restricted stock units financial

"Grant of restricted stock units. 100% of the shares subject to the restricted stock unit award shall vest..."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

vest financial

"100% of the shares subject to the restricted stock unit award shall vest on the earlier of..."

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

tax liability financial

"Payment of exercise price or tax liability by delivering securities"

director financial

"provided, in each case, that the awardee continues to serve as a director on such date"
