Municipal finance: Up-front: New issue $228.2 $29,616 $178.9 $25,889 $182.9 $23,735 Secondary market 14.6 1,400 19.6 1,530 20.4 1,362 - --------------------------------------------------------------------------------------------------------------------------- Sub-total up-front 242.8 31,016 198.5 27,419 203.3 25,097 Installment 17.7 2,899 13.5 2,024 13.0 1,641 - --------------------------------------------------------------------------------------------------------------------------- Total municipal finance 260.5 33,915 212.0 29,443 216.3 26,738 - --------------------------------------------------------------------------------------------------------------------------- Structured finance: Up-front 1.4 1,985 11.1 922 1.2 156 Installment 35.7 20,581 19.6 11,952 8.8 6,255 - --------------------------------------------------------------------------------------------------------------------------- Total structured finance 37.1 22,566 30.7 12,874 10.0 6,411 - --------------------------------------------------------------------------------------------------------------------------- Total domestic 297.6 56,481 242.7 42,317 226.3 33,149 - --------------------------------------------------------------------------------------------------------------------------- International: Up-front 52.8 2,463 37.6 1,566 18.0 690 Installment 10.6 2,553 5.9 1,575 2.9 1,839 - --------------------------------------------------------------------------------------------------------------------------- Total international 63.4 5,016 43.5 3,141 20.9 2,529 - --------------------------------------------------------------------------------------------------------------------------- Total $361.0 $61,497 $286.2 $45,458 $247.2 $35,678 =========================================================================================================================== Total up-front $297.0 $35,464 $247.2 $29,907 $222.5 $25,943 Total installment 64.0 26,033 39.0 15,551 24.7 9,735 - --------------------------------------------------------------------------------------------------------------------------- Total $361.0 $61,497 $286.2 $45,458 $247.2 $35,678 =========================================================================================================================== ADJUSTED GROSS PREMIUMS. (1) While the majority of Ambac Assurance's premiums written are collected up front at policy issuance, a growing portion of premiums are collected on an installment basis. Adjusted gross premiums written, which are defined as up-front premiums written plus the present value of estimated future installment premiums written in the period, were $458.0 million in 1998, up 39% from $329.3 million in 1997. The increase in 1998 was primarily due to increased up-front premiums written in all markets, combined with the increase in the present value of international installment policies. Adjusted gross premiums written in 1997 increased 15% from $286.8 million in 1996. The present value of estimated future installment premiums written in 1998 was $173.4 million, an increase of 94% from $89.3 million in 1997. The present value of estimated future installment premiums written in 1997 increased 27% from $70.3 million in 1996. The aggregate net present value of estimated future installment premiums was $308.4 million, $210.8 million, and $157.7 million as of December 31, 1998, 1997 and 1996, respectively. 24 CEDED PREMIUMS WRITTEN. Ceded premiums written in 1998 were $49.6 million, up 53% from $32.5 million in 1997. The increase in ceded premiums written is primarily due to the cession of $11.6 million of premiums related to Connie Lee's insured portfolio. In 1997, Ambac Assurance began using only facultative reinsurance to reduce its risk and manage its insurance portfolio. Ceded premiums written in 1996 were $37.8 million. The 14% decrease from 1996 to 1997 is primarily due to the non-renewal of automatic treaty reinsurance, partially offset by higher ceded premiums for international business pursuant to the JV Arrangement. Ceded premiums written were 14%, 11%, and 15% of gross premiums written in 1998, 1997 and 1996, respectively. NET PREMIUMS EARNED. Net premiums earned during 1998 were $212.7 million, an increase of 38% from $154.0 million in 1997. This increase was primarily the result of higher premiums earned from the growth of the book of business and increased premiums earned from refundings, calls and other accelerations (collectively referred to as "refundings") during the year. When an issue insured by Ambac Assurance has been refunded or called, the remaining unearned premium (net of refunding credits, if any) is generally earned at that time. Refunding levels vary depending upon a number of conditions, primarily the relationship between current interest rates and interest rates on outstanding debt. Net premiums earned in 1998 included $46.9 million (net income per diluted share effect of $0.37) from refundings. Net premiums earned in 1997 included $28.0 million (net income per diluted share effect of $0.22) from refundings. Excluding the effect of accelerated earnings related to refundings, net premiums earned in 1998 were $165.8 million, an increase of 32% from $126.0 million in 1997. Net premiums earned during 1997 increased 13% from $136.6 million in 1996. This increase was primarily the result of higher premiums earned from the growth of the book of business during the year, partially offset by a decline in premiums earned from refundings in 1997. Net premiums earned in 1996 included $31.3 million (net income per diluted share effect of $0.25) from refundings. Excluding the effect of accelerated earnings related to refundings, net premiums earned in 1997 increased 20% from $105.3 million in 1996. NET INVESTMENT INCOME. Net investment income in 1998 was $186.2 million, an increase of 17% from $159.7 million in 1997. This increase was primarily attributable to the growth of the investment portfolio from ongoing operations and the net increase in the investment portfolio from the acquisition of Connie Lee, partially offset by lower yields. Investments in tax-exempt securities amounted to 74% of the total market value of the portfolio as of December 31, 1998, versus 75% and 79% as of December 31, 1997 and 1996, respectively. The average pre-tax yield-to-maturity on the investment portfolio was 6.17% as of December 31, 1998 compared with 6.40% and 6.47% for December 31, 1997 and 1996, respectively. Net investment income in 1997 increased 10% from $144.9 million in 1996. This increase was primarily attributable to the growth of the investment portfolio, partially offset by lower yields. NET REALIZED GAINS (LOSSES). Net realized gains in 1998 were $3.7 million, compared to $21.1 million in net realized gains in 1997. The 1998 and 1997 net realized gains were generated as a result of the ongoing management of the investment portfolio. Net realized losses of $20.5 million in 1996 were realized for tax planning purposes to partially offset the realized gain from the sale of HCIA. LOSSES AND LOSS ADJUSTMENT EXPENSES. Losses and loss adjustment expenses in 1998 were $6.0 million, versus $2.9 million in 1997 and $3.8 million in 1996. Losses and loss adjustment expenses are based upon estimates of the ultimate aggregate losses inherent in the insured portfolio. The liability for losses and loss adjustment expenses consists of the active credit reserve ("ACR"), which represents an estimate of unidentified losses, and case basis loss reserves for obligations in monetary default, or, in the judgement of management, for which default is imminent. The Company regularly reviews its outstanding obligations to determine an appropriate reserve for losses and loss adjustment expenses. The following table summarizes the Company's loss reserves split between case basis loss reserves and ACR at December 31, 1998 and 1997: =========================================================================== (Dollars in millions) 1998 1997 - --------------------------------------------------------------------------- Net loss and loss adjustment expense reserves: Case basis* $ 33.9 $50.9 ACR 78.2 48.2 - --------------------------------------------------------------------------- Total $112.1 $99.1 =========================================================================== * After netting reinsurance recoverable amounting to $3.6 million and $4.2 million in 1998 and 1997, respectively. Paid losses, net of salvage received, were ($7.0) million, $2.5 million and $9.6 million in 1998, 1997 and 1996, respectively. UNDERWRITING AND OPERATING EXPENSES. Underwriting and operating expenses were $46.7 million in 1998, an increase of 15% from $40.7 million in 1997. Underwriting and operating expenses in 1997 increased 9% from $37.2 million in 1996. Underwriting and operating expenses consist of gross underwriting and operating expenses, less the deferral to future periods of expenses and reinsurance commissions related to the acquisition of new insurance contracts, plus the amortization of previously deferred expenses and reinsurance commissions. During 1998, gross underwriting and operating expenses were $67.8 million, an increase of 15% from $59.2 million in 1997. During 1997, gross underwriting and operating expenses increased 5% from $56.4 million in 1996. The increase in gross underwriting and operating expenses in both 1998 and 1997 reflects the overall increased business activity in those years. Underwriting and operating expenses deferred were $38.2 million, 25 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS $32.8 million, and $32.3 million in 1998, 1997 and 1996, respectively. The amortization of previously deferred expenses and reinsurance commissions was $18.2 million, $14.2 million, and $12.5 million in 1998, 1997 and 1996, respectively. FINANCIAL MANAGEMENT SERVICES Through its financial management services subsidiaries, the Company provides investment agreements, interest rate swaps, investment advisory and cash management services, principally to states, municipalities and their authorities, school districts, and hospitals and health organizations. In the fourth quarter of 1998, the Company discontinued development of electronic commerce applications for the municipal marketplace. This effort had been underway as a pilot operation through a subsidiary, Ambac Connect, Inc. ("Ambac Connect"). The decision resulted in an after-tax charge of $9.5 million, or $0.13 in net income per diluted share. This charge did not affect operating or core earnings.