6. | INVENTORIES
The composition of inventories at March 31, 2018, and December 31, 2017, was as follows:
(In thousands) |  | March 31, 2018 |  |  | December 31, 2017 |
Finished goods |  | $ | 128,474 |  |  | $ | 117,529 |
Raw materials |  |  | 59,263 |  |  |  | 55,219 |
Total inventories |  | $ | 187,737 |  |  | $ | 172,748 |
Inventories are priced primarily using the last-in, first-out inventory valuation method. If the first-in, first-out inventory valuation method had been used for all inventories, inventory balances would have been approximately $35,145,000 and $33,518,000 higher than reported at March 31, 2018, and December 31, 2017, respectively.
