Valuing Levered Projects Interactions between financing and investing Nico van der Wijst 1 D. van der Wijst Finance for science and technology students

1 First analyses 2 3 4 2 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Finance - investment interactions Concern very common business decisions: Telenor wants to build new mobile network but finance the investment with more debt Transport company considers fleet expansion but wants to lease, not buy the trucks Oil company wants to diversify into green energy project has very different risk characteristics different debt ratio also 3 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Structure of decision problem: 1 Accept project if its NPV>0 2 to calculate NPV we need: 1 cash flows (are given here) 2 discount rate (chapter s topic) 3 Discount rate depends on: 1 business risk or, equivalently, the OCC 1 calculated from existing operations if business risk is same 2 otherwise, has to estimated from other companies 2 financial risk, division over debt and equity 1 depends on debt ratio 2 and financing rule (predetermined of rebalanced) 4 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Basic elements introduced in derivation MM proposition 2 with taxes: Costs of debt, equity increase with leverage taxes influence cost of capital Elaborate in more detail here: Good exercise in systematic evaluation of financing decisions Usually avoided by making arbitrary assumptions, you ll get the full Monty (almost) Limited practical use: only 1 imperfection, taxes, can be incorporated in discount rate assume optimal capital structure externally determined (not modelled) 5 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Some important concepts Business risk uncertainty of cash flows generated by firm s assets risk of oil company, software house, construction company Opportunity costs of capital reward for bearing business risk is what shareholder expect if all equity financed set prices such that expected return equals OCC Financial risk if cash flow split in low risk-return and high risk-return part debtholders have priority over shareholders shareholders bear extra financial risk 6 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Discount rates r = r a = opportunity cost of capital expected rate of return for equivalent risk all equity financed assets r = WACC after tax weighted average cost of capital WACC calls for unlevered after tax cash flows WACC is valid for assets with same risk and debt ratio WACC = r e E V + r d(1 τ) D V (1) r d = cost of debt r e = cost of equity, subscript. u,l for (un)levered τ = corporate tax rate (constant, no personal taxes) 7 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Returns equity assets, OCC WACC debt D/E Returns and leverage 8 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Basic approaches When business risk changes: calculate new opportunity cost of capital / new asset β taking leverage into account (unlever βs, example later) remember: proper β is project β (not necessarily company β) When debt ratio increases given business risk, two ways: 1 Adjust the discount rate downwards, to include value of interest tax shields 2 Adjust the present value with side effects called Adjusted Present Value, after Myers 9 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV To calculate Adjusted Present Value: 1 First calculate base case value of project as if all equity financed and without side effects 2 Then separetely calculate value of side effects and sum results. Side effects can be anything: tax shields, issue costs, effects on other projects, agency costs, fees to stock exchange, etc. In case of taxes: 1 first calculate value as if all equity financed 2 then calculate value of tax shields Concentrate on tax shields here, but include some examples of other side effects 10 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Value of tax shields depends on the financing rule followed: 1 Money amounts of debt predetermined, following a schedule 1 repayments and interest follow schedule 2 tax shields tied to interest payments, cost of debt appropriate discount rate 2 Debt rebalanced to a constant fraction of future project values 1 money amount of debt goes up and down with project value 2 tax shields also tied to fortunes of the project incorporate business risk discount at the opportunity cost of capital 11 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Working with APV: some examples Base case Project gives perpetual risky cash flow (EBIT) of 1562.5 per year Requires an investment of 8000 Tax rate is 20%, risk of assets requires a