(1) For the purpose of this section, the following definitions shall apply:

(a) "Insurer" shall have the same meaning as set forth in RCW 48.01.050. It also includes health care service contractors registered under chapter 48.44 RCW, health maintenance organizations registered under chapter 48.46 RCW, fraternal benefit societies registered under chapter 48.36A RCW, and self-funded multiple employer welfare arrangements authorized under chapter 48.125 RCW.

(2) Each authorized insurer must file with the National Association of Insurance Commissioners (NAIC) an annual statement for the previous calendar year in the general form and context as adopted by the NAIC for the kinds of insurance to be reported upon. The filing with the NAIC will be deemed to be a filing with the commissioner. To effectuate RCW 48.05.250, 48.05.400, 48.36A.260, 48.44.095 and 48.46.080 and to enhance consistency in the accounting treatment accorded various kinds of insurance transactions, the valuation of assets, and related matters, insurers must adhere to the appropriate Annual Statement Instructions and the Accounting Practices and Procedures Manuals adopted by the NAIC.

(3) This section does not relieve an insurer from its obligation to comply with specific requirements of Titles 48 RCW and 284 WAC.

(4) Annual statements:

(a) Annual statements for all domestic insurers must be filed electronically with the NAIC. The filing with the NAIC will be deemed to be a filing with the commissioner. The commissioner has the discretion to allow an insurer to file electronically with the commissioner. The insurer must demonstrate that filing with the NAIC will create an undue financial hardship for the insurer. Applications for permission to not file with the NAIC must be received by the commissioner at least ninety days before the annual statement is due. If the NAIC does not collect or accept any annual statement supplement, schedule, form, or other document, then the domestic insurer must file the supplement, schedule, form, or other document electronically with the commissioner.

(b) To comply with statutory requirements that annual statements must be verified by the oaths of at least two of the insurer's officers, insurers may:

(i) Use a method of electronic signature verification that has been approved by the commissioner for use by the insurer; or

(ii) Include in the electronic filing an image of the original signatures in PDF format as noted on the commissioner's website. This electronically filed document must contain a legally binding signature of the company officers and the notary administering the oath.

(c) Both the electronic annual statement and the verification of that statement by the oaths of two officers must be received by the NAIC and the commissioner, if applicable, to complete an annual statement filing. The date of receipt of the later of the electronic annual statement or verification is considered the receipt date of the annual statement.

(5)(a) Each domestic insurer must file quarterly statements of its financial condition with the NAIC. The filing with the NAIC will be deemed to be a filing with the commissioner. The commissioner has the discretion to allow an insurer to file electronically with the commissioner. The insurer must demonstrate that filing with the NAIC will create an undue financial hardship for the insurer. Applications for permission to not file with the NAIC must be received by the commissioner at least ninety days before the quarterly statement is due. If the NAIC does not collect or accept any quarterly statement supplement, schedule, form, or other document, then the domestic insurer must file the supplement, schedule, form, or other document electronically with the commissioner. Each foreign insurer must file quarterly statements of its financial condition with the NAIC. The statements must be filed with the NAIC or the commissioner, if applicable, not later than the forty-fifth day or the fifteenth day of the second month after the end of the insurer's calendar quarters, whichever is later. The quarterly statements must be in the form and content as adopted by the NAIC for quarterly reporting by insurers, must be prepared according to appropriate Annual and Quarterly Statement Instructions and the Accounting Practices and Procedures Manuals adopted by the NAIC and must be supplemented with additional information required by this title and by the commissioner. Quarterly statements for the fourth quarter are not required.

(b) Quarterly statements must be filed with the NAIC by electronically transmitting the quarterly statement as described in this subsection.

(c) To comply with statutory requirements that quarterly statements must be verified by the oaths of at least two of the insurer's officers, insurers may:

(i) Use a method of electronic signature verification that has been approved by the commissioner for use by the insurer; or

(ii) Include in the electronic filing an image of the original signatures in PDF format as noted on the commissioner's website. This electronically filed document must contain a legally binding signature of the company officers and the notary administering the oath.

(6) As a part of any investigation by the commissioner, the commissioner may require an insurer to file monthly financial statements whenever, in the commissioner's discretion, there is a need to more closely monitor the financial activities of the insurer. Monthly financial statements must be filed in the commissioner's office no later than the twenty-fifth day of the month following the month for which the financial statement is being filed. Insurers must electronically transmit the monthly financial statements, as described in this subsection, in PDF or other format as noted on the commissioner's website. The monthly financial statements must be the internal financial statements of the company. In addition, the commissioner may require these internal financial statements to be accompanied by a schedule converting the financial statements to reflect financial position according to statutory accounting practices and submitted in a form using the same format and designation as the quarterly financial statements of insurers. "Financial statements" as used in this subsection includes:

(a) Statement of assets;

(b) Liabilities, capital and surplus;

(c) Statements of revenue and expenses; and

(d) Statements of cash flows.

(7) Health care service contractors shall use the Health Statement Form adopted by the NAIC for their statutory filings.

(8) Each health care service contractor's, health maintenance organization's, and self-funded multiple employer welfare arrangement's annual statement must be accompanied by an additional data statement form (IC-13A-HC/IC-14-HMO).

(9) The commissioner may allow a reasonable extension of the time for filing the financial statements. A request for an extension must be in writing. The request must be received prior to the due date of the filing and must state good cause for the extension. An extension can only be granted in writing; paper, fax, or email is considered "writing" for purposes of this subsection.
