Coverage description

An Insurance Services Office (ISO) standard form. It amends the exclusion for earthquakes that begin before the policy starts, so loss from earthquake or volcanic eruption on or after inception is covered if the series began within 72 hours before inception.

How the form has changed

The 02 19 edition updates the earthquake endorsements it applies to and the form date. The coverage wording is the same as 08 99.
