restricted stock units financial

"Represents an award of restricted stock units ("RSU") granted as part of the non-employee director's annual compensation"

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.

RSU financial

"RSUs represent a contingent right to receive one share of the Company's common stock upon vesting"

Restricted stock units (RSUs) are a form of company shares given to employees as part of their compensation, usually with certain restrictions or conditions, such as remaining with the company for a set period. When these restrictions lift, employees receive actual shares that they can sell or hold. For investors, RSUs can impact a company's stock supply and reflect the company's commitment to attracting and retaining talent.

dividend equivalent provisions financial

"This amount includes RSUs received pursuant to the dividend equivalent provisions of the RSU awards"

2020 Omnibus Plan financial

"upon vesting pursuant to the Company's 2020 Omnibus Plan"
