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

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

(b) Notification by the commissioner to the carrier of an adjusted RBC report that indicates the event in (a) of this subsection, provided the carrier does not challenge the adjusted RBC report under RCW 48.43.330; or

(c) If, under RCW 48.43.330, the carrier challenges an adjusted RBC report that indicates the event in (a) of this subsection, notification by the commissioner to the carrier that the commissioner has, after a hearing, rejected the carrier's challenge.

(2) In the event of a mandatory control level event, with respect to a carrier, the commissioner shall take those actions necessary to place the carrier 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 shall have the rights, powers, and duties with respect to the carrier as are set forth in chapter 48.31 RCW. If the commissioner takes actions pursuant to an adjusted RBC report, the carrier 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.
