Mar. 31, 2016
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded provisions for income taxes of $7,386,000 and $28,951,000 for the three and nine months ended March 31, 2016, respectively, and $8,136,000 and $30,234,000 for the three and nine months ended March 31, 2015, respectively. The effective tax rate was 30.7% and 30.8% for the three and nine months ended March 31, 2016, respectively, and 26.1% and 28.7% for the three and nine months ended March 31, 2015, respectively. The effective tax rate for the three and nine months ended March 31, 2016 is estimated to be lower than the federal statutory rate primarily due to the reinstatement of the U.S. federal research and development ("R&D") tax credit partially offset by the impact of stock option expenses and additional tax accruals related to foreign operations. On December 18, 2015, the Protecting Americans from Tax Hikes Act of 2015 extended the U.S. federal R&D tax credit permanently from January 1, 2015. As of March 31, 2016, the Company projected a total net tax benefit of $4,384,000 for fiscal year 2016, and $2,770,000 reinstated for fiscal year 2015. As of March 31, 2016, the Company had a liability for gross unrecognized tax benefits of $15,794,000, substantially all of which, if recognized, would affect the Company's effective tax rate. During the three and nine months ended March 31, 2016, there were no material changes in the total amount of the liability for gross unrecognized tax benefits. The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for taxes on the condensed consolidated statements of operations. As of March 31, 2016, the Company had accrued $1,010,000 of interest and penalties relating to unrecognized tax benefits. The Company is subject to U.S. federal income tax as well as income taxes in many state and foreign jurisdictions. In August 2015, the Company met with the Internal Revenue Service in connection with its examination of the Company's federal income tax returns for tax years 2013 and 2014. The Company is also under audit in Taiwan for tax year ended June 30, 2014. The Company does not expect a resolution to be reached regarding either matter during the next twelve months. While management believes that the Company has adequate reserves for all uncertain tax positions, amounts asserted by tax authorities could be greater or less than the Company's current position. Accordingly, the Company's provision on federal, state and foreign tax related matters to be recorded in the future may change as revised estimates are made or the underlying matters are settled or otherwise resolved. The federal statute of limitations remain open in general for tax years 2013 through 2015. The various state statute of limitations remain open in general for tax years 2011 through 2015. The statute of limitations in major foreign jurisdictions remain open for examination in general for tax years 2010 through 2015.
