Restricted Stock Units financial

"Each restricted stock unit ("RSU") represents a contingent right to receive one share of the Issuer's Class A Common Stock."

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.

Deferred Restricted Stock Units financial

"Each deferred restricted stock unit ("DRSU") represents a contingent right to receive one share of the Issuer's Class A Common Stock."

Deferred restricted stock units are promises by a company to give employees or executives company shares at a future date, subject to conditions like continued employment or performance targets; the delivery and tax event are intentionally delayed. They matter to investors because they affect when new shares may be issued and how executives are motivated—like a paycheck held in escrow that vests over time, influencing potential share dilution and management behavior.

contingent right financial

"Each restricted stock unit ("RSU") represents a contingent right to receive one share of the Issuer's Class A Common Stock."
