How should the audit committee see issues handled through interim management letters?

The audit committee does not need every low-risk housekeeping item. It does need visibility into significant matters, unresolved issues, repeated themes, accepted risk, and items that could affect governance oversight. If interim letters were used during the engagement, the final communication can summarize significant issues and note whether management has completed, started, or committed to corrective action.

This is especially important when the final report is the committee's main view of the engagement. A clean final report should not create the false impression that no significant issues were identified.
