The engagement supervisor prepares the final engagement communication for dissemination.

The CAE is ultimately accountable for all final engagement communications, even if dissemination is delegated to others. The Standards hold the CAE responsible for ensuring that reports are accurate, objective, clear, concise, constructive, complete, and timely.

Options A and D (supervisor or team) may assist but do not hold accountability. Option C (the board) receives reports but is not responsible for them.