return of 15% r = r a = r e,u =.15 Value of the unlevered cash flows: (1.2) 1562.5 = 1250.15 = 8333 Base case NPV = 8333-8000 = 333 12 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Issue costs Firm issues equity to finance the project Issue costs are 7.5% Has to issue to collect 8000 100 8000 = 8649 92.5 Issue costs: 8649-8000 = 649 APV = 333-649 = -316 13 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Tax shields Project has debt capacity of 50% Take a perpetual loan of 4000, predetermined money amount Interest rate 10%, yearly interest charge 400 Tax advantage interest:.2 400 = 80 Debt fixed: discount at r d value tax shields: 80.1 = 800 Issue 4000 100 92.5 = 4324 in equity, issue costs 324 APV = 333-324 + 800 = 809 14 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV Rebalanced debt What if debt is rebalanced every year? We know the first year s tax shield: 80 Have to discount to present (t 0 ) at r d =.1 At the end of the first year, debt is rebalanced to 50% of project value (unknown now) then second year s tax shield is know: discount year 2 to year 1 (t 1 ) with r d but it is uncertain how project value develops in year 1: discount year 1 to present (t 0 ) with r a : 80 (1 +.15) (1 +.1) }{{}}{{} yr.1 rebal. yr.2 fixed 15 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV At the end of the second year, debt is rebalanced to 50% of project value (unknown now) then third year s tax shield is know: discount year 3 to year 2 (t 2 ) with r d but project value development in years 1 and 2 uncertain: discount year 1 and 2 to present (t 0 ) with r a rebalance debt fixed t=: discount at: 0 r a 1 r a 2 r d 3 time 16 D. van der Wijst Finance for science and technology students

Introduction Basic approaches of APV In formula: 80 (1+.15) 2 (1+.1) or more generally: 80 80 + 1 + r d (1 + r a )(1 + r d ) + 80 (1 + r a ) 2 (1 + r d ) +... Sum of this series calculated in 2 steps: discount at r a, the opportunity cost of capital multiply result by: For our project: 1+r a 1+r d 80 1.15 = 533.15 1.1 = 557 APV = 333 + (- 324) + 557 = 566 17 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) Adjusting the discount rate Structure of the problem is simple: we know the elements on the balance sheet need to express unknown returns as functions of known returns by rewriting the balance sheet equality But: tax shields can have two returns/discount rates gives to sets of functions 18 D. van der Wijst Finance for science and technology students

Starting point is the balance sheet: Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) r a Value assets = V a debt = D r d r d or r a Value tax shields PV(TS) equity = E r e total value = V total value = V If debt is predetermined: risk of tax shields = risk of debt discount tax advantages at r d use Modigliani-Miller formula, MM tax case If debt is rebalanced: risk tax of shields = risk of assets discount tax advantages at r a use Miles-Ezzell formula, MM no-tax case 19 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) (1) Predetermined debt Gives the following balance sheet: r a Value assets = V a debt = D r d r d Value tax shields PV(TS) equity = E r e total value = V total value = V Predetermined debt amounts mean: tax shields just as risky as debt itself discount at r d 20 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) We can write the balance sheet in terms of weighted average costs of capital: r a V a + r d PV(TS) = r e E + r d D (2) Rearranging terms gives expressions for r a and r e : r a = r e E V a + r d D PV(TS) V a (3) V a r a V = r E e V + r D PV(TS) d V 21 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) and for r e : r e = r a + (r a r d ) D PV(TS) (4) E These are general expressions that can also be used for projects of limited life. But they are not very practical: call for the value of tax shields usually not known before project value is calculated except under MM assumption that debt is also permanent 22 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) If debt is also permanent (as well as predetermined), the present value of the tax shields is PV(TS) = τ(r dd) r d = τd (5) Substituting (5) in (3) and (4) gives the Modigliani-Miller expressions for r e and r a : r e = r a + (r a r d ) D PV(TS) E = r a + (r a r d ) D τd E r e = r a + (r a r d )(1 τ) D E (6) i.e. MM proposition 2 with taxes 23 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) and for r a : V a r a V = r E e V + r D PV(TS) d V E = r e V + r D τd d V V a r a V = r E e V + r d(1 τ) D V = WACC = r (7) WACC formula (7) can be re-written in 2 ways: 24 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) 