Income Taxes	Note 8. Income Taxes The Company recognized an income tax benefit of $193,000 and income tax expense of $464,000 for the three and nine months ended September 30, 2016, respectively, which was computed using the “discrete” (or “cut-off”) method. The income tax benefit and income tax expense for the three and nine months ended September 30, 2016, respectively, was primarily comprised of the intraperiod tax allocation of the deferred tax impact for available-for-sale marketable securities and foreign income tax expense. The intraperiod tax allocation rules limit the amount of benefit recognized to the lesser of year-to-date pre-tax loss or year-to-date unrealized gain recognized on available-for-sale marketable securities included in other comprehensive income. Therefore, the tax benefit or expense will change accordingly in subsequent periods. For the three and nine months ended September 30, 2015, the Company recorded income tax expense of $6.3 million and an income tax benefit of $410,000, respectively, which was computed using the discrete (or “cut-off”) method. The income tax expense and income tax benefit for the three and nine months ended September 30, 2015, respectively, was primarily comprised of the intraperiod tax allocation of the deferred tax impact for available-for-sale marketable securities, miscellaneous state income tax and foreign tax expense on earnings of the Company’s foreign subsidiaries. Based on all available objective evidence, the Company believes that it is still more likely than not that its net deferred tax assets will not be fully realized. Accordingly, the Company maintains a valuation allowance against all of its net deferred tax assets as of both September 30, 2016 and December 31, 2015. The Company will continue to maintain a full valuation allowance until there is sufficient evidence to support recoverability of its deferred tax assets. The Company had $3.1 million and $2.8 million of unrecognized tax benefits at September 30, 2016 and December 31, 2015, respectively. The Company does not anticipate a material change to its unrecognized tax benefits over the next 12 months that would affect its effective tax rate. Unrecognized tax benefits may change during the next 12 months for items that arise in the ordinary course of business. Accrued interest and penalties related to unrecognized tax benefits are recognized as part of the Company’s income tax provision in its condensed consolidated statements of operations. The statute of limitations remain open for the years 2001 through 2016 in U.S. federal and state jurisdictions, and for the years 2010 through 2016 in foreign jurisdictions.
