Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the Russell 1000^® Growth Index was determined primarily by security selection, with sector allocation a secondary factor. Security selection within information technology detracted most, while selection within communication services contributed positively.

The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Portfolio’s performance during the reporting period.

Key Factor	Summary	Impact
Communication services	Security selection and an overweight position	Contributed
Consumer staples	Lack of exposure	Contributed
Real estate	Security selection	Contributed
Information technology	Security selection and an underweight position	Detracted
Financials	Security selection and an overweight position	Detracted
Consumer discretionary	Security selection	Detracted

Line Graph [Table Text Block]

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. Effective July 29, 2016, the Portfolio's principal investment strategies were modified in connection with changes to the Portfolio's subadvisor. The past performance in the graph and table prior to that date reflects the Portfolio's prior subadvisor and principal investment strategies. The Portfolio’s subadvisor changed effective January 1, 2018, due to an organizational restructuring whereby all investment personnel of Cornerstone Capital Management Holdings LLC, the former subadvisor, transitioned to MacKay Shields LLC. Effective May 1, 2021, the Portfolio replaced its subadvisor and modified its principal investment strategies. The past performance prior to these dates reflect the Portfolio's subadvisor and principal investment strategies.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the ICE BofA U.S. Convertible Index was negatively affected by lack of exposure to two securities in the industrials sectors (Bloom Energy and Rocket Lab), as well as by overweight exposure to the health care sector. Conversely, relative performance benefited from security selection in the utilities and technology sectors.

Key Factor	Summary	Impact
NRG Energy	Benefited from growing demand for electric power for computer processors linked to Artificial Intelligence ("AI")	Contributed
Seagate Technology Holdings	Benefited from expectations of increased demand for the company’s hard disk drives from AI-focused data centers	Contributed
Mirum Pharmaceuticals	Benefited from better-than-expected sales and significantly increased guidance	Contributed
Bloom Energy	Lack of exposure to a beneficiary of the rush to build AI data centers	Detracted
Rocket Lab	Lack of exposure to a company experiencing strong demand for its satellite launch services and its new heavier rocket program	Detracted
Integer Holdings	Exposure to a medical device manufacturer that reported slightly better-than-expected quarterly results but lowered expectations for the fourth quarter and the first half of 2026	Detracted

1.	The Portfolio has selected the Bloomberg U.S. Aggregate Bond Index to represent a broad measure of market performance. The Bloomberg U.S. Aggregate Bond Index is a broad-based benchmark that measures the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable rate mortgage pass-throughs), asset-backed securities and commercial mortgage-backed securities.
2.	The ICE BofA U.S. Convertible Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, is a market-capitalization weighted index of domestic corporate convertible securities. In order to be included in the ICE BofA U.S. Convertible Index, bonds and preferred stocks must be convertible only to common stock.
3.	The Morningstar Convertibles Category Average is representative of funds that are designed to offer some of the capital-appreciation potential of stock portfolios while also supplying some of the safety and yield of bond portfolios. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

1.	The Portfolio has selected the Bloomberg U.S. Aggregate Bond Index to represent a broad measure of market performance. The Bloomberg U.S. Aggregate Bond Index is a broad-based benchmark that measures the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable rate mortgage pass-throughs), asset-backed securities and commercial mortgage-backed securities.
2.	The ICE BofA U.S. Convertible Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, is a market-capitalization weighted index of domestic corporate convertible securities. In order to be included in the ICE BofA U.S. Convertible Index, bonds and preferred stocks must be convertible only to common stock.
3.	The Morningstar Convertibles Category Average is representative of funds that are designed to offer some of the capital-appreciation potential of stock portfolios while also supplying some of the safety and yield of bond portfolios. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the Russell 1000^® Value Index was determined primarily by security selection. From a factor perspective, the Fund’s negative exposure to market sensitivity detracted from relative performance.

Key Factor	Summary	Impact
Health care	Security selection, driven by overweight exposure to CVS Health Corp. and AbbVie Inc.	Contributed
Consumer staples	Security selection, driven by overweight exposure to Philip Morris International Inc.	Contributed
Communication services	Security selection, driven by underweight exposure to Alphabet Inc.	Detracted
Industrials	Security selection, driven by lack of exposure to GE Aerospace and Caterpillar Inc.	Detracted

