specialists, such as health and safety officers to check compliance with health and
safety regulations, and compliance officers to check on compliance with other major
regulations. If the company uses specialist managers to check on compliance, there
is no need for an internal audit function to do this work.
In some companies, an internal audit function might be used to assist with the
identification and assessment of business risks and risks in the company’s business
environment. Other companies might appoint specialist risk managers. The need for
an internal audit function to assist with risk management will depend partly on
whether it has specialist risk managers. If it does not have specialist risk managers,
the need for an internal audit function to assist with risk management will depend
on a judgement about whether internal auditors could make an additional and
effective contribution to the current risk management system.
Internal auditors might also carry out investigations into the economy, efficiency
and effectiveness of operational systems (value for money audits). The audit
committee should assess whether the company would benefit sufficiently from VFM
audits to justify an internal audit function to perform this work.
Internal audit has traditionally been associated with investigations into financial
controls and the reliability of accounting systems and financial reporting. Where an
internal audit function does this work, the external auditors might be able to rely on
work done by internal audit. This would reduce the amount of work – and cost – for
the external audit. The audit committee should make an assessment of the strength
of current financial controls, to decide whether an internal audit function would
improve the quality of the control system (and if so whether the cost would be
justified).
The need for an internal audit function depends on the scale and extent of
weaknesses in the internal control system. If the audit committee considers that
there seem to be extensive weaknesses in internal control, the introduction of an
internal audit function should help to improve the control system and provide a
benefit to the company. If the audit committee considers that current controls are
sufficient, it will reach a view that an internal audit function is not (yet) required.
However, it must be able to explain to the board the reasons for the
recommendation that it makes.
27 Audit committee
(a) An audit committee consists entirely of independent non-executive directors,
and it meets on only a few occasions each year, possibly about four times a
year. An audit committee has no executive responsibilities. So it cannot take
away executive responsibilities from the finance director, a full-time executive
of the company.
However, an audit committee does have some responsibilities that might once
have belonged entirely to the finance director (or the CEO).
The audit committee provides an extra line of reporting for the internal
auditors and external auditors. As well as reporting to the finance
director, the auditors must also report to the audit committee.
