Tail Coverage
An extended reporting period endorsement purchased when a claims-made policy is cancelled, allowing claims from prior acts to be reported after expiration.
What It Is
Tail coverage, formally known as an Extended Reporting Period (ERP) endorsement, is purchased when a claims-made policy is cancelled, non-renewed, or not replaced. It extends the period during which claims can be reported to the expiring policy, even though the policy is no longer active. The tail does not extend the coverage period for new acts—it only allows reporting of claims arising from acts that occurred during the policy period (or after the retroactive date).
Tail coverage is typically available as a basic ERP (usually 60 days at no cost, included in the policy) or a supplemental ERP (1 year, 3 years, 5 years, or unlimited, purchased for an additional premium). The unlimited tail is the most comprehensive and most expensive option, typically costing 150-250% of the expiring annual premium.
Tail coverage is a one-time purchase at the time of policy cancellation or non-renewal. It cannot be purchased later—the option expires, typically within 30-60 days of the policy's termination. Missing the window to purchase tail coverage can leave years of professional activity permanently uninsured.
Why It Matters for Brokers
Tail coverage is essential whenever a claims-made policy is terminated without replacement coverage that maintains the same retroactive date. Common situations requiring tail coverage include: retirement or dissolution of a professional practice, merger or acquisition where the acquiring entity's policy does not provide prior acts coverage, and any lapse in claims-made coverage. Brokers must advise clients about tail coverage well before policy termination.
Real-World Example
A physician retiring from a surgical practice has maintained claims-made malpractice insurance since 2008. Upon retirement, the doctor cancels the policy. The carrier offers a tail (supplemental ERP) for $95,000 (200% of the $47,500 annual premium) providing an unlimited reporting period. The doctor declines to save money. Three years later, a patient sues over a surgical error from 2022. With no active policy and no tail, the doctor has no coverage and faces a $1.8M malpractice claim with personal assets at risk. The $95,000 tail would have provided coverage.
Common Mistakes
- 1Not advising clients about the tail coverage option before they cancel a claims-made policy—the purchase window is limited and cannot be reopened.
- 2Recommending against tail coverage to save money without explaining the ongoing exposure from prior acts that could generate claims for years.
- 3Not factoring tail coverage costs into merger and acquisition planning—the cost of tail coverage should be negotiated as part of the deal.
