The fund is the first to target green bonds, or bonds that are earmarked to raise money for projects that have climate and environmental objectives and benefits. Each issuer in the underlying index is independently verified by the Climate Bonds Initiative (CBI), an international, investor-focused not-for-profit. To be considered for inclusion, the issuer must clearly indicate the rationale for the bonds green label and intended use of proceeds. CBI combines both quantitative and qualitative factors through company disclosures, public filings, sustainability reports, and independent second opinions of the security issuers. A scientific framework is the basis for definitions of which projects are consistent with a low carbon and climate resilient economy and therefore eligible for inclusion in the index. Holdings are market value weighted and rebalanced monthly. The funds adviser uses a sub-advisor to optimize trading execution and utilize stratified sampling to replicate the underlying index. The fund seeks to hedge the US dollar value of its portfolio to the Canadian dollar at all times.
