Stockholders' Equity Note [Abstract] |
SHAREHOLDERS' EQUITY | NOTE 14: SHAREHOLDERS’ EQUITY A. Description of Ordinary Shares As of December 31, 2024, Tower had 150 million authorized ordinary shares, par value NIS 15.00 each, of which approximately 111.6 million were outstanding. Holders of ordinary shares are entitled to participate equally in the payment of cash dividends and bonus share (stock dividend) distributions, if any, and, in the event of the liquidation of Tower, in the distribution of assets after satisfaction of liabilities to creditors. Each ordinary share is entitled to one vote on all matters to be voted on by shareholders. B. Equity Incentive Plans (1) Tower’s 2013 Share Incentive Plan (the “2013 Plan”) In 2013, the Company adopted a share incentive plan for directors, officers and employees of the Company (“2013 Plan”). Under the 2013 Plan, the Company granted a total of approximately 1.58 million restricted stock units (“RSUs”) to its employees and directors during 2024 and a total of approximately 0.80 million RSUs to its employees and directors during 2023, including the below-described grants to the CEO and directors, with vesting periods of up to three years. These RSUs amounts also include performance based RSUs (“PSUs”) and market based RSUs (“MSUs”). The Company determines compensation expenses of the RSUs based on the closing market price of the ordinary shares on the last trading day immediately prior to the date of grant and amortizes it over the applicable vesting period, taking into consideration achievement, if any, of performance and market criteria. During 2024, the Company's CEO and members of the Board of Directors were awarded the following RSUs under the 2013 Plan: (i) approximately 78.4 thousand time-vested RSUs, 176.3 thousand PSUs and 256.3 thousand MSUs, granted to the CEO, with 33% of such RSUs, PSUs and MSUs to vest at the end of each year for 3 years following the grant date. The total compensation value of these awards was approximately $16,500. As was approved by shareholders in 2019, the grant also included a provision requiring the CEO to own, commencing May 2024, ordinary shares of the Company at a minimum value that equals at least three times his annual base salary as of May 2024 (the “Minimum Holding”). As of December 31, 2024, the CEO is in compliance with the Minimum Holding requirement; (ii) approximately 7.4 thousand time-vested RSUs to the chairman of the Board of Directors (the “Chairman”) for a total compensation value of $300, to vest 33% at the end of each year for 3 years following the grant date; and (iii) approximately 4.9 thousand time-vested RSUs to each of the eight members of the Board of Directors then serving (other than to the Chairman and the CEO), for an aggregate compensation value of $1,600, vesting over a two-year period, with 50% vesting on the first anniversary of the date of grant and 50% on the second anniversary of the date of grant. As was approved by shareholders in 2020, commencing July 2025, the members of the Board will have to own ordinary shares of the Company at a minimum value that equals at least 50% of their annual base fee and the Chairman will have to own ordinary shares of the Company at a minimum value that equals at least 50% of his annual cash compensation (the “BOD Minimum Holding”). The Chairman and the members of the Board have until July 2025 to accumulate the BOD Minimum Holding (whether by conversion of RSUs to ordinary shares or by purchase of ordinary shares), and during such period, until they accumulate the BOD Minimum Holding, they must retain at least 20% of the vested time-based RSUs granted to him/her on or after July 2020. During 2023, the Company's CEO and members of the Board of Directors were awarded the following RSUs under the 2013 Plan: (i) approximately 75.8 thousand time-vested RSUs and 125.0 thousand PSUs granted to the CEO, subject also to time-vesting, with 33% of such RSUs and PSUs to vest at the end of each year for 3 years following the grant date. The total compensation value of these RSUs was approximately $7,500 and also included the Minimum Holding requirement defined above; (ii) approximately 8.0 thousand time-vested RSUs to the Chairman for a total compensation value of $300, to vest 33% at the end of each year for 3 years following the grant date; and (iii) approximately 3.3 thousand time-vested RSUs to each of the seven members of the Board of Directors then serving (other than to the Chairman and the CEO), for an aggregate compensation value of $875, vesting over a two-year period, with 50% vesting on the first anniversary of the date of grant and 50% on the second anniversary of the date of grant. During 2022, the Company's CEO and members of the Board of Directors were awarded the following RSUs under the 2013 Plan: (i) approximately 59 thousand time-vested RSUs and 97 thousand PSUs granted to the CEO, subject also to time-vesting, with 33% of such RSUs and PSUs to vest at the end of each year for 3 years following the grant date. Total compensation value of these RSUs was approximately $7,200 and also includes the Minimum Holding requirement defined above; (ii) approximately 6.5 thousand time-vested RSUs to the Chairman for a total compensation value of $300, to vest 33% at the end of each year for 3 years following the grant date; and (iii) approximately 2.7 thousand time-vested RSUs to each of the seven members of the Board of Directors then serving (other than to the Chairman and the CEO), for an aggregate compensation value of $875, vesting over a two-year period, with 50% vesting on the first anniversary of the date of grant and 50% on the second anniversary of the date of grant. The grants during 2023 and 2022 to the Chairman and the members of the Board also include the BOD Minimum Holding requirement defined above. (2) RSUs awards
