Significant Accounting Policies [Abstract] |
Significant Accounting Policies | Note 2: Significant Accounting Policies The Company has disclosed its significant accounting policies in "Note 2: 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, 2010. 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 the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, do not include all of the information and disclosures required by GAAP for annual periods. These 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, 2010. 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, consisting only of normal recurring adjustments, necessary for the fair statement of the Company's consolidated financial position and results of operations. 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. The results of operations for the three and nine months ended September 30, 2011 may not be indicative of the results that may be expected for the year ending December 31, 2011. The December 31, 2010 consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP for annual periods. Certain amounts have been reclassified in prior years' financial statements to conform to the current presentation. This includes the reclassification of certain investments from the previously reported line "Investments held-to-maturity, at amortized cost" to "Fixed-maturity securities held as available-for-sale, at fair value" reported under "Assets of consolidated variable interest entities" and certain investments from the previously reported line "Other investments" to "Fixed-maturity securities held as available-for-sale, at fair value" on the Company's consolidated balance sheets. These reclassifications had no impact on total revenues, expenses, assets, liabilities, or stockholders' equity for all periods presented. Consolidation The consolidated financial statements include the accounts of MBIA Inc., its wholly owned subsidiaries and all other entities in which the Company has a controlling financial interest. All material intercompany balances and transactions have been eliminated. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether an entity is a voting interest entity or a variable interest entity ("VIE"). Voting interest entities are entities in which (i) the total equity investment at risk is sufficient to enable an entity to finance its activities independently and (ii) the equity holders have the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity's activities. Voting interest entities are consolidated when the Company has a majority voting interest. VIEs are entities that lack one or more of the characteristics of a voting interest entity. The consolidation of a VIE is required if an entity has a variable interest (such as an equity or debt investment, a beneficial interest, a guarantee, a written put option or a similar obligation) and that variable interest or interests give it a controlling financial interest in the VIE. A controlling financial interest is present when an enterprise has both (a) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (b) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The enterprise with the controlling financial interest, known as the primary beneficiary, is required to consolidate the VIE. The Company consolidates all VIEs in which it is the primary beneficiary. Refer to "Note 4: Variable Interest Entities" for additional information.
