Inventory costs include direct materials, direct labor and manufacturing overhead, or when finished goods are sourced, the cost is the amount paid to the third party. Cost of certain domestic inventories (approximately 51.8% and 54.4% of gross inventory costs at December 31, 2013 and 2012, respectively) was determined by the LIFO method; for the balance, cost was determined using the FIFO method. As of December 31, 2013 and 2012, LIFO reserves were $34.2 million and $49.8 million, respectively. The net income (loss) from continuing operations recognized by the Company related to the liquidation of LIFO-based inventories in 2013, 2012 and 2011 was $6.5 million, $3.2 million and $(2.7) million, respectively.
