The partner is Cathy. She has been involved in the ABC audit for over 20 years and partner on the engagement for the last 15 years. The chairman of the board has asked whether Cathy can be appointed as a non-executive director. The board lacks a financial reporting expert, and the appointment of an audit partner would bring much needed knowledge and experience. Cathy has agreed to attend meetings from time to time and provide financial reporting guidance and advice to the board.

The graduate is John. While a student, John worked part-time in the accounting department at ABC undertaking basic processing tasks. Johns friend is the receptionist at ABC. The receptionist has no accounting knowledge and has no involvement with the recording or processing of accounting transactions

As such, the threats created in the above two cases are self-interest, self-review and Familiarity

My question is, what action can the audit partner take to remove threats?
