正确答案：

You will be aware of the importance of accurate resource valuation to Worldwide Minerals (WM). Unfortunately, I have to
inform. you that the reserve of mallerite, one of our key minerals in a new area of exploration, was found to have been
overestimated after the purchase of a mine. It has been suggested that this information may have an effect on shareholder
value and so I thought it appropriate to write to inform. you of how the board intends to respond to the situation.
In particular, I would like to address two issues. It has been suggested that the overestimation arose because of issues with
the internal control systems at WM. I would firstly like to reassure you of the importance that your board places on sound
internal control systems and then I would like to highlight improvements to internal controls that we shall be implementing
to ensure that the problem should not recur.
(i) Importance of internal control
Internal control systems are essential in all public companies and Worldwide Minerals (WM) is no exception. If anything,
WM’s strategic position makes internal control even more important, operating as it does in many international situations
and dealing with minerals that must be guaranteed in terms of volume, grade and quality. Accordingly, your board
recognises that internal control underpins investor confidence. Investors have traditionally trusted WM’s management
because they have assumed it capable of managing its internal operations. This has, specifically, meant becoming aware
of and controlling known risks. Risks would not be known about and managed without adequate internal control
systems. Internal control, furthermore, helps to manage quality throughout the organisation and it provides
management with information on internal operations and compliance. These features are important in ensuring quality
at all stages in the WM value chain from the extraction of minerals to the delivery of product to our customers. Linked
to this is the importance of internal control in helping to expose and improve underperforming internal operations.
Finally, internal control systems are essential in providing information for internal and external reporting upon which, in
turn, investor confidence rests.
(ii) Proposals to improve internal systems at WM
As you may be aware, mineral estimation and measurement can be problematic, particularly in some regions. Indeed,
there are several factors that can lead to under or overestimation of reserves valuations as a result of geological survey
techniques and regional cultural/social factors. In the case of mallerite, however, the issues that have been brought to
the board’s attention are matters of internal control and it is to these that I would now like to turn.
In first instance, it is clear from the fact that the overestimate was made that we will need to audit geological reports at
an appropriate (and probably lower) level in the organisation in future.
Once a claim has been made about a given mineral resource level, especially one upon which investor returns might
depend, appropriate systems will be instituted to ask for and obtain evidence that such reserves have been correctly and
accurately quantified.
We will recognise that single and verbal source reports of reserve quantities may not necessarily be accurate. This was
one of the apparent causes of the overestimation of mallerite. A system of auditing actual reserves rather than relying
on verbal evidence will rectify this.
The purchase of any going concern business, such as the mallerite mine, is subject to due diligence. WM will be
examining its procedures in this area to ensure that they are fit for purpose in the way that they may not have been in
respect of the purchase of the mallerite mine. I will be taking all appropriate steps to ensure that all of these internal
control issues can be addressed in future.
Thank you for your continued support of Worldwide Minerals and I hope the foregoing goes some way to reassure you
that the company places the highest value on its investors and their loyalty.
Yours faithfully,
Tim Blake
Chairman

正确答案：
(ii) Corporate hospitality
A partner in an audit firm is obviously in a position to influence the conduct and outcome of an audit. Therefore a
partner being on ‘too friendly’ terms with an audit client creates a familiarity threat. Other members of the audit team
may not exert as much influence on the audit.
A self-interest threat may also be perceived (e.g. if corporate hospitality is provided to keep a prestigious client).
There is no absolute prohibition against corporate hospitality provided:
■ the value attached to such hospitality is ‘insignificant’; and
■ the ‘frequency, nature and cost’ of the hospitality is reasonable.
Thus, flying the directors of an audit client for weekends away could be seen as significant. Similarly, entertaining an
audit client on a regular basis could be seen as unacceptable.
Partners and staff of Boleyn will need to be objective in their assessments of the significance or reasonableness of the
hospitality offered. (Would ‘a reasonable and informed third party’ conclude that the hospitality will or is likely to be
seen to impair your objectivity?)
If they have any doubts they should discuss the matter in the first instance with the audit engagement partner, who
should refer the matter to the ethics partner if in doubt.

正确答案：

(a) Fraud responsibility

Maple & Co must conduct an audit in accordance with ISA 240 The Auditor’s Responsibilities Relating to Fraud in an Audit of Financial Statements and are responsible for obtaining reasonable assurance that the financial statements taken as a whole are free from material misstatement, whether caused by fraud or error.

In order to fulfil this responsibility, Maple & Co is required to identify and assess the risks of material misstatement of the financial statements due to fraud.

They need to obtain sufficient appropriate audit evidence regarding the assessed risks of material misstatement due to fraud, through designing and implementing appropriate responses. In addition, Maple & Co must respond appropriately to fraud or suspected fraud identified during the audit.

When obtaining reasonable assurance, Maple & Co is responsible for maintaining professional scepticism throughout the audit, considering the potential for management override of controls and recognising the fact that audit procedures which are effective in detecting error may not be effective in detecting fraud.

To ensure that the whole engagement team is aware of the risks and responsibilities for fraud and error, ISAs require that a discussion is held within the team. For members not present at the meeting, Sycamore’s audit engagement partner should determine which matters are to be communicated to them.

(b) Audit risks and auditors’ responses

(c) (i) Review engagements

Review engagements are often undertaken as an alternative to an audit, and involve a practitioner reviewing financial data, such as six-monthly figures. This would involve the practitioner undertaking procedures to state whether anything has come to their attention which causes the practitioner to believe that the financial data is not in accordance with the financial reporting framework.

A review engagement differs to an external audit in that the procedures undertaken are not nearly as comprehensive as those in an audit, with procedures such as analytical review and enquiry used extensively. In addition, the practitioner does not need to comply with ISAs as these only relate to external audits.

(ii) Levels of assurance

The level of assurance provided by audit and review engagements is as follows:

External audit – A high but not absolute level of assurance is provided, this is known as reasonable assurance. This provides comfort that the financial statements present fairly in all material respects (or are true and fair) and are free of material misstatements.

Review engagements – where an opinion is being provided, the practitioner gathers sufficient evidence to be satisfied that the subject matter is plausible; in this case negative assurance is given whereby the practitioner confirms that nothing has come to their attention which indicates that the subject matter contains material misstatements.
