Son RSU (restricted stock units), muy similar a las stock options pero con distinta fiscalidad. En concreto habla de RSU otorgadas en 2017 que el 3 de noviembre 2019 han vencido, así como las de los próximos años.
Restricted share units were granted on November 3, 2017, with 63,613 vesting on November 3, 2019, 180,000 vesting on each of November 1, 2020 and November 1, 2021 and 116,389 vesting on November 1, 2022.
La definición de RSU por si os apetece leer un poco:
A restricted stock unit (RSU) is compensation issued by an employer to an employee in the form of company stock.
Restricted stock units are issued to an employee through a
vesting plan and distribution schedule after achieving required performance milestones or upon remaining with their employer for a particular length of time. RSUs give an employee interest in company stock but they have no tangible value until vesting is complete. The restricted stock units are assigned a fair market value when they vest. Upon vesting, they are considered income, and a portion of the shares is withheld to pay income taxes. The employee receives the remaining shares and can sell them at his or her discretion.
