The fund is passively managed to track an index of short-term Canadian debt securities, including government and corporate bonds, with an investment-grade credit rating. Bonds should have at least one year and less than five years to maturity. Using a sampling methodology in tracking the index, the fund invests in a sample of securities that collectively have a similar investment profile to the underlying index. Using a rules-based methodology that changes over time to reflect market developments, the market-value-weighted index is rebalanced daily to add and remove securities that no longer qualify.
