Inventory Disclosure [Abstract] |
Inventories, net | 6. Inventories, net Inventories consist primarily of engines and parts. Engines are valued at the lower of cost, plus estimated freight-in, as determined by specific serial number identification, or market value. Parts are valued at the lower of cost (first-in, first-out) or market value. When necessary, the Company writes down inventory for an estimated amount equal to the difference between the cost of the inventory and the estimated realizable value. Additionally, an inventory reserve is recorded based upon the Company’s estimation of future demand for the quantity of inventory on hand. In determining an estimate of future demand, multiple factors are taken into consideration, including (i) customer purchase orders and customer forecasted demand, (ii) historical sales/usage for each inventory item, and (iii) utilization within a current or anticipated future power system. Inventory consisted of the following as of:
