Property, Plant and Equipment
Property, plant and equipment are recorded at cost or, in the case of assets acquired in a business combination, at fair value. Depreciation expense, which includes the amortization of assets recorded under capital leases, is computed principally using the straight-line method over the estimated useful lives of individual assets. Buildings and land improvements are depreciated based on lives varying from 10 to 40 years. All new purchases of store equipment are assigned lives varying from three to nine years. Leasehold improvements are amortized over the shorter of the lease term to which they relate, which varies from four to 25 years, or the useful life of the asset. Manufacturing plant and distribution center equipment is depreciated over lives varying from three to 15 years. Information technology assets are generally depreciated over five years. Depreciation expense was $1,703 in 2013, $1,652 in 2012 and $1,638 in 2011.
Interest costs on significant projects constructed for the Company’s own use are capitalized as part of the costs of the newly constructed facilities. Upon retirement or disposal of assets, the cost and related accumulated depreciation are removed from the balance sheet and any gain or loss is reflected in net earnings.
