Excess Casualty Underwriter

You spend most days reading large-account submissions, modeling exposure against attachment points, and negotiating with brokers on excess layer terms. The book runs against the carrier's appetite for large-loss tail risk and the broader excess market dynamics. Quote-to-bind cycles can be deliberate — these aren't small policies.

What surprises people new to excess casualty is how much rests on a few catastrophic events that may never happen — the book runs profitably for years, then a single tower-shaking loss tests the underwriting. Variance across employers is wide: at major casualty carriers excess underwriting is structured with senior authority; at specialty E&S markets you carry broader individual responsibility.

Underwriters who thrive tend to enjoy modeling rare events and negotiating with senior brokers. CPCU, ARM, and excess-specific credentials anchor advancement. The trade-off is the long-tail accountability — excess layers carry exposure for years, and reserving questions surface late.
