The authors of this paper address some issues to do with IFRS 9 and explain how to determine if an instrument has suffered serious deterioration in credit risk.
A point-in-time–through-the-cycle approach to rating assignment and probability of default calibration
This paper proposes a methodology for constructing TTC rating grades and assessing the resulting degree of PIT-ness.
In this paper, the authors show how one can use a certain class of models for modeling portfolios such as large corporates, banks and insurance companies.
The authors of this paper contend that recent evidence indicates that benchmarks have, over the last eleven years, exaggerated default risk for nonfinancial corporate entities.
Echoing remarks made earlier in the week, William McDonough, president of the New York Federal Reserve Bank, stressed that the results of the third Quantitative Impact Statement (QIS3) being compiled at the moment show that few changes will have to be…
