(b) You are an audit manager with specific responsibility for reviewing other information in documents containing
audited financial statements before your firm’s auditor’s report is signed. The financial statements of Hegas, a
privately-owned civil engineering company, show total assets of $120 million, revenue of $261 million, and profit
before tax of $9·2 million for the year ended 31 March 2005. Your review of the Annual Report has revealed
the following:
(i) The statement of changes in equity includes $4·5 million under a separate heading of ‘miscellaneous item’
which is described as ‘other difference not recognized in income’. There is no further reference to this
amount or ‘other difference’ elsewhere in the financial statements. However, the Management Report, which
is required by statute, is not audited. It discloses that ‘changes in shareholders’ equity not recognized in
income includes $4·5 million arising on the revaluation of investment properties’.
The notes to the financial statements state that the company has implemented IAS 40 ‘Investment Property’
for the first time in the year to 31 March 2005 and also that ‘the adoption of this standard did not have a
significant impact on Hegas’s financial position or its results of operations during 2005’.
(ii) The chairman’s statement asserts ‘Hegas has now achieved a position as one of the world’s largest
generators of hydro-electricity, with a dedicated commitment to accountable ethical professionalism’. Audit
working papers show that 14% of revenue was derived from hydro-electricity (2004: 12%). Publicly
available information shows that there are seven international suppliers of hydro-electricity in Africa alone,
which are all at least three times the size of Hegas in terms of both annual turnover and population supplied.
Required:
Identify and comment on the implications of the above matters for the auditor’s report on the financial
statements of Hegas for the year ended 31 March 2005. (10 marks)

5 The directors of Blaina Packaging Co (BPC), a well-established manufacturer of cardboard boxes, are currently
considering whether to enter the cardboard tube market. Cardboard tubes are purchased by customers whose
products are wound around tubes of various sizes ranging from large tubes on which carpets are wound, to small
tubes around which films and paper products are wound. The cardboard tubes are usually purchased in very large
quantities by customers. On average, the cardboard tubes comprise between 1% and 2% of the total cost of the
customers’ finished product.
The directors have gathered the following information:
(1) The cardboard tubes are manufactured on machines which vary in size and speed. The lowest cost machine is
priced at $30,000 and requires only one operative for its operation. A one-day training course is required in order
that an unskilled person can then operate such a machine in an efficient and effective manner.
(2) The cardboard tubes are made from specially formulated paper which, at times during recent years, has been in
short supply.
(3) At present, four major manufacturers of cardboard tubes have an aggregate market share of 80%. The current
market leader has a 26% market share. The market shares of the other three major manufacturers, one of which
is JOL Co, are equal in size. The product ranges offered by the four major manufacturers are similar in terms of
size and quality. The market has grown by 2% per annum during recent years.
(4) A recent report on the activities of a foreign-based multinational company revealed that consideration was being
given to expanding operations in their packaging division overseas. The division possesses large-scale automated
machinery for the manufacture of cardboard tubes of any size.
(5) Another company, Plastic Tubes Co (PTC) produces a narrow, but increasing, range of plastic tubes which are
capable of housing small products such as film and paper-based products. At present, these tubes are on average
30% more expensive than the equivalent sized cardboard tubes sold in the marketplace.
Required:
(a) Using Porter’s five forces model, assess the attractiveness of the option to enter the market for cardboard
tubes as a performance improvement strategy for BPC. (10 marks)
