Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Our financial instruments consist of cash and cash equivalents, receivables, payables and debt instruments. We believe that the carrying values of these instruments on the accompanying consolidated balance sheets approximate their fair values. As of December 31, 2022 and 2021, we believe the carrying value of our floating-rate debt outstanding under our term loans and revolving credit facilities approximates fair value because the terms include short-term interest rates and exclude penalties for prepayment. We estimated the fair value of our floating-rate term loan and revolving credit facilities using significant other observable inputs, representative of a Level 2 fair value measurement, including terms and credit spreads for these loans. In addition, the estimated fair value of our assets held for sale is based upon Level 2 fair value measurements, which include appraisals and previous negotiations with third parties. During the first quarter of 2020, we recorded a goodwill impairment charge related to one of our reporting units. Our estimates of fair value required us to use significant unobservable inputs, representative of Level 3 fair value measurements, including numerous assumptions with respect to future circumstances that might directly impact each of the relevant asset groups’ operations in the future and are therefore uncertain. These assumptions with respect to future circumstances included future cash flows, oil, met coal and natural gas prices, anticipated spending by our customers, the cost of capital, and industry and/or local market conditions. We estimated the fair value when conducting the first quarter of 2020 goodwill impairment test primarily using an income approach. The discount rates used to value our reporting units for the first quarter of 2020 for the goodwill impairment test ranged between 10.5% and 14.0%. During the fourth quarter of 2022, the second quarter of 2021 and the first quarter of 2020, we wrote down certain long-lived assets to fair value. During the first quarter of 2020, we estimated the fair value when conducting the long-lived asset impairment tests primarily using an income approach. We used a variety of unobservable inputs and underlying assumptions consistent with those discussed above for purposes of our goodwill impairment test. The discount rates used to value our Canadian and U.S. segments long-lived asset impairment analysis ranged between 11.0% and 14.0%. Additionally, during the first quarter of 2020 and the fourth quarter of 2022, our estimate of fair value of a property in the U.S. was based on appraisals from third parties, which referenced available market information, such as listing agreements, offers, and pending and closed sales. During the second quarter of 2021 and the fourth quarter of 2022, our estimate of fair value in Australia for assets that were impaired, was based on appraisals from third parties. See Note 2 – Summary of Significant Accounting Policies – Impairment of Long-Lived Assets and Note 2 – Summary of Significant Accounting Policies – Goodwill and Other Intangible Assets for further discussion of the significant judgments and assumptions used in calculating their fair value.
