UBS faces new U.S. suit on auction-rate securities

BOSTON (Reuters) - New Hampshire securities regulators on Thursday sued giant Swiss bank UBS AG (UBSN.VX) for having improperly sold securities to help students finance their education.

The suit is the latest in a string of actions by U.S. regulators over auction-rate securities, which were sold as stable investments to institutions and retail investors, before the market locked up in February.
