Inventory Disclosure [Abstract]

INVENTORIES

INVENTORIES

Inventories were stated at the lower of cost or net realizable value, with cost primarily determined on the last-in, first-out (LIFO) method. Management believes that the use of LIFO results in a better matching of costs and revenues.

The following table summarizes the extent to which the Company's Inventories use the LIFO cost method, and presents the effect on inventories had the Company used the first-in, first-out (FIFO) inventory valuation method.

	2019				2018				2017
Percentage of total inventories on LIFO	72		%		72		%		71		%
Excess of FIFO over LIFO	$	339.8			$	377.1			$	288.2

The Company recorded a reserve for obsolescence of $115.4 million, $105.9 million and $103.7 million at December 31, 2019, 2018 and 2017, respectively, to reduce Inventories to their estimated net realizable value.
