考题 5 The directors of Blaina Packaging Co (BPC), a well-established manufacturer of cardboard boxes, are currentlyconsidering whether to enter the cardboard tube market. Cardboard tubes are purchased by customers whoseproducts are wound around tubes of various sizes ranging from large tubes on which carpets are wound, to smalltubes around which films and paper products are wound. The cardboard tubes are usually purchased in very largequantities by customers. On average, the cardboard tubes comprise between 1% and 2% of the total cost of thecustomers’ 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 ispriced at $30,000 and requires only one operative for its operation. A one-day training course is required in orderthat 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 inshort supply.(3) At present, four major manufacturers of cardboard tubes have an aggregate market share of 80%. The currentmarket leader has a 26% market share. The market shares of the other three major manufacturers, one of whichis JOL Co, are equal in size. The product ranges offered by the four major manufacturers are similar in terms ofsize 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 beinggiven to expanding operations in their packaging division overseas. The division possesses large-scale automatedmachinery 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 arecapable of housing small products such as film and paper-based products. At present, these tubes are on average30% 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 cardboardtubes as a performance improvement strategy for BPC.

考题 (b) You are an audit manager with specific responsibility for reviewing other information in documents containingaudited financial statements before your firm’s auditor’s report is signed. The financial statements of Hegas, aprivately-owned civil engineering company, show total assets of $120 million, revenue of $261 million, and profitbefore tax of $9·2 million for the year ended 31 March 2005. Your review of the Annual Report has revealedthe 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 thisamount or ‘other difference’ elsewhere in the financial statements. However, the Management Report, whichis required by statute, is not audited. It discloses that ‘changes in shareholders’ equity not recognized inincome 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 asignificant 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 largestgenerators of hydro-electricity, with a dedicated commitment to accountable ethical professionalism’. Auditworking papers show that 14% of revenue was derived from hydro-electricity (2004: 12%). Publiclyavailable 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 financialstatements of Hegas for the year ended 31 March 2005.

考题 问答题Most people would describe water like a colorless liquid. They         (1) _______would know that in very cold conditions it becomes a solid calledice and that when heating on a fire it becomes a vapor called steam.       (2) _______However, water, they would say, is a liquid. We have learned thatwater consists of molecules composed with two atoms of hydrogen          (3) _______and one atom of oxygen, which we describe by the formula H2O.This is equally true of the solid called ice and the gas called steam.Chemically there is no difference between the gas, the liquid, andthe solid, all of which is made up of molecules with the formula H2O.       (4) _______This is true of other chemical substances; most of them can exist asgases or as liquids or as solids. We may normally think of iron as asolid, but if we will heat it in a furnace, it will melt and become a       (5) _______liquid, and at very high temperatures it will become a gas. Nothingvery permanent occurs when a gas changes into a liquid or a solid.Everyone knows that ice, which has been made by freezing water,can be melted again by warmed and that steam can be condensed           (6) _______on a cold surface to become liquid water. In fact, it is only becausewater is so a familiar substance that different names are used for        (7) _______the solid, liquid and gas. Most substances are only familiar with         (8) _______us in one state, because the temperatures requiring to turn them         (9) _______into gases are very high, or the temperatures necessary to turn theminto solids are so low. Water is an exception in this respect, whichis another reason why its three states have given three different        (10) _______names.
