044-34 Wyo. Code R. § 1
The previous approval of any expense reimbursement or stated benefit cancer policy shall not be continued past July 1, 1980, unless on or prior thereto proper and adequate certification is submitted to the Department of Insurance for each policy approved showing that the benefits in relation to premium charged have or will produce a minimum sixty (60) percent loss ratio over a five year period of time. Such certifications shall be submitted annually thereafter. If the certification shows in any year for which it has been filed that any previously approved cancer policy has produced or will produce less than a sixty (60) percent loss ratio over a five year period of time, such policy may be withdrawn from use and refilled within thirty days from the time the certification was submitted to reflect necessary premium adjustments or changes in policy benefits.
