The classes of inventory as of December 31 are summarized as follows:

($ in millions)	2020		2019
Finished goods	$	90.3	$	95.8
Work in process	19.9		25.2

As of December 31, 2020 and 2019, the difference between inventories valued at LIFO and the value of that same inventory if the FIFO method had been used was not significant. The liquidation of LIFO inventory did not have a significant impact on our results of operations in any period presented.
