Non-convertible debentures fall under the debt category. They cannot be converted into equity or stocks. NCDs have a fixed maturity date and the interest can be paid along with the principal amount either monthly, quarterly, or annually depending on the fixed tenure specified. They benefit investors with their supreme returns, liquidity, low risk and tax benefits when compared to that of convertible debentures. The customers can invest when the company announces NCDs or purchase after it trades on the secondary market.
