U.S. can block any major change in the Bank's governing structure. Because the U.S. exerts formal and informal influence over the Bank as a result of its vote share, control over the Presidency, and the Bank's headquarters location in Washington, D.C., friends and allies of the U.S. receive more projects with more lenient terms. World Bank Group agencies The World Bank Group consists of the International Bank for Reconstruction and Development (IBRD), established in 1944, which provides debt financing based on sovereign guarantees; the International Finance Corporation (IFC), established in 1956, which provides various forms of financing without sovereign guarantees, primarily to the private sector; the International Development Association (IDA), established in 1960, which provides concessional financing (interest-free loans or grants), usually with sovereign guarantees; the International Centre for Settlement of Investment Disputes (ICSID), established in 1965, which works with governments to reduce investment risk; the Multilateral Investment Guarantee Agency (MIGA), established in 1988, which provides insurance against certain types of risk, including political risk, primarily to the private sector. The term "World Bank" generally refers to just the IBRD and IDA, whereas the term "World Bank Group" or "WBG" is used to refer to all five institutions collectively. The World Bank Institute is the capacity development branch of the World Bank, providing learning and other capacity-building programs to member countries. The IBRD has 189 member governments, and the other institutions have between 153 and 184. The institutions of the World Bank Group are all run by a board of governors meeting once a year. Each member country appoints a governor, generally its Minister of Finance. Daily, the World Bank Group is run by a board of 25 executive directors to whom the governours have delegated certain powers. Each director represents either one country (for the largest countries), or a group of countries. Executive directors are appointed by their respective governments or the constituencies. The agencies of the World Bank are each governed by their Articles of Agreement that serves as the legal and institutional foundation for all their work. The activities of the IFC and MIGA include investment in the private sector and providing insurance, respectively. Presidency Traditionally, the Bank President has been a U.S. citizen nominated by the President of the United States, the bank's largest shareholder. The nominee is subject to confirmation by the executive directors, to serve a five-year, renewable term. Current president On 5 April
