Which of the following is NOT a way to redeem the debentures?

Conversion into shares only NOT in new debentures

The correct answer is Option (4) - Conversion into shares only NOT in new debentures.

The four ways of redemption of debentures are:
1) Payment in lump sum: This involves repaying the entire principal amount of the debentures in a single payment.

2) Payment in installments: Debentures are redeemed by making periodic payments, often in multiple installments, according to a predetermined schedule.

3) Purchase in the open market: The company can buy back its own debentures from the open market if they are available for purchase. When a company purchases its own debentures in the open market for the purpose of immediate cancellation, the purchase and cancellation of such debentures are termed as redemption by purchase in the open market.

4) By conversion into shares or new debentures: Debenture holders may have the option to convert their debentures into either equity shares or new debentures issued by the company.
