0:06 So for modified IR it's an improvement over
0:08 over
0:11 the traditional IR that you know. So
0:14 which means what the modified IR tries
0:17 to do is to
0:19 cater for those weaknesses of
0:22 traditional IR. And if you recall those
0:27 weaknesses that we learned in FM, the
0:29 first one is the fact that under the
0:31 traditional IR
0:34 there's an assumption that all the cash
0:37 flows that a project generates all those
0:41 cash flows are invested at IR a constant
0:43 rate and we know that this is not
0:46 practical because IRRa is like an
0:49 indication of your cost of capital. So
0:51 you cannot say the cost of capital is
0:54 the same thing as investment rate.
0:56 Your financing rate is your cost of
0:58 capital. So if there are cash outflows
1:00 that is the money you have kind of
1:03 borrowed. So it makes sense to use a
1:05 financing rate for that. But the inflows
1:07 that you are generating cannot be
1:09 reinvested at the same rate. It is not
1:13 practical and that's a weakness that MR
1:16 will cover. Likewise,
1:17 if you look at a project, there's a
1:19 possibility that a project will have
1:21 more than one IRRa. And that is why we
1:24 say that the traction does not give a
1:27 unique figure because you can have more than
1:32 one IRR
1:42 and that that is a confusion.
1:47 That's another weakness that MR has come
1:51 to fix. And likewise, IRRa is not a
2:02 because even if your IRRa says it's 10%,
2:04 it doesn't mean that the return on that
2:07 investment is 10%. So because of that is
2:10 just difficult to interpret
2:12 especially for nonac accountant.
2:16 And also sadly actually
2:20 this traditional might contradict NPV
2:22 decision. So it might give a contradictory
2:24 contradictory
2:27 result. So IR might be saying don't do
2:29 the investment NPV saying do the
2:32 investment. Remember what we learned in
2:34 FM is that if there is such
2:38 contradiction NPV supersede. So another
2:48 NPV decision.
2:50 decision.
2:55 So all these are weaknesses of
3:01 traditional IR and that is why we now
3:04 have MIR
3:06 which is a modified version that
3:08 that
3:11 actually makes life easy for you because
3:14 for MR interestingly
3:17 it's a return measurement. So if you get
3:19 MR of 10% return on investment is deemed
3:23 to be 10%. It will never contradict NPV.
3:26 It is unique and it doesn't make this
3:29 constant rate assumption for both inflow
3:31 and outflow. For MR you can work with
3:34 two rates, two different rates. All the
3:36 inflows are invested at reinvestment
3:40 rate and all the outflows are discounted
3:42 at the financing rate. And you will see
3:45 an example which we're going to do.
3:47 Yeah, but in terms of decision is the
3:50 same as what you have in IRRa. You make
3:52 a decision whether to do an investment
3:56 or not when M IR is greater than cost of
3:58 capital. Remember this is similar to
4:01 what you had for traditional IR because
4:04 the decision to do investment is done
4:06 when IR is greater than cost of capital.
4:10 So that is just the similarity between
4:14 both uh methods.
4:17 Now the next question is how do we
4:20 calculate M IR?
4:22 How do we calculate? What is the
4:24 formula? And there are two formulas I'm
4:26 going to show you. But I'll start with the
4:27 the
4:29 simple one which you normally see in
4:33 your ACC exams. They will give you the M
4:36 formula to be equals to
4:39 the present value of your inflows or the
4:42 investment or the return cash flows.
4:44 I'll call it inflows to make it simple
4:57 raised to power 1 / n
5:01 * 1 + cost of capital
5:10 This is a popular formula you will see
5:13 in exams. However, this formula is
5:17 hardly useful. Yeah. Because this
5:20 formula only works
5:22 only when
5:27 the cost of capital is the same as
5:30 reinvestment rate.
5:33 So what we are saying is that the cost
5:36 of capital is the same thing as the rate
5:40 you need to use to reinvest the inflows
5:43 that the project is generating. Yeah.
5:44 You can have a question like that but
5:47 it's real. Yeah. Because then it makes
5:50 no difference from what we've been
5:53 learning because the reality is
5:56 MR is really really useful when you have
5:59 some complications. I mean such that you
6:01 are able to account for different
6:03 reinvestment rates from the cost of
6:06 capital right
6:08 and we're going to work some examples
6:12 which um remember R is cost of capital N
6:14 is the number of years deter of the
6:16 project and if you just to work an
6:19 example quickly for you to see how you
6:20 can apply this formula let's say you
6:23 have year zero you have year one cash
6:27 flow year two cash flow year three and
6:32 year four. So, initial outlay of 20,000.
6:37 You have 8,000 inflow in year 1, year 2, 12,000.
6:39 12,000.
