Ambac Financial Group, Inc. Announces Second Quarter Net Income of $173.0 Million, Down 27%

Ambac Financial Group, Inc. (NYSE: ABK) (Ambac) today announced second quarter 2007 net income of $173.0 million, or $1.67 per diluted share. This represents a 27% decrease from second quarter 2006 net income of $238.6 million, and a 25% decrease in net income per diluted share from $2.22. The decrease is primarily due to unrealized mark-to-market losses amounting to ($56.9) million, or ($0.36) per diluted share, related to credit derivative exposures in the second quarter 2007. The comparable quarter of 2006 included net realized gains on investment securities of $44.4 million, or $0.27 per diluted share, primarily resulting from cash recoveries received related to a security in the investment agreement portfolio that had been written down in prior years. The second quarter 2007 unrealized mark-to-market losses on credit derivative exposures is the result of unfavorable market pricing of collateralized debt obligations with significant amounts of sub-prime residential mortgage collateral. As further described below, net mark-to-market gains and losses on credit derivatives and net gains and losses from sales of investment securities are excluded from the earnings measures used by research analysts. Net Income Per Diluted Share Net income and net income per diluted share are computed in conformity with U.S. generally accepted accounting principles (GAAP). However, many research analysts and investors do not limit their analysis of our earnings to a strictly GAAP basis. In order to assist investors in their understanding of quarterly results, Ambac provides other information. Earnings measures reported by research analysts exclude the net income impact of net gains and losses from sales of investment securities and mark-to-market gains and losses on credit, total return and non-trading derivative contracts (collectively "net security gains and losses”) and certain other items. Certain research analysts and investors further exclude the net income impact of accelerated premiums earned on guaranteed obligations that have been refunded and other accelerated earnings ("accelerated earnings”). During the second quarter 2007, net security gains and losses had the effect of decreasing net income by ($34.6) million, or ($0.34) on a per diluted share basis. Accelerated earnings had the effect of increasing net income by $25.6 million, or $0.25 per diluted share during the quarter. Table I, below, provides second quarter and six-month comparisons of earnings for 2007 and 2006.

Genader, noted, "We are pleased with the breadth and quality of our business production in the quarter. Our rigorous and proven approach enabled us to deliver positive results despite the turmoil in the sub-prime mortgage market that resulted in a negative mark-to-market adjustment. Our triple-A business model offers us key advantages, including our ability to hold insured transactions to maturity; no collateral or margin requirements on transactions insured; and, in the unlikely event of default we pay scheduled principal and interest, thereby minimizing liquidity risk.” Mr. Genader added, "Looking ahead, the disciplined execution of our strategy positions us well to benefit from the improving business conditions we see, with wider spreads, enhanced credit terms and increased demand for our valuable financial guarantee products.” Revenues Highlights Credit enhancement production(1) in the second quarter of 2007 was $367.8 million, down 31% from Ambac's record quarterly production of $531.0 million reported in the second quarter of 2006. Credit enhancement production for the six months of 2007 of $677.9 million was 11% lower than credit enhancement production of $764.4 million in the same period of 2006. Table II, below, provides the second quarter and six-month comparisons of credit enhancement production by market segment for 2007 and 2006. Table II Credit Enhancement Production (1)   $-millions Second Quarter Six Months 2007 2006 % Change 2007 2006 % Change Public Finance $ 114.5 $ 132.1 - 13% $ 229.1 $ 231.2 - 1% Structured Finance 159.1 212.8 - 25% 294.4 303.5 - 3% International 94.2 186.1 - 49% 154.4 229.7 - 33% Total $ 367.8 $ 531.0 - 31% $ 677.9 $ 764.4 - 11% In public finance, Ambac’s premium production decreased even though overall market issuance was up approximately 13%, quarter on quarter. The increase in issuance for the quarter was driven by strong refunding issuance. Ambac’s market share of the insured market was approximately 21%, down slightly from 22% in the comparable prior year quarter. Ambac wrote fewer large, structured transactions in the second quarter of 2007 relative to the comparable prior quarter resulting in the decline in credit enhancement production. U.S. structured finance second quarter credit enhancement production declined from the prior year as the second quarter 2006 production included two large transactions representing 46% of that quarter’s total production. Capital market activity in the U.S. continues to be robust and during the current quarter Ambac benefited from strong writings in pooled debt obligations (CDOs) where both pricing and transaction structure have improved significantly since the beginning of the year. Competition from the senior/subordinated market has dissipated significantly in mortgage-related asset classes. International credit enhancement production also declined relative to an exceptionally strong comparable prior year quarter. Second quarter 2006 international production included two large U.K. transactions that represented almost 48% of the total international production for that quarter. The current quarter saw strong flow in asset backed securitizations. During the quarter Ambac closed deals in seven different countries. Management continues to believe that the broad international markets provide an