3 terms

restricted stock units financial

"Represents an award of 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.

dividend reinvestment financial

"The amount includes shares acquired via dividend reinvestment since the date"

Dividend reinvestment is when the money earned from a company's profit sharing, called dividends, is automatically used to buy more shares of that company instead of being received as cash. This process helps investors grow their holdings over time without extra effort, much like using earned interest to buy more of a savings account. It encourages long-term investment growth by continuously increasing the amount of shares owned.

Deferred Compensation Plan for Directors financial

"pursuant to the Amended and Restated Deferred Compensation Plan for Directors."

A deferred compensation plan for directors is an arrangement that lets board members postpone receiving part of their pay until a later date—often retirement or a set future time—so the money can grow or be paid under specified conditions. Think of it like directing a portion of your paycheck into a locked savings account that pays out later; investors care because it creates future cash or stock obligations, signals how the company motivates and retains leadership, and can affect shareholder value through timing of payouts or potential dilution.
