ABK Ambac Financial Grp. Common Stock

Ambac Financial Group, Inc. (NYSE: ABK) (Ambac) today commented on the Financial Accounting Standards Board�s recently released Statement of Financial Accounting Standards No. 163 - �Accounting for Financial Guarantee Insurance Contracts, an Interpretation of FASB Statement No. 60� (�FAS 163�). The primary focal points of FAS 163 are premium revenue recognition, claim liability recognition and disclosures related to each. Ambac is in the process of analyzing the impact of all aspects of FAS 163 on the financial statements of Ambac. Please refer to previous disclosures regarding the expected impact of the Financial Guarantee Exposure Draft and the FASB�s re-deliberations on the Exposure Draft in Ambac�s Annual Report on Form 10-K for the fiscal year ended December 31, 2007. Ambac expects to update this disclosure in its subsequent reports on Form 10-Q and Form 8-K, which will be available on the Ambac website at www.ambac.com and at the SEC�s website, www.sec.gov. Sean Leonard, Senior Vice President and Chief Financial Officer, commented, �Ambac welcomes this long-awaited statement that will bring industry-wide consistency to accounting for claim liabilities. We note that the final statement has been modified substantially from the exposure draft as the Financial Accounting Standards Board considered certain points made by industry participants in its drafting of the final document.� With respect to loss recognition requirements under the new statement, Mr. Leonard commented, �While there are certain nuances of the new statement regarding recognition of claim liabilities that we need to analyze further, the concept of recognizing such liabilities upon observing credit deterioration and before an actual default is consistent with our current loss recognition methodology. Those that follow our company understand that our active credit reserves, or ACR, are established for probable and estimable losses due to credit deterioration on certain adversely classified insured transactions.� Forward-Looking Statements This release contains statements that may constitute "forward-looking statements" within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
