Policy reforms in many OECD countries, driven by internal pressures and international trade commitments, led to a considerable reorientation of support towards less distorting forms. For the OECD area on average, the share of the most distorting support fell from 86% in 1986-88, to 74% in 1995-97 and 50% in 2009-11. The equivalent percentage in the European Union decreased from 92% in 1986-88 to 63% in 1995-97 and 25% in 2009-11 (but from a considerably higher support level). The SCT indicates the flexibility that policies accord to producers in their choices of product mixes. For example, a payment designated for only one specific commodity implies that in order to receive payment, a farmer must produce that commodity. Alternatively, payment may be provided for any commodity in a designated group (for example, any crop within a cereal group), or simply to any commodity without distinction.