(2) Revenues in 1998 were $49.5 million (excludes $17.1 million in net realized losses), versus $35.2 million (excludes $0.6 million in net realized losses) in 1997. This increase is primarily due to higher revenues on interest rate swaps and investment agreements primarily due to increased volume. In 1998, realized gains on fixed-income securities in the investment agreement business of $10.1 million were offset by a realized loss of $11.5 million, representing the write-off of the Company's entire investment in Ambac Connect (this write-off is included in the $9.5 million after-tax charge discussed above), and a $15.7 million loss in a trading position. This trading position, which represented a small portion of the Company's assets, contained high quality municipal bonds hedged with treasury futures. The loss was due to a change in the relationship between municipal and treasury interest rates. This trading position was closed during the fourth quarter of 1998. Revenues in 1997 reflected a 60% increase from $22.0 million (excludes $0.4 million in net realized gains) in 1996. The increase was primarily due to revenues of Cadre Financial Services, Inc. ("Cadre"), acquired at the end of 1996, which provides investment advisory and cash management services primarily to school districts, and higher revenues from investment agreements, due to higher volume. Expenses in 1998 were $32.5 million (excluding a $3.0 million restructuring charge for Ambac Connect), versus $24.5 million (excluding a $3.5 million restructuring charge for consolidating certain operations in New York) in 1997. This increase results from higher compensation expenses in the investment agreement and swap businesses, as well as increased expenditures to develop the money management and electronic commerce businesses. Expenses in 1997 increased 104% (excluding the $3.5 million 1997 restructuring charge for consolidating certain operations in New York) from $12.0 million in 1996. This increase reflects expenses for Cadre and start-up expenses for Ambac Connect. CORPORATE ITEMS INTEREST EXPENSE. Interest expense in 1998 was $32.8 million, an increase of 54% from $21.3 million in 1997. The increase is attributable to AFGI's issuance of $200 million in debentures in April 1998. Interest expense in 1996 was $20.9 million. OTHER INCOME. Other income includes investment income of AFGI. Other income increased to $13.7 million in 1998 from $7.2 million in 1997, primarily due to higher investment income generated from investing the proceeds of AFGI's $200 million in debentures. Other income decreased in 1997 from $7.9 million in 1996. OTHER NET REALIZED GAINS. The other net realized gain in 1996 resulted primarily from the sale of the Company's remaining holdings in HCIA in a secondary public offering yielding net proceeds of $202.6 million. The sale resulted in a net realized gain of $155.6 million pre-tax, $100.6 million after-tax (net income per diluted share effect of $1.42). OTHER EXPENSES. Other expenses include the operating expenses of AFGI. Other expenses were $7.1 million in 1998, $2.9 million in 1997, and $3.5 million in 1996. Other expenses were higher in 1998 compared to 1997 primarily due to increased compensation costs. INCOME TAXES. Income taxes for 1998 were at an effective rate of 22.8%, compared to 22.0% and 26.4% for 1997 and 1996, respectively. The 1996 effective tax rate was higher compared to 1998 and 1997 due to the realized gain of the sale of HCIA as discussed above. SUPPLEMENTAL ANALYTICAL FINANCIAL DATA CORE EARNINGS. (2) In 1998 core earnings were $236.5 million, an increase of 21% from $195.8 million in 1997. This increase was primarily the result of continued higher premiums earned from the growth in the insurance book of business and higher net investment income from insurance operations, as well as higher revenues from the investment agreement and swap businesses in the Financial Management Services segment. In 1997 core earnings increased 15% from $170.5 million in 1996. The increase was primarily the result of continued higher premiums earned from the growth in the insurance book of business and higher net investment income from insurance operations. Core earnings, which the Company reports as analytical data, exclude the effect on consolidated net income from net realized gains and losses, net insurance premiums earned from refundings and certain non-recurring items. OPERATING EARNINGS. (2) Operating earnings in 1998 were $263.3 million, an increase of 24% from $211.8 million in 1997. Operating earnings in 1997 increased 12% from $188.3 million in 1996. The Company defines operating earnings as net income, less the effect of net realized gains and losses and certain non-recurring items. Following is a table reconciling net income computed in accordance with U.S. Generally Accepted Accounting 26 Principles ("GAAP") to operating earnings and core earnings for the years ended December 31, 1998, 1997 and 1996: =========================================================================== (Dollars in Millions) 1998 1997 1996 - --------------------------------------------------------------------------- Net income $254.0 $223.0 $276.3 Net realized losses (gains), after tax 7.1 (13.3) (88.0) Non-recurring item, after tax 2.2 2.1 - - --------------------------------------------------------------------------- Operating earnings 263.3 211.8 188.3 Premiums earned from refundings, after tax (26.8) (16.0) (17.8) - --------------------------------------------------------------------------- Core earnings $236.5 $195.8 $170.5 =========================================================================== LIQUIDITY AND CAPITAL RESOURCES AFGI LIQUIDITY. AFGI's liquidity, both on a short-term basis (for the next twelve months) and a long-term basis (beyond the next twelve months), is largely dependent upon: (i) Ambac Assurance's ability to pay dividends or make payments to AFGI; and (ii) external financings. Pursuant to Wisconsin insurance laws, Ambac Assurance may declare dividends, provided that, after giving effect to the distribution, it would not violate certain statutory equity, solvency and asset tests. During 1998, Ambac Assurance paid dividends of $48.0 million on its common stock to AFGI. For further discussion, see Note 8 of Notes to Consolidated Financial Statements. AFGI's principal uses of liquidity are for the payment of its operating expenses, interest on its debt, dividends on its shares of common stock, and capital investments in its subsidiaries. Based on the amount of dividends that Ambac Assurance expects to pay during 1999 and the income it expects to receive from its investment portfolio, management believes AFGI will have sufficient liquidity to satisfy its liquidity needs over the next twelve months, including the payment of dividends on the common stock in accordance with its dividend policy. Beyond the next twelve months, Ambac Assurance's ability to declare and pay dividends to AFGI may be influenced by a variety of factors, including adverse market changes, insurance regulatory changes and changes in general economic conditions. Consequently, although management believes that AFGI will continue to have sufficient liquidity to meet its debt service and other obligations over the long term, no guarantee can be given that Ambac Assurance will be permitted to dividend amounts sufficient to pay all of AFGI's operating expenses, debt service obligations and dividends on its common stock. On April 1, 1998, AFGI issued $200.0 million in principal amount of its 7.08% debentures due on March 31, 2098. AFGI may not redeem the debentures prior to March 31, 2003. On or after March 31, 2003, AFGI may redeem the debentures, in whole at any time or in part from time to time, at 100% of their principal amount, plus accrued interest to the date of redemption. Use of the net proceeds received from the sale of the debentures will be for general corporate purposes, which include additions to working capital of subsidiaries, acquisitions, and repurchases of common stock. AMBAC ASSURANCE LIQUIDITY. The principal uses of Ambac Assurance's liquidity are the payment of operating expenses, reinsurance premiums, income taxes, and dividends to AFGI. Management believes that Ambac Assurance's operating liquidity needs can be funded exclusively from its operating cash flow. The principal sources of Ambac Assurance's liquidity are gross premiums written, scheduled investment maturities and net investment income. The majority of premiums for Ambac Assurance's financial guarantee insurance policies are payable in full at the outset of the term of the policy, even though premiums are earned over the life of such policies for financial accounting purposes. FINANCIAL MANAGEMENT SERVICES LIQUIDITY. The principal uses of liquidity by Financial Management Services subsidiaries are the payment of investment agreement obligations pursuant to defined terms, net obligations under interest rate swaps and related hedges, operating expenses, and income taxes. Management believes that its Financial Management Services liquidity needs can be funded primarily from its operating cash flow and the maturity of its invested assets. The principal sources of this segment's liquidity are proceeds from issuance of investment agreements, net investment income, maturities of securities from its investment portfolio which are invested with the objective of matching the duration of its obligations under the investment agreements, net receipts from interest rate swaps and related hedges, and fees for investment management services. Additionally, from time to time, liquidity needs are satisfied by short-term inter-company loans from AFGI. The investment objectives with respect to investment agreements are to achieve the highest after-tax total return, subject to a minimum average quality rating of Aa/AA on invested assets, and to maintain cash flow matching of invested assets to funded liabilities to minimize interest rate and liquidity exposure. A portion of Financial Management Services assets are maintained in short-term investments and repurchase agreements in order to meet unexpected liquidity needs. CREDIT FACILITIES. AFGI and Ambac Assurance have a revolving credit facility with three major international banks for $150 million, which expires in August 1999 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, 1998 and 1997, no amounts were outstanding under this credit facility. Ambac Assurance maintains third party capital support in the form of a seven-year irrevocable limited recourse credit facility from a group of highly-rated international banks. This credit facility provides liquidity to Ambac Assurance in the event claims from municipal obligations in its covered portfolio exceed specified levels. Repayment of amounts drawn under the credit facility are limited primarily to the amount of any recoveries of losses related to policy obligations. During 1998, total third party capital support was increased from $500 million to $555 million and its expiration reset to 27 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS December 2, 2005. As of December 31, 1998 and 1997, no amounts were outstanding under this facility. STOCK REPURCHASE PROGRAM. The Board of Directors of AFGI has authorized the establishment of a stock repurchase program that permits the purchase of up to 6,000,000 shares of AFGI's common stock. During 1998, AFGI acquired approximately 976,000 treasury shares for an aggregate amount of $52.7 million. Since inception of the Stock Repurchase Program, AFGI has acquired approximately 4,248,000 shares for an aggregate amount of $142.7 million. ADJUSTED BOOK VALUE.(3) Adjusted Book Value ("ABV") per share increased 15% to $41.98 at December 31, 1998 from $36.59 at December 31, 1997. The following table reconciles book value per share to ABV per share as of December 31, 1998 and 1997: ============================================================================= 1998 1997 - ----------------------------------------------------------------------------- Book value per share $29.97 $26.77 After-tax value of: Net unearned premium reserve 10.17 9.25 Deferred acquisition costs (1.12) (0.99) Present value of installment premiums 2.86 1.96 Unrealized gain (loss) on investment agreements 0.10 (0.40) - ----------------------------------------------------------------------------- Adjusted book value per share $41.98 $36.59 ============================================================================= BALANCE SHEET. Total assets as of December 31, 1998 were $11.21 billion, an increase of 35% over $8.29 billion at December 31, 1997. The increase was primarily due to the increased volume in investment agreements and positive net cash flow from the Financial Guarantee Insurance segment. Stockholders' equity as of December 31, 1998 was $2.10 billion, an increase of 12% from $1.87 billion at year-end 1997. This increase was primarily due to net income for the year and higher net unrealized gains in the investment portfolio, partially offset by dividends to shareholders and stock option exercises. CASH FLOWS. Net cash provided by operating activities was $337.7 million, $324.5 million and $190.6 million during 1998, 1997 and 1996, respectively. These cash flows were primarily provided by the Financial Guarantee Insurance operations. Net cash provided by financing activities was $1,723.0 million, $1,564.3 million and $463.2 million during 1998, 1997 and 1996, respectively. This activity included $1,391.9 million, $1,096.5 million and $499.2 million in investment agreements issued (net of draws paid) in 1998, 1997 and 1996, respectively. The total cash provided by operating and financing activities was $2,060.7 million, $1,888.8 million and $653.8 million during 1998, 1997 and 1996, respectively. From these totals, $2,061.7 million, $1,887.3 million and $658.2 