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 $15.5 million and $6.0 million for the three months ended June 30, 2019 and 2018, respectively, and the effective tax rate was 19.4% and 9.9%, respectively. The provision for income taxes was $31.6 million and $18.5 million for the six months ended June 30, 2019 and 2018, respectively, and the effective tax rate was 21.1% and 16.2%, respectively.

During the three and six months ended June 30, 2018, we recorded a net tax benefit of $4.8 million and $4.5 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.
