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, at the end of each successive interim period to the Company's current annual estimated tax rate.

For the three months ended September 30, 2024, the effective rate reflects a provision of 19.4 percent compared to a provision of 21.6 percent for the comparable period in the prior year. For the nine months ended September 30, 2024, the effective rate reflects a provision of 19.8 percent compared to a provision of 20.2 percent for the comparable period in the prior year. The decrease in the effective tax rate is primarily due to the impact of favorable permanent differences.
