Under normal conditions, through the underlying funds, the Fund indirectly invests in the equity securities of U.S. and foreign micro-cap, small, and mid-sized companies. The Fund uses a blend strategy to gain investment exposure to both growth and value stocks, or to stocks with characteristics of both. Equity securities in which an underlying fund may invest include common stocks, preferred stocks, equity interests in trusts (including real estate investment trusts and privately offered trusts), partnerships, joint ventures, limited liability companies and vehicles with similar legal structures, and other instruments with similar economic characteristics. Securities of foreign companies include emerging market companies, American Depositary Receipts (ADRs), and other similar depositary receipts. In addition to ADRs, the Fund generally defines foreign companies as those whose securities are traded primarily on non-U.S. securities exchanges. In addition to investing in the underlying funds, the Fund may invest directly in any type of derivative as part of its investment strategies or for risk management purposes. Currently, the Fund may invest in derivatives consisting principally of futures, forwards, options, and swaps. To the extent that the Fund invests directly in derivatives, the Fund intends to do so primarily for non-hedging purposes. The market value of the Funds directly held positions in derivatives, determined at the time of the most recent position established, will not exceed 50% of the Funds net assets. The Fund currently expects, however, that the market value of such instruments, determined at the time of the most recent position established, will not exceed 35% of the Funds net assets under normal conditions. These percentage limitations exclude Fund assets indirectly invested in derivatives through the underlying funds. The Funds portfolio management team generally employs a bottom-up investment approach emphasizing long-term value. The Fund may sell or reallocate its investments among the underlying funds for a variety of reasons, such as to secure gains, limit losses, redeploy assets, increase cash, or satisfy redemption requests, among others. The Fund may deviate from the investment strategy described above for temporary defensive purposes. The Fund may miss certain investment opportunities if defensive strategies are used and thus may not achieve its investment objective. Show less
