Sinha gave credit for this change to growing activism of institutional investors, stronger regulations and an improved surveillance mechanism at Sebi, while asking independent directors to act like "an extended arm of the regulator" when companies discuss business matters in their board meetings.
The Sebi chief also asserted that the onus needs to be put more on the promoters or the top executives, rather than the companies as a whole, when it comes to penalties.
He also rejected the criticism that regulators were becoming activists and praised the institutional investors for adopting an effective activism to put shareholder proposals for proper discussions.
"There is a feeling that regulators are becoming activists. In fact one particular corporate leader made a remark that Sebi is becoming a dragon and may be we will have to move to other parts of the world to do business," he said.

"Many people even didn't go to attend board meetings and it was granted that it (their renominations) was going to happen. In fact the general meetings of corporates of India were mainly a 'chai and samosa' party," he added.
"There is an alliance now of institutional investors and activists. Previously this alliance did not exist and because of that even if there were some murmurs... It was not proven to be effective. Now, in countries after countries this alliance is proving its worth and they are proving they can be effective," Sinha said.
"More and more resources are placed before the regulators. Between 2006 and 2013, the US market regulator SEC has increased its expenditure by 62 per cent and employee strength by 22 per cent. For the FCA in the UK, the numbers are 48 per cent and 15 per cent. Similarly it is happening in many other countries," Sinha said.
He added: "In India, for example, in 2006 we had only 440 employees and today we have 760 employees... We are now recruiting chartered accountants from the campuses, we are recruiting statisticians, system analysts and IT professionals.
