Income Taxes	Note 10. Income Taxes During the three months ended September 30, 2017 and 2016, we recorded an income tax provision of $1.0 million and $0.1 million, respectively. During the nine months ended September 30, 2017 and 2016, we recorded an income tax benefit of $1.6 million and $0.2 million, respectively. The change in income tax provision and income tax benefit for the three and nine months ended September 30, 2017 was primarily related to excess tax benefits on the exercise of non-qualified stock options and vesting of restricted stock. At December 31, 2016, the Company had $124.0 million of deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income taxes in future years. The Company continues to maintain a valuation allowance against certain deferred tax assets where it is more likely than not that the deferred tax asset will not be realized because of its extended history of annual losses. During the nine months ended September 30, 2017, the statute of limitations expired with respect to certain tax positions for which the Company had previously recorded a reserve. The related tax reserve of $0.3 million and accrued interest of $0.2 million were reversed.
