Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Environmental The Company is subject to various federal, state and local environmental laws and regulations that establish standards and requirements for protection of the environment. The Company cannot predict the future impact of such standards and requirements which are subject to change and can have retroactive effectiveness. The Company continues to monitor the status of these laws and regulations. Currently, the Company has not been fined, cited or notified of any environmental violations that would have a material adverse effect upon its financial position, liquidity or capital resources. However, management does recognize that by the very nature of its business, material costs could be incurred to maintain compliance. The amount of such future expenditures is not determinable due to several factors, including the unknown magnitude of possible regulation or liabilities, the unknown timing and extent of the corrective actions which may be required, the determination of the Company's liability in proportion to other responsible parties and the extent to which such expenditures are recoverable from insurance or indemnification. Litigation FASB ASC 450 - "Contingencies" (“ASC 450”) governs the Company’s disclosure and recognition of loss contingencies, including pending claims, lawsuits, disputes with third parties, investigations and other actions that are incurred in the operation of our business. ASC 450 uses the following defined terms to describe the likelihood of a future loss: probable – the future event or events are likely to occur, remote – the chance of the future event or events is slight, and reasonably possible – the chance of the future event or events occurring is more than remote but less than likely. ASC 450 also contains certain requirements with respect to how we accrue for and disclose information concerning our loss contingencies. We accrue for a loss contingency when we conclude that the likelihood of a loss is probable and the amount of the loss can be reasonably estimated. When the reasonable estimate of the loss is within a range of amounts, and no amount in the range constitutes a better estimate than any other amount, we accrue for the amount at the low end of the range. We adjust our accruals from time to time as we receive additional information, but the loss we incur may be significantly greater than or less than the amount we have accrued. We disclose loss contingencies if there is at least a reasonable possibility that a material loss has been incurred. No accrual or disclosure is required for losses that are remote. Arlisa Ann Carr, Individually and as Representative of the Estate of Dexture Carr, Deceased v. Dewan Tyrel Mosley and C&J Well Services, Inc.: On or around October 2, 2018, Arlisa Carr filed a lawsuit against CJWS in the 115th District Court of Upshur County, Texas (Cause No.630-18), alleging, among other things, that CJWS was negligent with respect to an automobile accident in March 2018. MS. Carr is seeking monetary relief of more than $1 million. CJWS denies these allegations and the case is currently set for trial in April 2021. The outcome of this case is uncertain and the ultimate resolution of it could have a material adverse effect on our consolidated financial statements in the period in which the resolution is recorded. We believe that costs associated with other legal matters, individually or in the aggregate, will not have a material adverse effect on our consolidated financial statements. Sales and Use Tax Audit The Company is subject to sales and use tax audits as a normal course of its business. The Company is currently subject to sales and use tax audits conducted by the Texas State Comptroller’s office for audit periods from 2010 through 2016. Preliminary audit reports were issued for these audits, and the Company will appeal the preliminary reports through the redetermination process. Based on the Company's analysis, the potential liability associated with these audits, including costs to be incurred in defending and settling these audits, range from $6.0 million up to $31.0 million. This range could potentially change in future periods as the appeal and redetermination process progresses. Net of $2.7 million of good faith payments made by the Company, the Company currently has recorded a $3.4 million liability which is included as accrued expenses on our consolidated balance sheets. Included in the $3.4 million liability is approximately $2.1 million of accrued interest associated with the tax liability, including $0.2 million of interest expense recognized for the year ended December 31, 2020. Self-Insured Risk Accruals The Company is self-insured up to retention limits as it relates to workers’ compensation, automobile liability, general liability claims, and medical and dental coverage of its employees. The Company has deductibles per occurrence for workers’ compensation, automobile liability, general liability, and medical and dental coverage of $2.0 million, $1.0 million, $1.0 million and $0.4 million, respectively. The Company maintains accruals in the accompanying consolidated balance sheets related to self-insurance retentions based upon our claims history.
