Commitments and Contingencies Disclosure [Abstract]

Purchase Commitments

As of September 30, 2018, we had outstanding purchase commitments to a number of suppliers totaling $5.8 million, net of deposits previously made, related primarily to the construction of drilling rigs. All of these commitments relate to equipment currently scheduled for delivery in 2018.

Lease Commitments

We have several non-cancelable operating and capital leases primarily for the rental of office space, certain equipment and vehicles. Future minimum lease payments under operating and capital lease commitments, with lease terms in excess of one year subsequent to September 30, 2018, were as follows:



(in thousands)

2019	1,085

Thereafter	401
	$	3,367

As of September 30, 2018, property, plant and equipment on our balance sheet included $1.3 million of equipment under capital lease, which is net of $0.6 million of accumulated amortization. As of December 31, 2017, property, plant and equipment in our balance sheet included $1.3 million of equipment under capital lease, net of $0.5 million of accumulated amortization. This equipment consists entirely of vehicles used in our operations.

Contingencies

We may be the subject of lawsuits and claims arising in the ordinary course of business from time to time. Management cannot predict the ultimate outcome of such lawsuits and claims. While lawsuits and claims are asserted for amounts that may be material should an unfavorable outcome be the result, management does not currently expect that the outcome of any of these known legal proceedings or claims will have a material adverse effect on our financial position or results of operations.
