Inventory Disclosure [Abstract]  
Interim LIFO Calculations Interim LIFO CalculationsInventories are measured using the last-in, first-out (LIFO) method of valuation using an annual LIFO index. Accordingly, interim LIFO calculations must necessarily be based on management’s estimates of the components of the calculation including year-end inventory levels and the expected rate of inflation or deflation for the year. Since these estimates may be affected by factors beyond management’s control, interim results are subject to change based upon the final year-end LIFO inventory valuation.
