No disbursement shall be made under subsection (c) to any person until the total amount paid by or for the account of the obligor from sources other than the proceeds of the obligation equals at least 25 percent or 12.5 percent, whichever is applicable under
section 53709(b) of this title, of the aggregate actual cost of the vessel, as previously approved by the Secretary or Administrator. If the aggregate actual cost of the vessel has increased since the Secretary’s or Administrator’s initial approval or if it increases after the first disbursement is permitted under this subsection, then no further disbursements shall be made under subsection (c) until the total amount paid by or for the account of the obligor from sources other than the proceeds of the obligation equals at least 25 percent or 12.5 percent, as applicable, of the increase, as determined by the Secretary or Administrator, in the aggregate actual cost of the vessel. This paragraph does not require the Secretary or Administrator to consent to finance any increase in actual cost unless the Secretary or Administrator determines that such an increase in the obligation meets all the terms and conditions of this chapter or other applicable law.
