Inventories are recognized at the lower of cost of purchase or production cost, or the net realizable value. The cost of purchase or production cost is calculated using the weighted average cost method. The net realizable value corresponds to the estimated sales proceeds less the estimated cost of completion.
Material costs incurred before the start of installation of an elevator or escalator are recognized as inventory for customer contracts at the lower of production cost or the net realizable value. With the start of revenue recognition, inventory for customer contracts is transferred to contract balances.
Inventory allowances are recognized for slow-moving stock. Technically obsolete items are written off.
