Debenture Financing – Advantages, Disadvantages & Comparison with Preference Shares

## Debenture Financing

### Why companies use debentures

Debentures are debt instruments that allow companies to raise long-term capital without diluting ownership. They come with fixed interest obligations, which can be both an advantage and a risk.

### Advantages

AdvantageExplanation
No Dilution of ControlDebenture holders have no voting rights
Tax ShieldInterest is a tax-deductible expense → lowers effective cost
Inflation AdvantageFixed interest means the real cost decreases during inflationary periods

### Disadvantages

DisadvantageExplanation
Fixed Financial CommitmentInterest and principal must be paid, even in losses
Restrictive CovenantsLenders may impose conditions limiting management freedom
Increased Financial RiskHigh debt-to-equity ratio raises the risk of default
Large Repayment at MaturityBullet repayment can strain cash flows

### Preference Shares vs. Debentures – Key Differences

BasisPreference SharesDebentures
OwnershipSpecial kind of share capitalType of loan from the public
PaymentPriority dividend + return of capital on winding upFixed percentage interest
NatureHybrid – part equity, part debtPure debt with fixed maturity

Worked example

### Example 1

A company earns ₹10 lakh pre-tax profit. It pays ₹2 lakh as debenture interest. Tax rate = 30%. Tax is computed on ₹8 lakh (not ₹10 lakh), saving ₹60,000 in tax. This is the tax shield benefit of debentures.

### Example 2

During 10% inflation, a debenture carries 8% fixed interest. The real cost of borrowing = 8% − 10% = −2%, meaning the company effectively benefits from inflation.

⚠️ Common exam mistakes

  • Confusing 'no dilution' as meaning debentures have zero risk — they carry fixed payment obligations regardless of profit.
  • Stating that preference shareholders get dividend before debenture interest — it is the reverse; debenture interest is paid first as it is a debt obligation.
  • Thinking debentures and preference shares are both equity — preference shares are part of share capital; debentures are liabilities.
