Answer: Under FINRA rules, this is an example of non-cash compensation and is prohibited.
FINRA forbids enrolled individuals from accepting a acquisition in the sum of more than $100, and also forbids representatives from accepting "non-cash compensation".
The mutual fund sponsor is not the employer of the registered representative - the representative is an employee of the broker-dealer who is in the mutual fund selling group. The benefactor is not permitted to hold such contest - only the employing organizations can hold such contest, provided that it cannot favor the sale of one fund over another. This is an example of "non-cash compensation" under FINRA rules and is prohibited.
