Supplemental Schedule Schedule 1

Radian Group Inc. and Subsidiaries-Consolidated—Exhibit O

The following schedule shows the Financial Guaranty Segment Income Statement as reported (Column 1) and adjustments (Column 2) to reflect the income statement impact of the recapture (referred to below as the clawback) of business previously ceded to the Company by one of the primary insurer customers of the financial guaranty segment. The adjusted numbers are shown in Column 3. The impact of the clawback (Column 2) reflects the clawback of business ceded to the Company in prior periods. This clawback only affected the first quarter (and, as a result, the year-to-date periods) of 2004. Accordingly, management believes that Column 3 provides useful information to investors by presenting a more meaningful basis of comparison for the Company's past and future results.

All statements in this press release that address operating performance, events or developments that we expect or anticipate may occur in the future are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 and the U.S. Private Securities Litigation Reform Act of 1995. These statements are made on the basis of management’s current views and assumptions with respect to future events. The forward-looking statements are subject to risks and uncertainties including the following: changes in general financial and political conditions, such as extended national or regional economic recessions (or expansions), changes in housing values, changes or volatility in interest rates, or other political instability; changes in investor perception of the strength of private mortgage insurers or financial guaranty providers, and risks faced by the businesses, municipalities or pools of assets covered by Radian’s insurance; the loss of significant customers with whom Radian has a concentration of its insurance in force; rising delinquencies in mortgage loans insured by Radian resulting from increased consolidation of mortgage lenders and servicers; increased severity or frequency of losses associated with certain Radian products that are riskier than traditional mortgage insurance and municipal guaranty insurance policies; material changes in persistency rates of Radian’s mortgage insurance policies; downgrades of the insurance financial-strength ratings assigned by the major ratings agencies to Radian’s operating subsidiaries; intense competition from others and from alternative products to private mortgage insurance and financial guaranty insurance; changes in the business practices of Fannie Mae and Freddie Mac; legislative and regulatory changes affecting demand for private mortgage insurance and financial guaranty insurance; changes in claims against mortgage insurance products resulting from the aging of Radian’s mortgage insurance policies; changes in Radian’s ability to maintain sufficient reinsurance capacity in an increasingly concentrated reinsurance market; vulnerability to the performance of Radian’s strategic investments; and the loss of executive officers or other key personnel. Investors are also directed to other risks discussed in documents filed by Radian with the SEC, including the factors detailed in our annual report on Form 10-K for the year ended December 31, 2003 in the section immediately preceding Part I of the report. Radian does not intend to and disclaims any duty or obligation to update or revise any forward-looking statements made in this press release to reflect new information, future events or for any other reason.
