Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The Global Equity Advisor Class (HLMGX) increased 2.87% (net of fees and expenses) in the six-month period ended April 30, 2026. The Fund's benchmark, the MSCI All Country World Index, rose 7.75% (net of source taxes).
Key Performance Factors
Energy and Materials soared following the US-Israeli attack on Iran and closing of the Strait of Hormuz. Consumer Discretionary lagged on concerns that increased spending on AI will pressure margins. The US market saw weak returns from large cloud-computing and data center companies, while enthusiasm for Asian technology companies boosted EMs. The Fund underperformed, with poor stocks in Communication Services, Consumer Discretionary, and Financials. The Fund’s high-quality growth style also faced a headwind, as shares of high-quality and fast-growing companies lagged the broad market.
Sector Analysis
In Communication Services, shares of Chinese internet company Tencent were pressured by concerns about its ability to profit from its aggressive AI investment. In Consumer Discretionary, shares of Japanese electronics conglomerate Sony Group declined due to rising memory costs and potential margin pressure.
Geographic Analysis
In the US, streaming company Netflix reported solid results that still fell short of market expectations. Alphabet was a bright spot as its dominant position in online search remained resilient. In EMs, Tencent and India’s HDFC Bank detracted. HDFC Bank was hurt by slower deposit growth and the resignation of its chairman; the
bank
appointed a well-regarded interim chair.

Management’s Discussion of Fund Performance
The International Equity Institutional Class (HLMIX) returned 12.83% (net of fees and expenses) in the six-month period ended April 30, 2026. The Fund's benchmark, the MSCI All Country World ex US Index, increased 12.11% (net of source taxes).
Key Performance Factors
Energy and Information Technology (IT) were the best performing sectors during the period, spurred by the rising price of oil due to the US-Iran conflict and the continued strength of AI-related companies. Communication Services declined, dragged down by the poor performance of media & entertainment companies. Shares of the fastest-growing companies significantly outperformed, while the highest-quality and most-expensive companies underperformed. The Fund’s emphasis on fast-growing companies boosted its relative performance. The Fund also outpaced the index in IT, Consumer Staples, Emerging Markets, and Europe ex EMU, but lagged in Financials, Consumer Discretionary, and Japan.
Sector Analysis
In IT, the share prices of South Korea’s Samsung Electronics and Taiwan’s Delta Electronics surged due to strong memory chip and power management demand stemming from soaring AI investment. In Financials, India's HDFC Bank detracted as it reported slower deposit growth and the resignation of its Chairman.
Geographic Analysis
UK-based mining
company
Rio Tinto gained after reporting copper-equivalent volume growth and strong cash flows. Shares of Israeli customer-service software provider NICE fell as it raised revenue guidance but forecasted lower full-year profitability due to the costs of its acquisition of Germany’s Cognigy.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The International Equity Investor Class (HLMNX) returned 12.66% (net of fees and expenses) in the six-month period ended April 30, 2026. The Fund's benchmark, the MSCI All Country World ex US Index, increased 12.11% (net of source taxes).
Key Performance Factors
Energy and Information Technology (IT) were the best performing sectors during the period, spurred by the rising price of oil due to the US-Iran conflict and the continued strength of AI-related companies. Communication Services declined, dragged down by the poor performance of media & entertainment companies. Shares of the fastest-growing companies significantly outperformed, while the highest-quality and most-expensive companies underperformed. The Fund’s emphasis on fast-growing companies boosted its relative performance. The Fund also outpaced the index in IT, Consumer Staples, Emerging Markets, and Europe ex EMU, but lagged in Financials, Consumer Discretionary, and Japan.
Sector Analysis
In IT, the share prices of South Korea’s Samsung Electronics and Taiwan’s Delta Electronics surged due to strong memory chip and power management demand stemming from soaring AI investment. In Financials, India's HDFC Bank detracted as it reported slower deposit growth and the resignation of its Chairman.
Geographic Analysis
UK-based mining company Rio Tinto gained after reporting copper-equivalent volume growth and strong cash flows. Shares of Israeli customer-service software provider NICE fell as it raised revenue guidance but forecasted lower full-year profitability due to the costs of its acquisition of Germany’s Cognigy.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The International Developed Markets Equity Institutional Class (HLIDX) returned 12.96% (net of fees and expenses) in the six-month period ended April 30, 2026. The Fund's benchmark, the MSCI World ex US Index, increased 10.72% (net of source taxes).
