An unsatisfactory operational due diligence (ODD) review can cause an investor to pass on an investment opportunity, regardless of the success of the manager’s investment team, cautioned the speakers at a recent Eze Castle Integration (ECI) seminar. The program examined the growing importance of ODD; ways advisers can prepare for ODD; certain ODD red flags; third-party management; and information technology and cybersecurity concerns. Olivia Munro, senior marketing specialist at ECI, moderated the discussion, which featured Mary Beth Hamilton, vice president of ECI, and Frank L. Napolitani, managing director at consulting firm Constellation Advisers, LLC. This article summarizes the key takeaways from the program. See “Perspectives on Operational Due Diligence From an Investor, Consultant and Manager” (Nov. 9, 2017).
