The investment seeks investment results that correspond generally to the price and yield (before the fund's fees and expenses) of an equity index called the Capital Strength Index(SM). The fund will normally invest at least 90% of its net assets (including investment borrowings) in the common stocks and real estate investment trusts (REITs) that comprise the index. The index seeks to provide exposure to well-capitalized companies with strong market positions that have the potential to provide their stockholders with a greater degree of stability and performance over time.
