I do not have practice material for IRR – that was an offer to students who were actually on the course at the time.

You presumably have a Revision/Exam Kit from one of the ACCA approved publishers (if you do not then you should buy one immediately because it is vital to get lots of practice on exam standard questions). Your Revision Kit will have plenty of questions calculating IRR for you to practice.

In addition, since IRR itself is only revision of what was examined in Paper F2, you will find more examples in the Paper F2 lecture notes and free lectures.

In example 5 on annuity… when we get the answer 80440 as u did in the video, do we not have to discount it further to get a present value in year 0..?
its like we calculated the value in year 4 but year 0 (now) we didn’t..

The first receipt is at time 4, and because there are 10 receipts, the last receipt is at time 13.

You can get the answer in one of two ways – it doesn’t matter which, so whichever you find more obvious.

One way is the take the annuity factor for 13 years (which would give a PV for all 13 years) and subtract the annuity factor for 3 years. That leaves you with a factor for time 4 to time 13.

The alternative is to take the annuity factor for 10 years (because there are 10 years of flows), and then discount by the ordinary present value factor for 3 years (because the annuity starts 3 years at time 4 instead of time 1).

Both ways give the same answer (they will be a little different because of the roundings in the tables, but that is irrelevant in the exam).

(If you are still unsure it will help you to watch the relevant F2 lectures because it is revision of F2)

First, there is no such thing as an ‘advanced perpetuity’! I can only guess that you mean a perpetuity that starts later than at time 1 – but that is still a perpetuity by definition!!

Second, it is extremely rare for perpetuities to occur investment appraisal questions at Paper F9 (they are relevant when calculating cost of equity, but that is dealt with in the lectures on the cost of equity). You will find it difficult (if not impossible) to find any past exam questions in the past five years that have a perpetuity existing in an investment appraisal question. We are teaching to pass the exam, not simply play around with numbers.

Thirdly, dealing with annuities (which do occur often in F9) and perpetuities (which don’t) are both pure revision from Paper F2, so if you have forgotten how to deal with them then you should watch the relevant F2 lectures.

In this Annuity Lecture , why you have removed the 1-3 years although we know that the first Receivable would be in Year 4 and last would be in Year 13 so I am little confused that why the 1-3 years are removed .

Hi Hailu, the video works for me. The problem could be the internet browser you are using. You may consider a different internet browser (firefox, google chrome, operamini, etc)

The standard of your teaching is simply OUT OF THIS WORLD!! You take so much care in highlighting the crucial points and normal Pitfalls, for students. I cannot thank you enough. My God bless you for your beautiful contribution.

Thank you so much Mr Moffat. YOu are an amazing teacher . Everything makes so much sense now and in fact I have gone from hating this paper to loving it. Open tuition thank you.

I think the interpretion on Qn 5 pg 40 is wrong:Look at how i think it should be counted and end of the tenth year would year 14 and not 13
Receivable in 4 years time:
year 1 2 3 4 5 6 7 8 9 10 11 12 13 14
There after for total 10 years 1 2 3 4 5 6 7 8 9 10
Am i correct to think this way????
Thanks

hi, john. trying to calculate the answer to Q7 on page 41 by using the other method, and the answer was different. the way i’ve done it was: if there will be receiveables from year 5 to infinity, then on year 5 the discount factor will be:
1/0.05 x 0.784= 15.68 . i agree the way that have been shown in the vid is less confusing and if i was right then the figures should be the same. can you help, please? thank you!

The formula 1/r is the discount factor for perpetuities.
So if you assume receivables happen from time=0 to time=infinity, the discount factor for this example is 20, and the present value of 18,000 annually in perpetuity is 18,000×20 = 360,000. (This means if you put 360,000 in the bank now you will get 18,000 every year)

The only thing you are left with now, is to remove years 1-4.
You can do this by removing each year individually (by multiplying 18,000 by the 1,2,3 and 4 year discount rate in the present value table) or by removing years 1-4 in one lump sum by multiplying 18,000 by the discount rate in the annuity table for year 4.

The Annuity table is simply the present value table, summed to include all preceding years.

In this example…
Year 1 discount factor = 0.952
Year 2 = 0.907
Year 3 = 0.864
Year 4 = 0.823

Because net cash flow is the same each year (18,000), instead of multiplying 18,000×0.952, and 18,000×0.907, and 18,000×0.864 and 18,000×0.823, we can instead say that it is the same as 18,000x(0.952+0.907+0.864+0.823) = 18,000 x 3.546.

So the answer would be (18,000 x 1/0.05) – (18,000 x 3.546).

I may be mistaken, but lukedavidizard seems to be just repeating what is in the video lecture!

The approach that you are trying to take is fine, but you have made one error.

The discount factor for a perpetuity is certainly 1/r, and if the perpetuity started in 1 years time then this would give the present value (the amount now).
However, the perpetuity starts in 5 years time, which is 4 years later. So multiplying by 1/r would give a value 4 years later – i.e. at time 4. To get back to the present value you would then need to multiply by the ordinary discount factor for 4 years (not 5 years as you have written).

If you do this then you will get the same answer. (In fact it will probably be a little different, but this will be simply due to rounding and does not matter).

hasanali95 is correct – since you are given tables you do not need to calculate.
However, I would try and sort out your calculator – you will need to do other things with it even though you will not need to calculate the discount factors (which are not percentages by the way!) 🙂

Thank you for these videos open tuition, the tutors are excellent, ive learnt more from these videos in the last few days than what i’ve learnt at school in the last year!

Hi John,

You mention in the lecture that you can provide practice material for IRR. I’d certainly like to have that if it’s not a problem.

Thanks.

Dear John Sir,

In this Annuity Lecture , why you have removed the 1-3 years although we know that the first Receivable would be in Year 4 and last would be in Year 13 so I am little confused that why the 1-3 years are removed .

John Moffat says

The 13 year annuity factor is the total of the discount factor from years 1 to 13 inclusive.

We want the total factor for years 4 to 13, so we need to remove the total for years 1 to 3, i.e. the 3 year annuity factor.

aliimranacca007 says

But 1st 4 years plus next 10 year become total 14 how 13 ? i am confused plz tell me 🙁

John Moffat says

The first receipt is in 4 years time – time 4.

The second receipt is at time 5

The third receipt is at time 6.

If you carry on (and use your fingers to count!) then if there are 10 receipts the last receipt is at time 13.

Yes – I make this clear in the very first lecture for F9!!!!

You get given the present value tables, the annuity tables, and a formula sheet 🙂

Yes – each step is marked separately (they do not just mark the final answer) 🙂

Question says the “first recieable in 4 years”.ie it assumes the first reciept is by the end of fourth year,and follows until 10th year completes.

John Moffat says

I know that the wording may confuse, but it is likely wording in the exam.

The first receipt is in 4 years time – time 4 – and there are 10 receipts in total (not 10 receipts in addition).

So for 10 receipts in total, the receipts are at times 4 5 6 7 8 9 10 11 12 and 13.

John you are amazing in helping us.

danielglover says

Using better gramma in the lecture notes would make things a lot clearer. Ex5 p.g.40 can be interpretated as 10 more years after the 4th year.

John Moffat says

@danielglover, No – the grammar is perfectly correct.

It specifically says “for a total of 10 years”

That does not mean 10 extra years, it means 10 years in total.
