CY2023	mco	Inflation Reduction Act Impact On Etr InflationReductionActImpactOnETR	In August 2022, the U.S. Congress passed the Inflation Reduction Act, which included a corporate minimum tax on book earnings of 15%, an excise tax on corporate share repurchases of 1%, and certain climate change and energy tax credit incentives. The adoption of a corporate minimum tax of 15% did not have a significant impact on Moody’s ETR. The excise tax of 1% on corporate share buybacks is recorded to shareholders' equity and does not have an impact on the Company’s ETR.
