Debentures — Advantages, Disadvantages, and Comparison with Preference Shares

## Debentures as a Source of Long-Term Finance

### What is a Debenture?

A debenture is a debt instrument issued by a company to raise long-term funds from the public. Debenture holders are creditors — not owners — of the company. They lend money and receive a fixed rate of interest regardless of the company's profits.

### Advantages of Debenture Financing

#AdvantageWhy It Matters
1No Dilution of ControlDebenture holders have no voting rights → promoters retain full management control
2Tax Shield on InterestInterest paid is tax-deductible → reduces the effective (after-tax) cost of debt
3Inflation AdvantageFixed interest means the real cost of debt falls during inflationary periods

---

### Disadvantages of Debenture Financing

#DisadvantageWhy It Matters
1Fixed Financial CommitmentInterest and principal must be paid compulsorily, even in loss years
2Restrictive CovenantsTrust deed may impose conditions limiting the company's financial freedom
3Increased Financial RiskHigh debt levels increase the probability of default
4Large Repayment at MaturityBullet repayment of principal can create severe cash flow strain

### Preference Shares vs Debentures

BasisPreference SharesDebentures
NatureSpecial kind of share capital (part-ownership)Type of loan raised from the public (creditor relationship)
PaymentFixed dividend + priority in capital repayment on winding upFixed rate of interest — mandatory irrespective of profits
ClassificationHybrid — combines features of equity and debtPure debt instrument with fixed maturity

> Memory anchor: Preference shareholders are part-owners (hybrid instrument). Debenture holders are pure lenders (creditors).

Worked example

### Example 1

A company has ₹10 crore debentures at 10% interest. Its profit before interest and tax (PBIT) is ₹3 crore. The company must still pay ₹1 crore interest even though it may have insufficient distributable profits — illustrating the 'fixed financial commitment' disadvantage.

### Example 2

Company X is financed 60% by debentures at 12% and pays 30% tax. Effective cost of debt = 12% × (1 − 0.30) = 8.4%. A preference share at 12% dividend costs the full 12% since dividends are not tax-deductible — illustrating the tax shield advantage of debentures over preference shares.

### Example 3

Inflation rises from 3% to 9%. A company paying 10% fixed interest on debentures now bears a real interest cost of approximately 1% (10% − 9%) instead of 7% (10% − 3%) — the real cost has dramatically reduced, illustrating the inflation advantage.

⚠️ Common exam mistakes

  • Confusing debenture holders as shareholders — debenture holders are creditors with no voting rights, not owners.
  • Saying preference dividend is tax-deductible like debenture interest — it is NOT; only interest payments are tax-deductible.
  • Treating preference shares as pure equity — they are a hybrid instrument with both debt and equity characteristics.
  • Forgetting that the inflation advantage applies because the interest rate is FIXED — floating rate debentures do not provide the same inflation protection.
