Property, Plant, and Equipment

Property, plant and equipment are stated at cost. Depreciation is calculated primarily on the straight-line method, generally over the following estimated useful lives: land improvements – 3 to 10 years; buildings and improvements – 8 to 25 years; and vehicles and machinery and equipment – 3 to 8 years. Depreciation expense, including amortization of assets under capital lease, for the three months ended June 30, 2018 and July 1, 2017 was $2.4 million and $1.8 million, respectively.
