| Factors Affecting Performance [Text Block] | How did the Fund perform last year? International equities broadly moved higher as the period progressed, resulting in significant positive returns across most market segments. Major overseas economies returned to positive growth, supporting the corporate earnings outlook. Signs of easing inflation led to expectations that leading central banks were poised to begin reducing interest rates, leading growth-oriented stocks to outperform dividend payers. What contributed to performance? Positive contributions to performance, relative to the benchmark (MSCI ACWI ex USA Index) were led by stock selection in information technology, industrials and materials. In terms of individual holdings, Danish pharmaceutical company Novo Nordisk benefited from increased demand for its diabetes and obesity products, including Wegovy which is increasingly available outside the United States. ASML, the Dutch manufacturer of silicon photolithography systems used in semiconductor manufacturing, reported revenues and earnings that exceeded expectations, driven by record order growth. Results for British arms, security and aerospace company BAE Systems have been boosted by conflicts in Ukraine and the Middle East as governments bolster their military capabilities. What detracted from performance? The largest detractors from performance included stock selection within and underweights to financials and consumer staples. With respect to specific holdings, Swiss pharmaceutical and biotech company Lonza Biologics experienced the unexpected departure of its CEO and downgraded 2024 guidance at its Capital Markets Day. The downgrade was centered on the biologics division which management had previously indicated was fully booked for the foreseeable future, and the Fund exited the position. U.K.-based multinational insurance company Prudential Financial came under pressure due to weaker sentiment around China. Bank Rakyat, the Indonesian bank that specializes in small scale and microfinance lending, indicated that inconsistent underwriting practices (since rectified) in its rural loan program would likely lead to increased credit losses in coming months.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Energy stocks delivered robust returns, albeit with elevated volatility, thanks to gains in both crude oil prices and the equity market more broadly. What contributed to performance? A zero weighting in Woodside Energy Group, Ltd. Contributed to performance, as did an underweight in Chevron Corp. An overweight in the midstream distribution company Williams Cos. also contributed to relative performance given its significant exposure to natural gas pipelines. What detracted from performance? The Fund held no positions in the refining company Phillips66, which rallied due to moves from an activist investor, which detracted from performance. A zero weighting in the Canadian integrated oil company Suncor Energy, Inc. detracted, as the stock rose on the strength of higher oil prices. Lack of positions in the Canadian uranium producer Cameco Corp., was an additional detractor, as the United States’ ban on Russia uranium imports was seen as a positive for the company.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Healthcare stocks, while producing a strong absolute return, did not keep pace with the broader market at a time in which technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sub-sector level, security selection in pharmaceuticals contributed to results. On a stock-specific basis, an underweight position in Bristol Myers Squibb Co. was the top contributor to performance. The biopharmaceutical company missed sales expectations for select treatments and faced elevated competition from generic drugs. An overweight position in Boston Scientific Corp. was another leading contributor. The medical device company reported robust sales growth in its surgery and cardiovascular segments and received approval for a new treatment from the Food and Drug Administration. What detracted from performance? Selection in the biotechnology sub-sector detracted. Among individual positions, an overweight in the biotechnology stock Biogen, Inc.—which was hurt by slower-than-expected sales for its Alzheimer’s treatment Leqembi—was the largest detractor. An overweight position in Penumbra, Inc. also hurt results. The medical device company missed first-quarter earnings estimates due to a decline in its international sales.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Infrastructure stocks, while producing a positive absolute return, did not keep pace with the broader market at a time in which information technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sector level, Eurozone highways, U.S. data centers, and Australian communications were the largest contributors. Among individual stocks, Ferrovial SE, Enel SpA, and Digital Realty Trust, Inc. were the leading contributors. The Fund’s cash position had no material impact on performance. What detracted from performance? Eurozone electric utilities, U.K. diversified utilities and Eurozone communications were the largest detractors. Energias de Portugal SA, EDP Renováveis SA, and Orsted SA were the most notable detractors at the individual stock level. The Fund’s use of derivatives marginally detracted from performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. What contributed to performance? The Fund’s performance was driven by fundamental stock selection. Long positions in Nvidia Corp. and Amazon.com, Inc. proved beneficial amid the broader excitement around artificial intelligence. Elsewhere, long positions in energy companies Conocophillips Company and Suncor Energy Inc. also contributed positively. Gains from fundamental stock selection were compounded by systematic insights. Sentiment-based