6:42 Let's see. You have 4,000 here and
6:45 2,000. So, let's say a project with a
6:49 cost of capital of 8%. And for this one,
6:51 we're going to assume that this cash
6:55 flows of 8,000, 12,000, 4,000 are all
6:58 reinvested at the same 8%. So, which
7:00 means the cost of capital and the
7:04 reinvestment rate are both the same. In
7:06 that case, we can apply this formula
7:08 here. So, that's what I'm going to use
7:11 now. So first of all we need to
7:13 calculate the present value of all the
7:15 cash flow which means we need a discount
7:37 So we look at the PV table. We need to
7:41 pick the discount factor for at 8% for
7:44 year 0 we know it's going to be 1
7:50 and uh for year 1 that is 0.9
7:54 2 59
7:57 year two no I'm looking at anointed
8:05 I need the PV
8:09 Yes. So for year 1 under 8% you have 0.92
8:11 0.92
8:14 and for year one it's always going to be
8:26 0
8:29 two will be 0.8 8 573
8:51 zero. Okay.
8:52 So we know the discount factor. So we
8:56 can now get the present value 20,000 * 1
8:59 that remains 20,000.
9:02 Then we have 8,000 * 92
9:04 92
9:09 8,000 * 9259
9:15 that gives 7 4 07 12,000
9:17 12,000
9:20 multiply by85 73
9:22 73
9:25 that's 10
9:32 Then 4,000
9:35 multiply by.7
9:38 9 38 3175
9:46 and 2000 * 735
9:48 735 470.
9:54 So we have the PVs for all the inflows.
9:57 These are the four of them and we have
10:00 the PV for the outflow as well. So we
10:02 need to add all of these together
10:07 to get the PV of inflows total.
10:09 And if you add all of that together
10:13 quickly, plus 3175
10:22 + 747.
10:26 That gives us 22
10:29 339 22 339.
10:31 339.
10:33 So that's the PV of all inflows. So we
10:36 go back to our formula. This formula we
10:38 need to apply it now. So which means
10:43 you're going to have equals to 22 339
10:47 / 20,000. So you can ignore the negative
10:50 of the cash outflow in this formula. The
10:52 tenure of the project is four years. So
10:57 1 / 4 * 1 + 8%
11:00 everything minus 1. So let's deal with
11:06 this part quickly. So 22339 / 20,000
11:10 that gives 1.117.
11:18 1 / 4 * 1.08 08
11:21 10 - 1.
11:41 and then multiply by 1.08 08 that gives
11:44 us 1.11
11:49 then minus one that give us 0.11
12:00 Remember
12:03 the formula that we have used here is only
12:05 only
12:08 applicable when the cost of capital is
12:11 the same as reinvestment rate. When it
12:13 is different, you need to use a
12:16 different approach which is much more
12:18 realistic and that is the approach to
12:21 that I want to teach you now. Yeah. So
12:24 please pay attention to this approach to
12:27 to MR.
12:30 In this case the formula is different
12:32 and the formula is
12:34 is
12:36 no more present value for the inflows
12:38 but rather the terminal value of the inflows
12:40 inflows
12:43 divided by the present value of the
12:45 outflows. So add flows remains the
12:47 present value.
12:50 Then all of that
12:55 raised to power 1 / n minus one. So you
12:58 can see the formula is a bit shorter but
12:59 you still need to understand how you
13:02 apply it. Remember TV means terminal
13:06 value. Please take note.
13:08 So which means you need to learn how to
13:10 calculate terminal value. Terminal value
13:12 is just from the word terminal. terminal
13:14 means at the end. So you are saying for
13:16 every cash that we generate take for
13:19 instance this 8,000 what is the value at
13:20 the end because for this project that is
13:23 4 years the end of the project is end of
13:25 four years
13:28 this point. So we want to calculate the
13:30 terminal value you're going to be asking
13:32 yourself this 8,000 what will be the
13:34 value at year four? So which means you
13:36 will need to reinvest it once you make
13:38 this 8,000 in year 1 you invest it year
13:41 2 1 year 2 years 3 years. So you're able
13:44 to invest it for 3 years but at
13:46 reinvestment rate. So this time around
13:49 it's still going to be at 8%. 12,000 you
13:52 reinvest for 2 years, 1 year, 2 years.
13:55 4,000 you invest just one year and 2,000
13:57 you don't have time to reinvest because
13:59 it's just coming in year four. So if we
14:02 want to use that
14:05 understanding to test this formula. So
14:06 it means we need to calculate the
14:09 terminal value of all the inflows.
14:12 So which we're going to start with the
14:16 first one 8,000. So for the 8 for year 1
14:19 the terminal
14:23 cash flow for year 1 will be 8,000
14:28 invested at 8% for 3 years raised to
14:30 power 3. So we need to know what that
14:33 will be quickly.
