Item 7.01 Regulation FD Disclosure

Set forth below is a list of certain residential mortgage-backed securities (the "RMBS Securities") that are insured by Ambac Assurance Corporation ("AAC") where AAC is conducting a review of loans underlying such RMBS Securities. Such review includes forensic analyses of loan origination files and process and a re-underwriting of loans to determine whether there were breaches of representations and warranties made by the sponsors of such securities at the time such securities were issued. AAC believes, based on its review, that the sponsors of these securities are obligated to pay sums, which may in certain cases be material, to the issuers of some or all of the RMBS Securities listed below and/or to AAC in respect of such breaches of representations and warranties. AAC believes, based on its review and internal calculations, that any recoveries will vary from security to security.

AAC's review with respect to the RMBS Securities listed below is ongoing, and AAC may expand its review from time to time. There can be no assurance as to the outcome of these efforts.
