At some point or another we have all purchased an insurance policy. For most of us, our primary experience with insurance is dealing with auto, home, or health insurance. These types of insurance policies are called occurrence policies.


Occurrence-based policies are the most common types of policies and are appropriate for most types of insurance. For professional liability insurance however, claims made policies are the status quo. 

 

As an account executive at Protexure Insurance Agency, I have heard from many lawyers who have questions about how professional liability insurance operates. Oftentimes, their questions boil down to one common theme, a misunderstanding of the difference between claims made and occurrence policies. 

 

In an effort to clarify, below I compare claims made and occurrence policies to demonstrate why professional liability insurance is written on a claims made basis.  And, what you need to know about the two to better understand how professional liability insurance operates.

 

What is a claims-made policy?

 

A claims-made policy refers to an insurance policy that provides coverage based on when a claim is made against it, rather than when the claim event occurred. While the event must have occurred during the policy period, the coverage that responds is the coverage that is in place when the claim is made, not when the event occured. 

 

For example, let's say you’ve maintained insurance coverage for 10 years. After 8 years you decided to increase your policy limits. Unfortunately in year 10, a client sues and you must file a claim to your insurance carrier. The event that occurred happened in year 7 of your insurance coverage. With a claims made policy, the claim is covered with the policy and limits you have currently in year 10 not the policy and limits that you had in year 7 when the event occured. 

 

A claims-made policy is a popular option for when there is a delay between when events occur and when claimants file claims. 

 

However, the policy only covers claims made while the policy is active. In other words, the insured must maintain continuous coverage in order to cover the claim. 

 

What is an occurrence policy?

 

An occurrence policy covers claims made for incidents sustained during the life of the insurance policy, even if the claim is filed after the policy has been canceled. It is designed to protect you against long-tail events – incidents that could cause damage years after they occur. The policy that will respond to the claim is the policy that was in place when the event occurred. 

 

To illustraight how occurrence policies work, let's take another look at the example we shared previously. You have maintained insurance coverage for 10 years, in year 8 you decide to increase your limits. In year 10 a claim is filed for an event that occurred in year 7. 

 

Under an occurrence policy, you will be covered with the insurance policy you had during year 7. Even though you have since increased your coverage, you will not get to experience those benefits because the event occurred before the changes were made. 

 

Policy Form

 

Claims-Made

The policy form for a claims made insurance policy is very similar to that of an occurrence policy. The main difference is the request for prior insurance coverage information.

 

With a claims made policy, a claim that is made against you is covered by the policy in place at the time the claim is made. Claims made policies require the insured to maintain continuous coverage, therefore, the insurer needs to know how long you have maintained coverage.  

 

A policy form is filled out every year, regardless of whether you are switching carriers or not. While your current carrier may already know how long you have maintained coverage, if you are switching carriers, informing the new carrier of the date you began your coverage is very important. This date will tell the insurance carrier how many years of work they are covering. 

 

The date you began your coverage is known as a prior acts date, it is established the day the very first claims-made policy is issued. This date will remain the same throughout your years of coverage as long as you maintain continuous coverage. 

 

All subsequent renewal policy forms will use the same initial prior acts date. You are covered for claims that occur after this date. Claims occurring before the original prior acts date are not covered.

 

Occurrence

When you have an occurrence form, an incident that occurs during the policy period will be covered by that policy, regardless of how many years later the claim is reported. 

 

Therefore, unlike claims made policies, the occurrence policy form will not request information about prior coverage.

 

Incidents that occur before the occurrence form policy is issued are not covered. You do not need to renew the insurance policy to maintain coverage for the year you were insured.

 

Prior Acts 

 

Claims Made

As mentioned in the section above, a prior acts date is an important part of claims made policies. 

 

Coverage for prior acts is an insurance policy feature that covers claims made on insurable events that occurred prior to the current policy period but after the prior acts date. 

 

Your prior acts date (also known as retroactive date) is the start date of the first claims-made policy you are actively renewing, also known as the inception date of your first policy. 

 

You are insured for any covered incident as long as it occurs on or after your prior acts date. 

 

That date remains the same and is not advanced as long as you renew your policy. For example, if you have a prior acts date of 2015 on your policy and it is now 2020, your policy covers you for the last five years. 

 

Your prior acts date is also transferable between insurance companies. If you are currently insured for professional liability, you can bring that coverage with you to a new insurance carrier and they  will endorse your new policy with your prior acts date. 

 

For example, let's say you are insured with ABC Insurance Company with a claims-made policy and you purchased your first professional liability insurance police with them in 2015. That means you have a prior acts date of 2015. In 2020, you decide to switch to a new carrier, 123 Insurance Company, and ask for prior acts coverage. 123 Insurance Company would issue you a new policy that includes coverage back to 2015. Your policy would be identical to someone who bought a policy with 123 Insurance Company  in 2015 and was actively renewing.

 

Occurrence

Occurrence policies do not provide coverage for prior acts. With an occurrence policy, coverage remains available for claims that arise years after they have expired. But, the coverage available is the coverage you purchased at that time, not your current policy coverage.

