Sir it is rightly said that the auditor is a watchdog not a bloodhound. His limitations are just to warn you , like a watch dog when a stranger enter house of master he just barks & get it to the notice of his master than some unknown has entered the house. The dod do not start biting the stranger. It is the duty of the owner to take action.
Watch dog means he is there to guard the shareholders equity , check on the account and report on the findings not preventing fraud or playing detective , if a company write the true about it position , the auditor needs not do anythings just report on it
