	The 2010 budget of the ICRC amounts to about 1156 million Swiss francs. All payments to the ICRC are voluntary and are received as donations based on two types of appeals issued by the Committee: an annual "Headquarters Appeal" to cover its internal costs and "Emergency Appeals" for its individual missions. The total budget for 2009 consists of about 996.9 million Swiss Francs (85% of the total) for field work and 168.6 million Swiss Francs (15%) for internal costs. In 2009, the budget for field work increased by 6.9% and the internal budget by 4.4% compared to 2008, primarily due to above-average increases in the number and scope of its missions in Africa.
