Performance Stock Unit financial

"security_title: "Performance Stock Unit" with underlying Common Stock"

A performance stock unit is a type of reward companies give to employees, usually managers, that depends on how well the company performs over time. If the company hits specific goals, the employee earns shares of stock, like earning a prize for reaching certain levels in a game. It motivates employees to work hard because their rewards are tied to the company's success.

Restricted Stock Unit financial

"security_title: "Restricted Stock Unit" granted to the reporting person"

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.

relative total shareholder return financial

"required relative total shareholder return over the 36-month period"

Relative total shareholder return measures how much an investor’s gain from a company — including stock price changes and dividends — beats or lags a chosen benchmark or peer group over a set time. Think of it as a race: it shows whether the company outpaced rivals or the market, which helps investors and boards judge performance, compare returns fairly, and link results to pay or investment decisions.

Compensation Committee of the Board financial

"upon the determination of the Compensation Committee of the Board"

forfeiture of unachieved PSUs financial

"Reflects the number of performance stock units held after the forfeiture of unachieved PSUs"
