You are a staff person and overhear the audit senior and manager discussing an immaterial fraud that was discovered by the client. The client does not wish to disclose it to the audit partner or the audit committee. They have concluded that because it is a small amount, they agree with the client that they will not tell the partner nor include it in the audit committee report. You seem to recall from training that all frauds should be reported to the audit committee. What options do you have as a member of the team?
