The percent of segment sales is calculated by dividing the direct cost of goods sold for each individual segment category by the net sales for each segment category.

The Company’s management utilizes product net sales and direct and indirect cost of goods sold for each product in reviewing the financial performance of a product type.  Further allocation of Company expenses or assets, aside from amounts presented in the tables above, is not utilized in evaluating product performance, nor does such allocation occur for internal financial reporting.

Sales to the Company’s joint ventures are included in the foregoing geographic and segment information, however, sales by the Company’s joint ventures to other parties are not included.  The foregoing geographic and segment information represents only sales and cost of goods sold recognized directly by the Company.
