Inventories valued using the LIFO method of inventory valuation comprised 36% and 35% of total gross inventory values as of December 31, 2012 and 2011, respectively. If the FIFO method of inventory valuation had been used, inventories would have been $243 million and $232 million higher as of December 31, 2012 and 2011, respectively. During the year ended December 31, 2012 and 2011, certain inventories accounted for on the LIFO method of accounting were reduced, which resulted in the liquidation of certain quantities carried at costs prevailing in prior years. The effect on earnings was income of $3.0 million and $0.9 million for the years ended December 31, 2012 and 2011, respectively.
