PRMIA 8010 Exam - Topic 1 Question 39 Discussion

Posted by Ronny on Dec 21, 2023 at 12:41 AM

The cumulative probability of default for a security for 4 years is 11.47%. The marginal probability of default for the security for year 5 is 5% during year 5. What is the cumulative probability of default for the security for 5 years?

Suggested Answer: B

Volatility clustering leads to levels of current volatility that can be significantly different from long run averages. When volatility is running high, institutions need to shed risk, and when it is running low, they can afford to increase returns by taking on more risk for a given amount of capital. An institution's response to changes in volatility can be either to adjust risk, or capital, or both. Accounting for volatility clustering helps institutions manage their risk and capital and therefore statements I and II are correct.

Regulatory requirements do not require volatility clustering to be taken into account (at least not yet). Therefore statement III is not correct, and neither is IV which is completely unrelated to volatility clustering.

Totally agree, 16.47% makes sense!

Wait, how does that add up? Seems off to me.

I think it should be 16.47% total.

Alyce 11 months ago
Yeah, and the marginal for year 5 is 5%.

Cumulative default for 4 years is 11.47%, right?

I feel like the answer might be around 15.90%, but I can't quite remember how to derive that from the given numbers.

I think I practiced a similar question where we had to calculate cumulative probabilities. If I recall correctly, it might involve some kind of multiplication for the non-default scenarios.

I’m a bit unsure about how to combine those probabilities. Is it just adding them together, or do we need to adjust for the overlap?

I remember that to find the cumulative probability for 5 years, we need to consider both the previous cumulative probability and the new marginal probability.

Wait, I'm a little confused. Isn't the cumulative probability supposed to be less than 100%? I'm not sure if just adding the two probabilities is the right approach here. Let me think this through step-by-step.

This seems straightforward enough. I'll just add the 11.47% and 5% to get the 16.47% answer. Can't be too complicated, right?

Okay, I think I've got this. The cumulative probability for 5 years is the cumulative probability for 4 years plus the marginal probability for year 5, which is not the same as just adding them. I'll need to do some calculations to get the right answer.

Hmm, I'm a bit unsure about how to approach this. Do I just add the 11.47% and 5% together? Or is there some other formula I should be using?
NO
Norah 1 year ago
This looks like a straightforward probability calculation. I'll need to combine the cumulative probability for 4 years with the marginal probability for year 5 to get the final cumulative probability.

The solution seems logical to me. Selecting the new report object and updating the layout should meet the goal of configuring the default Purchase Order report.

The question is asking about EDI transactions, so I'll focus on my knowledge of those to try to determine the correct answer.

I'm not sure, but I think the answer is C) 15.90% because we need to subtract the marginal probability from the cumulative probability for 4 years.
