Capital Structure Flashcards
Define capital Structure
capital structure is the mix of securities used by a company to finance it’s operations
Explain why the cost of debt finance is generally lower than the cost of equity finance
- There is less risk associated with debt finance (in the event of financial distress debt holders are paid first)
- Arrangement fees are less for debt issuance than equity issuance
- interest payments are a tax deductible expense
Drawbacks of using lower cost debt to reduce capital costs instead of equity.
- Increasing debt raises default risk and bankruptcy risk
- increased bankruptcy risk causes shareholders/debt-holders to demand greater returns
- Flexibility Loss: More debt can limit company’s operational flexibility e.g. miss investment oportunities due to repayment obligations
Define irrelevancy theory
- Modigliani, Miller 1958,
- Premise: in perfect markets, the value of a firm is unaffected by its capital structure.
Outline the key assumptions of irrelevancy theory
- No taxes
- Individuals and companies can borrow unlimited amounts at the same rate of interest
- No transaction costs
- Personal borrowing is a perfect substitute for corporate borrowing
- Firms exist with the same business risk but different levels of gearing
- All projects, cash flows and debt relating thereto are perpetual
- income generated by the company confirms the company’s value
Outline the propositions of Modigliani miller 1958
- The Market value of any firm is independent of its capital structure
- The expected rate of return on equity in a geared firm is proportional to it’s D/E ratio
Define the traditional approach
- Premise: an optimal debt-to-equity ratio exists where the cost of capital is minimized and firm value is maximized
- Initially, more debt lowers capital costs (due to tax benefits), but past a certain point, costs increase due to higher financial risk.
What does the optimal capital structure mainly depend on (Traditional Approach)?
The business of a specific firm, i.e. if a firm has volatile profits it should have low gearing
Summarise Modigliani, Miller 1963
- Revised version of irrelevancy theory, now includes corporation tax
- Interest payments are tax deductible
- A geared firm is technically more valuable than an identical ungeared firm because tax bill is reduced
- A firms value is maximised by taking on as much debt as possible
How do you calculate the value of a tax shield? (MM63)
Tax shield = r ate of debt * amount of debt * corporate tax rate
how do you calculate the value of a geared firm? (MM63)
Value of geared firm = Value of un geared firm + PV of tax shield PV of tax shield = Amount of debt * corporation tax
MM63 Proposition 3
- Proposition 3: The WACC declines as gearing increases
MM63 Proposition 1
- Proposition 1: The value of a firm is increased as debt is added to the capital structure (optimal capital structure is when debt is maximised)
MM63 Proposition 2
- Proposition 2: As gearing increases, the cost of equity rises at a slower rate than in MM58 due to tax shield benefits.
- This assumes all firms gain from tax shields, in reality, some do not e.g. loss-making firms
Key limitations of Modigliani, Miller 1963
Does not take into account:
- Costs of financial distress (as companies take on more debt they are likely to become more financially distressed)
- personal taxes
Define Trade off theory
According to trade off theory:
- Any tax advantage of using debt is eventually outweighed by expected bankruptcy costs
- implies there is an optimal capital structure
How do you calculate the value of a geared company using trade off theory?
value of geared company = value of ungeared company + (corporate tax rate * amount of company debt) - expected value of bankruptcy costs Vg = Vu +(tc *D) - E(PV(bc))
what is the empirical evidence on signalling theory
- empirical evidence is weak in support of signalling theory
- signalling theory predicts undervalued companies have higher gearing ratios than overvalued companies
- research supports the opposite: gearing ratios are inversely related to profitability
- signalling theory predicts growth firms or firms with high tangible assets would have higher gearing ratios, empirical evidence shows the opposite.
Why is there a preference for debt over equity?
- James 1987 found that share prices typically rise when firms announce bank debt borrowing but fall with equity issuance
- this suggests information costs are higher for equity than for debt
- Gives Rise to pecking order Theory
Define pecking order theory
- Myers Majiluf 1984
- premise: firms financing follows the path of least resistance, in the order:
1- Internal funds
2- debt
3- equity - suggests there is no optimal capital structure
- tax shields and financial distress costs are a second order concern
Define financial slack
having cash or other liquid assets (including unused debt capacity) readily available
Reasons for firms having financial slack
- investment Opportunities: Ensures funds are available for promising projects or investments
- Strategic Flexibility: Allows for quick exploitation of new opportunities without the need to secure external financing
- Internal Financing: Reduces reliance on external capital markets, lowering transaction costs
Problems with too much financial slack
- best discussed by Jensen (1986)
- incentives for managers to exploit free cashflow
- i.e. managers giving themselves higher wages/bonuses
- Managers engage in empire building
solution to financial slack problems
- Jensen (1986) posits that cash-rich companies should increase debt levels to limit free cash for managers, using debt as a control mechanism
- However Jensen overlooks the costs of excessive debt, which can lead to financial distress

What is business risk?
business risk is the variability of operational profit
list Theories of Capital Structure
- Modigliani Miller 1958
- Traditional Approach
- Modigliani Miller 1963
- Trade off theory
- Signaling Theory
- Pecking order Theory
Information Asymmetry and Capital Structure
- Companies communicate internal information and future prospects through their financing choices
- Debt Financing signals confidence in future cash flows, implying managers believe regular interest payments are manageable (increases share price)
- Equity Financing signals that managers lack confidence in future earnings, and or believe shares are overvalued (decreases share price)
information asymmetry in finance
- managers have more complete or accurate information about the company
Signaling Theory
- Based on Information Asymmetry
- Capital Structure depends on whether management believe company is over or under valued
- undervalued companies issue debt to try to increase the value of equity through credible signal
- overvalued issue equity, to lower gearing ratio and financial distress risk
