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. Pledged is the share of the promoters' own shares given to lenders as security. A dash is a line the filing did not state. “Under 0.01%” is a holding of shares too small to show at two decimals.

A filing names every holder above one per cent, in the company's own words: an insurer's holding can carry one of its funds' names. Mutual funds are left out here: each fund's holding is on the Mutual funds tab, from its own portfolio. A dash is a filing that did not name the holder, which includes holding under one per cent.
