Since 1999, country risk categories have been harmonized by the Arrangement and minimum premium rates have been allocated to the various risk categories. This is intended to ensure that competition takes place via pricing and the quality of the goods exported, and not in terms of how much support a state provides for its exporters. The Arrangement does not extend to exports of agricultural commodities or military equipment. A recent decision at the World Trade Organization (WTO) indicates that the use of officially supported export credits in agriculture is bound by WTO members' commitments with respect to subsidised agricultural exports (see the WTO Appellate Body decision on the Brazil-US cotton case as it relates to the General Sales Manager (GSM) 102 and 103 programs and other US agricultural export credits, summarized here).