1.	The Portfolio has selected the Russell 3000^® Index to represent a broad measure of market performance. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies representing approximately 98% of the investable U.S. equity market.
2.	The Russell 1000^® Value Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, measures the performance of the large-cap value segment of the U.S. equity universe. It includes those Russell 1000^® Index companies with lower price-to-book ratios and lower expected growth values.
3.	The U.S. Equity Yield Composite Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, consists of the MSCI USA High Dividend Yield Index and the MSCI USA Minimum Volatility (USD) Index weighted at 60% and 40%, respectively. The MSCI USA High Dividend Yield Index is based on the MSCI USA Index and includes large- and mid-cap stocks. It is designed to reflect the performance of equities in the MSCI USA Index (excluding real estate investment trusts) with higher dividend income and quality characteristics than average dividend yields that are both sustainable and persistent. The MSCI USA Minimum Volatility (USD) Index aims to reflect the performance characteristics of a minimum variance strategy applied to the large- and mid-cap U.S. equity universe. The MSCI USA Minimum Volatility (USD) Index is calculated by optimizing the MSCI USA Index in U.S. dollars for the lowest absolute risk (within a given set of constraints).
4.	The Morningstar Large Value Category Average is representative of funds that invest primarily in big U.S. companies that are less expensive or growing more slowly than other large-cap stocks. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the Russell 1000^® Growth Index was driven by both security selection and sector allocation.

Key detractors included positioning in health care, consumer discretionary and financials, as well as security selection in information technology, financials and communication services.

Key Factor	Summary	Impact
Industrials	Overweight exposure and strong security selection	Contributed
Consumer staples	Lack of exposure to an underperforming sector	Contributed
Energy	Lack of exposure to an underperforming sector	Contributed
Information technology	Underweight exposure and weak security selection	Detracted

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, U.S. equity markets delivered uneven results, with shifting leadership and elevated dispersion creating a challenging environment for active managers during much of the year. The Portfolio’s performance relative to the Russell Midcap^® Index was supported, particularly during the fourth quarter, by effective stock selection in information technology and health care as market leadership shifted toward higher-quality companies. Earlier in the year, relative returns were pressured by sector allocation and stock selection in information technology, financials and health care, partly offset by contributions from industrials and real estate.

Key Factor	Summary	Impact
Information technology	Stock selection in technology hardware and overweight exposure to communications equipment	Contributed
Ciena Corp.	Benefited from impressive growth in Cloud and firmly re-established its position from a telco supplier to a leading Artificial Intelligence infrastructure company	Contributed
Industrials	Stock selection in machinery and electrical equipment overshadowed positive sector allocation in aerospace & defense	Detracted
Financials	Stock selection in capital markets and insurance	Detracted
Zebra Technologies Corp.	Negatively affected by global uncertainty and conservative guidance in the second half of 2025	Detracted

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. The Portfolio’s subadvisor changed effective January 1, 2018 due to an organizational restructuring whereby all investment personnel of Cornerstone Capital Management Holdings LLC, the former subadvisor, transitioned to MacKay Shields LLC. Effective May 1, 2021, the Portfolio replaced its subadvisor and modified its principal investment strategies. Effective August 12, 2024, the Portfolio again replaced its subadvisor and modified its principal investment strategies. The past performance in the graph and table prior to that date reflects the Portfolio’s prior subadvisors and principal investment strategies.

2.	The Russell Midcap^® Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, measures the performance of the mid-cap segment of the U.S. equity universe. The Russell Midcap^® Index is a subset of the Russell 1000^® Index and includes approximately 800 of the smallest companies based on a combination of their market cap and current index membership. The Russell Midcap^® Index represents approximately 27% of the total market capitalization of the Russell 1000^® Index companies.
3.	The S&P MidCap 400^® Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, is a market capitalization-weighted index of common stocks representing the mid-cap U.S. equity market.
4.	The Morningstar Mid-Cap Blend Category Average is representative of funds that invest primarily in U.S. stocks of various sizes and styles, giving it a middle-of-the-road profile. The U.S. mid-cap range for market capitalization typically falls between $1 billion and $8 billion and represents 20% of the total capitalization of the U.S. equity market. The blend style is assigned to funds where neither growth nor value characteristics predominate. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the Russell 1000^® Index benefited from lack of exposure to the underperforming real estate investment trust sector. However, the Portfolio’s focus on high profitability stocks detracted from relative performance, as did its emphasis on mid-cap stocks.

Key Factor	Summary	Impact
Real estate investment trusts (REITs)	Lack of exposure to an underperforming sector	Contributed
Profitability	Overweight exposure to large-cap stocks in the highest 35% of market capitalization by profitability	Detracted
Size	Overweight exposure to mid-cap stocks	Detracted

1.	The Portfolio has selected the Russell 3000^® Index to represent a broad measure of market performance. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies representing approximately 98% of the investable U.S. equity market.
2.	The Russell 1000^® Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, measures the performance of the large-cap segment of the U.S. equity universe. It is a subset of the Russell 3000^® Index and includes approximately 1,000 of the largest securities based on a combination of their market cap and current index membership.
3.	The S&P 500^® Index is generally representative of the market sectors or types of investments in which the Portfolio invests. S&P^® and S&P 500^® are registered trademarks of Standard & Poor’s Financial Services LLC.