measures evaluating trends across analyst and executive comments as well as macro thematic insights measuring hiring trends and business-to-business invoicing collectively were key performance drivers. These insights broadly helped the Fund identify the dominant trends of what became an increasingly trending market. Finally, the Fund used derivatives to implement market timing models expressed in futures. These instruments contributed slightly to performance. The Fund’s cash position had no material impact on performance. What detracted from performance? While fundamental stock selection contributed in aggregate, select positions detracted from performance, including a net long to media company Comcast and a short to oil stock CNX Resources Corp. Elsewhere, systematic measures evaluating traditional financial statement data such as cash flows, valuations and dividend consistency ran against the prevailing market themes.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? U.S. equities broadly moved higher as the period progressed, resulting in significant positive returns across most market segments. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates, leading growth-oriented stocks to outperform value stocks. What contributed to performance? Positive contributions to the Fund’s performance relative to the benchmark (Russell 1000 ® What detracted from performance? The Fund’s overweight to and security selection with the healthcare sector detracted the most, with positioning in the healthcare equipment and supplies industry weighing most heavily on performance. Security selection within consumer staples also detracted from performance, particularly within the distribution and retail industry. Approximately 30% of the Fund is overwritten using a covered call strategy designed to provide a consistent stream of income. The use of covered calls detracted from performance as expected during a rising market environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Energy stocks delivered robust returns, albeit with elevated volatility, thanks to gains in both crude oil prices and the equity market more broadly. What contributed to performance? A zero weighting in Woodside Energy Group, Ltd. Contributed to performance, as did an underweight in Chevron Corp. An overweight in the midstream distribution company Williams Cos. also contributed to relative performance given its significant exposure to natural gas pipelines. What detracted from performance? The Fund held no positions in the refining company Phillips66, which rallied due to moves from an activist investor, which detracted from performance. A zero weighting in the Canadian integrated oil company Suncor Energy, Inc. detracted, as the stock rose on the strength of higher oil prices. Lack of positions in the Canadian uranium producer Cameco Corp., was an additional detractor, as the United States’ ban on Russia uranium imports was seen as a positive for the company.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equity market sentiment was supported as fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. Within the growth stock universe, performance was led by a handful of mega-cap technology companies viewed as the likely principal beneficiaries of efforts to commercialize the use of artificial intelligence. What contributed to performance? Positive contributions to the Fund’s performance relative to the benchmark (Russell Midcap ® What detracted from performance? The largest detractors from relative performance included stock selection in consumer discretionary and real estate, as well as positioning in energy. Within consumer discretionary, an out-of-benchmark benchmark position in Swedish online gaming solutions provider Evolution within the hotels, restaurants and leisure sub-sector weighed most heavily on returns. An overweight position to CoStar Group within real estate management and development was the biggest detractor. Lastly, an underweight to the energy sector, most notably to the oil, gas and consumable fuels sub-sector, detracted from relative performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Commodities produced a strong, broad-based gain during the reporting period, reflecting positive supply-and-demand trends. Natural resource stocks delivered robust returns, albeit with elevated volatility, thanks to the gains in both commodity prices and the equity market more broadly. What contributed to performance? The Fund invested in both commodity derivatives and natural resources equities, with a weighting of approximately 50% in each. Positions in energy stocks delivered the most meaningful outperformance, as the Fund’s holdings in some of the larger integrated energy companies benefitted from robust oil prices. The Fund’s holdings in precious metals (both commodity-linked derivatives and mining companies) also delivered strong relative returns. The gold price increased approximately 20% over the period, driven by strong investment demand and plateauing interest rates. The Fund’s cash position had no material impact on performance. What detracted from performance? The Fund’s holdings in agriculture stocks detracted. While grain prices were relatively rangebound, companies with exposure to the onshore China market came under pressure.