The National Stock Exchange's issue records contain the anchor allocation reports and issue disclosures for these companies. BSE has also published anchor allocation notices for several of the issues.

The number of shares becoming eligible for trading and the proportion of total equity represented by these shares will depend on the respective anchor allocation and post-issue shareholding disclosures.
