Inventories [Abstract]
Inventories	Note 4. Inventories Inventories primarily consist of raw materials, work in progress, and finished goods of manufactured products. In addition, the Company maintains an inventory of finished goods purchased for resale. Inventories are stated at lower of cost or market and consist of materials, labor, and overhead. The Company determines the cost of inventory by the first-in, first-out method. The value of inventory includes any related production overhead costs incurred in bringing the inventory to its present location and condition. The Company records the cost of excess capacity as a period expense, not as a component of capitalized inventory valuation. Management continually monitors production costs, material costs and inventory levels to determine that interim inventories are fairly stated.

The entire disclosure for inventory. This may include, but is not limited to, the basis of stating inventory, the method of determining inventory cost, the major classes of inventory, and the nature of the cost elements included in inventory. If inventory is stated above cost, accrued net losses on firm purchase commitments for inventory and losses resulting from valuing inventory at the lower-of-cost-or-market may also be included. For LIFO inventory, may disclose the amount and basis for determining the excess of replacement or current cost over stated LIFO value and the effects of a LIFO quantities liquidation that impacts net income.
