indirect ownership financial

"indirect ownership represents shares owned by a limited liability corporation"

beneficial owners financial

"equal beneficial owners of the common stock"

Beneficial owners are the people or entities that actually enjoy the economic benefits and control of shares or other assets, even when legal title is held by someone else such as a broker, custodian or trustee. Investors pay attention because beneficial owners hold the real voting power, receive dividends and can influence strategy and takeover outcomes — like the driver of a car who uses and maintains it while the bank holds the title — so disclosure shows who truly controls and benefits.
