Our report contains an explanatory paragraph that states that, uncertainties associated with the regulatory oversight of the Company's operating subsidiary, Ambac Assurance Corporation and the inability of its financial guarantee business segment to write new business, management has concluded that there is substantial doubt about the ability of the Company to continue as a going concern. Such factors raise substantial doubt about the Company's ability to continue as a going concern. The consolidated financial statements and financial statement schedules do not include any adjustments that might result from the outcome of this uncertainty. Our report refers to the fact that the Company filed for relief under Chapter 11 of the United States Bankruptcy Code on November 8, 2010. The Company's plan of reorganization became effective and the Company emerged from bankruptcy protection on April 30, 2013. In connection with their emergence from bankruptcy, the Successor Company, Ambac Financial Group, Inc. adopted fresh-start reporting in conformity with ASC Topic 852, "Reorganizations", effective April 30, 2013.
