Government finance is derived revenue exports (Mining, oil and agricultural exports) as well as various forms of taxes collected by the government. In the past, foreign aid has contributed to large percentages of the budget. In 2013, Niger's government has adopted a zero-deficit budget of 1.279 trillion CFA francs ($2.53 billion) which is claimed to balance revenues and expenditures by an 11% reduction in the budget from the previous year.
