Arch submitted a workers’ compensation group captive rating plan in Connecticut, effective May 2, 2026.

The plan defines how individual members are rated, with a minimum eligibility threshold of $75,000 in countrywide estimated premium, targeting mid-market employers. It is structured to reward strong risk management through a fixed expense framework and performance-based pricing.

Individual member premiums may deviate by up to ±50% from standard rates, creating meaningful pricing differentiation for well-performing risks. The filing also references actuarial support from firms such as Pinnacle and Milliman for loss projections.

The structure positions Arch to scale a captive-based approach to workers’ compensation, offering competitive pricing for better risks while drawing them away from the traditional market.
