Share-Based Compensation Plans

(12) Share-Based Compensation Plans

 

In 2015, upon approval by the Company’s shareholders, the Company’s 2015 Omnibus Incentive Plan (the “2015 Plan”) became effective. A total of 1,332,036 shares were authorized for issuance under the 2015 Omnibus Incentive Plan, including shares available for awards under the 2006 Stock Incentive Plan remaining at the time that plan terminated, or that were subject to awards under the 2006 Stock Incentive Plan that thereafter terminated by reason of expiration, forfeiture, cancellation or otherwise. If any award under the 2006 Stock Incentive Plan or 2015 Plan expires, is cancelled, terminates unexercised or is forfeited, those shares become again available for grant under the 2015 Plan. The 2015 Plan will terminate ten years after its effective date, in October 2025, but is subject to earlier termination as provided in the 2015 Plan. At subsequent shareholder meetings, including most recently in February 2024, the shareholders approved an aggregate increase to the 2015 Plan of 2,900,000 shares resulting in total shares authorized for issuance of 7,282,036 as of April 30, 2024.

 

On January 18, 2018, the Company’s Board of Directors adopted the Company’s Employment Inducement Incentive Award Plan (the “2018 Inducement Plan”) pursuant to which the Company reserved 25,000 shares of common stock for issuance under the Inducement Plan in accordance with Rule 711(a) of the NYSE American Company Guide. On February 9, 2022, the 2018 Inducement Plan was amended to increase the authorized shares by 250,000 to 275,000.

 

 

Stock Options

 

The Company estimates the fair value of each stock option award granted with service-based vesting requirements, using the Black-Scholes option pricing model, assuming no dividends, and using weighted average valuation assumptions. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected life of the award. The expected life (estimated period of time outstanding) of the stock options granted was estimated using the “simplified” method as permitted by the SEC’s Staff Accounting Bulletin No. 110, Share-Based Payment. Expected volatility is based on the Company’s historical volatility over the expected life of the stock option granted. There were zero and 601,089 shares granted for the periods ended April 30, 2024 and 2023, respectively.

 

   Fiscal year ended April 30,

Risk-free interest rate   N/A    3.5%
Expected dividend yield   N/A    0.0%

During the years ended April 30, 2024 and 2023, the Company granted 4,439,257 and 1,608,681 shares, respectively, subject to service-based, performance, and market condition vesting requirements.
