The investment seeks total return. The fund pursues its objective by investing in a base portfolio that is generally comprised of an approximately equal mix of equity securities and money market instruments. It writes (sells) call options on the S&P 500® Index, a broad-based U.S. stock market index, and/or a substitute for the S&P 500® Index on substantially the full value of the fund's equity securities. The fund's equity investments consist of a diversified portfolio of common stocks that seeks to approximate the pretax total return performance of the S&P 500® Index.
