The amounts of share-based compensation expenses included in applicable costs of revenues and expense categories and related tax effects are summarized as follows:

On September 7, 2011, the Company’s shareholders approved a long-term incentive plan. The amended and restated plan was amended and restated by extending its duration to September 6, 2022, which was approved by the Company’s shareholders at the annual general meeting held on August 28, 2019. The plan permits the grants of options or RSUs to the Company’s employees, directors and service providers where each unit of RSU represents two ordinary shares of the Company.

On September 28, 2016, the Company’s compensation committee made grants of 1,208,785 RSUs to the Company’s employees. The vesting schedule for the RSUs is as follows: 91.93% of the RSUs grant vested immediately on the grant date which was settled by cash amounting to $9,223 thousand, a subsequent 2.69% will vest on each of September 30, 2017, 2018 and 2019 which will be settled by the Company’s ordinary shares, subject to certain forfeiture events.

The vesting schedule for the RSUs is as follows: 98.68% of the RSUs grant vested immediately on the grant date which was settled by cash amounting to $4,762 thousand, a subsequent 0.44% will vest on each of September 30, 2021, 2022 and 2023 which will be settled by the Company’s ordinary shares, subject to certain forfeiture events.

On September 28, 2021, the Company’s compensation committee made grants of 2,604,545 RSUs to the Company’s employees. The vesting schedule for the RSUs is as follows: 85.63% of the RSUs grant vested immediately on the grant date which was settled by cash amounting to $23,174 thousand, a subsequent 4.79% will vest on each of September 30, 2022, 2023 and 2024 which will be settled by the Company’s ordinary shares, subject to certain forfeiture events.

The amount of compensation expense from the long-term incentive plan was determined based on the estimated fair value and the market price of ADS (one ADS represents two ordinary shares) underlying the RSUs granted on the date of grant, which were $8.30 per ADS, $10.93 per ADS, $5.76 per ADS, $3.44 per ADS and $10.39 per ADS on September 28, 2016, September 29, 2017, September 26, 2018, September 28, 2020 and September 28, 2021, respectively.

RSUs activity under the long-term incentive plan during the periods indicated is as follows:

Employee stock options

On September 23, 2019, the Company's compensation committee approved a plan to grant stock options, the 2019 plan, to certain employees. The 2019 plan authorizes grants to purchase up to 3,000,000 units ADS, representing 6,000,000 shares of the Company's ordinary share. 2,226,690 units of stock option to purchase 2,226,690 units ADS were grant to certain employees at an exercise price of $2.27 on September 30, 2019.

The 2019 plan has two years contractual life and one year vesting period. Based on the vesting schedule, 50% of the options vest half year after the date of grant and 50% of the options vest one year after the date of grant. The Company recognized compensation expenses of $326 thousand and $570 thousand in 2019 and 2020, respectively. Such compensation expense was recorded as cost of revenues, sales and marketing expenses, general and administrative expenses and research and development expenses in the consolidated statements of profit or loss. Income tax benefits of $59 thousand and $103 thousand are realized in the consolidated statements of profit or loss for employee stock options for the year ended December 31, 2019 and 2020, respectively.

During 2020, 114,500 units, 39,000 units and 10,000 units of stock option to purchase 114,500 units, 39,000 units and 10,000 units ADS were grant to certain employees at an exercise price of $2.74, $3.9 and $3.35 on March 31, 2020, August 11, 2020 and September 25, 2020, respectively. The options granted in 2020 were fully vested on October 1, 2020. The Company recognized compensation expenses of $122 thousand and recorded income tax benefits of $29 thousand for employee stock options in the consolidated statements of profit or loss for the year ended December 31, 2020.

The calculated value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that used the weighted average assumptions in the following table. The Company uses the simplified method to estimate the expected term of the options as it does not have sufficient historical share option exercise experience and the exercise data relating to employees of other companies is not easily obtainable. The risk-free rates for the expected term of the options are based on the interest rates of 1 years and 1.5 years U.S. Treasury yield at the time of grant.

Employee stock options

(i)

On January 1, 2016, board of directors of Himax Imaging, Inc. approved a plan to grant stock options, the 2016 plan, to certain employees. The 2016 plan authorizes grants to purchase up to 1,760,000 shares of Imaging Taiwan’ issued ordinary shares held by Himax Imaging, Inc. The exercise price was NT$30 (US$0.9139). Himax Taiwan obtained all Imaging Taiwan’ issued ordinary shares previously held by Himax Imaging, Inc. in March, 2017, in a re-organization of entities under common control, whereby Himax Taiwan assumed the obligation to sell Imaging Taiwan’ ordinary shares once employees exercised the options for the 2016 plan.

The 2016 plan has four years contractual life and three years vesting period. Based on the vesting schedule, 50% of the options vest one and half years after the date of grant and 50% of the options vest three years after the date of grant. Because the exercise price of the options are higher than the estimated fair value of Imaging Taiwan shares at the date of grant, the calculated value of each option award estimated using the Black-Scholes option-pricing model was nil.

The calculated value of option award is estimated on the date of grant using the Black-Scholes option-pricing model that used the weighted average assumptions in the following table. Himax Imaging, Inc. uses the simplified method to estimate the expected term of the options as it does not have sufficient historical share option exercise experience and the exercise data relating to employees of other companies is not easily obtainable. Since Imaging Taiwan’ shares are not publicly traded and its shares are rarely traded privately, expected volatility is computed based on the average historical volatility of similar entities with publicly traded shares. The risk-free rates for the expected term of the option are based on the interest rates of 2 years and 5 years ROC central government bond at the time of grant.

Based on the vesting schedule, 50% of the options vest one and half years after the date of grant and 50% of the options vest three years after the date of grant. The Company had recognized all compensation expenses before 2019.

The calculated value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that used the weighted average assumptions in the following table.
