Factors Affecting Performance [Text Block]

What Factors Influenced Performance?

The Fund underperformed the index due to negative alpha driven by the Fund’s tactical duration positioning. Over this prior six-month period the Fund has generally maintained higher duration exposure than its respective index due to expectations of weaker economic growth and higher inflation expectations. This increased duration exposure reduced the Fund’s performance as long-term yields increased over the reporting period.
