Income taxes	16. Income taxes The effective income tax rate for the current period was 25.8% compared with 23.5% for the prior period and reflects the Company's estimate of the annual effective tax rate adjusted for certain discrete items, including the tax impact of differences in the value of share based incentive compensation. The effective tax rate for the first quarter of 2021 was primarily impacted by favorable discrete items which were diluted by higher net income.
