Uncertainty
Estimates can depend on future outcomes, models, assumptions, and judgment.
Bias
Bias can appear through one-sided assumptions, selective data, or changes in methods.
Audit response
The auditor evaluates methods, assumptions, data, controls, and outcomes where relevant.
Exam strategy
Look for patterns across estimates, not only one number.
The takeaway
Auditors assess both reasonableness and patterns of management bias.
