Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes We account for income taxes under the asset and liability method. We consider the operating earnings of our foreign subsidiaries to be indefinitely invested outside the United States. Therefore no provision has been made for the federal, state, or foreign taxes that may result from future remittances of undistributed earnings of our foreign subsidiaries. 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 income taxes, excluding the effects of significant unusual or infrequently occurring discrete items and the change in contingent consideration liability which is not reliably estimable. The tax effects of discrete items and the change in contingent consideration liability are recorded in the same period that the related item is reported and resulted in the difference between the actual effective tax rate for the three months ended March 31, 2015 and 2014, and the estimated annual effective tax rates for those same periods of 41.2% and 29.3%, respectively. The provision for income taxes of $19.4 million and $4.4 million for the three months ended March 31, 2015 and 2014, respectively, represented estimated federal, state, and foreign income taxes. Our annual effective tax rate diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign withholding taxes, nondeductible amortization, and net unrecognized tax benefits associated with qualified stock options, partially offset by foreign income taxed at lower tax rates, and research and development credits. Discrete items recognized in the three months ended March 31, 2015 and 2014, included additional penalties and interest for uncertain tax positions related to prior fiscal years, and tax benefits realized from share-based compensation. The provision for income taxes of $38.0 million and $22.3 million for the nine months ended March 31, 2015 and 2014, respectively, represented estimated federal, foreign, and state income taxes. Our annual effective tax rate diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign withholding taxes, nondeductible amortization, and net unrecognized tax benefits associated with qualified stock options, partially offset by foreign income taxed at lower tax rates, and research and development credits. Discrete items recognized in the nine months ended March 31, 2015 and 2014, included additional penalties and interest for uncertain tax positions related to prior fiscal years, research and development credits, and tax benefits realized from share-based compensation. Unrecognized Tax Benefits The total liability for gross unrecognized tax benefits increased $1.7 million during the nine months ended March 31, 2015 to $11.9 million from $10.2 million at June 30, 2014 and was included in other long-term liabilities on our condensed consolidated balance sheets. If recognized, this total amount would affect the effective tax rate on income from continuing operations. Accrued interest and penalties related to unrecognized tax benefits as of March 31, 2015 was $1.1 million; this balance increased by $0.2 million from June 30, 2014. We classify interest and penalties as components of income tax expense. The Tax Increase Prevention Act, or the Act, which retroactively extended the federal research tax credit from January 1, 2014 through December 31, 2014, was enacted on December 19, 2014. As such, we recognized six months of tax benefit from the federal research tax credit related to fiscal 2014 and another six months of federal research tax credit in the second quarter of fiscal 2015. In May 2011, we were notified by the Internal Revenue Service, or the Service, that our fiscal 2003 through 2006 and fiscal 2008 through 2010 returns would be subject to examination. In March 2015, we received the Revenue Agent’s Report concluding this audit without any tax adjustment. Our case is pending review by the Joint Committee on Taxation, which we anticipate will be concluded in the fourth quarter of our fiscal 2015. On March 31, 2015 Japan’s parliament approved the legislation to reduce corporate income tax rates by 3.29 percentage points over the next two years. As a result, the current combined national and local effective tax rate of 35.6% will be reduced to 32.3% over the next two years. We are currently evaluating the impact of this change which was enacted in the fourth quarter of our fiscal 2015. Our major tax jurisdictions are the United States, California, Hong Kong SAR, and Japan. From fiscal 2003 onward, we remain subject to examination by one or more of these jurisdictions.
