Each audit report shall include the certification of the auditor or auditors making the audit that the audit has been performed in compliance with generally accepted auditing standards. 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 county since the filing of the last audit report.
    (b) For fiscal year 2019 and each fiscal year thereafter, the audit report shall contain statements that set forth the financial position and the results of financial operations for financial statements for governmental activities, business-type activities, discretely presented component units, and each major fund and aggregated nonmajor funds for each fund, account, and office of the county government. The audit report shall include the professional opinion or opinions of an auditor or auditors with respect to the financial status and 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.

    (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 conformity 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 presented 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.
