At my current employer, I receive RSUs (restricted stock units) as a form of bonus. I have received a RSU package as a signing bonus and also my annual bonus is paid in RSUs. So, I needed to learn how these assets work.
Investopedia says:
A restricted stock unit (RSU) is an award of stock shares, usually given as a form of employee compensation. The recipient must meet certain conditions before the restricted stock units are transferred to the owner.
