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. Capital additions in progress were $2,014,000 and $1,607,000 at September 30, 2017 and December 31, 2016, respectively.
