For the years ended December 31, 2017 and 2016, rent expense included in selling, general and administrative expenses for operating leases was $ 0.3 million and $0.5 million, respectively. For the years ended December 31, 2017 and 2016, rent expense included in cost of revenue for operating leases was $0.7 million and $0.4 million, respectively. In the normal course of business, we issue binding purchase orders to subcontractors and equipment suppliers. At December 31, 2017, these open purchase order commitments amount to approximately $0.5 million. The majority of services delivered and equipment received is expected to be satisfied during the first six months of 2018 at which time these commitments will be fulfilled. From time to time, we are involved in various legal matters and proceedings concerning matters arising in the ordinary course of business. We currently estimate that a material adverse effect on our financial position, results of operations and cash flows from such matters is not reasonably likely.
