Mont. Code Ann. § 33-2-1121

Whenever it appears to the commissioner that any person has committed a violation of this part 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 commissioner may proceed to take possession of the property of such domestic insurer and to conduct the business thereof.
