Income Taxes

The Company generally records its interim tax provision based upon a projection of the Company's estimated annual effective tax rate ("EAETR"). This EAETR is applied to the year-to-date consolidated pre-tax income to determine the interim provisions for income taxes before discrete items. The effective tax rate ("ETR") each period is impacted by a number of factors, including the relative mix of domestic and international earnings, adjustments to the valuation allowances, and discrete items. The currently forecasted ETR may vary from the actual year-end due to the changes in these factors.

​

The Company's global ETR for the three and nine months ended September 30, 2021 and 2020 were  48%, (11)%, 22%, and 48%, respectively, including discrete tax items. The current year decrease in the ETR was principally due to the combined effect of the discrete tax effect of certain prior period swap losses that are required to be excluded from the EAETR calculation and the overall increase in pre-tax loss.
