# Investment Appraisal Discounted Cash Flow – NPV

## Introduction to Discounted Cash Flow – NPV

In this lecture we will be looking at how the Financial Manager should go about making capital investment decisions. For example, they may have to decide whether or not it is worthwhile investing \$1,000,000 in a new factory. Alternatively they may have to make the choice between several available investments.

## Discounted Cash Flow – Net Present Value

This approach looks at the expected cash flows from the investment in question. If over the life of the investment there is an expected cash surplus, then the project will be accepted, whereas if an expected cash deficit the project will be rejected.
To account for the fact that money will be tied up in the project over a period of years (and will therefore either result in interest being paid on money borrowed for the investment, or interest lost on the money invested), the cash flows are discounted at the cost of money (or cost of capital) to the company before calculating the net surplus or deficit and making the decision.

Hello all including John,

I am having trouble calculating the inflated variable and fixed cost in the NPV question in June 2011.

Any help will be appreciated

You must ask this sort of question in the Ask the Tutor Forum – not as a comment on a lecture.

Mr. Moffat please i have got a question on your example of investment appraisal/discounting. I’m struggling a little bit in digesting the concept of COST OF CAPITAL.

You gave an example of an initial outlay of US\$50,000 and the future cash flow in two years is US\$60,000. I’ll use your subsequent lecture on dividends to interpret this…..If i expect a cashflow of US\$60,000 and require a return of 10% in two years then the present value or what i am willing to pay today is US\$49,587(I understand that clearly).

Then does COST OF CAPITAL (discount rate) mean that my cost is US\$50,000, but should have been US\$49,587? So I’m losing US\$413? So in other words I paid US\$50,000 to get US\$60,000 in the future instead of paying US\$49,587, thus I’m US\$413 poorer?

I understand the term when you call it the rate of return as in the dividend example, but I’m struggling to understand the term when you call it a discount rate. Would really appreciate it if you could explain.

• says

What you write is correct.
If we require a return of 10% then either we need to get more than 60000 from our investment of 50000, or alternatively we would only be prepared to invest a maximum of 49587 to get the return of 60000.
If we did choose to invest 50000 and get 60000 back, then we would effectively be losing 413, and so we would prefer not to invest.

There is nothing magical about the word discount. Discounting is simply the word we give to working out the equivalent amount now of a future cash flow. We can call the interest rate we use to do the discounting the discount rate.

Hello, I can see that the below has been deleted from the syllabus, however it is not quite clear for me. Do we not have to calculate the present values of cash flows (using figures from the tables) for the Dec 2013 sitting?

a) Explain and apply concepts relating to interest
and discounting, including: [2]
i) the relationship between interest rates and
inflation, and between real and nominal
interest rates
ii) the calculation of future values and the
application of the annuity formula
iii) the calculation of present values, including
the present value of an annuity and
perpetuity, and the use of discount and
annuity tables
iv) the time value of money and the role of cost
of capital in appraising investments

• says

It is all assumed knowledge from Paper F2, and everything is still examinable (and is examined – the syllabus changed at the beginning of 2013 and all the above was examined in June 2013)

• says

thank you, thought it iwas no more examinable.

4. says

i am still slightly confused as to why he did 60,000 divided by (1.1)^2 to get £49,587? – I fail to understand the concept regarding this, can anyone reword it berrer? thanks.

• says

Discounted cash flow is assumed knowledge from Paper F2, so for a fuller explanation have a look at the relevant Paper F2 lectures on here.

5. says

Brilliant! Well explained lecturers. Thank you so much OT for making my life easy.

Alresford Ltd is considering the purchase of 100 per cent of the ordinary shares of the all
equity-financed Gibson Ltd. Gibson operates in two divisions – North and South – and a head
office. The divisions operate independently of each other; the only joint costs of Gibson, not
attributable directly to either division, are those of the head office. Gibson’s management is
currently committed to operating both divisions for 4 years and have estimated operating
cash flows and the taxable operating profits of each division as:

Operating Cash Flows Taxable Operating Profits
Division Division
Year North (\$000) South (\$000) North (\$000) South (\$000)
1 12,000 12,000 8,000 12,000
2 12,000 8,000 12,000 8,000
3 16,000 8,000 16,000 8,000
4 20,000 4,000 24,000 4,000

The above figures exclude:

1. Head office costs of \$ 4,000,000 per year.

2. Planned capital expenditure by North division in year 1 of \$ 8 million and its tax
consequences. The capital expenditure is necessary for North division’s continued
operations and the above figures assume it will be undertaken.

