During 2012 and 2011 the Company did not liquidate any LIFO inventory layers established in prior years. In the fourth quarter of 2011, as part of the Company’s aforementioned expansion into aluminum wire products and in anticipation of the start of production at the Company’s new aluminum wire plant in 2012, the Company began a new aluminum wire inventory pool that is accounted for separately from the Company’s copper wire inventory pool. The Company established this new aluminum wire pool in accordance with U.S. GAAP, which requires that new inventory items not previously present in significant quantities and having qualities significantly different from those items previously inventoried, as is the case with the physical, chemical, and cost differences between copper and aluminum metals, be accounted for separately.
