NOTE 9. Income Taxes

The provision for income taxes decreased to $4.8 million in 2018 from $6.1 million in 2017. We provided for income taxes using an effective rate of 23.0% in 2018 and an effective rate of 37.0% in 2017. The 2018 effective tax rate was lower primarily due to the enactment of the U.S. Tax Cuts and Jobs Act (the “Act”) on December 22, 2017, which reduced the US federal corporate tax rate from 35% to 21%. We expect our effective tax rate for the remainder of 2018 will range from 24.5% to 25.5%.

Due to the complexities involved in accounting for the enactment of the Act, the SEC Staff Accounting Bulletin No. 118 (“SAB No. 118”) allows for a one-year period, from the date of enactment, to complete the related income tax accounting for the Act and allows for the use of provisional amounts until that accounting is complete.

The Company recorded provisional amounts in earnings for the year ended December 31, 2017 as certain deferred tax assets and liabilities were remeasured based on the rates at which they are expected to reverse in the future, which is generally 21%. However, we are still analyzing aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts until the federal income tax return for 2017 is filed later this year.
