Income Tax Disclosure [Abstract]
Income Taxes	12. 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. Accordingly, 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/(benefit) for income taxes of $4.4 million and ($12.6) million for the three months ended March 31, 2014 and 2013, respectively, represented estimated federal, foreign, and state income taxes. The provision/(benefit) for income taxes recorded in interim periods is recorded by applying the estimated annual effective tax rate to year-to-date income/(loss) before income taxes, excluding the effects of significant unusual or infrequently occurring discrete items and the change in contingent consideration liability related to the Validity acquisition which is not yet reliably estimable. The tax effects of discrete items and the change in the Validity 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, 2014 and March 31, 2013, and the estimated annual effective tax rates for those periods of 29.3% and 25.2%, respectively. The Company’s annual effective tax rate diverged from the combined U.S. federal and state statutory rate primarily because of foreign income taxed at lower tax rates and the federal research credit, partially offset by foreign withholding taxes, nondeductible amortization, contingent consideration, and net unrecognized tax benefits associated with qualified stock options. Discrete items recognized in the three months ended March 31, 2014 included additional research and development credits net of an increase in unrecognized tax benefits related to uncertain tax positions related to prior fiscal years and tax benefits realized from stock-based compensation. Discrete items recognized in the three months ended March 31, 2013 included additional research and development credits resulting from the retroactive restatement of the federal research and development credit, a decrease in unrecognized tax benefits related to uncertain tax positions, which included the remeasurement of a prior year tax position, and tax benefits realized from stock-based compensation. The provision/(benefit) for income taxes of $22.3 million and ($6.1) million for the nine months ended March 31, 2014 and 2013, respectively, represented estimated federal, foreign, and state income taxes. The provision/(benefit) for income taxes recorded in interim periods is recorded by applying the estimated annual effective tax rate to year-to-date income/(loss) before income taxes, excluding the effects of significant unusual or infrequently occurring discrete items and the change in contingent consideration liability related to the Validity acquisition which is not yet reliably estimable. The tax effects of discrete items and the change in the Validity 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 nine months ended March 31, 2014 and March 31, 2013, and the estimated annual effective tax rates for those periods of 29.3% and 25.2%, respectively.

Unrecognized Tax Benefits The total liability for gross unrecognized tax benefits increased $2.2 million during the nine months ended March 31, 2014 to $10.4 million from $8.2 million at June 30, 2013 and was included in other liabilities on our condensed consolidated balance sheets. If recognized, this total amount would affect the effective tax rate on income from continuing operations. The balance of interest and penalties accrued related to unrecognized tax benefits as of March 31, 2014 was $1.0 million and increased by $101,000 from June 30, 2013. We classify interest and penalties as components of income tax expense. 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 would be subject to examination. The early periods were being audited in connection with a mandatory review of tax refunds in excess of $2.0 million which resulted when we carried back our fiscal 2008 net operating loss. 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. On January 2, 2013, President Barack Obama signed into law The American Taxpayer Relief Act of 2013, or the Act. The Act extended the Federal research credit for two years retroactively from January 1, 2012 through December 31, 2013. As such, we will only recognize six months of tax benefit from the research tax credit in our current fiscal year. Our major tax jurisdictions are the United States, California, and Hong Kong SAR, and fiscal 2003 onward remain subject to examination by one or more of these jurisdictions.
