The World Bank and four regional development banks (Inter-American Bank, European Bank for Reconstruction and Development, Asian Development Bank and African Development Bank) have agreed to blacklist any company that one of the banks finds guilty of corruption. Typically, companies found guilty of corruption by one of the development banks will be debarred so they will not be able to bid on projects for a given number of years and sometimes permanently. This new policy is expected to take effect from 1 May 2010. It will affect new and not pre-1 May debarments.
