(1) No nonrenewals, cancellations, or revisions of ceded reinsurance agreements need be reported under RCW 48.44.530 if the nonrenewals, cancellations, or revisions are not material. For purposes of RCW 48.44.530 through 48.44.555, a material nonrenewal, cancellation, or revision is one that affects:

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

(b) More than ten percent of a health care service contractor’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 a health care service contractor’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.