14:37 The same thing we do for year two. Year
14:38 two we're going to invest. How much
14:40 would we make? We're going to make
14:42 12,000 in year two, but we're only going
14:44 to invest it over two years. We only
14:46 have two years left,
14:49 but still at the same 8%. Raise the
14:58 is just um 4,000
15:06 and yet four is 2,000. This one we don't
15:09 have time to reinvest it. So this one
15:13 remains 2,000. This one will we can
15:17 reinvest just for one year at 8%. So
15:19 let's see. So 1.08
15:23 raised to power 3
15:25 multiply by 8,000 that will be the
15:28 terminal value of 8,000. So which means
15:31 this 8,000 that we made in year 1 if we
15:36 reinvest it at the 8% by year 4 that
15:38 will be the value. The same thing we'll
15:45 * 12,000
15:48 becomes 13 996.
15:50 996.
15:54 Then the last one * 4,000
15:56 that's 4320.
15:58 So we now need to add all the terminal
16:02 cash flows together to get
16:05 what the total terminal value of all our
16:14 that gives 30 393.
16:17 393.
16:21 So now we know this part. We also know
16:23 PV of outflows because it will remain
16:26 20,000 because there's no outflows
16:28 during the year which is possible and
16:30 I'm going to work an example with that.
16:32 But for this question the outflow is
16:34 just beginning of the year. So the P
16:37 remains 20,000.
16:39 So which means we can just apply this
16:45 formula easily and that means our mirror
16:47 will be equals to 30 393
16:49 393
16:52 / 20,000
16:56 raised to power 1 / n which is four. So
17:07 minus one. So let's divide by 20,000.
17:09 then raised to power 1 / 4 that's like
17:12 raised to power.25
17:16 that gives 1.13
17:27 which is the same thing as 11.03%.
17:30 Can see the two formulas give us the
17:34 same answer. Yeah.
17:35 And that is why I'll prefer this
17:38 approach because with this approach two
17:41 regardless of your situation it will
17:43 give you the answer unlike approach one
17:46 that will only give you the right answer
17:48 only when CO is the same as your
17:51 investment rate. Now let's work a
17:53 question whereby the
17:55 the
17:57 investment rate is different from
18:00 financing rate. Then that will add a
18:02 proper spice to what we're talking
18:05 about. So look at this investment. Yeah,
18:08 you have year zero
18:11 um year 1 cash flow, year two, year
18:16 three, year four and year five. So year
18:20 0 let's say remains 20,000 outflow.
18:24 That is the net for year 1. For year 0,
18:28 year 1 there's inflow of 4,000.
18:32 Year two there's net outflow.
18:36 Year three, another inflow of 6,000.
18:40 Year four, 7,600.
18:43 Let's say 10,000 here. So, let's work
18:46 with this. Remember the first thing is
18:48 you need to know your reinvestment rate.
18:50 So, let's say the question has given
18:53 reinvestment rate
18:56 at 6%.
18:58 and financing rate which means that's
19:05 at 9%.
19:08 And we need to calculate MIR. So you can see
19:09 see
19:12 all this cash flow 4,000 the inflow
19:15 6,000 that we made 7,600 we made we need
19:19 to reinvest it at 6%. Whereas all these
19:21 places where we needed money that we
19:25 spent money will
19:28 discount at 9%. Because our cost of
19:31 financing is 9%.
19:34 So which means we still need to apply
19:37 that formula which is this one
19:39 terminal value and present value of
19:41 outflows. So let's do the present value
19:44 of outflows first.
19:45 So for this one we know that our
19:49 discount rate discount factor
19:52 will be one at year zero. So the present
19:54 value remains 20,000
20:02 and this is another outflow but this can
20:05 factor will be different
20:09 because this is year two and it's still
20:12 going to be at 9%.
20:15 So this is at 9%. So we need to go to our
20:22 discounting table and look at 9% year 2
20:29 So that will be discounting factor at 0.842.
20:31 0.842.
20:35 And if I multiply 0.842
20:44 842 * 2000 that will give us the PV of
20:46 that outflow.
20:49 So we've gotten the PV of that outflow.
20:52 So for outflow we already know the total
20:54 is addition of these two and that will
20:57 give us 216 84.
21:00 84.
21:01 So we already know the PV of our
21:03 outflow. Now we need to know the
21:05 terminal value of our inflow.
21:08 Yeah, N is five as we can see. So what
21:10 we are left with now is the terminal
21:13 value of all the inflows. And from this
21:15 question we can see that we have four
21:19 inflows 4,000 6,000 this and this. So
21:21 which means we need to get the terminal
21:23 value for each of them. And terminal
21:25 value means we need to push forward
21:28 compounding at the reinvestment rate
21:29 because we're going to be investing it.