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. What contributed to performance? The Fund’s performance was driven by fundamental stock selection. Long positions in Nvidia Corp. and Amazon.com, Inc. proved beneficial amid the broader excitement around artificial intelligence. Elsewhere, long positions in energy companies Conocophillips Company and Suncor Energy Inc. also contributed positively. Gains from fundamental stock selection were compounded by systematic insights. Sentiment-based measures evaluating trends across analyst and executive comments as well as macro thematic insights measuring hiring trends and business-to-business invoicing collectively were key performance drivers. These insights broadly helped the Fund identify the dominant trends of what became an increasingly trending market. Finally, the Fund used derivatives to implement market timing models expressed in futures. These instruments contributed slightly to performance. The Fund’s cash position had no material impact on performance. What detracted from performance? While fundamental stock selection contributed in aggregate, select positions detracted from performance, including a net long to media company Comcast and a short to oil stock CNX Resources Corp. Elsewhere, systematic measures evaluating traditional financial statement data such as cash flows, valuations and dividend consistency ran against the prevailing market themes.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Technology stocks, particularly those expected to benefit from the growing use of artificial intelligence, strongly outpaced the broader equity market. What contributed to performance? At the sub-sector level, an underweight allocation to hardware stocks contributed to results. On a stock-specific basis, an underweight position in Apple, Inc., which lagged due in part to increased competition in China, was the top contributor to performance. An off-benchmark position in Meta Platforms, Inc. was another leading contributor. The internet company reported artificial intelligence-driven improvements in monetization across its social media platforms, announced significant cost reductions, and paid its first dividend. What detracted from performance? An overweight allocation to the new industries subsector detracted. Among individual positions, an overweight in the semiconductor stock Wolfspeed, Inc.—which was hurt by weakness in the electric vehicle market—was the largest detractor. An overweight position in Adyen NV also hurt results. The Dutch financial-technology company faced subdued demand as price-sensitive customers migrated to lower-cost competitors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Healthcare stocks, while producing a strong absolute return, did not keep pace with the broader market at a time in which technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sub-sector level, security selection in pharmaceuticals contributed to results. On a stock-specific basis, an underweight position in Bristol Myers Squibb Co. was the top contributor to performance. The biopharmaceutical company missed sales expectations for select treatments and faced elevated competition from generic drugs. An overweight position in Boston Scientific Corp. was another leading contributor. The medical device company reported robust sales growth in its surgery and cardiovascular segments and received approval for a new treatment from the Food and Drug Administration. What detracted from performance? Selection in the biotechnology sub-sector detracted. Among individual positions, an overweight in the biotechnology stock Biogen, Inc.—which was hurt by slower-than-expected sales for its Alzheimer’s treatment Leqembi—was the largest detractor. An overweight position in Penumbra, Inc. also hurt results. The medical device company missed first-quarter earnings estimates due to a decline in its international sales.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Technology stocks, particularly those expected to benefit from the growing use of artificial intelligence, strongly outpaced the broader equity market. What contributed to performance? At the sub-sector level, an underweight allocation to hardware stocks contributed to results. On a stock-specific basis, an underweight position in Apple, Inc., which lagged due in part to increased competition in China, was the top contributor to performance. An off-benchmark position in Meta Platforms, Inc. was another leading contributor. The internet company reported artificial intelligence-driven improvements in monetization across its social media platforms, announced significant cost reductions, and paid its first dividend. What detracted from performance? An overweight allocation to the new industries subsector detracted. Among individual positions, an overweight in the semiconductor stock Wolfspeed, Inc.—which was hurt by weakness in the electric vehicle market—was the largest detractor. An overweight position in Adyen NV also hurt results. The Dutch financial-technology company faced subdued demand as price-sensitive customers migrated to lower-cost competitors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Healthcare stocks, while producing a strong absolute return, did not keep pace with the broader market at a time in which technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sub-sector level, security selection in pharmaceuticals contributed to results. On a stock-specific basis, an underweight position in Bristol Myers Squibb Co. was the top contributor to performance. The biopharmaceutical company missed sales expectations for select treatments and faced elevated competition from generic drugs. An overweight position in Boston Scientific Corp. was another leading contributor. The medical device company reported robust sales growth in its surgery and cardiovascular segments and received approval for a new treatment from the Food and Drug Administration. What detracted from performance? Selection in the biotechnology sub-sector detracted. Among individual positions, an overweight in the biotechnology stock Biogen, Inc.—which was hurt by slower-than-expected sales for its Alzheimer’s treatment Leqembi—was the largest detractor. An overweight position in Penumbra, Inc. also hurt results. The medical device company missed first-quarter earnings estimates due to a decline in its international sales.

