A gift of specific securities, rather than their equivalent value, entitles the beneficiary only to:
(1) As much of the gifted securities of the same issuer held by the trust estate at the time of the occurrence of the event entitling the beneficiary to distribution.
(2) Any additional or other securities of the same issuer held by the trust estate because of action initiated by the issuer, excluding any acquired by exercise of purchase options.
(3) Securities of another issuer held by the trust estate as a result of a merger, consolidation, reorganization, or other similar action initiated by the original issuer.
