The client faced issues with their insurance model after upgrading a library and required independent validation and profitability analysis.

Solytics conducted regression testing with the new library and developed an independent Excel model to:

1. Compare the client's model output with the replicated model.

2. Identify differences and their causes.

3. Review the model at a granular level, suggest remedial actions, and provide a final comprehensive report summarizing all observations and recommendations.

- Identified flawed aspects of the model components and provided a remediation plan.

- Proposed updates to out-of-date tables and streamlined models to facilitate automatic library updates.

- Implemented necessary changes in methods and assumptions affecting reserving.
