As a portfolio manager, you have recently been offered a position on the board of a local charity organization. The charity is known for its impactful work, but it has also faced scrutiny for its investment ethics, specifically regarding some of its portfolio holdings in controversial industries such as tobacco and weapons manufacturing. You must decide whether or not to accept the board position.
In this context, you are aware that your role on the board may enhance your reputation and networking opportunities. However, you also have a responsibility to uphold the CFA Institute's Code of Ethics and Standards of Professional Conduct, which emphasize the importance of acting with integrity and maintaining the trust of clients and the investment community.
What is the most appropriate course of action considering both your professional obligations and the potential conflicts of interest?
