Accounting Changes And Error Corrections [Abstract] |
Recently Adopted and Recently Issued Accounting Standards | 14. RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING STANDARDS Adopted: Effective January 1, 2013, Ambac adopted ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities, and ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities retrospectively for all periods presented. Upon the adoption of these ASUs, Ambac presented the offsetting disclosure requirements in Note 10, Derivative Instruments. Effective January 1, 2013, Ambac adopted ASU No. 2013-02, Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income. Upon the adoption of this ASU, Ambac presented the changes in the accumulated balances by component of other comprehensive income and the corresponding effects on net income by line item for the reclassifications out of accumulated other comprehensive income, in Note 5, Comprehensive Income. Issued: In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The objective of this ASU is to eliminate diversity in practice in the presentation of unrecognized tax benefits. The ASU requires an entity to present an unrecognized tax benefit in the financial statements as a reduction to a deferred tax asset for an NOL carryforward, a similar tax loss, or a tax credit carryforward except when: i) an NOL carryforward, a similar tax loss, or a tax credit carryforward is not available as of the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position and ii) the entity does not intend to use the deferred tax asset for this purpose. If either of these conditions exists, an entity should present an unrecognized tax benefit in the financial statements as a liability and should not net the unrecognized tax benefit with a deferred tax asset. The ASU is effective prospectively for reporting periods beginning after December 15, 2013, with early adoption permitted. Ambac will adopt the ASU on January 1, 2014. The adoption of this ASU will not have a material effect on Ambac’s financial statements.
