Key Terms

Beneficial ownership, Sole dispositive power, Schedule 13G, Investment adviser (IA)

4 terms

Beneficial ownership regulatory

"Amount beneficially owned: 23,101,316 (b) Percent of class: 8.89%"

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.

Sole dispositive power regulatory

"Sole power to dispose or to direct the disposition of: 22,690,164"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

Schedule 13G regulatory

"Item 1. (a) Name of issuer: Galiano Gold Inc."

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.

Investment adviser (IA) regulatory

"Donald Smith & Co., Inc. IA"

An investment adviser (IA) is a person or firm that provides personalized guidance on buying, selling, or holding investments and often manages client portfolios for a fee. Investors should care because an IA has a legal duty to act in the client's best interest—think of them as a navigator who plans and steers your financial journey—so their advice, fee structure and potential conflicts can directly affect returns and financial risk.
