beneficial ownership financial

"The beneficial ownership calculation relies on the 66,633,321 outstanding shares"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

shared voting power financial

"Shared Voting Power 4,468,123.00"

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.

shared dispositive power financial

"Shared Dispositive Power 4,468,123.00"

parent holding company financial

"If a parent holding company has filed this schedule, pursuant to (ii)(G)"

broker dealer financial

"BofA Securities, Inc., a broker dealer registered under section 15 of the Act"

A broker-dealer is a firm or individual that helps people buy and sell stocks, bonds and other securities (acting as a broker) and may also trade those same securities with its own money (acting as a dealer). It matters to investors because broker-dealers execute trades, hold assets, provide access to markets and research, and can create conflicts of interest — like a market operator that also sells its own goods — so their costs, speed and trustworthiness directly affect investment outcomes.

non-U.S. institution financial

"Merrill Lynch International, a non-U.S. institution in accordance with section 240.13d-1"
