Consolidated Explanatory Notes

1. The accompanying unaudited GAAP financial information includes the accounts of Radian, Radian Asset Assurance Limited, (RAAL) Radian Financial Products Limited, Van-American Insurance Agency, Inc. and Asset Recovery Solutions Group Inc.

These unaudited consolidated financial statements do not include all of the information and disclosures required by generally accepted accounting principles. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto, including the Report of Independent Registered Public Accounting Firm for Radian for the year ended December 31, 2006.

2. Prior year amounts have been restated to conform to current year presentation.

3. Premiums earned on credit derivative contracts of $13.7 million for the quarter ended March 31, 2008 and $18.9 million for the prior year quarter are reported in realized gain and other settlements on derivatives. This reclassification is the result of an effort by the financial guaranty industry, in consultation with the Securities and Exchange Commission, to provide consistency in disclosure of credit derivative contracts.

4. Other operating expenses were $20.5 million for the first quarter of 2008, compared to $14.1 million for the first quarter of 2007. Operating expenses for the first quarter of 2008 include an increase in employee costs, primarily severance related, as a result of Radian’s decision to exit a portion of the structured finance business and to discontinue writing insurance on CDOs.

5. The current quarter’s decrease in losses and loss adjustment expenses payable is primarily related to payments of $100.0 million pertaining to one financial guaranty transaction for which reserves of $100.0 million were established in 2007.
