    Incorrect calibration & Data problems

    Hi David, "* model spec: I select an POT EVT model to estimate VaR and ES " I wonder if this kind of mistake should belong to the "incorrect model application" category ("wrong model")? BTW I am also confused in that one example of "incorrect model application" is "insufficient # of...

    capital requirement and RWA under IRB

    Hi David, I wonder if the calculation of capital requirement (K) and RWA under IRB is limited to credit risk, because it uses LGD, PD, EAD? or is IRB for credit risk only? "RWA (IRB) =12.5*EAD*K K =LGD*f (PD)* f (M,b)" Thanks.

    capital ratio

    Hi David, Does the capital ratios for each individual risks (credit, market, op) all need to meet 8% requirement? or as long as the total capital divided by the total RWA is at least 8%, then it is fine? thanks.

    Attribution of Capital

    Hi David, thanks for your great answers!! "EC for OpRisk = WCL(confidence); i.e., following Basel, we would include EL" This does not look familar. maybe i have not studied it yet.. could you elborate or could you indicate which reading/AIM is for this? Thanks.

    Attribution of Capital

    Hi David, It seems some economic capital should also be attributed to market risk and Op risk (in RAROC). I wonder if that means EL + UL = total VAR than credit VAR? Thanks.

    Super-senior tranche

    Hi David, That article led me think that SPE and the underwriter of the CDO needed to set up SS, and be the conduit for SS... It seems that is wrong.. thanks.

    Super-senior tranche

    Hi David, Thank you! It makes a lot of sense. I was puzzled because I read the following article (see page 6). It gave me the feeling that the super senior is one of the CDO tranches.. http://www.adelsonandjacob.com/pubs/CDOs_in_Plain_English.pdf "The "super senior" tranche in the...

    Super-senior tranche

    Hi David, Is the CDO's SPE the CDS protection seller of the unfunded portion of the reference portfolio corresponding to the Super-senior tranche? I am asking because accoring to your sceencast, it seems the protection seller is a different entity.. The Super-senior tranche is one of the CDO...