array of opportunities and will be a driver of short-term and long-term growth for Ambac. Net premiums written (which represent premiums collected during the period, net of reinsurance) in the second quarter of 2007 of $232.7 million were 9% lower than net premiums written of $255.7 million in the comparable period of 2006. The decrease is primarily a result of lower premiums collected up front in public finance and international finance partially offset by lower premiums ceded to reinsurers during the second quarter 2007. Ceded premiums as a percentage of gross premiums written were 10.9% and 18.4% for the second quarter of 2007 and 2006, respectively. Second quarter 2006 ceded premiums were impacted by the number of large deals utilizing reinsurance capacity. Net premiums written for the six months of 2007 of $453.1 million were 6% lower than net premiums written of $483.6 million in the same period of 2006. Excluding the impact of $37.0 million of return premiums from reinsurance cancellations in the first quarter of 2006, net premiums written are up 1%. A breakdown of gross premiums written by market segment and ceded premiums for the second quarter and six-month periods of 2007 and 2006 are included below in Table III. Table III Premiums Written   $-millions Second Quarter Six Months 2007   2006   % Change   2007   2006   % Change   Public Finance $ 111.7 $ 122.9 - 9 % $ 226.1 $ 215.2 + 5 % Structured Finance 87.5 90.2 - 3 % 170.8 169.0 + 1 % International 61.9   100.4   - 38 % 114.1   148.4   - 23 % Total Gross Premiums Written 261.1 313.5 - 17 % 511.0 532.6 - 4 % Ceded Premiums Written (28.4 ) (57.8 ) - 51 % (57.9 ) (49.0 ) + 18 % Net Premiums Written $ 232.7   $ 255.7   - 9 % $ 453.1   $ 483.6   - 6 % Net premiums earned and other credit enhancement fees for the second quarter of 2007 were $238.3 million, which represented a 6% increase from the $225.0 million earned in the second quarter of 2006. The increase was driven by higher accelerated premiums from refundings and policy termination fees, as well as higher normal premiums and other credit enhancement fees. Net premiums earned include accelerated premiums, which result from refundings, calls and other accelerations recognized during the quarter. Accelerated premiums were $43.0 million in the second quarter of 2007, up 15% from $37.4 million in accelerated premiums in the second quarter of 2006. During the second quarter 2007 and 2006, approximately $31.6 million and $23.9 million, respectively, of the accelerated premiums related to U.S. public finance transactions and the remainder related to U.S. structured finance and international transactions. Net premiums earned and other credit enhancement fees for the first half of 2007 were $469.9 million, which represented an 8% increase from the $433.4 million earned in the first half of 2006. Accelerated premiums were $82.8 million for the first half 2007, up 33% from $62.3 million in accelerated premiums for the first half of 2006. Accelerated premiums in 2006 include $7.7 million related to the impact of reinsurance cancellations occurring in the first quarter of 2006. A breakdown of net premiums earned and other credit enhancement fees by market sector for 2007 and 2006 are included below in Table IV. Normal net premiums earned exclude accelerated premiums that result from refundings, calls and other accelerations. Table IV Net Premiums Earned and Other Credit Enhancement Fees   $-millions Second Quarter Six Months 2007 2006 % Change 2007 2006 % Change Public Finance $ 59.1 $ 58.1 + 2% $ 117.5 $ 114.0 + 3% Structured Finance 85.7 77.9 + 10% 167.7 154.8 + 8% International 50.5 51.6 - 2% 101.9 102.3 0 % Total Normal Premiums/Fees 195.3 187.6 + 4% 387.1 371.1 + 4% Accelerated Premiums 43.0 37.4 + 15% 82.8 62.3 + 33% Total $ 238.3 $ 225.0 + 6% $ 469.9 $ 433.4 + 8% Public finance earned premiums, before accelerations, grew 2% this quarter. Earned premium growth in this sector has been negatively impacted by the high level of refunding activity in Ambac’s public finance book in recent years, competitive pricing and the mix of business underwritten in recent periods. Structured finance earned premiums and other credit enhancement fees grew 10%. The rate of growth in structured finance has improved recently, driven by strong premium production in asset classes such as pooled debt obligations and commercial asset-backed securities over the past several quarters. International earned premiums and other credit enhancement fees decreased 2%. The decrease has resulted from deal terminations and a slow down in deal closings in 2007 relative to the prior year. Net investment income for the second quarter of 2007 was $113.2 million, representing an increase of 8% from $104.5 million in the comparable period of 2006. This increase was due primarily to growth in the investment portfolio driven by the ongoing collection of financial guarantee premiums and fees. Net investment income for the six months of 2007 was $225.3 million, representing an increase of 9% from $206.2 million in the comparable period of 2006, primarily as a result of the reasons provided above. Financial services revenues. The financial services segment is comprised of the investment agreement business and the derivative products business. Gross interest income less gross interest expense from investment and payment agreements plus results from the derivative products business, excluding net realized investment gains and losses and unrealized gains and losses on total return swaps and non-trading derivative contracts, was $9.2 million in the second quarter of 2007, down 15% from $10.8 million in the second quarter of 2006. The decrease was primarily due to lower revenue from the interest rate swap, total return swap and investment agreement businesses in the second quarter 2007. Financial services revenues were $19.9 million in the first half of 2007, down 12% from