Right to audit records. (a) Maintenance of books and records. Every contract and subcontract shall require the contractor or subcontractor, as applicable, to maintain books and records relating to the performance of the contract or subcontract and necessary to support amounts charged to the State under the contract or subcontract. The books and records shall be maintained by the contractor for a period of 3 years from the later of the date of final payment under the contract or completion of the contract and by the subcontractor for a period of 3 years from the later of the date of final payment under the subcontract or completion of the subcontract. However, the 3-year period shall be extended for the duration of any audit in progress at the time of that period's expiration. (b) Audit. Every contract and subcontract shall provide that all books and records required to be maintained under subsection (a) shall be available for review and audit by the Auditor General, chief procurement officer, internal auditor, and the purchasing agency. Every contract and subcontract shall require the contractor and subcontractor, as applicable, to cooperate fully with any audit. (c) Failure to maintain books and records. Failure to maintain the books and records required by this Section shall establish a presumption in favor of the State for the recovery of any funds paid by the State for which required books and records are not available.
