(1)Restricted stock shares include restricted phantom stock units under our Director Deferred Compensation Plan. These phantom stock units confer the economic benefits of owning company stock without the actual ownership, transfer or issuance of any shares. Phantom stock units are subject to a vesting period of one year from the grant date. During the six months ended March 31, 2023, 12,591 restricted phantom stock units were granted and 14,199 restricted phantom stock units vested. (2)The number of restricted stock awards vested includes shares that we withheld on behalf of our employees to satisfy the statutory tax withholding requirements. Performance Units A summary of the status of our performance-vested restricted share units ("performance units") as of March 31, 2023 and changes in non-vested performance units outstanding during the six months then ended is presented below:
(in thousands, except per unit amounts) | Performance Units |  | Weighted-Average Grant Date Fair Value per Unit
Non-vested performance units outstanding at September 30, 2022 | 726 |  |  | $ | 33.67 |
Granted | 144 |  |  | 54.30 |
Vested | (286) |  |  | 43.40 |
Dividend equivalent rights performance units credited and performance factor adjustment 1 | 191 |  |  | 36.10 |
Non-vested performance units outstanding at March 31, 2023 2 | 775 |  |  | $ | 34.51 |
(1)At the end of the Vesting Period, recipients receive dividend equivalents, if any, with respect to the number of vested performance units. The vesting of units ranges from zero to 200 percent of the units granted depending on the Company’s total shareholder return ("TSR") relative to the TSR of the Peer Group on the vesting date. (2)Of the total non-vested performance units at the end of the period, specified performance criteria has been achieved with respect to 225,308 performance units which is calculated based on the payout percentage for the completed performance period. The vesting and number of the remainder of non-vested performance units reflected at the end of the period is contingent upon our achievement of specified target performance criteria. If we meet the specified maximum performance criteria, approximately 379,152 additional performance units could vest or become eligible to vest. Subject to the terms and conditions set forth in the applicable performance share unit award agreements and the 2020 Plan, grants of performance units are subject to a vesting period of three years (the “Vesting Period”) that is dependent on the achievement of certain performance goals. Such performance unit grants consist of two separate components. Performance units that comprise the first component are subject to a three-year performance cycle. Performance units that comprise the second component are further divided into three separate tranches, each of which is subject to a separate one-year performance cycle within the full three-year performance cycle. The vesting of the performance units is generally dependent on (i) the achievement of the Company’s TSR performance goals relative to the TSR achievement of a peer group of companies over the applicable performance cycle, and (ii) the continued employment of the recipient of the performance unit award throughout the Vesting Period. The Vesting Period for performance units granted in November 2019 ended on December 31, 2022 and the performance units eligible to vest were settled in shares of common stock in January 2023.
