The lawsuit alleges that defendants made false and/or misleading statements and/or failed to disclose that: (1) VASCO's products were illegally sold to parties in Iran in violation of federal laws banning such transactions; (2) VASCO lacked sufficient internal controls; and (3) as a result of the foregoing, VASCO's public statements were materially false and misleading at all relevant times. On July 21, 2015, after the market closed for trading, VASCO filed a Form 8-K with the SEC revealing "that certain of its products which were sold by a VASCO European subsidiary to a third party distributor may have been resold by the distributor to parties in Iran, potentially including parties" governed by U.S. economic sanctions. The suit claims investors were damaged when this adverse news entered the market. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than September 28, 2015.
