Also in conjunction with the Corporate Reorganization, Liberty Holdings contributed $2.1 million of assets to Liberty LLC and Redeemable Common Units in the amount of $42.6 million were settled. In September 2011, Liberty Resources LLC, an oil and gas exploration and production company, and its successor entity (collectively, the “Affiliate”) and LOS, companies with common ownership and management, entered into a services agreement (the “Services Agreement”) whereby the Affiliate was to provide certain administrative support functions to LOS and a master service agreement whereby LOS provides hydraulic fracturing services to the Affiliate at market service rates. The amounts incurred under the Services Agreement by LOS during the three months ended March 31, 2018, were $0.2 million, and there was no payable outstanding as of March 31, 2019 and December 31, 2018 as the Services Agreement was terminated during June 2018. The amounts of the Company’s revenue related to hydraulic fracturing services provided to the Affiliate for the three months ended March 31, 2019 and 2018 was $6.3 million and $3.9 million, respectively. As of March 31, 2019 and December 31, 2018, $10.8 million and $15.1 million, respectively, of the Company’s accounts receivable was with the Affiliate. The Company had no unbilled revenue with the Affiliate as of March 31, 2019 and December 31, 2018.

The advisory services agreement was terminated pursuant to an agreement effective as of January 11, 2018.

As part of this crystallization, R/C and affiliated entities (collectively, the “R/C Affiliates”) received shares of Class A Common Stock, including 117,647 shares of Class A Common Stock (such 117,647 shares referred to as the “Issued Shares”) to compensate R/C Affiliates for certain accrued preferred returns but which would not have been issued had the $2.0 million in fees owed under the advisory agreement been paid in cash. Had this fee been paid in cash on or prior to January 11, 2018, R/C and Liberty Holdings acknowledge that R/C Affiliates would not have received the Issued Shares in the crystallization pursuant to the provisions of the Holdings LLC Agreement. Subsequently, during the fourth quarter of 2018, R/C asserted that certain provisions of the termination of services agreement provided for R/C to receive $2.0 million in cash as payment of those accrued fees. To resolve this matter, the Company agreed to pay R/C Affiliates $2.0 million in cash in exchange for the purchase, at the IPO price, or return of the Issued Shares and $0.3 million for interest and the settlement of the matter. Accordingly, $2.3 million was recorded as accrued liabilities - related party in the accompanying condensed consolidated balance sheet as of December 31, 2018 and subsequently paid in January 2019. The purchased and returned shares of Class A Common Stock were canceled and retired, and the Company does not expect to incur future expense related to the advisory agreement or termination thereof. During 2016, Liberty Holdings entered into a future commitment to invest and become a noncontrolling minority member in Proppant Express Investments, LLC, the owner of Proppant Express Solutions, LLC (“PropX”), a provider of proppant logistics equipment. LOS was party to a services agreement (the “PropX Services Agreement”) whereby LOS was to provide certain administrative support functions to PropX, and LOS is to purchase and lease proppant logistics equipment from PropX. The PropX Services Agreement was terminated on May 29, 2018, however the Company continues to purchase and lease equipment from PropX. For the three months ended March 31, 2019 and 2018, the Company purchased proppant logistics equipment of $0 and $2.1 million, and leased proppant logistics equipment for $2.4 million and $1.6 million, respectively. During the three months ended March 31, 2018, in exchange for a 5% discount, the Company made a prepayment to PropX for rented equipment in the amount of $5.4 million, all of which was recognized in the year ended December 31, 2018.
