FA CanDo Task 7
Does anyone who has recently passed want to PM me to discuss this topic? I received feedback after my first two attempts. This was the question I completely redid; the rest I just updated. I was told on my third fail that it was one of the two needing the most improvement.
What I did was look at the following assumptions based on actual experience: 1. Exchange Rate. We were told this was equal to 1.11 instead of 1.04, so I recommended that 1.11 be used to reflect actual experience. 2. Inflation. The way I did this was I subtracted out labor costs from total costs, since labor costs were not impacted by inflation. Then I took the ratio of the prior quarter's to the current quarter's costs to estimate inflation, which was on average around 0.9% per quarter. I recommended this amount be used. 3. Decay rate. I backed into this number using "g" as it was defined in the instructions and found the decay rate using the following equation: 1(g(current)/g(prior))^(1/#periods in prior quarter). This was around 4%, which I suggested be used. 4. Labor costs. I tried to see if there was a linear relationship. To do this, I took the difference between the current and prior quarters' costs, then divided by the change in "g" over the quarter. There was not a clear relationship by doing this. Variable amounts were all over the place from quarter to quarter. So then I decided to see if there was a strictly variable cost without a fixed cost. To do this, I took the current quarter's labor costs and divided them by the current quarter's "g", and found there was a relationship of around $6k for two shifts and around $2.5k for one shift, consistently by quarter. I suggested this formula be used in the model. 5. "Other" costs  Delivery, equipment, and energy. I can tell that these have been lower than expected, but since the breakout was not provided for the individual components, I can't determine which costs are not in line with expected. I was able to determine "other" costs were lower than expected by taking the sum of $4.5million for two shifts or $2.5million for one shift (energy costs), $1.00 per oz of gold excavated (delivery cost), and $100k (maintenance and repair), then multiplied them by expected inflation per quarter. I then stated that I wasn't able to determine a good way to analyze investment yield or cost of capital using the data provided. If additional data is provided on those items, I would be able to conduct an experience study on them. What am I doing wrong?

I didn't include any graphs, although I did have an appendix showing my numerical results. I.e. what I expected vs. actual (with "other" costs broken out, etc). Do you think this was part of the reason I failed?
I'm really at a loss here, so any advice at all as to what people who passed did would be appreciated.

I didn't pass the FA on my first attempt and they listed Task 7 as one of mine that needed the most improvement, so I'm interested in feedback from people who have passed the FA, not from people who are awaiting results.
After accounting for the fact that my Task 7 response was shorter than all of the others (might showing the grader that I spent less time on it?), and after accounting for the fact that I did all of the usual expected calculations on the data given, I can only find one area for improvement: explaining my methodology a bit more. Instead of saying "I did an actual to expected analysis", should I explicitly state for each variable I compared actual experience to the modeled experience and used the difference to make a recommendation?

What is the statistical tool or analysis usually used to confirm a linear relashionship between X and Y? You should use it to determine a and b. The decay rate is stochastic. Is it possible to use experience data to calibrate the parameters of the normal distribution for future projections? Try to reproduce the formulas from task 16 with the data of task 7. It will help you understand how the different parameters affect the final result. Finally justify each of your recommendation, explain your method and summarize yours results. Good luck!

It was my understanding that the original parameters were based on assays (which only involve small samples). On the other hand, the actual experience of the gold yield (over the past 5 years) involves extracting TONS of ore from the ground. Hence, I would have thought that the experience data would be more credible than what was used to estimate the original parameters. Any thoughts?

Noteworthy: Decay rate is not on the scenarios and assumptions tab. I mentioned it would be worth looking at, but technically not part of the question.

Agreed but it costs nothing to add a few lines about it just to make sure you don't miss some important points. Better be safe than sorry.

What have you used the hedging factor for? Is that variable or value being calculated here?
