Note 3 – Inventories

Inventories are valued at the lower of cost or market, with cost being determined principally by using the last-in, first-out (“LIFO”) method and market defined as replacement cost for raw materials and net realizable value for work in process and finished goods. 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 allowances 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, the cost basis of inventories three to four years old is reduced by 50% while the cost basis of inventories four to five years old is reduced by 75% and the cost basis of inventories greater than five years old is reduced to zero. Inventory is typically reviewed for obsolescence on an annual basis computed as of September 30^th, 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.
