On November 4, 2021, the Board authorized a share repurchase plan (Fiscal 2022 Repurchase Plan), pursuant to which we may purchase in open market transactions, from time to time over the 12-month period commencing November 12, 2021, up to an aggregate of $350 million of our Common Shares.

We estimate the fair value of stock options using the Black-Scholes option-pricing model or, where appropriate, the Monte Carlo pricing model, consistent with the provisions of ASC Topic 718, “Compensation—Stock Compensation” (Topic 718) and SEC Staff Accounting Bulletin No. 107. The option-pricing models require input of subjective assumptions, including the estimated life of the option and the expected volatility of the underlying stock over the estimated life of the option. We use historical volatility as a basis for projecting the expected volatility of the underlying stock and estimate the expected life of our stock options based upon historical data.

We believe that the valuation techniques and the approach utilized to develop the underlying assumptions are appropriate in calculating the fair value of our stock option grants. Estimates of fair value are not intended, however, to predict actual future events or the value ultimately realized by employees who receive equity awards.

For the periods indicated, the weighted-average fair value of options and weighted-average assumptions estimated under the Black-Scholes option-pricing model were as follows:


	Three Months Ended March 31,						Nine Months Ended March 31,
	2023			2022			2023			2022
Weighted–average fair value of options granted	$	7.94		$	8.31		$	6.61		$	9.08

During the three and nine months ended March 31, 2023, we granted zero and 1,000,000 performance options, respectively (during the three and nine months ended March 31, 2022—nil, respectively).

For the period in which performance options were granted, the weighted-average fair value of performance options and weighted-average assumptions estimated under the Monte Carlo pricing model were as follows:


	Nine Months Ended March 31,
	2023
Weighted–average fair value of options granted	$	8.09

We incentivize certain eligible employees, in part, with long-term compensation pursuant to our LTIP. The LTIP is a rolling three-year program that grants eligible employees a certain number of target Performance Share Units (PSUs) and/or Restricted Share Units (RSUs). Target PSUs become vested upon the achievement of certain financial and/or operational performance criteria (the Performance Conditions) that are determined at the time of the grant. RSUs become vested when an eligible employee remains employed throughout the vesting period.

PSUs and RSUs granted under the LTIP have been measured at fair value as of the effective date, consistent with Topic 718, and will be charged to share-based compensation expense over the remaining life of the plan. We estimate the fair value of PSUs using the Monte Carlo pricing model and RSUs have been valued based upon their grant date fair value. Stock options granted under the LTIP have been measured using the Black-Scholes option-pricing model, consistent with Topic 718.

Grants made in Fiscal 2023 under the LTIP (collectively referred to as LTIP 2025), consisting of PSUs and RSUs, took effect in Fiscal 2023 starting on August 8, 2022. The Performance Conditions for vesting of the PSUs are based solely upon market conditions. The RSUs are employee service-based awards and vest over the life of the LTIP 2025. We expect to settle the LTIP 2025 awards in Common Shares. The LTIP 2025 PSU and RSU awards are eligible to receive dividend equivalent units that vest under the same conditions as the underlying grants.

(1)PSUs are earned based on market conditions and the actual number of PSUs earned, if any, is dependent upon performance and may range from 0 to 200 percent.

For the periods indicated, the weighted-average fair value of PSUs issued under LTIP, and weighted-average assumptions estimated under the Monte Carlo pricing model were as follows:

In addition to the grants made in connection with the LTIP discussed above, from time to time, we may grant RSUs to certain employees in accordance with employment and other non-LTIP related agreements. RSUs (other) vest over a specified contract date, typically two or three years from the respective date of grants.

The DSUs are granted to certain non-employee directors. DSUs are issued under our Deferred Share Unit Plan. DSUs granted as compensation for director fees vest immediately, whereas all other DSUs granted vest at our next annual general meeting following the granting of the DSUs. No DSUs are payable by us until the director ceases to be a member of the Board.

During the three and nine months ended March 31, 2023, we settled 30,273 DSUs, respectively, at a cost of $1.1 million, respectively, (three and nine months ended March 31, 2022—nil DSUs, respectively, at a cost of nil, respectively).
