Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance? 

Class A shares of the Fund returned 30.48% (unadjusted for sales charges) for the period ended August 31, 2026. The Fund's broad-based index, the MSCI EAFE Index, returned 21.62% for the same period, while the Fund's additional, more narrowly based index, the MSCI EAFE® Value Index, returned 28.49%.

Stock selection was the primary driver of the Fund’s outperformance relative to the MSCI EAFE Value Index. The Fund’s holdings outpaced the corresponding index components in seven of the ten sectors in which it held a position, with the best results occurring in materials. The French steel producer ArcelorMittal SA,* whose shares rallied on the strength of improving profit margins and robust global industrial demand, was the top contributor in the sector. Positions in several mining stocks that were propelled by rising commodity prices, including BHP Group Ltd. (2.9%) and Rio Tinto PLC (2.1%), further supported results. The Fund also outperformed in financials, led by Oversea-China Banking Ltd.* and several European banks. Health care was an additional area of strength. The Japanese company Ono Pharmaceutical Co., Ltd. (2.3%), which reported better-than-expected earnings, was the top contributor in the sector. Teva Pharmaceutical Industries Ltd. (0.3%) and Astellas Pharma, Inc. (1.9%) were additional contributors of note. Tenaris SA (1.4%), a manufacturer of steel pipes used by energy producers, was the leading contributor in the portfolio as a whole. The company reported robust earnings and received a number of analyst upgrades, boosting its shares.

On the other hand, the Fund was hurt by weaker selection in industrials. While its holdings in the sector posted a strong, double-digit gain, poor returns for certain individual stocks weighed on relative performance. Most notably, Central Japan Railway Co. (2.6%) lagged due to declining passenger demand and construction delays on a new rail line. Selection in utilities and information technology also detracted somewhat, as did positions in the French pharmaceutical giant Sanofi SA (3.8%) and the British tobacco company Imperial Brands PLC (1.9%).

Sector allocation had a neutral impact overall. While a zero weighting in real estate and an overweight in information technology contributed, an underweight in the strong-performing financials sector was a notable detractor.

Percentages in parentheses are based on the Fund’s net assets as of August 31, 2026.

* Not held at August 31, 2026.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance? 

Class R6 shares of the Fund returned 30.99% for the period ended August 31, 2026. The Fund's broad-based index, the MSCI EAFE Index, returned 21.62% for the same period, while the Fund's additional, more narrowly based index, the MSCI EAFE® Value Index, returned 28.49%.

Stock selection was the primary driver of the Fund’s outperformance relative to the MSCI EAFE Value Index. The Fund’s holdings outpaced the corresponding index components in seven of the ten sectors in which it held a position, with the best results occurring in materials. The French steel producer ArcelorMittal SA,* whose shares rallied on the strength of improving profit margins and robust global industrial demand, was the top contributor in the sector. Positions in several mining stocks that were propelled by rising commodity prices, including BHP Group Ltd. (2.9%) and Rio Tinto PLC (2.1%), further supported results. The Fund also outperformed in financials, led by Oversea-China Banking Ltd.* and several European banks. Health care was an additional area of strength. The Japanese company Ono Pharmaceutical Co., Ltd. (2.3%), which reported better-than-expected earnings, was the top contributor in the sector. Teva Pharmaceutical Industries Ltd. (0.3%) and Astellas Pharma, Inc. (1.9%) were additional contributors of note. Tenaris SA (1.4%), a manufacturer of steel pipes used by energy producers, was the leading contributor in the portfolio as a whole. The company reported robust earnings and received a number of analyst upgrades, boosting its shares.

On the other hand, the Fund was hurt by weaker selection in industrials. While its holdings in the sector posted a strong, double-digit gain, poor returns for certain individual stocks weighed on relative performance. Most notably, Central Japan Railway Co. (2.6%) lagged due to declining passenger demand and construction delays on a new rail line. Selection in utilities and information technology also detracted somewhat, as did positions in the French pharmaceutical giant Sanofi SA (3.8%) and the British tobacco company Imperial Brands PLC (1.9%).

Sector allocation had a neutral impact overall. While a zero weighting in real estate and an overweight in information technology contributed, an underweight in the strong-performing financials sector was a notable detractor.

Percentages in parentheses are based on the Fund’s net assets as of August 31, 2026.

