Restricted Stock Units financial

"security_title: "Restricted Stock Units" and footnote describing contingent right to receive one share"

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.

weighted average price financial

"The price reported in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

tax withholding obligations financial

"sold to satisfy tax withholding obligations incurred in connection with the vesting of restricted stock units"

contingent right financial

"Each restricted stock unit represents a contingent right to receive one share"

vested or vests quarterly financial

"The award vested or vests quarterly as to 1/16 of the total award"
