Over the last few years, the subject of ethics and compliance in organizations of various kinds and sizes has greatly increased in visibility and importance for practitioners of governance, their advisors and mentors, for monitors of ethics and compliance processes, and for those responsible for oversight. The parade of business scandals and ethical lapses that has seemed to continue without significant letup has led to continued legislative and regulatory mandates for improved governance practices. Practitioners of internal auditing, as significant components of governance processes, and also persons in related fields, need to be particularly aware of all developments affecting organizational ethics and compliance. Members of audit committees, corporate counsel, and external auditors should also be knowledgeable about matters concerning ethics and compliance, as their responsibilities in ethics and compliance are also increasing. An objective of Ethics and Compliance: Challenges for Internal Auditing is to help fulfill those needs.
