2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

The Company has disclosed its significant accounting policies in Note 2. Basis of Presentation and Significant Accounting Policies in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. The following significant accounting policies provide an update to those included in the Company’s Annual Report on Form 10-K.

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 and nine months ended September 30, 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:

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 $19,142 and $(26,741) for the nine months ended September 30, 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 $26,556 and $(56,910) for the nine months ended September 30, 2017 and 2016, respectively;


•	Realized gain (losses) from the sale 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 $(3,780) and $22,030 for the nine months ended September 30, 2017 and 2016, respectively;


•	Remeasurement of premium receivables, classified in Other income, in the amount of $(1,960) and $8,264 for the nine months ended September 30, 2017 and 2016, respectively; and


•	Remeasurement of credit derivative liabilities, classified in Net change in fair value of credit derivative, in the amount of $(1,141) and $(929) for the nine months ended September 30, 2017 and 2016, respectively.

Reclassifications:

Reclassifications may have been made to prior years' amounts to conform to the current year's presentation.

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.

Future Application of Accounting Standards:

Equity-linked instruments with down round features

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260) and Derivatives and Hedging (Topic 815) - Accounting for Certain Financial Instruments with Down Round Features. Equity-linked instruments, such as warrants and convertible instruments may contain down round features that result in the strike price being reduced on the basis of the pricing of future equity offerings. Under the ASU, a down round feature will no longer require a freestanding equity-linked instrument (or embedded conversion option) to be classified as a liability that is remeasured at fair value through the income statement (i.e. marked-to-market). However, other features of the equity-linked instrument (or embedded conversion option) must still be evaluated to determine whether liability or equity classification is appropriate. Equity classified instruments are not marked-to-market. For earnings per share ("EPS") reporting, the ASU requires companies to recognize the effect of the down round feature only when it is triggered by treating it as a dividend and as a reduction of income available to common shareholders in basic EPS. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. We have not determined whether Ambac will early adopt this ASU. The adoption of this ASU is not expected to have a material impact on Ambac's financial statements.

Stock Compensation--Scope of Modification Accounting

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718) - Scope of Modification Accounting. The ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The current disclosure requirements in Topic 718 apply regardless of whether an entity is required to apply modification accounting under the amendments in this ASU. The amendments in this ASU are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Ambac will adopt this ASU on January 1, 2018. The adoption of this ASU is not expected to have a consequential impact on Ambac's financial statements.

Premium Amortization on Callable Debt Securities

In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for the premium on callable debt securities to the earliest call date. Under current GAAP, a reporting entity generally amortizes the premium as yield adjustment over the contractual life (i.e. maturity) of the debt security and if that debt security is called, the entity would record a loss equal to the unamortized premium. The ASU does not change the accounting for callable debt securities held at a discount, which will continue to be amortized to maturity. ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The ASU must be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We have not determined whether Ambac will early adopt this ASU and are evaluating the impact on Ambac's financial statements.

Net Periodic Pension and Postretirement Costs

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The objective of the ASU is to increase transparency in the reporting of net pension cost and net postretirement cost (collectively "net benefit cost"). The ASU requires that the service cost component of net benefit cost be reported on the same line item as other compensation costs arising from services rendered by employees. It further requires that the other components of net benefit costs (i.e. interest costs, amortization of prior service cost, etc.) be presented separately from the service cost component and outside the subtotal of income from operations, if one is presented. ASU 2017-09 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, with early adoption permitted. Ambac will adopt this ASU on January 1, 2018. The adoption of this ASU is not expected to have a consequential impact on Ambac's financial statements.

Revenue recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) that amends the accounting guidance for recognizing revenue for contracts with customers to transfer goods and contracts for the transfer of non-financial assets unless those contracts are within the scope of other accounting standards. ASU 2015-14 deferred the effective date of ASU 2014-09 to annual periods beginning after December 15, 2017, including interim periods within that reporting period. Ambac will adopt this ASU on January 1, 2018. While we have made significant progress evaluating the ASU, we note that this ASU does not apply to insurance contracts and most financial instruments and therefore is not expected to have a consequential impact on Ambac's financial statements.
