Lecture on Auditor's Reliance on Third Parties

Introduction

  • Auditors often need to rely on third parties for evidence.
  • This includes experts like:
    • Valuers for property portfolios.
    • Actuaries for pension liabilities.
    • Lawyers for lawsuit outcomes.
  • Internal auditors can perform audit tasks to assist external auditors.

Role of External Experts

  • Valuers: Provide market prices for land and buildings.
  • Actuaries: Evaluate pension fund adequacy.
  • Lawyers: Offer opinions on legal case outcomes.
  • Internal Auditors: Evaluate internal controls and assist with procedural work.
  • Other External Auditors: In group audits, reliance may be placed on subsidiary auditors.

Criteria for Selecting Third Parties

  • Must be professionally qualified.
  • Appropriately experienced in the relevant sector.
  • Maintain independence to avoid biased outcomes.
  • Belong to professional firms with good reputations.

Agreement with Third Parties

  • Define the exact scope of work.
  • Set deadlines and ensure clarity in communication.
  • Ensure confidentiality of sensitive information.

Auditor Responsibility

  • Auditors cannot fully delegate responsibility; they must scrutinize expert opinions.
  • Check consistency with other evidence and assumptions.
  • Validate the accuracy of source data.

Internal Audit

  • Enhances company’s internal control under corporate governance.
  • Ideally, report to the Audit Committee, not to executives like the Finance Director.
  • Helps in:
    • Assessing risk and managing it.
    • Designing and checking internal control systems.
    • Conducting procedural audits and special investigations.
    • Performing value-for-money audits.
    • Testing IT controls.
  • Essential collaboration with external auditors.

Collaboration Between Internal and External Auditors

  • Internal auditors should maintain high standards in their work.
  • External auditors must review internal auditors' work for quality assurance.

This lecture emphasized the importance of third-party reliance in auditing, the criteria for choosing these parties, and the crucial role of internal auditors in supporting external auditors while maintaining quality and responsibility in their own work.
