4 terms

Rule 10b5-1 trading plan regulatory

"This transaction was effected pursuant to a Rule 10b5-1 trading plan adopted"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

restricted stock units financial

"The amount reported includes shares subject to unvested restricted stock units"

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.

Employee Stock Option (Right to Buy) financial

"Employee Stock Option (Right to Buy) reported as a derivative security"

indirect ownership financial

"Common stock held indirectly by 401(k) is reported as indirect ownership"
