Incurred But Not Reported

Claims that have occurred but have not yet been reported to the insurance company, abbreviated as IBNR. Insurance companies must estimate and set aside reserves for these unknown future claims to ensure they can pay all obligations, even though the specific incidents haven't been reported yet.

Example

“The auto insurance company increased its IBNR reserves after the holiday weekend, anticipating that many accident claims from the heavy traffic period would be reported in the following weeks.”

Memory Tip

Think 'Hidden Icebergs' - like icebergs mostly hidden underwater, IBNR represents the hidden claims beneath the surface that insurers know exist but can't see yet.

Why It Matters

IBNR reserves directly impact insurance companies' financial stability and your premiums, as insurers must maintain adequate funds to pay these future claims. Understanding this concept helps consumers recognize why insurance companies need substantial reserves and why claims can sometimes take time to process as companies manage both known and unknown obligations.

Common Misconception

Many people assume that if they don't immediately report a claim, they forfeit their right to coverage, but IBNR exists precisely because valid claims can emerge days, weeks, or even years after an incident. However, policyholders shouldn't delay reporting unnecessarily, as policies typically require 'prompt' or 'timely' notification, and late reporting could complicate the claims process.

In Practice

After a major hailstorm damaged 10,000 homes in a city, ABC Insurance received 3,000 claims in the first week. Based on historical data, they estimated that 70% of affected policyholders typically report within the first month. Therefore, they established IBNR reserves for approximately 4,300 additional claims (7,000 unreported claims anticipated) totaling $43 million, even though these specific claims hadn't yet been filed.

Etymology

The term emerged from actuarial accounting practices, combining 'incurred' from Latin 'incurrere' meaning 'to run into' or happen, with the concept of unreported claims that exist but remain unknown to insurers.