1 Gives an explicit relation between r a and r (exact for fixed and permanent values) V a r a V V τd r a ( V r a 1 τ D ) V = WACC = r = r = r Defining L = D/V, i.e. the debt-value ratio, we get the Modigliani-Miller formula: WACC = r = r a (1 τl) 25 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) MM formula can be used to unlever and relever : given the WACC, formula can be used to calculate r a the opportunity cost of capital in most given situations, r e, r d and τ are (in principle) observable r a is not r a can then be used to calculate WACC for a different debt ratio Modigliani-Miller formula can also be derived by substituting MM prop. 2 (6) into WACC (7) 26 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) 2 Second way to rewrite WACC formula gives alternative expression for r a : D r a = r d (1 τ) V τd + r E e V τd We can do the same analysis in terms of β: β e = β a + (1 τ)(β a β d ) D E D β a = β d (1 τ) V τd + β E e V τd 27 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) Adjusting the discount rate (2) rebalanced debt Continuous rebalancing Gives the same balance sheet as before r a Value assets = V a debt = D r d r a Value tax shields PV(TS) equity = E r e total value = V total value = V 28 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) Continuous rebalancing means: tax shields just as risky as the assets proportion of total value in assets vrs. tax shields irrelevant taxes drop out of the equation opportunity cost of capital is simply the weighted average of the costs of debt and equity: V a r a V + r PV(TS) D a = r a = r = r d V V + r E e V 29 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) Can also be rewritten in terms of r e or β, gives MM prop.2 without taxes: r e = r + (r r d ) D E β e = β a + (β a β d ) D E 30 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) Periodical rebalancing If debt is rebalanced once per period Tax shield over the next period is known: τr d D should be discounted at r d : τr d D/(1 + r d ) Tax shields further in future are uncertain should be discounted with r a Gives following balance sheet identity in return terms: V a r a + τr dd 1 + r d r d }{{} next period + (PV(TS) τr dd )r a = r e E + r 1 + d D r }{{ d } further periods 31 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) Rewriting (using V a = E + D PV(TS)) gives expression for r e : r e = r a + (r a r d ) D E (1 equivalent to MM2 with discrete rebalancing τr d 1 + r d ) (8) Substituting (8) into the formula for the WACC (1) gives (after extensive rewriting): r = WACC = r a D ( ) 1 + V r ra dτ (9) 1 + r d This formula is known as the Miles-Ezzell formula 32 D. van der Wijst Finance for science and technology students

Financing rule 1 (debt predetermined amounts) Financing rule 2 (debt rebalanced) Miles-Ezzell formula equivalent to Modigliani-Miller if debt is rebalanced discretely. Used in the same way for unlevering and relevering: for a given WACC, formula gives r a the opportunity cost of capital given r a formula can be used to calculate WACC for a different debt ratio (and different cost of debt) Formula can also be derived using a backward iteration procedure, start with last period, work way to beginning (as originally done by Miles-Ezzell) 33 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Project values with different debt ratios Recall that this requires business risk to remain the same Method depends on the characteristics of the project Main distinction is whether debt amounts are predetermined or vary with project value Formulas for perpetuities often used for short lived projects Distinction continuous - discrete rebalancing seldom used 34 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Procedure: we know returns: r e and r d and relative sizes: V e /V and V d /V of debt and equity in existing operations: data in bold We also known the firm s financial policy (rebalanced or predetermined debt) the interest rate and D/E ratio for the new project We can then calculate the project value by adjusting the WACC (stepwise or with a formula) or by using APV Graphical representation of procedure: 36 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Returns given for new project inferred from existing operations calculated for new project equity assets, OCC WACC debt D/E Returns and leverage 41 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Procedure looks complicated, rationale is simple: 1 To calculate project value, we need the WACC 2 to calculate WACC, we need cost of equity, r e 3 to calculate cost of equity, we need OCC r = r a 4 OCC can be calculated