The NPV Investment Evaluation Process
Step 1 - Calculate depreciation
Step 2 - Calculate any gain/loss on disposal
Step 3 - Calculate taxable income, i.e. profit or loss
Step 4 – Calculate the tax item, i.e tax bill or rebate
Step 5 - Calculate net cash flows
Step 6 - Discount the net cash flows
Step 7 – Conclusion – NPV: + accept, - reject

Example
Purchase price $42 000 Salvage value $1 000 at end Year 3 Operating net cash-inflows Year 1 $31 000
Year 2 $29 000 Year 3 $27 000
Feasibility study cost $4 000 – yet to be paid Warehouse previously rented out for $8,000 p.a. will be used for
project New technician will replace existing technician. Existing technician’s salary = $65 000 p.a. New technician’s salary = $70 000 p.a. Old machine can be sold for $2500, book value is $3 000 Tax rate is 30% Depreciation is straight line Required rate of return is 12% p.a.

Solution – depreciation and gain/loss on disposal
Depreciation = cost price/no. of years
= $42,000/3 = $14,000 p.a.
Gain/loss on sale:
Old Machine New Machine
Book value yr 0 3000 Book value yr 3 0
Salvage value yr 0 2500 Salvage value yr 3 1000
Loss on sale 500 Gain on sale 1000
Note: book value = cost price less accumulated depreciation

Finance costs
Finance costs should not be included as an explicit cash flow in the analysis.
Finance costs:
cost of debt (interest expense),
cost of equity (dividends)
Finance costs are included in the required rate of return (discount rate) used to evaluate the project.
![Page 9: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/9.jpg)
Incremental Cash-Flow Example
In NPV analysis we are only interested in incremental cash-flows.
Example: A firm is currently considering replacing a machine purchased 2 years ago with an original estimated useful life of 5 years. The replacement machine has an economic life of 3 years.
![Page 10: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/10.jpg)
Solution – depreciation and gain/loss on disposal
Depreciation: old machine = $48,000 p.a.,new machine = $120,000 p.a.
Gain/loss on sale:Old Machine New Machine
Book value yr 0 144,000* Book value yr 0

One Step Process
•Rather than adopt a two step process to Project Evaluation (i.e. P & L Statement and Cash-Flow Statement) a one step process can be undertaken (Cash-Flow Statement only).
•Rather than work out taxable income (profit or loss) and tax in step 1 (P & L Statement) and cash flows in step 2 (Cash-Flow Statement) one can directly work out after tax cash flows for each item (in the Cash-Flow Statement).
•We will go on to illustrate by doing the second worked example just undertaken in one step
![Page 16: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/16.jpg)
Relevant Cash Flows
One-Step Process Revenue::
cash inflow due to sale of goods and services revenue is taxable, therefore net cash-inflow after-tax equals:
REV - (REV * (tREV - (REV * (tcc)) )) oror REV (1 - t REV (1 - tcc))
where twhere tcc = corporate tax-rate = corporate tax-rate
Expenses:cash outflow due to expenditures of production, etcexpenses represent a tax saving (they are tax deductible,
therefore they reduce tax payable (they provide a tax-shield))net cash-outflow after-tax equals: EXP – (EXP * tEXP – (EXP * tcc ) ) oror EXP * ( 1 - t EXP * ( 1 - tcc))
![Page 17: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/17.jpg)
Non-Cash Flow Items
Depreciation Tax Shield
Depreciation is a non-cash expense that is an allowable tax deduction (it provides a tax-shield). Thus it reduces the tax payable by:
Depreciation * (tc)Depreciation * (tc)
This represents a cash inflow (a tax rebate).cash inflow (a tax rebate).

Book Gain/Loss on DisposalBook Gain/Loss on Disposal• salvage value (SV) = sale price (market value) received on disposal of asset
• asset has a book value (BV) = purchase price less accumulated depreciation
if SV > BV we have a book gain
– a taxable profit arisesTax on profit = book gain * tc
This leads to a tax liability (a cash-outflow)
– The net after-tax cash-inflow from disposal will be:
SVSV lessless ((book gain * tc)
if SV < BV we have a book loss
- a deductible loss arises Tax saving on loss = book loss * tc
This leads to a tax rebate (a cash-inflow)
– The net after-tax cash-inflow from disposal will be:
SV plusplus (book loss * tc)

Evaluating Projects with Different Lives
If two projects are mutually exclusive they are competing projects
A choice between the projects must be made
Evaluation of the projects is complicated if they differ in life span i.e. are each over a different number of years
A common base is required for comparison
![Page 21: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/21.jpg)
Evaluating Projects with Different Lives
Two methods of evaluating projects with different livespans:
Equivalent Annual Annuity
Approach (EAA)
2.2.
Lowest Common Life Approach
(LCL)
1.1.
![Page 22: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/22.jpg)
Lowest Common Life Approach
Involves choosing the lowest common multiple of lives
NPV of each project is calculated assuming each is replaced with itself until the lowest common multiple life is reached:
e.g.e.g. Project A has a life of Project A has a life of 99 years yearsProject B has a life of Project B has a life of 1111 years yearsTherefore LCL = 9 x 11 years = 99 yearsTherefore LCL = 9 x 11 years = 99 years
Replace Replace Project A Project A 11 times11 times with another project of an with another project of an identical identical cash flow patterncash flow pattern
Replace Replace Project Project BB 9 times9 times with another project of an with another project of an identical identical cash flow pattern.cash flow pattern.
Computations can become tedious (in this example over 99 years!!!)
![Page 23: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/23.jpg)

