Principles of finance ah la shmoop discounted cash flow analysis

00:05

Okay this whole thing is a big fat example Time

00:09

Yes whale of a tale Our company produces cash flow

00:13

today and we bet it will produce it in the

00:15

future But in our future there is uncertainty mainly as

00:20

it relates to the amount of cash that will you

00:24

know flow and the risk that the number we're guessing

00:27

will flow will be higher lower or the same like

00:29

there's risk we don't know what the number is going

00:31

to be All of this is mapped against the background

00:33

of what a safe investment e a u s treasury

00:37

bill would produce with high levels of certainty in that

00:39

same period And that treasury bill return has already adjusted

00:43

for the gumball experiment in everyone's gases toe what inflation

00:47

will be So the treasury bill is a base case

00:49

important element in the math of dcf models what's kind

00:52

of two things really it's a safety of payment thing

00:56

and it's also inflation adjusted all in that won t

00:59

bill number but okay dcf modeling is the big kahuna

01:02

of financial valuation tools is largely what the pros used

01:06

To attach a given value to a company we're gonna

01:08

walk you through the nitty and the gritty of how

01:10

you do a fully ugly dcf model in warning this

01:14

will hurt but you won't die from trying it Well

01:16

we're focused here on money we expect in the future

01:19

but discounted back for time and risk got it it's

01:22

key elements dcf model We're gonna work through an example

01:24

with cash flows but you can imagine this system applying

01:27

to the value of stocks or bonds or lottery tickets

01:30

or a random celestial events And most importantly for this

01:34

set dead end or dying rich relatives Yeah all carry

01:37

the structure of time and risk discounting such that they

01:41

could be plugged into a dcf model And yes uncle

01:44

larry as this applies to you too you will die

01:46

in a few years or in twenty and by then

01:49

you'll have what a million bucks twenty one hundred And

01:52

what will inflation make that one hundred million dollars in

01:54

twenty years worth today All right it's time and risk

01:57

All right we're moving on crystal balls Yes You feel

02:00

pity for the young male crystals who had to die

02:03

Or worse to donate them for this project Uncle larry

02:06

phones you at three In the morning You barely make

02:08

out his words But you know he had a drug

02:10

problem for a long time Brilliant man but you know

02:13

fried his brain Well a week later you learn he's

02:15

dead his lawyer Honest How sends you a registered letter

02:19

informing you that you'll be receiving one million dollars in

02:22

a year That's a million bucks We have the flow

02:25

of cash now and we have pretty high certainty of

02:27

a payout Like we trust how we know him He

02:29

didn't joke around How also in tones that your other

02:32

uncles moe and curly are ill A swell Hey sir

02:36

Minds is that each will die in subsequent years and

02:39

each will leave you one million dollars And then the

02:42

lawyer tells you that your grand daddy warbucks was going

02:45

to leave his fortune toe larry moe and or curly

02:48

But that if none of them are alive well you

02:50

get all fifty million dollars of his estate and it

02:54

looks like granddaddy has at least two years left in

02:56

him So your crystal ball comes out It says that

02:58

Your best guess as to the amount and timing of

03:01

your cash flows Looks like this are so t plus

03:03

one it's one year today's million bucks and people too

03:06

likely curley dies You get a million there and in

03:08

three years mode eyes and won't say in four years

03:11

we're guessing on daddy warbucks after they're all dead Then

03:14

you get that fifty All right but you need to

03:16

have a present value for all fifty three million dollars

03:20

that's involved here Meaning you want to go to a

03:23

bank It's called a fact door and pledge that money

03:26

over to them getting cash today for that future dough

03:29

So that right away you can go live your life

03:32

have fun enjoy things and get that place in malibu

03:35

with the entryway water slides All right Well you need

03:37

to discount back those future flows of cash to today's

03:41

value so that you can negotiate with the bank to

03:44

sell them those flows and get your cash today So

03:47

then how do you discount that flow of dough back

03:50

to today While the formula runs like this start with

03:52

the risk free rate That's those t bills we mentioned

03:55

And their brethren good government bonds and t notes and

03:59

so on And you look through the bond quotes online

04:01

and you know it that well today u s government

04:03

paper coming do exactly in one year yields one point

04:06

five percent and get that anywhere online and quotes for

04:09

free and then government paper in two years That's when

04:12

the next guy dies yeah that's two percent government in

04:15

three years you have the next guy dies Well that's

04:17

two and a half there and government paper coming due

04:19

in four years When you expect daddy warbucks to die

04:22

and leave you all fifty paper today you could buy

04:24

and get three percent per year yield That tells you

04:27

that we're living in a normal yield curve environment and

04:30

the market is likely pricing in modest inflation and maybe