the $22.5 million of revenues in the first half of 2006 primarily due to the reason provided above. Expenses Highlights Financial guarantee expenses of $50.5 million for the second quarter of 2007 increased 13% from $44.7 million of expenses for the second quarter of 2006. Financial guarantee loss and loss expenses were $17.1 million in the second quarter of 2007, up from $12.8 million in the second quarter of 2006. See "Loss Reserve Activity," below, for additional information on losses. Net underwriting and operating expenses of the financial guarantee sector totaled $33.4 million in the second quarter of 2007, up 5% from $31.9 million in the second quarter of 2006 primarily due to increased compensation expense. Financial guarantee expenses of $98.3 million for the first six months of 2007 increased 19% from $82.7 million of expenses for the same period of 2006. The increase results primarily from higher loss expenses during the period. Loss Reserve Activity Case basis loss reserves (loss reserves for exposures that have defaulted) increased $9.6 million during the second quarter of 2007 from $37.7 million at March 31, 2007 to $47.3 million at June 30, 2007. Included in the March 31, 2007 case reserves balance were offsetting receivables for claims previously paid on a European transportation transaction that were deemed by management to be recoverable upon the anticipated successful restructuring of that transaction. The restructuring was finalized during the quarter and the payments due to Ambac were received. Total net claim payments/(receipts) during the quarter amounted to ($7.5) million. Active credit reserves ("ACR") are established for probable and estimable losses due to credit deterioration on certain adversely classified insured transactions. The ACR increased by $14.9 million during the quarter, from $188.8 million at March 31, 2007 to $203.7 million at June 30, 2007. The increase was driven primarily by increases in reserves on certain credits primarily within the transportation sector of the U.S. public finance portfolio and to a lesser extent within the non-subprime RMBS sector of the structured finance portfolio, partially offset by favorable credit activity throughout both portfolios. Other Items Total net securities gains/(losses) for the second quarter of 2007 were ($52.7) million, consisting of net realized gains on investment securities of $1.2 million, net mark-to-market losses on credit and total return derivatives of ($57.9) million and net mark-to-market gains on non-trading derivative contracts of $4.0 million. During the quarter a net mark-to-market loss amounting to ($56.9) million was recorded related to insured collateralized debt obligations of asset-backed securitizations containing sub-prime mortgage-backed securities as collateral. The negative mark-to-market is driven by current market concerns over the most recent vintages of subprime RMBS and the recent lack of liquidity in the CDO of ABS market resulting in a reduction in market-quoted prices. Ambac's exposure on those transactions all attach at levels senior to the triple-A attachment points as established by the rating agencies. For the second quarter of 2006, net securities gains/(losses) were $51.0 million, consisting of net realized gains on investment securities of $44.4 million, net mark-to-market gains on credit and total return derivatives of $7.2 million and net mark-to-market losses on non-trading derivative contracts of ($0.6) million. Approximately $38 million of the second quarter 2006 net realized gains on investment securities related to cash recoveries received from a security in the investment agreement portfolio that had been written down in previous years. Total net securities gains/(losses) for the first half of 2007 were ($49.0) million, consisting of net realized gains on investment securities of $7.8 million, net mark-to-market losses on credit and total return derivatives of ($59.8) million and net mark-to-market gains on non-trading derivative contracts of $3.0 million. For the first half of 2006 net securities gains were $64.4 million, consisting of net realized gains on investment securities of $49.5 million, net mark-to-market gains on credit and total return derivatives of $14.4 million and net mark-to-market gains on non-trading derivative contracts of $0.5 million. Balance Sheet Highlights Total assets as of June 30, 2007 were $21.06 billion, up 4% from total assets of $20.27 billion at December 31, 2006. The increase was primarily driven by cash generated from operations during the period, partially offset by a decrease in unrealized gains in the investment portfolio due to a rise in long-term interest rates. As of June 30, 2007, stockholders' equity was $6.04 billion, a 2% decrease from year-end 2006 stockholders' equity of $6.18 billion. The decrease was primarily the result of the $400 million share buyback and lower Accumulated Other Comprehensive Income driven by higher long-term interest rates, partially offset by net income during the period. During the second quarter 2007, Ambac completed the buyback of $400 million of its common stock under its accelerated share buyback program (originally announced on February 12, 2007). The total number of shares purchased under the agreement amounted to 4.46 million shares. Ambac also bought back 194 thousand shares of its common stock at a total cost of $16.9 million during the second quarter that was unrelated to the accelerated share buyback program. Increased Cash Dividend Declared At its July 2007 Board meeting, the Board of Directors of Ambac Financial Group Inc. approved a 17% increase in the regular quarterly cash dividend from $0.18 to $0.21 per share of common stock. The dividend is payable on September 5, 2007 to stockholders of record on August 10, 2007. Ambac has declared an increased cash dividend in every year since going public in 1991.