Equity market sentiment was supported as fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. Within the growth stock universe, performance was led by a handful of mega-cap technology companies viewed as the likely principal beneficiaries of efforts to commercialize the use of artificial intelligence. What contributed to performance? Positive contributions to performance, relative to the benchmark (Russell 2500 TM What detracted from performance? The largest detractors from relative performance included stock selection in consumer discretionary, information technology and consumer staples. Within consumer discretionary, an overweight to the hotels, restaurants and leisure industry, specifically an overweight position in Vail Resorts, detracted from relative returns. Next, within information technology, lack of exposure to the technology hardware, storage and peripherals sub-sector weighed most heavily on performance. Lastly, selection in consumer staples, most notably an out-of-benchmark position in Davide Campari Milano within the beverages sub-sector, detracted from relative performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Technology stocks, particularly those expected to benefit from the growing use of artificial intelligence, strongly outpaced the broader equity market. What contributed to performance? At the sub-sector level, an underweight allocation to hardware stocks contributed to results. On a stock-specific basis, an underweight position in Apple, Inc., which lagged due in part to increased competition in China, was the top contributor to performance. An off-benchmark position in Meta Platforms, Inc. was another leading contributor. The internet company reported artificial intelligence-driven improvements in monetization across its social media platforms, announced significant cost reductions, and paid its first dividend. What detracted from performance? An overweight allocation to the new industries subsector detracted. Among individual positions, an overweight in the semiconductor stock Wolfspeed, Inc.—which was hurt by weakness in the electric vehicle market—was the largest detractor. An overweight position in Adyen NV also hurt results. The Dutch financial-technology company faced subdued demand as price-sensitive customers migrated to lower-cost competitors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. What contributed to performance? Positive contributions to performance, relative to the benchmark (MSCI EAFE Index) were led by sentiment measures that were able to identify dominant trends by looking at informed investor positioning and through text-based analysis of broker reports (or conference calls). These insights correctly positioned the portfolio around Japanese stocks within financials and industrials that benefited as the theme of corporate reform continued to materialize in the region. Traditional fundamental measures also were additive, notably by driving positioning in U.K. consumer staples companies. An insight looking at research and development spending correctly positioned the portfolio in European healthcare stocks that benefited from enthusiasm around the use of GLP-1 drugs for weight loss. Finally, traditional quality insights looking at external financing correctly positioned the portfolio within information technology, particularly with respect to Japanese semiconductor companies likely to benefit from the emerging artificial intelligence theme. What detracted from performance? The largest detractors from relative performance included certain non-traditional fundamental quality insights, most notably those related to human capital such as those looking at veteran hiring, employee sentiment and hiring for environmental roles. In addition, changing market leadership proved a headwind to trend-following industry insights, with industry measures picking up on price momentum and favoring defensive positioning among the biggest laggards.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equity market sentiment was supported as fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. Within the growth stock universe, performance was led by a handful of mega-cap technology companies viewed as the likely principal beneficiaries of efforts to commercialize the use of artificial intelligence. What contributed to performance? Positive contributions to the Fund’s performance relative to the benchmark (Russell Midcap ® What detracted from performance? The largest detractors from relative performance included stock selection in consumer discretionary and real estate, as well as positioning in energy. Within consumer discretionary, an out-of-benchmark benchmark position in Swedish online gaming solutions provider Evolution within the hotels, restaurants and leisure sub-sector weighed most heavily on returns. An overweight position to CoStar Group within real estate management and development was the biggest detractor. Lastly, an underweight to the energy sector, most notably to the oil, gas and consumable fuels sub-sector, detracted from relative performance.

U.S. equities broadly moved higher as the period progressed, resulting in significant positive returns across most market segments. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates, leading growth-oriented stocks to outperform value stocks. What contributed to performance? Positive contributions to the Fund’s performance relative to the benchmark (Russell 1000 ® What detracted from performance? The Fund’s overweight to and security selection with the healthcare sector detracted the most, with positioning in the healthcare equipment and supplies industry weighing most heavily on performance. Security selection within consumer staples also detracted from performance, particularly within the distribution and retail industry. Approximately 30% of the Fund is overwritten using a covered call strategy designed to provide a consistent stream of income. The use of covered calls detracted from performance as expected during a rising market environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Technology stocks, particularly those expected to benefit from the growing use of artificial intelligence, strongly outpaced the broader equity market. What contributed to performance? At the sub-sector level, an underweight allocation to hardware stocks contributed to results. On a stock-specific basis, an underweight position in Apple, Inc., which lagged due in part to increased competition in China, was the top contributor to performance. An off-benchmark position in Meta Platforms, Inc. was another leading contributor. The internet company reported artificial intelligence-driven improvements in monetization across its social media platforms, announced significant cost reductions, and paid its first dividend. What detracted from performance? An overweight allocation to the new industries subsector detracted. Among individual positions, an overweight in the semiconductor stock Wolfspeed, Inc.