21:32 So this year 1 of 4,000 if we need to
21:35 reinvest it we we'll be reinvesting it
21:38 for how many years to be from year 1 to
21:45 year 2 year 3 that's 2 3 4 and likewise
21:49 like that. So for 4,000. So
21:52 So
21:54 so let's do terminal value. Let's do
21:57 like working one here. Terminal value of inflows.
22:03 So for year one where we have inflow of 4,000.
22:05 4,000.
22:10 We're going to multiply it by one 1 +
22:13 investment rate of 6%
22:16 and for 4 years. So that will give us 1.06
22:18 1.06
22:25 * 4,000
22:30 and that means for year one
22:31 inflow that we are getting by time we
22:34 invest it by the end of the investment
22:36 life of 5 years this money would have
22:44 For year two, we didn't make money. So,
22:46 we're going to jump and pass to year
22:50 three where we are making 6,000.
22:54 And we can reinvest it at same 6%
22:58 however only for 2 years.
23:01 So, if we calculate that 1.06 raised to
23:03 power 2
23:06 * 6,000
23:10 that gives us 6,741.6
23:14 six year four and year five. For year
23:17 five, remember this 10,000 we don't have
23:20 time to reinvest it because it's just
23:23 coming at the end. So that remains the
23:25 stamina value.
23:29 Easy 10,000 just like we did before. But
23:32 for year four, we have 7,600
23:36 that we can still reinvest
23:39 but only for one year. So that means we
23:44 have 1.06 * 7,600
23:47 and that gives 8,56.
23:51 So which means the total terminal value
23:54 of all our inflows is addition of all of
23:58 this. So I'm going to add that together.
24:09 that gives 29 847.5.
24:16 So which means we have the terminal value
24:18 value
24:22 of our inflows.
24:24 And once we have that then we can go
24:29 back to our formula that says that MR
24:31 is equals to terminal value of all the
24:35 inflows 29847
24:38 divide by the present value of outflow
24:52 and rais^ 1 / 5 - 1 so if I divide that
24:56 by 21 684
24:58 I have 1.376
25:02 raised to power 1 5
25:05 that gives 1.0
25:10 666 then -1 that goes to 0.066
25:19 That is MR for that question. Even if
25:22 you put it on Excel, like I said, I will
25:24 show you on Excel how to do it quickly.
25:26 So, just like I promised, I was going to
25:29 also show you how you can do this so
25:31 easily on Excel. Yeah, you can have it
25:34 in exam as well. So, you can compute on
25:36 Excel. So, you need to know how to do it
25:38 both manually and on Excel. So, you want
25:40 to do this on Excel, all you need to do
25:43 is to start with equals to. Remember any
25:45 formula on Excel needs to start with
25:48 equals to then you just put MR right
25:50 right
25:53 is already coming up but even if it's
25:56 not coming up type M then open a bracket
25:59 then highlight all the values that you
26:01 are trying to work with all the cash
26:04 flows all of them and you put a comma
26:07 then you put the finance rate for this
26:09 particular question remember we said we
26:11 will assume that the finance rate and
26:13 investment rate are similar. So this
26:16 finance rate now we put 8%.
26:19 And likewise the reinvestment rate we
26:23 put 8%. Close the bracket. Enter. Then
26:26 you have 11%. Remember when we did it as
26:29 well we had 11%. And that is for that
26:30 question the first question. The second
26:32 question as well these are the cash
26:34 flows that we plotted. We have the
26:37 investment rate at 6% financing rate at
26:41 9%. So if we use the same formula equals
26:48 same one I like all the cash flows
26:50 comma the first one is the financing
26:54 rate which is 9% comma reinvestment rate
26:58 then if you enter you have the MR in
27:01 percentage and that is it you can see 6.6%.
27:02 6.6%.
27:04 Which was exactly the same thing we got
27:08 when we did it manually. So that is MR
27:10 for you. Even IR you can also calculate
27:13 on Excel in case you are wondering if
27:16 it's possible. Yes, the same way
27:20 IR then I like all of this. So for this
27:22 particular investment that is your IR
27:24 for that investment. The same thing you
27:29 can do for this guy too. So this is MR
27:32 want to get the IR can also use the same
27:35 formula. Yeah. So everything that you
27:38 can calculate manually can calculate on
27:41 Excel. That is it. If you have any
27:43 question remember to always bring it up
27:45 and hope this is clear. So we're going
27:49 to move into the last part of this
27:52 measurement which is duration. Remember
27:56 for NPV IRRa and discounted payback
27:58 method I've referred you to my earlier
28:00 videos on FM. It's the same
28:02 understanding that you need to have.
