Capital Structure
Capital Structure refers to the combination of mix of debt and equity
which a company uses to finance its long term operations.
Capital Structure
proportions or combinations ofequity share capital, preference sharecapital, debentures, long-term loans,retained earnings and other long-term sources of funds in the totalamount of capital which a firmshould raise to run its business
Capital Structure
“Capital structure refers to the mix oflong-term sources of funds, such as,debentures, long-term debts,preference share capital and equityshare capital including reserves andsurplus.”—I. M. Pandey.
Capital Structure vs. Financial Structure
• Capital structure is defined as the amount of, long-term debt and common equity used to finance a firm.
• Financial structure refers to the amount of total current liabilities, long-term debt, preferred stock, and common equity used to finance a firm.
Example of Capital StructureLong term debt is LKR. 30,000Equity Share Capital is LKR. 70,000Pref. Share Capital is LKR. 10,000Retained Earnings are LKR. 5000-------------------------------------Total Long term Fund = LKR. 115000============================

Capital structure and value of the firm
• The value of a firm is defined to be the sum of the value of the firm’s debt and the firm’s equity.
V = B + S
• If the goal of the firm’s management is to make the firm as valuable as possible, then the firm should pick the debt-equity ratio that makes the pie as big as possible.
Value of the Firm
S BS BS BS B
Importance of Capital Structure:
• Enables one to “optimize” the value of a firm or its WACC by finding the “best mix” for the amounts of debt and equity
• 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
Optimal Capital Structure
Capital structure or combination of debt and equity that leads to maximum value
of firm.
Maximises value of company and wealth of owners.
Minimises the company’s cost of capital.
Capital Structure Terminology
• Optimal capital structure
– Minimizes a firm’s weighted average cost of capital
– Maximizes the value of the firm
• Target capital structure
– Capital structure at which the firm plans to operate
• Debt capacity
– Amount of debt contained in a firm’s optimal capital structure
Planning the Capital Structure –Important Considerations
Return: ability to generate maximum returns to the shareholders,
i.e. maximize EPS and market price per share.
Cost: minimizes the cost of capital (WACC). Debt is cheaper than
equity due to tax shield on interest & no benefit on dividends.
Risk: insolvency risk associated with high debt component.
Control: avoid dilution of management control, hence debt
preferred to new equity shares.
Flexible: altering capital structure without much costs & delays, to
raise funds whenever required.
Capacity: ability to generate profits to pay interest and principal.
Factors Affecting Capital Structure:
• Business Risk
• Tax structure: Debt’s tax deductibility
• Ability to raise capital under adverse terms
• Managerial decisions Business risk of the firm
• Extent of potential financial distress (e.g., bankruptcy)
• Agency costs
• Role played by capital structure policy in providing signals to the capital markets regarding the firm’s performance
• Government and other regulations

What are the risks associated with capital structure decisions?
• Meaning of risk : variability in income is called risk.
• Business risk = it is the situation, when the EBIT mayvary due to change in capital structure. It isinfluenced by the ratio of fixed cost in total cost. Ifthe ratio of fixed cost is higher, business risk is higher.
• Financial risk = it is the variability in EPS due tochange in capital structure. It is caused due toleverage. If leverage is more, variability will be moreand thus financial risk will be more.
What is the optimal debt-equity ratio?
• Need to consider two kinds of risk:
– Business risk
– Financial risk
Theories of Capital Structure
1. Net Income Approach
2. Net Operating Income Approach
3. The Traditional Approach
4. Modigliani and Miller Approach
Firms use only two sources of funds – equity & debt.
No change in investment decisions of the firm, i.e. no
change in total assets.
100 % dividend payout ratio, i.e. no retained earnings.
Business risk of firm is not affected by the financing mix.
No corporate or personal taxation.
Investors expect future profitability of the firm.
Capital Structure Theories
-Assumptions
Where, E = market value of equityNI = earnings available to
- common stockholderske = Cost of equity
E = NI/ke
Where,ko= the firm’s overall cost of capital or
capitalization ratioEBIT = earnings before interest and tax
V = Value of the firm
ko = EBIT/V
Where,WACC= weighted average cost of
capital/ cost of capitalke= cost of equity
we = weight of equity(E/V)kd= cost of debt
wd = weight of debt(D/V)
WACC/ko=(ke*we)+(kd*wd)
ASSUMPTIONS:
1. COST OF DEBT < COST OF EQUITY
2. NO TAXES
3. RISK NOT INFLUENCED BY DEBT’S USAGE
Capital Structure Theories –1) Net Income Approach (NI)
Capital Structure Theories –1) Net Income Approach (NI)
Net Income approach proposes that there is a definite
relationship between capital structure and value of the
firm.
The capital structure of a firm influences its cost of
capital (WACC), and thus directly affects the value of the
firm.
As per NI approach, higher use of debt capital will result in
reduction of WACC. As a consequence, value of firm will be
increased.
Value of firm = Earnings
WACC
Earnings (EBIT) being constant and WACC is reduced, the
value of a firm will always increase.
Thus, as per NI approach, a firm will have maximum value
at a point where WACC is minimum, i.e. when the firm is
almost debt-financed.

Capital Structure Theories –1) Net Income Approach (NI)
A company expects a net income of Rs. 80,000. It has Rs.
2,00,000, 8% debentures. The equity capitalization rate of
the company is 10%.
Calculate:
(a) the value of the firm & overall capitalization rate.
(b) If the debenture debt is increased to Rs 3,00,000, what
shall be the value of the firm & overall capitalization
rate?

