Note 8.  Income Taxes

Our effective income tax rates for the first quarters of 2020 and 2019 were 24.3% and 25.0%, respectively. The differences between our effective income tax rates and the U.S. federal statutory rate of 21% were mainly due to state income taxes partially offset by the effects of company-owned life insurance policies.

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted on March 27, 2020. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer’s share of social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. We continue to examine the impacts the CARES Act may have on our business.
