Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 2.49% (with sales charges) and 7.67% (without sales charges) for the six months ended July 31, 2024, compared to the Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 2.27% and the JPMorgan EMBI Global Diversified Index return of 5.33%.

• The Fund benefitted from a narrowing of credit spreads, particularly within high yield, as markets performed well despite outflows from emerging market debt funds.

• The Fund’s tilt toward local-currency denominated bonds underperformed during the period as hard-currency issues, including U.S. dollar bonds, strengthened with the central banks holding rates higher for longer.

• The Fund’s duration remained short during the period to reduce volatility, although the position adversely impacted returns as yields declined.

• Country-specific developments within the fund’s holdings contributed positively to performance.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 7.69% for the six months ended July 31, 2024, compared to the Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 2.27% and the JPMorgan EMBI Global Diversified Index return of 5.33%.

• The Fund benefitted from a narrowing of credit spreads, particularly within high yield, as markets performed well despite outflows from emerging market debt funds.

• The Fund’s duration remained short during the period to reduce volatility, although the position adversely impacted returns as yields declined.

• Country-specific developments within the fund’s holdings contributed positively to performance.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned -1.57% (with sales charges) and 2.23% (without sales charges) for the six months ended July 31, 2024, compared to the Bloomberg U.S. Aggregate Bond Index return of 1.89%.

• Interest rates were volatile over the period as investors parsed incoming economic data. The U.S. Federal Reserve remained patient throughout its four meetings over the period.

• The Fund’s selection within the Asset-Backed Securities and Commercial Mortgage-Backed Securities sectors added value to relative performance.

• The Fund’s overweight allocation in the Financials sector and selection within was additive to performance during the period.
