The Portfolio invests primarily in equity securities, principally common stocks, of infrastructure companies.  As a result, the Portfolio concentrates its investments in industries represented by infrastructure companies. The Investment Manager generally focuses on companies with a minimum market capitalization of at least $2 billion. Although the Portfolio generally focuses on large capitalization companies, the market capitalizations of issuers in which the Portfolio invests may vary with market conditions.

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities of Infrastructure Companies. Infrastructure Companies derive at least 50% of their revenues from, or have at least 50% of their assets committed to, the generation, production, transmission, sale or distribution of energy or natural resources used to produce energy; distribution, purification and treatment of water; provision of communications services and media;

management, ownership and/or operation of infrastructure assets or construction, development or financing of infrastructure assets, such as pipelines, toll roads, airports, railroads or ports. Emerging market countries include all countries represented by the MSCI Emerging Markets Index, which as of June 30, 2025 includes: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Kuwait, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and United Arab Emirates.

Under normal market conditions, the Portfolio invests significantly (at least 40%—unless market conditions are not deemed favorable by the Investment Manager, in which case the Portfolio would invest at least 30%) in infrastructure companies organized or located outside the U.S. or doing a substantial amount of business outside the U.S. The Investment Manager allocates the Portfolio’s assets among various regions and countries, including the United States (but in no less than three different countries). The Portfolio may invest in equity securities of companies with some business activities located in emerging market countries.

The Investment Manager generally seeks to substantially hedge foreign currency exposure in the Portfolio against movements relative to the U.S. dollar by entering into foreign currency forward contracts, although the Portfolio’s total foreign currency exposure may not be fully hedged at all times.

As part of its investment strategy, the Portfolio may use repurchase agreements or money market mutual funds to maximize the value of its assets held in cash. Under a repurchase agreement, the seller agrees to repurchase a security (typically a security issued or guaranteed by the U.S. Government) at a mutually agreed upon time and price. This is intended to insulate the Portfolio from changes in the market value of the security during the period.

Although the Portfolio is classified as “diversified” under the Investment Company Act of 1940, as amended, it may invest in a smaller number of issuers than other, more diversified investment portfolios.

The Investment Manager seeks to achieve the investment objective through investing in an actively managed, diversified, long-only portfolio comprised primarily of equity securities, principally common stocks, of small capitalization U.S. companies. The Investment Manager considers “small cap companies” to be those companies that, at the time of initial purchase by the Portfolio, have market capitalizations within the range of companies included in the Russell 2000 Index (ranging from approximately $54.5 million to $15.9 billion as of June 30, 2025). The Portfolio typically invests in 200 to 500 companies.

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities of small cap U.S. companies. Equity securities also may include depositary receipts, including American Depositary Receipts (“ADRs”), Global Depositary Receipts and European Depositary Receipts. The Portfolio may invest up to 20% of its assets in other securities which need not be equity securities of small cap U.S. companies, including investments in larger U.S. companies and in non-U.S. companies.

The Investment Manager actively manages the Portfolio using its proprietary investment strategy that creates and applies fundamental and quantitative techniques into a fully systematic process, which is designed to convert subjective criteria into various quantitative formulas to make investment decisions based upon fundamental market data. The Investment Manager terms this its “Automated Fundamental Analyst” investment framework, which involves steps including the following:

· identification of a fundamental opportunity, a recurring market inefficiency where the Investment Manager believes that investors are not fully incorporating the impact of a company’s changing operating fundamentals and/or attractive valuations;

· converting this market observation into quantified conditions utilizing proprietary process, knowledge and techniques;

· attempting to validate the observation through extensive proprietary testing that includes historical data, minimum targeted return objectives and persistence hurdles;

· through the operation of each Automated Fundamental Analyst, a number of securities are identified; and

· the securities selection process is implemented systematically into automated daily operations.

The Investment Manager selects investments for the Portfolio by applying the foregoing securities selection process to an investable universe of all publicly-traded equity securities, with a focus on small cap companies. However, Automated Fundamental Analysts, which may change over time, may be applied to the broad market or specific to a particular sector or industry. In addition, the selection process described above is not sequential, and certain criteria may be given more importance than others. Target position sizes are determined at the time of investment based on the input of one or more Automated Fundamental Analysts and subsequently monitored on an ongoing basis. To improve tax efficiency, the Portfolio may limit investments that have undesirable tax characteristics and may employ other tax-management techniques, such as adjusting the timing of trades, by relying in part on fundamental research and analytical judgments of the Investment Manager.