million was used in investing activities, principally net purchases of investment securities, during 1998, 1997 and 1996, respectively. MATERIAL COMMITMENTS. The Company has made no commitments for material capital expenditures within the next twelve months. RISK MANAGEMENT In the ordinary course of business, the Company, through its subsidiaries, manages a variety of risks, principally market, credit, 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. Market risk represents the potential for losses that may result from changes in the market value of a financial instrument as a result of changes in market conditions. The Company has financial instruments held for purposes other than trading and for trading purposes. The principal market risk for the Company's financial instruments held for purposes other than trading is interest rate risk. An independent market risk management group is involved in setting and monitoring risk limits and the application of risk measurement methodologies. The estimation of potential losses arising from adverse changes in market conditions is a key element in managing market risk. The Company utilizes various models and stress test scenarios to monitor and manage interest rate risk. This process includes frequent analyses of both parallel and non-parallel shifts in the yield curve. These models include estimates, made by management, which utilize current and historical market information. The valuation results from these models could differ materially from amounts that would actually be realized in the market. Financial instruments held for purposes other than trading which may be adversely affected by changes in interest rates consist primarily of investment securities, investment agreement liabilities, debentures, and related derivative contracts (primarily interest rate swaps and financial futures) used for hedging purposes. The following table summarizes the estimated change in fair value (based primarily on the valuation models discussed above) on the net balance of financial instruments held for purposes other than trading assuming immediate changes in interest rates at specified levels at December 31, 1998 and 1997: (Dollars in Millions) =============================================================================== Estimated fair value of net Change in financial instruments held Estimated change interest rates for purposes other than trading in fair value - ------------------------------------------------------------------------------- 1998: 300 basis point rise $2,172 $(757) 200 basis point rise 2,401 (529) 100 basis point rise 2,655 (275) Base Scenario 2,930 - 100 basis point decline 3,215 285 200 basis point decline 3,500 570 300 basis point decline 3,802 872 1997: 300 basis point rise $2,071 $(560) 200 basis point rise 2,264 (367) 100 basis point rise 2,489 (142) Base Scenario 2,631 - 100 basis point decline 2,801 170 200 basis point decline 2,965 334 300 basis point decline 3,136 505 =============================================================================== 28 The Company, through its subsidiary Ambac Financial Services, L.P. ("AFSLP"), is a provider of interest rate swaps to states, municipalities and their authorities and other entities in connection with their financings. AFSLP manages its business with the goal of being market neutral to changes in overall interest rates, while seeking to profit from retaining some basis risk. If actual or projected floating tax-exempt interest rates change in relation to floating taxable interest rates, the Company will experience an unrealized mark- to-market gain or loss. The AFSLP swap portfolio is considered held for trading purposes. Since late 1995, most municipal interest rate swaps transacted by AFSLP contain provisions which are designed to protect the Company against certain forms of tax reform, thus mitigating its basis risk. An independent market 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 for financial instruments held for trading purposes. 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's methodology estimates value-at-risk using a 300 day historical "look back" period. This means that changes in market values are simulated using market inputs from the past 300-days. For the years ended December 31, 1998 and 1997, the Company's value-at-risk, for financial instruments considered held for trading purposes, calculated at a ninety-nine percent confidence level, averaged approximately $1.0 million and $0.6 million, respectively. The Company's value-at-risk ranged from a high of $1.1 million to a low of $0.7 million in 1998, and from a high of $1.1 million to a low of $0.3 million in 1997. Since no single measure can capture all dimensions of market risk, the Company supplements 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 normal market conditions, which might cause abnormal volatility swings or disruptions of market relationships. Credit risk arises from the potential inability of issuers of bond obligations in Ambac Assurance's insured portfolio and other counterparties to perform on an obligation in accordance with the terms of the contract. The Company is exposed to credit risk in various capacities including as an issuer of a financial guarantee policy, as counterparty to financial contracts and as a holder of investment securities. The Company has established various procedures and controls to monitor and manage credit risk. These include the initial credit review and approval process, minimum credit rating requirements, single credit concentration limits and the continuous monitoring of credit exposures. Liquidity risk relates to the possible inability to satisfy contractual obligations when due. This risk is present in financial guarantee insurance, investment agreements, interest rate swaps and futures contracts. Ambac Assurance manages its liquidity risk by maintaining a comprehensive daily analysis of projected cash flows. Additionally, Ambac Assurance maintains a minimum level of cash and short-term investments at all times. See additional discussion in "Liquidity and Capital Resources" section. The investment agreement business manages liquidity risk by matching the effective duration of its invested assets, including hedges, with the effective duration of its investment agreement liabilities. Additionally, the Company's policy is to maintain a minimum level of cash and short-term investments equivalent to a specified percentage of its investment agreement liabilities outstanding. AFSLP maintains cash and cash equivalents, closely matching the dates swap payments are made and received, and limiting the amount of risk hedged with 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 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 that Ambac Assurance insures or obligations of the Company's counterparties, including contractual provisions intended to reduce 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. OTHER MATTERS YEAR 2000. The Company is addressing the issue of computer programs' and embedded computer chips' ability to distinguish between the year 1900 and the year 2000, commonly known as the Y2K problem ("Y2K"). The Company is assessing the risks to its businesses related to the functionality of its own computer systems and those of third parties. This is a high priority undertaking and crucial to the operation of the Company's businesses. The Company has established a Y2K Steering Committee comprised of members of senior management. The committee has full responsibility and authority to establish methodologies and budgets and to allocate necessary resources. The committee is responsible for the coordination of internal and external resources with the goal of evaluating and remediating, if necessary, critical technology systems. The Company has also contracted with an outside consultant to support its Y2K initiative. In connection with this initiative, the Company embarked on a three phase process. Phase I is an inventory analysis and impact assessment. Inventory included: 29 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (a) those information technology systems which were deemed critical to running the businesses; (b) non-information technology systems such as fire systems, elevators and the like; (c) material third parties such as electronic data interchange ("EDI") partners; (d) hardware and software vendors; and (e) business user spreadsheets. Phase II is the testing phase during which: (a) all critical systems are tested; (b) transactions are run through critical systems by applying various permutations and combinations of Y2K sensitive dates; and (c) results are reviewed independently by each business unit. In Phase III, the extent of code repair is determined and remediated. Phase I, the inventory analysis and impact assessment, is 100% complete. Phase II, the testing phase, is 100% complete for all aspects of the business except for the investment advisory and cash management services business (Cadre). Phase II is approximately 80% complete for Cadre, and is expected to be 100% complete by March 31, 1999. Phase III, code repair, is 100% complete for all aspects of the business except for Cadre. Code repair, if necessary for Cadre, is targeted for completion by March 31, 1999. The cost of identifying, testing and remediating critical systems is estimated to be approximately $1.1 million, $0.7 million of which was incurred in 1998. The Company's principal Y2K risks can be grouped into four categories. The first is the risk that the Company does not successfully ready its operations for the next century. The second is the risk of disruption of Company operations due to operational failures of third parties. The third is the risk of business interruption among obligors of Ambac-insured obligations such that the scheduled payment of debt service does not occur, thus triggering a claim under its insurance policy. The fourth is financial institution risk. These risks are further described below. COMPANY'S INTERNAL SYSTEMS RISK. The Company, like other financial institutions, is heavily dependent upon its computer systems. Y2K problems in the Company's internal systems could result in an interruption in, or failure of, certain normal business activities or operations. Such failures could adversely affect the Company's operations. THIRD PARTY RISK. Computer failure of third parties may also jeopardize Company operations, but how seriously depends on the nature and duration of such failures. Such third parties could include suppliers of telecommunications, electric power suppliers, and services provided by governmental agencies. Although the Company's inquiries are under way, the Company does not yet have the information to estimate the likelihood of significant disruptions among its suppliers. ISSUER RISK. A potential exposure to the Company is the failure by any insured issuer to make debt service payments due to an issuer's systems failure. An issuer's failure to make debt service payments due to Y2K related systems failures may result in a claim under an Ambac Assurance insurance policy. In such event, the Company would utilize its sources of liquidity to pay claims. The Company would expect full recovery of such claims. FINANCIAL INSTITUTION RISK. Financial institution risk includes trustees or paying agents on transactions insured by the Company. The Company relies on the operating systems of such trustees to identify the correct interest payment dates, calculate the correct payments and, through various payment systems, to move the funds to the bondholders. This risk is mitigated by the fact that Ambac Assurance's obligation to pay claims is related to the creditworthiness of the issuer and not the trustee. However, to minimize payment disruption and identify potential future problems, the Company has requested compliance statements from certain trustees or paying agents of its insured transactions, reviewed the appropriate publicly available disclosures and monitored the activities of the banking regulatory agencies for Y2K developments. Additionally, financial institution risk relates to custodians of securities held for its own account and the accounts of others. The