Raw materials and supplies353.3 384.9 
Inventories$754.4 $819.7 
All inventories are stated at the lower of cost or net realizable value. For the majority of our inventories, we use the first-in, first-out method, which is representative of our standard costs (includes materials, labor, and production overhead at normal production capacity). Remaining inventories are valued using an average-cost method.
Inventories are reviewed at least quarterly for slow-moving and potentially obsolete items using actual inventory turnover and, if necessary, are written down to estimated net realizable value.
