The Fund seeks to maximize total return by primarily investing in companies that BFA believes are expected to enable and/or benefit from the transition to a lower greenhouse gas emissions economy. The Fund focuses its investments on companies that are driving the reduction of greenhouse gases across all segments of the market and that provide solutions for the mitigation and/or adaptation to climate change, climate change risk or which are in the process of making their business models more resilient to the long-term risks presented by climate change and resource depletion. In normal market conditions, the Fund will seek to invest in a relatively concentrated portfolio of equity securities across multiple sub-themes driven by this future climate theme, including (without limitation) clean power, resource efficiency, sustainable nutrition, biodiversity and clean transport.
