MBIA may have mislead investors as to the full extent of its exposure to potential losses on credit enhancements it provided to certain residential mortgage-backed securities.

This is a securities fraud class action lawsuit against MBIA which alleges MBIA and the individual defendants, Chief Executive Officer and Chief Financial Officer, violated the federal securities laws by issuing false and misleading press releases, financial statements, filings with the SEC and statements during investor conference calls.

The class action complaint alleges that, throughout the Class Period, Defendants misrepresented and/or failed to disclose the true extent of MBIA's exposure to losses stemming from MBIA's insurance of residential mortgage-backed securities ("RMBS"), including in particular its exposure to so-called "CDO-squared" securities that are backed by RMBS.

This highly risky exposure was belatedly disclosed in a series of public statements beginning on December 19, 2007 and ending on January 9, 2008, the last day of the Class Period. One analyst observed that MBIA had withheld from the public the riskiest parts of its insured portfolio, while others expressed similar dismay at MBIA's failure to apprise investors of these risks in a timely manner.