procedures outlined above have been applied to such custodians as well. With respect to the Company's internal operations, preliminary findings do not give any indications that these systems will be non-compliant, management is in the process of developing contingent procedures in the event its critical systems should fail. With respect to third parties, the Company's inquiries are underway, and the Company does not expect significant disruptions among vendors, EDI partners, issuers and financial institutions. FOOTNOTES (1) Adjusted gross premiums written, which is not promulgated under GAAP, is used by management, equity analysts and investors to measure the financial results of the Company. Adjusted gross premiums written, which the Company reports as analytical data, is defined as gross up-front premiums written plus the present value of estimated future installment premiums written in the period. The definition of adjusted gross premiums written used by the Company may differ from definitions of adjusted gross premiums written used by other public holding companies of financial guarantee insurers. The definition of adjusted gross premiums written, and all current and historical figures, have been revised to better reflect the Company's international joint venture arrangement with MBIA. Under the revision, all reinsurance cessions to MBIA under the joint venture reinsurance arrangement reduce adjusted gross premiums written. Consequently, the revised adjusted gross premiums written recorded by the Company includes only the net retention on business written under the joint venture arrangement. (2) Core earnings and operating earnings are not substitutes for net income computed in accordance with GAAP, but are important measures used by management, equity analysts and investors to measure the financial results of the Company. The definition of core earnings and operating earnings used by the Company may differ from definitions of core earnings and operating earnings used by other public holding companies of financial guarantee insurers. (3) Adjusted book value ("ABV"), which is not promulgated under GAAP, is used by management, equity analysts and investors as a measurement of the Company's intrinsic value with no benefit given for ongoing business activity. Management derives ABV by beginning with stockholders' equity (book value) and adding or subtracting the after-tax value of: the net unearned premium reserve, deferred acquisition costs, the present value of estimated net future installment premiums, and the unrealized gain or loss on investment agreement liabilities. The definition of ABV used by the Company may differ from definitions of ABV used by other public holding companies of financial guarantee insurers. The adjustments to book value described above will not be realized until future periods and may differ materially from the amounts used in determining ABV. 30 REPORT ON MANAGEMENT'S RESPONSIBILITIES The management of Ambac Financial Group, Inc. is responsible for the integrity and objectivity of the financial statements and all other financial information presented in this Annual Report and for assuring that such information fairly presents the consolidated financial position and operating results of Ambac Financial Group, Inc.

("AFGI") is a holding company whose subsidiaries provide financial guarantee insurance and financial management services to clients in both the public and private sectors in the United States and abroad. AFGI's principal operating subsidiary, Ambac Assurance Corporation ("Ambac Assurance"), a leading insurer of municipal and structured finance obligations, has earned triple-A ratings, the highest ratings available from Moody's Investors Service, Inc., Standard & Poor's Ratings Group, Fitch IBCA, Inc., and Japan Rating and Investment Information, Inc. AFGI's Financial Management Services segment provides investment agreements, interest rate swaps, and investment advisory and cash management services, principally to states, municipalities and their authorities, school districts, and hospitals and health organizations. 2 SIGNIFICANT ACCOUNTING POLICIES The accompanying Consolidated Financial Statements of AFGI and subsidiaries (the "Company") have been prepared on the basis of U.S. 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 the Company are described below: CONSOLIDATION: The consolidated financial statements include the accounts of AFGI and its subsidiaries. All significant intercompany balances have been eliminated. NET INCOME PER SHARE AND NET INCOME PER DILUTED SHARE: Net income per share is based on the weighted average number of shares outstanding during the year, retroactively adjusted to reflect a two-for-one stock split in 1997. Net income per diluted share reflects the potential dilution that would occur if securities, such as employee stock options, were exercised. INVESTMENTS: The Company'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 on quotes 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 component of "Accumulated Other Comprehensive Income" in stockholders' 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 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. LOANS: Loans are reported at their outstanding unpaid principal balances, net of any deferred fees. Interest income is accrued on the unpaid principal balance. Deferred fees are amortized to interest income over the contractual life of the loan using the interest method or the straight-line method if not materially different. OBLIGATIONS UNDER INVESTMENT AND PAYMENT AGREEMENTS: Obligations under investment and payment agreements and investment repurchase agreements are recorded as liabilities on the Consolidated Balance Sheets at the face value of the agreement, adjusted for draws paid and interest credited to the account. Unsettled agreements are accrued on a trade-date basis on the Consolidated Balance Sheets at the time of commitment. Interest expense is computed based upon daily outstanding settled liability balances at rates and periods specified in the agreements. Net interest income relating to investment agreements and investment repurchase agreements is included as a component of Financial Management Services revenue. PREMIUM REVENUE RECOGNITION: Premiums can be structured in two ways: (1) computed as a percentage of principal and interest insured, typically collected in a single payment at policy inception date, and earned pro-rata over the period of risk; and (2) computed as a percentage of either principal or principal and interest insured, collected periodically (i.e., monthly, quarterly or annually), and reflected in income pro-rata over the period covered by the premium payment. When a new or secondary market issue insured by Ambac Assurance has been refunded or called, the remaining unearned premium (net of refunding credits, if any) is generally earned at that time. 36 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 expected annual levels of debt service defaults resulting from credit failures on currently insured issues that are not presently or imminently in default. 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. During 1998, 1997 and 1996, paid losses, net of salvage received, were ($7,030), $2,474 and $9,554, respectively. All or part of case basis loss reserves are allocated from any ACR available. Ambac Assurance'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 that 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 $18,248, $14,213 and $12,553 for 1998, 1997 and 1996, respectively. Deferred acquisition costs, net of such amortization, amounted to $14,623, $11,784 and $11,592 for 1998, 1997 and 1996, 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, 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. DERIVATIVE CONTRACTS: DERIVATIVE CONTRACTS HELD FOR PURPOSES OTHER THAN TRADING: The Company uses derivative contracts (primarily interest rate swaps and futures contracts) for hedging purposes as part of its overall interest rate risk management. The Company accounts for its futures contracts in accordance with the provisions of FAS Statement 80, "Accounting for Futures Contracts" ("FAS 80"). FAS 80 permits hedge accounting for 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. Futures contracts held for purposes other than trading are used primarily to hedge interest sensitive assets and liabilities. Futures contracts are designated at inception as a hedge to specific assets and liabilities. Gains and losses on futures and options contracts that qualify as accounting hedges of existing assets or liabilities are included as a component of "Accumulated Other Comprehensive Income" in stockholders' equity, net of deferred tax, and amortized over the remaining lives of the assets and liabilities as an adjustment to interest income or expense. When the hedged asset is sold, or the hedged liability is settled, the unamortized gain or loss on the related hedge is recognized in income. 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 as a component of "Accumulated Other Comprehensive Income" in stockholders' equity, net of deferred tax. Interest rate risk is managed through the linkage of the interest rate swaps, which synthetically changes the nature of the underlying asset or liability (for example, from a fixed to floating interest rate obligation). Gains and losses on futures contracts, purchased options or interest rate swaps that do not qualify as accounting hedges are recognized immediately in current period income. DERIVATIVE CONTRACTS HELD FOR TRADING PURPOSES: The Company, through its subsidiary Ambac Financial Services, L.P. ("AFSLP"), a provider of interest rate swaps to states, municipalities and their authorities, and other entities in connection with their financings, uses derivative contracts which are classified as held for trading purposes. Derivative contracts are recorded on trade date at fair value. Changes in fair value are recorded as a component of Financial Management Services segment income. The fair value of interest rate swaps is determined through the use of valuation models. Interest rate swaps are recorded on the balance sheet on a gross basis; assets and liabilities are netted by customer only when a legal right of set-off exists. INCOME TAXES: AFGI files a consolidated federal income tax return with its subsidiaries. 