Cumulative Liability

Definition

Reinsurance:

Cumulative liability in the context of reinsurance refers to the total of the limits of liability of all reinsurance policies that a reinsurer has outstanding on a single risk. This includes all contracts from all insurers representing all lines of coverage related to that risk.

Liability Insurance:

In liability insurance, cumulative liability is the total of the limits of liability of all policies that an insurer has outstanding on a single risk. This can involve various policies such as personal automobile policies (PAP) and personal umbrella liability policies, among others.

Examples

Reinsurance Example:
- A reinsurer, XYZ Re, covers multiple insurance companies for a commercial property in earthquake-prone regions. The property is main office building. XYZ Re’s cumulative liability would be the total of all the reinsurance agreements from different insurers covering that specific building against earthquake damage.
Liability Insurance Example:
- An individual has a personal automobile policy (PAP) with a liability limit of $1 million and a personal umbrella liability policy with an additional $2 million limit. The cumulative liability for this individual would be $3 million for any single automobile accident.

Frequently Asked Questions

What constitutes cumulative liability in reinsurance?

Cumulative liability in reinsurance includes all the limits of liability from various reinsurance contracts that a reinsurer holds on a single risk. This encompasses the entire spectrum of policies protecting different aspects of that risk.
