Income Taxes
Note I: Income Taxes
The current quarter’s effective tax rate is 34.7% of pretax income compared to 36.9% for the prior year quarter. For the current year-to-date period, the effective tax rate is 35.2% compared to 36.0% in the prior year-to-date period. The decrease in effective tax rates is primarily due to an increase in both domestic tax credits and the foreign tax credit on overseas earnings, partially offset by the valuation allowance established for operating losses in our Canada operations during their start-up period.