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 37 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Dollars in thousands, except per share amounts) tax rates is recognized in the period that includes the enactment date. The Internal Revenue Code permits financial guarantee insurance companies to deduct from taxable income, subject to certain limitations, the amounts added to the statutory mandatory contingency reserve for municipal obligations during the year. The deduction taken is allowed only to the extent that U.S. Treasury noninterest-bearing tax and loss bonds are purchased at their par value prior to the original due date of the Company's consolidated federal tax return and held 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 may redeem the tax and loss bonds to satisfy the additional tax liability. The purchases of tax and loss bonds are recorded as payments of federal income taxes. POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS: The Company provides various postretirement and post-employment 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. STOCK COMPENSATION PLANS: In 1997, the Company adopted the Ambac 1997 Equity Plan. Under this plan, awards are granted to eligible employees of the Company in the form of incentive stock options or other stock-based awards. The Company accounts for its incentive stock options and stock-based awards under FAS Statement 123, "Accounting for Stock-Based Compensation" ("FAS 123"). FAS 123 permits a company to choose either the fair value based method of accounting as defined in the Statement or the intrinsic value based method of accounting as prescribed by APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"), for its stock-based compensation plans. Companies electing the accounting requirements under APB 25 must also make pro-forma disclosures of net income, earnings per share and earnings per diluted share as if the fair value based method of accounting had been applied. The Company has elected to account for its plans under APB 25. ACCOUNTING STANDARDS: During 1998, the Company adopted the following new standards: FAS Statement 130, "Reporting Comprehensive Income" ("FAS 130"); FAS Statement 131, "Disclosures about Segments of an Enterprise and Related Information" ("FAS 131"); and FAS Statement 132, "Employers' Disclosures about Pensions and Other Postretirement Benefits" ("FAS 132"). FAS 130 establishes standards for the reporting and presentation of comprehensive income and its components in a full set of financial statements. Comprehensive income encompasses all changes in stockholders' equity (except those arising from transactions with stockholders) and includes net income, net unrealized capital gains or losses on available-for-sale securities and foreign currency translation adjustments. Comprehensive income is disclosed in the Consolidated Statement of Stockholders' Equity. FAS 131 redefines how reportable segments are determined and requires disclosure of certain financial and descriptive information about a company's reportable segments. Disclosures regarding the Company's two reportable segments, Financial Guarantee Insurance and Financial Management Services are included in Note 17. FAS 132 alters disclosure requirements regarding pensions and other postretirement benefits in the financial statements of employers who sponsor such benefit plans. The revised disclosure requirements are designed to provide additional information to assist readers in evaluating future costs related to such plans. The required pension disclosures are included in Note 10. As each of these new standards only requires additional disclosure information in the consolidated financial statements, they do not affect the Company's consolidated financial position or results of operations. In June 1998, the Financial Accounting Standards Board issued FAS Statement 133, "Accounting for Derivative Instruments and Hedging Activities" ("FAS 133"). FAS 133 establishes accounting and reporting standards for derivative instruments and hedging activities. The statement requires all derivatives to be recorded on the balance sheet at fair value and establishes special accounting for the following three different types of hedges: (1) hedges of changes in the fair value of assets, liabilities or firm commitments (referred to as fair value hedges); (2) hedges of the variable cash flows of forecasted transactions (cash flow hedges); and (3) hedges of foreign currency exposures of net investments in foreign operations. Though the accounting treatment and criteria for each of the three types of hedges is unique, they all result in recognizing offsetting changes in value or cash flow of both the hedge and the hedged item in earnings in the same period. Changes in the fair value of derivatives that do not meet the criteria of one of these three categories of hedges are included in earnings in the period of the change with no related offset. FAS 133 is effective for years beginning after June 15, 1999, but companies may adopt early. The Company will adopt FAS 133 effective January 1, 2000. Management is assessing the impact of FAS 133 on the Company's consolidated financial position and results of operations. RECLASSIFICATIONS: Certain reclassifications have been made to prior years' amounts to conform to the current year's presentation. 3 INVESTMENTS The amortized cost and estimated fair value of investments in fixed income securities and short-term investments at December 31, 1998 and 1997 were as follows: 38 =========================================================================== Gross Gross Estimated Amortized Unrealized Unrealized Fair Cost Gains Losses Value - --------------------------------------------------------------------------- 1998 Municipal obligations $2,632,276 $172,960 $3,912 $2,801,324 Corporate obligations 1,335,749 103,030 3,352 1,435,427 U.S. Government obligations 114,385 8,511 - 122,896 Mortgage- and asset- backed securities (includes U.S. Government Agency obligations) 4,224,636 41,994 3,995 4,262,635 Other 119,528 - - 119,528 - --------------------------------------------------------------------------- Total $8,426,574 $326,495 $11,259 $8,741,810 =========================================================================== 1997 Municipal obligations $2,146,137 $152,971 $ 112 $2,298,996 Corporate obligations 1,022,995 71,520 928 1,093,587 U.S. Government obligations 136,771 2,855 28 139,598 Mortgage- and asset- backed securities (includes U.S. Government Agency obligations) 3,200,262 25,511 3,017 3,222,756 Other 155,763 91 669 155,185 - --------------------------------------------------------------------------- Total $6,661,928 $252,948 $ 4,754 $6,910,122 =========================================================================== The amortized cost and estimated fair value of fixed income securities and short-term investments at December 31, 1998, by contractual maturity, were as follows: ========================================================================= Estimated Amortized Fair Cost Value - ------------------------------------------------------------------------- Due in one year or less $ 250,741 $ 252,235 Due after one year through five years 222,466 232,054 Due after five years through ten years 399,846 423,355 Due after ten years 3,328,885 3,571,531 - ------------------------------------------------------------------------- 4,201,938 4,479,175 Mortgage- and asset-backed securities 4,224,636 4,262,635 - ------------------------------------------------------------------------- $8,426,574 $8,741,810 ========================================================================= 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 $6,191 and $8,415 at December 31, 1998 and 1997, respectively, were deposited by the Company with governmental authorities or designated custodian banks as required by laws affecting insurance companies. Net investment income from the Financial Guarantee Insurance segment comprised the following: ========================================================================== 1998 1997 1996 - -------------------------------------------------------------------------- Fixed income securities $181,437 $155,810 $139,410 Short-term investments 8,139 6,506 7,999 - -------------------------------------------------------------------------- Total investment income 189,576 162,316 147,409 Investment expense (3,386) (2,607) (2,468) - -------------------------------------------------------------------------- Net investment income $186,190 $159,709 $144,941 ========================================================================== The Financial Guarantee Insurance segment had gross realized gains of $14,219, $25,641 and $19,236 for 1998, 1997 and 1996, respectively, and gross realized losses of $10,484, $4,557 and $39,767 for 1998, 1997 and 1996, respectively. The Financial Management Services segment had gross realized gains of $22,592, $3,766 and $3,406 for 1998, 1997 and 1996, respectively, and gross realized losses of $39,688, $4,403 and $3,013 for 1998, 1997 and 1996, respectively. Gross realized gains and losses includes amounts related to a trading position, which represented a small portion of the Company's assets, containing high quality municipal bonds hedged with treasury futures. These gains were $2,967, $1,309 and $0 for 1998, 1997 and 1996, respectively, and losses of $18,638, $3,578 and $0 for 1998, 1997 and 1996, respectively. Gross realized losses also include the Company's $11,548 write-off of its investment in Ambac Connect, Inc. in 1998. Net investment income related to the investment agreement business comprises gross investment income less related interest expense, and is a component of Financial Management Services revenue. For 1998, 1997 and 1996, gross investment income from investment agreements was $281,904, $200,337 and $165,196, respectively, and the related interest expense was $263,586, $186,678 and $154,484, respectively. As of December 31, 1998 and 1997, the Company held securities subject to agreements to resell for $252,295 and $85,466, respectively. These securities were held as collateral by the Company under agreements that had terms of less than 30 days. As of December 31, 1998 and 1997, the Company had pledged (or sold under agreements to repurchase) securities purchased under agreements to resell and investment securities to certain municipalities, with a fair value of $3,636,519 and $2,714,719, respectively, in connection with certain investment agreements (including agreements structured as investment repurchase agreements). During 1998, the Company entered into security borrowing agreements, the purpose of which was to limit the Company's cost of collateralizing certain investment agreements (including agreements structured as investment repurchase agreements) by reducing the use of securities purchased under agreements to resell. The security borrowing agreements allow the Company to borrow securities with a maximum market value of $1,000,000. The borrowings are secured by Company-owned investment securities. As of December 31, 1998, the Company had $750,000 in outstanding securities borrowed. The borrowings and related pledged securities are classified as "Payable to brokers and dealers" and "Receivable from brokers and dealers," respectively, on the Consolidated Balance Sheets. 4 LOANS In the normal course of business, the Company has extended loans to customers participating in certain structured municipal transactions. The loans are collateralized with cash that the customers have deposited with a payment custodian in amounts adequate to repay the loan balance and interest thereon. Equipment and other assets underlying the transactions serve as additional collateral for the loans. The Company may act as the payment custodian and hold the funds posted as collateral. 39 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Dollars in thousands, except per share amounts) As of December 31, 1998 and 1997, the interest rates on these loans ranged from 6.25% to 8.42%. 5 REINSURANCE In the ordinary course of business, Ambac Assurance 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: ========================================================================== Years Ended December 31, 1998 1997 1996 - -------------------------------------------------------------------------- Written Earned Written Earned Written Earned - -------------------------------------------------------------------------- Direct $333,652 $238,452 $277,814 $176,009 $240,544 $155,883 Assumed 27,359 7,367 8,349 3,614 6,664 3,126 Ceded (49,563) (33,135) (32,452) (25,623) (37,793) (22,380) - -------------------------------------------------------------------------- Net premiums $311,448 $212,684 $253,711 $154,000 $209,415 $136,629 ========================================================================== The reinsurance of risk does not relieve the ceding insurer of its original liability to its policyholders. 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. There were no reinsurance recoverables on paid losses as of December 31, 1998 and 1997. As of December 31, 1998, prepaid reinsurance of approximately $159,361 was associated with Ambac Assurance's three largest reinsurers. As of December 31, 1998, Ambac Assurance held letters of credit and collateral amounting to approximately $198,957 from its reinsurers to cover liabilities ceded under the aforementioned reinsurance contracts. Ambac Assurance and MBIA Insurance Corporation ("MBIA") formed an unincorporated joint venture, MBIAoAMBAC International, in 1995. The joint venture was formed with the goal of bringing the combined capital and human resources of the two companies together to more efficiently serve the international market. Under the joint venture arrangement, financial guarantee policies are issued separately by each of the companies. Premiums assumed from MBIA were $18,715, $8,009 and $4,674 in 1998, 1997 and 1996, respectively. Premiums ceded to MBIA were $15,505, $8,874 and $6,532 in 1998, 1997 and 1996, respectively. 