Net Present Value and Other Investment Criteria Flashcards
Capital Budgeting and Net Present Value
Capital budgeting is the most important issue in corporate finance, focusing on the process of allocating capital to projects that create value for the owners.
Fundamental business decisions involving capital budgeting include choosing product lines, entering new markets, launching new products, or deciding which services to offer.
An investment is worth undertaking if it is worth more than it costs once it is in place.
Net Present Value (NPV) is the difference between an investment’s market value and its cost. It serves as a measure of how much value is created or added today by undertaking an investment.
The NPV rule states that an investment should be accepted if the NPV is positive and rejected if the NPV is negative.
The capital budgeting process is essentially a search for investments with positive NPVs.
Estimating NPV involves:
Estimating future cash flows expected from the business.
Applying discounted cash flow (DCF) valuation by discounting future cash flows to estimate their present value (PV).
Calculating the difference between the PV of subsequent cash flows and the initial cost.
Example: Estimating NPV for an Organic Fertilizer Business
Initial investment cost:
Estimated yearly cash revenues:
Estimated yearly cash costs (including taxes):
Net annual cash flow:
Project duration: years
Salvage value of equipment at year 8:
Required discount rate on new projects:
Present Value calculation:
NPV calculation:
Since the NPV is negative, this is not a good investment. If there are shares outstanding, taking this project would result in a loss of value of per share.
The Payback Rule
The payback period is the amount of time required for an investment to generate cash flows sufficient to recover its initial cost.
The payback rule states that an investment is acceptable if its calculated payback period is less than some prespecified number of years.
Shortcomings of the payback rule:
The time value of money is completely ignored.
Risk differences between projects are not considered.
There is no economic rationale for picking a specific cutoff point.
It is biased toward shorter-term, liquid investments.
It ignores cash flows occurring after the payback period.
Redeeming qualities of the payback rule:
It is simple to use for minor decisions where the cost of detailed analysis exceeds the potential loss.
The bias toward liquidity is useful for cash-constrained firms.
It accounts for the uncertainty of far-future cash flows by ignoring them.
Example of payback period calculations:
An initial investment of that returns in Year 1 and in Year 2 has a payback of exactly years.
Project A: Payback is years.
Project B: Never pays back.
Project C: Payback of exactly years.
Project D: Has two correct payback periods of and years.
Project E: Pays back in months.
The Discounted Payback Rule
The discounted payback is the length of time required for an investment’s discounted cash flows to equal its initial cost.
This rule ensures that the project breaks even in an economic or financial sense, meaning the initial investment is recovered along with the interest that could have been earned elsewhere.
A project that pays back on a discounted basis must have a positive NPV.
Advantages:
Includes the time value of money.
Does not accept negative estimated NPV investments.
Disadvantages:
May reject positive NPV investments.
Requires an arbitrary cutoff point.
Ignores cash flows beyond the cutoff.
Is as complex as NPV but lacks the conceptual rigor.
The Average Accounting Return (AAR)
The AAR is an investment's average net income divided by its average book value.
Formula:
Example of a store investment:
Initial improvement cost:
Project life: years
Depreciation: Straight-line over years ( per year).
Average Book Value:
If average net income over the years is , the AAR is .
AAR Rule: A project is acceptable if its AAR exceeds a target average accounting return.
Drawbacks of AAR:
It is not a true rate of return because it uses accounting numbers (net income and book value) rather than cash flows and market value.
It ignores the time value of money.
It uses an arbitrary benchmark cutoff rate.
The Internal Rate of Return (IRR)
The IRR is the discount rate that makes the NPV of an investment zero.
It is an internal measure because it depends only on the cash flows of the specific project, not on external rates.
IRR Rule: Accept the project if the IRR is greater than the required return; reject if it is less.
The NPV profile is a graph illustrating the relationship between a project's NPV and various discount rates. The point where the curve crosses the x-axis (where NPV = 0) is the IRR.
IRR and NPV rules generally lead to identical decisions if the project's cash flows are conventional (initial cost followed by all positive inflows) and the project is independent.
Problems with the IRR:
Nonconventional cash flows: If cash flows change signs more than once, there may be multiple IRRs (multiple rates of return problem).
Mutually exclusive investments: Situations where taking one project prevents taking another. IRR may rank a project with a lower NPV higher than a project with a larger NPV.
Investing vs. Financing: For financing-type projects (where money is received initially), the project is only acceptable if the IRR is lower than the required return.
Modified Internal Rate of Return (MIRR)
MIRR is used to address the multiple IRR problem by modifying cash flows before calculating the return.
Method 1: The Discounting Approach
Discount all negative cash flows back to Year 0 and add them to the initial cost.
Calculate the IRR using these modified flows.
Method 2: The Reinvestment Approach
Compound all cash flows except the initial one to the end of the project's life.
Example: For a -year project with a required return, an initial cost of , and subsequent flows of and , the modified Year 2 flow is . The MIRR is .
Method 3: The Combination Approach
Negative cash flows are discounted to the present, and positive cash flows are compounded to the end.
Critique of MIRR: It is not truly "internal" because it relies on an externally supplied discount or compounding rate. Reinvestment of interim cash flows does not change the project's inherent value.
The Profitability Index (PI)
The Profitability Index, or benefit-cost ratio, is the present value of an investment’s future cash flows divided by its initial cost.
Formula:
Interpretation: A PI of means that for every dollar invested, the project creates in value, or in NPV.
If NPV is positive, PI will be greater than . If NPV is negative, PI will be less than .
Capital Budgeting in Practice
Firms often use multiple criteria (NPV, IRR, Payback, PI) to evaluate proposals because NPV is only an estimate based on uncertain future data.
Large-scale capital spending examples (2020 projections):
ExxonMobil: Expected to billion in outlays (up from billion in 2019).
Chevron: Expected to billion (similar to billion in 2019).
Walmart: Projected billion.
AT&T: Projected billion.
Surveys indicate that NPV and IRR are the most frequently used techniques in modern practice.
Selected Concept Questions
Under what circumstances will the IRR and NPV rules lead to the same accept-reject decisions? They align for independent projects with conventional cash flows.
What does the profitability index measure? It measures the value created per dollar invested.
What advantage(s) does the discounted payback have over the ordinary payback? It incorporates the time value of money.
What are the weaknesses of the AAR rule? It ignores the time value of money, uses accounting book values instead of market values, and lacks an objective cutoff point.
