Property, Plant, and Equipment
Property, plant, and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over estimated useful lives of 10 to 40 years for buildings, 3 to 10 years for machinery and equipment, and 10 to 20 years, not to exceed the lease term, for leasehold improvements. Tools, dies, and molds are amortized using the straight-line method over 3 years. Estimated useful lives are periodically reviewed and, where appropriate, changes are made prospectively. The carrying value of property, plant, and equipment is reviewed when events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Any potential impairment identified is assessed by evaluating the operating performance and future undiscounted cash flows of the underlying assets. When property is sold or retired, the cost of the property and the related accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is included in the results of operations.
