Any licensee that is unable to obtain day care insurance with liability limits of at least one hundred thousand dollars per occurrence from the voluntary insurance market or from any market assistance plan organized pursuant to section 906, chapter 305, Laws of 1986, is eligible to apply for coverage through the association. The association's service insurer shall promptly process such application and, if the licensee is judged to be an acceptable insurable risk, offer coverage to the licensee. In view of the purpose of chapter 141, Laws of 1986, every licensee will be presumed to be an acceptable insurable risk for the association. To refuse coverage to any licensee meeting the other eligibility requirements of this section, the association must have the prior written approval of the commissioner. The commissioner will grant such approval only if the association demonstrates that extraordinary circumstances justify refusing coverage to such individual licensee.
