The commission shall participate in an arrangement for the payment of benefits determined by combining an individual's wages and employment covered under this subtitle and the wages and employment covered under the unemployment compensation laws of another state or the United States, or both, if the arrangement is approved by the United States secretary of labor in consultation with the state unemployment compensation agencies as reasonably calculated to ensure the prompt and full payment of benefits. The arrangement must provide for:
(1) applying the base period of one unemployment compensation law to a claim that combines an individual's wages and employment covered under two or more unemployment compensation laws; and
(2) avoiding the duplicate use of wages and employment because of the combination.
