In accordance with the Office of Foreign Assets Control 50% Rule, which entities would be...

Under the OFAC 50% Rule, an entity must be treated as a Specially Designated National (SDN) — even if not named on the SDN List — when:

One SDN owns 50% or more of the entity, OR

Multiple SDNs collectively own 50% or more of the entity (ownership must be aggregated).

Applying this rule:

A: 98% ownership by a single SDN → Blocked (exceeds 50%).

B: 35% + 15% = 50% aggregate ownership by two SDNs → Blocked (meets 50%).

C: 20% + 25% = 45%, which does not meet the threshold → Not blocked.

D: 12% + 18% + 28% = 58% aggregate ownership by SDNs → Blocked (exceeds 50%).

E: 45% + 3% = 48%, which is below 50% → Not blocked.

F: 10 SDNs × 4% = 40%, which is below 50% → Not blocked.

Thus, only A, B, and D meet or exceed the 50% aggregate ownership requirement defined by OFAC.