6 STOCKHOLDERS' EQUITY The Company is authorized to issue 200,000,000 shares of common stock, par value $0.01 per share, of which 70,680,384 were issued as of December 31, 1998. The Company is also authorized to issue 4,000,000 shares of preferred stock, $0.01 par value per share, none of which was issued and outstanding as of December 31, 1998. Dividends declared per share amounted to $0.38, $0.345 and $0.3075 in 1998, 1997 and 1996, respectively. The Board of Directors of the Company (the "Board") has authorized the establishment of a stock repurchase program that permits the repurchase of up to 6,000,000 shares of the Company's common stock. As of December 31, 1998, approximately 4,248,000 shares had been repurchased under this program for an aggregate amount of $142,700. STOCKHOLDER RIGHTS PLAN: The Company adopted a Stockholder Rights Plan under which stockholders received (after giving effect to a stock split since adoption of the Plan) one Right for each two shares of common stock owned. Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share, at a purchase price of $190 per share. The Rights generally detach and become exercisable when any person or group acquires 20% or more (or announces a tender offer for 20% or more) of the Company's common stock, at which time each Right (other than those held by the acquiring company) will entitle the holder to receive that number of shares of common stock of the Company with a value of two times the exercise price of the Right. If the Company is acquired in a merger or other business combination transaction in which the Company is not the surviving corporation or 50% or more of the Company's assets, cash flow or earning power is sold or transferred, each Right will entitle the holder to receive that number of shares of stock of the acquiring company having a value equal to two times the exercise price of the Right. The Rights, which expire on January 31, 2006, are redeemable in whole, but not in part, by action of the Board at a price of $0.01 per Right at any time prior to their becoming exercisable. 7 COMMITMENTS AND CONTINGENCIES The Company is responsible for leases on the rental of office space. 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 - ------------------------------- 1999 $ 7,067 2000 7,076 2001 6,174 2002 6,115 2003 6,091 All later years 88,369 - ------------------------------- $120,892 =============================== Rent expense for the aforementioned leases amounted to $5,537, $5,048 and $3,862 for the years ended December 31, 1998, 1997 and 1996, respectively. Total rentals to be received under future sublease agreements is estimated at $5,125. 8 INSURANCE REGULATORY RESTRICTIONS Ambac Assurance is subject to insurance regulatory requirements of the States of Wisconsin and New York, 40 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 (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 Assurance paid cash dividends of $48,000, $44,000 and $40,000 on its common stock in 1998, 1997 and 1996, respectively. In addition, on April 30, 1996, Ambac Assurance, in conjunction with the sale of the Company's remaining holdings in HCIA, Inc. ("HCIA") common stock, delivered to the Company (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. Based upon these restrictions, at December 31, 1998, the maximum amount that will be available during 1999 for payment of dividends by Ambac Assurance is approximately $116,200. 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 qualified statutory capital, which is defined as the sum of 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 Ambac Assurance's qualified statutory capital. 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 $1,162,639 and $1,006,829 at December 31, 1998 and 1997, respectively. Qualified statutory capital was $1,920,298 and $1,655,554 at December 31, 1998 and 1997, respectively. Statutory net income for Ambac Assurance was $271,808, $198,615 and $222,810 for 1998, 1997 and 1996, respectively. Statutory capital and surplus differs from stockholders' equity determined under GAAP principally due to statutory accounting rules that treat loss reserves, premiums earned, policy acquisition costs, and deferred income taxes differently. 9 INCOME TAXES The Company's provision for income taxes is comprised of the following: 1998 1997 1996 ====================================================================== Current taxes $72,608 $51,036 $94,392 Deferred taxes 2,310 11,930 4,797 - ---------------------------------------------------------------------- $74,918 $62,966 $99,189 ====================================================================== The total effect of income taxes on income and stockholders' equity for the years ended December 31, 1998 and 1997 was as follows: ====================================================================== 1998 1997 - ---------------------------------------------------------------------- Total income taxes charged to income $ 74,918 $ 62,966 - ---------------------------------------------------------------------- Income taxes (credited) charged to stockholders' equity: Unrealized gains on bonds 12,587 45,192 Exercise of stock options (19,144) (5,566) - ---------------------------------------------------------------------- Total (credited) charged to stockholders' equity (6,557) 39,626 - ---------------------------------------------------------------------- Total effect of income taxes $ 68,361 $102,592 ====================================================================== The tax provisions in the accompanying consolidated statements of operations reflect effective tax rates differing from prevailing federal corporate income tax rates. The following is a reconciliation of these differences: ============================================================================ 1998 % 1997 % 1996 % - ---------------------------------------------------------------------------- Computed expected tax at statutory rate $115,119 35.0% $100,099 35.0% $131,427 35.0% Reductions in expected tax resulting from: Tax-exempt interest (38,926) (11.8) (35,682) (12.5) (30,760) (8.2) Other, net (1,275) (0.4) (1,451) (0.5) (1,478) (0.4) - ---------------------------------------------------------------------------- Income tax expense $ 74,918 22.8% $ 62,966 22.0% $ 99,189 26.4% ============================================================================ The tax effects of temporary differences that give rise to significant portions of the deferred tax liabilities and deferred tax assets at December 31, 1998 and 1997 are presented below: ======================================================================== 1998 1997 - ------------------------------------------------------------------------ Deferred tax liabilities: Contingency reserve $119,150 $115,360 Unrealized gains on bonds 87,930 75,342 Deferred acquisition costs 42,583 38,030 Unearned premiums 36,728 35,679 Investments 2,442 1,491 Other 1,189 2,026 - ------------------------------------------------------------------------ Total deferred tax liabilities 290,022 267,928 - ------------------------------------------------------------------------ Deferred tax assets: Tax and loss bonds 88,471 87,951 Loss reserves 27,918 17,182 Alternative minimum tax carryforward 7,001 14,049 Amortization and depreciation 5,406 6,032 Compensation 12,009 4,030 Other 3,435 3,456 - ------------------------------------------------------------------------ Sub-total deferred tax assets 144,240 132,700 Valuation allowance - - - ------------------------------------------------------------------------ Total deferred tax assets 144,240 132,700 - ------------------------------------------------------------------------ Net deferred tax liabilities $145,782 $135,228 ======================================================================== The Company believes that no valuation allowance is necessary in connection with the deferred tax assets. 41 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Dollars in thousands, except per share amounts) 10 EMPLOYEE BENEFITS PENSIONS: The Company has a defined benefit pension plan covering substantially all employees of the Company. The benefits are based on years of service and the employee's compensation during the last five years of employment. The Company'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, 1998 and 1997. ======================================================================== 1998 1997 - ------------------------------------------------------------------------ Change in Projected Benefit Obligation: Projected benefit obligation at beginning of year $ 9,374 $ 8,189 Service cost 691 723 Interest cost 684 601 Amendments 116 - Actuarial loss 1,843 114 Benefits paid (275) (253) - ------------------------------------------------------------------------ Projected benefit obligation at end of year $12,433 $ 9,374 - ------------------------------------------------------------------------ Change in Plan Assets: Fair value of plan assets at beginning of year $ 9,644 $ 8,153 Actual return on plan assets 1,595 1,635 Company contributions - 138 Benefits paid (275) (253) Expenses paid (30) (29) - ------------------------------------------------------------------------ Fair value of plan assets at end of year $10,934 $ 9,644 - ------------------------------------------------------------------------ Funded status $ (1,499) $270 Unrecognized net loss 1,118 62 Unrecognized prior service cost (1,289) (1,454) Unrecognized net transition asset (4) (7) - ------------------------------------------------------------------------ Pension liability included in other liabilities $ (1,674) $(1,129) ======================================================================== Net pension costs for 1998, 1997 and 1996 included the following components: ============================================================================ 1998 1997 1996 - ---------------------------------------------------------------------------- Service cost $ 807 $ 723 $ 674 Interest cost on expected benefit obligation 684 601 539 Expected return on plan assets (793) (701) (613) Amortization of unrecognized transition asset (3) (3) (3) Amortization of prior service cost (165) (165) (165) Recognized net actuarial loss 15 33 87 - ---------------------------------------------------------------------------- Net periodic pension cost $ 545 $ 488 $ 519 ============================================================================ The discount rate used in the determination of the actuarial present value for the projected benefit obligation was 6.50% and 7.25% for 1998 and 1997, respectively. The expected long-term rate of return on assets was 9.25% for both 1998 and 1997. The rate of increase in future compensation levels used in determining the actuarial present value of the projected benefit obligation was 5.0 % and 4.8% for 1998 and 1997, respectively. Substantially all employees of the Company 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 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 was $2,063, $1,806 and $1,680 in 1998, 1997 and 1996, respectively. ANNUAL INCENTIVE PROGRAM: The Company has an annual incentive program that provides for awards to key officers and employees based upon predetermined criteria. The cost of the program in 1998, 1997 and 1996 amounted to $16,095, $12,038 and $10,822, respectively. POSTRETIREMENT HEALTH CARE AND OTHER BENEFITS: Ambac Assurance provides certain medical and life insurance benefits for retired employees and eligible dependents. All plans are contributory. None of the plans are currently funded. Postretirement benefits expense was $316, $262 and $220 in 1998, 1997 and 1996, respectively. The unfunded accumulated postretirement benefit obligation was $3,121 and the related accrued postretirement liability was $1,956 as of December 31, 1998. The assumed health care cost trend rates range from 8.0% in 1999, decreasing ratably to 5.5% in 2003, 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, 1998 by $554 and the 1998 benefit expense by $79. The weighted average discount rate used to measure the accumulated postretirement benefit obligation and 1998 expense was 6.50%. 