A grantee must properly obligate and expend funds to satisfy all outstanding liabilities no later than 45 days after the end of the grant period. The OAG will not make any reimbursements to a grantee unless the final request for funds is postmarked by the 45th day after the end of the grant period. If the 45th day falls on a weekend or federal holiday, the OAG will honor receipt or a postmark on the next business day. All payments made after the completion of the grant period must relate to obligations encumbered prior to the end of the grant period.
