Inventory Disclosure [Text Block] | 5. Inventories : Inventories consisted of the following:
As of December 31, |
(in thousands) |  | 2018 |  |  | 2017 |
Unprocessed |  | $ | 306,953 |  |  | $ | 225,187 |
Processed and finished |  |  | 61,785 |  |  |  | 50,120 |
Totals |  | $ | 368,738 |  |  | $ | 275,307 |
During 2018 and 2017, the Company recorded $8.4 million and $2.7 million, respectively, of LIFO expense as a result of increased metals pricing during 2018 and 2017. The LIFO expense decreased the Company’s inventory balance and increased its cost of materials sold. If the FIFO method had been in use, inventories would have been $3.1 million higher and $5.3 million lower than reported at December 31, 2018 and 2017, respectively.
