The objective of the investment policy is to achieve an above average appreciation of capital. In order to achieve this, the sub-fund invests at least 80% of its net asset value worldwide in shares of issuers that are related to the so-called blue economy, as qualitatively assessed by DWS internal research. For the purpose of the sub-funds asset allocation, the term blue economy refers to companies with economic activities that can take place both on land or in the oceans and have a direct or indirect link to maritime ecosystems.
