The fund provides global exposure to investment grade, labelled green bonds. It actively invests in government and corporate fixed income securities of any maturity whose proceeds are exclusively and formally applied to projects or activities that promote climate or other environmental sustainability purposes. To become a labelled green bond, issuers must apply for certification by a recognized third party, such as an auditor or ESG ratings firm. The portfolio includes debt securities of sustainable issuers the adviser believes have a fundamental value that is not reflected in their credit rating and yields. These bonds are selected by evaluating each issuers financial condition and management, its industry, and the overall economy. The fund typically invests at least 60% of its net assets in labelled green bonds and at least 10% in non-CAD debt securities. The portfolio may also include self-labelled bonds, unlabelled bonds, and other fixed income securities that are included in the Bloomberg MSCI Global Green Bond Index.
