The AoA prohibits export subsidies unless the subsidies are specified in a member's schedule of commitments. Where they are listed, the agreement requires WTO members to cut both the amount of money they spend on export subsidies and the quantities of exports that receive subsidies. Taking averages for 1986-90 as the base level, developed countries agreed to cut the value of export subsidies by 36% over six years and developing countries by 24% over ten years starting in 1995. Developed countries also agreed to reduce the quantities of subsidized exports by 21% over the six years (14% over 10 years for developing countries). Least-developed countries were not required to make any cuts. During the six-year implementation period, developing countries were allowed under certain conditions to use subsidies to reduce the costs of marketing and transporting for exports.
