The Federal Home Loan Mortgage Corporation (FHLMC) is a pivotal participant within the United States' secondary mortgage market. Its primary function involves acquiring residential mortgage loans, encompassing both individual single-family homes and multi-unit properties, which are originally issued by various financial institutions. In addition to these direct loan purchases, the company also allocates capital to mortgage instruments and related financial securities. FHLMC structures its extensive operations into two distinct divisions: 1. Single-family Segment: This division is dedicated to the acquisition, securitization, and guarantee of single-family home loans. It actively oversees and mitigates the credit risk associated with these mortgages, manages a portfolio of mortgage-related investments, handles securitization processes specific to single-family assets, and conducts treasury functions. This segment caters to a wide array of financial entities, including mortgage banking firms, commercial and regional banks, community banks, credit unions, housing finance agencies, savings institutions, and non-depository financial firms. 2. Multifamily Segment: This segment concentrates on the purchase, sale, securitization (notably through its specialized K and SB certificates), and guarantee of loans and securities tied to multifamily dwellings. It further expands its activities by developing and guaranteeing other securitization products, implementing various credit risk transfer strategies, and offering additional mortgage-related assurances. Its clientele is broad, comprising banks and other depository institutions, insurance providers, money managers, central banks, pension funds, state and local government entities, real estate investment trusts, brokers and dealers, and a diverse range of other lenders. Established in 1970, the Federal Home Loan Mortgage Corporation maintains its corporate headquarters in McLean, Virginia.
