Income Taxes
Income Taxes	Note 8. Income Taxes The Company recorded an income tax benefit of $5.5 million and expense of $75,000 for the three months ended March 31, 2015 and 2014, respectively, which was computed using the “discrete” (or “cut-off”) method. The income tax benefit for the period ended March 31, 2015 is principally comprised of a deferred tax benefit generated by the unrealized gain recognized in this period on available-for-sale marketable securities, which is included in other comprehensive income. The intraperiod tax allocation rules limit the amount of benefit recognized to the extent of current period pre-tax loss. Thus, if the Company recognizes pre-tax losses in subsequent periods in 2015 and the related unrealized gain in other comprehensive income is retained, additional benefits may be recognized. The deferred tax benefit recorded in the current quarter was offset by $130,000 of miscellaneous state income tax and foreign income tax expense on earnings of our foreign subsidiaries. The income tax expense for the period ended March 31, 2014, was principally comprised of state income taxes and foreign taxes. The difference between the income tax expense actually recorded and the statutory rate applied to the Company’s loss before income taxes was primarily due to the impact of nondeductible stock-based compensation expenses and nondeductible meals and entertainment for the three months ended March 31, 2014. Based on all available objective evidence, the Company believes that it is more likely than not that its net deferred tax assets will not be fully realized. Accordingly, the Company maintained a valuation allowance against all of its net deferred tax assets as of both March 31, 2015 and December 31, 2014. 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 $1.6 million of unrecognized tax benefits at both March 31, 2015 and December 31, 2014. The Company does not anticipate a material change to its unrecognized tax benefits over the next twelve months that would affect its effective tax rate. Unrecognized tax benefits may change during the next twelve 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 2000 through 2015 in U.S. federal and state jurisdictions, and for the years 2010 through 2015 in foreign jurisdictions.
