as administratively feasible following the launch of future Fidelity Freedom Funds®, unless otherwise directed

investment options as they are launched, such funds being available to Plan participants as of the open of trading on the New York Stock Exchange on their respective inception dates or as soon thereafter as administratively possible, unless
otherwise directed by the PIC.
