The state's securities division sent letters last week to 10 underwriters of municipal bonds, asking them to detail their trading of credit default swaps linked to state and local government bonds they've underwritten in Massachusetts since 2003.
The other banks are: Morgan Stanley, Citigroup Inc., Deutsche Bank AG, Wells Fargo & Co., Barclays PLC, UBS AG, and both Merrill Lynch and its parent, Bank of America Corp., according to Michael Maresco, assistant secretary of state.
Bank of America will "work with Massachusetts officials to provide the information they need," said Bill Halldin, a spokesman for the Charlotte, N.C.-based company.
