4 terms

indirectly beneficially owned financial

"The reported securities may be deemed to be indirectly beneficially owned by MPGP"

general partner financial

"indirectly beneficially owned by MPGP, as the general partner of MPF"

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.

investment manager financial

"indirectly beneficially owned by MCM, as the investment manager of MPF"

pecuniary interest financial

"disclaims beneficial ownership of the securities reported herein except to the extent of his or its pecuniary interest"