4.	The Morningstar Large Blend Category Average is representative of funds that represent the overall U.S. stock market in size, growth rates and price. Stocks in the top 70% of the capitalization of the U.S. equity market are defined as large cap. The blend style is assigned to funds where neither growth nor value characteristics predominate. These funds tend to invest across the spectrum of U.S. industries, and owing to their broad exposure, the funds' returns are often similar to those of the S&P 500^® Index. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

Relative to the Russell 1000^® Value Index and the Bloomberg U.S. Intermediate Government/Credit Bond Index, the Portfolio’s performance during the 12-month period ended December 31, 2025, was affected primarily by sector allocation on both the equity and fixed income sides. Among equities, in addition to the factors detailed in the table below, security selection also had a material impact on relative returns, either positive (health care, communication services and industrials) or negative (financials, consumer discretionary and materials). In fixed income, in addition to the factors detailed in the table below, the Portfolio also benefited from overweight exposure to specific subcomponents of the commercial mortgage-backed securities sector and from relatively long duration positioning in one instance during the second half of the reporting period.

Key Factor	Summary	Impact
	Equities
Consumer staples	Underweight allocation	Contributed
Real estate	Underweight allocation	Contributed
Communication services	Underweight allocation	Detracted
Health care	Overweight allocation	Detracted
	Fixed Income
Mortgage-backed securities	Overweight positions in both the agency and non-agency subcomponents	Contributed
Asset-backed securities (ABS)	An overweight position in the AAA-rated collateralized loan obligation subcomponent of the floating-rate portion of the ABS sector	Contributed
U.S. Treasury sector	Underweight allocation	Detracted
Cash securities	Overweight allocation	Detracted

Performance Past Does Not Indicate Future [Text]

Keep in mind that the Portfolio ’s past performance is not a good predictor of how the Portfolio will perform in the future.

Line Graph [Table Text Block]

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. The Portfolio's equity subadvisor changed effective January 1, 2018 due to an organizational restructuring whereby all investment personnel of Cornerstone Capital Management Holdings LLC, the former subadvisor, transitioned to MacKay Shields LLC. Effective May 1, 2021, the Portfolio replaced the subadvisor to the equity portion of the Portfolio and modified the equity portion of the Portfolio's principal investment strategies. The past performance in the graph and table prior to that date reflects the Portfolio's prior subadvisor and principal investment strategies for the equity portion of the Portfolio.

3.	The Bloomberg U.S. Intermediate Government/Credit Bond Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, measures the performance of U.S. dollar-denominated U.S. treasuries, government-related and investment grade U.S. corporate securities that have a remaining maturity of greater than one year and less than ten years.
4.	The Balanced Composite Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, consists of the Russell 1000^® Value Index and the Bloomberg U.S. Intermediate Government/Credit Bond Index weighted 60%/40%, respectively.
5.	The Morningstar Moderate Allocation Category Average is representative of funds in allocation categories that seek to provide both income and capital appreciation by primarily investing in multiple asset classes, including stocks, bonds, and cash. These moderate strategies seek to balance preservation of capital with appreciation. They typically expect volatility similar to a strategic equity exposure between 50% and 70%.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

The Portfolio’s performance relative to the Morningstar LSTA US Leveraged Loan Index during the 12-month reporting period ended December 31, 2025, was determined by positioning across various industries and credit ratings. The strongest contributions to relative performance came from overweight positions in out-of-Index holdings, chemicals, and hotels, restaurants & leisure holdings, as well as overweight exposure to credit rated B. The underweight position in credit rated CCC was the primary detractor.

Key Factor	Summary	Impact
N/A SNP industry	Primarily collateralized loan obligation tranches and some high yield bonds, representing out-of-Index positions	Contributed
Chemicals	Overweight positioning, positive security selection	Contributed
Hotels, restaurants & leisure	Overweight positioning, positive security selection	Contributed
Auto components	Overweight positioning, negative security selection	Detracted
Specialty retail	Underweight positioning, negative security selection	Detracted
Insurance	Underweight positioning, positive security selection	Detracted

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, strong returns in capital markets drove impressive Portfolio gains in absolute terms. Relative to its benchmark indices and to the internally maintained blend of indices that are taken into consideration when managing the Portfolio, the Portfolio’s performance benefited from a modest allocation to convertible bonds and an active weight in select emerging markets. However, most other positions detracted, primarily due to the underperformance of several underlying fund investments, as well the Portfolio’s tilt toward profitable mid- and small-cap companies.

