(NYSE:RDN) ("Radian" or the "Company") from January 23, 2007 through July 31, 2007, inclusive (the "Class Period").

The Complaint charges Radian and certain of its officers and directors with violations of the Securities Exchange Act of 1934. Radian is a global credit risk management company. More specifically, the Complaint alleges that the Company failed to disclose and misrepresented the following material adverse facts which were known to defendants or recklessly disregarded by them: (1) that the Company`s investment in C-BASS was materially impaired due to increasing margin calls; (2) that C-BASS` investments were, at an alarming rate, substantially declining in value; (3) that the Company overstated its financial results by failing to properly and timely value its declining investment in C-BASS; (4) that the Company`s financial statements were not prepared in accordance with Generally Accepted Accounting Principles; and (5) that, as a result of the foregoing, the Company`s financial statements were materially false and misleading at all relevant times.

C-BASS is a mortgage credit joint venture between Defendant Radian and MGIC Investment Corporation ("MGIC"). C-BASS was reportedly worth $1 billion, and Radian and MGIC each possessed a 46 percent equity stake in the company worth approximately $466 million each. In February 2007, Radian and MGIC announced that they had agreed to merge and form a new company entitled MGIC Radian Financial Group, Inc. pursuant to a stock-for-stock transaction, which was valued at approximately $4.9 billion. It was reported that the two companies planned to sell down their combined stake in C-BASS by 50 percent at the time of the merger, which was scheduled to close late in the third quarter or fourth quarter of 2007.

On July 30, 2007, after the close of the market, Radian shocked investors when it disclosed that the value of its investment in C-BASS was materially impaired. The Company admitted that since February 2007, the market for subprime mortgages had experienced significant turmoil, with market dislocations recently accelerating and deteriorating. The Company stated that its investment in C-BASS was approximately $518 million at the time, and that impairment charges, the level of which could not be determined, could cost Radian its entire investment in C-BASS.

Then on July 31, 2007, before the market opened, C-BASS disclosed that due to the "frequency and magnitude" of margin calls, its liquidity was materially affected. C-BASS revealed that during the first 6 months of 2007, it had met $290 million in lender margin calls, and since that time it was forced to meet an additional $260 million of margin calls. As such, C-BASS stated that it was exploring strategic options in an attempt to mitigate its liquidity risk. On this news, Radian`s shares fell $6.49 per share, or over 16 percent, to close on July 31, 2007 at $33.71 per share, on unusually heavy trading volume. The following day, the Company`s shares fell an additional $6.20 per share, or over 18 percent, to close on August 1, 2007 at $27.51 per share, again on heavy trading volume.

If you are a member of the class described above, you may, not later than October 15, 2007, move the Court to serve as lead plaintiff of the class, if you so choose. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member`s claim is typical of the claims of other class members, and that the class member will adequately represent the class. Under certain circumstances, one or more class members may together serve as "lead plaintiff." Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. You may retain Schiffrin Barroway Topaz & Kessler or other counsel of your choice, to serve as your counsel in this action.
