Income Taxes

The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings before taxes, adjusted for the impact of discrete quarterly items.

The provision for income taxes was $10.9 million and $8.0 million for the three months ended September 30, 2019 and 2018, respectively, and the effective tax rate was 16.8% and 13.1%, respectively. The provision for income taxes was $42.5 million and $26.5 million for the nine months ended September 30, 2019 and 2018, respectively, and the effective tax rate was 19.8% and 15.1%, respectively.

During the three and nine months ended September 30, 2019, we recorded a tax benefit of $1.0 million due to the impact of federal law changes enacted during the quarter. During the three and nine months ended September 30, 2018, we recorded a net tax charge of $0.4 million and a net tax benefit of $4.1 million, respectively, for the

estimated impact of the 2017 Tax Act. Please refer to Note 16, Income Taxes, to the consolidated financial statements in our 2018 Annual Report for further discussion.
