Income taxes

 

For interim financial reporting, the annual tax rate is based on pre-tax income (loss) before equity in income of joint ventures. We have historically calculated the income tax expense/(benefit) during interim reporting periods by applying a full year estimated Annual Effective Tax Rate (“AETR”) to income (loss) before income taxes, excluding infrequent or unusual discrete items, for the reporting period. For the three months ended March 31, 2024, we determined that using an AETR would not provide a reliable estimate of income taxes due to the forecasting methodology used to project income (loss) before income taxes, resulting in significant changes in the estimated AETR. Thus, we concluded to use a discrete effective tax rate, which treats the year-to-date period as an annual period, to calculate income taxes for the three months ended March 31, 2024.

 

Our effective tax rates were 213.6% and (137.4)% for the three months ended March 31, 2024, and 2023 respectively.

 

Our effective tax rate was impacted primarily due to changes in the mix of taxable profits between jurisdictions with different tax regimes, in particular in Latin America and in our ESSA region.
