  • 第1题:

    (b) Explain the matters that should be considered when planning the nature and scope of the examination of

    Cusiter Co’s forecast balance sheet and income statement as prepared for the bank. (7 marks)


    正确答案:
    (b) Matters to be considered
    Tutorial note: Candidates at this level must appreciate that the matters to be considered when planning the nature and
    scope of the examination are not the same matters to be considered when deciding whether or not to accept an
    engagement. The scenario clearly indicates that the assignment is being undertaken by the current auditor rendering any
    ‘pre-engagement’/‘professional etiquette’ considerations irrelevant to answering this question.
    This PFI has been prepared to show an external user, the bank, the financial consequences of Cusiter’s plans to help the bank
    in making an investment decision. If Cusiter is successful in its loan application the PFI provides a management tool against
    which the results of investing in the plant and equipment can be measured.
    The PFI is unpublished rather than published. That is, it is prepared at the specific request of a third party, the bank. It will
    not be published to users of financial information in general.
    The auditor’s report on the PFI will provide only negative assurance as to whether the assumptions provide a reasonable basis
    for the PFI and an opinion whether the PFI is:
    ■ properly prepared on the basis of the assumptions; and
    ■ presented in accordance with the relevant financial reporting framework.
    The nature of the engagement is an examination to obtain evidence concerning:
    ■ the reasonableness and consistency of assumptions made;
    ■ proper preparation (on the basis of stated assumptions); and
    ■ consistent presentation (with historical financial statements, using appropriate accounting principles).
    Such an examination is likely to take the form. of inquiry, analytical procedures and corroboration.
    The period of time covered by the prospective financial information is two years. The assumptions for 2008 are likely to be
    more speculative than for 2007, particularly in relation to the impact on earnings, etc of the investment in new plant and
    equipment.
    The forecast for the year to 31 December 2007 includes an element of historical financial information (because only part of
    this period is in the future) hence actual evidence should be available to verify the first three months of the forecast (possibly
    more since another three-month period will expire at the end of the month).
    Cusiter management’s previous experience in preparing PFI will be relevant. For example, in making accounting estimates
    (e.g. for provisions, impairment losses, etc) or preparing cash flow forecasts (e.g. in support of the going concern assertion).
    The basis of preparation of the forecast. For example, the extent to which it comprises:
    ■ proforma financial information (i.e. historical financial information adjusted for the effects of the planned loan and capital
    expenditure transaction);
    ■ new information and assumptions about future performance (e.g. the operating capacity of the new equipment, sales
    generated, etc).
    The nature and scope of any standards/guidelines under which the PFI has been prepared is likely to assist the auditor in
    discharging their responsibilities to report on it. Also, ISAE 3400 The Examination of Prospective Financial Information,
    establishes standards and provides guidance on engagements to examine and report on PFI including examination
    procedures.
    The planned nature and scope of the examination is likely to take into account the time and fee budgets for the assignments
    as adjusted for any ‘overlap’ with audit work. For example, the examination of the PFI is likely to draw on the auditor’s
    knowledge of the business obtained in auditing the financial statements to 31 December 2006. Analytical procedures carried
    out in respect of the PFI may provide evidence relevant to the 31 December 2007 audit.

  • 第4题:

    根据下列材料请回答 31~35 题:

    A

    Now satellites are helping to forecast the weather.They are in space,and they can reach any part of the world.The satellites take pictures of the atmosphere(大气),because this is where the weather form.They send these pictures to the weather stations.So meteorologists(气象学家)can see the weather of any part of the world.From the pictures,the scientists can often say how the weather will change.

    Today,nearly five hundred weather stations in sixty countries receive satellite pictures.When they receive new pictures,the meteorologists compare them with earlier ones.Perhaps they may find that the clouds have changed during the last few hours.This may mean that the weather on the ground may soon change,too.In their next weather forecast,the meteorologists can say this.

    So the weather satellites are a great help to the meteorologists.Before satellites were invented,the scientists could forecast the weather for about 24 0r 48 hours.Now they can make good forecasts for three or five days.Soon,perhaps,they may be able to forecast the weather for a week or more ahead.

    Forecasting Methods

    There are several different methods that can be used to create a forecast. The method a forecaster chooses
    depends upon the experience of the forecaster,the amount of information available to the forecaster,the level of
    difficulty that the forecast situation presents,and the degree of accuracy or confidence needed in the forecast.
    The first of these methods is the persistence method,the simplest way of producing a forecast.The per-
    sistence method assumes that the conditions at the time of the forecast will not change.For example,if it is
    sunny and 87 degrees today,the persistence method predicts that it will be sunny and 87 degrees tomorrow.
    If two inches of rain fell today,the persistence method would predict two inches of rain for tomorrow.
    However,if weather conditions change significantly from day to day,the persistence method usually breaks
    down and is not the best forecasting method to use.
    The trends method involves determining the speed and direction of movement for fronts,high and low
    pressure centers , and areas of clouds and precipitation(降水量).Using this information , the forecaster can
    predict where he or she expects those features to be at some future time.For example,if a storm system is
    1,000 miles west of your location and moving to the east at 250 miles per day,using the trends method you
    would predict it arrive in your area in 4 days.The trends method works well when systems continue to move
    at the same speed in the same direction for a long period of time.If they slow down,speed up,change intensi-
    ty,or change directions,the trends forecast will probably not work as well.
    The climatology(气候学)method is another simple way of producing a forecast. This method involves
    averaging weather statistics accumulated over many years to make the forecast.For example,if you were using
    the climatology method to predict the weather for New York City on July 4th,you would go through all the
    weather data that has been recorded for every July 4th and take an average.The climatology method oniy
    works well when the weather pattern is similar to that expected for the chosen time of year. If the pattern is
    quite unusual for the given time of year,the climatology method will often fail.
    The analog method is a slightly more complicated method of producing a forecast.It involves examining
    today's forecast scenario(模式)and remembering a day in the past when the weather scenario looked very
    similar(an analog).The forecaster would predict that the weather in this forecast will behave the same as ii
    did in the past.The analog method is difficult to use because it is virtually impossible to find a predict ana-
    log.Various weather features rarely align themselves in the same locations as they were in the previous time.
    Even small differences between the current time and the analog can lead to very different results.

    The persistence method fails to work well when_________.
    A:it is rainy
    B:it is sunny
    C:weather conditions change greatly
    D:weather conditions stay stable

    答案:C
    解析:
