Scenario: A firm uses a vendor's research in a client report but fails to disclose the vendor’s compensation relationship. Which CFA Institute Standard is violated?

• A. Standard IV.C Suitability
• B. Standard IV.E Preservation of Confidentiality
• C. Standard V.A Diligence and Reasonable Basis
• D. Standard VI.A Disclosure of Conflicts

Answer: (D)

Conflicts of interest must be disclosed in client communications to preserve transparency and objectivity. When a firm uses a vendor’s research in a client report but does not reveal the vendor’s compensation relationship, the client cannot assess whether the research or recommendations were influenced by that relationship. This lack of disclosure creates a material potential for bias and misleads the client about the independence of the analysis. The CFA Institute standard on Disclosure of Conflicts requires these disclosures so clients can judge credibility and objectivity. So, the scenario violates that standard.

The other standards focus on different requirements—suitability deals with recommending appropriate investments, confidentiality with protecting client information, and diligence and reasonable basis with ensuring the analysis has a solid foundation. They don’t specifically address the need to disclose financial relationships that could influence research or recommendations, which is why this scenario aligns with the disclosure-of-conflicts standard rather than those others.
