Inventory Disclosure [Abstract] |
Inventories | Inventories Inventories are valued at the lower of cost or market. Effective October 1, 2015, the Company changed its method for inventory costing from the last in, first out (LIFO) cost method to the first in, first out (FIFO) cost method for all operations that were using the LIFO cost method. This change in accounting method was deemed preferable because this change causes inventory to be valued on a consistent basis throughout the entire Company and on a more comparable basis with industry peer companies. This change in accounting method was completed in accordance with Accounting Standards Codification (ASC) 250 Accounting changes and error corrections, and all periods presented have been retrospectively adjusted to reflect the period-specific effects of applying the new accounting principle. The following table summarizes the effect of this accounting change on the Company’s consolidated statements of operations for the quarter ended March 31, 2015:
| Quarter Ended March 31, 2015
