Mont. Code Ann. § 80-2-209

Because of the unusual or unexpected variation in the severity of damage to crops that occurs from year to year and in order to enable the hail insurance board to spread the effect of these variations more evenly over all years, the board may negotiate for and secure reinsurance of a part of the risk in any year when the need for reinsurance appears advisable to the board. The board may use money from hail insurance fees for the purchase of reinsurance whenever it appears to the board that reinsurance is necessary and advisable.
