Mumbai, October 22: From now onwards, statutory auditors will have to comply with stricter norms when it comes to their resignation. Market regulator, Securities and Exchange Board of India (Sebi) has recently issued a circular stating that auditors resigning from listed companies are required to give detailed reasons to stock exchanges at earliest. Sebi, in its consultative paper in the month of July, highlighted that resignation of an auditor before completion of audit of financial results for the year seriously hampers investor confidence.
