Adjusted Pre-tax Income (Loss): Adjusted pre-tax income (loss), a non-GAAP measure, is used by the Company to supplement its analysis of GAAP pre-tax income (loss). The Company uses adjusted pre-tax income (loss) as a measure of fundamental periodic financial performance. Adjusted pre-tax income (loss) adjusts GAAP pre-tax income (loss) to remove the effects of consolidating insured VIEs and gains and losses related to fair valuing insured credit derivatives, which the Company believes will reverse over time, and adds in changes in the present value of insurance claims the Company expects to pay on insured credit derivatives based on its ongoing insurance loss monitoring and loss adjustment expenses. Adjusted pre-tax income (loss) is not a substitute for and should not be viewed in isolation from GAAP pre-tax income (loss) and the Company’s definition of adjusted pre-tax income (loss) may differ from that used by other companies.Claims-paying Resources (CPR): CPR is a key measure of the resources available to National and MBIA Corp. to pay claims under their respective insurance policies. CPR consists of total financial resources and reserves calculated on a statutory basis. CPR has been a common measure used by financial guarantee insurance companies to report and compare resources and continues to be used by MBIA’s management to evaluate changes in such resources. The Company has provided CPR to allow investors and analysts to evaluate National and MBIA Corp. using the same measure that MBIA’s management uses to evaluate their resources to pay claims under their respective insurance policies. There is no directly comparable GAAP measure. Credit Impairments on Insured Derivatives: Credit impairments on insured derivatives represent actual net payments for the period plus the present value of the Company’s estimate of expected future net claim payments for such transactions, using a discount rate required by statutory accounting principles, plus loss adjustment expenses. Since the Company’s insured credit derivatives have similar terms, conditions, risks, and economic profiles to its financial guarantee insurance policies, the Company evaluates them for impairment periodically in the same way that it estimates loss and loss adjustment expenses for its financial guarantee insurance policies. Credit impairments on insured derivatives are equal to the Company’s statutory losses and loss adjustment expenses for such contracts. Credit impairments on insured derivatives may differ from the fair values recorded in the Company’s financial statements. The Company expects that the majority of its exposure written in derivative form will not be settled at fair value. The fair value of an insured derivative contract will be influenced by a variety of market and transaction-specific factors that may be unrelated to potential future claim payments. In the absence of credit impairments or the termination of derivatives at losses, the cumulative unrealized losses recorded from fair valuing insured derivatives should reverse before or at the maturity of the contracts. Contracts also may be settled prior to maturity at amounts that may be more or less than their recorded fair values. Those settlements can result in realized gains or losses, and the reversal of unrealized losses. For these reasons, the Company believes its disclosure of credit impairments on insured derivatives provides additional meaningful information to investors about potential realized losses on these contracts.
