Inventories [Abstract]  
Inventory
For interim reporting, LIFO inventories are computed based on quantities as of the end of the quarter and interim changes in price levels. Changes in quantities and price levels are reflected in the interim financial statements in the period in which they occur, except in cases where LIFO inventory liquidations are expected to be reinstated by fiscal year end.
