NEW YORK, Sept. 21, 2011 /PRNewswire/ -- Levi & Korsinsky announces that a class action lawsuit has been commenced in the United States District Court for the Northern District of Texas Dallas Division on behalf of purchasers of Penson Worldwide, Inc. ("Penson" or the "Company") (NASDAQ: PNSN) common stock from February 20, 2011 through August 4, 2011. For more information, click here: http://zlk.9nl.com/penson-worldwide. Prior to and during the Class Period, Penson derived a material part of its revenue and income from interest it received on margin loans to customers for which its customers pledged collateral in return for such loans. The complaint alleges that during the class period, defendants issued materially false and misleading statements regarding and concealed from investors that, by at least the end of 2010, a) the Company had approximately $96-97 million in receivables ("Nonaccrual Receivables") of which approximately $43 million were collateralized by illiquid securities and therefore unlikely to be collected; b) the Company's Nonaccrual Receivables were materially overstated and should have been written down at least by the end of 2010; c) as a result, the Company's reported income and EBITDA were materially overstated; and d) the Company's financial statements were not prepared in accordance with generally accepted accounting principles (GAAP). If you are a member of the class and suffered a loss in Penson stock, you have until October 24, 2011 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery is not affected by the decision whether or not to serve as a lead plaintiff.
