Extended Reporting Period
A provision in claims-made policies allowing the insured to report claims after the policy expires for acts occurring during the coverage period.
What It Is
An Extended Reporting Period (ERP) is a provision in claims-made policies that allows the insured to report claims after the policy has expired, for acts or omissions that occurred during the policy period or after the retroactive date. ERPs come in two forms: basic and supplemental.
The basic ERP is typically included in the policy at no additional cost and provides a short reporting window (usually 60 days) after the policy expires. This basic ERP is automatic and provides limited time to report claims that were in process or recently discovered at the time of policy expiration.
The supplemental ERP (commonly called 'tail coverage') is an optional purchase that extends the reporting period for a longer duration—typically 1, 3, 5 years, or unlimited. The supplemental ERP must be purchased within a specified window after policy termination and requires an additional premium. It provides substantially more protection than the basic ERP and is recommended whenever a claims-made policy is terminated without replacement coverage.
Why It Matters for Brokers
Understanding the ERP is critical for brokers managing claims-made policies. The basic ERP provides minimal protection—60 days is not enough time for most professional errors to be discovered and claimed. The supplemental ERP (tail) is essential when coverage is being terminated. Brokers who fail to advise about the ERP and tail option expose both their clients and themselves to significant liability.
Real-World Example
An IT consulting firm merges with a larger company on March 1. Their $2M E&O policy with a retroactive date of 2017 expires at merger. The basic ERP provides 60 days (until May 1) to report claims. In August—after the basic ERP expires—a client from 2021 discovers a data migration error causing $450,000 in damages and sues. With no active policy, no tail, and the basic ERP expired, the claim is uninsured. A 3-year supplemental ERP (cost: $14,000) would have allowed the claim to be reported and covered.
Common Mistakes
- 1Relying on the basic 60-day ERP as sufficient protection after policy termination—60 days is far too short for most professional errors to surface.
- 2Missing the deadline to purchase the supplemental ERP, which is typically 30-60 days after policy termination and cannot be extended.
- 3Not budgeting for ERP costs in business transition planning (mergers, acquisitions, retirement, firm dissolution).
