Article 4
Short run default rates of a rating category where a sufficient number of credit ratings is available
The short run default rates of a rating category shall be calculated over a 3-year time horizon as a ratio where:
the denominator represents the number of items assigned the same rating category present at the beginning of the time horizon;
the numerator represents the number of items referred to in point (a) that have defaulted prior to the end of the time horizon.
Items shall be considered to be defaulted items to be included in the numerator specified in point (b) of paragraph 2 where any of the following types of event has occurred:
a bankruptcy filing or legal receivership that will likely cause a miss or delay in future contractually required debt service payments;
a missed or delayed disbursement of a contractually required interest or principal payment, unless payments are made within a contractually allowed grace period;
a distressed exchange if the offer implies the investor will receive less value than the promise of the original securities;
the rated entity is under a significant form of regulatory supervision owing to its financial condition.
