On June 1, 2011, the Royal Bank of Scotland ("RBS") moved to dismiss claims brought in the U.S. District Court for the Southern District of New York by investors in RBS preferred securities.  Plaintiffs allege that RBS failed to disclose its exposure to subprime mortgage-backed assets early enough.  Plaintiffs also allege that ten banks which underwrote the RBS preferred securities were negligent in preparing the offering documents.  In January, Judge Deborah Batts dismissed approximately 95 percent of the claims –  those brought by the Massachusetts Pension Reserves Investment Management Board and the Public Employees' Retirement System of Mississippi.  RBS argues in its motion that the remaining claims should be dismissed on forum non conveniens grounds and consolidated with litigation ongoing in the United Kingdom.  The ten underwriters separately moved to dismiss, arguing that plaintiffs claims are untimely and fail to adequately allege violations of Sections 11 and 12(a)(2) of the '33 Act.  RBS Memo in SupportRBS Memo to Dismiss.
