11. Income Taxes

The determination of the annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pretax income in each tax jurisdiction in which we operate and the development of tax planning strategies during the year. In addition, as a global commercial enterprise, our tax expense can be impacted by changes in tax rates or laws, the finalization of tax audits and reviews and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions.

The effective tax rates for the three months ended December 31, 2021 and 2022 were 26.3% and 19.5%, respectively. During the three month period ended December 31, 2021, we recognized a net discrete tax expense of $0.3 million related to equity-based compensation under ASU 2016-09 and changes in prior year tax estimates. During the three month period ended December 31, 2022, we recognized a net discrete tax benefit of $0.4 million related to equity-based compensation under ASU 2016-09 and a benefit of $0.4 million from changes in prior year estimates.

The effective tax rate for the six months ended December 31, 2021 and 2022 was 21.6% for both periods. During the six months ended December 31, 2021, we recognized a net discrete tax benefit of $1.8 million related to equity-based compensation under ASU 2016-09 partially offset by a discrete tax expense for changes in prior year tax estimates of $0.2 million. During the six months ended December 31, 2022, we recognized discrete tax benefit of $0.5 million related to equity-based compensation under ASU 2016-09 and $0.4 million from changes in prior year estimates.
