Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by GAAP for annual periods. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2016. The accompanying consolidated financial statements have not been audited by an independent registered public accounting firm in accordance with the standards of the Public Company Accounting Oversight Board (U.S.), but in the opinion of management such financial statements include all adjustments necessary for the fair presentation of the Company’s consolidated financial position and results of operations. All intercompany balances and transactions have been eliminated. The results of operations for the three months ended March 31, 2017 may not be indicative of the results that may be expected for the year ending December 31, 2017. The December 31, 2016 consolidated balance sheet was derived from audited financial statements.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. As additional information becomes available or actual amounts become determinable, the recorded estimates are revised and reflected in operating results.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency:

Financial statement accounts expressed in foreign currencies are translated into U.S. dollars in accordance with the Foreign Currency Matters Topic of the ASC. The functional currencies of Ambac's subsidiaries are the local currencies of the country where the respective subsidiaries are based, which are also the primary operating environments in which the subsidiaries operate.

Foreign currency translation: Functional currency assets and liabilities of Ambac’s foreign subsidiaries are translated into U.S. dollars using exchange rates in effect at the balance sheet dates and the related translation adjustments, net of deferred taxes, are included as a component of Accumulated Other Comprehensive Income in Stockholders' Equity. Consolidated Statements of Total Comprehensive Income (Loss) accounts expressed in functional currencies are translated using average exchange rates.

Foreign currency transactions: The impact of non-functional currency transactions and the remeasurement of non-functional currency assets and liabilities into the respective subsidiaries' functional currency (collectively "foreign currency transactions gains/(losses)") are $6,465 and $(6,241) for the three months ended March 31, 2017 and 2016. Foreign currency transactions gains/(losses) are primarily the result of remeasuring Ambac UK's assets and liabilities denominated in currencies other than its functional currency, primarily the U.S. dollar and the Euro. The significant components of foreign currency transaction gains/(losses), including the respective classifications in the Consolidated Statement of Total Comprehensive Income, are as follows:


•	Remeasurement of loss reserves, classified in Loss and loss expenses, in the amount of $5,827 and $(10,081) for the three months ended March 31, 2017 and 2016, respectively;


•	Sales of investment securities and the unrealized gains (losses) of trading and short-term investment securities, classified in Net realized investment gains, in the amount of $1,916 and $2,783 for the three months ended March 31, 2017 and 2016, respectively;


•	Remeasurement of premium receivables, classified in Other income, in the amount of $(560) and $2,709 for the three months ended March 31, 2017 and 2016, respectively;


•	Remeasurement of credit derivative liabilities, classified in Net change in fair value of credit derivative, in the amount of $(706) and $(1,024) for the three months ended March 31, 2017 and 2016, respectively; and


•	Remeasurement of cash held, classified in Other income, in the amount of $(12) and $(628) for the three months ended March 31, 2017 and 2016, respectively.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Standards:

Effective January 1, 2017, Ambac adopted the following accounting standards:

Consolidation of Variable Interest Entities - Decision Makers

In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810) - Interests Held through Related Parties That Are under Common Control. The new guidance changes how a reporting entity that is a single decision maker for a VIE will consider its indirect interests in that VIE when determining whether the reporting entity is the primary beneficiary and should consolidate the VIE. Under previous GAAP, a single decision maker in a VIE is required to consider an indirect interest held by a related party under common control in its entirety. Under the new ASU, the single decision maker will consider the indirect interest on a proportionate basis. Adoption of this ASU did not have an impact on Ambac's financial statements.

Improvements to Employee Share-Based Payment Accounting

In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting. The objective of this ASU is to improve and simplify the accounting for employee share-based payment accounting. The amendments are as follows: (i) recognizing excess tax benefits and tax deficiencies as income tax expense, (ii) recognizing excess tax benefits regardless of whether it reduces taxes payable in the current period, (iii) classifying excess tax benefits related to share-based payments along with other income tax cash flows as an operating activity on the statement of cash flows, (iv) for purposes of accruing compensation costs, allowing companies to make an accounting policy election to either: a) estimate forfeitures or b) account for forfeitures as they occur, which Ambac elected to do upon adoption, (v) to qualify for equity classification treatment, permitting tax withholding by employees up to the maximum statutory tax rate and (vi) classifying cash paid by an employer to a taxing authority when directly withholding shares as a financing activity on the statement of cash flows. Adoption of this ASU did not have a material impact on Ambac's financial statements.

Equity Method of Accounting

In March 2016, the FASB issued ASU 2016-07, Investments-Equity Method and Joint Ventures (Topic 323) - Simplifying the Transition to the Equity Method of Accounting. This ASU eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively as if the equity method had been in effect during all previous periods that the investment had been owned. The ASU will now require that at the date an available-for-sale equity security becomes qualified for the equity method of accounting, the reporting entity will recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income. Adoption of this ASU did not have an impact on Ambac's financial statements.

Contingent Put and Call Options in Debt Instruments

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) - Contingent Put and Call Options in Debt Instruments. Previous accounting rules required that embedded derivatives be separated from the host contract in a financial instrument and accounted for separately as derivatives if certain criteria are met. One of these criteria is that the economic characteristics and risks of the embedded derivatives are not "clearly and closely related" to the host contract. The objective of the ASU is to resolve diversity in practice in assessing embedded contingent put and call options. The ASU clarifies what steps are required when assessing whether the economic characteristics and risk of put and call options are clearly and closely related to their debt host contracts. Adoption of this ASU did not have an impact on Ambac's financial statements.
