Inventory Disclosure [Abstract] |
Inventory Disclosure [Text Block] | 3. INVENTORIES We state our inventories at the lower of cost or net realizable value. The cost of our inventories is determined using the first-in first-out method. When we determine that our gross inventories exceed usage requirements, or if inventories become obsolete or otherwise not saleable, we record a provision for such loss as a component of our inventory accounts. Inventories consist of the following:
|  | September 30, 2023 |  | December 31, 2022
|  | (in millions)
Raw materials and work-in-progress |  | $ | 406.6 |  |  | $ | 398.9 |
Finished goods |  | 86.5 |  |  | 92.5 |
Gross inventories |  | 493.1 |  |  | 491.4 |
Inventory valuation reserves |  | (32.7) |  |  | (27.5) |
Inventories, net |  | $ | 460.4 |  |  | $ | 463.9 |
