It’s listed under recommended items to not accept cash gifts, as part of the asset manager code. And it says :
“Managers must adopt additional, detailed poli- cies and procedures to effectively implement the Code.”
the specific piece mentioning cash:
“Managers should establish a written policy limiting the acceptance of gifts and entertainment to items of minimal value. Managers should consider creating limits (e.g., amount per time period, per vendor) for accepting gifts and prohibit the acceptance of any cash gifts.”
(Level III Volume 1 Ethical and Professional Standards , 4th Edition. Pearson Learning Solutions p. 271).
But I’m not sure if that is different than the example above of a gift from a client.
