7.26 In Attachment 1 to its first written submission, Korea provides references to its exhibits to
demonstrate that for each investigation USDOC (i) identified different "models" (i.e., types of
products based on the most relevant product characteristics); (ii) calculated weighted average prices
for sales in the United States and weighted average normal values for sales in the comparison market
on a model-specific basis, for the entire period of investigation; (iii) compared the weighted average normal value of each model to the weighted average United States price for that same model; (iv)
calculated the dumping margin for an exporter by summing up the amount of dumping for each model
and then dividing it by the aggregated United States price for all models50; and in doing so (v) set to
zero all negative margins on individual models prior to summing the total amount of dumping for all
models.
