Inventories
Note 3 – Inventories
Inventories are valued at the lower of cost or net realizable value with cost being determined under the first in, first out method and net realizable value defined as the estimated selling price of goods less reasonable costs of completion and delivery. Appropriate consideration is given to obsolescence, excessive levels, deterioration, possible alternative uses and other factors in determining net realizable value. The cost of work in process and finished goods includes materials, direct labor, variable costs and overhead. The Company evaluates the need to record inventory adjustments on all inventories, including raw material, work in process, finished goods, spare parts and used equipment. Used equipment acquired by the Company on
trade-in
from customers is carried at estimated net realizable value. Unless specific circumstances warrant different treatment regarding inventory obsolescence, an allowance is established to reduce the cost basis of inventories
three
to four years old by 50%, the cost basis of inventories
four
to five years old by 75%, and the cost basis of inventories greater than five years old to zero. Inventory is typically reviewed for obsolescence on an annual basis computed as of September 30, the Company’s fiscal year end. If significant known changes in trends, technology or other specific circumstances that warrant consideration occur during the year, then the impact on obsolescence is considered at that time.
