|(a) Because contracts awarded under this Chapter are reimbursement-only contracts, a contractor must submit financial status reports and invoices, as directed by the OAG. (b) A contractor must ensure that its final invoice is received no later than the 45th calendar day after the end of the contract period (liquidation date). If this date falls on a weekend or a holiday, then the OAG will honor receipt on the following business day. On the liquidation date, if contract funds are on hold for any reason, the funds will lapse and cannot be recovered by the contractor. (c) Invoices received after the above deadline may not be paid by the OAG. (d) If necessary, the OAG may allow an extension beyond the established deadline.
