Phase 5: Optimising the pool

Step 11: Adjust the Financial Structure
It is likely the user will have to run the tool multiple times to get the best structure for a given budget.
Guidance
Identify the biggest country risk liabilities on the Pool Analysis tab of the Risk Pool Structuring tool.
Return to Financial Structure Input tab and adjust up or down:
Attachment/Exhaustion points
Ceding Percentage
Reinstatements
Aggregate limit
Re-run the structure by pressing Run Model - every time the user makes adjustments they will need to run the model - and return to the country and pool analysis tabs to consider the new results, until:
The pool funding requirement is within budget
The coverage is maximised while staying within the risk appetite on solvency
The coverage needs requested from countries are balanced with affordability within the available funding
These decisions will need to be within the frame of the overall governance of the systems and should be fully transparent and accountable.
Step 12: Finalise and Communicate
Once the user has a workable design for the risk pool, they should document and clearly explain off-tool decisions, including:
Data sources, distribution fitting, and limitations
Why certain ceding percentages or triggers and structures were chosen
Funding availability, reinsurance decisions, and any residual risk
Utilise the graphs and tables in a structuring report
Transparency, fairness, and accountability are crucial. Communicate in accessible, culturally sensitive ways—especially around numerical probabilities and value judgments. Remember what the numbers are actually relating to in crisis and be mindful and respectful in how you communicate that in difficult decisions that often have to be made.
