The following table shows our effective income tax rate for the nine months ended September 30:
20232022
Effective income tax rate26.5 %29.5 %

The decrease in the effective rate for the current year compared to the prior year was primarily due to the impairments of the Rail Russia business and the Specialized Gas Vessels in the prior year, for both of which no tax benefit is allowed. These impacts were partially offset by a benefit related to a reduction in the statutory tax rate of Austria in the prior year. Both years were also impacted by the incremental benefits associated with equity awards vested or exercised during the year, as well as the mix of pre-tax income among domestic and foreign jurisdictions, which are taxed at different rates.
