The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to reducing the U.S. federal corporate tax rate from 35% to 21%. SAB No. 118 provides guidance on accounting for the tax effects of the Tax Act and a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under the FASB’s Accounting Standard Codification (“ASC”) 740 - Income Taxes (“ASC 740”). In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. We did not record any adjustments to our provisional estimate during the first three months of 2018 and continue to evaluate the Tax Act.

The Company had an uncertain tax position of $0.6 million as of March 31, 2018 and December 31, 2017. The Company does not have a valuation allowance as of March 31, 2018 and December 31, 2017.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense in the consolidated statements of operations and statements of comprehensive income (loss). For the three months ended March 31, 2018 and 2017, the Company did not recognize any expense for accrued interest and penalties related to unrecognized tax benefits. For the three months ended March 31, 2018, the Company recognized no income tax expense related to an uncertain tax position. For the three months ended March 31, 2017, the Company recognized less than $0.1 million income tax expense related to an uncertain tax position.
