Business Segments In accordance with Accounting Standard Codification (ASC) No. 280, Segment Reporting (ASC 280), the Company routinely evaluates whether its separate segments have changed. This determination is made based on the following factors: (1) the Companys chief operating decision maker (CODM) is currently managing each operating segment as a separate business and evaluating the performance of each segment and making resource allocation decisions distinctly and expects to do so for the foreseeable future, and (2) discrete financial information for each operating segment is available. In 2019, due to the transformative nature of the C&amp;J Merger, the CODM changed the way in which the Company is managed, including the level at which to make performance evaluation and resource allocation decisions. Discrete financial information was created to provide the segment information necessary for the CODM to manage the Company under the revised operating segment structure. On March 9, 2020, the Company announced it had completed the divestiture of its Well Support Services segment. As a result of the changes to operating segments, the Company revised its reportable segments subsequent to the completion of the C&amp;J Merger and Well Support Services segment divestiture. For the period from after the C&amp;J merger and prior to the WSS divestiture, the Companys revised reportable segments were: (i) Completion Services, (ii) Well Construction and Intervention (WC&amp;I) and (iii) Well Support Services. Subsequent to the WSS divestiture, the Company's reportable segments were (i) Completion Services, and (ii) Well Construction and Intervention (WC&amp;I) Services. This segment structure reflects the financial information and reports used by the Companys management, specifically including its CODM, to make decisions regarding the Companys business, including performance evaluation and resource allocation decisions. As a result of the revised reportable segment structure subsequent to the C&amp;J merger, the Company has restated the corresponding items of segment information for all periods presented. The following is a description of each reportable segment: Completion Services The Companys Completion Services segment consists of the following businesses and service lines: (1) fracturing services; (2) wireline and pumpdown services; and (3) completion support services, which includes the Company's research and technology department. Well Construction and Intervention Services The Companys WC&amp;I Services segment consists of the following businesses and service lines: (1) cementing services and (2) coiled tubing services. Well Support Services The Companys Well Support Services segment consisted of the following businesses and service lines: (1) rig services; (2) fluids management services; and (3) other specialty well site services. On March 9, 2020, the Company completed the divestiture of its Well Support Services segment for $93.7 million of total proceeds, including $59.4 million in cash, before transaction costs, escrowed amounts, and subject to customary working capital adjustments, for a net of $53.3 million received at close, and $34.4 million of par value Senior Secured Notes, with 10.75% coupon rate, ("WSS Notes") previously issued by Basic. This resulted in a preliminary gain on divestiture of $8.0 million , subject to change upon finalization of a potential net working capital adjustment. The gain is recorded within (Gain) Loss on Disposal of Assets on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). Income per share for the three months ended March 31, 2020 attributable to the divested Well Support Services segment was less than zero . The following tables present financial information with respect to the Companys segments.
