Capital budgeting with the Net Present Value rule 3. Impact of financing Professor André Farber Solvay Business School University of Brussels, Belgium Hanoi April 2000 1 Capital budgeting for the levered firm • With debt and equity, decision depends on financing mix. • Why? – – – – Tax subsidy to debt Cost of issuing new securities Subsidies to debt financing Cost of financial distress • 3 methods: – Adjusted-Present Value – Flow-to-equity – Weighted-average cost of capital Hanoi April 2000 2 Adjusted-Present-Value • • • • Divide and conquer! Step 1: Calculate NPV for unlevered project NPV Step 2: Calculate NPV of financing side NPVF Step 3: Add up. APV = NPV + NPVF Hanoi April 2000 3 APV - example • • • • Initial investment = 500 Expected future EBIT = 140 per year for indefinite future Corporate tax rate = 40% Cost of capital, all equity r0 = 20% • • • • Unlevered cash flow (UCF) = 140 (1 - 0.40) = 84 Present value of UCF = 84 / 0.20 = 420 NPV = -500 + 420 = -80 Unlevered project would be rejected! Hanoi April 2000 4 APV example: Introducing debt • • • • Now imagine the company borrows 300 Remaining investment (500 - 300 = 200) financed with equity. Borrowing rate = 10% Income statement unlevered levered EBIT 140 140 Interest 0 30 Tax saving Taxes 56 44 = 56 - 44 = 12 = 40% x 30 Earnings 84 66 Cash to investors 84 Hanoi April 2000 96 5 Valuing the Tax Shield • Annual tax shield from debt = TaxRate Interest rate Value of debt = TC rB B • Present value (perpetuity) = (TC rB B)/rB =TC B • In our example: PV(TaxShield) = 0.40 300 = 120 Hanoi April 2000 6 APV calculation (finished) • We now have the following for our project: • Net Present Value (all equity) • Present Value of Tax Shield • Adjusted Present Value - 80 +120 + 40 • Hanoi April 2000 7 Flow-to-Equity Approach • Valuation of cash flows from the project to the equityholders of levered firm (levered cash flow LCF). • LCF = UCF - (1-TC) x rB x B = UCF - rB x B + TC x rB x B Interest TaxShield • In our example: LCF = 84 - 30 + 12 = 66 Hanoi April 2000 8 Discounting Levered Equity Cash Flows • Because of debt, equity is more risky. Discount rate should take this additional risk into account. • The formula for the discount rate is: rS = r0 + (r0 - rB) x L/(1-L) • with L : debt-to-value ratio • In our example: L = 300 /(420 + 120) = 0.5555 • rS = 0.20 + (0.20 - 0.10) x 0.60 x 1.25 = 27.50% • Present value of levered cash flows = 66/.275 = 240 • NPVfor stockholders = 240 - 200 = 40 … same as APV Hanoi April 2000 9 Weighted-Average-Cost-of-Capital Approach • Discount unlevered cash flow using adjusted cost of capital. • rWACC = rs (1-L) + rB(1-TC) L • (Remember: L = B/V so 1-L = S/V) • In our example: • rWACC = 0.275 x 0.445 + 0.10 x 0.60 x .555 = 15.57% • Net present value = -500 + 84 / 0.1557 = 40 Hanoi April 2000 10 Alternative WACC formulas • Modigliani Miller : rWACC = r0 (1-TCL) – perpetuity – debt level constant • Miles-Ezzel: rWACC = r0 - L rB TC (1+r0)/(1+rB) – any set of cash flows – debt ratio constant Bt = L x Vt Hanoi April 2000 11 Comparing APV, FTE and WACC • Which approach is best? • APV – any type of side effect – unbundles present value – use APV when level of debt known • WACC, FTSE – takes into account interest tax shield – use WACC or FTSE when debt ratio constant Hanoi April 2000 12
