Nationwide has submitted a group rate filing in California for its Workers’ Compensation program, effective February 1, 2026. The submission, led by Nationwide Assurance Company, includes Nationwide Mutual, Nationwide Insurance Company of America, Nationwide Property and Casualty, and Nationwide General.

The filing adopts the California Department of Insurance’s pure premium levels under Ruling #REG-2025-00007, applying a uniform class modification factor of 1.008. In total, 311 policyholders are affected across the five companies, with Nationwide Mutual representing the majority at 274 policies.

While the group’s overall indicated rate change is 0.0%, each entity shows a different requested rate impact—ranging from +3.7% to +10.6%, with Nationwide Mutual and Nationwide Assurance both seeking an 8% increase. The filing reflects approximately $6.8 million in written premium across all participating entities prior to the adjustment.

The update is purely rate-related, with no new rules or forms introduced, and aligns Nationwide’s Workers’ Compensation pricing with updated advisory loss costs while incorporating internal modification factors to reflect company-specific experience.