from existing operations, since business risk is the same So we start at the bottom, with the OCC We also need project details: project s debt ratio (decided by management) project s financing rule (decided by management) project s cost of debt (bank will give an offer) 42 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Debt rebalanced, 3 ways: First way: stepwise adjust WACC (this requires continuous rebalancing): (a) Unlever: calculate opportunity cost of capital from the existing operations D r = r d V +r E e V 43 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined (b) Use this OCC plus project s cost of debt and debt ratio to calculate project s cost of equity using: r e = r + (r r d ) D E step (a) and (b) can be also be done in terms of β s, then use CAPM to calculate returns (c) Relever: calculate after tax WACC using project s costs and weights: WACC = r e E V + r d(1 τ) D V 44 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Second way: adjust WACC using Miles-Ezzell formula (this requires discrete rebalancing): (a) Unlever: use data from existing operations to calculate OCC ( ) r D (1 + r) = r τr d V (1 + r d ) by solving Miles-Ezzell for r (use Miles-Ezzell in reverse ) (b) Relever: use Miles-Ezzell and OCC plus project s cost of debt and debt ratio to calculate project s WACC: ( ) r D (1 + r) =r τr d V (1 + r d ) 45 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Third way: use Adjusted Present Value (APV): 1 Calculate OCC using 1 of methods above 2 discount project s cash flow to find base case NPV 3 Discount tax shields at opportunity cost of capital 4 Multiply PV with (1 + r)/(1 + r d ) if debt is rebalanced periodically 46 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Debt amounts predetermined, same 3 ways: First way: stepwise adjust WACC: (a) Unlever: calculate opportunity cost of capital r = r a : r a = r e E V a +r d D PV(TS) V a V a or r a V = r E e V +r d D PV(TS) V Not very practical, only used under the Modigliani-Miller assumption that cash flows are perpetuities: D r = r a = r d (1 τ) V τd + r E e V τd 47 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined (b) Use OCC and project s cost of debt and debt ratio to calculate project s cost of equity using: r e = r a + (r a r d ) D PV(TS) E or under the Modigliani-Miller assumptions: r e = r + (1 τ)(r r d ) D E step (a) and (b) can be also be done in terms of β s, use CAPM to calculate returns (c) Relever: calculate after tax WACC using project s costs and weights WACC = r e E V + r d(1 τ) D V 48 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Second way: adjust WACC using Modigliani-Miller formula (requires MM assumptions) (a) Unlever: use data from existing operations to calculate OCC r = r a (1 τl) by solving MM for r a (use MM in reverse ) (b) Relever: use MM again, with OCC (r a ) and project s debt-to-value ratio to calculate project s WACC: r = r a (1 τl) MM assumes debt is predetermined and permanent good approximation for projects with limited lives if debt is predetermined 49 D. van der Wijst Finance for science and technology students

Outline Debt rebalanced Debt amounts predetermined Third way: adjusted present value (APV) calculate OCC calculate base case NPV use predetermined schedule for interest payments discount tax shield at the cost of debt 50 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Example of unlevering β : If project is in different line of business: different business risk different asset β different opportunity cost of capital Find asset β from firms in same line of business: take average of a no. of firms after unlevering β s assumes disturbances cancel out. 51 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Following 3 firms are considered representative of business risk (asset beta) in an industry. Calculate the asset beta. Firm Stock β debt/total value 1 1.35 0.40 2 1.25 0.50 3 1.30 0.55 All debt is rebalanced and can be considered risk free. The relation between asset β and equity beta is: if debt is risk free, this is: D β a = β d V + β E e V β a = β e E V 52 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice The calculation becomes: Firm Stock β equity/total value Asset β 1 1.35 0.60 0.810 2 1.25 0.50 0.625 3 1.30 0.45 0.585 sum 2.020 Gives an average β of 2.02/3=0.67 53 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice A worked out example company data Transport company, book value 90 million debt frequently adjusted and renegotiated capital structure constant (rebalanced) market value short term debt 20 mill., interest rate = 9% market value long term debt 20 mill., interest