The complaint charges UBS and certain of its officers and directors with violations of the Securities Exchange Act of 1934. UBS is a global investment banking and securities firm which provides a range of financial services, including advisory services, underwriting, financing, market making, asset management, brokerage and retail banking on a global level.

The complaint alleges that, during the Class Period, defendants issued numerous statements regarding the Company's business and financial results. According to the complaint, these statements were materially false and misleading because they failed to disclose the Company's failure to timely write-down impaired securities containing subprime debt.

On October 30, 2007, UBS issued a press release announcing its financial results for the third quarter of 2007. In the days following this announcement, the price of UBS stock declined to as low as $49.27 per share. Then, on December 10, 2007, UBS announced writedowns of around $10 billion as a result of its subprime mortgage related positions. Following this announcement, the price of UBS stock declined to $48.78 per share, a 26% decline from the Class Period high.

Plaintiff seeks to recover damages on behalf of all purchasers of UBS common stock during the Class Period (the "Class"). The plaintiff is represented by Coughlin Stoia, which has expertise in prosecuting investor class actions and extensive experience in actions involving financial fraud.
