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 adjusted, 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 first quarter of 2021 reflects an effective tax rate of 19.3 percent, compared to an effective rate of 14.4 percent for the comparable period in the prior year. The increase in the effective rate is primarily due to higher pre-tax income for the three months ended March 31, 2021, together with lower beneficial permanent items as well as an unfavorable adjustment related to state tax liabilities, recorded as a discrete item. The effective rate in both periods includes the effect of beneficial discrete adjustments related to vesting of restricted stock and restricted stock dividends.
