Business Continuity

IEX has developed a Business Continuity Plan (“BCP” or the “Plan”) detailing how the Firm will address the possibility of a future Significant Business Disruption (“SBD”) and respond to events of a varying scope which may impact the Firm’s business. Since the timing and impact of disasters and disruptions is unpredictable, the Firm will have to be flexible in responding to actual events as they occur. With that in mind, the Firm is providing you with this information regarding its Plan.
