The property and interests in property of such an entity, therefore, are blocked, and such an entity is a person whose property and interests in property are blocked pursuant to Sec. 547.201(a), regardless of whether the entity itself is listed in the Annex to Executive Order 13413 or designated pursuant to Sec. 547.201(a).
