A name given to an insurance policy which covers against the loss caused by all perils except those which are specifically excluded by the terms of the policy. Frequently, a policy if insurance is written to insure damage to property caused by specific "named perils," which are listed on the policy. However, policies may be issued in certain cases to insure against "all risks of loss or damage" and are then called "all risks" policies. The term excludes insurance against certain hazards.
