Risk to decision
How the deal comes together.
Problem
A regional insurer wants to keep its $20M indemnity cat tower but add fast parametric capacity on top — and see the combined economics in one view, not three separate spreadsheets.
Structure
A $20M property-cat XoL layered with a $10M parametric wind top-up and a $5M parametric quake aggregate — $35M total limit, with attachment, exhaustion, and reinstatement terms.
Evidence
Standalone the three layers sum to $2.72M expected loss; modeled jointly the program is $2.31M — a 15% diversification benefit shown explicitly across the parametric and indemnity sections.
Decision
A single program view at a 7.6% blended rate on line for ART and captive discussions. Illustrative only.
