Mo. Rev. Stat. § 382.280

Whenever it appears to the director that any person has committed a violation of sections 382.010 to 382.300 which so impairs the financial condition of a domestic insurer as to threaten insolvency or make the further transaction of business by it hazardous to its policyholders, creditors, shareholders or the public, then the director may proceed as provided by law to take possession of the property of such domestic insurer and to conduct the business thereof.
