From company’s rights issue letter of offer.
The Eligible Equity Shareholders holding less than 26 (Twenty-six) Equity Shares as on Record Date shall have ‘zero’ entitlement in the Issue. Such Eligible Equity Shareholders are entitled to apply for additional Equity Shares and will be given preference in the allotment of one additional Equity Share if, such Eligible Equity Shareholders apply for the additional Equity Shares. However, they cannot renounce the same in favour of third parties and the application forms shall be non-negotiable.
So if you have less than 26 shares, you won’t get any REs. However, if you apply for additional shares in the rights issue, you will get a preferential allotment for 1 share.
