From the Document: "Ex-Im Bank [Export-Import Bank of the United States], the official U.S. export credit agency (ECA), provides financing and insurance to facilitate the export of U.S. goods and services to support U.S. jobs, pursuant to a renewable, general statutory charter (Export-Import Bank Act of 1945, as amended; 12 U.S.C. §§635 'et seq.'). It aims to provide support for U.S. exports when the private sector is unwilling or unable to do so and/or to counter foreign ECA financing. The Bank is demand-driven, fee-based, and backed by the U.S. government's full faith and credit."
