When an agent’s client needs coverage that the agent's own insurer cannot provide, what is the additional coverage called?

The additional coverage needed when an agent's client requires protection that their own insurer cannot provide is referred to as excess insurance. This type of insurance comes into play when an underlying policy has reached its limit, and the client still seeks additional coverage.

Excess insurance acts as a layer on top of existing policies and is designed to provide further financial protection in the event of significant claims or losses that exceed the amounts covered by the primary policy. This is particularly important in scenarios where substantial risks are present or when high-value assets require more comprehensive coverage.

In this context, the other terms do not accurately fit the scenario. Supplemental insurance typically refers to additional policies that provide benefits on top of a primary health or life insurance plan, rather than addressing gaps in coverage. Alternative coverage might suggest different forms of insurance but does not specifically convey the idea of providing extra amounts beyond existing limits of coverage. Correlative coverage is not a widely recognized term in the insurance industry and does not pertain directly to the additional insurer options for clients needing more protection. Thus, excess insurance is the most fitting term for the additional coverage required in these cases.
