Explanation

Under the CFA Institute Standards of Professional Conduct, Standard I(C) - Misrepresentation requires that members must not knowingly make any misrepresentations relating to investment analysis, recommendations, actions, or other professional activities.

Key points regarding attribution:

1. When issuing reports or research, members must properly attribute the work to the appropriate individuals or firms.
2. If a member who contributed to a report is no longer with the firm, proper attribution should still be provided to acknowledge their contribution.
3. Failure to provide proper attribution could constitute misrepresentation by implying that current firm members created work that was actually done by others.

Why the other options are incorrect:

• Option A: Disclosure of intended use of an external manager relates more to Standard V(A) - Diligence and Reasonable Basis or Standard III(A) - Loyalty, Prudence, and Care, not specifically to misrepresentation.
• Option B: While benchmarks are important for fair representation of performance, the requirement to "always" provide a benchmark is too absolute and not specifically mandated by the misrepresentation standard.

Correct Answer: C - provide attribution to a member who is no longer with the firm when issuing a report.
