Factors Affecting Performance [Text Block]

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

Despite heightened market volatility to begin the year that resulted in a short-lived bear market, U.S. equities rebound sharply from April 8 lows to finish in positive territory for a third consecutive year. The principal catalyst for the market recovery was renewed rate cuts, with the Federal Reserve lowering its policy rate by 25 basis points on three separate occasions. Robust corporate earnings, narrowing trade uncertainties, a resilient consumer, increased M&A/IPO activity, and sustained AI optimism also contributed to market strength during the year. The Fund meaningfully outperformed for a third straight year, with most of the relative gains in 2025 coming from private companies SpaceX and xAI.

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

Despite heightened market volatility to begin the year that resulted in a short-lived bear market, U.S. equities rebound sharply from April 8 lows to finish in positive territory for a third consecutive year. The principal catalyst for the market recovery was renewed rate cuts, with the Federal Reserve lowering its policy rate by 25 basis points on three separate occasions. Robust corporate earnings, narrowing trade uncertainties, a resilient consumer, increased M&A/IPO activity, and sustained AI optimism also contributed to market strength during the year. The Fund meaningfully outperformed for a third straight year, with most of the relative gains in 2025 coming from private companies SpaceX and xAI.

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

Despite heightened market volatility to begin the year that resulted in a short-lived bear market, U.S. equities rebound sharply from April 8 lows to finish in positive territory for a third consecutive year. The principal catalyst for the market recovery was renewed rate cuts, with the Federal Reserve lowering its policy rate by 25 basis points on three separate occasions. Robust corporate earnings, narrowing trade uncertainties, a resilient consumer, increased M&A/IPO activity, and sustained AI optimism also contributed to market strength during the year. The Fund meaningfully outperformed for a third straight year, with most of the relative gains in 2025 coming from private companies SpaceX and xAI.

Factors Affecting Performance [Text Block]

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

Despite heightened market volatility to begin the year that resulted in a short-lived bear market, U.S. equities rebound sharply from April 8 lows to finish in positive territory for a third consecutive year. The principal catalyst for the market recovery was renewed rate cuts, with the Federal Reserve lowering its policy rate by 25 basis points on three separate occasions. Robust corporate earnings, narrowing trade uncertainties, a resilient consumer, increased M&A/IPO activity, and sustained AI optimism also contributed to market strength during the year. The Fund meaningfully outperformed for a third straight year, with most of the relative gains in 2025 coming from private companies SpaceX and xAI.

Factors Affecting Performance [Text Block]

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

International and emerging market (EM) equities significantly outperformed their U.S. and global counterparts for first time in several years. The year was marked by a largely unexpected U.S. withdrawal from the decades-long multilateral security and trade equilibrium, which triggered a variety of defensive policy responses around the world. When the U.S. subsequently negotiated new bilateral trade agreements, or relented, and materially diluted tariff and other protectionist measures, the monetary, fiscal and reform stimulus already in the pipeline led to solid global economic growth, ultimately resulting in a much more constructive backdrop for EM and international equities. The Fund failed to keep pace with the Index in what proved to be a difficult year for quality growth investors. Performance was held back by disappointing stock selection in developed (Spain, Israel, Japan, and the U.K.) and emerging (Poland, China, and India) markets.

Factors Affecting Performance [Text Block]

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

International and emerging market (EM) equities significantly outperformed their U.S. and global counterparts for first time in several years. The year was marked by a largely unexpected U.S. withdrawal from the decades-long multilateral security and trade equilibrium, which triggered a variety of defensive policy responses around the world. When the U.S. subsequently negotiated new bilateral trade agreements, or relented, and materially diluted tariff and other protectionist measures, the monetary, fiscal and reform stimulus already in the pipeline led to solid global economic growth, ultimately resulting in a much more constructive backdrop for EM and international equities. The Fund failed to keep pace with the Index in what proved to be a difficult year for quality growth investors. Performance was held back by disappointing stock selection in developed (Spain, Israel, Japan, and the U.K.) and emerging (Poland, China, and India) markets.

