[1]Contributing to the negative IBNR reserves for some accident years is a lag in the timing of expected reinsurance recoveries under the Navigators ADC with NICO. Recoveries from NICO will not be collected until the Company has cumulative loss payments for all covered lines of more than the attachment point.
