2. The auditor, on his or her initiative and as often as he or she deems necessary, to the extent deemed practicable and consistent with the overall responsibility as contained in this chapter, shall make or cause to be made audits of all or any part of the activities of the state agencies.

In selecting audit areas and in evaluating current audit activity, the auditor may, at his or her discretion, consider and utilize, in whole or in part, the relevant audit coverage and applicable reports of the audit staffs of the various state agencies, independent contractors, and federal agencies.

5. The auditor shall be authorized to contract with federal audit agencies, or any governmental agency, on a cost-reimbursement basis, to perform audits of federal grant programs administered by the state departments and institutions in accordance with agreements negotiated between the auditor and the contracting federal audit agencies or any governmental agency. In instances where the grantee state agency shall subgrant such federal funds to local governments, regional councils of government, other local groups, or private or semiprivate institutions or agencies, the auditor shall have the authority to examine the books and records of these subgrantees to the extent necessary to determine eligibility and proper use in accordance with state and federal laws and regulations. The auditor shall charge and collect from the contracting federal audit agencies, or any governmental agencies, the actual cost of all the audits of the grants and programs that are conducted by the auditor under the contract. Amounts collected under these arrangements shall be deposited into the state treasury and be credited to the state auditor-federal fund and shall be available to hire sufficient personnel to perform these contracted audits and to pay for related travel, supplies, and other necessary expenses.

6. (1) In the auditor’s reports of audits conducted under this chapter and reports of special investigations, the auditor shall make any comments, suggestions, or recommendations deemed appropriate concerning any aspect of the auditee’s activities and operations.

(2) If, in making any report under subdivision (1) of this subsection, the auditor fails to make any suggestions or recommendations for any practice deemed inadequate by the auditor, the auditee may request that the auditor make, and the auditor shall provide, suggestions or recommendations, to the extent allowed under governmental auditing standards, for how to remedy the inadequate practice.

(3) The auditor shall make a summary of any report of an audit conducted under this chapter. Such summary shall contain a summary of the recommendations provided to the auditee, if any.

9. The auditor may, as often as the auditor deems necessary, conduct a detailed review of the bookkeeping and accounting systems in use in the various state agencies that are supported partially or entirely by state funds. Such examinations shall be for the purpose of evaluating the adequacy of systems in use by such agencies. In instances where the auditor determines that existing systems are outmoded, inefficient, or otherwise inadequate, the auditor shall recommend changes to the state agency and notify the general assembly of the recommended changes.

10. The auditor shall, through appropriate tests, determine the propriety of the data presented in the state comprehensive annual financial report, and shall express the auditor’s opinion in accordance with generally accepted government auditing standards.

12. At the conclusion of an audit, the auditor or the auditor’s designated representative shall supply a copy of a draft report of the audit to, and discuss such draft with, the official, or that official’s designated representative, whose office is subject to audit.

The auditor may charge a reasonable fee for providing a written copy of an audit report. The auditor also shall file a copy of the audit report in the auditor’s office; this copy shall be a permanent public record. Nothing in this subsection shall be construed to authorize or permit the publication of information that is otherwise prohibited by law from being disclosed.

15. Nothing in this chapter shall be construed by the courts of this state in a manner inconsistent with Article II of the Constitution of Missouri.

16. The auditor shall be responsible for receiving reports of allegations of improper governmental activities as provided in section 29.221. The auditor shall adopt policies and procedures necessary to provide for the investigation or referral of such allegations.

17. In accordance with the state’s records retention schedule, the auditor shall maintain a complete file of all audit reports and reports of other examinations, investigations, surveys, and reviews issued under the auditor’s authority. Audit workpapers and other evidence and related supportive material directly pertaining to the work of the auditor’s office shall be retained according to an agreement between the auditor and the state archives. To promote intergovernmental cooperation and avoid unnecessary duplication of audit effort, pertinent workpapers and other supportive material related to issued audit reports may be, at the discretion of the auditor and unless otherwise prohibited by law, made available for inspection by duly authorized representatives of the state and federal government who desire access to, and inspection of, such records in connection with a matter officially before them, including criminal investigations.
