Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | The following table sets forth specified executive compensation and financial performance measures for the Company’s three most recently completed fiscal years, and cumulative total shareholder return (TSR) information for the Company and a peer group for the 1-, 2- and 3-year periods commencing as of December 31, 2019, as required by Item 402(v) of Regulation S-K:

(1) The dollar amounts reported in this column represent the amount of “compensation actually paid” to our Principal Executive Officer ("PEO"), as computed in accordance with Item 402(v) of Regulation S-K and do not reflect the total compensation actually realized or received. In accordance with these rules, these amounts reflect Total compensation as set forth in the Summary Compensation Table for each year, adjusted as shown below. The fair value of performance unit and phantom unit awards was determined based on a Monte-Carlo simulation model that takes into account expected price movement of Patterson-UTI stock as compared to peer companies and relevant market indices, as of the relevant measurement dates. Assumptions used in the Monte-Carlo simulation model include assumptions regarding volatility, the risk-free interest rate, dividend yield, and stock beta. Due to differences in measurement dates, the assumptions used in these valuations could differ materially from the assumptions used to determine the fair value as of the grant date of such awards.

(2) The non-PEO Named Executive Officers for each of the covered fiscal years are Messrs. Smith, Berns, Holcomb and Wexler. (3) The dollar amounts reported in this column represent the average amount of “compensation actually paid” to the other Named Executive Officers, as computed in accordance with Item 402(v) of Regulation S-K and do not reflect the total compensation actually realized or received by the Named Executive Officers. In accordance with these rules, these amounts reflect average Total compensation as set forth in the Summary Compensation Table for each year, adjusted as shown below. The fair value of performance unit awards was determined based on a Monte-Carlo simulation model that takes into account expected price movement of Patterson-UTI stock as compared to peer companies and relevant market indices, as of the relevant measurement dates. Assumptions used in the Monte-Carlo simulation model include assumptions regarding volatility, the risk-free interest rate, dividend yield, and stock beta.

(4) The peer group used for the calculation of Peer Group Total Shareholder Return is the Oilfield Service Index(OSX). (5) The Company-Selected Measure is Operating Cash Flow, which is not defined by U.S. GAAP. Operating cash flow is defined herein as Adjusted EBITDA less cash capital expenditures (as adjusted for any Board-approved increase in capital expenditures after targets were set). Adjusted EBITDA is defined herein as net income (loss) plus net interest expense, income tax expense (benefit) and depreciation, depletion, amortization and impairment expense (including impairment of goodwill), excluding any M&A related or restructuring charges (and, for 2020, excluding the impact of a $9.2 million charge to reduce the carrying value of a deposit for future sand purchases). (6) While SEC guidance under Item 402(v) of Regulation S-K does not permit the use of multi-year relative Total Shareholder Return as a permissible Company-Selected Measure for the table above, the Company views 3-year relative Total Shareholder Return as the most important measure used to link executive “compensation actually paid” to Company performance. |  |
