Claims Made Vs Occurrence

A Claims Made Liability Insurance Policy

A claims made insurance policy covers insurance claims filed during a given period of time. Generally speaking, a claim must be filed while a claims made policy is still in effect in order for it to be covered by the insurance carrier. This type of policy form is generally less expensive than an occurrence policy because there is no automatic coverage in place once the policy has ended. Businesses who typically purchase claims with the GL or professional liability insurance coverage include contractors, attorneys, and medical professionals. The most common types of policies written on a claims made basis include professional liability, directors and officers E&O, and employment practices liability insurance (EPLI).

Understanding the difference between a claims made form policy and an occurrence form policy for business liability insurance.

An important consideration with claims made polices is tail coverage. Tail coverage (also known as Extended Reporting Endorsement) is an additional policy most business owners will need to buy when they decide to retire or exit their business. Otherwise, a claim filed for work done in the past will not be covered under the claims made form. Unfortunately, their is no guarantee an insurance company will write a tail coverage policy and the premium may be expensive depending on prior policy claims.

The Occurrence Policy for Liability Insurance

An occurrence policy provides coverage for losses or claims that are related to a policy term. Therefore, a claim can be filed years later for a liability caused during a prior period of time as long as their was active coverage in place when the cause of the claim was created. While an occurrence policy form may be more expensive for some types of business, their is not future costs associated with buying tail coverage.

An occurrence policy is the more common from of coverage and a better choice for most business owners. It is more reasonable to have the coverage in place indefinitely for work performed than it is to gamble on find tail coverage or avoiding a future claim. In many instances, the additional cost of an occurrence policy form is minimal compared to purchasing a claims made policy.

Why Are There Two Types of Policies?

Claims made insurance coverage is more similar to early insurance programs when groups of businesses would form private insurance pools as means to cover potential losses. As insurance products and companies evolved into an industry, the idea of protecting risks based on a claims made basis followed. The primary reason claims made coverage is still around is because their is a demand for it and because insurance companies may only be willing to write certain types of risk on a claims made basis.

A claims made policy may be more affordable than an occurrence form insurance policy.

It is much easier for an insurance company to price insurance premium and measure profitability with claims made insurance forms because their is a clear start and stop date to coverage. With occurrence coverage, it can take decades for insurance companies to measure profit and loss because of the possibility of future insurance claims. In simple terms, a business owner who purchases an occurrence policy for one year will always be insured for any future claims that arise from word done by the insured during that one year term. With claims made coverage, the insured would need to buy additional tail coverage for that future exposure.

Disadvantages of Claims Made Insurance

Claims made polices are more complex than occurrence polices. They require a strong understanding of the policy language used in the insurance contract. Claims made coverage is triggered by a) the insured’s awareness of a potential claims and b) notification of the claim to the insurance company. Failing to properly notify the carrier can potentially void any coverage.

Four Claims Conditions Needed to Validate a Claims Made Policy:

    •  Insured must become aware of claim or potential claim during policy period
    •  Insured must report claim or potential claim to insurance carrier during policy period
    •  Claim cause must be within the claims made policy term or retroactive date
    •  Insured must attest and certify they had no prior knowledge of claim prior to purchasing policy

Retroactive date is typically the beginning date of the first annual claims made policy. Businesses that continue to renew their coverage will generally retain coverage back to the original date of coverage.

Contractors’ Claims Made Policies

Contractors and construction companies often find themselves with a claims made policy without fully realizing what their policy covers and how it works. The two most common reasons contractors buy claims made policies are a) they are often less expensive initially than occurrence polices, and b) they sometimes can’t get general liability quotes on an occurrence policy form.


Contractors are often sold claims made coverage without being informed of the risks and coverage differences.


The fact is that most liability claims against construction companies come long after the policy is terminated. Contractors with claims made coverage that don’t purchase tail coverage (and most do not) are putting their assets at risk once their policy terminates. Additionally, claims made insurance polices tend to get more and more expensive each year as the insurance company pick up more exposure for prior acts via the retroactive date. Finally, contractors who find themselves with a cancelled insurance policy may not be able to find another insurance company willing to offer coverage.

Contractors need to be aware of what type of general liability policy they have and what they are buying from agents. Our agency does not recommend claims made polices for most types of contractors unless they are fully aware of the risks associated with this type of coverage.
