6.	INCOME TAXES

The provision for income taxes for the three months ended September 30, 2017 and 2016 was less than $0.1 million, or 3.5% of pretax loss, and less than $0.1 million, or 11.9% of pretax loss, respectively. The provision for income taxes for the nine months ended September 30, 2017 and 2016 was $0.2 million, or 0.8% of pretax loss, and $0.2 million, or 1.6% of pretax loss, respectively.

The Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to recover the existing deferred tax assets. In this regard, a significant objective negative evidence was the cumulative losses incurred by the Company in recent years. On the basis of this evaluation, the realization of the Company’s deferred tax assets was not deemed to be more likely than not and, thus, the Company maintained a full valuation allowance on its net deferred tax assets as of September 30, 2017.
