You are an audit supervisor of Pluto & Co and are currently planning the audit of your client, Venus Magnets Co (Venus) which manufactures decorative magnets. Its year end is 31 December 2015 and the forecast profit before tax is $9·6 million.
During the year, the directors reviewed the useful lives and depreciation rates of all classes of plant and machinery. This resulted in an overall increase in the asset lives and a reduction in the depreciation charge for the year.
Inventory is held in five warehouses and on 28 and 29 December a full inventory count will be held with adjustments for movements to the year end. This is due to a lack of available staff on 31 December. In October, there was a fire in one of the warehouses; inventory of $0·9 million was damaged and this has been written down to its scrap value of $0·2 million. An insurance claim has been submitted for the difference of $0·7 million. Venus is still waiting to hear from the insurance company with regards to this claim, but has included the insurance proceeds within the statement of profit or loss and the statement of financial position.
The finance director has informed the audit manager that the October and November bank reconciliations each contained unreconciled differences; however, he considers the overall differences involved to be immaterial.
A directors’ bonus scheme was introduced during the year which is based on achieving a target profit before tax. In order to finalise the bonus figures, the finance director of Venus would like the audit to commence earlier so that the final results are available earlier this year.
Required:
Describe FIVE audit risks, and explain the auditor’s response to each risk, in planning the audit of Venus Magnets Co.

Bosses now prefer to be paid in share options. The average chief executive of one of America's top 200 firms would take home just over $750,000 in gold. In fact, in 1998 he made a pre-tax profit of $8.3 m by exercising executive share options, which give the right to buy a fixed number of his company's shares at a fixed price in what is now a rising market. At the end of last year, he also had total unrealized profits on stock options of nearly $50m.
But put to one side questions of justice and inequality. Force down the thought that the chief executive's enormous share options may demoralize the deputy chief executive and make the company harder to manage. Ignore the bleating bondholder, who sees his risk rise as companies borrow to buy back shares to give to executives. The fundamental question is whether share-option schemes are doing what they were designed to do: aligning the interests of managers with those of owners, motivating bosses to do their level best by shareholders.

Caution seems the watchword among the institutional investors surveyed in our latest portfolio poll. The allocation of money between equities, bonds and cash has, on average, remained at the same levels as it did during the third quarter. While Lehman Brothers and Commerz International have increased their overall equity allocations, Daiwa has increased its bond allocation. But given the slowdown in the American economy, it is the reaction of our investors to American equity holdings that is worthy of note.
While three of them, including Lehman Brothers, take a dim view of the prospects for American shares, the other four have either marginally increased their allocations, or have maintained them at the same levels as in the previous quarter. Lehman Brothers seems to have decided that the prospect for German shares is better than it is for American ones. Its allocation for American equities dropped by seven percentage points, to 45% of its equity holdings; while its German share portfolio increased by six percentage points, to 11%. Lehman's share allocation to America has dropped, even as its overall equity holdings have increased.
Daiwa and Standard Life are the other two that have cut back on American equities. But Credit Suisse continues to be a cheerleader for American shares. Following its ten percentage-point increase in the third quarter, the Swiss firm increased its exposure to American equities once again in the fourth quarter. Commerz International appears to share Credit Suisse's bullish outlook: its American equity holdings have increased by four percentage points, to 490. Julius Baer is extremely bullish on American equities, with 60% of its equity funds parked there. But the average American equity holdings, among our institutional investors dropped by a percentage point in the fourth quarter.
British equities seem to have become attractive—all our investors have increased their allocations. Credit Suisse, which in the third quarter cut its investment in British shares, appears to have changed its mind. It has increased its allocation by four percentage points, taking the total to 9%. On the other hand, Japanese shares have been given the thumbs-down: all our investors save Julius Baer (unchanged) and Credit Suisse (slightly up) have moved funds out of Japanese equities.
It is a relatively similar story for Japanese bonds, where everybody apart from Commerz International has either dropped their yen-denominated bond holdings, or kept them unchanged. Robeco Group seems decidedly bearish, for it has sharply, cut its allocation, from 24% to 15%. Lehman Brothers, appears to have got the timing right, by raising its allocation of dollar-denominated bonds in the fourth quarter. Its increase was followed by the Fed interest-rate cut on January 3rd. Will Lehman's bearish timing prove right for American shares, too？
Lehman Brothers______.
A．has increased its equity and bond allocation in America
B．pays less attention to the equity holdings because of the American economy's slowdown
C．is pessimistic about the American prospect and cautious about its allocation
D．is as bearish as other institutional investors
