Factors Affecting Performance [Text Block]
What factors impacted Fund performance over the reporting period?
Country exposures and issue selection contributed positively to performance relative to the J.P. Morgan CEMBI Broad Diversified Index (the "Index") for the 12 months ended May 31, 2026. Exposures in Asia contributed most to relative performance. In other regions, issue selection in Argentina and Colombia and overweights in Ghana and Ukraine enhanced performance. In terms of industry attribution, an underweight to and issue selection within financial/lease contributed, as did an overweight to and issue selection in exploration & production ("E&P"). Underweight exposures in higher-rated credits and overweight exposures in lower-quality credits contributed to relative performance for the period. Some of the positive performance attribution was offset by an overweight to Brazil and an underweight to Trinidad.
FACTOR IMPACT SUMMARY
Argentina


Positive


Issue selection, particularly in Albanesi, a thermal power and gas generator in Argentina, contributed to performance relative to the Index.

Colombia


Positive


Issue selection, particularly in Gran Tierra, an international oil and gas E&P company with main operations in Colombia and Ecuador, contributed to relative performance.

Trinidad


Negative


Issue selection, particularly in Consolidated Energy, a global natural gas-based petrochemical producer with core operations in Trinidad and Tobago, detracted from relative performance.

Brazil Negative Issue selection, particularly in Ambipar, a global environmental solutions provider based in Brazil, detracted from relative performance.

Factors Affecting Performance [Text Block]
What factors impacted Fund performance over the reporting period?
Country selection decisions were the largest contributor to performance relative to the J.P. Morgan EMBI Global Diversified Index (the "Index") for the 12 months ended May 31, 2026. Issue selection within hard currency-denominated debt was also a contributor. Hard currency bonds are debt securities issued in foreign currencies, typically U.S. dollars, rather than their local currency. Additionally, out of benchmark allocations to hard currency corporate debt in certain countries enhanced performance, while out of benchmark local currency exposure was a small detractor. Attribution from movements in U.S. Treasuries was negative during the period. In terms of regional performance, Latin America, namely an overweight and issue selection in Venezuela, was a considerable contributor to relative performance. In Europe, Middle East, and Africa, an underweight to and issue selection in Bahrain were large contributors to performance, as was an underweight to China in the Fund’s Asia allocation.
FACTOR IMPACT SUMMARY
Venezuela


Positive


Overweight exposure and issue selection in Venezuela enhanced performance relative to the Index for the period.

China


Positive


Underweight exposure in China enhanced relative returns.

Senegal


Negative


An overweight to Senegal detracted from relative performance. Delays in securing funding from the International Monetary Fund amid fiscal concerns and previously misreported deficit data weakened investor confidence.

Pakistan Negative An underweight to Pakistan detracted from relative performance.

Factors Affecting Performance [Text Block]
What factors impacted Fund performance over the reporting period?
Foreign exchange ("FX") exposure (a measurement of currency risk) and duration positioning (a measurement of adjusting the portfolio’s sensitivity to changes in interest rates), as well as security selection and taxes, all contributed to performance relative to the J.P. Morgan GBI-EM Global Diversified Index (the "Index") for the 12 months ended May 31, 2026. In FX, overweights in the Hungarian forint and Brazilian real and underweights in the Indonesian rupiah and Thai baht all enhanced performance. An overweight exposure in the Egyptian pound and underweight in the Colombian peso detracted from performance. Within duration positioning we continued to emphasize countries with attractive real (after-inflation) yields that we believe have sufficient space to further ease policy interest rates. Overweights in South Africa and Mexico were the biggest contributors, while an overweight to Paraguay was a small detractor. Within the Fund’s underweight positions, Thailand was the notable outperformer, while India underperformed.
FACTOR IMPACT SUMMARY
South Africa


Positive


The Fund’s overweight duration position relative to the Index, as well as issue selection, contributed to relative performance.

Mexico


Positive


FX and duration overweights, as well as issue selection, contributed to relative performance.

India


Negative


The Fund’s underweight duration relative to the Index, along with security selection and taxes, detracted from relative performance.

Poland Negative A duration underweight, as well as issue selection and taxes, all detracted from relative performance.

Factors Affecting Performance [Text Block]
What factors impacted Fund performance over the reporting period?
Foreign exchange ("FX") exposure (a measurement of currency risk) and duration positioning (a measurement of adjusting the portfolio’s sensitivity to changes in interest rates), as well as security selection and taxes, all contributed to performance relative to the J.P. Morgan GBI-EM Global Diversified Index (the "Index") for the 12 months ended May 31, 2026. In FX, overweights in the Hungarian forint and Brazilian real and underweights in the Indonesian rupiah and Thai baht all enhanced performance. An overweight exposure in the Egyptian pound and underweight in the Colombian peso detracted from performance. Within duration positioning we continued to emphasize countries with attractive real (after-inflation) yields that we believe have sufficient space to further ease policy interest rates. Overweights in South Africa and Mexico were the biggest contributors, while an overweight to Paraguay was a small detractor. Within the Fund’s underweight positions, Thailand was the notable outperformer, while India underperformed.
