Share-based Payments

3 Months Ended

Dec. 31, 2024

Share-Based Payment Arrangement [Abstract]

The Company grants stock units to employees under its Performance Earnings Program (PEP), whereby units are earned and issued dependent upon meeting established cumulative performance objectives and vest over a three-year service period. Additionally, the Company issues restricted stock units to employees and directors which are earned based on service conditions. The grant date fair value of PEP awards and restricted stock unit awards is primarily based on that day’s closing market price of the Company’s common stock.

Restricted stock units and PEP unit activity for the three months ended December 31 was as follows:
