An administrator shall have and keep in full force and effect a fidelity bond equal to at least 10 percent of the amount of the funds handled or managed annually by the administrator. However, the office may not require a bond greater than $500,000 unless the office, after due notice to all interested parties and opportunity for hearing and after consideration of the record, requires an amount in excess of $500,000 but not more than 10 percent of the amount of the funds handled or managed annually by the administrator.