Factors Affecting Performance [Text Block]

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

Real Estate trailed the broader U.S. equity market in 2025, as growth-oriented stocks, particularly those at the forefront of the AI boom, led the way. The Fund performed similarly to the Index during the year yet outperformed the MSCI US REIT Index, which was up 1.68%. The Fund failed to distance itself from the Index because solid stock selection in casinos & gaming (Wynn and Red Rock), homebuilders & land developers (Toll Brothers, Installed Building Products, and Champion Homes), and real estate services (Jones Lang LaSalle and CBRE) was mostly offset stock-specific weakness in REITs (Equinix, Vornado, Kilroy, Digital Realty, and Independence Realty Trust) and hotels & leisure (Expedia and Hyatt).

Factors Affecting Performance [Text Block]

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

Real Estate trailed the broader U.S. equity market in 2025, as growth-oriented stocks, particularly those at the forefront of the AI boom, led the way. The Fund performed similarly to the Index during the year yet outperformed the MSCI US REIT Index, which was up 1.68%. The Fund failed to distance itself from the Index because solid stock selection in casinos & gaming (Wynn and Red Rock), homebuilders & land developers (Toll Brothers, Installed Building Products, and Champion Homes), and real estate services (Jones Lang LaSalle and CBRE) was mostly offset stock-specific weakness in REITs (Equinix, Vornado, Kilroy, Digital Realty, and Independence Realty Trust) and hotels & leisure (Expedia and Hyatt).

Factors Affecting Performance [Text Block]

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

EM equities significantly outperformed their U.S. and global counterparts for first time in several years. Semiconductor-related strength in Taiwan and Korea contributed to EM’s excellent performance, overshadowing weakness in India, where equity markets were pressured by a temporary deceleration in economic growth and a related loss of earnings momentum. Poor stock selection in Poland, China, and India was largely responsible for the Fund’s relative shortfall. Meaningfully higher exposure to lagging Indian equities also proved costly. Somewhat offsetting the above was solid stock selection in Taiwan, higher exposure to strong performing Korean securities, and lack of exposure to lagging Saudi stocks.

Factors Affecting Performance [Text Block]

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

EM equities significantly outperformed their U.S. and global counterparts for first time in several years. Semiconductor-related strength in Taiwan and Korea contributed to EM’s excellent performance, overshadowing weakness in India, where equity markets were pressured by a temporary deceleration in economic growth and a related loss of earnings momentum. Poor stock selection in Poland, China, and India was largely responsible for the Fund’s relative shortfall. Meaningfully higher exposure to lagging Indian equities also proved costly. Somewhat offsetting the above was solid stock selection in Taiwan, higher exposure to strong performing Korean securities, and lack of exposure to lagging Saudi stocks.

Factors Affecting Performance [Text Block]

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

Global equities rose sharply for a third consecutive year, overcoming a swift selloff early in the period related to investor concerns about President Trump’s new tariff policies. Tariff-related fears diminished as the year wore on and the AI boom and U.S. Federal Reserve rate cuts helped push markets to fresh record highs. The Fund appreciated more than 25% and beat the Index in each of the last three years, bouncing back from a difficult stretch of absolute and relative performance in 2021 and 2022. The Fund’s U.S. holdings, specifically SpaceX and Cloudflare, were responsible for relative strength in 2025.

Tariff-related fears diminished as the year wore on and the AI boom and U.S. Federal Reserve rate cuts helped push markets to fresh record highs. The Fund appreciated more than 25% and beat the Index in each of the last three years, bouncing back from a difficult stretch of absolute and relative performance in 2021 and 2022. The Fund’s U.S. holdings, specifically SpaceX and Cloudflare, were responsible for relative strength in 2025.

Factors Affecting Performance [Text Block]

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

REITs trailed the broader U.S. equity market in 2025, as growth-oriented stocks, particularly those at the forefront of the AI boom, led the way. The Fund outperformed because of its unique exposure to non-REIT real estate companies, which were up over 18%. GDS, Wynn, Jones Lang LaSalle, Brookfield, Las Vegas Sands, CRH, and Toll Brothers led the way in the group. Stock selection in health care (American Healthcare, Ventas, and Welltower) and self-storage (SmartStop Self Storage) REITs also added value but was undone by stock-specific weakness in all other REIT categories where the Fund had investments.

Factors Affecting Performance [Text Block]

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

REITs trailed the broader U.S. equity market in 2025, as growth-oriented stocks, particularly those at the forefront of the AI boom, led the way. The Fund outperformed because of its unique exposure to non-REIT real estate companies, which were up over 18%. GDS, Wynn, Jones Lang LaSalle, Brookfield, Las Vegas Sands, CRH, and Toll Brothers led the way in the group. Stock selection in health care (American Healthcare, Ventas, and Welltower) and self-storage (SmartStop Self Storage) REITs also added value but was undone by stock-specific weakness in all other REIT categories where the Fund had investments.

