Voluntary Reinsurance Receivables by Financial Strength Rating
CNA has established an allowance for doubtful accounts on voluntary reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. The following table summarizes the outstanding amount of voluntary reinsurance receivables, gross of any collateral arrangements, by financial strength rating:

(a)Expected credit losses for legacy A&EP receivables are ceded to NICO and the reinsurance limit on the LPT has not been exhausted, therefore no allowance is recorded for these receivables and they are excluded from the table above. See Note 8 for more information on the LPT. Also excluded are receivables from involuntary pools.
