Adjusted Book Value: Adjusted Book Value (ABV), a non-GAAP measure, is used by the Company to supplement its analysis of GAAP book value. The Company uses ABV as a measure of fundamental value and considers the change in ABV an important measure of periodic financial performance. ABV adjusts GAAP book value to remove the impact of certain items which the Company believes will reverse over time, as well as to add in the impact of certain items which the Company believes will be realized in GAAP book value in future periods. The Company has limited such adjustments to those items that it deems to be important to fundamental value and performance and which the likelihood and amount can be reasonably estimated. ABV assumes no new business activity. The Company has presented ABV to allow investors and analysts to evaluate the Company using the same measure that MBIA’s management regularly uses to measure financial performance. ABV is not a substitute for and should not be viewed in isolation from GAAP book value. ABV is calculated on a consolidated basis and a segment basis. ABV by segment provides information about each segment’s contribution to consolidated ABV and is calculated using the same formula. ABV per share represents that amount of ABV allocated to each common share outstanding at the measurement date.
