2.1 相关准则

相关准则

2.2 Requirements for audit evidence (ISA550)

  • Sufficient (Quantity)
  • Appropriate (Quality or Reliability)

2.3 Management assertion(管理层认定)

(ISA312.25) To provide a basis for designing and performing further audit procedures, the auditor shall identify and assess the risks of material misstatement at:

  • FS level
  • Assertion level for classes of transactions, account balances and disclosures

2.4 Audit procedures

2.4.1 Audit process

计划阶段:了解企业及其经营环境,识别和评估风险
执行阶段:设计和执行审计程序,获取充分恰当的审计证据
完成和复核阶段:得出审计意见,复核审计工作,形成审计报告

审计工作流程

2.4.2 Types of Audit procedures

  • Inspection of assets
  • Inspection of documentation
  • Observation
  • Enquiries
  • Confirmation
  • Recalculations
  • Reperformance
  • Analytical procedures

使用哪些审计程序是审计人员的一项职业判断(judgement),通常依据的是对control risk的评估。内控好,风险低,通过控制测试证明内控有效,此时可用分析性程序和询问;相反,多用实质性程序和其他方法。

2.5 Audit Sampling (ISA530)

  • Sampling risk - 检查总体和样本所得出的结论不一致,该风险随着样本量增大而下降
  • Non-sampling risk - 与样本容量无关的因素导致得出错误结论的风险

2.6 Written representations 管理层声明书 (ISA580)

The auditor may require confirmations from directors that have provided information as required by laws and regulations as well as the agreed terms of the audit engagement. (声明提供的信息符合法律法规和审计约定书中的要求)

  • 何时需要

    • When facts are confined to management - 证据只能从管理层得来
    • When it it s a matter of opinion or judgement - 信息涉及管理层的意见或判断
  • 如果管理层拒绝提供声明书,而审计人员觉得是必要的
    insufficient / inappropriate audit evidence,属于审计范围受限,出具保留except for或无法表示意见disclaimer of opinion。

  • 如果是contradictory evidence
    调查情况并重新考虑管理层声明书的可靠性。

  • 如果提供的管理层声明书不足以构成充分恰当的审计证据

    • 审计师应当通过企业内部外部渠道,获取相佐证的corroborative审计证据
    • 评估是否WR合理,并与其他审计证据相一致
    • 考虑提供管理层声明书的人是否了解相关的事项所涉及到的信息

管理层声明书虽然是一个审计证据,但其有效性不高,特别是涉嫌舞弊时。所以有时会从治理层governance获取声明书。

2.7 Audit documentation (ISA230.8)

2.7.1 Requirements of audit documentation

The auditor shall prepare audit documentation that is sufficient to enable an experienced auditor, having no previous connection with the audit, to understand:

  • Nature, timing and extent of audit procedures to comply with ISAs

    专家工作相关性和合理性的考虑因素
  • 如果not adequate (ISA620.13)


    审计师在专家工作不恰当时的操作

2.8.4 利用专家工作后 (ISA620.14)

  • Read the relevant internal audit reports to understand the nature and extent of audit procedures performed and the findings
  • Carry out and document 'sufficient audit procedures' on the internal audit work to be used to assess its adequacy for the purposes of the audit

2.10 Related parties (ISA550)

Parties that are considered to be related if one party has the ability to control the other party or exercise significant influence over the other party in making financial and operating decisions.

IAS24 Related Party Disclosure requires entities to disclose:

  • Related party relationships where control exists
  • Transactions with these and other related parties

  • Management responsibility
    identify and disclose related party relationships and transactions
