INVESTMENTS IN EACH FUND

Name of Portfolio Manager	Fund Name	Dollar Range of Investments in Each Fund (as of January 31, 2014)
Bailard, Inc.
Warren Matthew Johnson	Nationwide Bailard Technology & Science Fund	None

DESCRIPTION OF COMPENSATION STRUCTURE

Bailard, Inc. (“Bailard”)

Mr. Johnson and Mr. Smith are each paid a base salary, an “investment performance” bonus relating to the Fund each manages and, potentially, an additional discretionary bonus. The investment performance bonus is designed to be significant but not so significant that it would encourage extreme risk taking. It is based on the relevant Fund’s return ranking relative to a dynamic subset of that Fund’s peer group: Morningstar Specialty Technology (for Nationwide Bailard Technology and Science Fund). The discretionary bonus, if any, reflects the pre-tax profitability of Bailard and the portfolio manager’s contribution to meeting Bailard’s general corporate goals.
