  1. NPV and other Investment Criteria Capital Budgeting Decisions Financial management: lecture 6

  2. Today’s agenda • Net Present Value (revisit) • Other two investment rules Financial management: lecture 6

  3. Net Present Value rule (NPV) • NPV is the present value of a project minus its cost • If NPV is greater than zero, the firm should go ahead to invest; otherwise forget about this project • A hidden assumption: there is no budget constraint or money constraint. Financial management: lecture 6

  4. NPV (continue) In other words: Managers can increase shareholders’ wealth by accepting all projects that are worth more than they cost. Therefore, they should accept all projects with a positive net present value if there is no budget constraint. Financial management: lecture 6

  5. Net Present Value NPV = PV - required investment Financial management: lecture 6

  6. An Example • An oil well, if explored, can now produce 100,000 barrels per year. The well will produce forever, but production will decline by 4% per year. Oil prices, however, will increase by 2% per year. The discount rate is 8%. Suppose that the price of oil now is $14 for barrel. • If the cost of oil exploration is $12.8 million, do you want to take this project? Financial management: lecture 6

  7. Solution • Visualize the cash flow patterns • C0=1.4, C1=1.37, C2=1.34, C3=1.31 • What is the pattern of the cash flow? • g=C1/C0 -1 =-0.0208=-2.1% • PV( the project) =C0+C1/(r-g)=15 • NPV=PV( the project ) -12.8>0 • What’s your decision? Financial management: lecture 6

  8. Two other investment rules • IRR rule • Payback period rule Financial management: lecture 6

  9. IRR rule Internal Rate of Return (IRR) – Single discount rate at which NPV = 0. IRR rule - Invest in any project offering a IRR that is higher than the opportunity cost of capital or the discount rate. Financial management: lecture 6

  10. IRR rule Example You can purchase a building for $350,000. The investment will generate $16,000 in cash flows (i.e. rent) during the first three years. At the end of three years you will sell the building for $450,000. What is the IRR on this investment? Financial management: lecture 6

  11. Internal Rate of Return Example You can purchase a building for $350,000. The investment will generate $16,000 in cash flows (i.e. rent) during the first three years. At the end of three years you will sell the building for $450,000. What is the IRR on this investment? Financial management: lecture 6

  12. Internal Rate of Return Example You can purchase a building for $350,000. The investment will generate $16,000 in cash flows (i.e. rent) during the first three years. At the end of three years you will sell the building for $450,000. What is the IRR on this investment? IRR = 12.96% Financial management: lecture 6

  13. Internal Rate of Return IRR=12.96% Financial management: lecture 6

  14. What’s wrong with IRR? Pitfall 1 - Mutually Exclusive Projects • IRR sometimes ignores the magnitude of the project. • The following two projects illustrate that problem. Example You have two proposals to choose between. The initial proposal (H) has a cash flow that is different from the revised proposal (I). Using IRR, which do you prefer? Financial management: lecture 6

  15. Internal Rate of Return (1) Example You have two proposals to choose between. The initial proposal (H) has a cash flow that is different from the revised proposal (I). Using IRR, which do you prefer? Financial management: lecture 6

  16. Internal Rate of Return Financial management: lecture 6

  17. What’s wrong with IRR (2)? Pitfall 2 - Lending or Borrowing? Example project C0 C1 IRR (%) NPV at 10% +150 +50 +$36.4 -100 J K -150 +50 -$36.4 +100 Financial management: lecture 6

  18. What’s wrong with IRR (3)? Pitfall 3 - Multiple Rates of Return • Certain cash flows can generate NPV=0 at two different discount rates. • The following cash flow generates NPV=0 at both (-50%) and 15.2%. • Example • A project costs $1000 and produces a cash flow of $800 in year 1, a cash flow of $150 every year from year 2 to year 5, and a cash flow of -150 in year 6. Financial management: lecture 6

  19. Payback period rule • Payback period is the number of periods such that cash flows recover the initial investment of the project. • The payback rule specifies that a project be accepted if its payback period is less than the specified cutoff period. The following example will demonstrate the absurdity of this rule. Financial management: lecture 6

  20. Payback period rule The following example shows that all the three projects have a payback period of 2. If the payback period used by the firm is 2, the firm can take project C and lose money.
