3 Background What is capital structuring? Process of interchanging debt, equity and assets Why is it important? Enables one to optimize the value of a firm or its WACC by finding the best mix for the amounts of debt and equity on the balance sheet. Provides a signal that the firm is following proper rules of corporate finance to improve its balance sheet. This signal is central to valuations provided by market investors and analysts. Who is interested in it? Academics, because it is controversial and open ended Practitioners, because they use it for valuation, advisory and development and marketing of financial products & strategies 3

7 2. The Modigliani-Miller (M&M) Theorems Motivation & Methodology 7

8 Motivation Key Observation 1 EBIT [ EBIT Operating Income R D D ](1 T ) = or R (1 T ) = R D D (1 T ) + To debt holders E E R E E To equity holders Balance Sheet Firm s Value, D+E Income Statement EBIT Debt, D Equity, E Tax EBIT x (1-T) What if T = 100%? Discounted value of cash flows to bond and equity holders will be zero. Therefore, value implicit within IS will be ZERO! Does not match the firm s value of E + D from the BS. 8

9 Motivation Key Observation 2 Income Statement EBIT (1 T ) = R D D (1 T ) + EBIT R E E Tax EBIT x (1-T) R D D(1-T) R E E D(1-T) E Total Discounted Value derived from Income Statement 80 x (1-40%) + 52 = 100 Effectively, a capital of 100 is being used to operate a firm that s worth 132! Notion of efficiency appears in the ratio 100/132 9

10 Theory Key observations create a need to: 1. Reconcile the difference in valuations between the IS and the BS 2. Exploit the notion of efficiency in capital structure M&M achieves the 2 objectives Main assumptions - Aside from the typical, there are 3: 1. Simple corporate firm able to freely exchange generic debt, equity and assets 2. EBIT & Tax rate held constant as firm exchanges debt, equity and assets 3. No default risk, so that credit spread = 0 at all levels of leverage 10

11 The M&M Methodology Simplistic Derivation Income Statement Expected EBIT 20 Interest (at 5%) 4 EBT 16 Tax (at 40%) 6.4 Expected profit 9.6 Balance Sheet Assets 132 Debt 80 Equity 52 Total Debt & Equity 132 Income Statement Tax Paid EBIT EBIT x (1-T) R D D(1-T) R E E Total Discounted Value derived from Income Statement D x (1-T) + E operating capital 11

12 The M&M Methodology Proposition I Value implicit in the IS = D x (1-T) + E ( operating capital ) Total Firm s Value (FV) = D + E Reconciling Difference = D x T This difference is attributed to tax and debt. Leads to M&M s Proposition I In the absence of taxes, there are no benefits, in terms of value, to increasing leverage. In the presence of taxes, such benefits, by way of the interest tax shield, do accrue when leverage is introduced and/or increased. Could be exploited to increase the efficiency of the firm e.g. increase Tax, Debt or the product DT. Tax is difficult to control, but debt could be increased. 12

13 Operating capital The M&M Methodology Proposition II If FV = D + E And the value added due to debt = D x T Then the remainder, D x (1-T) + E, must represent the unlevered value of the firm and is a constant, equal to E 0 = V U Recall: EBIT(1-T) = R D D(1-T) + R E E R U EBIT(1 T ) D(1 T ) + E = RDD(1 T ) D(1 T ) + E + REE D(1 T ) + E Defining φ = D/E & solving for R E gives M&M s Proposition II R E = R U + ( R R )(1 T )φ U D 13

14 The M&M Methodology in Practice Creating the FV Curve Step 1 Question: Consider the firm has D = 80 and E = 52. It wants to issue enough equity to buy back all debt and completely delever. How is this done according to M&M? Answer: We know ΔV = D x T = 80 x 40% = 32. Therefore to delever completely, the value of the allequity firm should be = 100. Achieved by issuing 48 in equity and selling off 32 in assets, totalling 80 - enough to buy back all debt. 14

15 The M&M Methodology in Practice Creating the FV Curve Step 2 Question: The firm is now fully debt free. It wants to borrow 20 to buy back some of its shares and, at the same time, purchase some assets. How is this done according to M&M? Answer: We know ΔV = D x T = 20 x 40% = 8, which raises the firm s value from 100 to 108. Therefore, with additional debt of 20 buy back 12 in equity and purchase 8 in assets. 15

16 The M&M Methodology in Practice A More Methodical approach Begin with the original financial statement Create table similar to the one below 1. Insert debt in increments 2. Populate with information that s readily available 16

17 The M&M Methodology in Practice A More Methodical approach Define WACC EBIT (1 T ) D + E = EBIT (1 T ) V + DT U ROE = Profit E and populate relevant cells 17

18 The M&M Methodology in Practice A More Methodical approach Calculate parameters for D = 0 Recall: at D = 0, all equity firm value E 0 = E + D(1-T) = *(1-40%) = 100 Insert in the appropriate row 18

19 The M&M Methodology in Practice A More Methodical approach Recall E+(1-T)D = 100 across all debt levels i.e. at D=20, E = 100-(1-40%)*20 = 88; D=40, E = 100-(1-40%)*40 = 76, etc. Streamline and automate the process * to finally populate all cells at different increments of D * If preferred, this could be done using the beta approach (Hamada s Equation). Either way, the results must be identical 19

24 What is Beta? Defined as: β It is a measure of relative risk It depends on leverage. This comes through R E To obtain beta, plot R E - R f vs R M - R f Slope of fitted straight line is the beta Beta turns out to be independent of R f L R R E M R R f f Market risk premium 24

38 4. Default Risk and Credit Rating Methodologies 38

39 Credit Risk and Credit Spread Some Facts The interest rate at which corporations can borrow money depends on the market s perception of the probability that they will not be able to pay back the debt. The premium for this rate above the risk-free interest rate is known as the credit spread. The credit spread, a direct measure of credit risk, is linked to the probability of default the recovery rate and The term of the loan The classification of credit risk into bands is known as credit rating. The banding follows AAA, AA, A, BBB, BB, B, CCC, CC, C and Default. Pluses and minuses are, in addition, used to add granularity within the different bands (i.e. A+, A-, etc.). 39

40 Credit Rating Models Credit agencies, the primary ones being S&P, Moody s and Fitch, use credit rating models to assess a firm s credit worthiness. These ratings are then binned into categories tabulated below: Rating Investment Grade Financial Capacity AAA Yes Extremely Strong AA Yes Very Strong A Yes Strong BBB Yes Adequate BB & No Weak CRM s are generally complex and inputs to them are both statistical and subjective, involving historical, as well as forward-looking, elements 40

41 Assessing the Risk of Default Different Credit Rating Methodologies There are three main classes of quantitative CRM s, which are used most widely. They are derivatives of: Ratio-driven models S&P Fitch Z Score Merton model There are also other types, which are hybrids 41

56 Z-Score Model Implementation Historical Statistics show that for manufacturers, non-manufacturer industrials, and emerging market credits the following relationship holds within reason: Z = 6.56X X X X 4 56

57 Z-Score Model US Bond Rating Equivalent Based on Z Score Model 57

58 Merton s Model Question: Borrow $D today to start a business. Interest is paid throughout the year and the loan is to be paid back at the end of one year. If the business were to sell its assets after one year to pay off the loan, would the amount be sufficient to cover it ( $D)? Portrayed as: Asset Volatility Today One year from today Similarity to option-pricing concept: Debt obligation strike price Asset market value & volatility Share price & volatility Probability of default Area under curve behind D 58

59 Comparison Ratios/Scoring Need calibration Incorporate more variables More dependent on historical information Probability of default computed indirectly Appear to involve more steps to get to the rating Heavy dependence on financial statement inputs More easily applied to private firms. Merton May not need calibration Incorporates less variables Less dependent on historical information Probability of default computed directly Less steps and more direct Involves primarily market variables Difficult to apply to private firms. 59

61 5. Incorporating Default Risk 61

62 Impact of Default Risk on Capital Structure Incorporation into the Model and Optimization of Capital Structure 62

63 Impact of Default Risk 1. Leads to credit spread 2. Gives an optimal capital structure 3. Idea: tax benefits and default risk work against each other, taking FV-vs-leverage curve through a maximum or the WACC through a minimum 4. Approach identical to classical M&M, but must take into account the credit spread due to default risk 63

64 Optimization of the Capital Structure 1. Objective is to locate the optimal capital structure 2. By classical definition, minimum WACC is where the optimal capital structure occurs 3. Recall: WACC EBIT (1 T ) D + E 4. Since EBIT x (1-T) = constant by assumption, then max(e + D) and min(wacc) occur at exactly the same leverage 5. The rest is based on the principle of maximizing the firm s value rather than minimizing the WACC 64

65 Procedure Requirements 1. Need a credit-rating model to calculate credit spreads along the curve Can use any This work utilises the S&P approach, which is based on ratios 2. Important to recall that D * x (1-T) + E = constant was derived based on the default-free scenario (classical M&M), where D * is the default-free debt 3. Must accordingly adjust the BS debt when there is credit risk. Adjustment of the form: * R D = D D R * D 4. With this adjustment, procedure becomes identical to classical M&M s 65

76 Important Relationships Recall β L R R * + β R D E Hamada Equation U [ 1 (1 )] * + T = β φ L P Valid only when interest rates are constant, independent of leverage. Therefore, must modify D/E to account for credit spread. WACC = RE RDφ(1 T ) + 1+ φ 1+ φ 76

92 9. Applying Constraints 92

93 Applying Constraints To get to the OCS (max FV) from current, issue 43 units in E to buy back 32 units of debt and purchase an additional 11 of assets. Question: What if no suitable assets were available for purchase or there was a preference instead for a 1:1 share buy back? Constrains the firm to follow FV = const. This moves the firm on the FV curve, along which V U = const, towards the OCS. With no apparent maximum in the firm s value, how is the optimal capital structure determined??? 93

94 Finding the OCS under Constraints Every point along the E+D = const. line will have a unique V U associated with it (because V U varies with leverage) Obtain the locus of V U s and the OCS falls where the ratio V U /FV is minimised FV = constant 120 Vu min Vu 110 Unique unlevered values associated with each FV Leverage, D/E point

95 Finding the OCS under Constraints OCS occurs at min V U /FV FV = constant FV = E + D OCS OCS Ratio Vu/FV

96 On the Side Recall From Part 2 (derivation of classical M&M) EBIT x (1-T) operating income R D D(1-T) R E E Total Discounted Value derived from Income Statement D x (1-T) + E operating capital = unlevered value = V u Outcome: operating income operating capital i.e. EBIT(1-T) = R u V u where R u is a proportionality constant (see Part 2) 96

97 On the Side Implications on the S&P CRM The S&P CRM contains ratios that involve the EBIT EBiT interest cover and D-to-EBITDA, among others Therefore in constrained cases, where V u varies with leverage, one must take into account the impact of this variation on the EBIT. Once this is accounted for, the ratios containing EBIT and EBITDA could subsequently be adjusted. Output EBITDA, EBIT, D, E, T, CRM spread V u Until convergence 97

98 Finding the OCS under Constraints Possible Scenarios 1 & 2 Scenario 1: Firm wants to follow Vu = const = 130, as per M&M s methodology. Scenario 2: The firm wants to keep the equity level constant at 52 and exchange debt with assets (raise debt to buy assets or sell assets to buy back debt. D/E=154% D E Vu V D/E=51% D/E=92% 98

99 Finding the OCS under Constraints Possible Scenarios 3 & 4 Scenario 3: Firm wants to follow FV = const = 132 by exchanging debt for equity and vice versa at 1:1. Scenario 4: The firm wants to keep the debt level constant at 80 and exchange equity with assets (issue equity to buy assets or sell assets to buy back equity. D/E=57% D/E=51% 99

167 11. Depository Institutions 167

168 Depository Institutions Seeking the Optimal Capital Structure 168

169 Depository Institutions A depository (or lending) institution is a simple bank that generates revenues from lending the assets on its BS. Tax Step1: R D D Step2:R E E Depositor/ Bond Investor D Depository Institution E Equity Investor D+E R T [D+E] Counterparty (Borrower) Income Statement Operating Income (at 5% of assets) 10 Interest paid (at 4%) -6 EBT 4 Tax (at 40%) -1.6 Net Profit 2.4 Balance Sheet Total Assets 200 Debt 150 Equity 50 Debt + Equity 200 Ratios Leverage, D/E 3 ROE, Net Profit/Equity 5% 169

170 Depository Institutions Main Differences with Corporate Firms Significantly more complicated than corporate firms because: Two entities, rather than one, are subject to credit/default Risk The Bank (as borrower from investors/depositors) and the Counterparty (as borrower from the Bank). The operating income (EBIT) of the bank is not constant, but varies with the size of its BS There are limits to lending In order to protect depositors and investors, banks cannot lend to the third party only what they borrow. A pre-determined amount of the money lent out must be equity. This amount of equity is dictated by certain regulatory capital ratios, determined by the borrower s risk rating and the size of the bank s BS. Above limitations create strong interdependence between bank and borrower 170

