Characteristics of Good Audit Evidence:

Sufficiency

Definition: Measure of the quantity of audit evidence.

Factors Affecting Sufficiency:

Risk Assessment: Higher risk requires more evidence
Materiality: More material items need more evidence
Quality of Evidence: Higher quality needs less quantity
Previous Experience: Past issues may require more evidence
Control Environment: Weak controls require more evidence

Appropriateness

Definition: Measure of the quality of audit evidence (relevance and reliability).

Components of Appropriateness:

Relevance: Evidence must relate to assertion being tested
Reliability: Depends on source, nature, and circumstances
Timeliness: Evidence should be current and relevant
Objectivity: More objective evidence is more reliable

Hierarchy of Evidence Reliability:

Auditor's Direct Knowledge: Evidence obtained directly through physical examination, observation, computation, or inspection
External Evidence: Evidence from independent external sources (bank confirmations, legal opinions)
