beneficially owned financial

"The number of securities shown to be beneficially owned reflects an adjustment"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

indirect ownership financial

"ownership_type":"indirect","ownership_code":"I""

limited partnership financial

"By JAMEB, LP, a limited partnership jointly owned by Reporting Person"

A limited partnership is a legal business structure with two types of partners: at least one general partner who runs the business and bears full legal responsibility, and one or more limited partners who contribute money, share profits, and have liability capped at their investment. For investors, it matters because it separates control from financial exposure — like putting money into a store without managing it — and affects how returns, risks, taxes and transferability of ownership are handled.

irrevocable trust financial

"By the James A. Burke 2012 Irrevocable Trust, dated 12/03/2012"

An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
