Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes The Company recorded an income tax provision of $4.8 million during the three months ended December 31, 2020. The tax provision for the three months ended December 31, 2020 was primarily driven by the provision on earnings from operations during the period which was partially offset by a $2.5 million discrete stock compensation windfall benefit for tax deductions that exceeded the associated book compensation expense. The Company recorded an income tax benefit of $3.0 million during the three months ended December 31, 2019. The tax benefit was primarily driven by a $5.8 million stock compensation windfall benefit for tax deductions that exceeded the associated compensation expense and a $0.5 million reduction in deferred tax liabilities related to the extension of a tax rate incentive in China. These discrete benefits were partially offset by the tax provision on earnings from operations during the 2019 period. During March 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act which contains numerous income tax provisions among other tax and non-tax provisions. Some of these income tax provisions have retroactive effects on years before the date of enactment. During December 2020, the United States enacted the Consolidated Appropriations Act 2021 which also contains numerous income tax provisions among other tax and non-tax provisions. The Company evaluated the legislation of both Acts in relation to income taxes and determined that the income tax Acts do not have a material impact on its income tax provision. The Company evaluates the realizability of its deferred tax assets by tax-paying component and assesses the need for a valuation allowance on a quarterly basis. The Company evaluates the profitability of each tax-paying component on a historic cumulative basis and a forward-looking basis while performing this analysis. The Company maintains a U.S. valuation allowance related to the realizability of certain state tax credits and state net operating loss carry-forwards, as well as a valuation allowance against net deferred tax assets on certain foreign tax-paying components as of December 31, 2020. The Company maintains liabilities for uncertain tax positions. These liabilities involve judgment and estimation and are monitored based on the best information available. The Company recognizes interest related to unrecognized tax benefits as a component of “Income tax provision (benefit)” in the Company’s Consolidated Statements of Operations. The Company recognized interest expense related to its uncertain tax positions of $0.3 million during the three months ended December 31, 2020. The Company is subject to U.S. federal, state, local and foreign income taxes in various jurisdictions. The amount of income taxes paid is subject to the Company’s interpretation of applicable tax laws in the jurisdictions in which it files. In the normal course of business, the Company is subject to income tax audits in various global jurisdictions in which it operates. The years subject to examination vary for the U.S. and international jurisdictions, with the earliest tax year being 2013. Based on the outcome of these examinations or the expiration of statutes of limitations for specific jurisdictions, it is reasonably possible that the related unrecognized tax benefits could change from those recorded in the Company’s Consolidated Balance Sheets. The Company currently anticipates that it is reasonably possible that the unrecognized tax benefits and accrued interest on those benefits will be reduced by an amount in the range of $2.5 million to $18.0 million in the next 12 months due to statute of limitations expirations. These unrecognized tax benefits would impact the effective tax rate if recognized.
