Audit Engagements Explained: Process, Responsibilities, and Key Objectives
Overview: An audit engagement is more than just issuing an opinion — it’s a structured process with specific responsibilities for both management and the auditor. Here’s how it works, step by step.
✅ General Audit Process
- Engagement Acceptance: Confirm ethics, independence, and clear terms of engagement.
- Risk Assessment & Planning: Develop an audit strategy, determine materiality, understand the entity and its environment, internal controls, and assess risks.
- Perform Procedures & Obtain Evidence: Perform tests of controls and substantive testing to gather sufficient appropriate evidence.
- Form Conclusions: Evaluate results, assess subsequent events, get management representations, and perform final quality control.
- Reporting: Issue the audit report with the appropriate opinion and any other required communications.
✅ The Independent Audit Function
The purpose of an audit is to give users confidence that the financial statements are presented fairly, in all material respects, in line with the applicable financial reporting framework (e.g., U.S. GAAP, IFRS, or special purpose frameworks). The auditor’s report provides this credibility because it comes from an objective, independent party.
✅ Management’s Responsibilities
Management is responsible for:
- Preparing and fairly presenting the financial statements.
- Designing, implementing, and maintaining internal controls to prevent or detect material misstatement.
- Providing the auditor with all necessary information and access.
✅ Auditor’s Responsibilities
The auditor’s job is to express an opinion based on sufficient appropriate audit evidence, while:
- Maintaining professional skepticism and judgment.
- Complying with relevant ethical requirements, including independence.
- Following all applicable GAAS (or additional frameworks like PCAOB, ISAs, or GAGAS if required).
📌 Professional Skepticism
Auditors must not automatically assume management is honest nor dishonest — they must be alert for inconsistencies, possible fraud, or contradictory evidence. This attitude underpins all audit judgments.
✅ Reasonable Assurance & Inherent Limitations
Reasonable assurance is a high level of assurance but not absolute. Why? Because:
- Financial reporting involves judgment and estimates.
- Fraud can be hidden intentionally.
- Auditors rely on sampling and testing within a reasonable timeframe.
✅ Types of Engagements
- Nonissuers: Can opt for a financial statement audit or an integrated audit that includes internal controls.
- Issuers: Must have an integrated audit of both the financial statements and internal controls over financial reporting.
- ERISA Plans: Include special reporting for certified investment information and plan governance, if applicable.
✅ Overall Objectives
- Financial Statement Audit: Obtain reasonable assurance that the statements are free from material misstatement, and issue an opinion.
- Internal Control Audit: Express an opinion on the effectiveness of internal control over financial reporting.
- ERISA Plan Audit: Evaluate plan financial statements, supplementary info, and reportable findings.
