Excess Policy – A Type of Insurance Coverage That Provides Extra Protection in High-Cost Claims

In plain language: An excess policy is a form of insurance that kicks in when the costs of a claim exceed the limits of your primary policy. Think of it as a safety net that catches large claims your main policy can’t fully cover. 

Technical definition: An excess policy (also referred to as excess liability coverage or excess liability insurance) provides coverage above the limits of an underlying policy. It only activates once the underlying policy’s limits are exhausted. This type of coverage can be associated with various lines of business, such as auto insurance, homeowners insurance, or business insurance, and is commonly seen in the policy endorsements or in its own standalone policy form. 

Imagine a catastrophic loss event like a fire in a warehouse—an event that exceeds the liability limits of the business’s primary insurance policy. This is where an excess policy steps in to cover the rest. 

TL;DR

  • An excess policy provides extra coverage when the costs exceed the limits of a primary policy. 
  • It’s vital in mitigating high-stakes risks in day-to-day agency work. 
  • A common misunderstanding is that this policy has its own coverage, it doesn’t; it sits upon your underlying coverage. 
  • A best practice is to regularly review policies to ensure adequate coverage, accounting for the potential of catastrophic losses. 

What Is an Excess Policy in Insurance?

An excess policy provides coverage in case of severity losses that exceed the limits of the underlying policy. This kind of policy doesn’t have its own underlying coverage; instead, it relies on the primary insurance for initial claims payment, after which it then steps in when the primary policy’s limit is reached. 

They are commonly associated with liability insurance where potential claims can significantly exceed primary coverage limits. This could be tied to various lines of business such as general liability, auto liability, employers liability, etc.  

An important distinction is that excess policies may follow the terms of underlying policies or might have terms of their own, known as “stand-alone excess policies”.

Common Questions About Excess Policy

What’s the difference between primary coverage and excess coverage? 

Primary coverage is your main insurance policy that covers initial claims, while excess coverage provides insurance beyond the limits of primary policies. 

Why would a client need an excess policy? 

If a client has high-value assets or high liability risks, an excess policy provides additional financial protection beyond their primary insurance policy limits. 

What is the relationship between an underlying policy and an excess policy? 

The underlying policy is the first line of financial defense in a claim—once its limit is exhausted, the excess policy starts to take over the remaining costs. 

How does an excess policy work with multiple underlying policies? 

If multiple underlying policies are in place, the excess policy follows the hierarchy of underlying policies, stepping in only when the limits of these policies are exhausted.

Real Claim Examples Involving Excess Policy

Scenario 1: A business faced a large claim when a fire occurred in their premises, causing significant damages. Their primary commercial insurance reached its limit, and their excess policy was required to cover the remaining high-cost repairs, ultimately saving the company from great financial hardship.  

Scenario 2: In a car accident involving serious personal injury claims, the insured’s primary auto insurance policy reached its liability limit. The excess policy, in this case, took over and covered the additional medical costs that went beyond the primary policy coverage.

Scenario 3: A homeowner faced a complex liability claim due to an accident on the property, resulting in costly medical bills and lawsuit expenses. The primary homeowners insurance capacity was exhausted, and the excess liability policy stepped in, protecting the homeowner from significant financial loss. 

Limitations and Common Mistakes

  • Confusing excess policy with primary policy: Excess coverage only kicks in when the primary insurance capacity is exhausted. 
  • Assuming an excess policy can provide primary coverage: It doesn’t, it is dependent on an underlying policy. 
  • Not understanding what the excess policy covers: It is crucial to understand whether the policy follows form or is a stand-alone excess. 
  • Forgetting to ensure underlying policies are kept in force: If the underlying coverage lapses, the excess policy may not provide the coverage. 

How to Explain Excess Policy to Clients

Personal Lines client “Think of an excess policy as a backup for your main insurance. If something happened—like a severe car accident—and your auto insurance doesn’t cover all the costs, your excess policy would cover the rest.” 

Small Business owner “Your liability insurance has coverage limits. If, for example, someone suffered a severe injury at your premises and the claim exceeds your policy limit, that’s where an excess policy comes into play. It picks up where your regular insurance stops, protecting your business from catastrophic financial loss.” 

CFO or Risk Manager “Given our risk exposure, an excess liability policy can be an important aspect of our risk management strategy. It covers us beyond our primary insurance, ensuring our organization’s financial stability in the event of severe, high-cost claims.”
