    INSIGHT

    FOREWORDFOREWORDThis issue of INSIGHT is published principally, in response to a growing

    demand, as an aid to:

    (i) Candidates preparing to write future examinations of theInstitute of Chartered Accountants of Nigeria (ICAN) at anequivalent level;

    (ii) Unsuccessful candidates in the identification of thoseareas in which they lost marks and need to improve theirknowledge and presentation;

    (iii) Lecturers and students interested in acquisition ofknowledge in the relevant subjects contained therein; and

    (iv) The profession in improving pre-examination screeningprocesses, and also the professional performance.

    The answers provided in this book do not exhaust all possible alternative

    approaches to solving the questions. Efforts have been made to use

    methods, which will save much of the scarce examination time.

    It is hoped that the suggested answers will prove to be of tremendous

    assistance to students and those who assist them in their preparations for

    the Institutes Examinations.

    from incomplete records was attempted by 70% of the candidates. They

    a An enterprise shall disclose the summary of significant

    accounting policies or other notes and judgments made in the

    preparation of the financial statements

    b The amount of dividend proposed before the financial statements

    were authorized for issue but not recognized as distribution to

    shareholders during the period and the related amount per

    share.

    C The amount of any cumulative preference dividend not

    recognized

    f The name of the parent and ultimate parent of the group

    ii) Disclosure of accounting policies by quoted companies is considered to

    be desirable because:

    In preparing financial statements there is a high degree of

    subjectivity involved. By disclosing accounting policies the reader

    of the financial statements is being provided with useful and

    relevant information. Therefore, investors have more information

    upon which to base their decisions of whether to buy, sell or hold a

    companys shares.

    In comparing different companies the potential investors may be

    able to adjust the profit figures to ensure comparability between thecompanies if the accounting policies are stated.

    It may attempt to stop the use of creative accounting if the

    company is having to disclose its accounting policies for example if

    a company alters its method of valuing stock in order to increase its

    profit for the year.

    By informing the readers of the financial statements of a change in

    any of its accounting policies the company might be very reluctantto carry out this change.

    iii) Example of circumstances not considered as change in accounting

    policies:

    A change in the rate at which depreciation is calculated arising from a

    re-appraisal of the useful or economic life of an asset.

    The adoption of an accounting policy for a transaction either notpreviously dealt in or which was preciously not a significant part of the

    business of an enterprise:

    EXAMINERS COMMENT

    The question which tests the candidates understanding of Trading Profit and

    Loss Account was attempted by 98% of the candidates, and goods marks

    were scored. About 20% of them could not understand the difference

    between returns outwards and returns inwards. In effect they were wrongly

    treated in the accounts prepared.

    SOLUTION 4

    a) The advantages of Value Added Statement over the profit and Loss

    Account are:

    i) It can be used as a better negotiation tool by employees, than

    the Profit and Loss Account

    ii) It reveals the effort contributed by employees in the operation of

    an enterprise and how they were rewarded. Value Added

    Statement shows the percentage enjoyed by employees out of

    the wealth created.

    iii) It demonstrates the efficiency of capital and labour employed in

    creating the additional wealth of the organization. Whereas the

    Profit and Loss Account assumes that the beneficial interests of

    an enterprise belong to the owner.iv) It shows that a business enterprise exist for the benefit of the

    Society at large, whereas, the Profit and Loss Account assumes

    that the beneficial interests of an enterprise belong to the owner.

    v) It can easily be understood than the Profit and Loss Account.

    The question is on bar charts. All the various forms of bar charts are testedin the question. Some candidates had difficulty in distinguishing between a

    component bar chart and a percentage component bar chart. Some were

    also confusing multiple bar chart with either component bar chart or

    percentage component bar chart. A reasonable number of candidates did

    fairly well in answering the question. On the average, the performance of

    the candidates was fair.

    EXAMINERS COMMENT

    Estimating mode from a Histogram and calculating mean, standard deviation

    and coefficient of variation are the subject matter of question. Virtually, allcandidates attempted the question and the performance was generally good.

    The major pitfall was the inability of some candidates in recalling the correct

    formula for calculating the standard deviation of grouped data. The use of

    class boundaries as the axis of the histogram posed a big challenge to some

    candidates.

    EXAMINERS COMMENT

    The main difference between this question and Question 2 is in the area of

    candidates being required to calculate the coefficient of skewness.

    Candidates are expected to know that the nearer to zero the coefficient of

    skewness is, the nearer the distribution will be to being symmetric. The

    major pitfall of the candidates was the inability to recall the correct

    expression for the coefficient of skewness. Generally, the overall

    performance was fair.

    EXAMINERS COMMENT

    Condition for a company to break even and maximizing profit concept are

    tested in the question. Candidates are expected to know that a companys

    profit is maximized when the marginal revenue equals the marginal cost,

    and that the company breaks even when the profit or loss is zero. The major

    pitfall of some of the candidates was their getting the concept of break

    even wrong. Some of them thought that company breaks even when the

    EXAMINERS COMMENT

    This is testing candidates knowledge on matrix formulation. Candidates are

    expected to obtain the inverse of a matrix based on determinant, and adjoint

    of the matrix. Candidates are expected to know that the transpose of the

    matrix of cofactors of the matrix is its adjoint and the inverse of the matrix is

    its adjoint divided by its determinant. Inability of some of the candidates to

    compute the matrix of cofactors was the major pitfall. The performance was

    generally fair. A number of candidates could not formulate the given worded

    problem in a matrix form i.e AX = B

    This question is on Network Analysis based on the activity-on-arrow format.

    The major pitfall was that some candidates did not show arrows in the

    EXAMINERS COMMENT

    Linear Programming via graphical solution is the subject matter of the

    question. The major pitfall of the candidates is in the formulation of the

    given worded problem as a linear programming problem. Most of the

    candidates did not state the non-negativity condition. Genera
