Final inventory determination under the LIFO costing method is made at the end of each fiscal year based on the actual inventory levels and costs at that time. Interim LIFO determinations, including those at September 30, 2015, are based on management’s estimates of future inventory levels and costs for the balance of the current fiscal year.
