Answer: report the issue to his supervisor.

## Explanation According to the CFA Institute Standards of Professional Conduct, specifically Standard I(A) - Knowledge of the Law and Standard V(A) - Diligence and Reasonable Basis, Lagarde should: 1. **Report to his supervisor first** (Option A) - This is the most appropriate initial step. When an analyst discovers potential material misrepresentations or omissions in financial information, they should first bring this to the attention of their supervisor or compliance department. 2. **Why not Option B (issue report showing losses)**: Lagarde cannot independently issue a report with unverified information. He only has suspicions based on inconsistencies, not confirmed facts. Issuing a report with unsubstantiated claims could violate Standard V(A) which requires a reasonable basis for investment analysis. 3. **Why not Option C (use prospectus data)**: While the prospectus has been approved by regulators, if Lagarde has reasonable doubts about its accuracy, he cannot simply ignore his concerns. However, he cannot independently change the data without proper verification and authorization. 4. **Additional considerations**: - Lagarde should document his concerns and the evidence - He should follow his firm's internal compliance procedures - If the supervisor doesn't take appropriate action, he may need to escalate to the compliance department - He should consider whether to include a disclosure in his report about the potential issues 5. **Ethical obligations**: As a CFA charterholder, Lagarde has a duty to maintain the integrity of the capital markets and ensure that investment recommendations have a reasonable basis. Reporting his concerns internally is the first step in fulfilling these obligations while allowing the firm to investigate properly.
