JACKSON, Miss. — House members are advancing a bill to strip a tax subsidy and authority from Mississippi’s insurer of last resort for hurricane-prone coastal residents.

House Bill 948 would divert $11 million a year in subsidies from the Mississippi Windstorm Underwriting Association to help buy rural firetrucks and firefighting equipment through 2021.

Gulf Coast House members oppose the bill.

It’s being pushed by Insurance Commissioner Mike Chaney, who says the association, called the “wind pool,” spends too much on backup insurance. The bill requires Chaney’s approval before the pool can buy above a certain amount of backup coverage, known as reinsurance.

Chaney says the measure will make premium increases less likely for the pool’s 25,000 coastal policyholders. They pay $1,700 on average to cover wind and hail, buying other insurance elsewhere.
