(b) Outsourced cold storage
(i) Matters
■ Inventory at 31 March 2007 represents 21% of total assets (10·1/48·0) and is therefore a very material item in the
balance sheet.
■ The value of inventory has increased by 50% though revenue has increased by only 7·5%. Inventory may be
overvalued if no allowance has been made for slow-moving/perished items in accordance with IAS 2 Inventories.
■ Inventory turnover has fallen to 6·6 times per annum (2006 – 9·3 times). This may indicate a build up of
unsaleable items.
Tutorial note: In the absence of cost of sales information, this is calculated on revenue. It may also be expressed
as the number of days sales in inventory, having increased from 39 to 55 days.
■ Inability to inspect inventory may amount to a limitation in scope if the auditor cannot obtain sufficient audit
evidence regarding quantity and its condition. This would result in an ‘except for’ opinion.
■ Although Hogg’s monthly return provides third party documentary evidence concerning the quantity of inventory it
does not provide sufficient evidence with regard to its valuation. Inventory will need to be written down if, for
example, it was contaminated by the leakage (before being moved to Hogg’s cold storage) or defrosted during
transfer.
■ Lamont’s written representation does not provide sufficient evidence regarding the valuation of inventory as
presumably Lamont’s management did not have access to physically inspect it either. If this is the case this may
call into question the value of any other representations made by management.
■ Whether, since the balance sheet date, inventory has been moved back from Hogg’s cold storage to Lamont’s
refrigeration units. If so, a physical inspection and roll-back of the most significant fish lines should have been
undertaken.
Tutorial note: Credit will be awarded for other relevant accounting issues. For example a candidate may question
whether, for example, cold storage costs have been capitalised into the cost of inventory. Or whether inventory moves
on a FIFO basis in deep storage (rather than LIFO).
(ii) Audit evidence
■ A copy of the health and safety regulation preventing the auditor from gaining access to Hogg’s cold storage to
inspect Lamont’s inventory.
■ Analysis of Hogg’s monthly returns and agreement of significant movements to purchase/sales invoices.
■ Analytical procedures such as month-on-month comparison of gross profit percentage and inventory turnover to
identify any trend that may account for the increase in inventory valuation (e.g. if Lamont has purchased
replacement inventory but spoiled items have not been written off).
■ Physical inspection of any inventory in Lamont’s refrigeration units after the balance sheet date to confirm its
condition.
■ An aged-inventory analysis and recalculation of any allowance for slow-moving items.
■ A review of after-date sales invoices for large quantities of fish to confirm that fair value (less costs to sell) exceed
carrying amount.
■ A review of after-date credit notes for any returns of contaminated/perished or otherwise substandard fish.

正确答案：
(c) There are many reasons that could be discussed in support of the view that net present value (NPV) is superior to other
investment appraisal methods.
NPV considers cash flows
This is the reason why NPV is preferred to return on capital employed (ROCE), since ROCE compares average annual
accounting profit with initial or average capital invested. Financial management always prefers cash flows to accounting profit,
since profit is seen as being open to manipulation. Furthermore, only cash flows are capable of adding to the wealth of
shareholders in the form. of increased dividends. Both internal rate of return (IRR) and Payback also consider cash flows.
NPV considers the whole of an investment project
In this respect NPV is superior to Payback, which measures the time it takes for an investment project to repay the initial
capital invested. Payback therefore considers cash flows within the payback period and ignores cash flows outside of the
payback period. If Payback is used as an investment appraisal method, projects yielding high returns outside of the payback
period will be wrongly rejected. In practice, however, it is unlikely that Payback will be used alone as an investment appraisal
method.
NPV considers the time value of money
NPV and IRR are both discounted cash flow (DCF) models which consider the time value of money, whereas ROCE and
Payback do not. Although Discounted Payback can be used to appraise investment projects, this method still suffers from the
criticism that it ignores cash flows outside of the payback period. Considering the time value of money is essential, since
otherwise cash flows occurring at different times cannot be distinguished from each other in terms of value from the
perspective of the present time.
NPV is an absolute measure of return
NPV is seen as being superior to investment appraisal methods that offer a relative measure of return, such as IRR and ROCE,
and which therefore fail to reflect the amount of the initial investment or the absolute increase in corporate value. Defenders
of IRR and ROCE respond that these methods offer a measure of return that is understandable by managers and which can
be intuitively compared with economic variables such as interest rates and inflation rates.
NPV links directly to the objective of maximising shareholders’ wealth
The NPV of an investment project represents the change in total market value that will occur if the investment project is
accepted. The increase in wealth of each shareholder can therefore be measured by the increase in the value of their
shareholding as a percentage of the overall issued share capital of the company. Other investment appraisal methods do not
have this direct link with the primary financial management objective of the company.
NPV always offers the correct investment advice
With respect to mutually exclusive projects, NPV always indicates which project should be selected in order to achieve the
maximum increase on corporate value. This is not true of IRR, which offers incorrect advice at discount rates which are less
than the internal rate of return of the incremental cash flows. This problem can be overcome by using the incremental yield
approach.
NPV can accommodate changes in the discount rate
While NPV can easily accommodate changes in the discount rate, IRR simply ignores them, since the calculated internal rate
of return is independent of the cost of capital in all time periods.
NPV has a sensible re-investment assumption
NPV assumes that intermediate cash flows are re-invested at the company’s cost of capital, which is a reasonable assumption
as the company’s cost of capital represents the average opportunity cost of the company’s providers of finance, i.e. it
represents a rate of return which exists in the real world. By contrast, IRR assumes that intermediate cash flows are reinvested
at the internal rate of return, which is not an investment rate available in practice,
NPV can accommodate non-conventional cash flows
Non-conventional cash flows exist when negative cash flows arise during the life of the project. For each change in sign there
is potentially one additional internal rate of return. With non-conventional cash flows, therefore, IRR can suffer from the
technical problem of giving multiple internal rates of return.
