Restricted stock units ("RSUs") financial
"Restricted stock units ("RSUs") represent contingent rights to receive common stock"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

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.
