Income Taxes
Income Taxes	Note 8. Income Taxes The Company recognized income tax expense of $1.6 million and $657,000 for the three and six months ended June 30, 2016, respectively, which was computed using the “discrete” (or “cut-off”) method. The income tax expense for the three months ended June 30, 2016 is principally comprised of deferred tax expense generated by the unrealized losses recognized during the quarter on available-for-sale marketable securities and foreign income tax expense. The income tax expense for the six months ended June 30, 2016 is principally comprised of deferred tax expense on the sale of 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. Income tax benefit for the three and six months ended June 30, 2015 was $1.2 million and $6.7 million, respectively, which was computed using the same method and was principally comprised of a deferred tax benefit generated by the unrealized gain recognized during the period on available-for-sale marketable securities, which is included in other comprehensive income. The deferred tax benefit for the three and six months ended June 30, 2015 was partially offset by 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 June 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 $3.0 million and $2.8 million of unrecognized tax benefits at June 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.
