Actuarial case explained
How much available capital covers an aggregate risk requirement?
Purpose
Decision informed
Interpret coverage and diversification without presenting a heuristic as a current CNSF calculation.
Benefits and cash flows
- 1Life, P&C, and investment modules.
- 2Aggregation with pedagogical correlations.
- 3Available capital compared with total RCS.
Assumptions
| Assumption | Value / unit | Source and status |
|---|---|---|
| RCS factors | Fixed percentages and stepped bands | Illustrative Pedagogical heuristics, not CNSF |
| Correlations | Fixed matrix | Illustrative Laboratory assumption |
| Coverage | Capital / RCS | Convention Canonical package definition |
Method
Quadratic aggregation
The matrix recognizes dependence across modules; coverage is calculated after aggregation.
RCS = √(rᵀ · ρ · r)Results and interpretation
A ratio above 1 covers this scenario's requirement; it does not certify regulatory solvency.
Applied example
Capital and solvency
The Solvency Capital Requirement (RCS) is the capital the CNSF requires an insurer to hold for an adverse year. This example examines aggregation across life, P&C, and investment modules through a simplified scenario whose scope is documented as an educational reference.
Adjust the parameters to observe how the result changes.

Actuarial interpretation
Solvency is assessed by comparing available capital against the requirement. Aggregation with correlations recognizes that life, P&C, and investment risks do not materialize simultaneously, so the total RCS is lower than the sum of the modules.
Validation and limits
What is checked
- —The capital/RCS ratio is tested by scale, by boundary, and by insufficiency.
- —Identity: under the matrix used, the aggregate never exceeds the sum of the modules.
What it does not prove
- —Factors do not implement the complete CNSF stochastic model.
- —SAT paths carry rates and citations that are still unverified, which is why they are shown as indeterminate.
