§ 404.1910. Person qualifies under more than one totalization agreement.
(a) An agreement may not provide for combining periods of coverage under more than two social security systems.
(b) If a person qualifies under more than one agreement, the person will receive benefits from the U.S. only under the agreement affording the most favorable treatment.
(c) In the absence of evidence to the contrary, the agreement that affords the most favorable treatment for purposes of paragraph (b) of this section will be determined as follows:
(1) If benefit amounts are the same under all such agreements, benefits will be paid only under the agreement which affords the earliest month of entitlement.
(2) If benefit amounts and the month of entitlement are the same under all such agreements, benefits will be paid only under the agreement under which all information necessary to pay such benefits is first available.
(3) If benefit amounts under all such agreements are not the same, benefits will be paid only under the agreement under which the highest benefit is payable. However, benefits may be paid under an agreement under which a lower benefit is payable for months prior to the month of first entitlement to such higher benefit.
