Yes, an extended reporting period endorsement is informally referred to as tail coverage. Under certain circumstances, this feature can be useful because claims-made lawyers professional liability policies cover only claims that are made and reported during the policy period. This means that regardless of when the act or omission giving rise to the claim occurred, if the claim is not reported during the legal malpractice insurance policy period or a brief specified period (usually 30 or 60 days) after expiration, then that claim is not covered. Therefore most insurers offer optional extended reporting period endorsements for specified periods of time. For example, an attorney might purchase a 24-month ERP or a 36-month ERP. It should be noted that these ERPs do not extend the attorneys professional liability policy period, change the scope of coverage provided or increase the insurer’s limits of liability. ERPs only extend the time available for reporting the claim.
