Inventory Disclosure [Abstract]
Inventories	Inventories Inventory costs are determined using the last-in, first-out (“LIFO”) method for substantially all U.S. inventories. The current cost of the U.S. inventories under the first-in, first-out (“FIFO”) method was $487,219 and $409,034 at June 30, 2017 and December 31, 2016, respectively. These FIFO values have been reduced by approximately $81,629 and $85,113 at June 30, 2017 and December 31, 2016, respectively, to arrive at the LIFO value reported on the Condensed Consolidated Balance Sheets. The remaining inventories have been valued under the FIFO or average cost methods. All LIFO inventories are stated at the lower of cost or market. All other inventories are stated at the lower of cost or net realizable value.
