The mortgage loans were originated or acquired by CMI and in turn sold to CMSI. A special purpose corporation, CMSI, deposited the loans into the trust, which then issued the certificates. U.S. Bank National Association will serve as trustee. For federal income tax purposes, an election will be made to treat the trust fund as one or more real estate mortgage investment conduits.
