Simple Interest Advances and Unreimbursed Servicer Advances. (a) If, as of the end of any Collection Period, one or more payments of Monthly P&I due under any Receivable (other than a Defaulted Receivable) outstanding at the end of such Collection Period shall not have been received by the Servicer and remitted to the Collection Account pursuant to Section 4.2, the Servicer may, at its option, make, on the Business Day preceding the Distribution Date immediately following such Collection Period, a Simple Interest Advance with respect to such Receivable by depositing in or crediting to the Collection Account the amount of Monthly P&I allocable to interest scheduled to have been paid during such Collection Period, assuming that such Receivable was paid on its due date, minus the amount of Monthly P&I actually received and allocated to interest, if any, with respect to such Receivable during such Collection Period.
(b) If the Servicer determines that it has made an Unreimbursed Servicer Advance, the Servicer shall reimburse itself for such Unreimbursed Servicer Advance from unrelated amounts received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)); provided, however, that the Servicer shall furnish to the Indenture Trustee and the Owner Trustee, on or before the Distribution Date following the Collection Period during which such reimbursement is taken, a certificate of a Servicing Officer setting forth the basis for such determination, the amount of such Unreimbursed Servicer Advance, the Receivable with respect to which such Unreimbursed Servicer Advance was made and the installments or other proceeds with respect to which such reimbursement was taken.
