1 CapitalBudgeting Payback Net present value (NPV) Internal rate of return (IRR) Profitability index (PI) Modified internal rate of return (MIRR)

2 What Is capital budgeting? Analysis of potential additions to fixed assets. Long-term decisions; involve large expenditures. Very important to firm’s future.

3 Steps 1. Generate ideas. 2.Estimate CFs (inflows & outflows). 3.Assess riskiness of CFs. 4.Determine k = WACC (adj.). 5.Find NPV and/or IRR. 6.Accept if NPV > 0 and/or IRR > WACC.

4 An Example of Mutually Exclusive Projects BRIDGE VS. BOAT TO GET PRODUCTS ACROSS A RIVER.

5 Normal Project Cost (negative CF) followed by a series of positive cash inflows. Nonnormal Project One or more outflows occur after inflows have begun. Most common: Cost (negative CF), then string of positive CFs, then cost to close project. Nuclear power plant, strip mine.

6 Inflow (+) or Outflow (-) in Year NNN N N

7 What is the payback period? The number of years required to recover a project’s cost, or how long does it take to get our money back?

8 Payback for Project L (Long: Most CFs in out years) CF t Cumul Payback L = /80 = years

9 CF t Cumul Payback S = /50 = 1.6 years Project S (Short: CFs come quickly) Payback is a type of breakeven analysis.

10 Ignores the TVM. Ignores CFs occurring after the payback period. Provides an indication of a project’s risk and liquidity. Easy to calculate and understand. Weaknesses of Payback Strengths of Payback

12 Sum of the PVs of inflows and outflows. Net Present Value (NPV) If one expenditure at t = 0, then NPV =   n t=0 CF t (1 + k) t NPV =  - CF 0. n t=1 CF t (1 + k) t

13 What is Project L’s NPV? % Project L: = NPV L NPV S = $19.98.

15 NPV= PV inflows - Cost = Net gain in wealth. Accept project if NPV > 0. Choose between mutually exclusive projects on basis of higher NPV. Adds most value. Rationale for the NPV Method

16 Using NPV method, which project(s) should be accepted? If Projects S and L are mutually exclusive, accept S because NPV S > NPV L. If S & L are independent, accept both; NPV > 0. Note that NPVs change as cost of capital changes.

17 Internal Rate of Return (IRR) 0123 CF 0 CF 1 CF 2 CF 3 CostInflows IRR is the discount rate that forces PV inflows = cost. This is the same as forcing NPV = 0.

18 NPV:Enter k, solve for NPV. IRR:Enter NPV = 0, solve for IRR.  t n t t CF k NPV     0 1.

19 What is Project L’s IRR? IRR = ? PV 3 PV 2 PV 1 0 = NPV Enter CFs in CFLO, then press IRR: IRR L = 18.13%.IRR S = 23.56%.

20 Rationale for the IRR Method If IRR > WACC, then the project’s rate of return is greater than its cost-- some return is left over to boost stockholders’ returns. Example:WACC = 10%, IRR = 15%. Profitable.

21 If IRR > k, accept project. If IRR < k, reject project. IRR Acceptance Criteria

22 If S and L are independent, accept both. IRRs > k = 10%. If S and L are mutually exclusive, accept S because IRR S > IRR L. Using IRR method, which project(s) should be accepted? Note that IRR is independent of the cost of capital, but project acceptability depends on k.

23 PI =. PV of inflows PV of outflows Define Profitability Index (PI)

24 Calculate each project’s PI. Project L: $ $ $60.11 $100 Project S: $ $ $15.03 $100 PI L = = PI S = = 1.20.

25 If PI > 1, accept. If PI < 1, reject. The higher the PI, the better the project. For mutually exclusive projects, take the one with the highest PI. Therefore, accept L and S if independent; only accept S if mutually exclusive. PI Acceptance Criteria

26 Yes, modified IRR (MIRR) is the discount rate which causes the PV of a project’s terminal value (TV) to equal the PV of costs. TV is found by compounding inflows at WACC. Thus, MIRR forces cash inflows to be reinvested at WACC. Managers prefer IRR to NPV. Can we give them a better IRR?

27 $158.1 (1+MIRR L ) % MIRR for Project L (k = 10%): % TV inflows PV outflows MIRR = 16.5% MIRR L = 16.5% $100 =

28 MIRR correctly assumes reinvestment at opportunity cost = k. MIRR also avoids problems with nonnormal projects. Managers like rate of return comparisons, and MIRR is better for this than IRR. Why use MIRR rather than IRR?

29 When there are nonnormal CFs, use MIRR: ,0005,000,000-5,000,000 PV 10% = -4,932, TV 10% = 5,500, MIRR = 5.6%

30 Accept Project P? NO. Reject because MIRR = 5.6% < k = 10%. Also, if MIRR < k, NPV will be negative: NPV = -$386,777.
