(“TotalEnergies”) that created a 50/50 joint venture (the “TotalEnergies JV”) to develop anaerobic digester gas (“ADG”) RNG production facilities in the United States. Each ADG RNG production facility project under the TotalEnergies JV will be formed as a separate limited liability company (“LLC”) that is owned 50/50 by the Company and TotalEnergies, and contributions to such LLCs count toward the TotalEnergies JV Equity Obligations (as defined below). The TotalEnergies JV Agreement contemplates that the TotalEnergies JV will invest up to $400.0 million of equity in production projects, and TotalEnergies and the Company each committed to initially provide $50.0 million for the TotalEnergies JV (the “TotalEnergies JV Equity Obligations”). On October 12, 2021, TotalEnergies and the Company executed a LLC agreement (the “DR Development Agreement”) for an ADG RNG production facility project (the “DR JV”). Under the DR Development Agreement, TotalEnergies and the Company have each committed to contribute $7.0 million to the DR JV. On November 1, 2021, TotalEnergies and the Company each contributed an initial $4.8 million to the DR JV. The Company accounts for its interest in the LLCs using the equity method of accounting because the Company does not control but has the ability to exercise significant influence over the LLCs’ operations. The Company recorded a loss of $0.1 million from the TotalEnergies JV for the three and six months ended June 30, 2022. The Company had an investment balance in the TotalEnergies JV of $4.7 million and $4.6 million as of December 31, 2021 and June 30, 2022, respectively. bp Joint Venture On April 13, 2021, the Company entered an agreement (the “bp JV Agreement”) with bp Products North America Inc. (“bp”) that created a 50/50 joint venture (the “bpJV”) to develop, own and operate new ADG RNG production facilities in the United States. Pursuant to the bp JV Agreement, bp and the Company committed to provide $50.0 million and $30.0 million, respectively, with bp and the Company each receiving 30.0 million of Class A Units in the bpJV and bp also receiving 20.0 million of Class B Units in the bpJV. bp’s initial $50.0 million contribution was made on April 13, 2021 and consisted of all unpaid principal outstanding under the loan agreement dated December 18, 2020, pursuant to which bp advanced $50.0 million to the Company to fund capital costs and expenses incurred prior to formation of the bpJV, including capital costs and expenses for permitting, engineering, equipment, leases and feed stock rights. 100% of the RNG produced from the projects developed and owned by the bpJV will be provided to the vehicle fuels market pursuant to the Company’s marketing agreement with bp. Pursuant to the bp JV Agreement, the Company had the option, exercisable prior to August 31, 2021 (the “bp Option”), to commit an additional $20.0 million to the bpJV upon which bp’s Class B Units would convert into Class A Units.
