Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments	Refining and Logistics Equity Investments Yellowstone Energy Limited Partnership On June 1, 2023, we completed the Billings Acquisition (as defined in Note 5—Acquisitions) and acquired a 65% limited partnership ownership interest in YELP. YELP owns a cogeneration facility in Billings, Montana, that converts petroleum coke, supplied from our Montana refinery and other nearby third-party refineries, into power production for the local utility grid. As of June 30, 2023, our investment in YELP was $58.0 million. We account for our investment in YELP using the equity method as we have the ability to exert significant influence over, but do not control its operating and financial policies. Our proportionate share of YELP’s net income (loss) will be recorded on a one-month lag basis and included in Equity (earnings) from refining and logistics investments on our condensed consolidated statements of operations. Yellowstone Pipeline Company On June 1, 2023, we completed the Billings Acquisition (as defined in Note 5—Acquisitions) and acquired a 40% ownership interest in YPLC. YPLC owns a refined products pipeline that begins at our Montana refinery and transports refined product to Montana and the Pacific Northwest. As of June 30, 2023, our investment in YPLC was $26.4 million. We account for our ownership interest in YPLC using the equity method as we have the ability to exert significant influence over, but do not control its operating and financial policies. Our proportionate share of YPLC’s net income of $0.4 million for the three and six months ended June 30, 2023 is included in Equity (earnings) from refining and logistics investments on our condensed consolidated statements of operations. Additionally, on June 28, 2023, YPLC made a cash dividend to its shareholders, of which our proportionate share was $2.6 million. Investment in Laramie Energy Laramie Energy As of June 30, 2023, we had a 46.0% ownership interest in Laramie Energy. Laramie Energy is focused on developing and producing natural gas in Garfield, Mesa, and Rio Blanco counties, Colorado. The balance of our investment in Laramie Energy was zero as of June 30, 2023 and December 31, 2022. Prior to February 21, 2023, Laramie Energy had a term loan agreement which provided a term loan secured by a lien on its natural gas and crude oil properties and related assets. Under the terms of the term loan, Laramie Energy was generally prohibited from making future cash distributions to its owners, including us, except for certain permitted tax distributions. On February 21, 2023, Laramie Energy entered into a new term loan agreement which provides a $205 million first lien term loan facility with $160.0 million funded at closing and an optional $45 million delayed draw commitment, subject to certain terms and conditions. Laramie Energy used the proceeds from the term loan to repay the then-outstanding balance of $76.3 million on its prior term loan, including accrued interest and prepayment penalties, and fully redeem preferred equity of $73.5 million. After deducting transaction costs, net proceeds were $4.8 million. Under the terms of the new term loan, Laramie is permitted to make future cash distributions to its owners, including us, subject to certain restrictions. Laramie Energy’s term loan matures on February 21, 2027. As of June 30, 2023, the term loan had an outstanding balance of $155.0 million. On March 1, 2023, pursuant to its new term loan agreement, Laramie Energy made a one-time cash distribution to its owners, including us, based on ownership percentage. Our share of this distribution was $10.7 million, which was reflected as Return of capital from Laramie Energy, LLC on our condensed consolidated statements of cash flows. We recorded the cash received as Equity earnings from Laramie Energy, LLC on our condensed consolidated statements of operations because the carrying value of our investment in Laramie Energy was zero at the time of such distribution. Effective February 21, 2023, and concurrent with the new term loan agreement noted above, we resumed the application of equity method accounting with respect to our investment in Laramie Energy. At June 30, 2023, our equity in the underlying net assets of Laramie Energy exceeded the carrying value of our investment by approximately $76.4 million. This difference arose primarily due to other-than-temporary impairments of our equity investment in Laramie Energy.