3. The salvage values of Gibson’s assets. Salvage values will be received at the end of year
4 and are estimated at

North division \$ 24 million
South division \$ 12 million

Equipment used at head office is all rented on short-term operating leases and
therefore has no salvage value to Gibson at any time.

The above details are widely known and would continue to apply to Gibson after any
takeover, except that

1. Some of Gibson’s administrative activities would be undertaken by Alresford, resulting
in savings of head office costs of 50% in years 1 and 2 and 75% in years 3 and 4.
2. At year 4, North division’s assets would be used by Alresford to substitute for capital
expenditure of \$ 28 million planned for year 4.

Alresford’s Director of Strategic Planning has suggested that if a takeover is completed then
various options are available to Alresford. She has detailed the options, but has made no
attempt to appraise their financial desirability. The details are:

1. Early termination of South division’s operations. This would change the estimated
salvage values which would be realized immediately on termination of the division’s
activities. Early termination would also enable operating cash flows, and taxable
profits, to be increased by a constant amount for each year of the division’s revised
life, the level of the constant increase being dependent upon the date of termination.
The revised figures are:

Operations terminated at
end of year
South division
Revised salvage value
2 \$ 20 million \$ 4 million
3 \$ 16 million \$ 3 million
Increase in annual cash
flows for each year until
termination

2. Alresford’s own transport department could be used to carry out North division’s
deliveries, thereby saving the division \$ 600,000 per year in transport costs. However,
this policy would cause Alresford’s transport department to modify its planned
replacement cycle, and expenditure of \$ 1.6 million, scheduled for both year 3 and 5,
would be increased to \$ 2 million and would occur earlier, in year 1 and year 4.
Thereafter all planned replacements would be unchanged.

3. By incurring additional advertising of \$ 3.6 million in year 1, sales of North division
would increase producing additional profit, and cash flow, of \$ 2.4 million for each of
years 3 and 4.

Alresford’s Financial Director believes that an appropriate risk-adjusted after-tax discount
rate to be applied to all cashflows relating to the consequences of the proposed acquisition
is 18%.

The corporate tax rate is 30%, with taxes payable in the year that taxable profits arise.
Alresford Ltd. has exclusively overseas resident shareholders, and so is not integrated into
the dividend imputation system. To stimulate the economy, the government has recently
announced that all capital expenditure may now be fully depreciated at the time it is made
for tax purposes (so that capital expenditure can be treated as an allowable expense in this
question). All sales of assets will be subject to taxation. Assume all cash flows occur on the
last day in each year.

Part A of the Assignment (12 marks):

Clearly state any assumptions you make and explain all calculations in full. Use an 18% aftertax
cost
of
capital.

(a) Estimate the market value of Gibson Ltd in the absence of any take-over possibilities.
(4 marks)

(b) Advise Alresford Ltd. on the maximum amount it should be prepared to pay for Gibson
if the Strategic Planning Manager’s suggestions are completely ignored.
(4 marks)

(c) Determine which of the Strategic Planning Manager’s suggestions should be
undertaken and specify the optimum life of South division. Advise Alresford Ltd. of the
maximum amount it should now be prepared to pay for Gibson.
(4 marks)

Why have you typed out an entire question?

Surely you do not expect us to provide an entire answer?!

If you have specific problems (after having watched the relevant lectures) then by all means post them in the Ask the Tutor forum, and we will try and help.

• says

Can you help me to find the IRR

• says

I am not sure why you want the IRR since it is not asked for!

However since you have presumably calculated the NPV at 18%, you need to guess a second discount rate and calculate the NPV at that rate also.
Then interpolate/approximate between the two as per my lecture.

• says

I am going beyond the rate of 100% and still not getting a negative NPV. Could help me please

• says

I can only think that you have got your cash flows wrong (and I am still puzzled about why you want the IRR )
