Federal Home Loan Mortgage Corporation, commonly known as Freddie Mac, is a prominent entity operating within the secondary mortgage market of the United States. Its primary function involves acquiring both single-family and multifamily residential mortgage loans originated by a diverse network of lenders. Beyond purchasing loans, the company also strategically invests in mortgage loans and various mortgage-backed securities. The organization structures its operations into two distinct divisions: Single-family and Multifamily. The Single-family segment is responsible for procuring, packaging into securities, and guaranteeing individual home loans. This division also actively manages the associated credit risk, oversees a portfolio of mortgage-related investments, conducts single-family securitization activities, and handles treasury functions. Its clientele includes a broad spectrum of financial institutions such as mortgage banking companies, commercial and regional banks, community banks, credit unions, housing finance agencies, savings institutions, and non-depository financial firms. The Multifamily segment focuses on the acquisition, sale, securitization, and guarantee of loans and securities related to multi-unit residential properties. This is achieved through mechanisms like the issuance of multifamily "K" and "SB" certificates, along with other securitization products and credit risk transfer instruments, and the provision of various mortgage-related guarantees. This segment serves an extensive array of institutional clients, including banks and other depository institutions, insurance companies, money managers, central banks, pension funds, state and local governments, real estate investment trusts (REITs), brokers and dealers, and numerous other lending entities. Founded in 1970, Federal Home Loan Mortgage Corporation is headquartered in McLean, Virginia.
