Commitments and Contingencies Disclosure [Abstract] |
Commitments and contingencies | Commitments and Contingencies Class Action Litigation On March 30, 2017, the U.S. District Court for the Southern District of Texas granted the Company’s motion to dismiss the four consolidated putative securities class action lawsuits that were filed in November 2015, against the Company and certain of its officers. The lawsuits were previously consolidated into a single case, and a consolidated amended complaint had been filed. The consolidated amended complaint asserted that the Company made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. The complaint sought an award of damages in an unspecified amount on behalf of a putative class consisting of persons who purchased the Company’s common stock between October 23, 2014 and November 9, 2015, inclusive. The lead plaintiff appealed the District Court’s decision granting the motion to dismiss. On February 7, 2019, a three-judge panel of the United States Court of Appeals for the Fifth Circuit issued a unanimous opinion affirming the District Court’s judgment of dismissal in its entirety. Other Litigation The Company is subject to routine litigation and other claims that arise in the normal course of business. Management is not aware of any pending or threatened lawsuits or proceedings that are expected to have a material effect on the Company’s financial position, results of operations or liquidity. Concentrations and Credit Risk The majority of the Company’s revenue is derived from the oil and gas industry. Customers include major oilfield services companies, major integrated oil and natural gas companies, independent oil and natural gas companies, pressure pumping service companies, and state-owned national oil companies. This concentration of customers in one industry increases credit and business risks. The Company is subject to concentrations of credit risk within trade accounts receivable, as the Company does not generally require collateral as support for trade receivables. In addition, the majority of the Company’s cash is invested in accounts in two major financial institutions and balances often exceed insurable amounts.
