However, because of the lack of coincident production for home market sales and U.S. sales, the current practice described above precipitates the use of constructed value more often in hyperinflationary economies than in non-hyperinflationary economies. In order to eliminate this difference, it is necessary to develop a new methodology to adjust difmers in hyperinflationary economies. The question then becomes how to calculate difmers for merchandise produced in different months. Applying the Department's normal methodology for difmer adjustments in hyperinflationary economies would yield inaccurate results because nominal manufacturing costs are different from one month to the next because of hyperinflation. A possible solution to eliminating the aberrations caused by hyperinflation in difmer calculations is to index the figures used in difmer calculations.
Indexed figures reflect the real monetary value of any prices or costs being analyzed.
Thus, indexing should not be viewed as an adjustment, but rather as a way to express prices and costs in constant monetary units which are comparable over the periods of time used in investigations and administrative reviews. Its use in hyperinflationary economies provides a method which takes into account the effects of persistent and rapid rises in prices. Therefore, during the course of antidumping proceedings involving hyperinflationary economies, which require the Department to gather monthly production costs, indexing may be performed by using the index value in effect on the date costs are calculated. Indices commonly used for commercial or financial matters should be considered in the selection of an appropriate index. Alternatively, indexing could be based on the country's exchange rate fluctuation against the U.S. dollar.
