Management's discussion of Fund performance
Performance highlights
Nomura Global Listed Real Assets Fund (Class R6) returned 11.56% (excluding sales charge) for the 12 months ended October 31, 2025. During the same period, the MSCI ACWI (All Country World Index) Index (net) and MSCI ACWI Index (gross), the Fund's broad-based securities market index, returned 22.64% and 23.19%, respectively, while the Bloomberg Global Inflation-Linked Total Return Index Value Hedged USD, the Fund's narrowly based securities market index, returned 3.49%.
Top contributors to performance:
Equities and credit-sensitive fixed income generally rallied over the fiscal year, supported by stabilizing inflation expectations and a broad trend of monetary easing by central banks globally.
Real asset equities and real asset credit generally drove outperformance relative to inflation-linked bonds as the momentum behind strong corporate earnings and falling yields helped propel risk assets forward.
Relative to the Fund's narrowly based index:
Overweight to real asset equities, including infrastructure, natural resources, and real estate
Overweight to real asset credit
Top detractors from performance:
The Fund’s allocation to real estate underperformed the Fund’s broad-based index.
The Fund’s allocation to inflation-linked fixed income underperformed the Fund’s narrowly based index.
Security selection within inflation-linked fixed income slightly detracted.
Within sectors, paper and forest products as well as containers and packaging detracted.

Management's discussion of Fund performance
Performance highlights
Nomura Global Listed Real Assets Fund (Class C) returned 10.31% (excluding sales charge) for the 12 months ended October 31, 2025. During the same period, the MSCI ACWI (All Country World Index) Index (net) and MSCI ACWI Index (gross), the Fund's broad-based securities market index, returned 22.64% and 23.19%, respectively, while the Bloomberg Global Inflation-Linked Total Return Index Value Hedged USD, the Fund's narrowly based securities market index, returned 3.49%.
Top contributors to performance:
Equities and credit-sensitive fixed income generally rallied over the fiscal year, supported by stabilizing inflation expectations and a broad trend of monetary easing by central banks globally.
Real asset equities and real asset credit generally drove outperformance relative to inflation-linked bonds as the momentum behind strong corporate earnings and falling yields helped propel risk assets forward.
Relative to the Fund's narrowly based index:
Overweight to real asset equities, including infrastructure, natural resources, and real estate
Overweight to real asset credit
Top detractors from performance:
The Fund’s allocation to real estate underperformed the Fund’s broad-based index.
The Fund’s allocation to inflation-linked fixed income underperformed the Fund’s narrowly based index.
Security selection within inflation-linked fixed income slightly detracted.
Within sectors, paper and forest products as well as containers and packaging detracted.
Performance Past Does Not Indicate Future [Text] Keep in mind that the Fund's past performance is not a good predictor of how the Fund will perform in the future.
