[2] Investment Decisions Flashcards
What does Present Value show?
a measure that expresses these future
revenues in current terms
How do we calculate PV when assets provide returns over several periods?
PV = β_(π‘=1)^πγπΆ_π‘/((1+π_π‘ )^π‘ )=πΆ_1/((1+π_1))+πΆ_2/((1+π_2 )^2 )+πΆ_3/((1+π_3 )^3 )+β¦+πΆ_π/((1+π_π )^π )
where: Ct is the cash flow at period t (assuming that it may vary over time) rt is the rate of the return on the asset at period t (or the opportunity cost of the investment; may also vary over time),
T is the total number of periods during which the asset yields returns.
What is the opportunity cost of capital? + eg
The return foregone from a certain investment activity instead of investing to an alternative activity (with the same level of risk).
- If you invest in property instead of buying bonds, then the interest rate on bonds, say r , is the opportunity cost of capital.
What is the formula for NPV?
What is the decision rule?
NPV = PV - Cost of Investment
Decision Rule ββ> βAccept Investments that yield positive NPVβ
Ratio of NPV to cost of investment gives what?
Profitability index: Pl = NPV/Q
Pitfalls of Profitability index? [4]
- possible bias against costly projects⦠although they may have a larger NPV.
- resources/funds can be constrained in more periods.
- cannot cope with mutually exclusive projects (eg: require the same piece of land, but different useful life),
- when one project is dependent on another (eg: one is an add-on to the other).
Book Rate of Return
Prospective book income as a proportion of the book value of the assets that the firm is proposing to acquire:
BRR = book income book assets
Pitfalls of Book Rate of Return measure of a return on investment? [4]
- bias against more costly projects with higher NPV;
- average profitability of past investments is not the right hurdle for new investments;
- depends on which items the accountant treats as capital investment (and how rapidly they are depreciated) and which items are operating expenses;
- therefore, an accountantβs classification of cash flows, may yield different results.
What is payback period?
Payback period: measures the number of years it takes for the cumulative cash flow from the project to equal the initial investment.
What is the payback rule?
a project should be accepted if its payback period is less than some specific cut-off period.
Pitfalls of the payback rule? [2]
all cash flows after the cut-off date are ignored (although they may be significantly high);
all cash flows before the cut-off date are treated equally (without taking account of discounting).
What is the internal rate of return? [IRR]
What is it also known as?
What is the rule for if the project should be undertaken?
It is the rate of discount that makes NPV = 0.
It is also called the discounted cash flow rate of return.
if the lRR is greater than the actual opportunity cost of capital (r), i.e. lRR >r =} the project should be undertaken.
What is the formula for NPV involving IRR?
What technique is often used ? What are you trying to achieve?
- NPV of a project is steadily declining function of the
____ _____.
πππ= T_(π‘=1) βπΆπ‘/((1+πΌπ π )^π‘ ) βπ=0
Trial and Error to get NPV = 0
Discount rate
Pitfalls of IRR? 4
1) in the case of borrowing (positive initial inflow; negative, discounted future outflows) the IRR rule works the other way around, i.e. opportunity cost > IRR
2) when project incurs some future costs, there may be multiple lRRs⦠or even none!
3) when there are more than one opportunity cost of capital, obtaining the lRR becomes even more complex. Which r do we compare with or weighted av.?
4) it can be misleading with mutually exclusive projects the lRR is unreliable in ranking projects of different scale and with different patterns of cash flow over time.
What external factors does IRR ignore?
excludes external factors, such as the risk-free rate, inflation, the cost of capital, or various financial risks