Key Factor	Summary	Impact
Convertible bonds	Benefited from strong performance in growth equities	Contributed
Emerging markets	Exposure to a vehicle that explicitly avoids Chinese holdings	Contributed
Underlying funds	In aggregate, underlying fund holdings underperformed their respective benchmarks	Detracted
Small-cap profitability tilt	Focused on profitable small-cap companies in a period when profitless but potentially fast-growing small-caps outperformed	Detracted
Small-/mid-cap tilt	Focused on assets down the capitalization spectrum in anticipation of continued monetary policy easing	Detracted
U.S.-centric focus	Favored U.S. equities over other developed markets as a play on the administration’s “America First” agenda	Detracted

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, strong returns in capital markets drove impressive Portfolio gains in absolute terms. Relative to its benchmark indices and to the internally maintained blend of indices that are taken into consideration when managing the Portfolio, the Portfolio’s performance benefited from an active weight in select emerging markets. However, most other positions detracted, primarily due to the underperformance of several underlying fund investments, as well the Portfolio’s tilt toward profitable mid- and small-cap companies.

Key Factor	Summary	Impact
Emerging markets	Exposure to a vehicle that explicitly avoids Chinese holdings	Contributed
Underlying funds	In aggregate, underlying fund holdings underperformed their respective benchmarks	Detracted
Small-cap profitability tilt	Focused on profitable small-cap companies in a period when profitless but potentially fast-growing small-caps outperformed	Detracted
Small-/mid-cap tilt	Focused on assets down the capitalization spectrum in anticipation of continued monetary policy easing	Detracted
U.S.-centric focus	Favored U.S. equities over other developed markets as a play on the administration’s “America First” agenda	Detracted
Nuclear energy industry	First-quarter exposure, pressured by tariff concerns and AI-efficiency developments	Detracted

1.	The Portfolio has selected the Russell 3000^® Index to represent a broad measure of market performance. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies representing approximately 98% of the investable U.S. equity market.
2.	The S&P 500^® Index, which represents a broad measure of market performance, is generally representative of the market sectors or types of investments in which the Portfolio invests. S&P^® and S&P 500^® are registered trademarks of Standard & Poor’s Financial Services LLC. The S&P 500^® Index is widely regarded as the standard index for measuring large-cap U.S. stock market performance.

5.	The Morningstar Aggressive Allocation Category Average is representative of funds in allocation categories that seek to provide both income and capital appreciation by primarily investing in multiple asset classes, including stocks, bonds, and cash. These aggressive strategies typically allocate at least 10% to equities of foreign companies and prioritize capital appreciation over preservation. They typically expect volatility similar to a strategic equity exposure of more than 85%. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

Although the Portfolio seeks investment results that correspond to the total return performance of common stocks in the aggregate, as represented by the S&P 500^® Index, the Portfolio’s relative performance will typically lag that of the Index because the Portfolio incurs operating expenses that the Index does not.

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. The Portfolio’s subadvisor changed effective January 1, 2018 due to an organizational restructuring whereby all investment personnel of Cornerstone Capital Management Holdings LLC, the former subadvisor, transitioned to MacKay Shields LLC. The Portfolio's subadvisor changed again effective June 10, 2022 due to the transition of Francis J. Ok, the Portfolio's portfolio manager, from MacKay Shields LLC, a former subadvisor, to IndexIQ Advisors LLC, which is a wholly-owned, indirect subsidiary of New York Life Investment Holdings LLC. Effective August 28, 2024, all investment personnel of IndexIQ Advisors LLC, a former subadvisor, and the day-to-day investment services provided by IndexIQ Advisors LLC to the Portfolio, were transitioned to New York Life Investment Management LLC.

The Portfolio has selected the S&P 500^® Index, which represents a broad measure of market performance, and is generally representative of the market sectors or types of investments in which the Portfolio invests. The S&P 500^® Index is widely regarded as the standard index for measuring large-cap U.S. stock market performance. S&P^® and S&P 500^® are registered trademarks of Standard & Poor’s Financial Services LLC (“S&P”) and Dow Jones^® is a registered trademark of Dow Jones Trademark Holdings LLC (“Dow Jones”).

