Under normal circumstances, the Portfolio invests at least 80% of its net assets (plus any borrowings for investment purposes) in companies that are primarily engaged in the real estate industry. This includes companies such as real estate investment trusts (REITs) and other real estate related investments. A real estate company generally derives at least 50% of its revenue from real estate ownership, leasing, management, development, financing or sale of residential, commercial or industrial real estateor has at least 50% of its assets in real estate. Should the Adviser determine that the Portfolio would benefit from reducing the percentage of assets invested in companies that are primarily engaged in the real estate industry from 80% to a lesser amount, it will notify you at least 60 days prior to such a change. This Portfolio may invest up to 20% of its assets in equity and fixed income securities of companies which are not principally engaged in the real estate industry or which are not income producing equity securities of companies principally engaged in the U.S. real estate industry. In buying and selling securities for the Portfolio, the Adviser uses an active strategy. This strategy consists of a disciplined approach that involves computer-aided, quantitative analysis of fundamental, technical and risk-related factors. The Advisers factor model (a method of analyzing and combining multiple data sources) systematically reviews potential investments, using data such as historical earnings growth and expected future growth, valuation, price momentum, and other quantitative factors to forecast return potential and determine the Portfolios holdings.
