Inventories are stated at the lower of cost, using the last-in, first out (“LIFO”) method, or market. The Company maintains two inventory pools for LIFO purposes. As permitted by U.S. generally accepted accounting principles, the Company maintains its inventory costs and cost of goods sold on a first-in, first-out (“FIFO”) basis and makes a monthly adjustment to adjust total inventory and cost of goods sold from FIFO to LIFO. The Company applies the lower of cost or market (“LCM”) test by comparing the LIFO cost of its raw materials, work-in-process and finished goods inventories to estimated market values, which are based primarily upon the most recent quoted market price of copper and other material prices as of the end of each reporting period. The Company performs a lower of cost or market calculation quarterly. As of June 30, 2020, no LCM adjustment was required. However, decreases in copper and other material prices could necessitate establishing an LCM reserve in future periods. Additionally, future reductions in the quantity of inventory on hand could cause copper or other raw materials that are carried in inventory at costs different from the cost of copper and other raw materials in the period in which the reduction occurs to be included in costs of goods sold for that period at the different price.

In the second quarter of 2020, LIFO adjustments were recorded, increasing cost of sales by $0.7 million, versus LIFO adjustments decreasing cost of sales by $3.3 million in the second quarter of 2019. In the first six months of 2020, LIFO adjustments were recorded, decreasing cost of sales by $8.9 million, versus LIFO adjustments increasing cost of sales by $0.5 million in the first six months of 2019.
