Jewelers Mutual filed updates to its Businessowners (BOP) program in New Jersey, introducing revised base loss costs with a modest impact on premiums.

The filing, submitted on April 14, 2026, applies to commercial policyholders and is scheduled to take effect on November 1, 2026, for both new and renewal business.

Overall, the change results in a 0.65% increase across the book, affecting 204 policyholders and approximately $1.27 million in written premium, with a projected premium increase of about $8,300.

The update is driven by adjustments to base loss costs, informed by historical loss experience, expense trends, catastrophe modeling, and reinsurance costs. The company also referenced the latest ISO loss cost filings as part of its methodology.

While the indicated rate change was higher at 2.43%, the selected impact reflects a more conservative adjustment, keeping changes limited at the policy level.
