Income Tax Disclosure [Abstract]
Income Taxes	10. 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 for income taxes of $12.7 million and $2.5 million for the three months ended September 30, 2013 and 2012, respectively, represented estimated federal, foreign, and state income taxes. The effective tax rate for the three months ended September 30, 2013 was 26.6% and diverged from the combined 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, and net unrecognized tax benefits associated with qualified stock options. The effective tax rate for the three months ended September 30, 2012 was 29.2% and diverged from the combined federal and state statutory rate primarily because of foreign income taxed at lower tax rates, partially offset by foreign withholding taxes, net unrecognized tax benefit associated with qualified stock options, and a slight increase in the liability for unrecognized tax benefits related to uncertain tax positions. Unrecognized Tax Benefits The total liability for gross unrecognized tax benefits increased $146,000 during the three months ended September 30, 2013 to $8.4 million from $8.2 million at June 30, 2013 and is included in other liabilities on our condensed consolidated balance sheets. All of this amount would affect the effective tax rate on income from continuing operations, if recognized. The balance of interest and penalties accrued related to unrecognized tax benefits as of September 30, 2013 was $918,000 and increased by $5,000 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 (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 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 to our condensed consolidated financial statements. Our case is pending review by the Joint Committee of Taxation, which we anticipate to conclude in our fiscal 2014. 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 (The Act). The Act extends the 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 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.
