Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes We account for income taxes under the asset and liability method. The provision for income taxes recorded in interim periods is recorded by applying the estimated annual effective tax rate to year-to-date income before provision for income taxes, excluding the effects of significant unusual or infrequently occurring discrete items. The tax effects of discrete items are recorded in the same period that the related discrete items are reported and results in a difference between the actual effective tax rate and the estimated annual effective tax rate. The benefit for income taxes of $4.9 million and $0.3 million for the three months ended September 30, 2019 and 2018, respectively, represented estimated federal, foreign, and state income taxes. The effective tax rate for the three months ended September 30, 2019 diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign deemed-paid taxes, foreign income taxed at higher tax rates, and global intangible low-taxed income, or GILTI, partially offset by the benefit of research credits and foreign tax credits. The effective tax rate for the three months ended September 30, 2018, diverged from the combined U.S. federal and state statutory tax rate, primarily because of the benefit of research credits, foreign tax credits, foreign-derived intangible income deduction, excess share-based compensation deductions, release of reserves related to uncertain tax positions and foreign income taxed at lower tax rates, partially offset by foreign withholding taxes, nondeductible amortization, the impact of accounting for qualified stock options, and GILTI. The total liability for gross unrecognized tax benefits related to uncertain tax positions increased $1.2 million during the three months ended September 30, 2019, to $20.1 million from $18.9 million at June 30, 2019, and was included in other long-term liabilities on our condensed consolidated balance sheets. If recognized, the total gross unrecognized tax benefits would reduce the effective tax rate on income from continuing operations. Accrued interest and penalties related to unrecognized tax benefits as of September 30, 2019 were $1.7 million; this balance decreased by $0.2 million compared to June 30, 2019. We classify interest and penalties as components of income tax expense. It is reasonably possible that the amount of the liability for unrecognized tax benefits may change within the next twelve months and an estimate of the range of possible changes includes an increase in our liability of up to $2.5 million. In June 2019, the U.S. Ninth Circuit Court of Appeals reversed the 2015 decision of the U.S. Tax Court in Altera Corp. v. Commissioner which found that the Treasury regulations addressing the treatment of stock-based compensation in a cost-sharing arrangement with a related party were invalid. As our tax filing position is consistent with the Treasury regulations, no adjustment to our financial statements is required. However, due to the uncertainties with respect to the ultimate resolution, we will continue to monitor developments in this case. Our major tax jurisdictions are the United States, Hong Kong SAR, and Japan. From fiscal 2013 onward, we remain subject to examination by one or more of these jurisdictions. In August 2018, we received the revenue agent’s report resolving the fiscal 2014 and fiscal 2015 examination by the Internal Revenue Service with no material impact on our condensed consolidated financial statements. Our case was reviewed by the Joint Committee on Taxation, which concluded in September 2019 with no further impact to our condensed consolidated financial statements.
