Under what condition can Members and Candidates accept additional compensation from third parties?

The correct answer is that Members and Candidates can accept additional compensation from third parties only with written consent from all relevant parties. This condition is crucial to maintain transparency and uphold ethical standards in the finance and investment industry.

Written consent ensures that all parties involved are aware of the compensation arrangement and agree to it, thereby minimizing potential conflicts of interest. This requirement serves to protect not just the Member or Candidate but also their employer and clients. It reinforces the importance of maintaining trust and integrity in professional relationships, which is essential in alternative investments and finance sectors.

The other options don't align with the ethical guidelines set forth for Members and Candidates. While the idea of mutual benefit or competitive salary might seem appealing, they do not adequately address the necessity of disclosure and consent in compensation arrangements. Therefore, the emphasis on obtaining written consent establishes a clear framework for ethical conduct within the industry.
