Each audit report shall include only financial information, findings, and conclusions that are adequately supported by evidence in the auditor's working papers to demonstrate or prove, when called upon, the basis for the matters reported and their correctness and reasonableness. In connection with this, each municipality shall retain the right of inspection of the auditor's working papers and shall make them available to the Comptroller, or his or her designee, upon request. The audit report shall consist of the professional opinion of the auditor or auditors with respect to the financial statements or, if an opinion cannot be expressed, a declaration that the auditor is unable to express such opinion and an explanation of the reasons he or she cannot do so. Municipal authorities shall not impose limitations on the scope of the audit to the extent that the effect of such limitations will result in the qualification of the opinion of the auditor or auditors. Each audit report filed with the Comptroller shall be accompanied by a copy of each official statement or other offering of materials prepared in connection with the issuance of indebtedness of the municipality since the filing of the last audit report.

(b) For fiscal year 2019 and each fiscal year thereafter, the audit report shall include the financial statements for governmental activities, business-type activities, discretely presented component units, and each major fund and aggregated nonmajor fund. The audit report shall also include the professional opinion or opinions of the auditor or auditors with respect to the financial statements or, if an opinion cannot be expressed, a declaration that the auditor is unable to express an opinion and an explanation of the reasons he or she cannot do so. Each auditor's report shall include a representation by the auditor or auditors conducting the audit has been performed in accordance with generally accepted auditing standards. Municipal authorities shall not impose limitations on the scope of the audit to the extent that the effect of the limitations will result in the modification of the opinion or opinions of the auditor or auditors. Each audit report filed with the Comptroller shall be accompanied by a copy of each official statement or other offering of materials prepared in connection with the issuance of indebtedness of the municipality since the filing of the last audit report.

(c) For fiscal year 2019 and each fiscal year thereafter, audit reports shall contain financial statements prepared in accordance with generally accepted accounting principles and audited in accordance with generally accepted auditing standards if the last audit report filed preceding fiscal year 2019 expressed an unmodified or modified opinion by the auditor that the financial statements were prepared in accordance with generally accepted accounting principles.

(d) For fiscal year 2019 and each fiscal year thereafter, audit reports containing financial statements prepared in accordance with an other comprehensive basis of accounting may follow the best practices and guidelines outlined by the American Institute of Certified Public Accountants and shall be audited in accordance with generally accepted auditing standards. If the corporate authority of a municipality submits an audit report containing financial statements prepared in accordance with generally accepted accounting principles, thereafter all future audit reports shall also contain financial statements prepared in accordance with generally accepted accounting principles.

(e) Audits may be made on financial statements prepared using either an accrual or cash basis of accounting, depending upon the system followed by the municipality, and audit reports shall comply with this Section.