The Morningstar Large Blend Category Average is representative of funds that represent the overall U.S. stock market in size, growth rates and price. Stocks in the top 70% of the capitalization of the U.S. equity market are defined as large cap. The blend style is assigned to funds where neither growth nor value characteristics predominate. These funds tend to invest across the spectrum of U.S. industries, and owing to their broad exposure, the funds' returns are often similar to those of the S&P 500^® Index. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month period ended December 31, 2025, the Portfolio’s performance relative to the MSCI World Index (Net) and the Bloomberg U.S. Aggregate Bond Index was affected primarily by security selection on the equity side and by sector allocation on the fixed income side. Among equities, industry exposures as well as positive exposure to dividend yield supported performance. Among fixed income positions, returns benefited from a healthy debt capital market supported by a resilient U.S. economy, falling interest rates and tightening risk premiums, as well as broad diversification across interest rate, credit and structure risk, along with a curve-flattening bias and overweight exposure to mortgage and consumer credit.

Key Factor	Summary	Impact
	Equities
Health care	Security selection, driven by overweight exposure to CVS	Contributed
Information technology	Security selection, driven by overweight exposure to Samsung, Taiwan Semiconductor Manufacturing and KLA	Contributed
Communication services	Security selection, driven by underweight exposure to Alphabet	Detracted
Materials	Security selection, driven by overweight exposure to LyondellBasell Industries	Detracted
	Fixed Income
Non-agency mortgage credit	Overweight exposure to commercial mortgage obligations and seasoned credit risk transfers on valuations	Contributed
Non-agency commercial mortgage-backed securities	Overweight exposure to select SASB (single asset single borrower) and conduits with diversified property collateral	Contributed
Agency mortgage-backed securities	Underweight exposure to the basis (overweight higher coupon, underweight lower coupon)	Detracted
Investment-grade corporates	Underweight exposure to the sector, but overweight financials and utilities	Detracted

1.	The Portfolio has selected the MSCI World Index (Net), which represents a broad measure of market performance, and is generally representative of the market sectors or types of investments in which the Portfolio invests. The MSCI World Index (Net) is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets.
2.	The Bloomberg U.S. Aggregate Bond Index is a broad-based benchmark that measures performance of the investment-grade, U.S. dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable-rate mortgage pass-throughs), asset-backed securities and commercial mortgage-backed securities.
3.	The Blended Benchmark Index is comprised of the MSCI World Index (Net) and the Bloomberg U.S. Aggregate Bond Index weighted 60%/40%, respectively.
4.	Morningstar Global Moderate Allocation Category Average funds seek to provide both income and capital appreciation by primarily investing in multiple asset classes, including stocks, bonds, and cash. These moderate strategies seek to balance preservation of capital with appreciation. They typically expect volatility similar to a strategic equity exposure between 50% and 70%.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, interest rates moved lower, and the curve steepened. The two-year part of the curve moved 77 basis points (“bps”) lower while the ten-year part of the curve moved 40 bps lower. Within the Portfolio’s benchmark, the Bloomberg U.S. Aggregate Bond Index, mortgage-backed securities (“MBS”) was the best performing sector, producing 171 bps of excess return, while high-grade credit produced 126 bps of excess return, outperforming both commercial mortgage-backed securities (“CMBS”) (103 bps) and asset-backed securities (“ABS”) (55 bps).

Key Factor	Summary	Impact
MBS	Security selection, particularly within the agency commercial mortgage obligation subcomponent	Contributed
ABS	Within the floating-rate portion of the ABS sector, overweight exposure to the AAA and AA collateralized loan obligation subcomponent; within the fixed-rate portion of the sector, overweight positions in the digital infrastructure and student loan subcomponents	Contributed
CMBS	Overweight positions in both the agency and non-agency subcomponents	Contributed
Corporate sector	Overweight exposure to industrials, particularly the technology and communication subcomponents	Detracted
Treasury sector	Underweight exposure	Detracted
Duration + curve	Maintained a duration relatively close to that of the Index	Detracted

The Portfolio has selected the Bloomberg U.S. Aggregate Bond Index, which represents a broad measure of market performance, and is generally representative of the market sectors or types of investments in which the Portfolio invests. The Bloomberg U.S. Aggregate Bond Index is a broad-based benchmark that measures the performance of the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable rate mortgage pass-throughs), asset-backed securities and commercial mortgage-backed securities.

The Morningstar Intermediate Core Bond Category Average is representative of funds that invest primarily in investment-grade U.S. fixed-income issues including government, corporate, and securitized debt, and hold less than 5% in below-investment-grade exposures. Their durations (a measure of interest-rate sensitivity) typically range between 75% and 125% of the three-year average of the effective duration of the Morningstar Core Bond Index. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

2.	The Bloomberg 5-10 Year Taxable Municipal Bond Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, is the 5-10 year component of the Bloomberg Taxable Municipal Bond Index.
3.	The Morningstar Intermediate Core Bond Category Average is representative of funds that invest primarily in investment-grade U.S. fixed-income issues including government, corporate, and securitized debt, and hold less than 5% in below-investment-grade exposures. Their durations (a measure of interest-rate sensitivity) typically range between 75% and 125% of the three-year average of the effective duration of the Morningstar Core Bond Index. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, interest rates in the front end of the curve moved lower as the U.S. Federal Reserve cut interest rates by 75 basis points. The 1-month part of the curve moved 68 basis points lower while the six-month part of the curve moved 66 basis points lower. Performance relative to the Average Lipper Variable Products U.S. Government Money Market Portfolio was affected by positions in asset classes not included in the benchmark, including U.S. agency discount notes and tri-party repo, which the Portfolio offset by maintaining an underweight position in the Treasury Bill sector.

