If an individual has 10 shares of a company in one demat account and 5 shares in another, and the company has announced a rights issue in the ratio of 1:15, would they be eligible to exercise the rights?

RTA determined the eligibility on a folio-wise basis and even if both the demat account is linked with the same PAN number then shares will be held separately in RTA folios as records. Therefore in this case an individual has 10 shares in one demat account and 5 shares in another, they would not receive the rights entitlement.
