DFSB broadly invests in investment grade corporate and government debt from developed markets. The fund aims to capture returns from higher-risk and longer-term securities while making adjustments depending on their expected term and credit premiums. While the fund invests in bonds maturing within 20 years, the weighted average duration is maintained close to the Bloomberg Global Aggregate Bond Index. At least 40% are invested in non-US debt. During unfavorable market conditions, non-US exposure is reduced to at least 30%. Furthermore, the fund hedges its foreign currency exposure and may enter foreign currency forward contracts and credit default swaps. The fund may use derivatives or engage in securities lending. The advisor may make environment and other sustainability considerations that could overweight securities based on such impacts and other factors. As an actively managed fund, the portfolio managers have full discretion to make any investment decisions at any time.