Key Factor	Summary	Impact
Treasury bills	Underweight exposure	Contributed
U.S. agency discount notes	Overweight positions in Federal Agricultural Mortgage Corp. and Federal Farm Credit Banks Funding Corp.	Contributed
Tri-party repo	Overweight position in the tri-party repo sector, including Royal Bank of Canada, Toronto-Dominion Bank, Bank of America Securities, Bank of Montreal and Bank of Nova Scotia	Contributed
Duration + curve	Maintained a duration slightly shorter than that of the Index	Detracted

Performance Past Does Not Indicate Future [Text]

Keep in mind that the Portfolio ’s past performance is not a good predictor of how the Portfolio will perform in the future.

Line Graph [Table Text Block]

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. Effective August 26, 2016 and October 14, 2016, the Portfolio modified its principal investment strategies in connection with commencing operations as a “government money market fund.” Consequently the performance information below may have been different if the current investment strategies had been in effect during the period prior to the Portfolio commencing operations as a “government money market fund.” For certain periods, the Manager voluntarily has waived or reimbursed the Portfolio’s expenses to the extent it deemed appropriate to enhance the Portfolio's yield during periods when expenses had a significant impact on yield because of low interest rates. Without these waivers or reimbursements, the Portfolio’s returns would have been lower.

Average Lipper Variable Products U.S. Government Money Market Portfolio¹		3.89%	2.91%	1.83%
Morningstar Prime Money Market Category Average²		3.98%	3.01%	1.98%

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the ICE BofA U.S. High Yield Constrained Index was affected by security selection and sector allocation. Other than a brief period around the Liberation Day comments on tariffs at the beginning of the second quarter, when spreads widened and issuance dried up, the high yield market was supported by high investor demand, strong issuance and lower yields driven by tighter spreads and lower Treasury rates. The fourth quarter of 2025 marked the thirteenth consecutive positive quarter for U.S. high yield, with $58.8 billion of new issuance in September 2025—the highest monthly volume since March 2021 and the third-highest monthly total on record.

Key Factor	Summary	Impact
Utilities	Credit selection, with Lightning Power a strong performer, plus lack of exposure to energy storage company Sunnova, which underperformed	Contributed
Capital goods	Credit selection and overweight exposure, plus lack of exposure to Ardagh Packaging, which underperformed	Contributed
Basic industry	Credit selection and overweight exposure, with Miner First Quantum Minerals a strong performer	Contributed
Telecommunications	Credit selection and underweight exposure, including a position in Liberty Media Puerto Rico, which underperformed, and underweight exposure to EchoStar, which outperformed	Detracted

The ICE BofA U.S. High Yield Constrained Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, is a market value-weighted index of all domestic and Yankee high-yield bonds, including deferred interest bonds and payment-in-kind securities. Issuers included in the ICE BofA U.S. High Yield Constrained Index have maturities of one year or more and have a credit rating lower than BBB-/Baa3, but are not in default. No single issuer may constitute greater than 2% of the ICE BofA U.S. High Yield Constrained Index.
3.	The Morningstar High Yield Bond Category Average is representative of funds that concentrate on lower-quality bonds, which are riskier than those of higher-quality companies. These funds primarily invest in U.S. high-income debt securities where at least 65% or more of bond assets are not rated or are rated by a major agency such as Standard & Poor’s or Moody’s at the level of BB and below. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the MSCI EAFE^® Index (Net) was determined primarily by stock selection and allocation effects. Positive contributions came from security selection in information technology and consumer discretionary. Primary detractors included security selection in financials, industrials and health care, along with underweight exposure to financials.

Key Factor	Summary	Impact
Information technology	Positive security selection	Contributed
Consumer discretionary	Positive security selection	Contributed
Financials	Negative security selection and underweight allocation	Detracted
Industrials	Negative security selection	Detracted
Health care	Negative security selection	Detracted

Line Graph [Table Text Block]

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. The Portfolio’s subadvisor changed effective January 1, 2018 due to an organizational restructuring whereby all investment personnel of Cornerstone Capital Management Holdings LLC, the former subadvisor, transitioned to MacKay Shields LLC. Effective August 28, 2023, the Portfolio replaced its subadvisor, changed its investment objective and modified its principal investment strategies. The past performance in the graph and table prior to that date reflects the Portfolio's prior subadvisor, investment objective and principal investment strategies.

