custodial account financial

"held by a child through 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.

TTE technical

"Gary Charles Robb TTE Robb Revocable Trust"

Time-to-event (TTE) measures how long it takes for a specific outcome to occur, such as disease progression, hospitalization, or death, in a clinical study. Investors care because TTE shows how quickly a drug or treatment produces meaningful results versus alternatives, similar to timing how long different cars take to reach the same speed; faster or delayed outcomes can affect a drug’s market potential, regulatory prospects, and future revenue.
