Equity [Text Block] | NOTE 9: STOCKHOLDERS’ EQUITY a. Common stock: Holders of common stock are entitled to one vote per share on all matters to be voted upon by the Company’s stockholders. In the event of a liquidation, dissolution or winding up of the Company, holders of common stock are entitled to share ratably in all of the Company’s assets. The Board of Directors may declare a dividend out of funds legally available therefore and the holders of common stock are entitled to receive ratably any such dividends. Holders of common stock have no preemptive rights or other subscription rights to convert their shares into any other securities. b. Preferred stock: The Company is authorized to issue up to 5,000,000 shares of “blank check” preferred stock, par value $0.001 per share. Such preferred stock may be issued by the Board of Directors from time to time in one or more series. These series may have designations, preferences and relative, participating, optional or other special rights and any qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, exchange rights, voting rights, redemption rights (including sinking and purchase fund provisions), and dissolution preferences as may be determined by the Company’s Board of Directors. c. Share repurchase program: In August 2008, the Company announced that its Board of Directors approved a share repurchase program for up to one million shares of common stock which was further extended by an additional 7,800,000 shares in 2010, 2013, 2014, 2018, 2020, 2023 and November 2024. As of December 31, 2024, 1,024,781 shares of common stock remained authorized for repurchase under the Company’s share repurchase program. d. Employee and non-employee stock plans: The Company has historically granted a mix of stock options, SARs capped with a ceiling and RSUs to employees and non‑employee directors of the Company and its subsidiaries under the Company’s equity plans and provides the right to purchase common stock pursuant to the Company’s 2002 employee stock purchase plan to employees of the Company and its subsidiaries. As of December 31, 2023, and December 31, 2024, there were no outstanding or exercisable SARs left. The options granted under the Company’s stock incentive plans have been granted at the fair market value of the Company’s common stock on the grant date. Options granted to employees under stock incentive plans vest at a rate of 25% of the shares underlying the option after one year and the remaining shares vest in equal portions over the following 36 months, such that all shares are vested after four years. Options granted to non‑employee directors vest 25% of the shares underlying the option on each anniversary of the option grant. A summary of the Company’s stock option activities and related information for the year ended December 31, 2024, is as follows:
|  | Number of options |  |  | Weighted average exercise price |  |  | Weighted average remaining contractual term |  |  | Aggregate intrinsic-value |
Outstanding at the beginning of the year |  |  | 99,425 |  |  | $ | 20.74 |  |  |  | 2.5 |  |  | $ | 316 |
Granted |  |  | 10,600 |  |  |  | 19.61 |  |  |  |  |  |  |  |  |
Exercised |  |  | (26,000 | ) |  |  | 14.77 |  |  |  |  |  |  |  |  |
Forfeited or expired |  |  | — |  |  |  | — |  |  |  |  |  |  |  |  |
Outstanding at the end of the year |  |  | 84,025 |  |  | $ | 22.45 |  |  |  | 2.7 |  |  | $ | 765 |
Exercisable at the end of the year |  |  | 60,475 |  |  | $ | 23.12 |  |  |  | 1.5 |  |  | $ | 510 |
