Radian Reports Third Quarter Net Income of $112 Million

PHILADELPHIA, Oct. 18 /PRNewswire-FirstCall/ -- Radian Group Inc. today reported results for the quarter ended September 30, 2006, with net income of $112 million and diluted net income per share of $1.36. Book value per share at September 30, 2006, was $49.11, an increase of 14% from a year earlier.

For the nine months ended September 30, 2006, Radian reported net income of $424 million, up from a year earlier, and diluted net income per share of $5.12, an increase of 10.1%.

"While our results for the quarter were affected by additions to loss reserves for our mortgage insurance business, I am pleased with the strong performance we achieved in the first nine months of the year, with double- digit increases in diluted earnings per share and book value per share," said Chief Executive Officer S.A. Ibrahim. "We remain disciplined in our approach to risk and capital management, and are focused on delivering long-term value."

Mr. Ibrahim said the addition to loss reserves for the mortgage insurance business was attributable to several factors, including new delinquencies, an aging of existing delinquencies, and an increase in severity due primarily to larger average loan balances.

Regarding the mortgage insurance business, Radian said it continued to experience good flow volume, which is benefiting from positive cyclical trends, including stable interest rates and increased MI penetration. The company added that it did less structured business in the quarter, reflecting market conditions and the tight-spread environment.

The company's financial guaranty business continued to perform well in a difficult environment, further demonstrating the viability of its double-A franchise.

In the Financial Services segment both C-BASS and Sherman continued to be important and steady contributors to Radian's results. The key financial highlights of the quarter and nine months ended September 30, 2006, are as follows:

All statements made in this news release that address 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, as well as Radian's prospects as a whole, 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, population trends and changes in household formation patterns, changes in unemployment rates, or changes or volatility in interest rates; changes in investor perception of the strength of private mortgage insurers or financial guaranty providers; risks faced by the businesses, municipalities or pools of assets covered by Radian's insurance; the loss of a customer with whom Radian has a concentration of its insurance in force; increased severity or frequency of losses associated with certain Radian products that are riskier than traditional mortgage insurance and financial guaranty insurance policies; material changes in persistency rates of Radian's mortgage insurance policies; changes in Radian's credit ratings or the insurance financial- strength ratings assigned by the major ratings agencies to Radian's operating subsidiaries; heightened competition from other insurance providers and from alternative products to private mortgage insurance and financial guaranty insurance; changes in the charters or business practices of Fannie Mae and Freddie Mac; the application of federal or state consumer, lending, insurance and other applicable laws and regulations, or unfavorable changes in these laws and regulations or the way they are interpreted, including: (i) the possibility of private lawsuits or investigations by state insurance departments and state attorneys general alleging that services offered by the mortgage insurance industry, such as captive reinsurance, pool insurance and contract underwriting, are violative of the Real Estate Settlement Procedures Act and/or similar state regulations (particularly in light of inquiries that we and other mortgage insurers have received from the New York Insurance Department and public reports that other state insurance departments are investigating or planning to investigate captive reinsurance arrangements used in the mortgage insurance industry) or (ii) legislative and regulatory changes affecting demand for private mortgage insurance or financial guaranty insurance; the possibility that we may fail to estimate accurately the likelihood, magnitude and timing of losses in connection with establishing loss reserves for our mortgage insurance or financial guaranty businesses or to estimate accurately the fair value amounts of derivative financial guaranty contracts in determining gains and losses on these contracts; changes in accounting guidance from the SEC or the Financial Accounting Standards Board regarding income recognition and the treatment of loss reserves in the mortgage insurance or financial guaranty industries; changes in claims against mortgage insurance products resulting from the aging of Radian's mortgage insurance policies; vulnerability to the performance of Radian's strategic investments; changes in the availability of affordable or adequate reinsurance for our non-prime risk; and international expansion of our mortgage insurance and financial guaranty businesses into new markets and risks associated with our international business activities. Radian does not intend to, and disclaims any duty or obligation to, update or revise any forward-looking statements made in this news release to reflect new information, future events or for any other reason.
