The volume and unit value/price indices are as compiled by countries converted to U.S. dollars and reset to 2000 = 100. Using these indices, the United Nations Statistics Division calculates the terms of trade indices (export unit value/price indices divided by the corresponding import unit value/price indices), and the indices of the purchasing power of exports (the terms of trade multiplied by the volume index of exports). Country footnotes which appear in Table 35 of this issue also apply to the country indices published in this table.
