Class A Common Stock financial

"security title is listed as Class A Common Stock"

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.

weighted average price financial

"The price reported in Column 4 is a weighted average price"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

indirect financial

"transactions are reported with indirect ownership by trust"

trust financial

"The shares are held in a trust for the benefit of Tiffany Horne Noonan"

A trust is a legal setup in which one party (the trustee) holds and manages assets—like cash, stocks or property—on behalf of other people (beneficiaries) according to instructions from the person who created it (the grantor). Think of it as a locked box with a keyholder who must follow written rules; for investors it matters because trusts influence who controls and benefits from assets, affect taxes and succession, and can change how quickly or transparently shares are bought, sold or voted.

open market or private transaction financial
