The Asian Development Bank (ADB) is a regional development bank established on 19 December 1966, which is headquartered in 6 ADB Avenue, Mandaluyong, Metro Manila 1550, Philippines. The bank also maintains 31 field offices around the world to promote social and economic development in Asia. The bank admits the members of the UN Economic and Social Commission for Asia and the Pacific (UNESCAP, formerly the Economic Commission for Asia and the Far East or ECAFE), and non-regional developed countries. Starting with 31 members at its establishment, ADB now has 68 members.
The ADB was modeled closely on the World Bank and has a similar weighted voting system, where votes are distributed in proportion with members' capital subscriptions. ADB releases an annual report that summarizes its operations, budget, and other materials for review by the public.
