The Financial Industry Regulatory Authority (FINRA) has fined Credit Suisse Securities (USA) LLC $4.5 million, and Merrill Lynch $3 million. The fines arise out of FINRA’s findings that the firms misrepresented historical delinquency rates in connection with the residential subprime mortgage securitizations (RMBS) that the firms underwrote and sold. Upon learning of the errors, Merrill Lynch posted the corrected historical delinquency rates on its website, but Credit Suisse did not.
