Limitations of Audit

dAn auditor cannot obtain an absolute assurance that material misstatements in the financial statements will be detected. There is unavoidable risk involved that some material financial misstatements may not be detected even auditing has been completed using proper planning and as per the prescribed auditing standards. The Auditor can only obtain a reasonable assurance that the material misstatements in the financial statements will be detected.

The risk of not detecting a fraud is much higher that the risk of not detecting a material misstatement resulting from an error as frauds are much deeper rooted and well covered. Normal auditing procedures which are effective in discovering error are usually not effective enough for detecting frauds.
Management fraud is much more difficult to detect and the auditor may simply not detect it at all. The opinions of the Auditors are base on what is present before him and subsequent discovery of fraud or a material misstatement in the financial statements does not indicate any failure on part of the auditor to obtain reasonable assurance or absence of professional competence or failure to comply with auditing standards.

When planning and conduction audit, the auditor must make inquiries of management, obtain a written assurance that the management has prepared the financial statements with due care considering the fact that the internal control and accounting and procedure put in place by the management takes care of such risks. The management’s assessment of the risk that there may be material misstatements in the financial statements as a result of fraud. The Auditor must make enquiries if the management is aware of any known fraud that had affected the internal control system that the entity is investigating into
Audit risk is the risk that the auditor gives an inappropriate audit opinion when the financial statements are materially mismatched. Such misstatements can result from either fraud or error. There are three types of audit risks – inherent risk, control risk and detection risk.
