We maintain stock incentive plans (collectively, the “Plans”) for the benefit of certain of our officers, directors and employees.

The following table provides total share-based compensation expense by type of award:


	Three Months Ended September 30,
(in millions)	2023		2022
Restricted share unit expense	$	21	$	17

Performance share unit expense	8		6
Total share-based compensation	$	29	$	23

The total tax benefit related to share-based compensation was $4 million and $3 million for the three months ended September 30, 2023 and 2022, respectively.

Restricted share units granted under the Plans generally vest in equal annual installments over three years. Restricted share units accrue cash dividend equivalents that are payable upon vesting of the awards.

The following table summarizes all transactions related to restricted share units under the Plans:

Based on the extent to which the targets are achieved, vested shares may range from zero to 234 percent of the target award amount for both the fiscal 2022 and 2023 grants and zero to 240 percent of the target award for the fiscal 2024 grant.