—which was hurt by weakness in the electric vehicle market—was the largest detractor. An overweight position in Adyen NV also hurt results. The Dutch financial-technology company faced subdued demand as price-sensitive customers migrated to lower-cost competitors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. What contributed to performance? Positive contributions to performance, relative to the benchmark (MSCI EAFE Index) were led by sentiment measures that were able to identify dominant trends by looking at informed investor positioning and through text-based analysis of broker reports (or conference calls). These insights correctly positioned the portfolio around Japanese stocks within financials and industrials that benefited as the theme of corporate reform continued to materialize in the region. Traditional fundamental measures also were additive, notably by driving positioning in U.K. consumer staples companies. An insight looking at research and development spending correctly positioned the portfolio in European healthcare stocks that benefited from enthusiasm around the use of GLP-1 drugs for weight loss. Finally, traditional quality insights looking at external financing correctly positioned the portfolio within information technology, particularly with respect to Japanese semiconductor companies likely to benefit from the emerging artificial intelligence theme. What detracted from performance? The largest detractors from relative performance included certain non-traditional fundamental quality insights, most notably those related to human capital such as those looking at veteran hiring, employee sentiment and hiring for environmental roles. In addition, changing market leadership proved a headwind to trend-following industry insights, with industry measures picking up on price momentum and favoring defensive positioning among the biggest laggards.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? U.S. equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates, leading growth-oriented stocks to outperform value stocks. What contributed to performance? Positive contributions to performance, relative to the benchmark (Russell 1000 ® What detracted from performance? The largest detractors from relative performance were certain fundamental insights including defensive quality measures that prefer balance sheet strength and more stable companies. Certain sentiment measures looking at bond markets struggled to position the portfolio as the market narrative shifted between the “soft landing” and “higher-for-longer” themes.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? International equities broadly moved higher as the period progressed, resulting in significant positive returns across most market segments. Major overseas economies returned to positive growth, supporting the corporate earnings outlook. Signs of easing inflation led to expectations that leading central banks were poised to begin reducing interest rates, leading growth-oriented stocks to outperform dividend payers. What contributed to performance? Positive contributions to performance, relative to the benchmark (MSCI ACWI ex USA Index) were led by stock selection in information technology, industrials and materials. In terms of individual holdings, Danish pharmaceutical company Novo Nordisk benefited from increased demand for its diabetes and obesity products, including Wegovy which is increasingly available outside the United States. ASML, the Dutch manufacturer of silicon photolithography systems used in semiconductor manufacturing, reported revenues and earnings that exceeded expectations, driven by record order growth. Results for British arms, security and aerospace company BAE Systems have been boosted by conflicts in Ukraine and the Middle East as governments bolster their military capabilities. What detracted from performance? The largest detractors from performance included stock selection within and underweights to financials and consumer staples. With respect to specific holdings, Swiss pharmaceutical and biotech company Lonza Biologics experienced the unexpected departure of its CEO and downgraded 2024 guidance at its Capital Markets Day. The downgrade was centered on the biologics division which management had previously indicated was fully booked for the foreseeable future, and the Fund exited the position. U.K.-based multinational insurance company Prudential Financial came under pressure due to weaker sentiment around China. Bank Rakyat, the Indonesian bank that specializes in small scale and microfinance lending, indicated that inconsistent underwriting practices (since rectified) in its rural loan program would likely lead to increased credit losses in coming months.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Infrastructure stocks, while producing a positive absolute return, did not keep pace with the broader market at a time in which information technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sector level, Eurozone highways, U.S. data centers, and Australian communications were the largest contributors. Among individual stocks, Ferrovial SE, Enel SpA, and Digital Realty Trust, Inc. were the leading contributors. The Fund’s cash position had no material impact on performance. What detracted from performance? Eurozone electric utilities, U.K. diversified utilities and Eurozone communications were the largest detractors. Energias de Portugal SA, EDP Renováveis SA, and Orsted SA were the most notable detractors at the individual stock level. The Fund’s use of derivatives marginally detracted from performance.

Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Healthcare stocks, while producing a strong absolute return, did not keep pace with the broader market at a time in which technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sub-sector level, security selection in pharmaceuticals contributed to results. On a stock-specific basis, an underweight position in Bristol Myers Squibb Co. was the top contributor to performance. The biopharmaceutical company missed sales expectations for select treatments and faced elevated competition from generic drugs. An overweight position in Boston Scientific Corp. was another leading contributor. The medical device company reported robust sales growth in its surgery and cardiovascular segments and received approval for a new treatment from the Food and Drug Administration. What detracted from performance? Selection in the biotechnology sub-sector detracted. Among individual positions, an overweight in the biotechnology stock Biogen, Inc.—which was hurt by slower-than-expected sales for its Alzheimer’s treatment Leqembi—was the largest detractor. An overweight position in Penumbra, Inc. also hurt results. The medical device company missed first-quarter earnings estimates due to a decline in its international sales.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Healthcare stocks, while producing a strong absolute return, did not keep pace with the broader market at a time in which technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sub-sector level, security selection in pharmaceuticals contributed to results. On a stock-specific basis, an underweight position in Bristol Myers Squibb Co. was the top contributor to performance. The biopharmaceutical company missed sales expectations for select treatments and faced elevated competition from generic drugs. An overweight position in Boston Scientific Corp. was another leading contributor. The medical device company reported robust sales growth in its surgery and cardiovascular segments and received approval for a new treatment from the Food and Drug Administration. What detracted from performance? Selection in the biotechnology sub-sector detracted. Among individual positions, an overweight in the biotechnology stock Biogen, Inc.—which was hurt by slower-than-expected sales for its Alzheimer’s treatment Leqembi—was the largest detractor. An overweight position in Penumbra, Inc. also hurt results. The medical device company missed first-quarter earnings estimates due to a decline in its international sales.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? U.S. equities broadly moved higher as the reporting period progressed, resulting in significant positive returns across most market segments. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates, driving outperformance by mega-cap growth stocks within information technology and communications services. What contributed to performance? Positive contributions to performance, relative to the benchmark (Russell 2000 ® What detracted from performance? The largest detractors from relative performance included fundamental quality insights, most notably defensive quality measures focusing on cash flows and debt maturities which drove unsuccessful stock selection within healthcare amid enthusiasm around the use of GLP-1 drugs for weight loss. Nontraditional measures with a preference for founder-led company management also detracted.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Technology stocks, particularly those expected to benefit from the growing use of artificial intelligence, strongly outpaced the broader equity market. What contributed to performance? At the sub-sector level, an underweight allocation to hardware stocks contributed to results. On a stock-specific basis, an underweight position in Apple, Inc., which lagged due in part to increased competition in China, was the top contributor to performance. An off-benchmark position in Meta Platforms, Inc. was another leading contributor. The internet company reported artificial intelligence-driven improvements in monetization across its social media platforms, announced significant cost reductions, and paid its first dividend. What detracted from performance? An overweight allocation to the new industries subsector detracted. Among individual positions, an overweight in the semiconductor stock Wolfspeed, Inc.—which was hurt by weakness in the electric vehicle market—was the largest detractor. An overweight position in Adyen NV also hurt results. The Dutch financial-technology company faced subdued demand as price-sensitive customers migrated to lower-cost competitors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equity market sentiment was supported as fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. Within the growth stock universe, performance was led by a handful of mega-cap technology companies viewed as the likely principal beneficiaries of efforts to commercialize the use of artificial intelligence. What contributed to performance? Positive contributions to performance, relative to the benchmark (Russell 2500 TM What detracted from performance? The largest detractors from relative performance included stock selection in consumer discretionary, information technology and consumer staples. Within consumer discretionary, an overweight to the hotels, restaurants and leisure industry, specifically an overweight position in Vail Resorts, detracted from relative returns. Next, within information technology, lack of exposure to the technology hardware, storage and peripherals sub-sector weighed most heavily on performance. Lastly, selection in consumer staples, most notably an out-of-benchmark position in Davide Campari Milano within the beverages sub-sector, detracted from relative performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? U.S. equities broadly moved higher as the period progressed, resulting in significant positive returns across most market segments. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates, leading growth-oriented stocks to outperform value stocks. What contributed to performance? Positive contributions to the Fund’s performance relative to the benchmark (Russell 1000 ® What detracted from performance? The Fund’s overweight to and security selection with the healthcare sector detracted the most, with positioning in the healthcare equipment and supplies industry weighing most heavily on performance. Security selection within consumer staples also detracted from performance, particularly within the distribution and retail industry. Approximately 30% of the Fund is overwritten using a covered call strategy designed to provide a consistent stream of income. The use of covered calls detracted from performance as expected during a rising market environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Energy stocks delivered robust returns, albeit with elevated volatility, thanks to gains in both crude oil prices and the equity market more broadly. What contributed to performance? A zero weighting in Woodside Energy Group, Ltd. Contributed to performance, as did an underweight in Chevron Corp. An overweight in the midstream distribution company Williams Cos. also contributed to relative performance given its significant exposure to natural gas pipelines. What detracted from performance? The Fund held no positions in the refining company Phillips66, which rallied due to moves from an activist investor, which detracted from performance. A zero weighting in the Canadian integrated oil company Suncor Energy, Inc. detracted, as the stock rose on the strength of higher oil prices. Lack of positions in the Canadian uranium producer Cameco Corp., was an additional detractor, as the United States’ ban on Russia uranium imports was seen as a positive for the company.

