Liability Insurance

A commercial general liability insurance policy plays a crucial role by covering a wide range of liabilities which a company may be exposed to. The policy offers protection against claims which are related to bodily injury or property damage for which your company may be liable to pay. In short, the policy covers a wide range of liabilities which most of the organisations have to face during the course of its business.

A commercial general liability insurance policy includes an option to include extended reporting period, which covers those claims as well which are reported after the policy ceases to exist.

If you go with the extended reporting period endorsement option, your insurance policy will cover those claims as well which you have reported to the insurer during a particular time-period after your insurance policy has expired. In most cases, an extended reporting period is also known as the “tail” or “tail coverage.”

When might you need to add extended reporting period endorsement in your policy?

In general, a commercial general liability insurance policy covers for those claims which arise against you during the policy tenure. It doesn’t cover those claims which are filed after the policy has expired. Thus, there would be coverage gaps if your claims-made coverage is expired or not renewed. Such kind of issues can also arise if your claims-made policy coverage is replaced with an occurrence policy.

In case of a claims-made policy coverage, the triggering event is a claim which is filed against the policyholder during the policy tenure. Here, the injury could happen before or during the policy term, however, the claim should be filed when the policy is active. On the other hand, in case of occurrence policy, though, the policyholder can file claim after the policy has expired, the event must happen when the policy was active.

Different Types of extended reporting period endorsement

It is feasible to divide extended reporting period endorsement into two categories—one-way or two-way. A one-way tail is given if the insurer cancels or does not renewed the policy or rewrite your cover under an occurrence policy. Similarly, two-way tail is given if either you or your insurer cancel or does not renewed your policy.

Further, some commercial general liability insurance policies also offer more than one type of extended reporting period. Many insurers offer automatic short-term tail coverage if the insurer cancels or does not renew your policy.

Then there are some insurance policies which come with an option to buy broader coverage via an endorsement. This added coverage can also be called Supplemental (or Optional) ERP. Usually, an optional ERP is given only if the policyholder asks for the same in writing within a particular time frame (like 60 days) after the policy has expired. Remember, you would have to pay an additional premium to get this coverage.

It is essential to note that in most of the cases, the purchase of the extended reporting period endorsement doesn’t reinstate the limit because the limits which were available in the last policy tenure would be available during the policy extended period as well.


K.S Construction is in the business from last ten years. To safeguard itself from law suits that may arise in case of third-party bodily injuries and damages, the company bought a one-year claims-made commercial general liability insurance policy with an inception date of October 1, 2015. However, the insurer cancelled the policy on March 31, 2016, and replaced it with an occurrence policy coverage.

On May 1, 2016, the company received a notice of the claim for the bodily injuries which took place on November 5, 2015. As the claim was not made during the policy tenure, and the claims-made policy was expired, it was not covered by the insurer. Similarly, the new occurrence policy also not offered coverage because here the injury took place much before when the policy was in effect.

Here, the situation would have been different if K.S Construction had an insurance policy that covered extended reporting period endorsement as well. In case of claim, the insurer would have covered the previous claims as well which happened during the policy tenure but were filed when the policy was expired.
