Aggregate measure of support (AMS)

An indicator of the amount of domestic support for agriculture. As used in the Uruguay Round Agreement on Agriculture, the AMS refers to a measure of the gap between domestic and world prices multiplied by the quantity supported, plus any other commodity-specific transfers. Internal or domestic support reduction commitments in the Uruguay Round Agreement on Agriculture are expressed in terms of reductions in a total AMS covering all trade-distorting internal support measures for agriculture.
