Notes To Financial Statements [Abstract] |
Inventories | Inventories Inventories are composed of material, labor and overhead and are stated at the lower of cost or market. Costs for inventory at two of the company's manufacturing facilities have been determined using the last-in, first-out ("LIFO") method. These inventories under the LIFO method amounted to $18.9 million at June 30, 2012 and $18.6 million at December 31, 2011 and represented approximately 14.4% and 15.0% of the total inventory in each respective period. Costs for all other inventory have been determined using the first-in, first-out ("FIFO") method. The company estimates reserves for inventory obsolescence and shrinkage based on its judgment of future realization. Inventories at June 30, 2012 and December 31, 2011 are as follows:
