Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The International Equity Investor Class (HLMNX) returned 4.59% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI All Country World ex US Index, increased 5.95% (net of source taxes).
Key Performance Factors
International markets gained despite uncertainty around US tariff policy and the risk that higher tariffs pose to growth. Rising long-end yields in Europe and Japan helped Financials outperform. AI-exposed companies inside China soared after the release of Chinese AI model DeepSeek, while those outside China fell sharply. Shares of the highest-quality, fastest-growing, and most expensive companies underperformed. The Fund lagged the index due to poor relative returns in Industrials and Europe ex EMU, but benefited from strong returns in Health Care, Consumer Discretionary, and Japan.
Sector Analysis
In Industrials, Hong Kong-based Techtronic Industries’ shares declined following the announcement of the Trump administration’s tariffs. Shares of Japan’s Chugai Pharmaceutical rose after its partner Lilly announced positive Phase 3 clinical trial results for Orforglipron, its oral GLP-1 candidate drug for diabetes.
Regional Analysis
Shares of Swiss hearing aid manufacturer Sonova declined due to tariff fears; the company has significant exposure to the US market. In Japan, Sony reported strong results, boosted by growth in its gaming and music divisions, and increased guidance for revenue and margins.

Management’s Discussion of Fund Performance
The Global Equity Institutional Class Z (HLGZX) increased 1.08% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI All Country World Index, increased 0.88% (net of source taxes).
Key Performance Factors
Donald Trump’s victory in the presidential election initially boosted US equities, as investors looked forward to business-friendly policies, while international markets took a more cautious view of the new administration. In April, the US government’s announcement of high tariffs on all trading partners (especially China) sent markets tumbling, though they recovered somewhat when it became clear US policymakers were open to negotiation.
Sector performance was mixed; Financials and Consumer Staples rose strongly while Information Technology, Energy, and Materials fell. The Fund outperformed the index, with good relative returns in Communication Services and Consumer Discretionary. Lagging returns in Industrials and an underweight in Financials detracted. 
Sector Analysis
In Communication Services, shares of streaming business Netflix soared in response to strong subscriber growth. Japanese electronics and media company Sony outperformed in Consumer Discretionary, boosted by growth in its gaming and music divisions.
Regional Analysis
Signs of faltering enthusiasm for artificial intelligence (AI) investments hurt French energy equipment producer Schneider Electric, which provides power and cooling technology used in advanced AI server systems. The company also underwent a leadership transition. The Fund’s underweight in AI-chip producer NVIDIA in the US was helpful.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The Global Equity Institutional Class (HLMVX) increased 1.03% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI All Country World Index, increased 0.88% (net of source taxes).
Key Performance Factors
Donald Trump’s victory in the presidential election initially boosted US equities, as investors looked forward to business-friendly policies, while international markets took a more cautious view of the new administration. In April, the US government’s announcement of high tariffs on all trading partners (especially China) sent markets tumbling, though they recovered somewhat when it became clear US policymakers were open to negotiation.
Sector performance was mixed; Financials and Consumer Staples rose strongly while Information Technology, Energy, and Materials fell. The Fund outperformed the index, with good relative returns in Communication Services and Consumer Discretionary. Lagging returns in Industrials and an underweight in Financials detracted. 
Sector Analysis
In Communication Services, shares of streaming business Netflix soared in response to strong subscriber growth. Japanese electronics and media company Sony outperformed in Consumer Discretionary, boosted by growth in its gaming and music divisions.
Regional Analysis
Signs of faltering enthusiasm for artificial intelligence (AI) investments hurt French energy equipment producer Schneider Electric, which provides power and cooling technology used in advanced AI server systems. The company also underwent a leadership transition. The Fund’s underweight in AI-chip producer NVIDIA in the US was helpful.

Management’s Discussion of Fund Performance
The Emerging Markets Advisor Class (HLEMX) fell 1.13% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI Emerging Markets Index, rose 0.40% in the same period (net of source taxes).
Key Performance Factors
Emerging markets (EMs) rose much of the period, supported by falling interest rates and the Chinese government’s launch of a large stimulus package to reignite its economy. EMs tumbled in early April after the US government announced high tariffs on all trading partners but recovered somewhat when it became clear US policymakers were open to negotiation. Communication Services was the best sector, boosted by Chinese technology leaders in the sector. The Information Technology (IT) sector fell sharply on concerns about a slowdown in AI spending. The Fund had weak relative returns in IT while good stocks in Consumer Staples were helpful.
Sector Analysis
Shares of IT-services company Globant fell due to concerns about slowing growth in the US, its key market. In Consumer Staples, bottler Coca-Cola HBC’s earnings topped market expectations.
Regional Analysis
Shares of Taiwanese semiconductor maker Aspeed were pressured by growth concerns for its AI-server end market. In India, HDFC Bank reported accelerating loan growth and has benefited from central bank efforts to improve liquidity in India’s financial system.

Management’s Discussion of Fund Performance
The International Small Companies Investor Class (HLMSX) rose 2.62% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI ACWI ex US Small Cap Index, rose 2.66% in the same period (net of source taxes).1
Key Performance Factors
International small caps gained during the period, outperforming US small caps, as investors worried about the impact of higher tariffs on US growth and inflation. European markets rallied after German legislators approved its fiscal stimulus package. Rising long-end yields in Europe and Japan helped Financials outperform. Information Technology (IT) underperformed as the release of Chinese AI model DeepSeek rattled stocks across the tech supply chain. The Fund kept pace with the index due to strong relative returns in IT and Communication Services but was hurt by weak returns in Consumer Discretionary and Industrials.
Sector Analysis
In Communication Services, mobile network operator Airtel Africa received regulatory approval to increase rates up to 50% in Nigeria. In Consumer Discretionary, Philippine home-improvement retailer Wilcon Depot reported disappointing results due to slow demand and discounting by peers.
Regional Analysis
Yantai China Pet Foods soared after the company reported strong sales and an improvement in profit margins. German life-science products manufacturer STRATEC suffered weakening pricing power; we reduced our holding.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The International Small Companies Institutional Class (HLMRX) rose 2.64% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI ACWI ex US Small Cap Index, rose 2.66% in the same period (net of source taxes).1
Key Performance Factors
International small caps gained during the period, outperforming US small caps, as investors worried about the impact of higher tariffs on US growth and inflation. European markets rallied after German legislators approved its fiscal stimulus package. Rising long-end yields in Europe and Japan helped Financials outperform. Information Technology (IT) underperformed as the release of Chinese AI model DeepSeek rattled stocks across the tech supply chain. The Fund kept pace with the index due to strong relative returns in IT and Communication Services but was hurt by weak returns in Consumer Discretionary and Industrials.
Sector Analysis
In Communication Services, mobile network operator Airtel Africa received regulatory approval to increase rates up to 50% in Nigeria. In Consumer Discretionary, Philippine home-improvement retailer Wilcon Depot reported disappointing results due to slow demand and discounting by peers.
Regional Analysis
Yantai China Pet Foods soared after the company reported strong sales and an improvement in profit margins. German life-science products manufacturer STRATEC suffered weakening pricing power; we reduced our holding.

Management’s Discussion of Fund Performance
The Frontier Emerging Markets Institutional Class (HLFMX) fell 0.82% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI Frontier Emerging Markets Index, rose 4.21% in the same period (net of source taxes).
Key Performance Factors
Frontier emerging markets, which were relatively insulated from the US trade war, outperformed developed markets. Shares of the fastest-growing and most-expensive companies underperformed. The Fund lagged the index due to poor relative returns in Information Technology (IT) and Consumer Discretionary, but benefited from strong relative returns in Industrials, Materials, and Real Estate.
Sector Analysis
IT-services company Globant faced limits to its pricing power as clients prioritized cost savings over product development, which resulted in muted margin expansion. Industrials holding Marsa Maroc, a Moroccan port operator, won a concession to operate a second terminal at the Nador West Med port on the Mediterranean coast. The expected increase in capacity will substantially increase transshipment container throughput.
Regional Analysis
By region, Asian investments detracted the most from the Fund’s performance. Philippine home-improvement retailer Wilcon Depot reported disappointing results due to weak demand and intense discounting by peers. On the other hand, UAE-based Emaar Properties has been generating strong earnings, bolstered by sustained demand for real estate in Dubai.

The Fund lagged the index due to poor relative returns in Information Technology (IT) and Consumer Discretionary, but benefited from strong relative returns in Industrials, Materials, and Real Estate.
Sector Analysis
IT-services company Globant faced limits to its pricing power as clients prioritized cost savings over product development, which resulted in muted margin expansion. Industrials holding Marsa Maroc, a Moroccan port operator, won a concession to operate a second terminal at the Nador West Med port on the Mediterranean coast. The expected increase in capacity will substantially increase transshipment container throughput.
Regional Analysis
By region, Asian investments detracted the most from the Fund’s performance. Philippine home-improvement retailer Wilcon Depot reported disappointing results due to weak demand and intense discounting by peers. On the other hand, UAE-based Emaar Properties has been generating strong earnings, bolstered by sustained demand for real estate in Dubai.

Management’s Discussion of Fund Performance
The Emerging Markets ex China Institutional Class (HLXCX) fell 2.11% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI Emerging Markets ex China Index, fell 2.43% in the same period (net of source taxes).
Key Performance Factors
Emerging markets excluding China fell, with Taiwan and South Korea hurt by waning excitement for artificial intelligence (AI)-related businesses. Emerging European markets were buoyed by Germany’s stimulus plans. The South African market continued the rise, bolstered by the stability of its new coalition government. Information Technology (IT) shares fell sharply while Communications Services and Real Estate outperformed. The Fund modestly outperformed due to good stocks in Consumer Discretionary and Real Estate. Lagging returns in IT and Health Care detracted.
Sector Analysis
Returns in Real Estate were boosted by Emaar Properties, which benefited from sustained demand for Dubai real estate. Shares of IT-services company Globant fell due to growth concerns in the US, a key market.
Regional Analysis
Coway, the leading manufacturer of air and water purifiers in South Korea, reported strong earnings growth and raised its dividend. The Fund’s underweight to Taiwanese semiconductor giant TSMC was also helpful. Bumrungrad Hospital in Thailand reported weak results due to a decline in the number of patients from abroad.

Management’s Discussion of Fund Performance
The Chinese Equity Institutional Class (HLMCX) fell 0.52% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI China All Shares Index, increased 3.16% (net of source taxes).
Key Performance Factors
Chinese stocks rose, buoyed by stronger government support for private enterprise, raising the prospect that the country may reverse its stagnating economic productivity and improve the quality of long-term growth. Additionally, AI-exposed companies inside China soared after the release of Chinese AI model DeepSeek. Shares of the highest-quality, and fastest-growing companies outperformed, while shares of the most-expensive companies underperformed. The Fund lagged the index due to poor relative returns in Information Technology, Consumer Discretionary, and Health Care, but benefited from strong relative returns in Industrials.
Sector Analysis
IT company Delta Electronics, which makes power-management components, declined on concerns about slowing growth outside of China in AI servers, a business where it has dominant share in power supplies. Sales at Inovance, a manufacturer of industrial-automation equipment, surged on strong sales growth in humanoid robots and electric vehicles.
Regional Analysis
Hong Kong-based Techtronic Industries’ shares declined following the announcement of the Trump administration’s tariffs. Chinese video game company NetEase reported strong year-over-year revenue growth for the fourth quarter, benefitting from the popularity of its new PC game Marvel Rivals.

Management’s Discussion of Fund Performance
The International Developed Markets Equity Institutional Class (HLIDX) returned 6.51% (net of fees and expenses) in the six-month period ended April 30, 2025. The Fund's benchmark, the MSCI World ex US Index, increased 8.32% (net of source taxes).
Key Performance Factors
International developed markets gained despite uncertainty around US tariff policy and the risk that higher tariffs pose to growth. Rising long-end yields in Europe and Japan helped Financials outperform. Many AI-exposed companies outside China fell sharply after the release of Chinese AI model DeepSeek. Shares of the highest-quality, fastest-growing, and most expensive companies underperformed. The Fund lagged the index due to poor relative returns in Industrials and Europe ex EMU, but benefited from strong returns in Health Care, Consumer Discretionary, and Japan.
Sector Analysis
In Industrials, Hong Kong-based Techtronic Industries’ shares declined following the announcement of the Trump administration’s tariffs. Shares of Japan’s Chugai Pharmaceutical rose after its partner Lilly announced positive Phase 3 clinical trial results for Orforglipron, its oral GLP-1 candidate drug for diabetes.
Regional Analysis
Shares of Swiss hearing aid manufacturer Sonova declined due to tariff fears; the company has significant exposure to the US market. In Japan, Sony reported strong results, boosted by growth in its gaming and music divisions, and increased guidance for revenue and margins.
