Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

The U.S. investment-grade bond market delivered positive returns over the 12-month period, driven primarily by attractive coupon income as yields began near multiyear highs. A resilient economy, solid issuer fundamentals, and strong demand for high-quality fixed income securities also supported performance, although rising Treasury yields later in the period created some headwinds.
Out-of-benchmark allocations to high yield corporate bonds and non-agency residential mortgage-backed securities combined with an underweight to U.S. Treasuries contributed to performance relative to the Bloomberg U.S. Aggregate Bond Index. Security selection in emerging markets sovereign debt, along with an overweight to the sector, also added value, as did selection within investment-grade corporates.
Tactical adjustments to the fund’s duration position as well as the portfolio’s use of Treasury futures to manage interest rate exposure detracted from relative performance versus the benchmark. An underweight to investment-grade corporate cash bonds also hurt performance.
The fund invests in a diversified portfolio of bonds and other debt instruments and is designed to respond to a wide variety of market conditions. At period-end, portfolio positioning reflected a favorable view on credit risk, and the fund held notable overweights to securitized credit sectors along with out-of-benchmark positions in high yield bonds and bank loans.
Overall, the fund held material exposure to derivatives, including interest rate and credit derivatives that help the investment team more efficiently manage duration and sector positioning. The fund’s positions in interest rate derivatives weighed on absolute performance.
