3 terms

Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

Performance Shares financial

"Common | 02/16/2021 | Performance Shares | ISSUER"

Performance shares are a type of company stock given to executives or employees that only become theirs if the company meets specific goals, like hitting certain profits or growth targets. They motivate leaders to work toward the company’s success, because their additional shares depend on achieving these results.

restricted securities regulatory

"notice of proposed sale of restricted securities under Rule 144"

Restricted securities are shares or other investment instruments that come with legal or contractual limits on when and how they can be sold, like stock given to founders or bought in a private offering. Think of them as assets in a locked box that can’t be freely traded until certain conditions — such as a waiting period, company registration, or specific approvals — are met. For investors this matters because restricted securities are less liquid and can affect timing, price, and perceived value when they eventually enter the market.
