The foundation of every audit. Sets out the auditor's overarching responsibilities and defines the nature, scope and structure of an audit.
| Objective (a) | Objective (b) |
|---|---|
| Obtain reasonable assurance that the FS as a whole are free from material misstatement (fraud or error) — enabling expression of an opinion. | Report on the FS and communicate as required by the ISAs, in accordance with the auditor's findings. |
→ Auditor must disclaim an opinion or withdraw from the engagement (where withdrawal is permitted by applicable law or regulation).
| Term | Definition |
|---|---|
| Audit Risk | Risk of expressing an inappropriate opinion when FS are materially misstated. = f(RMM × Detection Risk) |
| Detection Risk (DR) | Risk that procedures will NOT detect a material misstatement. Inversely related to RMM. |
| Inherent Risk (IR) | Susceptibility of an assertion to misstatement, before considering controls. |
| Control Risk (CR) | Risk that a misstatement will NOT be prevented or detected by the entity's controls. |
| Reasonable Assurance | High but NOT absolute level of assurance. |
| Professional Skepticism | Questioning mind; alertness to misstatement conditions; critical assessment of audit evidence. |
| Professional Judgment | Application of relevant training, knowledge and experience to make informed audit decisions. |
| Audit Evidence | Information used to reach conclusions. Sufficiency (quantity) and Appropriateness (quality = relevance + reliability). |
| Misstatement | Difference between reported and required amount/classification/disclosure. Arises from error or fraud. |
| Component | Controlled By | Key Point |
|---|---|---|
| Inherent Risk (IR) | Entity | Higher estimation uncertainty → higher IR. Exists independently of the audit. |
| Control Risk (CR) | Entity | Controls can reduce but NEVER eliminate risk. Some CR always exists. |
| Detection Risk (DR) | Auditor | Inversely related to RMM. Managed through audit procedures. |
| Source | Examples |
|---|---|
| Nature of Financial Reporting | Management judgment; subjective decisions; range of acceptable interpretations |
| Nature of Audit Procedures | Incomplete information; fraud via collusion; auditor cannot authenticate documents; no legal investigative powers |
| Time & Cost Constraints | Must complete within reasonable period; cannot pursue every matter exhaustively |
| Requirement | Detail |
|---|---|
| Comply with all relevant ISAs Para. 18 | Relevant when ISA is in effect AND the circumstances it addresses exist. |
| Understand entire ISA text Para. 19 | Including application and other explanatory material. |
| No false compliance claim Para. 20 | Cannot claim ISA compliance unless actually complied with all relevant ISAs. |
| Failure to achieve objective Para. 24 | Evaluate impact → may need to modify opinion or withdraw. Must document. |
| Purpose of audit | Enhance user confidence — NOT guarantee FS correctness |
| Reasonable assurance | High but NOT absolute — inherent limitations always exist |
| Audit risk formula | AR = RMM × DR; RMM = IR × CR |
| Detection Risk | Only component the auditor directly controls — inverse to RMM |
| Professional skepticism | Mandatory throughout; management's honesty does not reduce it |
| Audit evidence | Persuasive not conclusive; sufficiency AND appropriateness both matter |
| Cannot achieve objective | Disclaim opinion or withdraw from engagement |
