Under what condition may Greg Stiles, CFA, withhold client information from CFA Institute?

In considering the obligations that Greg Stiles, CFA, has to uphold regarding client information, it is crucial to recognize that confidentiality is a fundamental ethical principle within the CFA Institute's Code of Ethics and Standards of Professional Conduct. CFA members are generally required to act with integrity and to disclose information to relevant entities when necessary, which includes the CFA Institute when they are seeking to uphold standards of conduct and professionalism.

Withholding client information from the CFA Institute is generally not permissible unless there are specific legal or regulatory obligations that allow for such withholding, which are not implied in the options provided. Therefore, no conditions in the listed choices justify the withholding of client information as it pertains to ethical governance and fiduciary responsibility.

In summary, the framework around confidentiality does not support withholding client information without strong justification, making the listed reasons insufficient. Thus, the correct conclusion aligns with the understanding that there are no acceptable conditions for withholding such information from the CFA Institute as proposed in the choices.
