Section 2309.13 - Definition, Availability and Maintenance of Independent Certified Public Accountants Workpapers

(a) Workpapers are the records kept by the independent certified public accountant of the procedures followed, the tests performed, the information obtained, and the conclusions reached pertinent to the accountant's audit of the financial statements of an insurer. Workpapers, accordingly, may include audit planning documentation, work programs, analyses, memoranda, letters of confirmation and representation, abstracts of company documents and schedules or commentaries prepared or obtained by the independent certified public accountant in the course of the independent certified public accountant's audit of the financial statements of an insurer and which support the accountant's opinion.

(b) Every insurer required to file an audited financial report pursuant to these regulations, shall require the accountant to make available for review by insurance department examiners, all workpapers prepared in the conduct of the accountant's audit and any communications related to the audit between the accountant and the insurer, at the offices of the insurer, at the insurance department or at any other reasonable place designated by the commissioner. The insurer shall require that the accountant retain the audit workpapers and communications until the insurance department has filed a report on examination covering the period of the audit but no longer than seven (7) years from the date of the audit report.

(c) In the conduct of the aforementioned periodic review by the insurance department examiners, it shall be agreed that photocopies of pertinent audit workpapers may be made and retained by the department. Such reviews by the department examiners shall be considered examinations, and all working papers and communications obtained during the course of such examinations shall be afforded the same confidentiality as other examination workpapers generated by the department.
