What is tail coverage / extended reporting period?

Tail coverage, known formally as an extended reporting period (ERP), is a critical feature of claims-made insurance policies. When a claims-made policy ends, whether due to cancellation, non-renewal, retirement, or switching carriers, you lose the ability to report new claims under that policy. Tail coverage extends the reporting window so that claims arising from acts committed during the policy period can still be reported after the policy has terminated.

Most malpractice policies include a short automatic extended reporting period, typically 30 to 60 days, at no additional cost. This basic ERP gives you a brief window to report claims that were imminent at the time of policy expiration. However, malpractice claims often surface years after the underlying legal work was performed, making the automatic ERP inadequate for most situations.

A supplemental or optional extended reporting period can be purchased to extend the reporting window for one to five years, or in some cases indefinitely. The cost of tail coverage is typically calculated as a percentage of the final year's premium. A one-year tail might cost 75 to 100 percent of the annual premium, while a three-year tail can run 150 to 200 percent. An unlimited tail, which provides indefinite reporting rights, may cost 200 to 300 percent of the final annual premium.

Tail coverage becomes essential in several scenarios. Retiring attorneys need tail coverage because malpractice claims can emerge years after the last matter was handled. Attorneys leaving a firm to join another firm or go in-house should confirm whether their departing firm's policy provides tail coverage for their prior work. When switching carriers, tail coverage from the old carrier can fill gaps if the new carrier does not offer a matching prior acts date.

Some policies include favorable tail provisions, such as automatic free tail coverage upon retirement after a specified number of continuous years with the carrier, or upon death or permanent disability. These provisions can represent significant value and should be a factor in your carrier selection. Always review the tail coverage options and pricing before binding a new policy, as they become relevant at the moment you least expect them.
