Capital Structure
2. Foundations of capital structure
Originated with Modigliani and Miller (1958)
Impact of capital structure on firm value (DCF)
Increasing cash flows
Decrease WACC
Model developed in three stages
Without taxes and bankruptcy costs
With taxes but without bankruptcy costs
With taxes and bankruptcy costs M&M Theory
3. Impact on Cash Flows
Capital structure does not affect value of firm.
Financing decision vs. Investment decision
Impact on WACC
WACC constant regardless of capital structure.
If firm increases debt
Risk to shareholders increases
They demand higher returns
Increased RE offsets D/E change and WACC unchanged.
M&M Case I
4. Impact on Cash Flows
Tax gives rise to interest tax shield benefit.
Tax shield benefit increases linearly with debt taken on.
VL = VU + Tc x D
Impact on WACC
Cost of debt (RD) is interest payable on debt.
RD reduced due to govt. subsidy on interest payments.
Taking on debt therefore reduces WACC.
Therefore optimal debt is 100%.
M&M Case II
5. Why is 100% debt not observed in practice?
Debt increases risk of bankruptcy
Bankruptcy destroys firm value
As we take on debt we
Increase firm value due to interest tax shield benefit
But also increase cost of bankruptcy.
Optimal capital structure
Occurs where tax shield exactly offset by bankruptcy costs
Beyond this point costs of debt outweigh benefits
Essentially trade-off between tax benefits of debt and costs of bankruptcy (Static Trade-Off)
M&M Case III
6. Taxes:
Tax benefit from leverage only important to firms in a tax-paying position (i.e. Profitable)
Firms with substantial tax shields from other sources (e.g. Depreciation) receive less benefit.
Not all firms have same tax rate. Higher tax rate, greater incentive to borrow.
Important Conclusions
7. Financial Distress:
Firms with greater risk of financial distress will borrow less than those with less risk.
Typically measure risk through volatility of PBIT.
Financial distress also more costly to some firms than others depending on assets.
Firms with mostly tangible assets can dispose of them more easily and cost-effectively than those with intangibles.
Important Conclusions
8. Critics contend M&M flawed once real world issues introduced.
Perhaps our model needs to be extended?
Previously only considered debt and equity for determining firm value.
Various stakeholders have claim to cash flow of firms, however (e.g. government for taxes, potential bankruptcy costs, environmental groups, etc.)
All of these can only be paid from cash flows of firm.
M&M Theory Now
9. Marketable versus Non-marketable Claims
Marketable claims can be bought and sold in financial markets (e.g. Debt and equity)
Non-marketable claims cannot (e.g. Taxes, bankruptcy costs)
Firm value is thus sum of marketable and non-marketable claims
Therefore cannot alter firm value by changing capital structure.
Capital structure is important, however, because it determines split between marketable and non-marketable claims.
Goal is to maximise marketable claims while minimising non-marketable claims. M&M Theory Now
10. Managers versus Shareholders
Agency problems arise between shareholders and management where manager equity stake in firm is low.
More equity management holds, less agency conflicts likely.
If we hold absolute equity stake of management constant, taking on debt increases their relative holdings in firm and reduces conflict between managers and shareholders.
Debt can therefore be used to mitigate agency problems.
Agency Theory
11. Harris and Raviv (1990):
Firms with higher liquidation values more likely to have debt and more likely to default as a result.
Such firms will have higher market value than similar firms with low liquidation value and higher investigation costs.
Stulz (1990):
Optimal is trade-off between benefit of debt (preventing investment in value-decreasing projects) and costs of debt (preventing investment in value-creating projects)
Firms with many good investment opportunities therefore likely to have less debt than those in mature, slow-growth industries. Managers versus Shareholders
12. Debt contracts have limited upside
Equity captures gains
Debt may bear losses
Over-investment by firms near bankruptcy
Debt-holders bear the consequences
High risks can be taken
Even negative NPV projects may be attractive
Selection of high risk projects
Shifting risk erodes firm value (& debt value)
Value is transferred from debt holders to equity holders
Known as “asset substitution”
Shareholders versus Debtholders
13. Problems may be anticipated by lenders
Higher interest charges
Equity holders may counter by offering covenants
Underinvestment by firms near bankruptcy (Myers, 1977)
No incentive for equity holders to invest even in good projects
Likely that benefit of gains will accrue to debtholders
Larger debt levels may lead to rejection of value-adding projects
Shareholders versus Debtholders
14. Diamond (1989)
Firms have incentive to pursue safe projects
Debtholders dislike firms with history of risky investments
Build history of safe investments for best lending terms
May be incentive for small firms to take on risky investments early in life
If they survive without defaulting, will eventually switch to safe projects
Therefore likely that younger firms have less debt than older ones
Shareholders versus Debtholders
15. Hirshleifer and Thakor (1989)
Management reputation may also hinge on safe investments
Managers focused on success versus returns
May select project that has highest probability of success even if it won’t provide highest return to equity holders
Such firms lend themselves to favourable debt terms and likely to have higher amounts of debt
Shareholders versus Debtholders
16. Managers possess private information re firm’s opportunities
Capital structure decisions therefore sends signal to market re private information (Ross, 1977)
Can also be used to limit inefficiencies in investment decisions due to information asymmetries (Myers and Majluf, 1984)
Assymetric Information
17. An equity issue
Good news (+ve NPV projects)?
Bad news (shares overvalued)?
Discount share price!
A debt issue
Share prices don't fall - convey more positive news
Management feels they can service new debt
Asymetric Information
18. Ross (1977)
Managers possess more information on firm than market
Managers benefit if equity value increases
Managers penalized if firm goes bankrupt
Investors take high debt levels as sign of quality
Low quality firms have higher marginal costs of debt and therefore issue less debt
Signalling
19. Ross (1977)
Finds that firm value and D/E ratio positively related
However, greater debt also increases bankruptcy costs
Quality firm able to accommodate costs of debt, however.
Managers can therefore use debt to signal firm quality and improve firm value
Signalling
20. Myers and Majluf (1984)
If investors less well-informed than insiders about value of firm’s assets then equity may be mispriced in market
Assume firm issuing equity to finance new project and severe underpricing occurs
New shareholders effectively received discount on investment while price of existing shares drop
Therefore receive greater net return than they should have at expense of existing shareholders
Existing may have captured more return if debt used instead of equity
Avoid this by issuing security not undervalued by market (e.g. Debt) Investment and Capital Structure
21. Conclusion (Myers and Majluf, 1984):
Possibility of mispricing dictates capital structure decisions
Firms always issue less undervalued assets first
Typical order is:
Internal funding (retained earnings)
Low-risk debt
Equity
Theory referred to as ‘pecking order’
Investment and Capital Structure
22. Brennan and Kraus (1987)
Dispute pecking order theory of Myers and Marjulf (1984)
Conclude firms do not necessarily have preference for debt before equity
Entirely possible that for some firms debt is more risky and cost of repayment is higher than underpricing cost of equity
Some firms therefore prefer debt before equity
Investment and Capital Structure
23. Booth (2001):
Factors influencing capital structure decisions similar across developing and developed markets regardless of significant differences in financial environments
Find that firms with good profits tend to have less debt (pecking order)
Also significant information asymmetries exist making external financing potentially expensive.
Also support for impact of asset intangibility on debt levels. The Financial Environment
