Commitments And Contingencies Disclosure [Abstract] |
Commitments and Contingencies | 11. Commitments and Contingencies As of June 30, 2017, the Company maintained letters of credit in the aggregate amount of $55.2 million for the benefit of various insurance companies as collateral for retrospective premiums and retained losses which could become payable under the terms of the underlying insurance contracts. These letters of credit expire annually at various times during the year and are typically renewed. As of June 30, 2017, no amounts had been drawn under the letters of credit. As of June 30, 2017, the Company had commitments to purchase approximately $160 million of major equipment for its drilling, pressure pumping and oilfield rental tools businesses. The Company’s pressure pumping business has entered into agreements to purchase minimum quantities of proppants and chemicals from certain vendors. These agreements expire in 2017, 2018, 2021 and 2041. As of June 30, 2017, the remaining obligation under these agreements was approximately $90.3 million, of which approximately $3.4 million and $9.5 million relates to purchases required during the remainder of 2017 and 2018, respectively. In the event the required minimum quantities are not purchased during certain periods, the Company could be required to make a liquidated damages payment to the respective vendor for any shortfall. The Company is party to various legal proceedings arising in the normal course of its business. The Company does not believe that the outcome of these proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition, results of operations or cash flows.
