1. Chapter 9 Capital Budgeting Decision Models  Short-term versus Long-term Decisions  Payback Period  Discounted Payback Period  Net Present Value (NPV)  Internal Rate of Return (IRR)  Profitability Index (PI)

2. Short-term versus Long-term Decisions  Short-term decisions  Working capital decisions (Chapter 13)  In general, repetitive decisions  Long-Term decisions  Capital budgeting decisions (Chapter 9)  Impacts over many years  Difference  Time  Cost  Degree of Information

3. Payback Period  First and easiest model of capital budgeting  Answers the question, how soon will I get my money back?  Key Features  Need amount and timing of cash flows  Not concerned with cash flows after repayment  Ad hoc cutoff date for repayment

4. Payback Period  Clinko Copiers (example 9.1)  Initial investment is $5,000  Positive cash flow each year  Year 1 -- $1,500  Year 2 -- $2,500  Year 3 -- $3,000  Year 4 -- $4,500  Year 5 -- $5,500  Payback in 2 and 1/3 rd years…ignore years 4 and 5 cash flows

5. Payback Period  Strengthens  Easy to apply  Initial cash flows most important  Good for small dollar investments  Weaknesses  Ignores cash flows after cutoff period  Ignores time value of money  Corrections  Discount cash flows

6. Discounted Payback Period  Attempt to correct one flaw of Payback Period…time value of money  Discount cash flows to present and see if the discount cash flows are sufficient to cover initial cost within cutoff time period  Careful in consistency  Discounting means cash flow at end of period  Appropriate discount rate for cash flows

7. Discounted Payback Period  Discounted Cash Flows of Copiers A & B  Discounted at 6% (APR)  Both 3 year discounted paybacks with annual cash flows  Copier A – 26 months with monthly cash flows  Copier B – 29 months with monthly cash flows  Potential for poor choice  Large late positive cash flows  Longer positive cash flows

8. Net Present Value (NPV)  Correction to discounted cash flows  Includes all cash flows in decision  Changes decision (go vs. no-go) to dollars, not arbitrary cutoff period  The Decision Model (a.k.a. Discounted Cash Flow Model)  Need all cash flows  Need appropriate discount rate

9. Net Present Value (NPV)  Decision  Accept all positive NPVs  Reject all negative NPVs  Copier Example  Copier A – NPV is $5,530.91 – Accept  Copier B – NPV is $9,253.09 – Accept  Model good for comparing projects  Select project with highest NPV  Can assign different discount rates to projects

10. Net Present Value (NPV)  The Decision Model  Incorporates risk and return  Incorporates time value of money  Incorporates all cash flows

11. Internal Rate of Return (IRR)  Model closely resembles NPV but…  Finding the discount rate (internal rate) that implies an NPV of zero  Internal rate used to accept or reject project  If IRR > hurdle rate, accept  If IRR < hurdle rate, reject  Very popular model as “managers” like the single return variable when evaluating projects

12. Internal Rate of Return (IRR)  Process difficult without calculator or spreadsheet – iterative process  Need timing and amount of cash flows  Examples  Copier A – IRR is 41%  High return…accept project  Assumes can borrow funds for project for less than 41%

13. Internal Rate of Return (IRR)  Some problems with IRR  Cross-over Rates flip projects  Using NPV profiles, project choice changes at cross-over rate so need to know both hurdle rate and cross-over rate  Cross-over rate is where two projects have same NPV  Multiple IRRs  Projects with changing cash flows can have multiple IRRs  Which is the correct IRR? Don’t know  Risk of Project is not included  IRR calculation void of risk of project  Risk must be implied with different hurdle rates

14. Profitability Index (PI)  Modified version of NPV  Decision Criteria  PI > 1.0, accept project  PI < 1.0, reject project

15. Profitability Index (PI)  Close to NPV as we calculate present value of future positive cash flows (present value of benefits) and initial cash flow (present value of costs)  PI = (NPV + Initial cost) / Initial Cost  Answer is modified return  Choosing between two different projects?  Higher PI is best choice…  Careful, cannot scale projects up and down

16. Profitability Index (PI)  Example of Large Copier and Mini-Copier  Large Copier B PI is 2.85 (normal level of risk)  Mini Copier PI is 2.95  Pick Mini Copier  Problem with copier choice  Original investment in mini-copier only $500  Original investment in Copier B is $5,000  Need to buy 10 mini-copiers to match production of Copier B…
