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 awards financial
"shares subject to the restricted stock unit awards shall vest at the end of each three full calendar months"
Restricted stock unit awards are company promises to deliver a specific number of shares to employees or service providers in the future once conditions—such as staying with the company for a set time or meeting performance targets—are met. They matter to investors because when the promises convert into actual shares they increase the total share count and can reduce earnings per share, while also aligning recipients’ interests with stock performance much like deferred pay that turns into ownership if goals are met.
unvested restricted stock units financial
"The amount reported includes shares subject to unvested restricted stock units and unvested restricted shares."
unvested restricted shares financial
"includes shares subject to unvested restricted stock units and unvested restricted shares."
tax withholding obligations financial
