Inventory Disclosure [Abstract] |
Inventories | 5. Inventories Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value and consisted of the following (in millions):
|  | March 31, |  |  | June 30, |
|  | 2018 |  |  | 2017 |
Raw materials and work-in-progress |  | $ | 71.4 |  |  | $ | 94.7 |
Finished goods |  |  | 37.1 |  |  |  | 36.7 |
|  | $ | 108.5 |  |  | $ | 131.4 |
We record a write-down, if necessary, to reduce the carrying value of inventory to its net realizable value. The effect of these write-downs is to establish a new cost basis in the related inventory, which we do not subsequently write up. We also record a liability and charge to cost of revenue for estimated losses on inventory we are obligated to purchase from our contract manufacturers when such losses become probable from customer delays, order cancellations, or other factors.
