INCOME TAXES

Income tax provisions for interim quarterly periods are based on an estimated annual effective income tax rate calculated separately from the effect of significant, infrequent or unusual items related specifically to interim periods. Income tax expense for the

three

months ended

September 30, 2018

was

$0.1

million, an effective tax rate of

1.0%.

Income tax expense for the

nine

months ended

September 30, 2018

was

$1.4

million, an effective tax rate of

6.3%.

The Company did

not

recognize any income tax expense or benefit for the

three

or

nine

months ended

September 30, 2017

because tax losses incurred for the year were fully offset by a valuation allowance against deferred tax assets.

There were

no

uncertain tax positions as of

September 30, 2018.