rate = 11% 10 million shares outstanding, priced at 6 to give 20% return tax rate 35% 54 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Balance sheet ZXco Property, plant & eq. 40 Equity 40 other fixed assets 20 Long term debt 20 total fixed assets 60 Accounts payable 10 Cash 10 Short term debt 20 Account receivable 10 current liabilities 30 Inventories 10 current assets 30 total assets 90 total liabilities & equity 90 55 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Project data expansion to new geographical area, same business expansion has optimal capital structure at 60% debt apart from that financial policy unchanged debt available at 12% investment 50 million gives perpetual after tax cash flow of 7 million per year Question: should company accept project or not? 56 D. van der Wijst Finance for science and technology students

Analysis Example of unlevering beta: A worked out example Use in practice When should project be accepted? Accept project if NPV > 0 What do we need to calculate NPV? Proper discount rate or APV Does project have different business risk? No, expansion in same business, same risk Can we use company cost of capital (WACC)? No, business risk is the same, financial risk is different, different debt ratio What procedure do we use? Debt rebalanced stepwise adjust WACC, Miles-Ezzell formula or APV 57 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Calculations First, make some adjustments to balance sheet: 1 Calculate company capital structure at market prices: Market value debt 40 million (20+20, freq. renegotiated) Market value equity 6x10 million = 60 mill. 2 net out accounts payable and current assets accounts payable bear no interest net working capital on left hand side keep interest bearing short term debt on right hand side 58 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Balance sheet s right hand side becomes: Gives a company WACC of: Equity 60 Long term debt 20 Short term debt 20 total 100 WACC = (1.35).11.2 + (1.35).09.2 +.2.6 =.146 Miles-Ezzell calls for 1 cost of debt, use weighted average:.5.11 +.5.09 =.1 We can use APV or find discount rate for project with 1 of the 2 methods 59 D. van der Wijst Finance for science and technology students

First method: stepwise adjust WACC (this assumes continuous rebalancing): Example of unlevering beta: A worked out example Use in practice 1 Unlever: use data ZXco s existing operations to find OCC: D r = r d V +r E e V 40 60 =.1 +.2 100 100 =.16 2 use OCC and project s cost of debt (.12) to calculate project s cost of equity: r e = r + (r r d ) D E =.16 + (.16.12)30 20 =.22 3 relever: calculate project s WACC: WACC = (1.35).12.6 +.22.4 =.1348 or 13.5% 60 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Second method: use Miles-Ezzell (this assumes discrete rebalancing): 1 Unlever: use ZXco s data to find OCC r: ( ) r D (1 + r) = r τr d V (1 + r d ) ( ) (1 + r).146 = r.35.1.4 r =.161 (1 +.1) 2 Relever: find project s WACC using OCC and project s r d and L : r =.161.35.12.6 ( 1.161 ) =.1349 or 13.5% 1.12 61 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Value of perpetual cash flow of 7 with discount rate of.135 is 7/.135 = 51.85 investment is 50, NVP = 1.85 > 0 Project should be accepted 62 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice Third method: use APV: 1 First calculate base case as if all equity financed using opportunity CoC: 7/.16 = 43.75 2 Then calculate tax shield: τr d D =.35.12 30 = 1.26 (D =.6 50) 3 Discount at opportunity CoC: 1.26/.16 = 7.875 4 Multiply PV with (1 + r)/(1 + r d ) : ((1 +.16)/(1 +.12)) 7.875 = 8.16 5 Total APV is 43.75 + 8.16 = 51.91, NPV is 1.91, same conclusion: accept project 63 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice If the project would be financed with a perpetual loan with the same interest rate but predetermined amounts instead of the flexible loan used now would the value of the project go up or down? (no calculations necessary) same interest same tax advantage but fixed safer lower discount rate (r d instead of r) so higher project value 64 D. van der Wijst Finance for science and technology students

Example of unlevering beta: A worked out example Use in practice What methods are use in practice? We have already seen 1 answer: Capital structure shows (slow) mean reversion means debt ratios are rebalanced Found on a much wider scale: most firms have target debt ratios or a target range for their debt ratio Rebalancing is dominant financial policy WACC is extensively used in practice, together with CAPM 65 D. van der Wijst Finance for science and technology students
