(8)The longer an exposure has been non-performing, the lower the probability for the recovery of its value. Therefore, the portion of the exposure that should be covered by provisions, other adjustments or deductions should increase with time, following a pre-defined calendar. NPEs purchased by an institution should therefore be subject to a calendar that starts to run from the date on which the NPE was originally classified as non-performing, and not from the date of its purchase. For that purpose, the seller should inform the buyer of the date of the classification of the exposure as non-performing.
