All references in this report to historical Common Share prices, numbers of Common Shares, and earnings per share calculations have been presented to reflect the effect of the Reverse Stock Split.

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. Effective June 1, 2021, no further grants have been made under the Share Option Plan, though existing grants under the Share Option Plan 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) 691,400, 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 than ten years 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 to purchase Common Shares through accumulated payroll deductions up to a maximum 15% of 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 (85%) 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 113,333 Common Shares. The first six-month offering period began on February 1, 2022, and ended on August 1, 2022. There were 724 Common Shares issued under the ESPP as of December 31, 2022. The second six-month period began on August 1, 2022, and ended on February 1, 2023. The third six-month period began on February 2, 2023, and ended on August 1, 2023. There were 5,991 and 724 Common Shares issued under the ESPP during the nine months ended September 30, 2023 and September 30, 2022, respectively.

During the nine months ended September 30, 2022, the option agreements of one Company officer were modified as part of a separation and release agreement. 56,765 vested options, with exercise prices ranging from $20.10 to $103.65, were allowed to continue to be exercisable for an additional 12-month period, and also 31,810 options that would have expired unvested, were allowed to continue to vest for a 12-month period. As there was no service requirement, during the nine months ended September 30, 2022, the Company recorded $67 thousand in additional compensation related to these modifications.

As of September 30, 2023, there was $1.61 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 1.47 years. As of September 30, 2023, 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 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.

The Company has a stock incentive plan (SIP) pursuant to which the Board may grant stock-based awards comprised of restricted stock units or dividend equivalents to employees, officers, consultants, independent contractors, advisors and non-employee directors of the Company. Each restricted stock unit ("RSU") is automatically redeemed for one Common Share of the Company upon vesting. During the nine-month period ended September 30, 2023, the Company granted 38,000 RSUs with immediate vesting and an exercise price of $9.90 (the "2023 RSU Grant"). On February 6, 2023, all of these RSUs were redeemed for 38,000 Common Shares. No RSUs were granted in the nine months ended September 30, 2022. The following table presents the vesting and redemption of the RSUs granted in the three months and nine months ended September 30, 2023 and September 30, 2022.
