IBNR

Represents the liability for unpaid claims not reflected in the case reserve estimates for individual losses. The two components to IBNR reserves are pure IBNR and broad or bulk IBNR; pure IBNR are those claims that have occurred but have not yet been reported as of the evaluation date; and, broad or bulk IBNR is the additional development on known claims or the increase in reserve value as the claim are investigated and settled.