171 Depository Institutions M&M Treatment of a Simplified Financial Statement Income Statement Operating Income (at 5% of assets) 10 Interest paid (at 4%) -6 EBT 4 Tax (at 40%) -1.6 Net Profit 2.4 Balance Sheet Total Assets 200 Debt 150 Equity 50 Debt + Equity 200 Ratios Leverage, D/E 3 ROE, Net Profit/Equity 5% Operating income EBIT = R T (D+E) Interest expense = R D D Profit = R E E = [R T (D+E) - R D D] (1-T) EBIT(1 T) WACC = RT (1 T) = const. E + D IS Value = = R ( 1 T) + [ R R ] (1 T) φ R R T E T ( D + E)(1 T ) RDD(1 T ) = α R T D D REE + R E 171

172 Depository Institutions Fundamental Relationships R E = R ( 1 T ) + [ R R ] (1 T ) φ T T D Form of M&M s proposition II is preserved. EBIT (1 T ) WACC = RT (1 T ) = const E + D Inverse proportionality relation between WACC & FV is lost. R ( D + E)(1 T ) RDD(1 T ) RE E T = + = D(1 T ) E α R R + R T ( 1 T ) D(1 T ) E Tφ = const = + = 1 α D + E D + E 1+ φ D E Fundamental constant in this case is D/E, instead of D(1-T)+E 172

173 Depository Institutions Limitations To protect depositors/bond investors from borrowers risk, a bank s BS must adhere to certain limitations imposed on some of its financial ratios. Limitations are known as Regulatory Capital and the ratios involved are called Tier 1, Tier 2, etc., going down in order of importance. These are used to describe the capital adequacy of the bank and ensure that capital allocation is risk sensitive. Tier 1 capital is the core capital, which includes equity capital and disclosed reserves. Tier 2 capital is the secondary bank capital. It includes items such as undisclosed reserves, general loss reserves, subordinated debt, and more. These restrictions make the bank and borrower highly interdependent on each other and, thus, significantly complicate the analysis. 173

174 Depository Institutions Possible Cases Recall: EBIT (1 T ) WACC = RT (1 T ) = E + D const R E = R ( 1 T ) + [ R R ] (1 T ) φ T T D Case R T R D I Constant Constant Out: R D II III Constant Variable Variable Constant Depository Institution In: R T IV Variable Variable 174

175 Depository Institutions Case I - R T & R D constant R D Depository Institution R T 20% Ideal - Case i 10% R E 0% Leverage, φ = D/E WACC % 175

176 Depository Institutions Case II R T constant, R D variable with φ R D Depository Institution R T 20% 10% 0% -10% Return on Equity, RE Leverage, φ = D/E

177 Depository Institutions Impact of the Tier 1 Capital Restriction Definition - Tier 1 capital is the core capital. It includes equity capital and disclosed reserves. This is assigned a maximum limit of typically 8%. Applied to the simplified financial statement of a lender, lending assets E + D to a single borrower: T 1 E RWA = E r ( E + D) = 1 r (1 +φ) RWA = risk weighted assets r = risk weighting of borrower 177

178 Depository Institutions Relationship Between r and R T With T 1 = constant, above may be written as: r = 1 as φ T (1 + φ), r 1 Recall: r is the borrower s risk weighting. Therefore, as r, R T Combining: as φ, R T 178

179 Depository Institutions Case III R D constant, R T variable as φ R D Depository Institution R T 20% 10% (III) (I) (II) 0% -10% Return on Equity, RE Leverage, φ = D/E

180 Depository Institutions Case IV R D variable as φ, R T variable as φ R D Depository Institution R T 20% 10% (III) (I) (II) (IV ) 0% Return on Equity Leverage, φ = D/E % 180

181 Depository Institutions Case IV Impact of T 1 20% 4% Tier 1 = 4% Tier 1 = 8% Tier 1 = 12% 10% 8% 12% 0% -10% Return on Equity, RE Leverage, φ = D/E

182 Depository Institutions Where is the Optimal? Consider the most realistic case, being Case IV, where R D as φ and R T as φ : WACC is a decreasing function of leverage, φ. Note that not all T 1 s have a max at some finite leverage. Note that max R E does not coincide with min WACC. Etc., etc.,... 8% 6% R E 4% WACC 2% 0% Leverage, φ = D/E

183 Conclusions Reasons for complications Lender s risk Borrower s risk Interdependence between the two Discussed different scenarios Concluded that there is no straightforward way to define the OCS 183
