For the treatment of cured defaulted exposures, a probation period of 90 days with no default triggers must apply before the exposure is moved back to a non-defaulted status. According to Article 178(1)(b CRR) default shall be considered to have occurred with regard to a particular obligor when the obligor is more than 90 days past due on any material credit obligation.
However, if the material arrears fall below the thresholds, the arrears counter will reset to 0. Should the probation period of 90 days with no default triggers apply before the exposure is moved back to a non-defaulted status?

A probation period of 90 days must be met since the day a default exposure does not meet any default criteria triggers.

Minimum conditions for reclassification of a defaulted exposure or obligor to a non-defaulted status, for the purposes of the application of Article 178(5) of Regulation (EU) 575/2013 (CRR), are specified in the Guidelines on the application of the definition of default under Article 178 of Regulation (EU) No 575/2013 (EBA/GL/2016/07).

Except for situations referred to in paragraph 72 of said Guidelines (distressed restructuring on a defaulted exposure is subject to a probation period of at least one year – see also Q&A 4867), all conditions from paragraph 71 of such Guidelines should be satisfied for the reclassification of a defaulted exposure or obligor to a non-defaulted status.

As no trigger of default should continue to apply during a 3-months minimum probation period in accordance with point (a) of paragraph 71 of the Guidelines, no indication of unlikeliness to pay should be met in accordance with Article 178(1)(a) CRR and no material amount should be past due in accordance with point (b) of Article 178(1) CRR during this period.

Furthermore, as part of the assessment required by point (d)  (d) of paragraph 71 of the Guidelines, point (b) of that paragraph paragraph  required that the institution takes into account the behavior of the obligor during this probation period before reclassifying a defaulted exposure to non-defaulted status, and thus the institution should consider any  past due amount during this period in the analysis of the behavior of the obligor.
