Cash flows
-NPV Rule- Determining Cash flows-Payback period Rule-Discounted Payback Period-Internal Rate of Return-Independent VS Mutually Exclusive-Profitability Index
Net Present Value RuleInvestment decisions from the
perspective of corporate finance is known as capital budgeting.
Net present value is one of the criteria to choose between capital budgeting projects.
NPV is the difference between intrinsic value and the cost of the project◦NPV = (PV of future cash flows) – cost
NPV Rule: Accept the project if NPV is positive, reject if NPV is negative.
Net Present Value RuleExample: The Alpha Corporation is
considering investing in a riskless project costing $100. The project receives $107 in one year and has no other cash flows. The discount rate is 6%. The NPV is
This example deals with a riskless project which is impossible in reality. To incorporate the risk in calculation the discount rate can be increased, which will be discussed in later chapter
Net Present Value RuleBenefits of NPV:
◦One way of determining the value of a firm is to add the values of different projects, divisions, or other entities within the firm. This property is called “value additivity” and it
implies that the contribution of any project to the firm’s value is the NPV of the project.
◦NPV uses cash flows and not accounting profit
◦NPV uses all cash flows of the project including the initial cost and salvage value
◦NPV discounts the cash flows properly
Determining the Cash FlowsThe cash flows that should be included
in a capital budgeting analysis are those that will only occur if the project is accepted
These cash flows are called incremental cash flows◦Cash basis calculation is needed not accrual
basis The stand-alone principle allows us to
analyze each project in isolation from the firm simply by focusing on incremental cash flows
Determining the Cash FlowsSunk costs – costs that have already been incurred in
the past and cannot be removed◦ Should not be considered in investment decision
Opportunity costs – the most valuable alternative that is given up if a particular investment is undertaken.◦ Should be included in investment decision calculations◦ Always an outflow (negative) adjusted with initial outlay
Side effects◦ Positive side effects – benefits to other existing
projects◦ Negative side effects (a.k.a. erosion) – costs to other
existing projects◦ Should be included in investment decision
calculations
Determining the Cash FlowsChanges in net working capital – the extra
amount of cash required for daily operations of the project◦Should be included in the investment decision
Financing costs – interest expense, dividends, principal paid etc.◦Should not be included in investment decision◦These cashflow do not depend on operation.
Taxes – If a particular component is taxed then after-tax cashflow needs to be considered.
Determining the Cash FlowsIncremental project cash flows
with all these components suggest that it is the Free Cash Flow (FCF) of the project◦Another name is Cash Flow From
Asset (CFFA)◦FCF = EBIT(1-T) + Depreciation –
Change in NWC – Change in capital expenditure
Payback Period RulePayback Period is the method for
measuring the time it takes to recover the initial cost of a project
If a project requires an initial investment of $50,000 and the following cash flows of $30,000; $25,000; and $10,000 then its payback period is◦ -$50,000 + $30,000 + $20,000 (out of
$25,000)= 0◦Payback = 1 + (20,000/25,000) = 1.8 years
Payback period rule: Set a cutoff date and select projects with payback shorter than cutoff.
Payback Period RuleProblems of Payback Period:
◦Payback period does not consider time value of money
◦Payback period does not consider the cash flows after the payback
◦The choice of the cutoff date is random and does not have any proper standard.
Discounted Payback PeriodTo address the timing issue of the
payback period an alternative method used is discounted payback period.
Discounted payback period is the method for measuring the time it takes to recover the initial cost of a project with the present value of all the future cash flows.
Discounted Payback PeriodSuppose the discount rate is 10%
and the cash flows on a project are given by -$100, $50, $50, $20. ◦The discounted cash flows are: [-
$100, ($50/1.1), ($50/1.12), ($20/1.13)] = (-$100, $45.45, $41.32, $15.03)
◦Discounted period is 2 + [(100-45.45-41.32)/15.03] = 2.88 years
Internal Rate of Return (IRR)A project’s IRR is the discount rate that
forces the PV of cash inflows to equal the cost◦This is equivalent to forcing the NPV to equal
zero.◦Thus IRR does not depend on market interest
rate. It is completely intrinsic.◦There is no fixed formula to calculate IRR other
than the trial and error methods to make NPV zero.
◦ IRR Rule: Accept the project if IRR is greater than discount rate, reject it if IRR is less than discount rate.
Internal Rate of Return (IRR)The IRR rule mentioned in the previous slide
is applicable only to projects which has the cash flow pattern of a single outflow followed by several inflows. ◦ In this sequence the decision of NPV and IRR
almost always matchIf the pattern of cash flow is an inflow
followed by outflows then the rule is reversed.
If the pattern involves several changes of cash flow signs (i.e. outflow, inflow, inflow, outflow etc.) then there are multiple IRRs for a single project
Internal Rate of Return (IRR)IRR= Ra + (NPVa) * (Rb - Ra) (NPVa - NPVb)
Here, ◦Ra = discount rate that gives the
positive net present value◦NPVa = positive NPV ◦NPVb = negative NPV◦Rb = discount rate that gives the
negative net present value
Modified IRR (MIRR)When multiple IRR arises an
alternative method can be modified IRR (MIRR)◦MIRR combines multiple cash flows until
only one change of sign remains and then the IRR rule is applied.
◦Using the discount rate the future cash outflows are discounted to present time
◦They are then added with the initial investment to have single negative cash flow while the others are positive.
◦Then the IRR method is applied
The Rule Chart
Independent VS Mutually ExclusiveThe rules of capital budgeting decisions
discussed so far are applicable to choose in between independent projects only.◦ Independent projects are those whose
acceptance or rejection is independent of each other or any other projects.
These rules will be different in cases of mutually exclusive projects.◦ If two projects are mutually exclusive then you
can accept either one and have to reject the other or reject both. You cannot accept both projects.
Independent VS Mutually ExclusiveMutually Exclusive Investment
Rules:◦Accept the project with the higher NPV if
both NPV are positive. If both are negative then reject both
◦Accept the project with the shorter payback or discounted payback period if both are below cutoff date. If both are above cutoff date then reject both
◦Accept the project with higher IRR if both are above discount rate. If both are below discount rate then reject both
Profitability IndexProfitability Index (PI) = (PV of
cash flows after initial investment)/Initial investment◦Very similar to NPV◦Does not work with mutually
exclusive projects. Then revert back to NPV.
PI Rule: Accept project if PI>1, reject if PI<1
