Working with actuarial teams at insurance carriers

A mid-size property and casualty carrier operating Commercial Auto, General Liability, and Workers Compensation lines. Their actuarial team of four was rebuilding IBNR models quarterly in Excel, with a separate workbook per line. After onboarding, HyperCal consolidated all three lines into a single model run, eliminating cross-workbook formula dependencies and generating the audit log automatically. The first regulator-ready export was produced on the same day as the model run, rather than the following week.

A smaller specialty carrier covering Marine and Professional Liability. Their single in-house actuary was spending approximately 60 percent of the close cycle on model maintenance rather than analysis. After deploying HyperCal, the maintenance work was eliminated. The actuary now runs the quarterly close without external support, with time reallocated to rate adequacy review and regulatory correspondence.

A health insurance carrier subject to quarterly reserve reporting to the Financial Supervisory Service. Their prior process generated documentation manually after the model run, sometimes inconsistently with the parameters actually used. HyperCal's automatic audit trail resolved this by capturing parameters at the point of use. The Q1 2026 reserve package was accepted by the carrier's appointed auditors on first submission without additional clarification requests.
