Listing out instances of corporate misdoings in different parts of the world, he said "our own jurisdiction has also been marred by various corporate scandals".
"These range from suppression of information to selective sharing of information to falsification of accounts to other aspects of misgovernance such as poor board evaluation and inequitable executive compensation," Tyagi said without taking names.
Speaking at a corporate governance summit here, the Sebi chief said the scandals of Enron, Parmalat and WorldCom shook investor confidence and spurred governance reforms in the past decade.
Observing that there has been a spurt in cases that has brought into question the efficacy of corporate governance norms, Tyagi said cases of undue suppression of information from the shareholders "like the recent Volkswagen emission case, or cases of deliberately falsifying data from customers like the very recent Kobe Steel scandal in Japan have shaken investor confidence".

According to him, there have also been cases of differential treatment to different classes of shareholders like Snapchat and Facebook and cases of over-inflating profits by companies like Toshiba.
Closer home, Tyagi said, if one takes a deeper dive into the happenings in the corporate world, it becomes immediately apparent that "our own jurisdiction has also been marred by various corporate scandals".
Without citing any particular instance, the Sebi chief said that he is persuaded to "see a distinct blur in letter and spirit" with regard to the corporate governance practices followed by many companies.
Further, he said companies do follow rules and regulations, and if their governance practices are put to test, they will likely stand scrutiny of the law.
He was speaking at the summit organised by corporate governance advisory firm Excellence Enablers founded by former Sebi chairman M Damodaran.
