第25题: [简答题]
In the context of corporate governance explain the role of the external company auditors, paying particular regard to the following issues:(a) their qualifications;(b) their powers;(c) their duties. (10 marks)
参考答案:  This question requires candidates to consider the crucially important role of the auditor in relation to companies and the way in which the behaviour of such businesses function and are overseen. The corporate governance structure specifies the distribution of rights and responsibilities among different participants in the corporation, such as, the board, managers, shareholders and other stakeholders, and spells out the rules and procedures for making decisions on corporate affairs. Auditors have an extremely important role to play in that regard: they are appointed to ensure that the interests of the shareholders in a company are being met. Their key function is to produce independent and authoriative reports confirming, or otherwise, that the accountancy information provided to shareholders is reliable. The law relating to company auditors is to be found in ss.CHD–CID Companies Act (CA) AIHE as altered by CA AIHI. Even where a company has passed an elective resolution to dispense with laying accounts, the accounts are still required to be prepared, audited and circulated. Consequently every company, only excepting dormant private companies, is required to appoint an auditor, who must be appropriately qualified and in other respects eligible (s.CHD(A) CA AIHE). Qualifications The essential requirement for any person to act as a company auditor is that they are, eligible under the rules, and a member of, a recognised supervisory body (s.BE CA AIHI). This in turn requires them to hold a professional accountancy qualification. ‘Supervisory bodies’ are ones established in the UK to control the eligibility of potential company auditors and the quality of their operation (s.C0 CA AIHI). The recognised supervisory bodies are: (a) the Institute of Chartered Accountants in England and Wales; (b) the Institute of Chartered Accountants of Scotland; (c) the Institute of Chartered Accountants in Ireland; (d) the Association of Chartered Certified Accountants; and (e) the Association of Authorised Public Accountants. The first four bodies mentioned above are also recognised as ‘qualifying bodies’, meaning that accountancy qualifications awarded by them are recognised professional qualifications for auditing purposes. There still is the small possibility of unqualified but appropriately experienced individuals acting as auditors in relation to what used to be known as ‘exempt private companies’ (s.C CA AIHI). A person is ineligible for appointment as auditor if they are either: (a) an officer or employee of the company (the auditor being specifically declared not to be an officer or employee); and/or (b) a partner or employee of a person in (i) above, or is a partnership of which such a person is a partner (CA AIHI, s.BG). It is a criminal offence to act while ineligible. Appointment and removal Auditors are appointed annually (s.CHE CA AIHE), generally, at each annual general meeting. Where a company has passed an elective resolution to dispense with the annual reappointment of auditors, they are, nonetheless, deemed to be re-appointed automatically for each year. The first auditors are usually appointed by the directors or, in default, by the company in general meetings (s.CHE CA AIHE). The first auditors hold office until the conclusion of the first meeting at which accounts are laid, although they can, of course, be re-elected. If auditors are not appointed, or re-appointed, then the Secretary of State may appoint auditors to act (s.CHG(A) CA AIHE). Under the Combined Code on Corporate Governance, a company’s audit committee must be involved in the appointment and dismissal of both the external and internal auditors. Audit committees must have annual procedures to ensure the independence and objectivity of the external auditor which should involve a consideration of all relationships between the company and the firm carrying out the external audit. An auditor may be removed at any time by an ordinary resolution of the company (s.CIA(A)). This does, however, require special notice. Any auditor who is to be removed or not re-appointed is entitled to make written representations and require these to be circulated or have them read out at the meeting (s.CIAA CA AIHE). An auditor may resign at any time (s.CIB CA AIHE). Notice of resignation must be accompanied by a statement of any circumstances that the auditor believes ought to be brought to the attention of members and creditors (payables), or alternatively a statement that there are no such circumstances (s.CID CA AIHE). The company is required to file a copy of the notice with the registrar of companies within AD days (s.CIB CA AIHE). Where the auditor’s resignation statement states that there are circumstances that should be brought to the attention of members, then he may require the company to call a meeting to allow an explanation of those circumstances to the members of the company (s.CIBA(A) CA AIHE). Rights and