Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Unrecognized Tax Benefits In the third quarter of fiscal year 2021, we released unrecognized tax benefits upon expiration of the statute of limitations on uncertain tax positions taken in prior years. As a result, we recorded a net tax benefit of $21.5, including interest, as a component of continuing operations. This included the impact from the release of reserves associated with a 2017 tax election related to a non-U.S. subsidiary. In addition, we recorded a net tax benefit of $8.2 as a component of discontinued operations for the release of reserves related to our former EfW business. As of 30 June 2021, our unrecognized tax benefits, excluding interest and penalties, were $207.7, of which $75.4 would impact the effective tax rate from continuing operations if recognized. As of 30 September 2020, our unrecognized tax benefits, excluding interest and penalties, were $237.0. It is reasonably possible that additional reserves for uncertain tax positions associated with discontinued operations could be released in the fourth quarter of fiscal year 2021. We estimate this could result in a net tax benefit of approximately $50. India Finance Act 2020 On 27 March 2020, the Indian government passed Finance Act 2020 (the "India Finance Act"), which amended rules regarding the taxation of dividends declared and distributed by Indian companies. Under the India Finance Act, future dividends declared or distributed by an Indian company are no longer subject to dividend distribution tax. Instead, any non-resident recipient is subject to a withholding tax. Our consolidated income statements for the nine months ended 30 June 2020 included a net benefit of $13.5 as a result of the India Finance Act. The net benefit included $33.8 for our share of accumulated dividend distribution taxes released with respect to INOX Air Products Private Limited ("INOX"), an equity affiliate investment in our Industrial Gases – Asia segment. This benefit was reflected within "Equity affiliates' income" and was not recorded in segment results. In addition, our income tax provision reflected an expense of $20.3 for estimated withholding taxes that we may incur on future dividends related to INOX. Effective Tax Rate Our effective tax rate was 16.3% and 18.6% for the three and nine months ended 30 June 2021, respectively. The effective tax rate was 19.3% and 20.7% for the three and nine months ended 30 June 2020, respectively. Cash Paid for Taxes (Net of Cash Refunds) Income tax payments, net of refunds, were $284.8 and $329.6 for the nine months ended 30 June 2021 and 2020, respectively. Fiscal year 2021 reflects an income tax refund of $6.7 that is related to cash provided by discontinued operations.
