|Share-Based Payment Arrangement [Text Block]
Effective June 1, 2021, the Company adopted a new stock incentive plan (“New Incentive Plan”) and an employee stock purchase plan (“ESPP”).
The New Incentive Plan authorizes the Board of Directors to administer the New Incentive Plan to provide equity-based compensation in the form of stock options, stock appreciation rights, restricted stock, restricted stock units and dividend equivalents.
The Company currently maintains its existing Share Option Plan and 2015 Stock Incentive Plan (“2015 SIP”). Effective June 1, 2021, no further grants will be made under the Share Option Plan or 2015 SIP, though existing grants under the Share Option Plan will remain in effect in accordance with their terms.
The aggregate number of our common shares, no par value, that may be issued under all awards under the New Incentive Plan is (i) 9,343,242, plus (ii) any of our common shares subject to any outstanding award under our prior plans that, after June 1, 2021, are not purchased or are forfeited or reacquired by us, or otherwise not delivered to the participant due to termination, cancellation or cash settlement of such award subject to the share counting provisions of the New Incentive Plan.
Under both the Share Option Plan and the New Incentive Plan, the exercise price of each option equals the closing trading price of the Company’s stock on the day prior to the grant if the grant is made during the trading day or the closing trading price on the day of grant if the grant is issued after markets have closed. Vesting is provided for at the discretion of the Board of Directors and the expiration of options is to be no greater thanyears from the date of grant.
The Company uses the fair value-based method of accounting for employee awards granted under both plans. The Company calculates the fair value of each stock option grant using the Black-Scholes option pricing model at the grant date. The stock-based compensation cost of the options is recognized as stock-based compensation expense over the relevant vesting period of the stock options using an estimate of the number of options that will eventually vest.
The ESPP allows eligible employees of the Company with an opportunity to purchase Common Shares through accumulated payroll deductions up to a maximumof eligible compensation. The ESPP was implemented by consecutive offering periods with a new offering period commencing on the first trading day on or after February 1 and August 1 each year, or on such other date as the Board of Directors will determine and continuing thereafter until terminated in accordance with the Plan. Unless the Board of Directors provides otherwise, the purchase price will be equal to eighty five percent ( ) of the fair market value of a Common Share on the offering date or the exercise date, whichever is lower. The maximum number of Common Shares available for sale under the ESPP is 1,700,000 Common Shares. The first six-month offering period began on February 1, 2022, and ended on August 1, 2022. There were 10,858 Common Shares issued under the ESPP as of September 30, 2022 ( December 31, 2021 – ). The second six-month period began on August 1, 2022, and will end on February 1, 2023.
Stock option transactions for the nine months ended September 30, 2022, and September 30, 2021, are summarized as follows:
As of September 30, 2022, there was $3.99 million of total unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over an estimated weighted-average period of 1.5 years. As of September 30, 2022, total compensation cost not yet recognized related to grants under the ESPP was approximately $4 thousand, which is expected to be recognized over four months.
The following table presents the weighted average assumptions that were used in the Black ‑Scholes option pricing model to determine the fair value of stock options granted during the period, and the resultant weighted average fair values:
The Company uses historical data to estimate the expected dividend yield and expected volatility of its common shares in determining the fair value of stock options. The expected life of the options represents the estimated length of time the options are expected to remain outstanding.
