Filings before Sep 2022 are on an older form, which did not split institutions into foreign and Indian and grouped some holders differently, so those columns show only the lines both forms state alike. A dash is a line the filing did not state. “None” is a filing that names no promoter holding shares. “Under 0.01%” is a holding of shares too small to show at two decimals.
