Cost of inventories for certain materials are determined using the last-in-first-out (LIFO) method and totaled approximately $25.2 million at September 30, 2013 and $30.2 million at December 31, 2012. An actual valuation of inventories under the LIFO method can be made only at the end of the year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations must be based on management’s estimates of expected year-end inventory levels and costs. Because these estimates are subject to change and may be different than the actual inventory levels and costs at the end of the year, interim results are subject to the final year-end LIFO inventory valuation. During the three and nine month periods ended September 30, 2013, the net change in LIFO inventories resulted in a less than $.1 million benefit to and $.2 million charge to Income before income taxes, respectively. During the three and nine month periods ended September 30, 2012, the net change in LIFO inventories resulted in a benefit of $.2 million and a $.2 million charge to Income before income taxes, respectively. Noncurrent inventory is included in Other assets on the Consolidated Balance Sheets.
