(1) Each insurer required by WAC 284-07-100 through 284-07-230 to file an annual audited financial report must, within sixty days after becoming subject to the requirement, register with the commissioner in writing the name and address of the independent certified public accountant or accounting firm retained to conduct the annual audit set forth in WAC 284-07-100 through 284-07-230. Insurers not retaining an independent certified public accountant on the effective date of WAC 284-07-100 through 284-07-230 shall register the name and address of their retained independent certified public accountant not less than six months before the date when the first audited financial report is to be filed.

(2) The insurer shall obtain a letter from the accountant, and file a copy with the commissioner stating that the accountant is aware of the provisions of the Washington state insurance code, Title 48 RCW, and the rules and regulations that relate to accounting and financial matters and affirming that the accountant will express his or her opinion on the financial statements in terms of their conformity to the statutory accounting practices prescribed or otherwise permitted by the commissioner, specifying such exceptions as he or she may believe appropriate.

(3) If an accountant who was the accountant for the immediately preceding filed audited financial report is dismissed or resigns, the insurer shall, within five business days, notify the commissioner of this event. The insurer shall also furnish the commissioner with a separate letter within ten business days of the above notification stating whether in the twenty-four months preceding such event there were any disagreements with the former accountant on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure; which disagreements, if not resolved to the satisfaction of the former accountant, would have caused him or her to make reference to the subject matter of the disagreement in connection with his or her opinion. The disagreements required to be reported in response to this section include both those resolved to the former accountant's satisfaction and those not resolved to the former accountant's satisfaction. Disagreements contemplated by this section are those that occur at the decision-making level, i.e., between personnel of the insurer responsible for presentation of its financial statements and personnel of the accounting firm responsible for rendering its report. The insurer shall also in writing request the former accountant to furnish a letter addressed to the insurer stating whether the accountant agrees with the statements contained in the insurer's letter and, if not, stating the reasons for which he or she does not agree; and the insurer shall furnish such responsive letter from the former accountant to the commissioner together with its own.
