4MODIFIED INTERNAL RATE OF RETURN
¾Traditional Internal Rate of Return has a major limitation as it implies that the cash flows from a project can be reinvested at the IRR itself. This may be an over-optimistic assumption, particularly when the IRR is significantly higher than the firm’s hurdle rate i.e. WACC.
¾Modified Internal Rate of Return (MIRR) overcomes this problem and assumes that the cash flows arising from a project (excluding the initial investment) are reinvested at the firm’s hurdle rate.
¾Method of calculation:
Each annual cash flow is projected forward at the firm’s hurdle rate to obtain a terminal value at the end of the project
MIRR = n |
|
Terminal Value of project returns |
-1 |
|
Present Value of investment outlay |
||
|
|
|
|
|
where n = number of years |
|
Example 3
A project has the following forecast cash flows:
T0 |
T1 |
T2 |
T3 |
T4 |
(34,000) |
7600 |
16,500 |
13,000 |
6,600 |
The firm’s cost of capital is 8%.
Required:
Estimate the MIRR.

5ANALYSING PROJECT LIQUIDITY
5.1Traditional Measures
¾Traditional measures of project liquidity have significant weaknesses:
Payback period: ignores the time value of money and ignores cash flows beyond the payback date
Discounted payback; takes into account the time value of money but still ignores post-payback cash flows
¾Clearly there is a need for measures which take into account cash flows over the whole life of the project.
5.2Project Recovery
¾Recovery period is the number of years required to recover the initial investment, taking into account the time value of money.
¾Unlike discounted payback, the calculation of recovery takes into account cash flows over the whole life of the project.
Recovery = |
Present Value of investment outlay |
× project life |
|
Present Value of project returns |
|||
|
|
¾However recovery period assumes that project returns are generated at a constant rate over the life of the project. This weakness can be resolved by calculating project duration.
5.3Project Duration
¾Duration measures the time over which half of the project’s returns are generated. Method:
Calculate the present value of each future cash flow
Express each year’s discounted cash flow as a proportion of the total present value of the project’s returns.
Multiply each proportion by the relevant year
Sum the weighted years

6ANALYSING PROJECT RISK
6.1Use of simulation
¾Traditional sensitivity analysis can be used if one project variable changes independently of all others. However, some project variables may be interdependent e.g. costs and market share.
¾Simulation is a technique which allows more than one variable to change at the same time.
¾One example of simulation is the “Monte Carlo” method. Calculations will not be required in the exam, an awareness of the stages is sufficient.
6.2Stages in a Monte Carlo simulation
(1)Specify the major variables.
(2)Specify the relationship between the variables.
(3)Attach probability distributions (e.g. the normal distribution) to each variable and assign random numbers to reflect the distribution.
(4)Simulate the environment by generating random numbers.
(5)Record the outcome of each simulation.
(6)Repeat simulation many times to obtain a frequency distribution of the NPV
(7)Determine the expected NPV and its standard deviation.
6.3 |
Advantages of Monte Carlo |
9 |
It gives more information about the possible outcomes and their relative probabilities. |
9 |
It is useful for problems which cannot be solved analytically. |
6.4 |
Limitations of Monte Carlo |
8It is not a technique for making a decision, only for obtaining more information about the possible outcomes.
8It can be very time-consuming without a computer.
8It could prove expensive in designing and running the simulation, even on a computer.
8Simulations are only as good as the probabilities, assumptions and estimates made.

6.5Value At Risk (VAR)
¾VAR gives an indication of the potential loss which is likely to occur at a given level of confidence
Project VAR = N(confidence level) × s × √T Where:
N(confidence level) is the number of standard deviations from the mean for the given confidence level (extracted from the normal distribution tables)
s is the annual standard deviation of the project’s returns
T is the number of years of the project.
Example 5
Monte Carlo simulation has produced the following output for a potential 10 year project:
¾Expected NPV $1.964m
¾NPV volatility $1.02m (annual standard deviation)
Required:
(a)What is the probability that the project will produce a negative NPV?
(b)What is the Value At Risk at the 95% and 99% confidence levels?
Solution

SESSION 06 – ADVANCED INVESTMENT APPRAISAL
6.6Stress Testing
¾Stress testing is designed to test the sensitivity of a project’s value at risk under the worst set of outcomes that can reasonably be expected to occur
¾This requires a careful evaluation of the worst possible outcomes – possibly by looking at the response of the model to extreme external events e.g. major currency or interest rate changes.
Key points
Traditional NPV calculated using WACC does not deal well with a project whose finance significantly changes the firm’s capital structure.
In this situation it is preferable to use APV which splits the operational side of a project from its financing implications and values each separately before finding the overall impact of the project with the proposed financing.
Multi-period capital is where cash for investment is a limiting factor in several years. In this case it is necessary to formulate a linear programming model and solve graphically.
Traditional IRR assumes that project cash flows can be reinvested at the IRR itself – often an optimistic assumption. Modified IRR makes the more realistic assumption that cash flows can be reinvested at the cost of capital.
Various measures of project liquidity can be calculated - listed in order of increased usefulness – payback, discounted payback, recovery and duration.
Project risk can be modelled using Monte Carlo simulation, the results of which can then be used for VAR analysis.

¾calculate the APV of a project to account for its financing side-effects;
¾discuss the application of Real Options Pricing Theory in finding the full strategic value of a project;
¾deal with both single period and multi-period capital rationing;
¾calculate MIRR as a more realistic measure of project return than traditional IRR;
¾calculate measures of project liquidity and project risk.

(b)WACC adjusted for business and finance risk
To adjust for the business risk of the project we should use the cost of equity of a firm engaged in a similar line of business to the new project. In this case we will employ the equity beta of the plastics industry.
However, as the plastics industry is at a different level of gearing to the project we should also adjust for financial risk by finding the asset β
ßa = ße
ßa
E
E + D(1 − t)
= 1.356 × |
5 |
5 + 1(1 −0.35) |
|
= 1.2 |
|
Equity beta for an ungeared firm in the plastics industry = 1.2
As Blades’ plastics operation will be 40% debt : 60% equity, we must “regear” using the same equation.

ß equity geared |

|
This would give a cost of equity of 10% + 1.72 (15% – 10%) = 18.6% and a WACC for the plastics project of
