    The African Development Bank (AFDB) was established in 1964 and, by charter amendment, opened its membership to non-African countries in

    1982. Its mandate is to contribute to the economic development and social progress of its regional members. Bank members total 77, including 53 African countries and 24 nonregional countries. With the September 1999 ratification of the agreement on the fifth general capital increase, Bank ownership is 60 percent African and 40 percent nonregional.

    The African Development Fund (AFDF), the concessional lending affiliate, was established in 1973 to complement AFDB operations by providing concessional financing for high-priority development projects in the poorest African countries. The Fund's membership consists of 25 nonregional member countries, South Africa, and AFDB, which represents its African members and is allocated half of the votes.

    In February 2003, security concerns resulted in AFDB headquarters temporarily relocating to Tunis, Tunisia.
