Last week’s order says, “Sebi issued repetitive reminders vide emails/letters dated October 24, 2016, November 09, 2016, December 19, 2016 and May 18, 2017, as a result, NSE submitted a report dated November 22, 2017 of its NRC vide its email dated November 29, 2017 and subsequently, vide its letter dated September 14, 2018.”
The DRHP also talks about Ramkrishna’s resignation and lists the prospect of not finding a suitable replacement as a risk factor.
NSE’s first attempt to go public didn’t materialise as the exchange got embroiled in a legal tangle with Sebi over the colocation issue. Since then, NSE's board and management has undergone a total revamp.
