• ICAAP Submissions Probability of Default (PD) Calculation

    Dec 14 2010 · One method of estimating Probability of Default (PD) is to use historical time series data. The data are grouped by rating grade and a PD estimate is derived for each rating grade. The PD therefore gives the likelihood for obligors with a particular rating grade at the start of a given time period defaulting within that time period.
