The third source is Securities Exchange
Commission web site (www.sec.or.th) which
provides us the auditors who are granted to sign in
financial statement of listed companies. In this
source, there also provides us the audit firm where
granted auditors are members. Due to the financial
fraud of Enron and the merger between 2 big 6,
there are now only big 4 auditors that survive
beyond 2005 (PricewaterhouseCoopers, Ernst &
Young, Deloitte Touche Tohmatsu, and KPMG).
