Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION

Ambac has two reportable segments, as follows: (i) Financial Guarantee, which provides financial guarantees (including credit derivatives) for public finance, structured finance and other obligations; and (ii) Financial Services, which provides investment agreements, funding conduits, interest rate and currency swaps, principally to clients of the financial guarantee business. Ambac’s reportable segments were strategic business units that offer different products and services. They are managed separately because each business required different marketing strategies, personnel skill sets and technology.

Ambac Assurance guarantees the swap and investment agreement obligations of its Financial Services affiliates. Additionally, Ambac Assurance provides loans to the Financial Services businesses. Inter-segment revenues include the premiums and investment income earned under those agreements. Such premiums are determined as if they were premiums paid by third parties, that is, at current market prices.

Information provided below for “Corporate and Other” primarily relates to (i) amounts received by Ambac under the Mediation Agreement dated September 21, 2011 (as more fully described in Note 1 to the Consolidated Financial Statements in Part II, Item 8 of Ambac’s 2013 Form 10-K); and (ii) other corporate activities, including interest income on the investment portfolio, including accrual of interest on the junior surplus notes issued by the Segregated Account. Corporate and Other intersegment revenue relates to receipts under the Mediation Agreement. The following table is a summary of financial information by reportable segment for the affected periods:
