Capital Structure in Financial Management

Topic Covered in this page

Capital structure in financial management:

There are several important decisions to be taken under financial management. One of the important decisions is regarding the proportion of use of different kinds/sources of funds to be used. It is thus the financing pattern which should be chosen so that the returns are higher. Sources of funds are classified as:

  1. On the basis of duration/period:
  • Long term sources
  • Medium term
  • Short term




  1. On the basis of ownership:
  • Owner’s funds
  • Borrowed funds
  1. On the basis of source from which they are generated:
  • Internal sources
  • External sources

Capital structure mainly focuses on the combination of sources on the basis of ownership. Owner’s funds include personal savings, retained earnings, reserves and surpluses, equity share capital and preference share capital. Borrowed funds include the debentures, loans from financial institutions, loans from banks, public deposits; lease financing etc. Capital structure is thus the mixture of- owners fund and borrowed funds which are called equity and debt.

Capital structure can be calculated as the ratio of debt to equity or proportion of debt out of total capital (debt + equity).

Capital structure= debt/equity
OR
Capital structure= debt/debt + equity

Capital structure in financial management

The mixture of the two is important because each one has its own benefits and limitations. They differ on the basis of cost involved and risk associated.

Debt is considered the cheapest source but a risky one. It is considered cheap because lenders get an assured return and repayment of capital becomes necessary, thus it involves lower rate of return. The interest paid on the debt is a deductible expense. It is considered risky because payment to the lenders is obligatory. Default of payment can lead to liquidation of the business.  Thus, higher the debt, higher will be the financial risk of the firm. Financial risk is the risk where firm is not in a position to pay back the debtors and cannot fulfil the obligations.




Equity on the other hand is less risky but involves more cost as compared to the debt. It is less risky because it does not involve any financial risk and it is not an obligation to pay the shareholders. When there is liquidation of the firm, it is last on the priority list for paying back. Moreover, dividends paid to the shareholders are out of after tax profits.

Capital structure is thus a mixture which should be properly analysed as it affects the profitability, liquidity and financial risk of the business. It should be such that it increases the price of the shares and the overall wealth of the shareholders as it is the main aim of financial management.

Financial leverage

Proportion of debt in the overall capital of the business is called the financial leverage. When the financial leverage increases, the overall cost of the funds decline but it comes with the higher risk. Impact of debt/financial leverage can be seen through a technique called EBIT-EPS analysis, earnings before interest and tax – earning per share.

Case I:

Favourable Financial leverage

In these three situations, earning before interest and tax is Rs. 6, 00,000.

The interest rate charged is 10% which will be equal to zero in situation 1 because of no debt involved, Rs. 2 lakhs in situation 2 because of 20 lakhs debt and Rs 3 lakhs in situation 3 because of 30 lakhs debt involved.

So the earnings before tax will be calculated (interest rate subtracted from EBIT)

Then tax will be deducted on the EBT which will give us earning after tax (EAT).

Total number of shares at the rate of Rs.10 each will be:

Situation 1 – Rs 50 lakhs divided by Rs. 10 = Rs. 5 lakhs

Situation 2 – Rs. 30 lakhs divided by Rs 10 = Rs. 3 lakhs

Situation 3 – Rs. 20 lakhs divided by Rs 10= Rs. 2 lakhs

This will give us earning per share (EPS) which is equal to EAT divided by number of shares.

As we can see that the earning per share is increasing with the increase of debt in the capital structure, this is because of the return on investment is higher than the interest paid. Return on investment is 12% and interest rate is 10%. {Return on investment (ROI) = EBIT/total investment * 100}. This case is called the favourable financial leverage. Here, the company employs cheaper debt so that the higher EPS can be obtained and it is called trading on equity.




Case II:

There can be a case where the return of investment is lower than the interest rate, and then in that case the earning per share will decline with the increase of debt in capital structure. That situation will be the unfavourable financial leverage and trading on equity will not be advisable for the company.

Here each detail is same except the EBIT, that is, Rs.3 lakhs.

Unfavourable Financial leverage

Here we can clearly see that with the increase in debt, the EPS is declining. It is because of the ROI (6%) being lower than the interest rate (10%).

Thus, these two cases show that the return on investment should be higher than the interest we are paying and optimum balance of debt and equity should be selected so that risk and cost are kept as low as possible and the main aim of maximising the shareholders wealth is reached.

Factors affecting the choice of capital structure

  1. Cash flow position: cash flow position plays a very important role in choosing the ratio of debt and equity because cash is very necessary for a business. It requires cash for normal course of business i.e. day to day activities, for payment of interest on the debt taken or repayment of principles, and also for investment activities such as expansion of business or getting new machinery.
  2. Interest coverage ratio (ICR): Although, this is not an adequate measure but should be taken into account. Interest coverage ratio is the ratio between the earning before interest and taxes (EBIT) and the interest. This shows how much earnings we have in comparison to the interest we need to pay. Higher the ratio, lower will be the risk of default on interest payment. This is not considered an adequate factor because it does not take the repayment of principle into account.
  3. Debt service coverage ratio (DSCR): debt service coverage ratio is the ratio which shows how much cash is available to pay the debts of the firm including the interest, principle and lease payments. This ratio is broader than the interest coverage ratio and includes the areas which ICR lacks.
  4. Return on investment (ROI): return on investment is a very important factor because it helps in finding out how much debt in the capital structure will be considered the favourable financial leverage and will help in maximising the shareholder’s wealth. When the return on investment is higher than the interest rate then the condition is considered to have a favourable financial leverage and the debt can be taken more and it would help in trading on equity.
  5. Cost of debt: each source of fund comes with some cost. Debt is however considered the cheapest cost but still it includes the payment of interest. When a firm gets the debt at a lower rate, then it can take up higher debt.
  6. Cost of equity: due to the risk the shareholders assume, they expect a higher rate of return. When the debt in capital structure increases, the financial risk increases and this risk is taken by the shareholders and thus they expect a higher dividend/higher rate of return. That is why, only certain amount of debt can be included in capital structure so that the cost of equity does rise too much.
  7. Risk: there are two types of risks which are to be considered- financial risk and business risk. Financial risks the risk where the firm is unable to meet its financial obligations such as interest, repayment of principle and dividend on preference shares. Business risk is the operating risk which means the firm has higher operating cost. When business risk is lower the firm is in a position to take up more debt in its capital structure.
  8. Flexibility: A firm should choose the right proportion of the debt and equity so that it is flexible enough for the unforeseen circumstances.
  9. Control: equity comes with dilution of control. Shareholders are considered owners because they can take part in the management of the firm and thus dilution of the control takes place. If the firm does not want that the control gets more diluted then it should keep the funds from equity to a limited extent.
  10. Regulatory framework: each source of finance has its own regulations for raising the fund. For example: issuing the shares should be done under the SEBI guidelines, loans or debentures also have certain rules and norms. When these procedures are easy then the source becomes attractive.
  11. Stock market conditions: there are two situations, bullish stock market period where the stocks are sold easily even at a higher price and bearish stock market period where it becomes difficult for the firm to issue the shares. These conditions play an important role in choice of source of funds.
  12. Industry norms: a company must consider other company’s capital structure of the same industry. This will help a firm in deciding what kind of combination to choose. Although it should be carefully analysed first and should not be followed blindly because each company is different and has its own cash flow position, operating/business risk etc.

Capital structure is the financing pattern which the company chooses from the funds based on ownership- owner’s fund and borrowed funds. These funds are different in their risk and cost. An ideal ratio between debt and equity is considered to be 2:1, but a company should properly analyse the position of the firm and other factors before taking any decision because it can have affect on its profitability, liquidity and financial risk. Other factors such as cash flow position, interest coverage ratio, debt service coverage ratio, flexibility, control, regulatory framework, stock market conditions are also important and should be considered before taking the decision so that there are no regrets later on.
