Federal Home Loan Mortgage Corporation, commonly known as Freddie Mac, is a key participant in the United States' secondary mortgage market. The corporation primarily acquires residential mortgage loans, encompassing both single-family and multifamily properties, from various originating lenders. Additionally, it allocates capital into mortgage loans and a diverse array of mortgage-backed securities. Its operations are structured into two distinct segments: Single-family and Multifamily. The Single-family division is responsible for purchasing, packaging into securities, and guaranteeing loans for individual homes. It also manages the associated credit risk, oversees its portfolio of investments tied to mortgages, and handles single-family securitization activities and treasury functions. This segment serves a broad spectrum of financial entities, including mortgage banking companies, commercial, regional, and community banks, credit unions, housing finance agencies, savings institutions, and non-depository financial institutions. Conversely, the Multifamily segment focuses on the acquisition, sale, securitization, and guarantee of loans and securities for multi-unit residential dwellings. This involves issuing specialized multifamily K and SB certificates, along with other securitization and credit risk transfer products, and extending various mortgage-related guarantees. Its extensive clientele encompasses banks and other depository institutions, insurance companies, investment managers, central banks, pension funds, state and local governments, real estate investment trusts (REITs), brokers, dealers, and a wide range of lending organizations. Established in 1970, the company maintains its corporate headquarters in McLean, Virginia.
