The provision for income taxes for the nine months ended September 30, 2017 and 2016 were $25,000 and $80,000, respectively. The difference between the statutory rate and the Company’s effective tax rate is primarily due to the impact of foreign taxes, changes in the valuation allowance on deferred tax assets, and changes in the accruals related to unrecognized tax benefits. As of September 30, 2017 and December 31, 2016, the Company had gross unrecognized tax benefits of approximately $9.3 million and $9.2 million, respectively, of which $349,000 and $364,000, respectively, if recognized, would impact the effective tax rate on income from continuing operations. The Company’s policy is to recognize interest and/or penalties related to unrecognized tax benefits in income tax expense. As of September 30, 2017 and December 31, 2016, the Company had accrued $56,000 and $62,000, respectively, for interest and penalties. The $6,000 reduction in interest and penalties on gross unrecognized tax benefits during the nine months ended September 30, 2017 was primarily attributable to the expiration of the statute of limitations in certain foreign jurisdictions.
