On November 2, 2011, Capital Ventures, an investor group, sued UBS in Massachusetts federal court, claiming that UBS Securities misled it into purchasing securities backed by faulty mortgage loans by misrepresenting the quality of those loans in the offering materials.  Capital Ventures alleges it purchased more than $109 million worth of mortgage-backed securities from UBS over six separate transactions and that a significant portion of that value has been lost as the mortgages underlying the securities have defaulted.  Capital Ventures alleges claims under the Massachusetts Uniform Securities Act.  Complaint.