04:34

a fed rate hike that's modest into the future Well

04:37

the market has thus done a whole lot of the

04:39

homework for you already In pricing of these otherwise crazy

04:42

complex issues in calculation inflation and risk adjusted returns into

04:47

the future In addition to that risk free rate Well

04:50

we have tto add that curly moe in Well gee

04:53

Dw don't die at least they don't die on time

04:56

Or maybe yeah you're not really their sole heir That

04:59

is there's risk involved in receiving the cash flows beyond

05:03

just the risk of the us government defaulting on its

05:05

promises payday loans and so on Well how do we

05:08

matthew lee at tribute numbers too quantify that risk and

05:12

it's not just risk of malaria in curly not dying

05:16

but it's other risk like some other aer materializes and

05:19

lays claim to the money or the estate in the

05:21

inheritance laws change after the socialist candidate gets elected from

05:25

california and caps inheritance amounts at a million bucks after

05:29

that Well the government then keeps everything what They have

05:31

a lot of pensions to pay so there's risk there

05:34

How do we quantify it While there's a donkey and

05:36

a tail in a fifty shades brand blindfold leftover from

05:40

the party last night Right We'll each risk has to

05:42

be individually assessed So let's review larry is already dead

05:46

The lawyer called and told you in writing that you

05:48

are the sole heir and you definitely get a million

05:51

dollars no matter what there's almost no risk here so

05:54

you just have to have the time value of your

05:56

money which you equate to u s government bonds certainty

05:59

death and taxes So you're going to safely discount back

06:03

that million dollars from uncle larry police is a state

06:06

at the rate of one point five percent adding no

06:09

risk premium to it You're just going to get government

06:12

t bill rates and that flow to you is valued

06:14

as a million dollars divided by the quantity one plus

06:17

zero point one five to the first power because it's

06:20

just one year away that sometimes he iterated just one

06:23

And that equals about nine hundred eighty five grand So

06:25

if someone offered you that amount to buy you out

06:28

of the inheritance from larry well you'd in theory be

06:31

neutral but likely take the cash because you know a

06:33

bird in the hand and it's likely that the ferrari

06:36

and the window is tickling you the cash out right

06:39

Well under the second cash flow we have to discount

06:41

uncle curly You stand to inherit a million bucks from

06:43

curly but not for two years and minor detail He's

06:46

not dead yet and there is risk he doesn't die

06:50

At least not any time soon where all the banana

06:53

peels laying around should be there Well there's risk he

06:55

doesn't name you soul oeiras Well by the way and

06:58

there's risk that it turns out he owed other people

07:00

a ton of money and that the two million he

07:02

said he was giving you was really two million yen

07:05

not dollars And on and on and on tons of

07:07

other risk including the one where he donates his money

07:11

to the society of booboo which you know he's a

07:14

big fan of So in this case you attribute a

07:16

very high risk like twenty five percent per year calm

07:20

pounded that this whole inheritance thing with him doesn't happen

07:23

But how do you calculate that flow of a projected

07:25

guest at two million dollars in two years Well you'd

07:28

receive a million dollars in two years and the two

07:32

year government paper rate is two percent Plug in the

07:35

same formula you just did for larry and you get

07:38

a million dollars divided by one plus the quantity of

07:41

the risk free rate of two percent or point zero

07:43

two plus the risk premium to the second power let's

07:47

Take the Numbers 1 by 1 here You know where

07:48

the million came from That's The inheritance amount with one

07:52

in there is because we're dividing by a number greater

07:54

than one to discount back the future amount Then we

07:57

have the point o two thing there which is the

07:58

risk free government paper rate That's what it's currently yielding

08:02

Then we have to add the risk premium point two

08:05

five or twenty five percent per year to get a

08:07

total of point two seven as the total risk free

08:10

plus risk adjusted discount rate against that million bucks two

08:14

years from now And the to the second power thing

08:18

right there exists because the event is to compounded years

08:22

away Iterated twice So the summary formula for this one

08:26

is a million over one point two seven to the

08:29

second power or a million over one point six one

08:32

two nine for about six hundred fourteen grand So let's

08:35

think about that for this event your neutral substitution point

08:39

or value in taking cash today versus waiting two years

08:43

teo hope to get that million bucks is a bit

08:45

more than half the eventual amount That's a lot of

08:48

discounting there but it makes sense because the death of

08:51

your dear uncle isn't certain and neither is the notion

08:54

that you'll receive all the dough when he does finally

08:57

bucket kick or that there will even be doa at

09:00

that point to give you in fact the twenty five

09:02

percent number well maybe way optimistic and whatever it should

09:06

be called given that we're in the business of betting

