Final answer:
HR should recommend that this unethical practice stop and discuss alternative incentive plans.

HR should recommend that this unethical practice stop and discuss alternative incentive plans. Incentivizing brokers to generate sales based on the firm's ownership in a particular fund creates a conflict of interest and can lead to unethical behavior. Instead, HR should explore other ways to motivate and reward brokers that align with ethical standards and promote long-term success for the firm.
