Accept / Reject criteria for a project NPV > Zero Accept Investment NPV < Zero Reject Investment NPV = Zero May Accept Investment 5 Taxation effects of the relevant cash flows 1. Operating cash flows Refers to revenue expenditure or income affecting operating profit Revenues (inflows) Expenses (outflows) increase profits, resulting in tax increases shown as cash outflows reduce profits, resulting in tax savings shown as cash inflows 2. Capital cash flows Capital allowances Disposal of assets allowable against profits resulting in tax savings shown as cash inflows Balancing allowance / charge profit on disposal loss on disposal tax payment tax relief on disposal 3. Timing The local tax laws define the period the tax flows relate to 6 Linear programming approach to multi- period capital rationing Multi-period capital rationing arises when there is more than one cash outflow and these cash outflows arise in different time periods for different projects. Firm objective is to choose that package of projects which gives the maximum total NPV subject to the capital constraints. As the number of alternatives and constraints increase, the decision-making process becomes more complex. Use of a mathematical programming method is recommended. Linear programming (LP) is a mathematical technique used to arrive at the optimal production plan & optimal resource allocation with an objective of cost minimisation and profit maximisation. 7 Internal rate of return (IRR) Internal Rate of Return (IRR) It is the required rate of return or cost of capital which produces an NPV of zero when used to discount the project’s cash flows. Present value of cash inflows = present value of cash outflows Situations for the calculation of IRR When the project cash inflows are identical When the project cash inflows are not identical Continued … 8 Continued … Calculation of IRR when the project cash inflows are identical Factor / Payback = cash outflow annual cash inflow . Go across the row of the year (equivalent to the life of the project) of the table of cumulative present values and find the closest figure to the factor as calculated above The corresponding rate of that figure is the IRR Criteria: IRR ≥ minimum desired rate of return, the investment project should be accepted. IRR < desired rate of return, the project should be rejected. 9 Calculation of IRR when the project cash inflows are not identical Calculation of IRR when the project cash inflows are not identical In such a situation, the interpolation method is to be used. The NPV at two discount rates will be required (preferably a positive and negative NPV). A x b - a % A B IRR a Where a is lower of the two rates of return used b is higher of the two rates used A is NPV obtained using rate a B is NPV obtained using rate b 10 Modified internal rate of return (MIRR) Modified Internal Rate of Return (IRR) Discount rate that equates present value of the terminal cash inflow to the initial investment in year zero n MIRR = Terminal value of cash flows --------------------------------------------------- - 1 Present value of investment outlay n Terminal Value = ∑ CFt (1+r) n-t T=0 3 Discount rate is IRR Find discount rate that equates terminal value to initial investment outlay Calculate terminal value of project cash flows using reinvestment rate / cost of capital 11 2 1 Free cash flow of equity (FCFE) Cash surplus generated by a firm which is available for reinvestment or redistribution Free cash flows of equity (FCFE) FCFF Revenues Less: Operating expenditure Less: Taxation Less: Capital expenditure Add: Depreciation & amortisation Add / (Less): Changes in working capital X (X) X X (X) X FCFF X FCFE Net income after taxation Less: Capital expenditure Add: Depreciation & amortisation Add: New debts issued Less: Debt repayments Add / (Less): Changes in working capital X (X) X X (X) X Less: Preference dividends paid FCFE (X) X Refer to Example (page 195) 12 Advise on a specified capital investment programme a firm’s current & projected dividend capacity Function of free cash flow to equity (FCFE) Dividends Other than FCFE, reasons: future investment requirements, stability requirements, taxation, etc. Excess cash flow after all positive NPV can be: Distributed in large cash dividends to shareholders Share purchase schemes; or Higher level of gearing which increases interest payments and reduces discretionary cash flow Formula Dividends + Equity repurchase Cash to shareholders: FCFE ratio = FCFE 13 Valuation of a firm using free cash flow Value of a firm is the discounted value of future cash flow available for payment as dividend / for investment FCFF at constant rate FCFF0 (1 + g) Vo = ------------------------Re – g Where Vo = Value of the firm Re = Expected rate of return g = Expected growth rate Terminal values- FCFF growing at a rate higher than the growth rate of economy n V0 = ∑ T=1 FCFFt (1 + g) Terminal value of business ---------+ ---------------------------------------(1 + Re) t (Re - g) Where Re is the cost of capital 14 Valuation of a firm using free cash flow to equity Value of equity is the discounted value of future cash flow available for payment as dividend / for investment FCFE at constant rate Formulae remains same as value of firm. Use FCFE in place of FCFF Terminal values- FCFE growing at a rate higher than the growth rate Formulae remains same as value of firm. Use FCFE in place of FCFF Refer to Example (page 197) 15 Monte Carlo simulation Assessment of risk is important & must be incorporated in the investment appraisal process. Cash flows can vary due to risks. Statistical tool of simulation can be applied to measure such risk. Simulation - quantitative procedure used to describe a process by developing a model of that process, and then conducting a series of organised experiments to predict the probable outcome of that process. Technique of spread sheet simulation Monte Carlo simulation Used to calculate the NPV from a combination of economic variables which affect the NPV calculation 16 Steps for adjustments Market factors Investment cost factors 1. Select on observation from each factor 2. Assign probability values to factors 3. Generate random numbers for each factor 4. Calculate NPV by electing value of each factor corresponding with random number 5. Repeat process several times (process is called iteration) 6. Will generate probability distribution (PD) of NPV 7. Plot PD of NPV on a graph Continued … 17 Operating & fixed cost factors Continued … Significance of simulation output Standard deviation Used to measure risk of projects Expected net present value (ENPV) Weighted average of returns where probabilities of possible outcomes are used as weights Process of iterations gives range of outputs. If number of iterations is large, outputs follow a normal probability distribution. Normal probability distribution can be used to further analyse the risk in the investment appraisal process. Normal probability distribution is a symmetric, continuous bell-shaped curve 18 Project value at risk (project VaR) Project VaR measures the potential loss in the value of a project over a defined period for a given confidence level Used by management in decision making signifies maximum amount by which the actual NPV of a project will be lower than its expected NPV Project VaR = Z x x T Where: Z is the standard normal variable is the standard deviation T is the time period over which the value at risk will be calculated. Usefulness of VaR Project VaR can be used by the management of a company to decide whether to accept or reject a particular investment project taking into account the expected NPV and the risk. 19 Recap Capital Investment Appraisal using NPV Capital Investment Appraisal using IRR & MIRR Forecast a company’s free cash flow and its free cash flow to equity (pre and post capital reinvestment).