Key Performance Factors
Energy was the best performing sector during the period, spurred by the rising price of oil due to the US-Iran conflict. Materials also rose, with mining companies benefiting from higher gold and silver prices. Consumer Discretionary and Communication Services declined, due to the poor performance of consumer durables & apparel and media & entertainment companies, respectively. The Fund’s emphasis on fast-growing companies boosted its relative performance, while the highest-quality and most-expensive companies underperformed. The Fund also outpaced the index in Information Technology (IT), Industrials, and Europe ex EMU, but lagged in Financials, Consumer Discretionary, and Japan.
Sector Analysis
In IT, Samsung Electronics, ASML, and Disco Corp all gained strongly, reflecting broad-based strength of shares across the semiconductor supply chain. In Financials, Dutch payments processor Adyen fell sharply due to disappointing full-year guidance and concerns that AI-driven commerce could erode its competitive edge.
Geographic Analysis
UK-based mining company Rio Tinto gained after reporting copper-equivalent volume growth and strong cash flows. Shares of Israeli customer-service software provider NICE fell as it raised revenue guidance but forecasted lower full-year profitability due to the costs of its acquisition of Germany’s Cognigy.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The Institutional Emerging Markets Institutional Class (HLMEX) rose 15.23% (net of fees and expenses) in the six-month period ended April 30, 2026. The Fund's benchmark, the MSCI Emerging Markets Index, rose 15.13% in the same period (net of source taxes).
Key Performance Factors
Emerging markets rose despite dipping sharply in March in reaction to the US-Israel attack on Iran. Information Technology (IT) surged thanks to the enthusiasm for AI-related semiconductor and hardware stocks in Asia. Energy benefited from the oil price spike caused by the Middle East conflict. Communication Services and Consumer Discretionary stocks lagged. The Fund outperformed in IT and Energy, mitigating underperformance in Consumer Discretionary. The Fund’s overweight in high-quality companies was also helpful.
Sector Analysis
In IT, shares of Taiwan’s Aspeed surged on booming demand for its baseboard management chips used in AI servers. In Consumer Discretionary, Indian auto manufacturer Maruti Suzuki reported operating margins that fell short of expectations due to rising commodity prices and the temporary cost of ramping up new manufacturing facilities that should bolster the company’s growth.
Geographical Analysis
Aspeed and Delta Electronics in Taiwan both benefited from the buildout of AI infrastructure. Delta saw strong shipments for its liquid-to-air cooling systems and server power supplies. Shares of India’s HDFC Bank were pressured by slower deposit growth and the resignation of its Chairman; the bank quickly appointed a well-regarded interim chair.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance
The Frontier Emerging Markets Institutional Class (HLFMX) rose 4.28% (net of fees and expenses) in the six-month period ended April 30, 2026. The Fund's benchmark, the MSCI Frontier Emerging Markets Index, rose 15.38% in the same period (net of source taxes).
Key Performance Factors
Frontier Emerging Markets rose despite dipping sharply in March in reaction to the US-Israel attack on Iran. Energy and Real Estate were the top-performing sectors. Europe and Latin America outperformed while Asian markets were hurt by the closing of the Strait of Hormuz. The Fund lagged the index, with weak holdings in Real Estate and Consumer Discretionary. Vietnam and Indonesia also detracted. European holdings helped relative returns.
Sector Analysis
Extreme weather and inflation hurt two Philippine holdings. Real Estate company SM Prime Holdings reported weak attendance at its malls and a decline in residential construction revenue. Jollibee Foods in Consumer Discretionary experienced weak revenue growth and rising input costs. In IT, shares of Thailand-based optical communications equipment manufacturer Fabrinet rose, supported by demand for components used in cloud computing, AI, and video streaming.
Geographic Analysis
Jollibee was the main detractor in the Philippines. In Vietnam, IT services business FPT declined due to concerns over the competitive threat from AI. Shares of Kazak uranium producer Kazatomprom were buoyed by strong prices and the prospect for increased nuclear power demand for AI data centers.
