Hi,

This looks like it is an extensive topic, as SAS offer a training course: https://support.sas.com/edu/schedules.html?ctry=gb&id=2394

Check out a similar thread here that discusses LGD:

EAD is often simply just the loan exposure - both drawn and undrawn added. There is really no need to model this. By analysing in-default loans it is usually quite easy to confirm if EAD can be simply the total exposure or not. Sometimes this figure needs to be adjusted for various products. For example credit cards are often allowed to go significantly overlimit so in this case EAD might be set to 105 or 110 percent of exposure. Also with transaction accounts with shadow limits then EAD may need to be adjusted.