09:08

on death here it's like a life insurance company we're

09:11

gonna move on to the third cash flow Mo is

09:13

sick luckily financially for you he liked the whoopee cushions

09:17

from around the world You sent him each year on

09:20

his birthday So he's already told you and his lawyer

09:23

and everyone else that you are his sole heir He

09:26

put it in writing certified it and he's tired of

09:28

suffering So he's also left instructions that if he's in

09:31

an iron lung three years from now the union nurse

09:34

should pull the plug and let him go off to

09:37

the big stooge in the sky in relative peace So

09:40

your discount rate for the mo money is way lower

09:43

than for the curly money That is the risk premium

09:47

You'll add to the risk free rate here is way

09:49

less And you think about that risk is being just

09:51

five percent Why not zero risk premium Well because there's

09:55

always curveballs in life and you can't predict him and

09:58

you want to be conservative in you're discounting So then

10:00

the cash flows looked like this eventual money A million

10:03

box risk free rate two point five percent that's for

10:06

the government treasury paper coming due in three years at

10:09

current market prices and the risk premium there's just five

10:11

percent The duration is three years or three iterations So

10:15

the formula then looks like this We have a million

10:17

over the quantity One plus the quantity point o two

10:21

five plus point Oh five All to the third power

10:23

there All right well simplifying We get a million over

10:26

one point Oh seven five to the third and again

10:29

that's a million over one point two four ish So

10:32

the president value of your million box in three years

10:35

in this case is eight hundred six grand And this

10:38

is kind of interesting for dcf geeks Anyway this money

10:41

which comes three years from now has ah higher present

10:45

Value than the curly money which comes only two years

10:48

from now Why risk way less risk way higher present

10:53

value Last calculation for this problem Grand daddy warbucks you

10:58

know that gee dw is likely to name you sole

11:01

heir And every actuarial table you've read shows him dying

11:04

in exactly four years That's the over under number Every

11:07

term life insurer uses So what do you know You

11:10

use it too He could die in four years Or

11:12

ten or twenty Hi Standard deviation Yeah You know you

11:15

know he wants you to have the money So without

11:18

a lot to go on while you just apply a

11:20

ten percent risk premium to the risk free number two

11:23

do you're discounting here and you get the numbers Here

11:26

we go Terminal value Fifty million dollars government risk free

11:29

rate for guaranteed payment for years from now three percent

11:32

a year Compound it risk premium here's ten percent years

11:35

to event for and the formula then it's for fifty

11:37

million over the quantity One plus the quantity point Oh

11:39

three plus point one all to the fourth power which

11:42

is the same as fifty million over one point one

11:45

Three to the fourth which equals fifty million over one

11:47

point six three for about thirty point seven million box

11:50

ish the present value of your getting fifty million box

11:54

from g w four years from now discounted back for

11:57

risk in times about thirty million dollars that is fifty

12:00

million dollars in four years with risk adjusted in this

12:03

case today you're estimating is worth thirty mil So then

12:07

what is your total value of your family financially speaking

12:12

Of course well we'll just adam up larry gave you

12:14

a nine eighty five k discounted back curly with six

12:17

fourteen mo was eight o six and g g w

12:21

was thirty point seven million there All right so we've

12:23

discounted the cash flows Now all we have to do

12:25

is adam up and they add up like this and

12:27

they come to in about thirty three million and change

12:30

and note that the terminal payment of that discounted fifteen

12:33

million well it dwarfs the other flows at least a

12:36

this point So this is a structure you'll see a

12:38

lot when you're valuing payout of bonds and more commonly

12:41

stocks or equity investments that eventually gets sold that is

12:45

An equity investment will produce cash for three or four

12:48

or five or more years and then it will get

12:51

sold for twenty times earnings or whatever that eventual multiple

12:54

is and you'll discount it back for time and risk

12:57

and that eventual sales price probably carries the most risk

13:01

or at least aton of risk so it'll carry a

13:03

big discount value and it's usually calculated a decade or

13:07

so out so you think about the time value decreasing

13:10

a lot of that sum to today's values Note also

13:14

that we've used imprecise numbers here Why Because precision is

13:18

a joke when it comes to dcf models our own

13:20

got assessment of the risk of adventure has a lot

13:23

more to do with the eventual outcome than getting the

13:26

third decimal correct so don't do it It makes you

13:28

look like you don't understand that a whole lot of

13:30

guessing is involved here And unfortunately for you however well

13:34

moe curly and g w just signed up his trial

13:38

subjects for elon musk snu eternal life company so well 00:13:42.739 --> [endTime] let's Just hope you kept your receipts No
