Aggregate errors are added together to determine whether, in aggregate, misstatements are material.

Aggregate errors are added together to determine whether, in aggregate, misstatements are material.

• A. To adjust planning materiality only
• B. To determine whether, in aggregate, misstatements are material
• C. To identify single largest error
• D. To calculate detection risk

Answer: (B)

Materiality is judged for the financial statements as a whole, so auditors sum up all identified misstatements and estimates of misstatements to see their overall effect. If the total of uncorrected misstatements is material in aggregate, adjustments are needed or the impact is considered when forming the opinion. Individual misstatements may be immaterial on their own but become material when added together. This is the reasoning behind using aggregate misstatements to assess materiality, rather than focusing on a single largest error or on detection risk. Planning materiality is a threshold used to design procedures, not the sole basis for deciding whether the aggregate of misstatements is material.
