(2) Filings of commercial liability insurance rates for markets specified by the Director of the Department of Consumer and Business Services shall be submitted by an insurer or rating organization to the director for review prior to the effective date if the average annual rate level increase or decrease for each market exceeds 15 percent. Factors to be considered by the director in specifying a market to be subject to this section may include:
(a) The nature and extent of competition;
(b) The size and significance of the coverage provided;
(c) Reinsurance availability;
(d) The volume of cancellations and nonrenewals; and
(e) Changing conditions in the economic, judicial and social environment.
(3) Except as otherwise provided in ORS 737.209, the effective date of a commercial liability insurance filing required by subsection (2) of this section to be submitted to the director for review shall be the date specified therein but not earlier than the 30th day after the filing is received by the director. After review of the filing, the director may authorize an earlier effective date, if appropriate. The 30-day waiting period may be extended to 60 days if the director gives written notice within such waiting period to the insurer or rating organization which made the filing that the extended period is needed for consideration of the filing. A filing subject to subsection (2) of this section that has not been approved or disapproved within the waiting period, or any extension thereof, shall be deemed approved.
(4) Supporting actuarial data shall accompany every filing of commercial liability insurance rates. The data shall be in sufficient detail to justify the rate level change and shall demonstrate compliance with ORS 737.310 governing the making of rates. [1987 c.774 §48]
