The fund actively invests in government debt securities primarily issued by the Government of Canada, with minor exposure from the US Treasury. It may directly invest in government debt securities or in index funds and money market funds that primarily hold these securities. The fund aims to maintain a target duration of over ten years by employing a rules-based security selection methodology and weighting. It actively employs, at its discretion, an option strategy by writing a combination of covered call and cash-covered put options on up to approximately 50% of the value of the fund's portfolio. The manager may also choose to reconstitute and rebalance the fund's holdings from time to time. Note that the fund seeks to hedge any foreign currency exposure back to the Canadian dollar.
