Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes The Company recorded a provision for federal, state and foreign income taxes of approximately $1.2 million and a benefit of $175,000 for the three months ended June 30, 2013 and 2014, respectively, and a provision for federal, state and foreign income taxes of approximately $1.2 million and $502,000 for the six months ended June 30, 2013 and 2014, respectively. The tax provision for the three and six months ended June 30, 2014, decreased compared to the prior comparable periods as a result of a loss before income taxes incurred in the United States which offset increased profitability in certain foreign jurisdictions, primarily our Irish subsidiaries, which have significantly lower tax rates than the U.S. statutory rate. Deferred income taxes are provided for the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and operating loss carry-forwards and credits using enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. At each balance sheet date, the Company assesses the likelihood that deferred tax assets will be realized, and recognizes a valuation allowance if it is more likely than not that some portion of the deferred tax assets will not be realized. This assessment requires judgment as to the likelihood and amounts of future taxable income by tax jurisdiction. The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Company’s income tax returns since inception are open to examination by federal, state, and foreign tax authorities. The Company has recorded a liability related to uncertain tax provisions of approximately $304,000 and $484,000 as of December 31, 2013 and June 30, 2014, respectively. The Company’s policy is to record estimated interest and penalty related to the underpayment of income taxes or unrecognized tax benefits as a component of its income tax provision. The Company did not recognize any interest or penalties in its statement of operations during the three or six months ended June 30, 2013. The Company recognized approximately $5,000 of interest expense for the three months ended June 30, 2014.
