From 1938 to 1968, the Federal National Mortgage Association (Fannie Mae) was the sole institution that bought mortgages from depository institutions, principally savings and loan associations, which encouraged more mortgage lending and effectively insured the value of mortgages by the US government. In 1968, Fannie Mae split into a private corporation and a publicly financed institution. The private corporation was still called Fannie Mae and its charter continued to support the purchase of mortgages from savings and loan associations and other depository institutions, but without an "explicit" insurance policy that guaranteed the value of the mortgages. The publicly financed institution was named the Government National Mortgage Association (Ginnie Mae) and it explicitly guaranteed the repayments of securities backed by mortgages made to government employees or veterans (the mortgages themselves were also guaranteed by other government organizations).
