From the lesson

Semana 2

En este módulo, concluiremos el tema del Valor Tiempo del Dinero con un debate sobre la inflación antes de avanzar al segundo tema, Tipo de Interés, y presentar nuestro tercer tema, Análisis de Flujo de Fondos Descontados. Al final de este módulo, te sentirás cómodo descontando y componiendo flujos de efectivo arbitrarios para valorar diferentes reclamaciones y tomar mejores decisiones financieras.

Finance

Welcome back to Corporate Finance.

This time we're going to turn to a new topic, Discounted Cash Flow Analysis.

But before doing so, I want to briefly recap our last topic, Interest Rates.

We started off discussing interest rate quotes and

how they differed from the interest rates we used to discount cash flows.

We then discussed how to discount cash flow streams when the cash flows arrive

at frequencies other than annual and

when the compounding of interest was something other than annual as well.

We closed off the topic by discussing the term structure of interest rates and

the yield curve, both of which summarize the relationship

between interest rates and the term of the investment.

Today we turn to discounted cash flow analysis.

And I want to start the topic off by discussing how firms, or

people more generally, should be making decisions.

Let's get started.

Hey everybody, welcome back to corporate finance.

Today we're going to be shifting gears to a new topic,

Discounted Cash Flow Analysis.

But before doing so I want to briefly recap our last topic, interest rates.

So in that topic we started off by introducing the notion of APR and EAR,

and a periodic discount rate.

The difference being as follows, right?

APRs or Annual Percentage Rates are a means to quote interest rates.

Whereas EAR, Effective Annual Rate, and

the periodic interest rate are actually discount rates.

They're economically relevant, they're what we care about,

they're what we use to discount cash flows and make decisions.

Then we use those discount rates to value and

assess cash flow streams that were no longer arriving on an annual basis,

and the deal with the compounding of interest on a non-annual basis.

Then we closed off the topic of the discussion of the term structure of

interest rates, which is the relation between the interest rate and

the term of the investment or the duration of the investment.

And we discussed yield curves, mostly how to construct them, what the yield means,

where it comes from, and how to interpret these graphs.

Now we're going to switch over to discounted cash flow analysis and

I want to start by motivating the topic and

providing a little bit of background by discussing decision making.

So let's get started.

Let's start with a question.

How should we make financial decisions?

Well, a reasonable answer might be to undertake those actions that create value.

Value for those affected by the decision,

value for the owners of a firm for example.

Which actions create value?

And while that's a complicated question, a sort of general answer that seems

reasonable would be to consider actions in which the benefits exceed the costs.

But here's a little wrinkle, what if the costs and

benefits arrive at different times?

Well actually, we're well equipped to deal with that wrinkle because we can compare

the present value of the benefits to the present value of the costs.

See, because by computing the present value we know that the discount rate,

R, will adjust both for the timing and the risk of the cash flows.

So that brings us to our first lesson, which is

that the NPV Decision Rule, that is NPV which stands for

Net Present Value.

NPV.

The NPV decision rule says that we should accept all projects with

a positive NPV and reject all projects with a negative NPV.

Where NPV is nothing more than the difference between the present value of

the benefits and the present value of the cost.

In other words, if the present value of the benefits is

bigger than the present value of the cost, that's a good thing, that creates value.

And we want to undertake that project, or

make that decision that leads to positive NPV.

And while this formula right here looks somewhat vague and

ambiguous, it's actually masking something that we're all ready very familiar with,

and that's just discounted cash flows.

NPV is nothing more than discounted cash flows,

except now instead of cash flow CF, I have this F in front of all the cash flows.

So it's FCF.

The F simply stands for free.

So these are free cash flows, but they're still just cash flows nonetheless.

There's nothing special there.

I'm going to formally define and discuss how to compute free cash flows in our

next lecture, but for the time being just recognize we're doing nothing new here.

We're simply taking a stream of cash flows,

FCF naught, FCF 1 through FCF T, and we're discounting them back to today,

by a discount rate R, to get a present value, a net present value.

That's it.

And so the decision rule just says if the NPV is greater than 0, accept the project.

If the NPV is less than 0, reject the project.

Sorry, reject the project.

And while that seems fairly easy and

straightforward, actually implementing it is quite a bit more subtle.

And we're going to talk about those subtleties as we move along,

throughout this topic.

So, before moving on to some of the mechanics of a DCF analysis,

I want to talk about decision making in practice briefly.

Because it's useful to motivate it and to understand what people

in different areas of both finance and

non-financial sectors are doing when they're making decisions.

So the first thing I want to look at is this, or show you,

is this survey evidence from a survey by John Graham and Cam Harvey,

former colleagues at Duke, in which they surveyed CFOs from

the Fortune 500 and other US domestic firms.

And they asked them, how frequently do you use capital budgeting,

different capital budgeting techniques.

And what you can see is that there are actually a variety of responses.

I've listed six here.

But the majority or the predominant number of responses point to

net present value and internal rate of return as the most popular

decision criteria that CFOs use.

That's followed somewhat closely by the payback rule, and

to a lesser extent, the discounted payback rule.

In our discussion of DCF, while NPV is going to be center stage, we're actually

going to spend a fair amount of time discussing all of these decision rules.

Because each one actually has important information for the decision making

process, though each one also has certain limitations that we need to understand.

Now that's in the non-financial corporate sector.

If we look at what investment bankers do when they are valuing

companies in fairness opinions, you can see that the large majority of investment

bankers are also relying on discounted cash flow analysis, something akin to NPV.

But they're also using a host of comparables methods or

relying on multiples.

And while this is going to take us a little bit outside of the scope

of our course I might mention, if we have some time,

how we use multiples in valuation exercises.

If not, I might post some additional material.

And finally, there's a recent survey by Paul Gompers, Steve Kaplan,

and Vladimir Mukharlyamov.

I hope I'm not butchering that name too poorly.

But they have a really interesting survey of private equity

firms in which they investigate, among many things,

which criterion PE investors used to evaluate an investment.

And what's interesting here is the vast majority rely on internal

rate of return, by a wide margin, over any other criterion.

So let's summarize this.

So we're going to move through this topic of DCF, discounted cash flow,

emphasizing to a certain extent the NPV rule, because that is the optimal

rule in terms of always leading you to making the decision that creates value.

That said, I'm going to take a much more practical perspective

to corporate decision making, or financial decision making more broadly, and

recognize that other rules are still informative.

They're still useful.

So it's not surprising that we see their use by practitioners, whether it's PE,

private equity investors, or investment bankers, or CFOs.

They're still informative, but the important thing to keep in mind is that

these other rules have certain weaknesses that we need to understand and

we need to recognize the limitations of these rules so

that we can use multiple rules in conjunction to come to the best decision.

So what's next?

We're going to dive into how to compute free cash flows,

the first stage in understanding how to execute a DCF.

So, I look forward to seeing you in the next lecture.

Thanks so much.