The Portfolio has selected the MSCI EAFE® Index (Net) to represent a broad measure of market performance, and it is generally representative of the market sectors or types of investments in which the Portfolio invests. The MSCI EAFE® Index (Net) consists of international stocks representing the developed world outside of North America.

The Morningstar Foreign Large Growth Category Average is representative of funds that focus on high-priced growth stocks, mainly outside of the United States. Most of these funds divide their assets among a dozen or more developed markets, including Japan, Britain, France, and Germany. These funds primarily invest in stocks that have market caps in the top 70% of each economically integrated market and will have less than 20% of assets invested in U.S. stocks. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the Bloomberg U.S. Aggregate Bond Index benefited from a healthy debt capital market supported by a resilient U.S. economy, falling interest rates and tightening risk premiums. The Portfolio was broadly diversified across interest rate, credit and structure risk, producing a premium yield above the market at a discount dollar price. Further, the Portfolio’s curve-flattening bias added to results, as did overweight exposure to mortgage and consumer credit.

Key Factor	Summary	Impact
Non-agency mortgage credit	Overweight exposure to commercial mortgage obligations and seasoned credit risk transfers on valuations	Contributed
Non-agency commercial mortgage-backed securities	Overweight exposure to select SASB (single asset single borrower) and conduits with diversified property collateral	Contributed
Asset-backed securities	Overweight exposure to seasoned auto and whole business loans	Contributed
Emerging markets	Overweight exposure to select U.S.-dollar denominated corporates and sovereigns in stable countries with improving fundamentals	Contributed
Agency mortgage-backed securities	Underweight exposure to the basis (overweight higher coupon, underweight lower coupon)	Detracted
Investment-grade corporates	Underweight exposure to the sector, but overweight to financials and utilities	Detracted

The Portfolio has selected the Bloomberg U.S. Aggregate Bond Index to represent a broad measure of market performance, and is generally representative of the market sectors or types of investments in which the Portfolio invests. The Bloomberg U.S. Aggregate Bond Index is a broad-based benchmark that measures the performance of the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable-rate mortgage pass-throughs), asset-backed securities and commercial mortgage-backed securities.

The Morningstar Multisector Bond Category Average is representative of funds that seek income by diversifying their assets among several fixed-income sectors, usually U.S. government obligations, U.S. corporate bonds, foreign bonds, and high-yield U.S. debt securities. These portfolios typically hold 35% to 65% of bonds assets in securities that are not rated by a major agency such as Standard & Poor’s or Moody’s at the level of BB (considered speculative for taxable bonds) and below. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the MSCI Emerging Markets Index (Net) was affected by security selection and allocation. Artificial Intelligence ("AI")-related demand remained robust, which bolstered many technology companies. The price strength of precious and industrial metals boosted the materials sector.

Key Factor	Summary	Impact
South Korean technology	Supported by deep manufacturing expertise, rising utilization rates and increasing process intensity at advanced nodes	Contributed
Taiwanese technology	Rallied on robust AI-related demand (servers, chips, etc.) and better-than-expected results	Contributed
Materials	Benefited from sustained central-bank gold purchases and strong electrification-related demand for copper and lithium	Contributed
India	Weak earnings, in addition to high expectations and lingering geopolitical uncertainty	Detracted

Line Graph [Table Text Block]

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. One of the Portfolio's subadvisors changed effective January 1, 2018 due to an organizational restructuring whereby all investment personnel of Cornerstone Capital Management Holdings LLC, the former subadvisor, transitioned to MacKay Shields LLC. Effective May 1, 2021, the Portfolio replaced one of its subadvisors and modified its principal investment strategies. The past performance in the graph and table prior to that date reflects the Portfolio's prior subadvisors and principal investment strategies.

Morningstar Diversified Emerging Markets Category Average²		30.55%	4.29%	7.93%

The Portfolio has selected MSCI Emerging Markets Index (Net), which represents a broad measure of market performance, and is generally representative of the market sectors or types of investments in which the Portfolio invests. The MSCI Emerging Markets Index (Net) is a free float-adjusted market capitalization index that is designed to measure equity market performance in the global emerging markets.

