If benefits to an individual are computed on benefit wage credits earned from more than one employer, at least one of whom is a reimbursing employer, the amount payable to the compensation fund by each reimbursing employer is the amount that bears the same ratio to the total benefits paid to the individual as the total base period benefit wage credits for the individual from that employer bears to the total base period benefit wage credits for the individual from all employers.
