INCOME TAXES
Effective Tax Rate
Our quarterly income tax expense is measured using an estimated annual effective income tax rate. The comparison of effective income tax rates between periods may be significantly affected by discrete items recognized during the periods, the level and mix of earnings by tax jurisdiction and permanent differences.
The Company recorded income tax expense of $2.7 million and $6.5 million for the three and six months ended June 30, 2017, respectively, and $3.5 million and $7.4 million for the three and six months ended July 1, 2016, respectively, representing effective income tax rates of 32.9% and 35.0%, respectively, and 36.7% and 37.0%, respectively. The effective income tax rates may vary from the federal statutory rate of 35.0% due to state taxes, the tax effect of stock-based compensation, and other permanent book-tax differences.
Uncertain Tax Provisions
As of June 30, 2017 and December 31, 2016, unrecognized tax benefits from uncertain tax positions were $0.4 million. Management believes the uncertain tax positions will be resolved in the next twelve months.
