The document discusses the challenges facing investment committees in navigating volatile market conditions. It describes three oversight models - committee-centric, staff-centric, and advisor-centric - that vary in their reliance on the committee, staff, or external advisors.

Outsourcing some functions to advisors may help, but committees still retain fiduciary duties and must find the right balance of involvement. Selecting the appropriate oversight model is crucial given complex modern portfolios.
