PRA held a virtual meeting with firms that are using an internal ratings-based (IRB) model to calculate capital requirements for residential mortgage exposures. The meeting was intended to enhance dialog between PRA and firms before model submissions. At the event, PRA presented on the most relevant cross-firm modeling issues and further discussed its expectations regarding the development of hybrid probability of default (PD) and loss given default (LGD) models.
PRA was expected to provide further clarifications on common cross-firm modeling issues while firms were expected to highlight risks and challenges to internal model governance, implementation timelines, and submission to PRA. PRA provided an overview of its expectations regarding the development of hybrid PD models, highlighting the most common modeling issues in the areas of calibration, measurement of cyclicality, modeling of sub-portfolios, and margins of conservatism. PRA also outlined its expectations on the development of LGD models, highlighting the most common modeling issues with respect to downturn periods, probability of possession given default, use of rating scales, and treatment of unresolved exposures.
This meeting followed the publication of the policy statements PS11/20 titled "Credit risk: Probability of default and loss given default estimation" and PS12/20, which addresses potential inconsistencies in practices across firms in relation to the capital treatment of retirement interest-only mortgages. PS11/20 finalized the policy related to PD and LGD estimation and updated SS11/13 on internal ratings-based approaches. SS11/13 covers the principal topics of corporate governance, permanent partial use and sequential implementation, overall requirements for estimation, definition of default, PD, LGD, exposure at default, validation, income-producing real estate portfolios, and notification and approval of changes to approved models.
