Question 1

What is the defining feature of a reinsurance pool compared with an ordinary treaty?

Accepted Answer

Members share a defined book's combined premium and losses in fixed proportions, regardless of whose business produced them — A pool's members each take a fixed share of the whole pool's combined result, not just the results generated by their own underwriting.

Question 2

Why are pools commonly used for exposures like nuclear or terrorism risk?

Accepted Answer

Because the exposure is too large, correlated or systemic for normal competitive reinsurance to price efficiently alone — Pools exist where shared capacity, not competition, is the point — exposures so large or systemic that spreading them across many members is the only practical way to provide cover.
