Federal Home Loan Mortgage Corporation, commonly known as Freddie Mac, is a key participant in the United States' secondary mortgage market. Its primary activities involve acquiring residential mortgage loans, encompassing both single-family homes and multi-unit properties, from a variety of lenders. Furthermore, the corporation allocates capital to mortgage loans and related securities. The company's operations are divided into two main divisions: Single-family and Multifamily. The Single-family division is tasked with the procurement, securitization, and assurance of loans for individual residences. It also manages the inherent credit risk associated with these mortgages, oversees its portfolio of mortgage-linked investments, directs single-family securitization processes, and performs treasury functions. This segment provides services to a wide array of clients, including mortgage banking firms, commercial and regional banks, community banks, credit unions, housing finance agencies, savings institutions, and other non-depository financial entities. Conversely, the Multifamily division concentrates on the acquisition, disposition, securitization, and guaranteeing of loans and securities pertaining to multi-unit properties, notably through its K and SB certificates. It also issues and backs other securitization products, facilitates various credit risk transfer mechanisms, and extends additional mortgage-related guarantees. Its diverse clientele includes banks and other depository institutions, insurance companies, asset management firms, central banks, pension funds, state and local government entities, real estate investment trusts, brokers and dealers, and a broad spectrum of lending organizations. The corporation was founded in 1970 and is based in McLean, Virginia.
