The Company values certain of its tubular and pipe products inventory at the last-in, first-out (LIFO) method. At March 31, 2013 and December 31, 2012, approximately $43.6 million, or 15.8% of consolidated inventory, and $46.7 million, or 16.1% of consolidated inventory, respectively, was reported under the LIFO method of accounting. The cost of the remainder of the tubular and pipe products inventory is determined using a weighted average rolling first-in, first-out (FIFO) method. Inventories in our flat products segment are valued using the specific identification method. In the first quarter of 2013, the Company made an out-of-period adjustment to record previously unrecognized LIFO adjustments, which resulted in an increase to after-tax income of $1.2 million. The Company determined that this adjustment was not material to its current or prior period consolidated financial statements. If the FIFO method had been in use, inventories would have been $1.9 million lower than reported at March 31, 2013.