* Not held at August 31, 2026.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance? 

Class S shares of the Fund returned 30.82% for the period ended August 31, 2026. The Fund's broad-based index, the MSCI EAFE Index, returned 21.62% for the same period, while the Fund's additional, more narrowly based index, the MSCI EAFE® Value Index, returned 28.49%.

Stock selection was the primary driver of the Fund’s outperformance relative to the MSCI EAFE Value Index. The Fund’s holdings outpaced the corresponding index components in seven of the ten sectors in which it held a position, with the best results occurring in materials. The French steel producer ArcelorMittal SA,* whose shares rallied on the strength of improving profit margins and robust global industrial demand, was the top contributor in the sector. Positions in several mining stocks that were propelled by rising commodity prices, including BHP Group Ltd. (2.9%) and Rio Tinto PLC (2.1%), further supported results. The Fund also outperformed in financials, led by Oversea-China Banking Ltd.* and several European banks. Health care was an additional area of strength. The Japanese company Ono Pharmaceutical Co., Ltd. (2.3%), which reported better-than-expected earnings, was the top contributor in the sector. Teva Pharmaceutical Industries Ltd. (0.3%) and Astellas Pharma, Inc. (1.9%) were additional contributors of note. Tenaris SA (1.4%), a manufacturer of steel pipes used by energy producers, was the leading contributor in the portfolio as a whole. The company reported robust earnings and received a number of analyst upgrades, boosting its shares.

On the other hand, the Fund was hurt by weaker selection in industrials. While its holdings in the sector posted a strong, double-digit gain, poor returns for certain individual stocks weighed on relative performance. Most notably, Central Japan Railway Co. (2.6%) lagged due to declining passenger demand and construction delays on a new rail line. Selection in utilities and information technology also detracted somewhat, as did positions in the French pharmaceutical giant Sanofi SA (3.8%) and the British tobacco company Imperial Brands PLC (1.9%).

Sector allocation had a neutral impact overall. While a zero weighting in real estate and an overweight in information technology contributed, an underweight in the strong-performing financials sector was a notable detractor.

Percentages in parentheses are based on the Fund’s net assets as of August 31, 2026.

* Not held at August 31, 2026.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance? 

Institutional Class shares of the Fund returned 30.82% for the period ended August 31, 2026. The Fund's broad-based index, the MSCI EAFE Index, returned 21.62% for the same period, while the Fund's additional, more narrowly based index, the MSCI EAFE® Value Index, returned 28.49%.

Stock selection was the primary driver of the Fund’s outperformance relative to the MSCI EAFE Value Index. The Fund’s holdings outpaced the corresponding index components in seven of the ten sectors in which it held a position, with the best results occurring in materials. The French steel producer ArcelorMittal SA,* whose shares rallied on the strength of improving profit margins and robust global industrial demand, was the top contributor in the sector. Positions in several mining stocks that were propelled by rising commodity prices, including BHP Group Ltd. (2.9%) and Rio Tinto PLC (2.1%), further supported results. The Fund also outperformed in financials, led by Oversea-China Banking Ltd.* and several European banks. Health care was an additional area of strength. The Japanese company Ono Pharmaceutical Co., Ltd. (2.3%), which reported better-than-expected earnings, was the top contributor in the sector. Teva Pharmaceutical Industries Ltd. (0.3%) and Astellas Pharma, Inc. (1.9%) were additional contributors of note. Tenaris SA (1.4%), a manufacturer of steel pipes used by energy producers, was the leading contributor in the portfolio as a whole. The company reported robust earnings and received a number of analyst upgrades, boosting its shares.

On the other hand, the Fund was hurt by weaker selection in industrials. While its holdings in the sector posted a strong, double-digit gain, poor returns for certain individual stocks weighed on relative performance. Most notably, Central Japan Railway Co. (2.6%) lagged due to declining passenger demand and construction delays on a new rail line. Selection in utilities and information technology also detracted somewhat, as did positions in the French pharmaceutical giant Sanofi SA (3.8%) and the British tobacco company Imperial Brands PLC (1.9%).

Sector allocation had a neutral impact overall. While a zero weighting in real estate and an overweight in information technology contributed, an underweight in the strong-performing financials sector was a notable detractor.

Percentages in parentheses are based on the Fund’s net assets as of August 31, 2026.

* Not held at August 31, 2026.