During the year ended December 31, 2022, the Company did not grant stock options. The weighted average fair value at grant date of stock options granted for the year ended December 31, 2023, and 2024 amounted to $11.30 and $10.46, respectively. The total intrinsic value of options and SARs exercised during the years ended December 31, 2022, 2023 and 2024 was $273, $173, and $187 respectively. A RSU award is an agreement to issue shares of the Company’s common stock at the time the award or a portion thereof vests. RSUs granted to employees generally vest in three equal annual installments starting on the first anniversary of the grant date. RSUs granted to non-employee directors would generally vest in two equal annual installments starting on the first anniversary of the grant date. On February 12, 2024, the Compensation Committee of the Board (the “Committee”) granted 33,318, 20,043, 16,399 and 13,535 RSUs, effective as of February 16, 2024, to each of the Company’s Chief Executive Officer (“CEO”), Chief Financial Officer (“CFO”), Chief Operating Officer (“COO”) and Chief Commercial Officer (“CCO”), respectively, pursuant to the Company’s 2011 Stock Incentive Plan (the “2011 Plan”). The RSU grants vest 33.4% on February 16, 2025, 33.3% on February 16, 2026 and 33.3% on February 16, 2027. Also, on February 12, 2024, the Committee granted 49,978, 13,362, 10,932 and 9,023 performance-based restricted stock units (“PSUs”), effective as of February 16, 2024, to each of the Company’s CEO, CFO, COO and CCO, respectively, pursuant to the 2011 Plan. The performance goals for the PSUs with specified weighting are as follows:
Weighting | Goals
50% | Vesting of the full 50% of the PSUs occurs if the Company achieves the 2024 license and related revenue target approved by the Board (the “2024 License Revenue Target”). The vesting threshold is achievement of 90% of the 2024 License Revenue Target. If the Company’s achievement of the 2024 License Revenue Target is above 90% but less than 99% of the 2024 License Revenue Target, 91% to 99% of the eligible PSUs would be subject to vesting. If the Company’s actual result exceeds 100% of the 2024 License Revenue Target, every 1% increase of the 2024 License Revenue Target, up to 120%, would result in an increase of 2% of the eligible PSUs for the Company’s CFO, COO and CCO and an increase of 3% of the eligible PSUs for the Company’s CEO.
25% | Vesting of the full 25% of the PSUs occurs if the Company achieves positive total shareholder return whereby the return on the Company’s stock for 2024 is greater than the S&P Semiconductors Select Industry index (the “S&P index”). The vesting threshold is if the return on the Company’s stock for 2024 is at least 90% of the S&P index. If the return on the Company’s stock, in comparison to the S&P index, is above 90% but less than 99% of the S&P index, 91% to 99% of the eligible PSUs would be subject to vesting. If the return on the Company’s stock exceeds 100% of the S&P index, every 1% increase in comparison to the S&P index, up to 120%, would result in an increase of 2% of the eligible PSUs for the Company’s CFO, COO and CCO and an increase of 3% of the eligible PSUs for the Company’s CEO.
25% | Vesting of the full 25% of the PSUs occurs if the Company achieves positive total shareholder return whereby the return on the Company’s stock for 2024 is greater than the Russell 2000 index (the “Russell index”). The vesting threshold is if the return on the Company’s stock for 2024 is at least 90% of the Russell index. If the return on the Company’s stock, in comparison to the Russell index, is above 90% but less than 99% of the Russell index, 91% to 99% of the eligible PSUs would be subject to vesting. If the return on the Company’s stock exceeds 100% of the Russell index, every 1% increase in comparison to the Russell index, up to 120%, would result in an increase of 2% of the eligible PSUs for the Company’s CFO, COO and CCO and an increase of 3% of the eligible PSUs for the Company’s CEO.
