Increase the value of its assets over the medium term by investing primarily in corporate bonds issued by socially responsible companies. The sub-fund follows a "Best-in-Class" approach which selects issuers that demonstrate superior social and environmental responsibility, while implementing robust corporate governance practices within their sector of activity. In addition, the sub-fund will select issuers (1) whose products and services contribute to resolving problems linked to environment and sustainable development, and (2) whose products and services will have positive and sustainable impacts on the environment and social climate. The sub-fund invests at least 2/3 of its assets in Investment Grade Bonds and/or securities treated as equivalent issued by companies in any country.
