A subcontractor of the contractor may tender to the contractor acceptable substitute security as set forth in section 436.312 with a written request for release of retainage in the amount of the substitute security. The contractor shall tender the subcontractor’s substitute security to the owner with a like request, pursuant to the provisions of section 436.306. Provided that the subcontractor is not in default of its agreement with the contractor, the contractor shall pay over to the subcontractor, within five working days after receipt, any accumulated retainage paid by the owner to the contractor on account of substitute security tendered by the subcontractor, except that the contractor shall not be required to pay over retainage in excess of the amount properly attributable to work completed by the subcontractor at the time of payment. Provided that the subcontractor is not in default of its agreement with the contractor, the contractor shall refrain from withholding retainage from payments to the subcontractor to the extent the owner has refrained from withholding retainage from payments to the contractor on account of the subcontractor’s substituted security. The subcontractor shall be entitled to receive, upon receipt by the contractor, all income received by the contractor from the owner on account of income-producing securities deposited by the subcontractor as substitute security. Except as otherwise provided in this section, the contractor shall have no obligation to collect or pay to a subcontractor retainage on account of substitute security tendered by the subcontractor.
