Final answer:
FINRA retains jurisdiction over a person who leaves the securities business for two years. During this period, they can be disciplined for actions taken while they were associated with a FINRA member firm.
Step-by-step explanation:
When a registered person leaves the securities business, the Financial Industry Regulatory Authority (FINRA) retains jurisdiction over that person for two years. This means that for two years following their departure, the individual can still be held accountable by FINRA for their actions while they were associated with a FINRA member firm. It's important to note that this timeframe pertains to FINRA's ability to initiate a disciplinary proceeding if the need arises.
