Acquisitions [Abstract]
Acquisitions	ACQUISITIONS Fiscal Year 2020 Asset Acquisition On 17 April 2020, we acquired five operating hydrogen production plants from PBF Energy Inc. ("PBF") and commenced contractual long-term supply of hydrogen from those plants to PBF's refineries. We accounted for the transaction as an asset acquisition and recorded the aggregate purchase price of approximately $580 to plant and equipment on our consolidated balance sheets. Business Combinations We completed three acquisitions on 1 July 2020 that were accounted for as business combinations. These acquisitions had an aggregate purchase price, net of cash acquired, of $185.4. The largest of these acquisitions was the purchase of Oxygen & Argon Works Ltd., the leading manufacturer and marketer of industrial gases in Israel, primarily offering merchant gas products. We expect this acquisition to create growth opportunities in the region and allow us to leverage synergies and operating efficiencies. The results of this business are consolidated within our Industrial Gases – EMEA segment and did not materially impact our consolidated income statement. Our fiscal year 2020 business combinations resulted in the recognition of plant and equipment of $71.2, goodwill of $71.1, and intangible assets of $50.7, partially offset by net liabilities acquired. The goodwill recognized on the transactions, $8.1 of which is deductible for tax purposes, is attributable to expected growth and cost synergies. The intangible assets recognized primarily resulted from acquired customer relationships, having a weighted-average useful life of 19 years. The acquired assets and liabilities resulting from our 2020 business combinations were recorded at their estimated fair values, which were calculated based primarily on a preliminary purchase price allocation prepared by independent valuation specialists. We may record adjustments to these assets and liabilities during the preliminary purchase price allocation period, which could be up to one year from the acquisition date. Fiscal Year 2019 As further discussed below, we completed three business combinations in fiscal year 2019. Exchange of Equity Affiliate Investments We previously held 50% ownership interests in High-Tech Gases (Beijing) Co., Ltd. ("High-Tech Gases") and WuXi Hi-Tech Gas Co., Ltd. ("WuXi"), both of which were joint ventures with another industrial gas company in China. We accounted for these arrangements as equity method investments in our Industrial Gases – Asia segment through 30 April 2019. On 1 May 2019, we acquired our partner's 50% interest in WuXi in exchange for our 50% interest in High-Tech Gases. The exchange resulted in a net gain of $29.1, of which $15.0 resulted from the revaluation of our previously held equity interest in WuXi to its acquisition date fair value and $14.1 resulted from the disposition of our interest in High-Tech Gases. The net gain was reflected as "Gain on exchange of equity affiliate investments" on our consolidated income statements in fiscal year 2019 and was excluded from the results of the Industrial Gases – Asia segment. We revalued our previously held 50% equity interest in WuXi based on an estimated acquisition date fair value of $27.0. We calculated this fair value using a discounted cash flow analysis under the income approach, which required estimates and assumptions regarding projected revenue growth, customer attrition rates, profit margin, and discount rate. The acquisition of the remaining interest in WuXi was accounted for as a business combination. The results of this business are consolidated within our Industrial Gases – Asia segment. Other Fiscal Year 2019 Business Combinations The remaining business combinations completed in fiscal year 2019 had total consideration, net of cash acquired, of $126.6. The largest of these business combinations was the acquisition of ACP Europe SA ("ACP"), the largest independent carbon dioxide business in Continental Europe, which closed in the second quarter. The results of this business are consolidated within our Industrial Gases – EMEA segment. Fiscal Year 2018 Asset Acquisition On 26 April 2018 ("the acquisition date"), we completed the formation of Air Products Lu An (Changzhi) Co., Ltd. (the “JV”), a 60%-owned joint venture with Lu’An Clean Energy Company ("Lu’An"). The results of the JV are consolidated within the Industrial Gases – Asia segment. Air Products contributed four large air separation units to the JV, and the JV acquired gasification and syngas clean-up assets from Lu’An. We accounted for the acquisition of the gasification and syngas clean-up assets as an asset acquisition. In connection with closing the acquisition, we paid net cash of approximately 1.5 billion RMB ($235) and issued equity of 1.4 billion RMB ($227) to Lu'An for their noncontrolling interest in the JV. In addition, Lu'An made a loan of 2.6 billion RMB to the JV, and we established a liability for remaining cash payments. The issuance of equity to Lu'An for their noncontrolling interest, the long-term debt, and the liability for the remaining cash payments were noncash transactions that were excluded from the consolidated statement of cash flows for the fiscal year ended 30 September 2018. Refer to Note 15, Debt, for additional information on our related party debt. Business Combinations We completed eight acquisitions that were accounted for as business combinations in fiscal year 2018. These acquisitions had total consideration, net of cash acquired, of $355.4. The largest of the acquisitions was completed during the first quarter of fiscal year 2018 and primarily consisted of three air separation units serving onsite and merchant customers in China. The results of this business are consolidated within our Industrial Gases – Asia segment.
