Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company files U.S. federal and state and foreign income tax returns in jurisdictions with varying statutes of limitations. In the normal course of business the Company is subject to examination by taxing authorities throughout the world. These audits include questioning the timing and amount of deductions, the allocation of income among various tax jurisdictions and compliance with federal, state, local and foreign tax laws. The Company is currently undergoing examination of the California Franchise Tax Returns relating to California state income taxes of its operating subsidiary for the years 2008 through 2010. The 2008 through 2012 tax years generally remain subject to examination by federal, state and foreign tax authorities. The Company’s gross amount of unrecognized tax benefits increased from $0.4 million as of December 31, 2012 to $0.6 million as of June 30, 2013, $55,000 of which, if recognized, would affect the company’s effective tax rate. It is difficult to predict the final timing and resolution of any particular uncertain tax position. Based on the Company’s assessment of many factors, the Company does not expect that changes in the liability for unrecognized tax benefits for the next twelve months will have a significant impact on the Company’s consolidated financial position or results of operations. During the year ended December 31, 2012 management assessed the realizability of deferred tax assets based on the available evidence, including a history of taxable income and estimates of future taxable income. Management believes that it is not more likely than not that the deferred tax assets will be realized with respect to US federal and state deferred tax assets, except for certain U.S. state deferred tax assets where the Company’s subsidiary has profitable operations. Accordingly, a valuation allowance was provided with respect to U.S. federal and most U.S. State deferred tax assets. A valuation allowance was also provided with respect to deferred tax assets from its Singapore and Ireland subsidiaries. The Company will continue to evaluate its ability to realize deferred tax assets on a quarterly basis. Significant management judgment is required in determining the provision for income taxes and deferred tax assets and liabilities. In the event that actual results differ from these estimates the Company will adjust these estimates in future periods and, the Company may need to adjust the effective tax rate for the current year. The Company considers the undistributed earnings of its foreign subsidiaries permanently reinvested in foreign operations and has not provided for U.S. income taxes on such earnings. On January 2, 2013, the American Taxpayer Relief Act of 2012 was enacted, which reinstated the federal research tax credit retroactive to January 1, 2012 and extended the credit through December 31, 2013. The 2012 federal research tax credit along with the first six months of 2013 federal research tax credit, which would otherwise have been recognized in the first half of 2013, is fully offset by a valuation allowance.
