Factors affecting the Choice of Capital Structure

• Deciding capital structure means deciding the proportion of different types of funds (like debt) used by a firm.
• This depends on several factors because debt needs regular servicing (interest and repayment of principal) and the firm must have enough cash for these payments.

• Cash flow position: projected cash flows must be enough to pay for operations, fixed assets, interest and repayment of principal with some buffer.
• Interest Coverage Ratio: higher ICR (EBIT ÷ Interest) means lower risk of failing to pay interest; but cash balance and repayment obligations also matter.
• Debt Service Coverage Ratio: higher DSCR (cash profit ÷ total cash needed for debt and preference share capital) means better ability to meet cash commitments and more scope to use debt.
• Return on Investment: higher RoI (like 13.33%) makes trading on equity profitable and allows more debt; lower RoI (like 6.67%) than cost of debt reduces EPS and limits debt use.
• Cost of debt and tax rate: borrowing at a lower rate and higher tax (10% debt, 30% tax giving 7% after‑tax cost) make debt cheaper and more attractive than equity.
• Cost of equity and risk: more debt raises financial risk for equity holders, increases required return, and can reduce share price; so debt should be used only up to a safe level.
• Floatation costs: public issue of shares/debentures is costly, while loans may be cheaper, affecting the choice between debt and equity.
• Risk consideration: total risk depends on business risk (fixed operating costs) and financial risk (fixed financial charges); lower business risk allows higher use of debt.
• Flexibility: using full debt capacity reduces flexibility; firms should keep some borrowing power for unforeseen needs.
• Control: debt normally does not dilute control, but issuing equity can reduce management holding and increase takeover risk, influencing the choice between debt and equity.
• Regulatory framework: SEBI guidelines for public issues and norms for bank/financial institution funds affect how easily each source of finance can be used.
• Stock market conditions: in bullish markets equity is preferred and easily sold at higher price; in bearish markets firms may opt for debt.
• Capital structure of other companies: industry debt‑equity norms give useful guidelines, but firms with higher business risk should not follow them blindly and should use lower debt.

• Capital structure choice depends on cash flows and ability to meet fixed payments.
• ICR and DSCR show how safely a firm can service interest and total debt.
• RoI compared with cost of debt decides whether trading on equity raises or lowers EPS.
• Tax rate, cost of debt, and cost of equity change the attractiveness of debt versus equity.
• Business risk, financial risk, flexibility, and control limit how much debt can be used.
• Laws, SEBI rules, stock market conditions, and industry norms also influence capital structure decisions.
