Hiscox submitted updates to its ISO Commercial General Liability (CGL) program in Connecticut, revising both loss costs and state-specific multipliers as part of a broader rate adjustment.

The filing reflects a 12.5% overall rate increase, below the 15.9% indicated change, and applies to a book of approximately 5,361 policyholders representing $4 million in written premium.

The update replaces prior loss cost exception pages and adjusts class-level pricing across multiple territories, impacting both premises/operations and products/completed operations exposures.

While the overall change is moderate, variability at the class level is significant, with maximum increases reaching as high as 361.8%, indicating targeted repricing rather than a uniform adjustment.

The changes follow a prior revision in June 2025 and are scheduled to take effect June 15, 2026 for new business and October 13, 2026 for renewals, under a file-and-use framework.
