Answer: Irredeemable bonds or perpetual bonds

 

Bonds which will never mature are known as irredeemable or perpetual bonds. Indian Companies Act restricts the issue of such bonds and therefore, these are very rarely issued by corporates these days. In case of these bonds, the terminal value or maturity value does not exist because they are not redeemable. The face value is known, and the interest received on such bonds is constant and received at regular intervals and hence, the interest receipt resembles perpetuity. The present value is calculated as:


Where Vo is the present value; ‘I’ is the annual interest payable on the bond and ‘’ is the required rate of interest.

 

If a company offers to pay Rs. 70 as interest on a bond of Rs. 1000 per value and the current yield is 8%, the value of the bond is 70/0.08 which is equal to Rs. 875.