Capital Structure Theories –B) Net Operating Income (NOI)
Net Operating Income (NOI) approach is the exact
opposite of the Net Income (NI) approach.
As per NOI approach, value of a firm is not dependent
upon its capital structure.
Assumptions –
o WACC is always constant, and it depends on the business risk.
o Value of the firm is calculated using the overall cost of capital
i.e. the WACC only.
o The cost of debt (Kd) is constant.
o Corporate income taxes do not exist.
ASSUMPTIONS:
1. MARKET CAPITALISES VALUE OF FIRM AS A WHOLE
2. BUSINESS RISK REMAINS CONSTANT AT EVERY LEVEL OF DEBT EQUITY MIX
3. NO CORPORATE TAXES
Capital Structure Theories –B) Net Operating Income (NOI)
NOI propositions (i.e. school of thought) –
– The use of higher debt component (borrowing) in the capital
structure increases the risk of shareholders.
– Increase in shareholders’ risk causes the equity capitalization
rate to increase, i.e. higher cost of equity (Ke)
– A higher cost of equity (Ke) nullifies the advantages gained due
to cheaper cost of debt (Kd )
– In other words, the finance mix is irrelevant and does not affect
the value of the firm.

Hence, Cost of Equity (Ke) 10.71% 11.00% 11.33%
Capital Structure Theories –B) Net Operating Income (NOI)
A company expects a net operating income of
Rs.1,00,000. It has Rs 5,00,000 6% debentures. The
overall capitalization rate is 10%. Calculate the value of
the firm & cost of equity according to net operating
income approach. If the debenture debt is increased to
Rs 7,50,000. What will be the effect on the value of the
firm % the equity capitalization rate?

Capital Structure Theories –C) Traditional Approach
The NI approach and NOI approach hold extreme views on
the relationship between capital structure, cost of capital
and the value of a firm.
Traditional approach (‘intermediate approach’) is a
compromise between these two extreme approaches.
Traditional approach confirms the existence of an optimal
capital structure; where WACC is minimum and value is the
firm is maximum.
As per this approach, a best possible mix of debt and
equity will maximize the value of the firm.
The approach works in 3 stages –
1) Value of the firm increases with an increase in borrowings
(since Kd < Ke). As a result, the WACC reduces gradually. This
phenomenon is up to a certain point.
2) At the end of this phenomenon, reduction in WACC ceases
and it tends to stabilize. Further increase in borrowings will
not affect WACC and the value of firm will also stagnate.
3) Increase in debt beyond this point increases shareholders’ risk
(financial risk) and hence Ke increases. Kd also rises due to
higher debt, WACC increases & value of firm decreases.

Stage III
• Stage I Increasing Value : Ke either remains constant Ke does notincrease fast enough to offset the advantage of low-cost debt. Duringthis stage Kd remains constant. Ko decreases with increasingleverage and value of firm V also increases.
• Stage II Optimum Value : Beyond stage I any subsequent increase inleverage have a negligible effect on Ko and hence value of the firm.Increase in Ke due to the added financial risk just offsets theadvantage of low cost debt. Within this range, at a specific point Kowill be minimum and the value of the firm will be maximum.
• Stage III Declining Value : Beyond the acceptable level of leverage,the value of the firm decreases with leverage as Ko increases withleverage. Investors perceive a high degree of financial risk anddemand a higher equity capitalization rate which exceeds theadvantage of low-cost debt.
EBIT = Rs. 150,000, presently 100% equity finance with Ke = 16%. Introduction of debt to
the extent of Rs. 300,000 @ 10% interest rate or Rs. 500,000 @ 12%.

Capital Structure Theories –D) Modigliani – Miller Model (MM)
MM approach supports the NOI approach, i.e. the capital
structure (debt-equity mix) has no effect on value of a firm.
Further, the MM model adds a behavioural justification in
favour of the NOI approach (personal leverage)
Assumptions –
o Capital markets are perfect and investors are free to buy, sell, & switch
between securities. Securities are infinitely divisible.
o Investors can borrow without restrictions at par with the firms.
o Investors are rational & informed of risk-return of all securities
o No corporate income tax, and no transaction costs.
o 100 % dividend payout ratio, i.e. no profits retention
(IN THE ABSENCE OF TAXES)ASSUMPTIONS:
THERE ARE NO CORPORATE TAXES
THERE IS A PERFECT MARKET
INVESTORS ACT RATIONALLY
THE EXPECTED EARNINGS OF ALL THE FIRMS HAVE IDENTICAL RISK CHARACTERSTICS
ALL EARNINGS ARE DISTIBUTED TO THE SHAREHOLDERS

Implication:
• Overall cost of capital (ko) and the Value of the firm (V) remains constant.
• Independent of the capital structure.
• The total value can be obtained by capitalizing the operating earnings stream
• Size of the corporate pie = PV of cash flows
• V=EBIT/ko
Proposition I
Proposition II
• The cost of capital (ke) equals thecapitalization rate of a pure equity stream anda premium for financial risk.
• Ke=ko+Risk premium• The premium for financial risk is equal to the
difference between the pure equitycapitalization rate and kd times the debt-equity ratio.
• Ke=ko+(ko-kd)(D/E)
Limitations of MM approach
• Investors cannot borrow on the same terms and conditions of a firm
• Perfect Capital Markets
• Existence of transaction cost
• Floatation costs
• Asymmetric information
• Existence of corporate tax
• Uncertainty
