The Portfolio seeks to achieve its objective by investing in a portfolio of real estate investment trusts (“REITs”). Invesco Capital Markets, Inc. is the Sponsor of the Portfolio. The Portfolio is diversified among different publicly-traded REIT sectors, including but not limited to: office, apartment, industrial, retail, self-storage and healthcare. Further, the strategy and philosophy are based on two fundamental principles: maximizing predictability and consistency of investment returns, and minimizing risk through strict attention to portfolio design. The first step in the selection process is defining a qualified universe of equity REITs, including only companies with sufficient trading volume to provide liquidity. The second step is fundamental analysis of properties, market cycles, management teams and corporate structures, evaluating the properties on the basis of location and physical attributes, and eliminating weaker or higher-risk companies. Step three is securities analysis, in which stocks are evaluated and rated according to relative value using multiple valuation criteria. Portfolio construction is the final step, including statistically measuring, setting and monitoring risk and return, diversifying among all major industries of real estate, seeking the potential for optimum risk/return for the overall portfolio.As of the Initial Date of Deposit, the Portfolio invests at least 80% of its assets in publicly traded REITs that own, develop, acquire or operate income-producing real estate properties.
