Organization, Consolidation and Presentation of Financial Statements [Abstract]
Inventory Policy	The Company primarily uses the last-in, first-out (LIFO) method of valuing inventory. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs are subject to the final year-end LIFO inventory valuation. In addition, interim inventory levels include management’s estimates of annual inventory losses due to shrinkage and other factors. The final year-end valuation of inventory is based on an annual physical inventory count performed during the fourth quarter. For further information on inventory valuations and other matters, refer to the consolidated financial statements and footnotes thereto included in the Company’s Form 10-K for the year ended December 31, 2013.

Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.
