The National Stock Exchange of India Limited applies Long Term Additional Surveillance Measure to specific securities. These securities satisfy the criteria for inclusion in the surveillance framework. The exchange mandates a 100 percent margin rate for all open and new positions in these securities.

This surveillance measure works with other existing exchange measures. The inclusion of a security in this list does not represent an adverse action against the company.

- Shift securities qualifying under criteria VII from Rolling Settlement segment to Trade-for-Trade segment.
