Safeguards against threats to independence
For gifts/hospitality: Document on audit file even if refused
For owning shares: Any member of the audit team or immediate family must sell shares or be removed from the team
For overdue fees: Do not perform further work until arrangements have been made for payment
For business relationships: Unless immaterial no safeguard can reduce the threat so can't be done
For potential employment with an audit client: Firm must be notified and the individual removed from the audit. Perform a review of any significant judgements made by the individual
