This report shows in tabular form how much the Administration requested and how much Congress appropriated during the past 11 years for U.S. payments to the multilateral development banks (MDBs). It also provides a brief description of the MDBs and the ways they fund their operations. It will be updated periodically. Three companion reports provide further information on the MDBs. See CRS Report RS20793, Multilateral Development Banks: Basic Background, CRS Report RS20791, Multilateral Development Banks: Procedures for U.S. Participation, and CRS Report RS22134 International Financial Institutions: Funding U.S. Participation.