duties The auditors have the right of access at all times to the company’s books and accounts, and officers of the company are required to provide such information and explanations as the auditors consider necessary (s.CHIA CA AIHE). It is a criminal offence to make false or reckless statements to auditors (s.CHIA CA AIHE). It should be noted that the Companies (Audit, Investigations And Community Enterprise) Act B00D (C(AICE)A) significantly strengthened the power of auditors. Under s.CHIA of the Companies Act AIHE a company’s auditors were entitled to require from the company’s officers such information and explanations as they thought necessary for the performance of their duties as auditors. It always was a criminal offence for an officer of the company to provide misleading, false or deceptive information or explanations. However, it was not an offence for them to fail to provide any information or explanation that the auditors required of them. That anomaly has been remedied by the C(AICE)A as follows:– s.H of C(AICE)A makes it a criminal offence to fail to provide information or explanations required by the auditor;– s. H also entitles the auditor to require information and explanations from a wider group of people than merely the officers of the company. Consequently employees may now be subject to the auditor’s authority;– subsection H(D) makes it an offence for a parent company to fail to take all steps reasonably open to it to obtain the information or explanations which the auditor has required it to obtain from its non-UK subsidiary and those associated with it; and the offence applies also to any officer of the company who knowingly and wilfully authorises or permits the failure;– s.I requires that Directors’ Reports must contain a statement that the directors are not aware of relevant information which has not been disclosed to the company’s auditors. The directors are placed under the duty to ensure that they have taken all the steps they should have taken as a director to make themselves aware of such information and to establish that the auditors are aware of it. It will be a criminal offence to issue a false statement. The stated purpose of s.I is to ensure that each director will have to think hard about whether there is any information that they know about or could ascertain which is needed by the auditors in connection with preparing their report. Auditors are entitled to receive notices and other documents in connection with all general meetings, to attend such meetings and to speak when the business affects their role as auditors (s.CI0 CA AIHE). Where a company operates on the basis of written resolutions rather than meetings, then the auditor is entitled to receive copies of all such proposed resolutions as are to be sent to members (s.CHAB CA AIHE). Auditors are required to make a report on all annual accounts laid before the company in a general meeting during their tenure of office (s.BCE CA AIHE). They are specifically required to report on certain issues: (a) whether the accounts have been properly prepared in accordance with the Act; and (b) whether the individual and group accounts show a true and fair view of the profit or loss and state of affairs of the company and of the group, so far as concerns the members of the company; (c) whether the information in the Directors’ Report is consistent with the accounts presented. Under s.BCG CA AIHE auditors are required to investigate: (a) whether the company has kept proper accounting records and obtained proper accounting returns from branches. (b) whether the accounts are in agreement with the records; and state: (i) whether they have obtained all the information and explanations that they considered necessary; (ii) whether the requirements concerning disclosure of information about directors and officers’ remuneration, loans and other transactions have been met; and rectify any such omissions. The Companies Act places further duties on auditors relating to such issues as: (a) the valuation of non-cash consideration for share allotment by a public company or a company converting to a public company (ss.DD & A0H CA AIHE); (b) purchase or redemption of own shares by payment out of capital (s.AGC CA AIHE); (c) financial assistance for purchase of own shares (s.AEF CA AIHE). Potential liabilities In Caparo Industries plc v Dickman (AII0) company accounts were audited in accordance with the Companies Act AIHE. The respondents, who already owned shares in the company, decided to purchase more shares and take over the company after seeing the accounts. The accounts were inaccurate. The respondents then incurred a loss, which they blamed on the negligently audited accounts. It was held that, when the accounts were prepared, a duty of care was owed to members of the company (that is, the shareholders), but only so far as to allow them to exercise proper control over the company. This duty did not extend to members as individuals and potential purchasers of shares. The onus was clearly on the appellants in these circumstances to make their own indepedent inquiries, as it was unreasonable to rely on the auditors.
