Leases [Abstract] |
Leases of Lessee Disclosure [Text Block] | 8. Lease Obligations From time to time, the Company enters into leasing arrangements for real estate, vehicles and construction equipment, including master leasing arrangements for vehicles and construction equipment. Some of the leases entered into under these agreements met the requirements for capitalization and were recorded as capital leases, while others were treated as operating leases. As of June 30, 2018, the Company had no outstanding commitments to enter into future leases under its master lease agreements. Capital Leases The Company leases some vehicles and certain equipment under capital leases. The economic substance of the leases is a financing transaction for acquisition of the vehicles and equipment. Accordingly, these leases are included in the balance sheets in property and equipment, net of accumulated depreciation, with a corresponding amount recorded in current portion of capital lease obligations or capital lease obligations, net of current maturities, as appropriate. The capital lease assets are amortized over the life of the lease or, if shorter, the life of the leased asset, on a straight-line basis and included in depreciation expense in the statements of operations. The interest associated with capital lease obligations is included in interest expense in the statements of operations. As of June 30, 2018, the Company had approximately $3.2 million of capital lease obligations outstanding, $1.1 million of which was classified as a current liability. As of December 31, 2017, the Company had approximately $3.7 million of capital lease obligations outstanding, $1.1 million of which was classified as a current liability. As of June 30, 2018 and December 31, 2017, $3.1 million and $3.7 million, respectively, of leased assets were capitalized in construction equipment, net of accumulated depreciation. Operating Leases The Company, from time to time, leases real estate, construction equipment and office equipment under operating leases with remaining terms ranging from one to six years.
