2.23 Employee equity incentive plans
Under an equity participation plan, the Board of Directors can grant entitlements for employee shares to members of the Group Management. If the employee remains with the company for the duration of the three-year vesting period, the participants in the plan are entitled to receive one employee share per entitlement. If the employee leaves the firm before the end of the vesting period, any entitlement for employee shares is usually extinguished. When the entitlements for employee shares are allocated, they are valued on the basis of the share price and taking into account the likelihood that the employee remains with the company until the end of the vesting period. The personnel expenditure is distributed linearly over the vesting period and an accrual is recognized directly in equity. Changes in the estimates of employees granted entitlements remaining at the company are included, in aggregate form, in the calculation of the expenditure to be recorded.
As part of the equity bonus plan, the members of the Group Management and the senior management can elect, on a voluntary basis, to receive a portion of their annual bonus in the form of restricted shares at a preferential price set by the Board of Directors. The Board of Directors determines each year the portion of the bonus that can be awarded in shares, the duration of the vesting period and the preferential price. This share-based compensation is valued at the average share price for the month of December and charged to personnel expenditure. The voting rights and dividend rights are transferred with the transfer of the shares to the beneficiary. With regard to the 2018 equity bonus plan, the Board of Directors has determined that the members of the Group Management and the senior mana§gement may receive 1/3 of their bonus in the form of shares with a vesting period of 3 years and at an equivalent price of +20% of that part of the bonus they are entitled to receive in shares.
