Zurich describes Coverage A as follow-form excess and Coverage B as lead umbrella; separately, its claims-made facility can offer up to $100 million through a joint Zurich, Chubb, and National Indemnity facility. Buyers should keep the shared facility distinct from the standard umbrella and identify participating insurers and terms in a proposal.

Berkshire Hathaway Specialty Insurance’s casualty overview lists pollution and contractor-form features. These address different risks rather than equivalent endorsements; a buyer should identify which specific exposure matters and request the applicable wording from each quoting market.
