Government Sponsored Enterprise. A shareholder owned and operated financial institution, chartered by the federal government, that facilitates the flow of investment funds to specific economic sectors, thereby providing access to national capital markets. The activities of these private entities are not included in federal budget totals. But because of their special relationship to the government, GSEs provide detailed statements as supplementary information for budget presentation. Examples of GSEs include the Federal National Mortgage Association (Fannie Mae), the Student Loan Marketing Association (Sallie Mae), and the Federal Home Loan Mortgage Corporation (Freddie Mac).
