P2.T6.142.1
Hi All, 142.1. Which of the following inputs is NOT required to estimate the probability default (PD) under the Merton/KMV model? a) Riskfree rate b) Firm (asset) volatility c) Debt capital structure (default point) 4. d) Market value of firm equity The inputs to estimate the PD are the Firm asset value, Debt value, Firm volatility, and drift. Could someone explain how to...

Merton drift in DD
Hi All, P2.T6.R43 I am trying to conceptually understand how the DD value is calculated statistically. The numerator is the expected value of the price, and the denominator is the standard deviation. My question relates to the numerator. Assume T-t=1 ln(Vo/K) is the current log "return" at T=0. We then add what I assume is the expected drift until maturity (r-(sig^2)/2). How am I supposed...

Total Return Swap (Crouhy) - Figure 12-7 - mistake?
many thanks, David! Apologies,I was referring to Crouhy's first edition in my question (there it is Figure 12-7). Now it makes good sense.

MtM and Exposure for Netting
Hi @arkabose Yes, agreed. Your circled item is from the source (Gregory) and it's not listed in his errata that I can see (). However, I agree with you. This looks like a mistake to me (sorry). Your second paragraph, of course, is CORRECT: in a fixed cross-currency swap, the counterparty who pays the higher interest rate has a positive expected future M2M; i.e., the higher relative rate, per...

2016 GARP PQ - Question 52 -Netting
Hi @no_ming In this question, the type of instruments don't really matter as the question is giving you the mark-to-market value ("current market value") of the positions. Credit exposure is max(value, 0). So the credit exposure here without netting is 54, but with netting it is only 21: Without netting: max(0, +21) + max(0, -33) + max(0, +33) = 54 With netting: max(0, 21 - 33 + 33) = 21

Excess spreads question~
Hi @no_ming Your question is good because sometimes default is assumed to refer to only the principal (as your solution infers), however here (in my opinion) the question does specify "accumulates 6.625 mm of losses from defaults and unpaid interest." And, this is natural (yes?): losses should refer to both unpaid principal and unpaid interest. So, given the phrasing, appropriate would be...

PFE & EE Question~
@no_ming Re: In another word, not only EE, if Sigma and mean increase, PFE, EPE etc. also increase, is that right? Yes, if you increase µ or σ then you are shifting or "expanding" (dispersing) the normal distribution, so the x% PFE will increase, in the same way that higher volatility or lower return will increase (absolute) value at risk because there x% tail (quantile) is further into loss...

Considerations about commitment fee and EAD
Hi to all! If I understood correctly, banks apply a commitment fee (fixed percentage) on the undrawn portion of a credit line to hedge the further expected loss associated with that credit exposition. So you have to pay more if you are using a small drawn portion of the credit line. Now, given the fact that a firm with an high rating (such as AA or A) will only use a small part of the credit...

Credit Exposure
Hi @Stuti It's the same square root rule that let's us scale volatility/VaR per sqrt(ΔT) but therefore importantly it is conditional on the same i.i.d. assumption, namely that the returns of the credit risk factor are independent. Further, this is the simplest possible credit exposure profile; i.e., a single i.i.d. credit risk factor. For example, in a swap, sqrt(ΔT) tends to characterize...

CDS pricing question!
Hi @no_ming Yes, on one level, that's correct: the question implies an increase in price and, if we naively assume that the price determines the collateral posted (as the question implies), then the price increase implies additional collateral is posted. As discussed, most of the price movement should be fundamental (i.e., changes in the reference's credit quality) but, as is always the case,...

Hi @ami44 In regard to to Gregory's Table 12.6 above, I would just add: On the total line, there is only a summation of standalone CVAs (392,973) which is maybe not so useful except as as unrealistic, undiversified CVA (but diversification here, just exactly as @ami44 says, is a dynamic really due to the netting agreement in the netting set) versus the "actual" (i.e., diversified at the...
