The Sub-Adviser does not anticipate utilizing customary economic, financial or market analyses or other traditional investment techniques to manage the Portfolio. The Portfolio is constructed and maintained by utilizing a replication construction technique. That is, the Portfolio seeks to hold all securities in the Russell 1000 Growth in the exact weight each security represents in the Index.
