It is because the Shares underlying Depository Receipts has decreased from 1,41,78,690 (Dec 2017) to 1,36,23,540 (Mar 2018) which correspondingly increased the shares available for public from 11,89,06,376 (Dec 2017) to 11,94,09,507 (March 2018) by the same quantity. As a causality the promoter share holding percentage has taken a dip marginally although the shares they held cumulatively has increased slightly on a quarter on quarter basis.
On a side note these deposity receipt shares are held by DBS (Nominees) Private Limited as per below link:
Since I don’t have clue of the Accountancy and Jargon associated with this:
What are Depository repository shares and does this mean Development Bank of Singapore (https://en.wikipedia.org/wiki/DBS_Bank) holds these shares on behalf of Foreign Portfolio investors from Singapore?
Is this a good sign that they are offloading such huge quantity of shares quarter on quarter? To add to this the number of shares held under DR are getting reduced significantly over the years 3,74,33,450 shares (March 2016) to 1,36,23,540 shares (March 2018).
One more thing I noticed is that Individual investors with share capital upto Rs. 2 Lacs (Retail Investors) share holding is 28.47 percentage as on March 2018 and this has increased significantly over the years from 5,33,12,495 shares (March 2016) to 6,85,23,028 shares (March 2018). Is this a good sign?
