Common Shares of Beneficial Interest financial

"These shares are held by The RMR Group LLC ("RMR LLC")."

Common Shares of Beneficial Interest are units that represent ownership in a company or organization, like owning a piece of a pie. They give investors voting rights and a chance to share in profits, making them important for those looking to invest and have a say in how the organization is run.

beneficial owner financial

"Mr. Portnoy is also a beneficial owner and a director of RMR LLC and RMR Inc."

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.

indirect financial

"These shares are held by The RMR Group LLC ("RMR LLC")."

pecuniary interest financial

"they each disclaim such beneficial ownership except to the extent of their pecuniary interest therein."
