Vasco Data says a third party may have sold products to Iran

(Reuters) - Vasco Data Security International Inc said some its products may have ended up in Iran in potential violation of U.S. sanctions. The products were sold by its European unit to a third-party distributor and may have been resold to parties in Iran, the Chicago-based company said in a statement. Shares of the data security software maker fell 9.6 percent at $24.14 in aftermarket trading. Vasco said it was conducting an internal investigation and has stopped all shipments to the distributor.
