Item 7.01 Regulation FD Disclosure

On December 3, 2008, Ambac Assurance Corporation ("Ambac Assurance"), a subsidiary of Ambac Financial Group, Inc. (the "Company"), sent put exercise notices to each trust created as a vehicle for providing capital support to Ambac Assurance under the contingent capital facility described in the Company's Annual Report on Form 10-K under "Item 1. Business-Capital and Capital Support." As a result, Ambac Assurance will issue to such trusts a total of 32,000 of its Auction Market Preferred Shares. Ambac Assurance will receive from such trusts approximately $800 million in eight equal payments of approximately $100 million each, on eight different settlement dates, with the first settlement date planned to occur on December 10, 2008 and the final settlement date planned to occur on January 2, 2009. Ambac Assurance is exercising the put in order to enhance liquidity at Ambac Assurance.

On December 2, 2008, the Board of Directors of the Company voted to eliminate its regular quarterly dividend, which most recently had been set at $0.01. This action, which will preserve cash at the parent company amounting to approximately $11.5 million annually, was taken in order to support Company's goal of preserving parent company liquidity.
