Income Taxes
Income Taxes	Note 8. Income Taxes The Company recognized income tax benefit of $1.0 million and $5.5 million for the three months ended March 31, 2016 and 2015, respectively, which was computed using the “discrete” (or “cut-off”) method. The income tax benefit for the three months ended March 31, 2016 and March 31, 2015 is principally comprised of a deferred tax benefit generated by the unrealized gain recognized during the quarter on available-for-sale marketable securities, which are included in other comprehensive income. 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 will change accordingly in subsequent periods. For the three months ended March 31, 2016, the deferred tax benefit of $1.0 million is comprised of a $1.3 million deferred tax benefit for unrealized gains for securities that have not been sold net of a pro-rata reversal of a deferred tax benefit of $251,000 recorded in the prior year from the partial sale of these securities during the current period. The deferred tax benefit in the period was further reduced by $149,000 of miscellaneous state income tax and foreign income tax expense as determined for the three month period. The deferred tax benefit of $5.6 million recorded in the three months ended March 31, 2015 was offset by $130,000 of miscellaneous state income tax and foreign income tax expenses. 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 each of March 31, 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 $2.9 million and $2.8 million of unrecognized tax benefits at March 31, 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.

Note 8. Income Taxes

The Company recognized income tax benefit of $1.0 million and $5.5 million for the three months ended March 31, 2016 and 2015, respectively, which was computed using the “discrete” (or “cut-off”) method. The income tax benefit for the three months ended March 31, 2016 and March 31, 2015 is principally comprised of a deferred tax benefit generated by the unrealized gain recognized during the quarter on available-for-sale marketable securities, which are included in other comprehensive income. 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 will change accordingly in subsequent periods.

For the three months ended March 31, 2016, the deferred tax benefit of $1.0 million is comprised of a $1.3 million deferred tax benefit for unrealized gains for securities that have not been sold net of a pro-rata reversal of a deferred tax benefit of $251,000 recorded in the prior year from the partial sale of these securities during the current period. The deferred tax benefit in the period was further reduced by $149,000 of miscellaneous state income tax and foreign income tax expense as determined for the three month period. The deferred tax benefit of $5.6 million recorded in the three months ended March 31, 2015 was offset by $130,000 of miscellaneous state income tax and foreign income tax expenses.

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 each of March 31, 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.
