 themselves) may be guaranteed by the full faith and credit of the U.S. government (in the case of securities guaranteed by GNMA) or guaranteed by agencies or instrumentalities of the U.S. government (in the case of securities guaranteed by the Federal National Mortgage Association (“FNMA”) or the Federal Home Loan Mortgage Corporation (“FHLMC”)). The principal governmental guarantor of mortgage-related securities is GNMA. GNMA is a wholly-owned U.S. government corporation within the U.S. Department of Housing and Urban Development (the “Department of Housing and Urban Development” or “HUD”). GNMA is authorized to guarantee, with the full faith and credit of the U.S. government, the timely payment of principal and interest on securities issued by institutions approved by GNMA (such as savings and loan institutions, commercial banks and mortgage bankers) and backed by pools of mortgages insured by the Federal Housing Administration (the “FHA”), or guaranteed by the Department of Veterans Affairs (the “VA”). Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include FNMA and FHLMC. FNMA is a government-sponsored corporation. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers, which includes state and federally chartered savings and loan associations, mutual savings banks, commercial banks, credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. government. Instead, they are supported only by the discretionary authority of the U.S. government to purchase the agency’s obligations. FHLMC was created by Congress in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. It is a government-sponsored corporation that issues participation certificates (“PCs”), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. government. Instead, they are supported only by the discretionary authority of the U.S. government to purchase the agency’s obligations. FNMA and FHLMC also securitize RPLs. For example, in FNMA’s case, the RPLs are single-family, fixed rate reperforming loans that generally were previously