11 INSURANCE IN FORCE The par amount of bonds insured, net of reinsurance, was $198,274,000 and $165,601,000 at December 31, 1998 and 1997, respectively. As of December 31, 1998 and 1997, the insured portfolio was diversified by type of insured bond as shown in the following table: 42 =============================================================================== Net Par Amount Outstanding - ------------------------------------------------------------------------------- (Dollars in millions) 1998 1997 - ------------------------------------------------------------------------------- Domestic: Municipal finance: General obligation $ 37,502 $ 36,324 Lease and tax-backed revenue 36,929 30,980 Utility revenue 27,014 24,913 Health care revenue 20,071 18,545 Investor-owned utilities 8,013 6,255 Transportation revenue 7,831 7,370 Higher education 7,720 6,852 Housing revenue 6,445 6,064 Student loans 4,528 3,516 Other 873 597 - ------------------------------------------------------------------------------- Total municipal finance 156,926 141,416 - ------------------------------------------------------------------------------- Structured finance: Mortgage-backed and home equity 19,478 11,620 Commercial asset-backed 10,015 4,538 Other consumer asset-backed 2,132 1,514 Banks/financial institutions 671 524 Other 567 439 - ------------------------------------------------------------------------------- Total structured finance 32,863 18,635 - ------------------------------------------------------------------------------- Total domestic 189,789 160,051 - ------------------------------------------------------------------------------- International finance: Commercial asset-backed 3,180 2,600 Banks/financial institutions 1,514 283 Utilities 1,073 456 Sovereign/sub-sovereign 1,027 981 Mortgage-backed and home equity 607 496 Other 1,084 734 - ------------------------------------------------------------------------------- Total international finance 8,485 5,550 - ------------------------------------------------------------------------------- $198,274 $165,601 =============================================================================== As of December 31, 1998 and 1997, the international insured portfolio is shown in the following table by location of risk: ============================================================================== Net Par Amount Outstanding - ------------------------------------------------------------------------------ (Dollars in millions) 1998 1997 - ------------------------------------------------------------------------------ United Kingdom $2,289 $ 865 Australia 779 63 France 692 1,032 Japan 675 879 Italy 571 555 Internationally diversified (1) 1,621 899 Other international 1,858 1,257 - ------------------------------------------------------------------------------ Total International $8,485 $5,550 ============================================================================== (1) Internationally diversified represents insured policies with multiple locations of risk. Direct insurance in force (principal and interest) was $367,801,000 and $321,104,000 at December 31, 1998 and 1997, respectively. Net insurance in force (after giving effect to reinsurance) was $317,668,000 and $275,931,000 as of December 31, 1998 and 1997, respectively. 12 FINANCIAL INSTRUMENTS HELD FOR PURPOSES OTHER THAN TRADING DERIVATIVE FINANCIAL INSTRUMENTS: In the normal course of business, the Company becomes a party to various financial instruments to reduce its exposure to fluctuations in interest rates. These financial instruments include interest rate swaps, exchange traded futures contracts and purchased interest rate options. The notional amounts of these financial instruments were as follows: ============================================================================== As of December 31, 1998 1997 - ------------------------------------------------------------------------------ Derivative financial instruments with off-balance sheet risk: Interest rate futures contracts $5,836,700 $3,689,100 Interest rate swaps 590,468 712,206 Other: Purchased interest rate options 15,000 85,500 ============================================================================== 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. As discussed in Note 2, interest rate futures and purchased option contracts held for purposes other than trading are used primarily to hedge interest rate risk inherent in the portfolio of interest-sensitive assets and liabilities. Interest rate swaps held for purposes other than trading are used to manage interest rate risk by synthetically changing the nature of specific assets or liabilities. Futures contracts are purchased to hedge interest rate risk inherent in fixed rate liabilities. Futures contracts are sold to hedge interest rate risk inherent in fixed rate investment securities. Interest rate option contracts are purchased to hedge interest rate risk inherent in fixed rate assets and liabilities. At December 31, 1998 and 1997, futures and purchased option contracts with an outstanding notional of $360,700 and $627,000, respectively, were designated as hedges of fixed rate liabilities. Additionally, at December 31, 1998 and 1997, futures and purchased option contracts with an outstanding notional of $5,491,000 and $3,147,600, respectively, were designated as hedges of fixed rate investment securities. Interest rate swaps that require the Company to pay a fixed rate are used primarily to hedge fixed rate investment securities. Interest rate swaps that require the Company to receive a fixed rate are used primarily to hedge fixed rate liabilities. The table below summarizes, for each major type of swap, the weighted average fixed rate paid or received on the respective notional amounts outstanding. Notional amounts are used to calculate the contractual payments to be exchanged. ================================================================================ Pay fixed swaps: Receive fixed swaps: Maturing Weighted Weighted Range of implied After Notional average Notional average floating interest December 31, amount fixed rate amount fixed rate rates - -------------------------------------------------------------------------------- 1999 $299,775 6.98% $12,922 6.46% 4.98% to 5.16% 2000 202,368 7.02% 12,271 6.46% 5.08% to 5.25% 2001 161,145 6.93% 11,602 6.46% 5.23% to 5.35% 2002 173,144 6.93% 10,913 6.46% 5.32% to 5.45% 2003 182,783 6.93% 10,205 6.46% 5.45% to 5.52% Thereafter 53,924 7.08% 20,354 7.07% ================================================================================ The floating rate side of the Company's interest rate swaps is based on several indices, primarily one-month, three-month and six-month LIBOR. The floating rates shown above reflect the range of the implied forward LIBOR yield curve for those indices, as of December 31, 1998. 43 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Dollars in thousands, except per share amounts) FAIR VALUES OF FINANCIAL INSTRUMENTS HELD FOR PURPOSES OTHER THAN TRADING: Fair value amounts are determined by 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 fixed income investments are based on quoted market prices received from a nationally recognized pricing service or dealer quotes. SHORT-TERM INVESTMENTS AND CASH: The fair values of short-term investments and cash are assumed to equal amortized cost. OTHER: The fair value of other investments, primarily preferred stock, is based on an evaluation of the underlying company and recent transactions in such preferred stock. SECURITIES PURCHASED UNDER AGREEMENTS TO RESELL: The fair value of securities purchased under agreements to resell is assumed to approximate carrying value. LOANS: The fair value of loans is assumed to approximate carrying value. RECEIVABLE/PAYABLE TO BROKERS AND DEALERS: The fair value of receivable/payable to brokers and dealers, representing securities borrowed from various counterparties secured by Company-owned securities, are assumed to approximate carrying value. DEBENTURES: The fair value of the debentures is based on the quoted market prices and dealer quotes. OBLIGATIONS UNDER INVESTMENT, REPURCHASE AND PAYMENT AGREEMENTS (INCLUDING ACCRUED INTEREST): The fair value of the liability for investment agreements and repurchase agreements (including accrued interest) is estimated based upon valuation models using rates currently offered for contracts of similar remaining maturities. The fair value of payment agreements is assumed to approximate carrying value. DERIVATIVE CONTRACTS: Fair values of derivative 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 Assurance's liability under its installment premium policies is measured using the present value of estimated future installment premiums, less an estimated 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 Assurance's liability under these policies. The carrying amount and estimated fair value of financial instruments held for purposes other than trading are presented below: ================================================================================ As of December 31, 1998 1997 - -------------------------------------------------------------------------------- Estimated Estimated Carrying Fair Carrying Fair (Dollars in Millions) Amount Value Amount Value - -------------------------------------------------------------------------------- Financial assets: Fixed income securities $8,622 $8,622 $6,774 $6,774 Short-term investments 120 120 136 136 Other investments 7 7 5 5 Cash 8 8 9 9 Securities purchased under agreements to resell 252 252 85 85 Loans 674 674 503 503 Receivable from brokers and dealers 750 750 - - Financial liabilities: Debentures 424 476 224 269 Obligations under investment, repurchase and payment agreements (including accrued interest) 6,046 5,959 4,367 4,405 Payable to brokers and dealers 750 750 - - Derivative financial instruments: Interest rate futures contracts (4) - (2) - Interest rate swaps (22) (20) (9) (7) Purchased interest rate option contracts - - - - Liability for financial guarantees written: Gross 1,294 906 1,179 855 Net of reinsurance 1,094 766 995 722 Net installment premiums - 216 - 153 ================================================================================ 13 FINANCIAL INSTRUMENTS HELD FOR TRADING PURPOSES AFSLP is a provider of interest rate swaps to states, municipalities and their authorities and other entities in connection with their financings. AFSLP is subject to basis risk (the relationship between tax-exempt and taxable interest rates). If actual or projected tax-exempt interest rates change in relation to taxable rates, the Company will experience an unrealized mark-to-market gain or loss. The AFSLP swap portfolio is considered held for trading purposes. 44 The following table summarizes information about the Company's financial instruments held for trading purposes as of December 31, 1998 and 1997: ============================================================================= Net Estimated Average Net Fair Value Fair Value Notional - ----------------------------------------------------------------- Amount Assets Liabilities Assets Liabilities - ----------------------------------------------------------------------------- 1998: Derivative financial instruments: Interest rate swaps $200,454 $163,043 $130,984 $103,414 $5,357,450 Futures contracts - - - - 706,700 Other financial instruments - - 183,682 181,698 - 1997: Derivative financial instruments: Interest rate swaps $ 67,743 $ 49,265 $ 43,748 $ 33,954 $3,347,190 Futures contracts - - - - 514,900 Other financial instruments 183,041 181,732 160,251 159,213 - ============================================================================= Financial instruments held for trading purposes are carried at estimated fair value. The aggregate amount of net trading income recognized from derivative financial instruments held for trading purposes was $705, $7,454 and $10,579 for 1998, 1997 and 1996, respectively. Other financial instruments held for trading purposes consists of fixed income securities held in 1997 and sold during 1998. The aggregate amount of net trading income recognized from other financial instruments was $2,967, $1,309 and $0 in 1998, 1997 and 1996, respectively. Average net fair values were calculated based on average monthly net fair values. 