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 December 31, 2014 and 2013, and the estimated annual effective tax rates for those same periods of 39.0% and 27.2%, respectively. The provision for income taxes of $7.8 million and $5.2 million for the three months ended December 31, 2014 and 2013, 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 income taxed at lower tax rates, and research and development credits, partially offset by foreign withholding taxes, nondeductible amortization, and net unrecognized tax benefits associated with qualified stock options. Discrete items recognized in the three months ended December 31, 2014 and 2013, 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. The provision for income taxes of $18.1 million and $17.9 million for the six months ended December 31, 2014 and 2013, 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 income taxed at lower tax rates, and research and development credits, partially offset by foreign withholding taxes, nondeductible amortization, and net unrecognized tax benefits associated with qualified stock options.

Unrecognized Tax Benefits The total liability for gross unrecognized tax benefits increased $1.4 million during the six months ended December 31, 2014 to $11.6 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 December 31, 2014 was $1.1 million; this balance increased by $116,000 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 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 related to 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 2013, we received the Revenue Agent’s Report resolving our examination with the Service and paid an assessment that had no material impact on our condensed consolidated financial statements. Our case is pending review by the Joint Committee on Taxation, which we anticipate will conclude in our fiscal 2015. Any prospective adjustments to our unrecognized tax benefits will be recorded as an increase or decrease to income tax expense and cause a corresponding change to our effective tax rate. Accordingly, our effective tax rate could fluctuate materially from period to period. Our major tax jurisdictions are the United States, California, Hong Kong SAR, and Japan. For fiscal 2003 onward, we remain subject to examination by one or more of these jurisdictions.
