Each share of Common Stock is entitled to one vote. The holders of shares of Common Stock are also entitled to receive dividends whenever funds are legally available, when and if declared by the Board of Directors. Since its inception, the Company has not declared any dividends. b. Reverse stock split On December 9, 2019, the Company’s stockholders approved an amendment to the Company’s Certificate of Incorporation, as amended, to, among other things, effect a reverse stock split at a ratio of one-for-ten. The ratio was determined by the Company’s Board of Directors on December 5, 2019 and the reverse stock split became effective at midnight December 19, 2019. All share and per share amounts included in the consolidated financial statements have been adjusted retrospectively to reflect the effect of the reverse stock split. c. Stock based compensation On December 14, 2006, the Board of Directors adopted the Protalix BioTherapeutics, Inc. 2006 Stock Incentive Plan, as amended (the “Plan”). The Plan has since been amended to, among other things, increase the number of shares of common stock available under the Plan to 5,725,171 shares. The grant of options to Israeli employees under the Plan is subject to the terms stipulated by Sections 102 and 102A of the Israeli Income Tax Ordinance. Each option grant made to an Israeli citizen is subject to the track chosen by the Company, either Section 102 or Section 102A of the Israeli Income Tax Ordinance, and pursuant to the terms thereof, the Company is not allowed to claim, as an expense for tax purposes, the amounts credited to employees as a benefit, including amounts recorded as salary benefits in the Company’s accounts, in respect of options granted to employees under the Plan, with the exception of the work-income benefit component, if any, determined on the grant date. For Israeli non-employees, the share option plan is subject to Section 3(i) of the Israeli Income Tax Ordinance. As of December 31, 2020, 1,493,626 shares of Common Stock remain available for grant under the Plan. For purposes of determining the fair value of the options and restricted stock unit granted to employees and non-employees, the Company’s management uses the fair value of the Common Stock.
