Equity Method Investments and Joint Ventures [Abstract] |
Equity Method Investment | We have a 50% ownership interest in Point Lisas Nitrogen Limited (PLNL), which operates an ammonia production facility in Trinidad and Tobago. We include our share of the net earnings from this equity method investment as an element of earnings from operations because PLNL provides additional production to our operations and is integrated with our other supply chain and sales activities in the Ammonia segment. PLNL operates an ammonia plant that relies on natural gas supplied, under a gas sales contract (the Prior NGC Contract), by The National Gas Company of Trinidad and Tobago Limited (NGC). The Prior NGC Contract was scheduled to expire on January 1, 2026. NGC and PLNL had entered into short-term extension letter agreements that provided for the continued supply of gas while the parties sought to negotiate terms and conditions for a new gas sales contract for 2026. In March 2026, NGC and PLNL entered into a new gas sales contract that expires on January 1, 2027. Any NGC commitment to supply gas beyond 2026 would require further negotiations between NGC and PLNL. If NGC does not make sufficient quantities of natural gas available to PLNL at prices and terms that permit profitable operations, PLNL may cease operating its facility, which would trigger an impairment assessment of our remaining investment in PLNL. As of March 31, 2026, the total carrying value of our equity method investment in PLNL was $39 million. We have transactions in the normal course of business with PLNL reflecting our obligation to purchase 50% of the ammonia produced by PLNL at current market prices. Our ammonia purchases from PLNL totaled $38 million and $34 million for the three months ended March 31, 2026 and 2025, respectively.
