What’s a rights issue?
A rights issue is a way by which a listed company can raise additional capital. However, instead of going to the public, the company gives its existing shareholders the right to subscribe to newly issued shares in proportion to their existing holdings.
For example, 1:4 rights issue means an existing investor can buy one extra share for every four shares already held by him/her. Usually the price at which the new shares are issued by way of rights issue is less than the prevailing market.
