Schedule 13G regulatory

"MacroGenics, Inc. reported a Schedule 13G showing that Millennium Management LLC"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

shared dispositive power regulatory

"Shared Dispositive Power 3,435,504.00 is shown on the cover entries"

shared voting power regulatory

"Shared Voting Power 3,435,504.00 is shown on the cover entries"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
