Ambac Financial Group, Inc. (NYSE: ABK) (Ambac) announced today that the Wisconsin Office of the Commissioner of Insurance (“OCI”) has filed its Plan of Rehabilitation for the Segregated Account of Ambac Assurance Corporation (“the Plan”) in Dane County Circuit Court in Wisconsin.

The Segregated Account of Ambac Assurance Corporation (“Segregated Account”) was established on March 24, 2010, at the direction of the OCI to segregate certain liabilities, primarily policies related to credit derivatives, residential mortgage-backed securities and other structured finance transactions. Policies totaling approximately $57.6 billion of net par outstanding at June 30, 2010, have been allocated to the Segregated Account.

Before the Plan can become effective, it must be confirmed in Wisconsin courts and OCI has stated that it anticipates that the court will schedule a hearing shortly to consider confirmation of the plan. Claims on Segregated Account policies remain subject to a payment moratorium until the Plan becomes effective. The Plan provides that, once it is effective, holders of permitted policy claims will receive 25% of their permitted claims in cash and 75% in surplus notes with a scheduled maturity of June 7, 2020 and bearing interest at 5.1%.

The Plan, along with the Plan Disclosure Statement, supporting exhibits and other information (including schedules of court hearings) can be found on OCI’s web site at
