Inventories [Abstract] |
Inventories | (2) Inventories Inventories are valued at the lower of cost (using either the first-in, first-out ("FIFO") or average cost methods) or market. The Company evaluates and adjusts as necessary its excess and obsolescence reserve at a minimum on a quarterly basis. Excess inventories are quantities of items that exceed anticipated sales or usage for a reasonable period. The Company has guidelines for calculating provisions for excess inventories based on the number of months of inventories on hand compared to anticipated sales or usage. Management uses its judgment to forecast sales or usage and to determine what constitutes a reasonable period. Inventory cost includes material, labor and overhead. Inventories consisted of the following:

Finished goods |  |  | 25,815 |  | 18,071
Total inventories, net |  | $ | 118,976 | $ | 96,032
