Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded provisions for income taxes of $6,369,000 and $7,504,000 for the three months ended September 30, 2016 and 2015, respectively. The effective tax rate was 32.0% and 35.4% for the three months ended September 30, 2016 and 2015, respectively. The effective tax rate for the three months ended September 30, 2016 is estimated to be lower than the federal statutory rate primarily due to the benefit from U.S. federal research and development ("R&D") tax credit and domestic production activities deduction. As of September 30, 2016, the Company had a liability for gross unrecognized tax benefits of $17,080,000, substantially all of which, if recognized, would affect the Company's effective tax rate. During the three months ended September 30, 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 September 30, 2016, the Company had accrued $1,524,000 of interest and penalties relating to unrecognized tax benefits. The Company is subject to United States federal income tax as well as income taxes in many state and foreign jurisdictions. The Company's 2012 and 2013 federal tax returns are currently under the IRS examination. The Company has responded to Information Document Requests ("IDRs"), issued by the Internal Revenue Service ("IRS"). No adjustment has been proposed by the IRS as of September 30, 2016.

The Taiwan Tax Authority issued income tax assessments for tax years 2013 and 2014 related to the local income tax exemption regime which the Company has participated in. The Company is currently in the process of appealing the assessments. While management believes that the Company has adequately provided 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 2012 through 2015. The state statute of limitations remain open in general for tax years 2011 through 2015.
