Note 5. Income Taxes

On December 22, 2017, the U.S. government enacted tax reform legislation as part of the Tax Cuts and Jobs Act (the "Act") that reduced the corporate income tax rate from 35% to 21% and included a broad range of complex provisions affecting the taxation of businesses. Generally, financial statement recognition of the new legislation would be required to be completed in the period of enactment; however, in response to the complexities of this new legislation, the Securities and Exchange Commission ("SEC") staff issued Staff Accounting Bulletin No. 118 to provide companies with transitional relief. Specifically, when the initial accounting for items under the new legislation is incomplete, the guidance allows (i) recognition of provisional amounts when reasonable estimates can be made, or (ii) continued application of the prior tax law if a reasonable estimate of the effect cannot be made. The SEC staff has provided up to one year from the date of enactment for companies to finalize the accounting for the effects of this new legislation. Although no material changes were made to provisional amounts during the three or nine months ended September 30, 2018, we will continue to refine our estimates related to the new legislation as clarifying guidance and interpretations are issued.

The Company's effective tax rate for the third quarter and first nine months of 2018 was 24.3% and 25.4%, respectively, as compared to 37.8% and 38.3% for the same periods of 2017. The decrease in the tax rate was primarily due to the positive impact of the Act. The Company’s effective tax rate generally exceeds the federal statutory rate due to the impact of state taxes and, to a lesser extent, certain other non-deductible items.
