2.3 Independence of the external auditors
This text does not explore in detail the role of the external auditors. However, a
critical aspect of good corporate governance is the need for the board to ensure that
the external auditors carry out their audit work properly, so that the board of
directors is able to rely on the conclusions and recommendations they provide at the
end of the audit.
One of the requirements for the auditors is that they should perform their audit
work with independence. In this sense, independence means freedom from the
influence of the company’s executive management.
There are at least two ways in which the independence of the auditors might be at
risk.
Familiarity of the audit firm or audit partner with the company. When the
same audit partner is responsible for the audit of a particular client company
every year for a long period of time, he or she is likely to become very familiar
with the company and its management. As this familiarity grows, the audit
partner will probably become more willing to accept assurances from
management and rely on the accuracy of the information they provide. This
obviously can be a very serious problem when the assurances given by
management are false and the information is incorrect or incomplete.
Non-audit work and a reliance of the audit firm on the company for a large
amount of fee income. An audit firm receives an audit fee each year. In addition,
it is common for the audit firm to obtain a substantial amount of fee income
from non-audit work, such as providing tax advice and advice on information
systems, and carrying out investigations for the company. If an audit firm
obtains a large amount of its income from one corporate client, it will probably
be reluctant to disagree with the company’s management on issues relating to
the preparation of the financial statements (such as the size of estimates and the
application of accounting policies).
The audit firm Arthur Andersen collapsed in 2002 as a result of the Enron scandal.
Andersens were the auditors of Enron, and it was found that the firm, in particular
its office in Houston Texas, was not independent of the company. The publicity
given to Andersens led to a general loss of confidence in the audit firm, which was
dissolved.
The problem of familiarity of the auditors with an audit client can be reduced by
either:
rotation of the audit firm, so that the same audit firm does not carry out the
audit of any company for more than a maximum number of years, or
rotation of the audit partner, so that the same audit partner is not responsible
for the audit of any company for more than a maximum number of years.
Rotation of audit partners has become a regulatory requirement in some countries
(including the UK), as a means of dealing with this problem.
