(1) No nonrenewals, cancellations, or revisions of ceded reinsurance agreements need be reported under RCW 48.43.200 if the nonrenewals, cancellations, or revisions are not material. For purposes of RCW 48.43.200 through 48.43.225, a material nonrenewal, cancellation, or revision is one that affects:

(a) More than fifty percent of a certified health plan's total reserve credit taken for business ceded, on an annualized basis, as indicated in the certified health plan's most recent annual statement;

(b) More than ten percent of a certified health plan's total cession when it is replaced by one or more unauthorized reinsurers; or

(c) Previously established collateral requirements, when they have been reduced or waived as respects one or more unauthorized reinsurers representing collectively more than ten percent of a total cession.

(2) However, a filing is not required if the certified health plan's total reserve credit taken for business ceded represents, on an annualized basis, less than ten percent of the statutory reserve requirement prior to any cession.
