What does the supplemental tail add to a claims-made CGL policy?

The supplemental tail feature of a claims-made Commercial General Liability (CGL) policy specifically extends the time during which claims can be reported after the policy has expired. This is crucial for scenarios where incidents leading to claims may not be immediately reported or discovered until after the policy terminates. By providing an additional period—often 60 days—following expiration, it allows insured parties to report claims for incidents that occurred while the policy was active, even though the policy itself is no longer in effect. This extension ensures that the policyholder has adequate protection against latent claims and potential liabilities that may surface after the policy's expiration date, thereby maintaining continuity of coverage and affording peace of mind.

In contrast to the other options, the supplemental tail does not cover injuries that occur after expiration, cancel existing claims, or increase the coverage limit of the policy. Each of those functions pertains to different aspects of insurance coverage or claims management, rather than the specific provision offered by the supplemental tail.
