Performance-Based Restricted Stock Units financial
"award of performance-based restricted stock units"
Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.
volume-weighted average closing price financial
"based on the volume-weighted average closing price per share"
The volume-weighted average closing price is the average of a security’s closing prices over a chosen period, where each day’s closing price is given more influence if more shares traded that day. Think of it like calculating the average price you paid for apples but counting each day’s basket size so large purchases matter more than small ones. Investors use it to see the fairer, trade-weighted trend of price movement and to reduce the skew from low-volume days.
cash settle financial
"elected to cash settle the earned PSUs"
Employee Stock Purchase Plan financial
"stock purchased under an Employee Stock Purchase Plan (ESPP)"
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
