Inventories consisted of the following:
As of December 31, |
(in thousands) |  | 2016 |  |  | 2015 |
Unprocessed |  | $ | 203,256 |  |  | $ | 163,942 |
Processed and finished |  |  | 51,270 |  |  |  | 42,703 |
Totals |  | $ | 254,526 |  |  | $ | 206,645 |
During 2016 and 2015, the Company recorded $1.5 million and $3.3 million, respectively of LIFO income as a result of decreased metals pricing during 2016 and 2015. The LIFO income increased the Company’s inventory balance and decreased its cost of materials sold. If the FIFO method had been in use, inventories would have been $8.0 million and $6.6 million lower than reported at December 31, 2016 and 2015, respectively.
