Restricted Stock Units financial

"Restricted stock units ("RSUs") represent contingent rights to receive common stock"

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.

Disposition to issuer financial

Exercise or conversion of derivative security financial

cash-settled financial

"Reflects RSUs that were cash-settled, per the terms of the compensation program"

Cash-settled describes a financial contract that is resolved by paying the monetary difference between agreed and actual prices, instead of delivering the underlying asset. For investors, it matters because it simplifies trades—like settling a bet with cash rather than handing over the item—and affects liquidity, tax treatment, and counterparty exposure, since you receive or pay only the value change rather than owning or transferring the actual security or commodity.
