Equity Method Investments and Joint Ventures [Abstract]
Equity Affiliates	EQUITY AFFILIATES Equity Affiliate Investment in Jazan Integrated Gasification and Power Company (“JIGPC”) On 27 October 2021, we made an initial investment of $1.6 billion in Jazan Integrated Gasification and Power Company ("JIGPC"). JIGPC is a joint venture with Saudi Aramco Power Company (a subsidiary of Aramco), ACWA Power, and Air Products Qudra in the Jazan Economic City, Saudi Arabia. Our investment represents a 55% interest in the joint venture, of which 4% is attributable to the noncontrolling partner of Air Products Qudra. The $1.6 billion investment, which includes approximately $130 from the non-controlling partner, is primarily in the form of shareholder loans that qualify as in-substance common stock in the joint venture. We determined JIGPC is a variable interest entity for which we are not the primary beneficiary as we do not have the power to direct the activities that are most significant to the economic performance of the joint venture. Instead, these activities, including plant dispatch, operating and maintenance decisions, budgeting, capital expenditures, and financing, require unanimous approval of the owners or are controlled by the customer. Since we have the ability to exercise significant influence in the joint venture, we accounted for our investment in JIGPC under the equity method within the Middle East and India segment. Certain shareholders receive a preferred cash distribution pursuant to the joint venture agreement, which specifies each shareholder’s share of income after considering the amount of cash available for distribution. As such, the earnings attributable to Air Products may not be proportionate to our ownership interest in the venture. As of 31 December 2022, the carrying value of our investment totaled $1,776.5 and is presented as “Investments in net assets of and advances to equity affiliates” on our consolidated balance sheet. Our loss exposure is limited to our investment in the joint venture. Subsequent Event On 19 January 2023, we made an additional investment of $908 toward the second phase of the project as further discussed below. This investment included $73 received from the noncontrolling partner of Air Products Qudra. We expect to complete a remaining investment of approximately $115, including approximately $9 from the non-controlling partner of Air Products Qudra, later this calendar year. JIGPC Joint Venture On 27 September 2021, JIGPC signed definitive agreements for the acquisition of project assets from Aramco for $12 billion and entered into related project financing for the purchase of the project assets, which include power blocks, gasifiers, air separation units, syngas cleanup assets, and utilities, in two phases. The first phase was completed on 27 October 2021 for $7 billion, and the second phase was completed for $4.15 billion on 19 January 2023. We expect final commissioning items to be completed later this calendar year. JIGPC will commission, operate, and maintain the project assets to supply electricity, steam, hydrogen, and utilities to Aramco’s refinery and terminal complex under a 25-year agreement, which commenced in the first quarter of fiscal year 2022. JIGPC recorded financing receivables upon acquisition of the assets and is recognizing financing income over the supply term. Jazan Gas Project Company Jazan Gas Project Company (“JGPC”), a joint venture between Air Products and ACWA Holding, entered into a 20-year oxygen and nitrogen supply agreement in 2015 to supply Aramco’s oil refinery and power plant in Jazan, Saudi Arabia. In October 2021, the supply agreement between JGPC and Aramco was terminated, and JGPC sold its air separation units to Aramco. We initially sold these assets to JGPC and deferred profit proportionate to our ownership in the joint venture. With the termination of the supply agreement and sale of the air separation units complete, we recognized the remaining deferred profit, net of other project finalization costs, in equity affiliates’ income in the first quarter of fiscal year 2022.
