The Company has in place a 2021 Equity Incentive Plan, 2010 Equity Incentive Plan and 2008 Equity Incentive Plan ("the Plans"). In general, these plans provide for stock-based compensation to the Company’s employees, directors and non-employees. The plans also provide for limits on the aggregate number of shares that may be granted, the term of grants and the strike price of option awards. 2021 Equity Incentive Plan As part of the 2021 Annual Shareholders Meeting, shareholders approved the adoption of the 2021 Equity Incentive Plan (“2021 Equity Plan”). The purpose of the 2021 Equity Plan is to grant (i) Non-statutory Stock Options; (ii) Incentive Stock Options; (iii) Restricted Stock Awards; and/or (iv) Stock Appreciation Rights (collectively, stock-based compensation) to its employees, directors and non-employees. Total stock awards under the 2021 Equity Plan shall not exceed 2 million shares of common stock. Options and Stock Appreciation Rights expire no later than ten years from the date of grant and the awards vest as determined by the Board of Directors. Options and Stock Appreciation Rights have a strike price not less than 100% of the fair market value of the common stock subject to the option or right at the date of grant. As of April 30, 2023, approximately 1.7 million shares were left to issue under this plan. 2010 Equity Incentive Plan On February 18, 2011, shareholders owning a majority of the issued and outstanding shares of the Company executed a written consent approving the 2010 Equity Incentive Plan (“2010 Equity Plan”). The purpose of the 2010 Equity Plan is to grant (i) Non-statutory Stock Options; (ii) Restricted Stock Awards; and (iii) Stock Appreciation Rights (collectively, stock-based compensation) to its employees, directors and non-employees. Total stock awards under the 2010 Equity Plan shall not exceed 30,000,000 shares of common stock. Options and Stock Appreciation Rights expire no later than ten years from the date of grant and the awards vest as determined by the Board of Directors. Options and Stock Appreciation Rights have a strike price not less than 100% of the fair market value of the common stock subject to the option or right at the date of grant. After February 2021, no more shares were available to be issued from this plan. 2008 Equity Incentive Plan The Company has previously granted (i) Non-statutory Stock Options; (ii) Restricted Stock Awards; and (iii) Stock Appreciation Rights (collectively, stock-based compensation) to its employees, directors and non-employees under a 2008 Equity Incentive Plan (the “2008 Equity Plan”). Such awards may be granted by the Company’s Board of Directors. Options granted under the 2008 Equity Plan expire no later than ten years from the date of grant and the awards vest as determined by the Board of Directors. For stock-based payments to non-employee consultants under the Plans, the fair value of the stock-based consideration issued is used to measure the transaction, as management believes this to be a more reliable measure of fair value than the services received. The fair value of the award is expensed over the period service is provided to the Company; however, it is ultimately measured at the price of the Company’s common stock or the fair value of stock options using the Black-Scholes valuation model on the date that the commitment for performance by the non-employee consultant has been reached or performance is complete, which is generally the vesting date of the award. After 2018, no more shares were available to be issued from this plan. Director Compensation Plan On December 12, 2013, the Compensation Committee of the Board of Directors of the Company adopted changes to the Director Compensation Plan of 2010 (the “Director Plan”) effective December 1, 2013. Under the Director Plan, independent directors of the Company were entitled to an annual award of a five-year option to purchase 8,333 shares of the Company’s common stock, and the Chairman of the Board of the Company was entitled to an annual award of a five-year option to purchase 16,667 shares of the Company’s common stock. Independent directors who serve as chairperson of a committee were also to receive an annual grant of a five-year option to purchase 1,667 shares of the Company’s common stock. During fiscal year 2021, the plan was modified to an annual base compensation of $100,000 for each Board Director which could be taken in either company options or a combination of company options and cash, not to exceed $35,000. The Chairman of the Board’s annual compensation was set at an equivalent of $150,000. Compensation for Independent Directors who serve as chairperson of a committee was set at an equivalent of between $110,000 to $120,000. All options issued under the Director Plan vest quarterly at a rate of 25%. Option grants will typically be issued after the annual shareholder meeting which will generally be held in October of each year. New directors will receive compensation upon joining the Board equal to a pro-rata equivalent for the remainder of the year. Options issued under the Director Plan are now issued pursuant to the 2021 Equity Plan. Stock Option Grants Black-Scholes assumptions used to calculate the fair value of options granted during the years ended April 30, 2023 and 2022 were as follows:
| Year Ended April 30,
| 2023 |  | 2022
Expected term in years | 6 |  | 6
Risk-free interest rates | 2.9% - 3.9% |  | 0.8% - 1.2%
Volatility | 61% - 63% |  | 64% - 66%
Dividend yield | 0% |  | 0%
The weighted average fair value of stock options granted during the years ended April 30, 2023 and 2022, was $4.31 and $5.56, respectively. The Company’s stock options activity and related information as of and for the years ended April 30, 2023 and 2022 is as follows:

Share Repurchase Program On March 29, 2023, the Board of Directors approved a share repurchase program authorizing the Company to purchase up to an aggregate of $5.0 million of the Company’s common stock. The share repurchase program is designed in accordance with Rule 10b-18 of the Exchange Act. The shares may be purchased from time to time in the open market, as permitted under applicable rules and regulations, at prevailing market prices. The timing and amount of repurchases will depend on market conditions, share price, applicable legal requirements and other factors. The program does not obligate the Company to acquire a minimum number of shares. As of April 30, 2023, the Company had purchased approximately 14,000 shares of its common stock, at an average price of $5.11 per share, totaling approximately $74,000 and leaving an available balance of approximately $4.9 million authorized by the Board for use in the program as of that date.
