average normal value per unit exceeded the weighted average export price per unit for
a sub-group, the difference was regarded as the "dumping margin" for that
comparison. When the weighted average normal value per unit was equal to or less
than the weighted average export price per unit for a sub-group, USDOC took the
view that there was no "dumping margin" for that comparison. USDOC aggregated
the results of those sub-group comparisons in which the weighted average normal
value exceeded the weighted average export price – those where the USDOC
considered there was a "dumping margin" – after multiplying the difference per unit
by the volume of export transactions in that sub-group. The results for the sub-groups
in which the weighted average normal value was equal to or less than the weighted
average export price were treated as zero for purposes of this aggregation, because
there was, according to USDOC, no "dumping margin" for those sub-groups. Finally,
USDOC divided the result of this aggregation by the value of all export transactions
of the product under investigation (including the value of export transactions in the
sub-groups that were not included in the aggregation). In this way, USDOC obtained
an "overall margin of dumping", for each exporter or producer, for the product under
investigation (that is, softwood lumber from Canada)...