The largest detractors from relative performance were certain fundamental insights including defensive quality measures that prefer balance sheet strength and more stable companies.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. What contributed to performance? Positive contributions to performance, relative to the benchmark (MSCI EAFE Index) were led by sentiment measures that were able to identify dominant trends by looking at informed investor positioning and through text-based analysis of broker reports (or conference calls). These insights correctly positioned the portfolio around Japanese stocks within financials and industrials that benefited as the theme of corporate reform continued to materialize in the region. Traditional fundamental measures also were additive, notably by driving positioning in U.K. consumer staples companies. An insight looking at research and development spending correctly positioned the portfolio in European healthcare stocks that benefited from enthusiasm around the use of GLP-1 drugs for weight loss. Finally, traditional quality insights looking at external financing correctly positioned the portfolio within information technology, particularly with respect to Japanese semiconductor companies likely to benefit from the emerging artificial intelligence theme. What detracted from performance? The largest detractors from relative performance included certain non-traditional fundamental quality insights, most notably those related to human capital such as those looking at veteran hiring, employee sentiment and hiring for environmental roles. In addition, changing market leadership proved a headwind to trend-following industry insights, with industry measures picking up on price momentum and favoring defensive positioning among the biggest laggards.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Commodities produced a strong, broad-based gain during the reporting period, reflecting positive supply-and-demand trends. Natural resource stocks delivered robust returns, albeit with elevated volatility, thanks to the gains in both commodity prices and the equity market more broadly. What contributed to performance? The Fund invested in both commodity derivatives and natural resources equities, with a weighting of approximately 50% in each. Positions in energy stocks delivered the most meaningful outperformance, as the Fund’s holdings in some of the larger integrated energy companies benefitted from robust oil prices. The Fund’s holdings in precious metals (both commodity-linked derivatives and mining companies) also delivered strong relative returns. The gold price increased approximately 20% over the period, driven by strong investment demand and plateauing interest rates. The Fund’s cash position had no material impact on performance. What detracted from performance? The Fund’s holdings in agriculture stocks detracted. While grain prices were relatively rangebound, companies with exposure to the onshore China market came under pressure.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equity market sentiment was supported as fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. Within the growth stock universe, performance was led by a handful of mega-cap technology companies viewed as the likely principal beneficiaries of efforts to commercialize the use of artificial intelligence. What contributed to performance? Positive contributions to the Fund’s performance relative to the benchmark (Russell Midcap ® What detracted from performance? The largest detractors from relative performance included stock selection in consumer discretionary and real estate, as well as positioning in energy. Within consumer discretionary, an out-of-benchmark benchmark position in Swedish online gaming solutions provider Evolution within the hotels, restaurants and leisure sub-sector weighed most heavily on returns. An overweight position to CoStar Group within real estate management and development was the biggest detractor. Lastly, an underweight to the energy sector, most notably to the oil, gas and consumable fuels sub-sector, detracted from relative performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Technology stocks, particularly those expected to benefit from the growing use of artificial intelligence, strongly outpaced the broader equity market. What contributed to performance? At the sub-sector level, an underweight allocation to hardware stocks contributed to results. On a stock-specific basis, an underweight position in Apple, Inc., which lagged due in part to increased competition in China, was the top contributor to performance. An off-benchmark position in Meta Platforms, Inc. was another leading contributor. The internet company reported artificial intelligence-driven improvements in monetization across its social media platforms, announced significant cost reductions, and paid its first dividend. What detracted from performance? An overweight allocation to the new industries subsector detracted. Among individual positions, an overweight in the semiconductor stock Wolfspeed, Inc.—which was hurt by weakness in the electric vehicle market—was the largest detractor. An overweight position in Adyen NV also hurt results. The Dutch financial-technology company faced subdued demand as price-sensitive customers migrated to lower-cost competitors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? International equities broadly moved higher as the period progressed, resulting in significant positive returns across most market segments. Major overseas economies returned to positive growth, supporting the corporate earnings outlook. Signs of easing inflation led to expectations that leading central banks were poised to begin reducing interest rates, leading growth-oriented stocks to outperform dividend payers. What contributed to performance? Positive contributions to performance, relative to the benchmark (MSCI ACWI ex USA Index) were led by stock selection in information technology, industrials and materials. In terms of individual holdings, Danish pharmaceutical company Novo Nordisk benefited from increased demand for its diabetes and obesity products, including Wegovy which is increasingly available outside the United States. ASML, the Dutch manufacturer of silicon photolithography systems used in semiconductor manufacturing, reported revenues and earnings that exceeded expectations, driven by record order growth. Results for British arms, security and aerospace company BAE Systems have been boosted by conflicts in Ukraine and the Middle East as governments bolster their military capabilities. What detracted from performance? The largest detractors from performance included stock selection within and underweights to financials and consumer staples. With respect to specific holdings, Swiss pharmaceutical and biotech company Lonza Biologics experienced the unexpected departure of its CEO and downgraded 2024 guidance at its Capital Markets Day. The downgrade was centered on the biologics division which management had previously indicated was fully booked for the foreseeable future, and the Fund exited the position. U.K.