Accordingly, assuming maximum achievement of the performance goals set forth above, PSUs representing an additional 60%, meaning an additional 29,986, would be eligible for vesting of the Company’s CEO, and an additional 40%, meaning an additional 5,344, 4,372 and 3,609, would be eligible for vesting for each of the Company’s CFO, COO and CCO, respectively. In 2024, the Company achieved 96% of the 2024 License Revenue Target, a positive total shareholder return whereby the return on the Company’s stock for 2024 was higher by 118% than the S&P index, and a positive total shareholder return whereby the return on the Company’s stock for 2024 was higher by 117% than the Russell index, so based on the PSU award conditions, the Company’s CEO, CFO, COO and CCO received 62,170, 15,446, 12,637 and 10,430 PSUs, respectively. The PSUs vest 33.4% on February 16, 2025, 33.3% on February 16, 2026 and 33.3% on February 16, 2027, and only to the extent that the applicable service-based vesting requirements are satisfied. A summary of the Company’s RSU and PSU activities and related information for the year ended December 31, 2024, is as follows:
|  | Number of RSUs and PSUs |  |  | Weighted average grant-date fair value |
Unvested as at the beginning of the year |  |  | 1,281,751 |  |  | $ | 24.97 |
Granted |  |  | 917,455 |  |  |  | 20.14 |
Vested |  |  | (405,205 | ) |  |  | 31.27 |
Forfeited |  |  | (190,493 | ) |  |  | 21.55 |
Unvested at the end of the year |  |  | 1,603,508 |  |  | $ | 21.01 |
Stock Plans As of December 31, 2024, the Company maintains the Company’s 2011 Stock Incentive Plan (the “2011 Plan”). As of December 31, 2024, options, SARs, RSUs and PSUs to purchase 232,033 shares of common stock were available for grant under the 2011 Plan. 2011 Stock Incentive Plan The 2011 Plan was adopted by the Company’s Board of Directors in February 2011 and stockholders on May 17, 2011. The 2011 Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the Internal Revenue Code, nonqualified stock options, restricted stock, RSUs, dividend equivalent rights and stock appreciation rights. Officers, employees, directors, external consultants and advisors of the Company and those of the Company’s present and future parent and subsidiary corporations are eligible to receive awards under the 2011 Plan. Under current U.S. tax laws, incentive stock options may only be granted to employees. The 2011 Plan permits the Company's Board of Directors or a committee thereof to determine how grantees may pay the exercise or purchase price of their awards. Unless sooner terminated, the 2011 Plan is effective until April 2030. The Company’s Board of Directors or a committee thereof has authority to administer the 2011 Plan. The Company’s Board of Directors has the authority to adopt, amend and repeal the administrative rules, guidelines and practices relating to the 2011 Plan and to interpret its provisions. 2002 Employee Stock Purchase Plan (“ESPP”) The ESPP was adopted by the Company’s Board of Directors and stockholder in July 2002. The ESPP is intended to qualify as an “Employee Stock Purchase Plan” under Section 423 of the U.S. Internal Revenue Code and is intended to provide the Company’s employees with an opportunity to purchase shares of common stock through payroll deductions. An aggregate of 3,450,000 shares of common stock (subject to adjustment in the event of future stock splits, future stock dividends or other similar changes in the common stock or the Company’s capital structure) are reserved for issuance. As of December 31, 2024, 207,933 shares of common stock were available for future issuance under the ESPP. All of the Company’s employees who are regularly employed for more than five months in any calendar year and work 20 hours or more per week are eligible to participate in the ESPP. Non-employee directors, consultants, and employees subject to the rules or laws of a foreign jurisdiction that prohibit or make impractical their participation in an employee stock purchase plan are not eligible to participate in the ESPP. The ESPP designates offer periods, purchase periods and exercise dates. Offer periods generally will be overlapping periods of 24 months. Purchase periods generally will be six-month periods. Exercise dates are the last day of each purchase period. In the event the Company merges with or into another corporation, sells all or substantially all of the Company’s assets, or enters into other transactions in which all of the Company’s stockholders before the transaction own less than 50% of the total combined voting power of the Company’s outstanding securities following the transaction, the Company’s Board of Directors or a committee designated by the Board may elect to shorten the offer period then in progress. The price per share at which shares of common stock may be purchased under the ESPP during any purchase period is the lesser of:
| ● | 85% of the fair market value of common stock on the date of grant of the purchase right, which is the commencement of an offer period; or
| ● | 85% of the fair market value of common stock on the exercise date, which is the last day of a purchase period.
The participant’s purchase right is exercised in the above noted manner on each exercise date arising during the offer period unless, on the first day of any purchase period, the fair market value of common stock is lower than the fair market value of common stock on the first day of the offer period. If so, the participant’s participation in the original offer period will be terminated, and the participant will automatically be enrolled in the new offer period effective the same date. The ESPP is administered by the Board of Directors or a committee designated by the Board, which will have the authority to terminate or amend the plan, subject to specified restrictions, and otherwise to administer and resolve all questions relating to the administration of the plan. e. Dividend policy: The Company has never declared or paid any cash dividends on its capital stock and does not anticipate paying any cash dividends in the foreseeable future.
