According to the report, of all the companies with equity shares listed on the NSE main board, the Big 6 Indian audit firms secured 637 assignments out of 1,961. This accounted for approximately 32.48% of the total, up slightly from 32.14% the previous fiscal year. Auditor details were missing for 47 organisations. A key standout has been the strong performance of Grant Thornton and MSKA affiliates who have established themselves as strong alternatives to the Big Four firms in audit business.