-based multinational insurance company Prudential Financial came under pressure due to weaker sentiment around China. Bank Rakyat, the Indonesian bank that specializes in small scale and microfinance lending, indicated that inconsistent underwriting practices (since rectified) in its rural loan program would likely lead to increased credit losses in coming months.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Equities produced strong performance behind resilient economic data, steady corporate earnings, and expectations that the U.S. Federal Reserve would begin to cut interest rates later in the year. Healthcare stocks, while producing a strong absolute return, did not keep pace with the broader market at a time in which technology stocks played the largest role in the performance of the major indexes. What contributed to performance? At the sub-sector level, security selection in pharmaceuticals contributed to results. On a stock-specific basis, an underweight position in Bristol Myers Squibb Co. was the top contributor to performance. The biopharmaceutical company missed sales expectations for select treatments and faced elevated competition from generic drugs. An overweight position in Boston Scientific Corp. was another leading contributor. The medical device company reported robust sales growth in its surgery and cardiovascular segments and received approval for a new treatment from the Food and Drug Administration. What detracted from performance? Selection in the biotechnology sub-sector detracted. Among individual positions, an overweight in the biotechnology stock Biogen, Inc.—which was hurt by slower-than-expected sales for its Alzheimer’s treatment Leqembi—was the largest detractor. An overweight position in Penumbra, Inc. also hurt results. The medical device company missed first-quarter earnings estimates due to a decline in its international sales.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. What contributed to performance? Positive contributions to performance, relative to the benchmark (MSCI EAFE Index) were led by sentiment measures that were able to identify dominant trends by looking at informed investor positioning and through text-based analysis of broker reports (or conference calls). These insights correctly positioned the portfolio around Japanese stocks within financials and industrials that benefited as the theme of corporate reform continued to materialize in the region. Traditional fundamental measures also were additive, notably by driving positioning in U.K. consumer staples companies. An insight looking at research and development spending correctly positioned the portfolio in European healthcare stocks that benefited from enthusiasm around the use of GLP-1 drugs for weight loss. Finally, traditional quality insights looking at external financing correctly positioned the portfolio within information technology, particularly with respect to Japanese semiconductor companies likely to benefit from the emerging artificial intelligence theme. What detracted from performance? The largest detractors from relative performance included certain non-traditional fundamental quality insights, most notably those related to human capital such as those looking at veteran hiring, employee sentiment and hiring for environmental roles. In addition, changing market leadership proved a headwind to trend-following industry insights, with industry measures picking up on price momentum and favoring defensive positioning among the biggest laggards.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Commodities produced a strong, broad-based gain during the reporting period, reflecting positive supply-and-demand trends. Natural resource stocks delivered robust returns, albeit with elevated volatility, thanks to the gains in both commodity prices and the equity market more broadly. What contributed to performance? The Fund invested in both commodity derivatives and natural resources equities, with a weighting of approximately 50% in each. Positions in energy stocks delivered the most meaningful outperformance, as the Fund’s holdings in some of the larger integrated energy companies benefitted from robust oil prices. The Fund’s holdings in precious metals (both commodity-linked derivatives and mining companies) also delivered strong relative returns. The gold price increased approximately 20% over the period, driven by strong investment demand and plateauing interest rates. The Fund’s cash position had no material impact on performance. What detracted from performance? The Fund’s holdings in agriculture stocks detracted. While grain prices were relatively rangebound, companies with exposure to the onshore China market came under pressure.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global equities enjoyed strong performance as resilient macro and micro data combined with excitement around the dominant themes of innovation in information technology and healthcare drove gains. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates. What contributed to performance? The Fund’s performance was driven by fundamental stock selection. Long positions in Nvidia Corp. and Amazon.com, Inc. proved beneficial amid the broader excitement around artificial intelligence. Elsewhere, long positions in energy companies Conocophillips Company and Suncor Energy Inc. also contributed positively. Gains from fundamental stock selection were compounded by systematic insights. Sentiment-based measures evaluating trends across analyst and executive comments as well as macro thematic insights measuring hiring trends and business-to-business invoicing collectively were key performance drivers. These insights broadly helped the Fund identify the dominant trends of what became an increasingly trending market. Finally, the Fund used derivatives to implement market timing models expressed in futures. These instruments contributed slightly to performance. The Fund’s cash position had no material impact on performance. What detracted from performance? While fundamental stock selection contributed in aggregate, select positions detracted from performance, including a net long to media company Comcast and a short to oil stock CNX Resources Corp. Elsewhere, systematic measures evaluating traditional financial statement data such as cash flows, valuations and dividend consistency ran against the prevailing market themes. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.
