If an annuity for one person is in pay status on the valuation date, and if the payment of a death benefit after the valuation date to another person, who need not be identifiable on the valuation date, depends in whole or in part on the death of the pay status annuitant, then the plan administrator shall value the death benefit using—

(2) The mortality rates under paragraph (c) of this section to represent the mortality of the death beneficiary.
