Income Taxes

For interim income tax reporting we estimate our annual effective tax rate and apply it to our year-to-date ordinary income. Tax jurisdictions with a projected or year-to-date loss for which a tax benefit cannot be realized are excluded from the annualized effective tax rate. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur.

Our effective income tax rate was 24.0% and 31.2% for the three and nine months ended September 30, 2014 and 32.8% and 33.9% for the three and nine months ended September 30, 2013. The decrease in the effective income tax rate is primarily due to settlements within various jurisdictions.
