1. Subsequent Events Evaluation (ISA 560 / IAS 10)
Transactions occurring between the balance sheet date and the date the audit report is signed must be reviewed by the auditor:
  • Adjusting Events: Provide extra evidence of conditions that existed at the balance sheet date (e.g., a customer goes bankrupt after year-end, confirming that an existing accounts receivable balance was uncollectible). Requires an explicit accounting entry to adjust the financial statements.
  • Non-Adjusting Events: Indicative of conditions that arose after the balance sheet date (e.g., a factory fire destroying inventory two weeks after year-end). Requires comprehensive footnote disclosure only; no balance sheet adjustments.
2. Evaluating Going Concern Viability (ISA 570)
The auditor must evaluate whether management’s use of the going concern assumption is appropriate. If the auditor identifies material uncertainties that cast significant doubt on the entity’s ability to continue operating (e.g., severe cash flow deficits, debt defaults, losing key export markets), they must ensure the financial statements transparently disclose these issues.
3. The Audit Report and Formulating Opinions
The audit report is the final deliverable. Opinions are divided into unmodified and modified variations:
  ┌───────────────────────────────── AUDIT OPINIONS ─────────────────────────────────┐
  │                                                                                  │
  │   ┌───────────────────────────── Unmodified Opinion ─────────────────────────┐   │
  │   │ Clean Report: Financial statements present fairly, in all material       │   │
  │   │ respects, in accordance with applicable framework (GAAP/IFRS).           │   │
  │   └──────────────────────────────────────────────────────────────────────────┘   │
  │                                                                                  │
  │   ┌────────────────────────────── Modified Opinions ─────────────────────────┐   │
  │   │                                                                          │   │
  │   │  • Qualified Opinion: Material misstatement/limitation exists, but it    │   │
  │   │    is NOT pervasive ("Except for... the statements present fairly").     │   │
  │   │                                                                          │   │
  │   │  • Adverse Opinion: Material misstatements are BOTH material and        │   │
  │   │    pervasive to the financial statements ("Do not present fairly").      │   │
  │   │                                                                          │   │
  │   │  • Disclaimer of Opinion: Auditor faces extreme scope limitations and    │   │
  │   │    CANNOT obtain evidence ("We do not express an opinion").             │   │
