Granite State Insurance Co. v. Star Mine Services, Inc., No. 21-5852 (6th Cir. 2022)
Annotate this Case
Star, a mine staffing company, bought workers’ compensation insurance from Granite. Early in each policy year, Star gave Granite an estimate of its total payroll, which Granite used to calculate an estimated premium. Star paid the preliminary installment. After each year, Granite audited Star’s records to produce an exact payroll number, then charged additional premiums or made reconciliation payments. A 2018 audit revealed that Star had significantly underestimated its 2017 payroll, as it had for 2016. To avoid a similar situation with the 2018 policy, Granite adjusted its estimated premium for Star halfway through the year. In accordance with industry guidelines, Granite increased Star’s 2018 estimated premium to reflect 2017’s actual payroll numbers, giving Star four weeks to pay the difference. Star never paid. Granite canceled the policy three months early. Star closed its business. To determine Star’s final premium—and whether it owed a reconciliation payment—Granite needed to complete its year-end audit. Star would not comply. Granite’s final bill, including the updated estimated premium, prorated for early cancellation, was $1,485,323, including an “audit noncompliance charge” (double 2018’s total estimated premium).
Granite sued for breach of contract. The Sixth Circuit affirmed summary judgment for Granite, rejecting Star’s argument that the noncompliance charge is an unenforceable penalty. Kentucky’s insurance regulator approved the rates that Kentucky insurance companies charge, barring their review.
