9.  INCOME TAXES

The Company determines its periodic income tax provision based upon the current period income and the annual estimated tax rate for the Company adjusted for discrete items including tax credits and changes to prior year estimates. The estimated tax rate is revised, if necessary, as of the end of each successive interim period during the fiscal year to the Company’s current annual estimated tax rate.

Income tax provision for the third quarter of 2020 reflects an effective tax rate of 21.8 percent, compared to an effective rate of 19.8 percent for the comparable period in the prior year. For the nine months ended September 30, 2020, the effective tax rate was 19.0 percent compared to 18.2 percent for the comparable period in the prior year. The effective tax rates in 2020 and 2019 include the effect of beneficial permanent differences including discrete adjustments related to vesting of restricted stock and the associated dividends. The increase in the 2020 effective tax rate is primarily due to a detrimental provision to return discrete adjustment in the third quarter of 2020 compared to a beneficial discrete adjustment in the same period of 2019.

The Coronavirus Aid, Relief and Economic Security (CARES) Act, enacted into law on March 27, 2020, has been evaluated in the Company's tax provision and there is no impact to the tax provision at this time. The impact of the CARES Act will continue to be evaluated throughout 2020.
