(1) "Mandatory control level event" means any of the following events:

(a) The filing of an RBC report indicating that the insurer's total adjusted capital is less than its mandatory control level RBC;

(b) Notification by the commissioner to the insurer of an adjusted RBC report that indicates the event in (a) of this subsection, provided the insurer does not challenge the adjusted RBC report under RCW 48.05.460; or

(c) If, under RCW 48.05.460, the insurer challenges an adjusted RBC report that indicates the event in (a) of this subsection, notification by the commissioner to the insurer that the commissioner has, after a hearing, rejected the insurer's challenge.

(2) In the event of a mandatory control level event:

(a) With respect to a life and disability insurer, the commissioner shall take those actions necessary to place the insurer under regulatory control under chapter 48.31 RCW. In that event, the mandatory control level event is sufficient grounds for the commissioner to take action under chapter 48.31 RCW, and the commissioner has the rights, powers, and duties with respect to the insurer as are set forth in chapter 48.31 RCW. If the commissioner takes actions pursuant to an adjusted RBC report, the insurer is entitled to the protections of RCW 48.31.121 pertaining to summary proceedings. However, the commissioner may forego action for up to ninety days after the mandatory control level event if the commissioner finds there is a reasonable expectation that the mandatory control level event may be eliminated within the ninety-day period.

(b) With respect to a property and casualty insurer, the commissioner shall take those actions necessary to place the insurer under regulatory control under chapter 48.31 RCW, or, in the case of an insurer that is writing no business and that is running off its existing business, may allow the insurer to continue its runoff under the supervision of the commissioner. In either event, the mandatory control level event is sufficient grounds for the commissioner to take action under chapter 48.31 RCW and the commissioner has the rights, powers, and duties with respect to the insurer as are set forth in chapter 48.31 RCW. If the commissioner takes actions pursuant to an adjusted RBC report, the insurer is entitled to the protections of RCW 48.31.121 pertaining to summary proceedings. However, the commissioner may forego action for up to ninety days after the mandatory control level event if the commissioner finds there is a reasonable expectation that the mandatory control level event may be eliminated within the ninety-day period.
