Cause of Loss Forms

There are property forms that define the cause of loss, or perils, for which coverage is provided.  Basic and Broad forms are also referred to as Named Peril forms because they provide coverage only for the specific causes listed in the policy as being covered.  The Special form is also referred to as Open Peril or All Risks form because it provides coverage for loss from any causes except those that are specifically excluded.

Basic (Good) – provides coverage for the following named perils: fire, lightning, explosion, smoke, windstorm, hail, riot, civil commotion, aircraft, vehicles, vandalism, sprinkler leakage, sinkhole collapse, and volcanic action.

Broad (Better)- provides named perils coverage for the perils insured against in the basic causes of loss form (fire, lightning, explosion, smoke, windstorm, hail, riot, civil commotion, aircraft, vehicles, vandalism, sprinkler leakage, sinkhole collapse, volcanic action), plus the following additional perils: falling objects; weight of snow, ice, or sleet; water damage (in the form of leakage from appliances); and collapse from specified causes.

Special (Best)- provides what is referred to as all risks coverage: coverage for loss from any cause except those that are specifically excluded.
