According to Transparency International's Global Corruption Report 2009, in developing and transition countries alone, companies make payments of up to forty billion US dollars to politicians and government officials. In a survey by Control Risks and Simmons & Simmons carried out in 2007, half of the managers of multinational corporations interviewed stated that the payment of bribes added at least ten percent to their businesses' costs. The World Bank estimates that worldwide annual losses due to corruption amount to between one and four thousand billion US dollars or twelve percent of the world's gross economic output.
