Income Taxes	9 Months Ended
Income Taxes	Mar. 31, 2020
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The effective income tax rates for the three months ended March 31, 2021 and 2020 were 8.0 percent (benefit on income) and 93.1 percent (provision on income), respectively. The year-over-year change is primarily due to the effects of changes in projected pretax income in both periods and two discrete tax benefits that were recorded in the current year quarter. The first discrete tax benefit of $12.4 million is a provision to return adjustment related to our fiscal 2020 U.S. income tax returns, the majority of which is attributable to a tax election made in our federal income tax return pursuant to global intangible low-taxed income (GILTI) regulations which were issued during the current fiscal year. The second discrete tax benefit of $3.5 million is the recognition of a stranded deferred tax balance in accumulated other comprehensive loss arising from valuation allowance adjustments and enacted tax rate changes associated with the forward starting interest rate cash flow hedges that were terminated during the current year quarter (see Note 10). The prior year rate included the effects from the impairment of goodwill and other intangible asset impairment charges in the former Widia segment. The effective income tax rates for the nine months ended March 31, 2021 and 2020 were 84.6 percent (benefit on income) and 143.5 percent (benefit on a loss), respectively. The year-over-year change is primarily due to (i) the effects of relatively low projected pretax income in the current year quarter coupled with a relatively low projected pretax loss in the prior year quarter, and (ii) two discrete tax benefits that were recorded in the current year quarter. The first discrete tax benefit of $12.4 million is a provision to return adjustment related to our fiscal 2020 U.S. income tax returns, the majority of which is attributable to a tax election made in our federal income tax return pursuant to global intangible low-taxed income (GILTI) regulations which were issued during the current fiscal year. The second discrete tax benefit of $3.5 million is the recognition of a stranded deferred tax balance in accumulated other comprehensive loss arising from valuation allowance adjustments and enacted tax rate changes associated with the forward starting interest rate cash flow hedges that were terminated during the current year quarter (see Note 10). The prior year rate included a discrete $14.5 million benefit for the one-time effect of Swiss tax reform and the effects from the impairment of goodwill and other intangible asset impairment charges in the former Widia segment. Swiss tax reform Legislation was effectively enacted during the three months ended December 31, 2019 when the Canton of Schaffhausen approved the Federal Act on Tax Reform and AHV Financing on October 8, 2019 (Swiss tax reform). Significant changes from Swiss tax reform include the abolishment of certain favorable tax regimes and the creation of a ten-year transitional period at both the federal and cantonal levels. The transitional provisions of Swiss tax reform allow companies to utilize a combination of lower tax rates and tax basis adjustments to fair value, which are used for tax depreciation and amortization purposes resulting in deductions over the transitional period. To reflect the federal and cantonal transitional provisions, as they apply to us, we recorded a deferred tax asset of $14.5 million during the three months ended December 31, 2019. We consider the deferred tax asset from Swiss tax reform to be an estimate based on our current interpretation of the legislation, which is subject to change based on further legislative guidance, review with the Swiss federal and cantonal authorities and modifications to the underlying valuation. We expect such reviews with the relevant tax authorities will be finalized during the fourth quarter of the current fiscal year or the first quarter of fiscal 2022. There have been no material changes to the recorded deferred tax asset since inception.
