Coverage description

An Insurance Services Office (ISO) standard form. It covers bodily injury and property damage caused by a cyber incident, and loss of electronic data resulting from physical injury to tangible property, under the umbrella, subject to separate loss of electronic data, each cyber incident occurrence and aggregate limits.

How the form has changed

The 06 26 edition is restructured to work with the cyber incident and access or disclosure exclusions in the umbrella coverage part, setting those exclusions aside for Coverage A instead of repeating its own exclusions and definitions. The coverage it grants is the same.

Editions

Edition dates as filed, newest first. Filing counts include every state submission that lists the edition.
