Inventories

Major classes of inventories are summarized as follows:



	June 30, 2018		December 31, 2017
Finished goods	$	349.4	$	301.9
Service parts	266.4		270.6
Raw materials and work in process	205.1		164.5
Total inventories	$	820.9	$	737.0

The increase in finished goods inventory was primarily attributable to increased inventory in Germany, India and Philippines to satisfy various customer projects and favorable buying opportunities. Raw materials and work in process inventory increased primarily due to a build up of inventory in the U.S. to satisfy a recent large retail customer and certain supply chain issues.