Factors Affecting Performance [Text Block]

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

Health Care struggled to keep pace with the broader U.S. equity market for a third straight year, with most of the weakness coming in May, June, and July when the sector trailed the Russell 3000 Index by approximately 20%. Health Care performance was hampered by multiple factors, including regulatory uncertainty, federal investigations involving sector heavyweight UnitedHealth, cancellations/delays of National Institutes of Health grants for academic research, concerns about tariffs on the pharmaceutical industry, and renewed investor interest in AI-driven technology companies. Against this challenging backdrop, the Fund trailed the Index due to a combination of disappointing stock selection and lower exposure to strong-performing mega cap pharmaceutical stocks.

Factors Affecting Performance [Text Block]

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

Health Care struggled to keep pace with the broader U.S. equity market for a third straight year, with most of the weakness coming in May, June, and July when the sector trailed the Russell 3000 Index by approximately 20%. Health Care performance was hampered by multiple factors, including regulatory uncertainty, federal investigations involving sector heavyweight UnitedHealth, cancellations/delays of National Institutes of Health grants for academic research, concerns about tariffs on the pharmaceutical industry, and renewed investor interest in AI-driven technology companies. Against this challenging backdrop, the Fund trailed the Index due to a combination of disappointing stock selection and lower exposure to strong-performing mega cap pharmaceutical stocks.

Factors Affecting Performance [Text Block]

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

After delivering stellar performance over the 2020 to 2024 period, Indian equities experienced a phase of consolidation in 2025, driven by a temporary deceleration in economic growth and a related loss of earnings momentum. The Fund trailed the Index for the year with most of the underperformance coming in the fourth quarter when the breadth of equity returns narrowed in favor of large caps and value-oriented equities significantly outpaced growth peers. Consequently, the Fund’s sizable exposure to SMID-cap stocks and growth-oriented investment bias were key drags on relative performance.

After delivering stellar performance over the 2020 to 2024 period, Indian equities experienced a phase of consolidation in 2025, driven by a temporary deceleration in economic growth and a related loss of earnings momentum. The Fund trailed the Index for the year with most of the underperformance coming in the fourth quarter when the breadth of equity returns narrowed in favor of large caps and value-oriented equities significantly outpaced growth peers. Consequently, the Fund’s sizable exposure to SMID-cap stocks and growth-oriented investment bias were key drags on relative performance.

Factors Affecting Performance [Text Block]

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

Global equities rose sharply for a third consecutive year, overcoming a swift selloff early in the period related to investor concerns about President Trump’s new tariff policies. Tariff-related fears diminished as the year wore on and the AI boom and a series of U.S. Federal Reserve rate cuts helped push markets to new record highs. Smaller cap growth stocks trailed large caps for a fifth straight year. Given this backdrop, the Fund underperformed largely due to its elevated exposure to small- and mid-cap growth stocks via positions in Baron Growth, Small Cap, Discovery, and Asset, which together accounted for approximately 40% of average assets. Exposure to Baron Real Estate, Real Estate Income, and Health Care that are heavily invested in certain sectors that were out of favor during the year (Real Estate, REITs, and Health Care) and lower exposure to the prime beneficiaries of AI (semiconductors) also proved costly.

Factors Affecting Performance [Text Block]

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

Global equities rose sharply for a third consecutive year, overcoming a swift selloff early in the period related to investor concerns about President Trump’s new tariff policies. Tariff-related fears diminished as the year wore on and the AI boom and a series of U.S. Federal Reserve rate cuts helped push markets to new record highs. Smaller cap growth stocks trailed large caps for a fifth straight year. Given this backdrop, the Fund underperformed largely due to its elevated exposure to small- and mid-cap growth stocks via positions in Baron Growth, Small Cap, Discovery, and Asset, which together accounted for approximately 40% of average assets. Exposure to Baron Real Estate, Real Estate Income, and Health Care that are heavily invested in certain sectors that were out of favor during the year (Real Estate, REITs, and Health Care) and lower exposure to the prime beneficiaries of AI (semiconductors) also proved costly.
