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.

derivative security financial

"Exercise or conversion of derivative security"

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.

pecuniary interest financial

"expressly disclaims beneficial ownership except to the extent of his pecuniary interest therein"

fractional shares financial

"Reflects the settlement of fractional shares in cash."

Fractional shares are portions of a whole share of a stock or fund, allowing investors to own less than one full unit. They make it possible to invest a specific dollar amount rather than buy whole shares, like buying a slice of a pizza instead of the entire pie. For investors this lowers the cost barrier, helps with diversification, and lets you reinvest dividends or purchase expensive stocks in small, precise amounts.
