According to the UK's Office of Financial Sanctions Implementation, an entity is considered to be owned directly or indirectly if a person:

According to the UK's Office of Financial Sanctions Implementation (OFSI), an entity is considered owned or controlled by a designated person if one of several conditions is met. While ownership is often associated with shareholding (the threshold for which is more than 50%), the concept of control is equally important. One of the explicit tests for control is whether the person holds the right, directly or indirectly, to appoint or remove a majority of the board of directors of the entity. This right confers significant influence over the entity's strategic decisions and operations, thereby meeting the criteria for control under the UK sanctions regime.

A. The threshold for ownership based on shares or voting rights under the UK sanctions regime is more than 50%, not exactly 50%.
B. While a power of attorney grants authority, it is not one of the specific, standalone tests for ownership or control defined in the OFSI guidance.
D. The "more than 25%" threshold is associated with the UK's Persons with Significant Control (PSC) register, a different legal framework, not the OFSI's test for sanctions purposes.
