Note 14: Income Taxes

At the end of each quarter, we estimate the effective tax rate expected to be applied for the full year. The effective tax rate is determined by the level and composition of pre-tax income or loss, which is subject to federal, foreign and state and local income taxes. The effective tax rate for the nine months ended September 30, 2019 and 2018 was approximately 28 percent and 27 percent, respectively, which increased primarily due to a reduction in the tax benefit related to share-based compensation awards exercised or vested during the nine months ended September 30, 2019.
