Restricted Stock Units financial

"Each Restricted Stock Unit ("RSU") represents a 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.

dividend equivalent financial

"Reflects additional RSUs granted... pursuant to dividend equivalent sections of the Restricted Stock Units Agreement..."

A dividend equivalent is a payment someone receives that matches the cash dividends paid on a stock, even though they don’t actually hold the shares. It often shows up in stock-based pay or certain derivatives, and matters to investors because it preserves the income value and alters the after-tax return and timing of payouts — think of it like getting a paycheck for the dividends you would have earned if you owned the stock directly.

separation of service financial

"RSUs are fully vested and will be settled in Shares... within 30 days after separation of service."
