What Does Negative Ibnr Mean

IBNR can be negative for any number of reasons, the most significant probably being when claims settle for less than their case estimates. Other reasons could include salvage, subrogation, recoveries from other third parties (such as other insurers for example), etc.

How do you explain IBNR?

Incurred but not reported (IBNR) is a type of reserve account used in the insurance industry as the provision for claims and/or events that have transpired, but have not yet been reported to an insurance company.

Why does IBNR increase?

Therefore, the amount of IBNR for a given accident year generally decreases over time. The declines for all prior years are often more than compensated for by the IBNR needed for the new accident period, and thus overall IBNR increases.
