Inventories Inventories
Inventories are valued at the lower of cost or net realizable value. Cost is determined by the first-in, first-out (“FIFO”) method. We establish an allowance for excess and obsolete inventories based on product line changes, the feasibility of substituting parts and the need for supply and replacement parts.
The components of inventories and related changes in the allowance for excess and obsolete inventories account are as follows:
