7.       INVENTORIES

The components of inventories are as follows:

 Inventories at FIFO Cost       
 Finished goods$ 522.6 $ 477.3  
 Work in process  30.8   29.9  
 Raw materials, supplies and other  245.5   258.8  
    798.9   766.0  
 Less: Excess of FIFO cost over LIFO cost  (99.4)   (95.8)  
  $ 699.5 $ 670.2  

FIFO cost approximates replacement cost. Our inventories have a high turnover, and as a result, there is little difference between the original cost of an item and its current replacement cost.
