Property, plant, and equipment are recorded at cost, unless obtained through acquisition, then assets are recorded at estimated fair value at the date of acquisition. Depreciation is provided on a straight-line method over the estimated useful lives of the assets. The carrying amount of long-lived assets is evaluated annually to determine if an adjustment to the depreciation period or to the unamortized balance is warranted. Amounts invested in capital additions in progress were $2,314,000 and $1,607,000 at March 31, 2017 and December 31, 2016, respectively. At March 31, 2017 and December 31, 2016, purchase commitments for capital expenditures in progress were $645,000 and $616,000, respectively.
