Factors Affecting Performance [Text Block]
What factors impacted Fund performance over the reporting period?
Country exposures and issue selection contributed to performance relative to the J.P. Morgan CEMBI Broad Diversified Index for the 12 months ended May 31, 2025. Exposures in Europe, the Middle East, and Africa contributed most to relative performance. In other regions, an underweight exposure and issue selection in Hong Kong, as well as issue selection in Indonesia, Mexico, and Brazil, enhanced performance. Some of the positive performance attribution was offset by issue selection decisions in Colombia and Argentina. In terms of industry attribution, an overweight exposure and issue selection in wireless contributed positively, as did an underweight exposure and issue selection in metals/mining/steel and financial/leasing. Underweight exposures in higher-rated credits and overweight exposures in lower-quality credits contributed to relative performance during the period.
FACTOR IMPACT SUMMARY
Indonesia


Positive


Issue selection, particularly in Cikarang Listrindo, contributed to Fund performance relative to the J.P. Morgan CEMBI Broad Diversified Index.

Mexico


Positive


Issue selection, particularly in Aeromexico, contributed to relative performance.

Colombia


Negative


Issue selection, particularly in Gran Tierra, detracted from relative performance.

Argentina Negative Issue selection, particularly in Albanesi, detracted from relative performance.

Factors Affecting Performance [Text Block]
What factors impacted Fund performance over the reporting period?
Country selection decisions contributed positively to performance relative to the J.P. Morgan EMBI Global Diversified Index for the 12 months ended May 31, 2025. Out-of-benchmark exposures to hard currency corporate debt also enhanced performance. Hard currency is generally issued by developed countries, globally traded, and seen as politically and economically stable. Some of the positive performance attribution was offset by exposure to local currency debt. Attribution from U.S. Treasuries was negative during the period. In terms of regional performance, Europe, the Middle East, and Africa – particularly an overweight and issue selection in Ghana – were considerable contributors to relative performance. In Latin America, an overweight to Ecuador was the largest contributor to performance. Underweights in several countries, including China and Indonesia, as well as issue selection in Sri Lanka, also contributed. Issue selection in Romania and Colombia detracted from performance.
FACTOR IMPACT SUMMARY
Mexico


Positive


An overweight exposure and issue selection in Mexico enhanced performance relative to the J.P. Morgan EMBI Global Diversified Index for the period.

Ecuador


Positive


An overweight exposure in Ecuador enhanced relative returns. The country outperformed when President Noboa was reelected in a second-round vote in April.

Romania


Negative


Issue selection detracted from the Fund’s relative performance.

Colombia Negative Issue selection detracted from Fund 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, detracted from performance relative to the Fund’s style-specific benchmark ("Benchmark") for the 12 months ended May 31, 2025. Within FX, overweights in the Hungarian forint and Malaysian ringgit, as well as underweights in the Chinese yuan and Colombian peso, enhanced performance. The Fund also benefited from its cash/hard currency FX exposure. Hard currency is generally issued by developed countries, globally traded, and seen as politically and economically stable. Overweight exposures in the Brazilian real and Mexican peso detracted from performance. Within duration positioning, we continued to emphasize countries with attractive after-inflation yields that we believe have sufficient space to further ease policy interest rates. Overweights in Mexico and South Africa were the biggest contributors, while overweights to Brazil and Colombia underperformed. Among the Fund’s underweight positions, Turkey was the notable outperformer, while Thailand underperformed. The markdown of the Fund’s Russian ruble cash position detracted from performance.
FACTOR IMPACT SUMMARY
South Africa


Positive


The Fund benefited from an overweight duration position relative to the Benchmark during a period of central bank policy rate cuts in South Africa.

Colombia


Positive


Issue selection contributed, but some of the positive attribution was offset by the Fund’s overweight duration position in Colombia.

Brazil


Negative


The Fund’s overweight duration position relative to the Benchmark in Brazil detracted from performance, although some of the negative attribution was offset by positive attribution from security selection and taxes.

Russia Negative The Fund marked down its Russian ruble cash position, which had been frozen due to the war in Ukraine, to zero. This was consistent with the industry standard practice, but 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, detracted from performance relative to the Fund’s style-specific benchmark ("Benchmark") for the 12 months ended May 31, 2025. Within FX, overweights in the Hungarian forint and Malaysian ringgit, as well as underweights in the Chinese yuan and Colombian peso, enhanced performance. The Fund also benefited from its cash/hard currency FX exposure. Hard currency is generally issued by developed countries, globally traded, and seen as politically and economically stable. Overweight exposures in the Brazilian real and Mexican peso detracted from performance. Within duration positioning, we continued to emphasize countries with attractive after-inflation yields that we believe have sufficient space to further ease policy interest rates. Overweights in Mexico and South Africa were the biggest contributors, while overweights to Brazil and Colombia underperformed. Among the Fund’s underweight positions, Turkey was the notable outperformer, while Thailand underperformed. The markdown of the Fund’s Russian ruble cash position detracted from performance.
FACTOR IMPACT SUMMARY
South Africa


Positive


The Fund benefited from an overweight duration position relative to the Benchmark during a period of central bank policy rate cuts in South Africa.

Colombia


Positive


Issue selection contributed, but some of the positive attribution was offset by the Fund’s overweight duration position in Colombia.

Brazil


Negative


The Fund’s overweight duration position relative to the Benchmark in Brazil detracted from performance, although some of the negative attribution was offset by positive attribution from security selection and taxes.

Russia Negative The Fund marked down its Russian ruble cash position, which had been frozen due to the war in Ukraine, to zero. This was consistent with the industry standard practice, but detracted from relative performance.
