Types of assurance engagements include: performance measurement; internal
controls, risks, systems reliability, e-commerce, social matters, environmental issues
and corporate governance and compliance. Following an assurance engagement
process and producing a report at the end can lead to increased credibility. The
assurance report may involve a report that expresses a conclusion on the assertion
by the responsible party on the subject matter.
Comparison to an audit – less work and a lower level of assurance?
An assurance engagement may involve the same challenges as for an audit in that
concerns may arise which could impact on the conclusions drawn. For example,
identified criteria might not be met, an inappropriate assertion may have been
made, evidence may not be sufficient. In this case, a reservation of conclusion
(disagreement) or a denial of conclusion (limitation on scope) may be expressed and
the report must include all significant facts and reasons supporting the conclusions.
As with any engagement, the firm must give consideration to the significance and
materiality of its findings.
A traditional audit service involves conducting an audit and providing a report as
to whether the financial statements provide a true and fair view and that accounting
standards have been complied with. This is a long established practice, with
published professional standards and outputs that are generally seen as credible
and reliable by clients and users of reports provided. An audit may provide a high
(but not absolute) level of assurance and result in a report providing a positive
assurance on assertions.
Different levels of assurance can be provided for other assurance engagements,
ranging from a high level of assurance to a very low level. Usually, a non-audit
assurance engagement provides a high or moderate level as follows:
A high level of assurance refers to the firm having obtained sufficient,
appropriate evidence to conclude that the subject matter conforms to identified
suitable criteria in all material respects.
A moderate level of assurance is provided when sufficient, appropriate evidence
is obtained to be satisfied that the subject matter is plausible in the
circumstances.
An absolute level of assurance cannot be provided because of the nature of any
assurance engagement. The subject matter is not necessarily clear cut, the nature,
timing and extent of procedures may be limited, there may be difficulties in
establishing sufficient evidence and the types of approach and testing procedures
used vary from the standard audit approach.
A high level of assurance can only be given if the subject matter is the responsibility
of another party, is identifiable and can be subject to evidence procedures and there
are suitable criteria against which a conclusion can be expressed.
Guidance on and difficulties of assurance engagements – less risk?
There are fewer published standards on assurance engagements although
International Standard on Assurance Engagements 3000 establishes the basic
