Designation of Beneficiary(ies). Each Participant shall have the right to designate a beneficiary or beneficiaries (including contingent beneficiaries) to receive any benefits payable upon the death of a Participant. No such designation shall be effective unless completed and submitted in accordance with rules and procedures established by the Bank for this purpose. In the absence of an effective beneficiary designation, the Participant’s designated beneficiary shall be assumed to be the Participant’s surviving spouse or, if none, the Participant’s estate.