 

Additionally, if an accident or event occurs during the term of an occurrence policy, that policy must respond to any future claim. For example, if you are insured with ABC Insurance Company from 2010-2015 and then you switch carriers in 2015, any claims arising from 2010-2015 would be covered by ABC Insurance Company and not the new carrier.

 

Step Rating 

 

Claims Made

Another characteristic unique to claims made policies is the process of step rating.

 

With a claims made policy, both the incident and the claim have to be filed during the coverage period, therefore the claims-made insurer has little risk of loss the first year a new policy is in force. In fact, they have reduced risk the first few years of coverage because the likelihood of an error occurring and a claim being filed all within a year or two, is very low. 

 

Because of this, the first few years of premium for claims-made coverage is lower. Each year the policy continuously renews, the coverage period expands, and the insurance company’s exposure to loss increases.  

 

For the first five years of an in-force claims-made policy, the premiums increase incrementally to reflect this increased risk. 

 

Usually by the sixth year of claims-made coverage, the risk of loss levels off and the policy reaches maturity. Mature claims-made rates are typically very close to rates for occurrence coverage.

 

Occurrence

Occurrence policies do not use step-rating to determine premiums. With an occurrence policy, the likelihood that the insurance carrier will experience a loss is consistent every year. Therefore, the premiums paid for occurrence policies are typically comparable to a mature claims-made policy.

 

Extended Reporting Period 

 

Claims-Made

If you no longer need a professional liability insurance policy, whether the result of retirement or a career change, an extended reporting period is a must for claims made policies. In order to retain protection for the years insured under the claims-made policy after canceling a policy, the insured must purchase an extended reporting period (also known as tail coverage).

 

Tail coverage extends the time alleged incidents may be reported on a claims-made policy.  A tail offers coverage for incidents that happen while the claims-made policy is effective, but are reported after the policy has expired.  

 

Depending on the insurance company, if you meet certain requirements, tail coverage may be offered for free upon retirement.  If the requirements have not been met, the claims-made policy may come with the option to purchase tail coverage for a specified period, such as 1, 3, or 5 years, or an unlimited amount of time. If you elect not to have tail coverage, you would not be covered for claims reported after the policy is terminated.

 

Occurrence

For occurrence policies, there is no need to purchase an extended reporting period or tail coverage because incidents that happened during the policy regardless of when the claim is reported to the carrier are covered.

 

Pricing 

 

Claims-Made

Claims-made policies are initially significantly less expensive than occurrence policies. As covered in the step rate section, typically for the first five years of coverage, claims-made policies are discounted and tend to be less expensive than occurrence policies.  However, this price begins to level out as times goes on and your business faces more exposures. Eventually, the cost of claims made policies become comparable to occurrence policies.

 

One cost difference with a claims-made policy is the need to buy tail coverage when the policy is terminated. Fortunately, many claims-made policies offer free tail coverage for death, disability or permanent retirement, a feature that can result in considerable cost savings if you qualify.

 

Occurrence

For occurrence coverage, rates are based upon an insurance company's projections of claim costs in future years and all premiums for each policy period are known up-front at the time the policy is purchased. There are no additional costs incurred.

 

Why Professional Liability Policies are Claims Made

 

One thing you may have noticed while in the process of purchasing professional liability insurance is occurrence policies are not always readily available.  Many carriers that once offered them have discontinued offering professional liability occurrence policies.

 

The majority of all legal malpractice insurance policies written today provide claims-made coverage. This pivot to claims made policies is one that is mutually beneficial to the insurance carrier and the insured.

 

One of the benefits of professional liability insurance being a claims-made policy is the cost savings. Claims made policies are often less expensive than occurrence policies. 

 

Claims made carriers can typically predict the frequency and severity of claims that will be reported during the policy period. By doing so, they are able to more accurately assess what should be charged for a policy. Oftentimes this results in lower premiums for insureds. 

 

Additionally, claims made policies are step-rated which also results in additional cost savings during the first few years of claims made coverage. 

 

A major benefit of a claims-made policy is that changes to your current coverage or changes to the policy limits applies to all your prior years of coverage. As time goes on, you have the ability to better protect yourself against possible claims. You are not bound by past coverage decisions and have the ability to continuously improve your coverage. 

 

Along those same lines, with a claims-made policy you can move coverage from one carrier to another. If you find a better policy from another carrier, you have the ability to protect your past under the new policy and carrier. This is increasingly beneficial if the new carrier offers you a better policy for a lower price.

 

Professional liability insurance policies for lawyers are typically written on a claims made basis. While you might be able to find a policy or two written on an occurrence basis, it may not be the most beneficial to your firm. 

 

While neither an occurrence policy or a claims made policy is inherently “better,” these policies do adhere to various insurance lines better than others. As a business owner, you will most likely handle many different types of insurance. Understanding the differences between the two types of policies will help you better understand how to protect your business.
