The reference date (initial recognition) that is used to assess and determine a significant increase in credit risk (SICR). This date differs from context to another. For term lending, it is the date the facility is placed at a customer’s disposal (actual transfer of funds). For wholesale revolving facilities, it  is denotes the date of the last substantive credit review or, if  later, the date the facility is made available to the customer.

For current accounts/ overdrafts, it is the date on which an account is opened, or if later, the date of initial extension of the facility or limit increase. For retail cards, it represents the account opening date or, if later, the date the card was placed under time-bound regular review or the date of a certain limit upward adjustment.

It is known for short as DOIR.
