V olume, as measured by metal pounds sold, increased by 73.9 million pounds, or 8%, in 201 1 compared to 2010. Metal pounds sold is provided herein as the Company believes this metric to be a consistent year over year measure of sales volume since it is not impacted by metal prices or foreign currency exchange rate changes. Metal-adjusted net sales in the North America segment increased $210.5 million, or 1 1%, principally due to favorable selling price and product mix of $164.8 million, higher sales volumes of $34.4 million, favorable foreign currency exchange rate changes of $7.8 million, principally related to the Canadian dollar , and incremental net sales of $3.5 million attributable to acquisitions. V olume, as measured by metal pounds sold, increased by 16.7 million pounds, or 6%, in 201 1 compared to 2010. The increase in sales volume is primarily attributable to volume improvement in aerial bare transmission products as well as products primarily used in specialty applications due to increased spending in the transportation sector as well as the market for oil and gas exploration coupled with volume improvement for industrial products. Metal-adjusted net sales in the Europe and Mediterranean segment increased $135.4 million, or 8%, in 201 1 compared to 2010 due to favorable selling price and product mix of $86.8 million, favorable foreign currency exchange rate changes of $71.3 million, T able of Contents