LCL Approach – Constant Chain of Replacement Assumption
Implicit assumption with LCL approach is that asset will be replaced continually by itself, and that technology, operating efficiency, sales and costs do not change.
This is supported by: The importance of cash flows further into the future
decreases (time value of money concept), and Cash flows forecasted for the life of an asset are as good as
any other forecast of cash flows (i.e. management’s forecast of cash-flows will be more accurate than any other’s)
![Page 25: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/25.jpg)
Equivalent Annual Annuities (EAA)
When comparing two mutually exclusive projects with different lifespans it is necessary to make comparisons over the same time period.
EAA compares each project’s cash-flows calculated on an annual basis.
We select the project with the highest EAA if the cash-flows are positive
We select the project with the lowest Equivalent Annual Cost (EAC) if the cash-flows are based on costs (i.e. cash-outflows)
![Page 26: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/26.jpg)
Equivalent annual annuity
To calculate the equivalent annual annuity (EAA):
1.1. Calculate NPV of each project over one life - as if it were Calculate NPV of each project over one life - as if it were "one-off""one-off"
2.2. Convert the NPV into an equivalent annuity for the life of Convert the NPV into an equivalent annuity for the life of each project - convert into a series of annual payments or each project - convert into a series of annual payments or annuity payments annuity payments
(i.e find the unknown PMT for the project using the PV of an (i.e find the unknown PMT for the project using the PV of an ordinary annuity formula)ordinary annuity formula)

We assume each project can be replaced an infinite number of times in the future, and then convert each NPV to its equivalent annuity
The projects’ EAAs can be compared to determine which is the best project

Capital Budgeting And Inflation
In project evaluation not adjusting for inflation may result in material errors in capital budgeting decisions.
Inflation is included implicitly in the discount rate
Nominal interest rate = [(1+ real interest rate)(1+Inflation rate)] – 1
This is known as the Fisher EquationExample:expected inflation rate = 4.72%, real interest rate = 6% nominal interest rate = [(1+0.06)(1+0.0472)] – 1 = 0.1100
= 11.00%
![Page 34: Topic 4 Capital Budgeting Part 2](https://reader036.vdocuments.net/reader036/viewer/2022062322/55cf9aa6550346d033a2bc09/html5/thumbnails/34.jpg)
Depreciation And Inflation
Inflation erodes the real value of any depreciation tax deduction and therefore discourages capital investment in an inflationary period.
The further into the future is the depreciation claim the lower is its real present value (time value of money concept).
If we assume no real rate of interest we can work out at varying inflation rates the present value of the depreciation deductions and divide this by the cost of the asset to get an estimate of the effective write-off of the asset (use the formula:
Σ depreciation p.a.(1+r)-n cost of asset
(where r = inflation rate)
Example:Plant and equipment which could be written off over 5 years if the inflation rate is 11%. effectively, only 74% of the assets cost will be written off.

Example: Depreciation - Real Analysis • Acme Ltd., a scrap metal dealer, is considering the acquisition of
a "Crushit" metal compactor at a cost of $25,000.
• The compactor is estimated to have a five-year life.
• Tax allowable depreciation is 20% prime cost per annum
• The company tax rate is 40%
• Expected inflation rate of 8% per annum for the next 5 years
• Depreciation Tax-Shield (nominal):
$25,000 x 0.20 = $5,000 x 0.40 = $2,000 p.a.

Under this approach it is necessary to deflate the depreciation tax shields by the expected inflation rate to take account of the loss of real value (i.e. loss of purchasing power) of the tax shields in an inflationary environment:
Year 1 = $2,000(1.08)-1 = $1,851.85
Year 2 = $2,000(1.08)-2 = $1,714.67
Year 3 = $2,000(1.08)-3 = $1,587.66
Year 4 = $2,000(1.08)-4 = $1,470.05
Year 5 = $2,000(1.08)-5 = $1,361.16

Capital Rationing Capital rationing – where a firm limits the total amount of funds to be invested
in projects. Therefore, even though certain projects may have a postive NPV, they could be
rejected due to capital (financing) constraints
Hard Capital RationingImposed by Capital Markets - markets will not provide sufficient finance
for a project at an acceptable cost. Does this mean capital markets are not efficient as they are not providing
funding to positive NPV projects?
Soft Capital RationingImposed by upper management to ensure subsidiaries prioritise
investments. Ensures discipline by lower level management – subsidiaries to only invest in
highest NPV projects.

Profitability Index (Benefit-Cost Ratio)
A project’s Profitability Index (PI) measures the return of a project relative to cost
PI = Present Value/Cost or
(NPV+Cost)/Cost
If PI > 1 = Accept the project (NPV must be positive)
If PI < 1 = Reject the project (NPV must be negative)

Capital Rationing
Both Projects B and C have a higher PI than Project A Total cost of Projects B and C = $15million Total cost of Project A = $15million
Rules: Maximise total NPV subject to the capital constraint (i.e. subject to
financing limits).
Use Profitability Index to rank projects as PI measures return relative to cost.
In the above example we would choose Projects B and C as they both have a higher PI than Project A and together B and C meet the capital constraint of $15million.

Optimal Economic Lives
Abandonment ValueCompare a project’s economic value (PV of future net cash-
flows) to its abandonment value (market/selling price at timeperiod T)
If abandonment value is greater than the PV of the future net cash-flows we should abandon the project
Replacement timingUse Equivalent Annual Costs (EAC) to determine the optimal
time to replace assetsEACs are used when a project is evaluated only on its costs
and revenues are ignored

Replacement timing
By comparing EACs over time, the firm can determine the optimal time to replace the asset.
In the following example, the firm should replace the asset at the end of 4 years (because EAC are lowest in Year 4).
