Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

  • Global fixed income markets generated positive total returns over the past 12 months as the Federal Reserve and other central banks began cutting interest rates, which broadly supported bond prices.

  • Duration and yield curve positioning benefited the fund relative to the Bloomberg Global Aggregate Bond USD Hedged Index. Tactically, adjusting the fund’s U.S. duration posture and positioning the fund to benefit from a steepening U.S. Treasury yield curve at times contributed over the period. Active currency management, specifically in the euro, Egyptian pound, and Japanese yen, also added value as the U.S. dollar came under pressure in 2025.

  • The fund’s allocations in corporate credit weighed on performance versus the benchmark. While investment-grade and high yield corporate bonds were generally supportive in the first half of the period, increased market volatility and economic uncertainty pressured credit sectors more recently.

  • The fund seeks to provide high income and some capital appreciation through a broadly diversified portfolio of domestic and foreign debt instruments, including exposure to various bond sectors, countries, and currencies. By the end of the period, we had a more cautious and defensive positioning within corporate credit.

  • The fund held derivatives during the period, including currency, interest rate, and credit derivatives. The fund’s derivatives exposure, including credit and currency derivatives, weighed on absolute performance. However, interest rate derivatives aided absolute returns.
