Note to paragraph (d): The number of individuals that satisfy the definition of "beneficial owner," and therefore must be identified and verified pursuant to this section, may vary. Under paragraph (d)(1) of this section, depending on the factual circumstances, up to four individuals may need to be identified. Under paragraph (d)(2) of this section, only one individual must be identified. It is possible that in some circumstances the same person or persons might be identified pursuant to paragraphs (d)(1) and (2) of this section. A covered financial institution may also identify additional individuals as part of its customer due diligence if it deems appropriate on the basis of risk.
