Core professional ethical principles (VSA 200)
According to VSA 200, the principle audit of financial statements This stems from stringent ethical standards. Without integrity and independence, any audit opinion becomes worthless to the users of the report.
The Principle of Independence
Independence is the "soul" of the auditing profession. The principles of auditing financial statements require auditors to be independent both in thought and form, having no economic or family relationship with the audited entity.
For example, an auditor who owns shares in Company A is not allowed to participate in the audit of that same company. This restriction aims to ensure that the opinion given is not distorted by personal interests.
Integrity and Objectivity
Integrity demands honesty and truthfulness. Objectivity means not allowing prejudice, conflicts of interest, or third-party influence to influence professional judgment.
The principles of financial statement auditing clearly state that auditors must report errors truthfully, regardless of pressure from the entity's management.
Professional Competence and Due Care
The principles of auditing financial statements require auditors to maintain the necessary professional knowledge. Prudence demands that they work diligently and carefully, in accordance with applicable technical standards.
Auditors need to participate in continuing education programs (CPD) to understand the latest tax and accounting regulations, thereby enabling them to make accurate assessments.
Information security (Confidentiality)
Confidentiality is a crucial principle in financial statement auditing aimed at protecting clients. Auditors must not disclose information to third parties unless they have consent or are legally obligated to do so.
The risk-based and materiality-based implementation principles (VSA 315 & 320)
In practice, auditors cannot examine 100% transactions. Therefore, modern financial statement auditing principles focus on high-risk areas and material items.
Determine the level of materiality.
Materiality refers to information whose absence or inaccuracy could alter the decisions of those using the report. The principles of financial statement auditing require establishing "thresholds" to focus resources accordingly.
Materiality levels are typically calculated as a percentage of Revenue, Profit, or Total Assets. Deviations below this level may be disregarded if they are not substantial.
Assessing the risk of material misstatement
The risk-based principles of financial statement auditing help in effective planning. Auditors need to assess the inherent risks and control risks of the business.
For example, a business with a large inventory of perishable goods would be identified as a high-risk area. Auditors would need to witness more thorough inventory checks in these locations.
The principle of gathering sufficient and appropriate audit evidence (VSA 500)
All auditors' opinions must be based on factual evidence. The principles of financial statement auditing stipulate that evidence must be "sufficient" in quantity and "appropriate" in quality.

- Physical inspection: Inspect the fixed assets or inventory in person.
- Send confirmation email: Contact the bank or customer to confirm the balance.
- Recalculate: Verify the mathematical accuracy of accounting tables and charts.
- Interview: Discuss internal control procedures with staff.
Reliability of evidence
The principles of financial statement auditing emphasize that evidence from third parties is generally more reliable. Written evidence is also considered more trustworthy than purely oral evidence.

- Regulations not updated: For example, the latest changes regarding provisions for doubtful receivables under the current circular do not apply.
