+Article 182 1. |
Article 182 1.In quantifying the risk parameters to be associated with rating grades or pools, institutions shall apply the following requirements specific to own-conversion factor estimates:
(a)
institutions shall estimate conversion factors by facility grade or pool on the basis of the average realised conversion factors by facility grade or pool using the default weighted average resulting from all observed defaults within the data sources;
(b)
institutions shall use conversion factor estimates that are appropriate for an economic downturn if those are more conservative than the long-run average. To the extent a rating system is expected to deliver realised conversion factors at a constant level by grade or pool over time, institutions shall make adjustments to their estimates of risk parameters by grade or pool to limit the capital impact of an economic downturn;
(c)
institutions’ IRB-CCF shall reflect the possibility of additional drawings by the obligor up to and after the time a default event is triggered;
(d)
in arriving at estimates of conversion factors institutions shall consider their specific policies and strategies adopted in respect of account monitoring and payment processing. Institutions shall also consider their ability and willingness to prevent further drawings in circumstances short of payment default, such as covenant violations or other technical default events;
(e)
institutions shall have adequate systems and procedures in place to monitor facility amounts, current outstandings against committed lines and changes in outstandings per obligor and per grade. The institution shall be able to monitor outstanding balances on a daily basis;
(f)
if institutions use different estimates of conversion factors for the calculation of risk-weighted exposure amounts and internal purposes it shall be documented and be reasonable;
(g)
institutions’ IRB-CCF shall be estimated using a 12-month fixed-horizon approach;
(h)
institutions’ IRB-CCF shall be based on reference data that reflect the obligor, facility and bank management practice characteristics of the exposures to which the estimates are applied. For the purposes of the first subparagraph, point (a), where institutions observe a negative realised conversion factor on their default observations, the realised conversion factor on those observations shall be equal to zero for the purpose of quantification of their IRB-CCF. Institutions may use the information of the negative realised conversion factor in the process of model development for the purpose of risk differentiation. For the purposes of the first subparagraph, point (c), IRB-CCF shall incorporate a greater margin of conservatism where a stronger positive correlation can reasonably be expected between the default frequency and the magnitude of the conversion factor. For the purposes of the first subparagraph, point (g), each default shall be linked to relevant obligor and facility characteristics at the fixed reference date defined as 12 months prior to the date of default. 1.
