Approximately 84% and 87% of our total inventory in 2017 and 2016, respectively, were valued on a LIFO (last-in, first-out) basis.

The distinction between the use of different methods of inventory valuation is primarily based on geographical locations and/or legal entities. The following table summarizes the amount of inventory that is not accounted for under the LIFO method.

	December 31, 2017		December 31, 2016
U.S. locations	$	6.5	$	4.2
Canada locations		2.2		1.9
Total	$	8.7	$	6.1

Our Canadian locations use the FIFO method of inventory valuation (or other methods which closely approximate the FIFO method) primarily because the LIFO method is not permitted for local tax and/or statutory reporting purposes. In these situations, a conversion to LIFO would be highly complex and involve excessive cost and effort to achieve under local tax and/or statutory reporting requirements. U.S. locations that use the FIFO method of inventory valuation primarily represent certain finished goods sourced from third party suppliers.
