Strategy. The US Sustainable Economy Fund follows a sustainable investing approach, investing in companies that the Adviser believes are well positioned to benefit from the transition to a more sustainable economy, integrating environmental, social and governance (ESG) analysis into portfolio construction and managing the portfolio within certain risk parameters (e.g., sector and regional exposure) relative to the Funds benchmark universe of Russell 1000 Index companies.

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in large-capitalization US equity securities. The Fund also may invest up to 20% of its assets in non-US issuers, including emerging market investments and American Depository Receipts (ADRs). The Fund employs a systematic investment strategy that integrates proprietary and external tools and metrics in the portfolio construction process. The Fund incorporates the Impax Sustainability Lens, a tool utilized by the Adviser to facilitate a systematic review of the economic opportunities and risks associated with the transition to a more sustainable economy. The tool highlights sub-industries with transition tailwinds and headwinds, enabling the investment team to construct a portfolio weighted towards companies that the Adviser believes present attractive opportunities and lower risks. The Fund may take significant positions in one or more sectors, including the information technology sector. The Funds investment team also utilizes the Impax Systematic ESG Score, a fundamental, bottom-up score by the Adviser of a companys ESG profile. The score emphasizes management of ESG-related risks, incorporates ESG trends (taking into account progress or regression in a companys ESG profile) and takes into account any involvement by the company in significant ESG-related controversies. Under normal market conditions, and as a result of the Advisers focus on the risks and opportunities accompanying the transition to a more sustainable economy, the Fund adheres to the Impax Funds fossil fuel policy, under which the Fund will not invest in securities of companies that the Adviser determines derive revenues or profits from fossil fuel exploration and production, or derive significant (more than 5%) revenues or profits from fossil fuel refining, processing, storage, transportation and distribution. However, a company that derives significant revenues or profits from fossil fuel refining, processing, storage, transportation and distribution may be included in the Funds portfolio if the Adviser determines that such company has credible plans for climate risk mitigation aligned with the transition to net zero.
