Strategy. The Funds investment objective is pursued through a real estate value strategy (as described in more detail below) through investment in international public real estate securities, which may include equity real estate investment trusts (a REIT or REITs), mortgage REITs, REIT preferred securities, and other publicly traded companies whose primary business is in the real estate industry. This strategy may lead to investment in smaller capitalization companies (under $1 billion). The composition of the portfolio does not seek to mimic equity REIT indices.

This strategy may lead to investment in smaller capitalization companies (under $1 billion). The composition of the portfolio does not seek to mimic equity REIT indices. Under normal conditions, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of companies principally engaged in the real estate industry outside of the United States. Equity securities can consist of shares of REITs and securities issued by other companies principally engaged in the real estate industry. Equity securities can also include securities convertible into common stocks where the conversion feature represents, in the Advisers view, a significant element of a securitys value, and preferred stocks. The Fund considers a company to be principally engaged in the real estate industry if it either (i) derives at least 50% of its revenues from the ownership, construction, financing, management or sale of commercial or residential real estate or (ii) has at least 50% of its assets in real estate or such real estate businesses. These include securities issued by REITs or comparable foreign structures, and real estate operating companies. REITs and comparable foreign structures are pooled investment vehicles which invest primarily in income producing real estate or real estate related loans or interests and which may have corporate tax advantages relative to other corporate structures. The Fund may invest in equity REITs and mortgage REITs. Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling property that has appreciated in value. Mortgage REITs generate revenue from interest earned on mortgage loans. The Fund does not invest in real estate directly. The majority of the Funds assets will normally be invested in the securities of companies located in countries other than the United States, although these companies may have investments that provide exposure to the U.S. real estate industry. The Fund may invest in securities of issuers located in emerging market countries, but does not expect to invest greater than 30% of assets in such securities. For purposes of the foregoing, the Fund considers an issuer to be located in a particular country based on where the issuer is domiciled, where it maintains its headquarters (or primary base of operations) or where its securities are registered and/or traded. The real estate value strategy seeks to invest in companies that in the Advisers view have underlying real estate assets that are trading at a discount to the private market value of such assets, have the ability to grow the value of real estate asset above average, or have an above-average free cash flow yield. The Adviser screens its universe of real estate securities for a number of proprietary valuation, income, and balance sheet metrics to identify candidates for investment. This process is combined with in-depth industry and company-specific research to narrow the investment options for the Fund. The Fund may invest in companies without regard to their market capitalization. The Funds strategy is an all-cap strategy which means that investments are made without regard to a companys market capitalization. The Funds investment process is indifferent to index weightings which generally results in a portfolio that is differentiated by company names and percentage exposures. The portfolio of securities in which the Fund invests will normally represent a broad range of geographic regions, property types and tenants. The Funds investment strategy also considers the impact that real estate companies have on the environment and other sustainability considerations when making investment decisions for the Funds investment portfolio. In assessing sustainability, the Adviser considers different factors, including environmental, social, and governance (ESG) criteria. Some of the environmental criteria the Adviser considers include energy consumption and efficiency, water use, carbon emissions, recycling and waste reduction, and level of green building certifications among others. Some of the social criteria the Adviser considers include the level of community engagement, customer/tenant well-being, employee health and safety, employee diversity and equality, employee training and responsible supply chain, among others. Some of the governance criteria that the Adviser considers include reporting and disclosure, business ethics, management alignment through ownership and remuneration, governance structure, board transparency and cybersecurity, among others. The Adviser performs its own internal research as it relates to measuring an investments ESG criteria. The items discussed above are illustrative and do not necessarily reflect the full range of ESG criteria that may be applied in analyzing a particular security for investment. The availability of information about a company, issues associated with a particular industry, changing social conditions or other circumstances may affect the manner in which the ESG criteria are applied in a particular situation. Companies in which the Fund may invest do not necessarily meet the highest standards in all aspects of ESG performance. We do believe that a well-managed company is one that considers ESG criteria when operating their business. These companies look for opportunities to improve relations with employees, consumers, communities and the environment. In addition, these companies tend to work towards improving in these areas, and, in our opinion, these efforts over the long-term will serve investors well. The Fund is non-diversified, which means that the Fund may invest its assets in securities of fewer issuers than would a diversified mutual fund. Show less
