Management Letter vs Representation Letter: Purpose, Timing and Content
Quick answer: A management letter is issued by auditors to communicate control deficiencies to those charged with governance. A representation letter is signed by management and confirms key assertions to the auditor. They serve different purposes and are issued at different times.
Management Letter
A management letter (also called an audit observation letter or letter of weakness) is issued by the auditor to the client's board of directors or audit committee. It communicates:
- Control deficiencies identified during the audit
- Suggested improvements to internal controls
- Matters arising from the audit that merit attention
- Previously reported issues that remain unresolved
Management letters are not required by auditing standards for all engagements, but are issued as a matter of best practice by most audit firms. They supplement the formal audit report.
Representation Letter
A representation letter (or management representation letter) is a written confirmation signed by the client's management. It confirms key assertions that management is responsible for. Under ISA 580 (or AS 2301 under US GAAS), the auditor requests this letter near the completion of the audit.
Typical contents include:
- Financial statements are the responsibility of management
- All material transactions have been recorded
- Completeness of information provided to the auditor
- No undisclosed liabilities or contingent liabilities
- No fraud or non-compliance with laws affecting the financial statements
- Correct classification of items as debt vs equity
