INVENTORIES

Inventories are stated at the lower of cost, determined by the last-in, first-out (LIFO) method, or market.

Inventories consist of the following:

Raw materials	$	31,846		$	28,283

LIFO pools are established at the end of each fiscal year. During the first three quarters of every year, LIFO calculations are based on the inventory levels and costs at that time. Accordingly, interim LIFO balances will fluctuate up and down in tandem with inventory levels and costs.

During the first six months of 2015, the Company did not liquidate any LIFO inventory layers established in prior years. A LIFO adjustment was recorded decreasing cost of sales by $1.5 million during the second quarter of 2015 and by $10.8 million in the first six months. During the first six months of 2014, the Company liquidated a portion of the LIFO inventory layer in the aluminum wire pool established in prior years. This liquidation had an insignificant effect on the net income of the Company. During 2014, LIFO adjustments were recorded decreasing cost of sales by $1.9 million in the second quarter and by $6.8 million in the first six months.
