5 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 units financial

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

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.

tax withholding obligations financial

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

By Trust financial

"Common Stock holding entry shows indirect ownership nature as "By Trust"."

grant, award, or other acquisition financial

"Transaction code A is described as "Grant, award, or other acquisition"."
