ultimate beneficial owner (UBO)
(U.S.) The UBO of a U.S. affiliate is that person, proceeding up the affiliate’s ownership chain beginning with and including the foreign parent, that is not owned more than 50 percent by another person. The UBO consists of only the ultimate owner, other affiliated persons are excluded. If the foreign parent is not owned more than 50 percent by another person, the foreign parent and the UBO are the same. A UBO, unlike a foreign parent, may be a U.S. person.
