NEW YORK, NY--(MARKET WIRE)--Dec 13, 2007 -- Attorney Advertising. Notice is hereby given that a class action has been commenced in the United States District Court for the Southern District of New York on behalf of purchasers of UBS AG ("UBS" or "the Company") (NYSE:UBS - News) common stock during the period between March 13, 2007 and December 11, 2007 (the "Class Period").

Stull, Stull & Brody has substantial experience representing employees who suffered losses from purchases of their employer's stock in their 401(k) plans. If you bought UBS stock through your UBS retirement account and have information or would like to learn more about these claims, please contact us.

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").

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." If you wish to serve as lead plaintiff, you must move the Court no later than February 11, 2008. 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 Stull, Stull & Brody, or other counsel of your choice, to serve as your counsel in this action. Stull, Stull & Brody has litigated many class actions for violations of securities laws in federal courts over the past 30 years and has obtained court approval of substantial settlements on numerous occasions. Stull, Stull & Brody maintains offices in New York and Los Angeles.
