4 terms

general partner financial

"Intelligent Fanatics Capital Management LLC (IFCM) is the general partner of IFCM MicroCap Fund 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.

beneficial owner financial

"may be deemed to be the beneficial owner of, the shares beneficially owned by the Fund"

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.

shared voting and investment power financial

"Mr. Cassel has shared voting and investment power with respect to the shares"

limited and general partnership interest financial

"other than the shares attributable to his limited and general partnership interest therein"
