Property and Equipment
Property and equipment are stated at cost. In general, new building additions are separated into components, each with its own estimated useful life, generally five to fifty years for buildings and improvements and three to twenty years for equipment and fixtures. Depreciation and amortization expense is computed using the straight-line method over estimated useful lives or the lease term, if shorter. Leasehold improvements made after the beginning of the initial lease term are depreciated over the shorter of the estimated useful life of the asset or the remaining term of the initial lease plus any renewals that are reasonably assured at the date the leasehold improvements are made.
Repair and maintenance costs are expensed when incurred. Expenditures for remodels, refurbishments and improvements that add to or change the way an asset functions or that extend the useful life of an asset are capitalized. Assets that were removed during the remodel, refurbishment or improvement are retired. Assets classified as held for sale were not material at the end of 2013 or 2012.
The Company evaluates long-lived assets for impairment on an annual basis, when relocating or closing a facility, or when events or changes in circumstances occur that may indicate the carrying amount of the asset group, generally an individual warehouse, may not be fully recoverable. For asset groups held and used, including warehouses to be relocated, the carrying value of the asset group is considered recoverable when the estimated future undiscounted cash flows generated from the use and eventual disposition of the asset group exceed the group’s net carrying value. In the event that the carrying value is not considered recoverable, an impairment loss would be recognized for the asset group to be held and used equal to the excess of the carrying value above the estimated fair value of the asset group. For asset groups classified as held for sale (disposal group), the carrying value is compared to the disposal group’s fair value less costs to sell. The Company estimates fair value by obtaining market appraisals from third party brokers or other valuation techniques. Impairment charges, included in selling, general and administrative expenses on the consolidated statements of income, in 2013, 2012, and 2011 were immaterial.
