If the full payment due is not received by the end of month in which it was due the servicer will advance the interest shortfall for receivables that are not in default. The servicer will be reimbursed for any interest advances from subsequent payments or collections relating to that receivable. At the time the servicer determines that advances will not be recoverable from payments on that receivable the servicer is entitled to recoup its advance from collections of other receivables.
