The valuation of LIFO inventories is made at the end of each year based on inventory levels and costs at that time.  Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs.  Actual year-end inventory levels and costs may differ from interim LIFO inventory valuations.  At December 31, 2016 and 2015, approximately 40% of total inventories were valued using the LIFO method. The excess of current cost over LIFO cost was $61,329 at December 31, 2016 and $59,765 at December 31, 2015.
