latter case, trade in electricity reported by the trading partner is used as the basis of the estimates. For example, U.S. imports of electricity from Canada are imputed from records of Canadian exports of electricity to the United States.
             Many countries report a portion of their trade as being with regions or aggregated groups of countries rather than with specific trading partners. For example, Argentina's exports of calf leather may be recorded as destined for "E.E.C. n.e.s." ("not elsewhere specified"), rather than to a specific E.E.C. member (or members) . In other cases, a product may be recorded as destined for "Areas n.e.s." or "Not Specified", without identification of a broad region of destination.
             The comparability of the U.N. data is improved by identifying these anonymous trading partners and reallocating the exporter's trade to them. In the example above, Argentina's calf leather exports to "E.E.C. n.e.s." are apportioned to each of the E.E.C.'s member countries
