A credit union is required to maintain a bond for protection and indemnity of members, in reasonable amounts against dishonesty, fraud, defalcation, forgery, theft, embezzlement, and other similar insurable losses with an insurance or surety company authorized to do business in this state. Coverage against such losses shall include all agents who do not otherwise provide protection and indemnity for the credit union, directors, officers, and employees of the credit union acting independently or in collusion or combination with any person or persons whether or not they draw salary or compensation.
