restricted stock units financial
"shares represented by restricted stock units, or RSUs"
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.

custodial account financial
"shares are held in a custodial account"
A custodial account is an investment or bank account opened and managed by an adult (the custodian) for the benefit of someone who cannot legally control assets, typically a minor. Think of it as a wallet held by a trusted guardian until the beneficiary reaches a legal age: it lets you save and invest on someone’s behalf, affects who makes decisions and who pays taxes, and determines when control of the assets transfers to the beneficiary—details investors watch for tax consequences, ownership rules, and timing of control.
