Key Terms

beneficial owner, investment advisor, general partner, pecuniary interest

4 terms

beneficial owner regulatory

"may be deemed the beneficial owner of the Class A Common Shares owned by Dark Mirage, LP"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

investment advisor financial

"MILFAM LLC is the investment advisor of Dark Mirage, LP"

An investment advisor is a person or firm that provides personalized guidance on buying, selling and managing investments and often oversees client portfolios for a fee. For investors this matters because the advisor shapes risk, costs and long-term returns, and is typically required by law to act in the client’s best interests — think of them as a financial coach or GPS that helps navigate choices and avoid costly detours.

general partner financial

"MILFAM GP, LLC is the general partner of Dark Mirage, LP"

A general partner is the person or firm that runs an investment partnership and legally represents it — they make the day-to-day decisions, choose which assets to buy or sell, and are responsible for the partnership’s obligations. Investors care because the general partner’s judgment, risk-taking and fee and profit-sharing arrangements determine both the potential returns and the level of exposure to losses; think of the GP as the ship’s captain whose skill and honesty shape the voyage’s outcome.

pecuniary interest regulatory

"other than to the extent he or it may have a pecuniary interest therein"
