Confusion on 3-year profit target.

Hi! -- I have a clarifying question about this calculation.

So the case says the following

  • The goal of the client is to increase profits by 10% in three years
  • The client’s most recent profit was $500M

So it seems you could achieve this goal in 2 ways, depending on how you interpret it:

1. making 500M x 1.1 = 550M in year 3 alone (so 50 M extra) 

2. or making 500x3x1.1 = 1650M total across the 3 years (so 150 M extra)

However, at the end of the calculation, it is assumed that the combined profit target across the 3 years is just 50 M. I am confused why this is correct, as 50 M is not a 10% increase on what you otherwise would've made across 3 years (1500 M)

Based on the wording, it seems accurate. In a live case, you would have needed to clarify your understanding to ensure you’re on the same page.


So the interpretation was based on the goal to increase profits *in* 3 years (for year 3) *by* 10% (assume it is relative to today). Also, for a business, the year 2 profits would be irrelevant as the goal is measured on performance of year 3, so no ramp up needed

This is where I was confused as in the calculation it looks like they are considering the year 2 profits -- and then the sum of year 1 and 2 profits is compared to the profit target in year 3 alone.
Would it not make more sense to compare the profits in just year 3?

My understanding when I first read the question is that it seems quite straightforward : we want to increase our current profit (500M) by 10% in 3 years, meaning simply an increase of 50M in year 3. Of course you could clarify this orally in a real case scenario.

This was my initial understanding, but I am wondering then why you would be adding in year 2 revenues (step 5 and 6)?

Hi Emily,

Thanks for solving my case! I confirm that the goal is to increase profits by $50M over the next three years. I agree the text is not very clear in terms of that, I will edit it to clarify it, thanks for pointing this out.

Best,

Francesco

Hi Francesco,
To clarify, if we are adding up the new profits of yr1,2&3, I am wondering why you don't compare this to what the profits would've be for all 3 years? Since you used to make 500M/yr wouldn't you have made 1500M in 3 years and thus 10% of this is higher than 50 M?

Hi Emily, happy to clarify, as the goal is to achieve $50M more overall within 3 years, I will edit the text to make it clear using the absolute number rather than the percentage, which could indeed be confusing. Hope this helps.

Hi Emily,

I see that Francesco will edit the rather ambiguous wording, which should resolve the issue.

You can find more on this topic here: How to succeed in the final interview round.

If you would like a more detailed discussion on how to best prepare your application files, for your upcoming pre-interview assessments and/or interviews, please don't hesitate to contact me directly.

Best,
