To pursue its goal, the fund normally invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in securities issued by dividend-paying infrastructure companies. The funds sub-adviser, Newton Investment Management North America LLC (Newton), an affiliate of the Adviser, seeks to select for the fund securities of infrastructure companies that Newton believes benefit from consistent regulatory environments (a feature more common in developed markets than emerging markets), stable cash flows driven by sustainable business models, and consistent dividend payment profiles. Newton utilizes quantitative and fundamental research to select investments by focusing on infrastructure companies that it believes possess the most favorable combination of cash flow stability, dividend payment potential, and valuation metrics (such as price to earnings ratio, price to book ratio, and price to cash flow ratio). Newtons fundamental research includes evaluating key areas such as balance sheet strength, competitive landscape, stock-price valuations, liquidity, and analysis of regulatory environment. The fund is expected to invest principally in common stocks of companies, including shares of real estate investment trusts (REITs), located in a number of different countries, including the United States. Newton considers a dividend paying company to be a company that is projected to pay a dividend in the next 12 months, based on industry consensus yield forecasts.