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. 14 LONG-TERM DEBT AND LINES OF CREDIT The carrying value of long-term debt was as follows: ======================================================================== As of December 31, 1998 1997 - ------------------------------------------------------------------------ 9 3/8% Debentures, due 2011 $149,434 $149,389 7 1/2% Debentures, due 2023 74,495 74,475 7.08% Debentures, due 2098 200,000 - - ------------------------------------------------------------------------ $423,929 $223,864 ======================================================================== The debentures due on August 1, 2011 were issued on August 8, 1991 in the principal amount of $150,000 and bear interest of 9 3/8%, payable on February 1 and August 1 of each year and are non-callable. The debentures due on May 1, 2023 were issued on May 11, 1993 in the principal amount of $75,000 and bear interest of 7 1/2%, payable on May 1 and November 1 of each year and are non-callable. The debentures due on March 31, 2098 were issued on April 1, 1998 in the principal amount of $200,000 and bear interest of 7.08%, payable on March 31, June 30, September 30 and December 31 of each year. The debentures may not be redeemed prior to March 31, 2003 and were sold at 100% of their principal amount. On or after March 31, 2003, the Company may redeem the debentures, in whole at any time or in part from time to time, at 100% of their principal amount, plus accrued interest to the date of redemption. AFGI and Ambac Assurance have a revolving credit facility with three major international banks for $150,000, which expires in August 1999 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, 1998 and 1997, no amounts were outstanding under this credit facility. Ambac Assurance maintains third party capital support in the form of a seven-year irrevocable limited recourse credit facility from a group of highly-rated international banks. This credit facility provides liquidity to Ambac Assurance in the event claims from municipal obligations in its insured portfolio exceed specified levels. Repayment of amounts drawn under the credit facility are limited primarily to the amount of any recoveries of losses related to policy obligations. During 1998, total third party capital support was increased from $500,000 to $555,000 and its expiration reset to December 2005. As of December 31, 1998 and 1997, no amounts were outstanding under this facility. 15 OBLIGATIONS UNDER INVESTMENT AGREEMENTS AND PAYMENT AGREEMENTS Obligations under investment agreements, including those structured in the form of repurchase contracts, are recorded on a trade-date basis. Certain obligations may be called at various times prior to maturity at the option of the counterparty. As of December 31, 1998 and 1997, the interest rates on these agreements ranged from 4.00% to 8.14% and 4.23% to 8.14%, respectively. As of December 31, 1998 and 1997, the average yield on these agreements was 5.70% and 5.85%, respectively. Obligations under investment agreements and investment repurchase agreements as of December 31, 1998 and 1997 were as follows: ================================================================ As of December 31, 1998 1997 - ---------------------------------------------------------------- Settled $5,209,690 $3,817,772 Unsettled 73,142 - - ---------------------------------------------------------------- $5,282,832 $3,817,772 ================================================================ 45 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Dollars in thousands, except per share amounts) Net payments due under settled investment agreements in each of the next five years ending December 31, and the periods thereafter, based on expected draw dates, are as follows: ================================ Principal Amount - -------------------------------- 1999 $2,308,820 2000 1,237,441 2001 554,655 2002 190,338 2003 29,481 All later years 888,955 - -------------------------------- $5,209,690 ================================ Obligations under payment agreements represent funds received by the Company from certain municipal customers. These funds serve as collateral for loans extended by the Company in connection with certain structured municipal transactions. In connection with these transactions, the Company is obligated to make periodic agreed upon payments. As of December 31, 1998 and 1997, the interest rates on these obligations ranged from 6.25% to 8.42%. Net (deposits)/payments due under payment agreements in each of the next five years ending December 31, and the periods thereafter, based on contractual payment dates, are as follows: ================================ Principal Amount - -------------------------------- 1999 $ (11,558) 2000 (6,971) 2001 2,840 2002 8,493 2003 16,248 All later years 664,879 - -------------------------------- $673,931 ================================ 16 COMMON STOCK INCENTIVES The Ambac 1997 Equity Plan (the "Equity Plan") provides for the granting of stock options, stock appreciation rights, restricted stock units, performance units and other awards that are valued or determined by reference to the common stock. Stock options awarded to employees are exercisable and expire as specified at the time of grant. Additionally, such options generally may not have a per share exercise price less than the fair market value of a share of common stock on the date of grant or have a term in excess of ten years from the date of the grant. The Company also maintains the Ambac 1997 Non-Employee Directors Equity Plan (the "Directors Plan"), which provides awards of stock options and restricted stock units to non-employee members of the Company's Board of Directors. The number of options and their exercise price, and the number of restricted stock units, awarded to each non-employee director under the Directors Plan are determined by formula. As of December 31, 1998, approximately 6,070,000 shares were available for future grant under the Equity Plan and the Directors Plan. A summary of option activity is as follows: =============================================================================== 1998 1997 1996 - ------------------------------------------------------------------------------- Weighted Weighted Weighted Average Average Average Exercise Exercise Exercise Shares Price Shares Price Shares Price - ------------------------------------------------------------------------------- Outstanding at beginning of year 3,917,693 $22.15 4,248,642 $19.37 4,140,824 $18.17 Granted 969,698 $47.66 859,800 $33.59 964,150 $24.25 Exercised (1,332,729) $15.78 (898,942) $19.05 (721,724) $18.53 Forfeited (165,298) $34.46 (291,807) $24.99 (134,608) $21.87 --------- --------- --------- Outstanding at end of year 3,389,364 $31.34 3,917,693 $22.15 4,248,642 $19.37 --------- --------- --------- Exercisable 1,941,601 2,392,853 2,407,838 =============================================================================== =============================================================================== Options Outstanding Options Exercisable - ------------------------------------------------------------------------------- Weighted Number Average Weighted Number Weighted Range of outstanding at Remaining Average Exercisable at Average Exercise December 31, Contract Exercise December 31, Exercise Prices 1998 Life Price 1998 Price - ------------------------------------------------------------------------------- $10 to 24 1,780,468 4.7 $22.02 1,584,390 $21.74 $25 to 44 696,446 5.1 $33.56 235,482 $33.52 $45 to 61 912,450 5.6 $47.84 121,729 $53.42 --------- --------- 3,389,364 1,941,601 =============================================================================== The Company applies APB 25 and related interpretations in accounting for its plans. Accordingly, since the fair value of the options at grant date equals the exercise price, no compensation cost has been recognized for its fixed stock option plan. Had compensation cost for the Company's stock-based compensation plan been determined consistent with FAS 123, the Company's net income, earnings per share and earnings per diluted share for the years ended December 31, 1998, 1997 and 1996, would have been reduced to the pro-forma amounts indicated below: ======================================================================== 1998 1997 1996 - ------------------------------------------------------------------------ Net Income: As reported $253,994 $223,030 $276,317 Pro-forma $248,089 $218,852 $273,528 Earnings per share: As reported $3.63 $3.19 $3.95 Pro-forma $3.55 $3.13 $3.91 Earnings per diluted share: As reported $3.56 $3.13 $3.91 Pro-forma $3.48 $3.07 $3.87 ======================================================================== The weighted-average fair value (determined as of the date of the grants) of options granted in 1998, 1997 and 1996 was $13.09 per share, $9.85 per share, and $6.19 per share, respectively. The fair value of each option grant issued was estimated as of the date of the grant using the Black-Scholes option-pricing model, with the following weighted-average assumptions used for grants in 1998, 1997 and 1996, respectively: (i) dividend yield of 0.85%, 1.08% and 1.24%; (ii) expected volatility of 20.5%, 19.4% and 16.5%; (iii) risk-free interest rates of 5.5%, 6.4% and 6.2%; and (iv) expected lives of 5 years, 6 years and 5 years. The pro-forma amounts disclosed above are not likely to be representative of the effects of reported pro-forma net income for future years because options vest over several years and additional awards are granted each year. 46 17 SEGMENT INFORMATION The Company has two reportable segments, as follows: (1)Financial Guarantee Insurance, which provides insurance of municipal and structured finance obligations; and (2) Financial Management Services, which provides investment agreements, interest rate swaps, and investment advisory and cash management services. During the fourth quarter of 1998, the Company discontinued its operations relating to electronic commerce applications for the municipal marketplace. Balances relating to the electronic commerce business are included in the Financial Management Services segment below. Total losses before income taxes for the electronic commerce business was $6,946, $3,557 and $617 for the years ended December 31, 1998, 1997 and 1996, respectively. Also included below for both revenues and income before income taxes for the Financial Management Services segment is a $11,548 charge representing the write-off of the investment in Ambac Connect. The Company's reportable segments are strategic business units that offer different products and services. They are managed separately because each business requires different marketing strategies, personnel skill sets and technology. The accounting policies of the segments are the same as those described in Note 2, "Significant Accounting Policies." Pursuant to insurance and indemnity agreements, Ambac Assurance guarantees the swap and investment agreement obligations of those financial management services subsidiaries. Intersegment revenues include the premiums earned under those agreements. Such premiums are accounted for as if they were premiums to third parties, that is, at current market prices. Information provided below for "Corporate and Other" relates to AFGI corporate activities. Revenue from unaffiliated customers of $16,232 and $7,955 consists primarily of interest income from investment securities for the years ended December 31, 1998 and 1997, respectively. Revenue from unaffiliated customers in 1996 of $164,242 includes a one-time gain from the sale of a subsidiary of approximately $155,600. The following table is a summary of the financial information by reportable segment for the years ended December 31, 1998, 1997 and 1996: ================================================================================================================================= Financial Financial Guarantee Management Corporate Intersegment Total Insurance Services and Other Eliminations Consolidated -
