6. INVENTORIES

The components of inventories are as follows:

31 December30 September
20142014
Finished goods$ 506.3 $ 493.9
Work in process 37.6 34.1
Raw materials, supplies and other 273.6 283.4
$ 817.5 $ 811.4
Less: Excess of FIFO cost over LIFO cost(107.8)(105.4)
$ 709.7 $ 706.0

First-in, first-out (FIFO) cost approximates replacement cost. Our inventories generally have a high turnover, and as a result, there is little difference between the original cost of an item and its current replacement cost.
