b.Ordinary shares: The ordinary shares of the Company confer upon the holders the right to receive notices of and to participate and vote in general meetings of the Company, rights to receive dividends and rights to participate in distribution of assets upon liquidation. c.Share-based compensation: On January 1, 2021, the Company's ESPP became effective. The ESPP enables eligible employees and eligible employees of designated subsidiaries to elect to have payroll deductions made during a six-month offering period in an amount not exceeding 15% of the gross base compensation which the employees receive. The total number of ordinary shares initially reserved under the ESPP as of January 1, 2021 was 125,000 shares ("the ESPP Share Pool"). In connection with establishing the ESPP, the Company correspondingly reduced the number of shares available under the Company's 2014 share incentive plan (the "2014 Plan") by 125,000. On January 1 of each year between 2022 and 2026 the ESPP Share Pool will be increased by a number of ordinary shares equal to the lowest of (i) 1,000,000 shares, (ii) 1% of the Company’s outstanding shares on December 31 of the immediately preceding calendar year, and (iii) a lesser number of shares determined by the Company’s board of directors. As of December 31, 2022, 6,898 ordinary shares were reserved for issuance under the ESPP. On January 1, 2023, the aggregate number of ordinary shares reserved for issuance under the ESPP was increased by 200,000 shares. The applicable purchase price will be no less than 85% of the lesser of the fair market value of the Company’s ordinary shares on the first day or the last day of the purchase period. Under the 2014 Plan and ESPP, options, RSUs, PSUs and other share-based awards may be granted to employees, officers, non-employee consultants and directors of the Company. Under the 2014 Plan and ESPP, as of December 31, 2022, an aggregate number of 1,303,628 ordinary shares were reserved for future grant. Any share underlying an award that is cancelled, terminated or forfeited for any reason without having been exercised will automatically be available for grant under the 2014 Plan. The total share-based compensation expense related to all of the Company's equity-based awards, recognized for the years ended December 31, 2020, 2021 and 2022 is comprised as follows:

The expected volatility of the Company's common stock is based on the Company's historical volatility. The expected option term represents the period of time that options granted are expected to be outstanding, based upon historical experience. The Company has historically not paid dividends and has no foreseeable plans to pay dividends and, therefore, uses an expected dividend yield of zero in the option pricing model. The risk-free interest rate is based on the yield of U.S. treasury bonds with equivalent terms. The following tables sets forth the parameters used in computation of the options and ESPP compensation to employees for the years ended December 31, 2020, 2021 and 2022:
