controls. As a consequence, other weaknesses may exist that are not mentioned in

4.2 The management letter
Although now a requirement of both ISA 315 and ISA 265, the management letter
or letter of weakness has long been seen as an extra service provided to the client
by the external auditor. If management address the points in the letter, the controls
in place will be improved. This may enable future audits to focus on the more
efficient systems-based approach. This in turn may reduce the cost of the audit to
the client.
The report is prepared and sent after the results of the tests of control are known –
usually after the interim audit.
The report may later be updated after the final audit, if further weaknesses have
been found, or if weaknesses that were reported to previously have not yet been
dealt with.
In line with ISA 265’s requirement to give a description of the deficiencies and an
explanation of their potential effects, the report will usually identify the following
information for each weakness reported.
The nature of the weakness in the present system, in terms of both design and
operation. (In other words, is there a control weakness ‘on paper’? If there is no
control weakness ‘on paper’, are the controls applied effectively in practice?)
The implication of this weakness in controls.
Recommendations for improvement.
The auditor should ask management to provide a response and action plan for each
weakness identified in the report. He should also mention that the contents of the
report will be followed up in future audits.
An earlier chapter looked at the identification of specific control “risks” and asked
for suggestion of controls to mitigate these risks. This topic could also be tested in
the exam in the context of the preparation of a management letter.
Example
You are the auditor of AdviceCo. During your audit of the purchases cycle you have
identified the following weaknesses:
1. Payables ledger clerks amend standing data held on the standing data
masterfile when they are instructed to do so by the buying manager.
2. The financial director signs cheques made out to suppliers without sight of any
supporting documentation.
