(a) The insured shall have the right to designate the beneficiary or beneficiaries of insurance maturing on or after August 1, 1946, and shall, subject to regulations, at all times have the right to change the beneficiary or beneficiaries of such insurance without the consent of such beneficiary or beneficiaries.

(b) Insurance maturing on or after August 1, 1946, shall be payable in accordance with the following optional modes of settlement:

(1) In one sum.

(2) In equal monthly installments of from thirty-six to two hundred and forty in number, in multiples of twelve.

(3) In equal monthly installments for one hundred and twenty months certain with such payments continuing during the remaining lifetime of the first beneficiary.

(4) As a refund life income in monthly installments payable for such period certain as may be required in order that the sum of the installments certain, including a last installment of such reduced amount as may be necessary, shall equal the face value of the contract, less any indebtedness, with such payments continuing throughout the lifetime of the first beneficiary; however, such optional settlement shall not be available in any case in which such settlement would result in payments of installments over a shorter period than one hundred and twenty months.

(c) Except as provided in the second and third sentences of this subsection, unless the insured elects some other mode of settlement, such insurance shall be payable to the designated beneficiary or beneficiaries in thirty-six equal monthly installments. The first beneficiary may elect to receive payment under any option which provides for payment over a longer period of time than the option elected by the insured, or if no option has been elected by the insured, in excess of thirty-six months. In the case of insurance maturing after September 30, 1981, and for which no option has been elected by the insured, the first beneficiary may elect to receive payment in one sum. If the option selected requires payment to any one beneficiary of monthly installments of less than $10, the amount payable to such beneficiary shall be paid in such maximum number of monthly installments as are a multiple of twelve as will provide a monthly installment of not less than $10. If the present value of the amount payable at the time any person initially becomes entitled to payment thereof is not sufficient to pay at least twelve monthly installments of not less than $10 each, such amount shall be payable in one sum. Options (3) and (4) shall not be available if any firm, corporation, legal entity (including the estate of the insured), or trustee is beneficiary.

(d) If the beneficiary of such insurance is entitled to a lump-sum settlement but elects some other mode of settlement and dies before receiving all the benefits due and payable under such mode of settlement, the present value of the remaining unpaid amount shall be payable to the estate of the beneficiary. If no beneficiary is designated by the insured, or if the designated beneficiary does not survive the insured, or if a designated beneficiary not entitled to a lump-sum settlement survives the insured, and dies before receiving all the benefits due and payable, then the commuted value of the remaining unpaid insurance (whether accrued or not) shall be paid in one sum to the estate of the insured. In no event shall there be any payment to the estate of the insured or of the beneficiary of any sums unless it is shown that any sums paid will not escheat.

(e) Under such regulations as the Secretary may promulgate, the cash surrender value of any policy of insurance or the proceeds of an endowment contract which matures by reason of completion of the endowment period may be paid to the insured under option (2) or (4) of this section. All settlements under option (4), however, shall be calculated on the basis of The Annuity Table for 1949. If the option selected requires payment of monthly installments of less than $10, the amount payable shall be paid in such maximum number of monthly installments as are a multiple of twelve as will provide a monthly installment of not less than $10.

(f)

(1) Following the death of the insured and in a case not covered by subsection (d)—

(A) if the first beneficiary otherwise entitled to payment of the insurance does not make a claim for such payment within two years after the death of the insured, payment may be made to another beneficiary designated by the insured, in the order of precedence as designated by the insured, as if the first beneficiary had predeceased the insured; and

(B) if, within four years after the death of the insured, no claim has been filed by a person designated by the insured as a beneficiary and the Secretary has not received any notice in writing that any such claim will be made, payment may (notwithstanding any other provision of law) be made to such person as may in the judgment of the Secretary be equitably entitled thereto.

(2) Payment of insurance under paragraph (1) shall be a bar to recovery by any other person.
