The fund tracks an index of Canadian investment-grade bonds of various maturities. The fund offers broad exposure to the fixed income market by investing in liquid corporate and government bonds domiciled in Canada, excluding CAD-denominated securities by foreign issuers (also known as maple bonds). Government securities include provincial and municipal bonds. Bonds must pass the issuer-based screening from ISS-ESG that uses norm-based and controversial weapon research, as well as activity-based screening. Companies considered must include at least one woman in upper management. Remaining securities then are ranked within each sector according to their carbon intensity. The highest ranked securities are selected. The fund uses a sampling methodology, which means it can invest in a sample of securities with a similar investment profile to that of the underlying index. The index is rebalanced monthly.
