4 terms

performance-based RSU financial

"Represents shares of common stock issued upon vesting of performance-based RSU."

Performance-based RSUs are promises to deliver company stock to employees only if the firm or the individual meets preset financial or operational targets; they convert into actual shares when those goals are achieved. For investors, they matter because they link pay to results—shaping management incentives, affecting future share count and earnings reports, and signaling how confident leadership is about hitting measurable milestones (think of a bonus that only pays out if sales or profit goals are reached).

restricted stock unit financial

"restricted stock unit awards shall vest at the end of each three full calendar months"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

tax withholding obligations financial

"shares that were withheld to satisfy tax withholding obligations upon vesting of restricted stock units"

unvested restricted stock units financial

"The amount reported includes shares subject to unvested restricted stock units."