The Morningstar Diversified Emerging Markets Category Average is representative of funds that tend to divide their assets among 20 or more nations, although they tend to focus on the emerging markets of Asia and Latin America rather than on those of the Middle East, Africa, or Europe. These funds invest predominantly in emerging market equities, but some funds also invest in both equities and fixed income investments from emerging markets. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, separate portions of the Portfolio were subadvised by Segall Bryant & Hamill, LLC (“SBH”) and Brown Advisory LLC (“Brown Advisory”). Relative to the Russell 2000^® Growth Index, the performance of the portion of the Portfolio subadvised by SBH was driven primarily by security selection, with sector allocation a secondary factor. The relative performance of the portion of the Portfolio subadvised by Brown Advisory was determined by a variety of factors, including a “risk-on” rally of lower quality companies, investor enthusiasm for companies related to artificial intelligence ("AI"), cryptocurrencies and quantum computing, and stock selection in the health care, information technology and consumer staples sectors.

Key Factor	Summary	Impact
	SBH
Communication services	Lack of exposure to an underperforming sector	Contributed
Information technology	Allocation and security selection, particularly in software and semiconductors	Contributed
Industrials	Security selection across a number of industries	Detracted
Health care	Underweight exposure to biotechnology and a position in surgical robotics company PROCEPT BioRobotics Corp.	Detracted
	Brown Advisory
Consumer staples	Security selection	Contributed
Low-quality “risk-on” rally	Underweight exposure to a group that rallied sharply late in the year	Detracted
AI/cryptocurrency/quantum computing	Underweight exposure to AI-, cryptocurrency- and quantum computing-related securities	Detracted
Health care	Security selection and underweight exposure to biotechnology and pharmaceuticals	Detracted

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the S&P Global Natural Resources Index was undermined by a contrarian overweight position in oil, based on expected U.S. shale declines and tighter supply. Tariff uncertainty and rising recession risks depressed oil prices and the Portfolio’s energy holdings, while underweight exposure to precious metals detracted as gold rallied on safe-haven demand amid geopolitical and macroeconomic tensions. We trimmed the Portfolio’s exposure to gold earlier, expecting the rate-cutting cycle to end, which left the strategy underexposed during the rally.

Key Factor	Summary	Impact
ArcelorMittal SA	Benefited from expectations of additional price protection measures for European steel	Contributed
GE Vernova, Inc.	Performed well after reporting results ahead of expectations, with robust new orders supporting higher forward estimates	Contributed
Freeport-McMoRan, Inc.	Benefited as copper prices rose	Contributed
Crescent Energy Co.	Underperformed peers, largely reflecting greater share-price volatility associated with the company’s smaller market capitalization	Detracted
International Paper Co.	Suffered as demand concerns fueled apprehension regarding forward guidance	Detracted
BP plc	Affected by lower oil prices and investor caution related to the company’s more leveraged balance sheet	Detracted

Performance Past Does Not Indicate Future [Text]

Line Graph [Table Text Block]

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. The Portfolio replaced its subadvisor, changed its investment objective and modified its principal investment strategies as of November 30, 2018. The past performance in the graph and table prior to that date reflects the Portfolio’s prior subadvisor, investment objective and principal investment strategies. The Portfolio's subadvisor changed effective September 1, 2021 due to an organizational restructuring whereby all investment personnel of Mellon Investments Corporation, the former subadvisor, transitioned to Newton Investment Management North America, LLC.

S&P Global Natural Resources Index²		29.66%	11.32%	11.09%
Morningstar Natural Resources Category Average³		39.14%	11.36%	11.05%

1.	The Portfolio has selected the MSCI World Index (Net), to represent a broad measure of market performance. The MSCI World Index (Net) is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets.
2.	The S&P Global Natural Resources Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, includes 90 of the largest publicly-traded companies in natural resources and commodities businesses that meet specific investability requirements, offering investors diversified and investable equity exposure to agribusiness, energy, and metals & mining.
3.	The Morningstar Natural Resources Category Average is representative of funds that invest primarily on commodity-based industries such as energy, chemicals, minerals, and forest products in the United States or outside of the United States. Some funds invest across this spectrum to offer broad natural-resources exposure. Others concentrate heavily or even exclusively in specific industries. Funds that concentrate primarily in energy-related industries are part of the equity energy category. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to its benchmark indices and to the Janus Balanced Composite Index was determined primarily by asset allocation positioning and security selection. Relative performance benefited most notably from overweight exposure to equities and corresponding underweight exposure to fixed income during a period in which equities outperformed bonds. Relative performance within the equity and fixed income asset classes further contributed to the Portfolio’s overall relative performance, although positioning in some equity and fixed income sectors detracted.

Key Factor	Summary	Impact
Equity sector positioning	Maintained overweight exposure to growthier sectors, which outperformed the broader market, and underweight exposure to lagging consumer staples and real estate sectors	Contributed
Stock selection	Benefited from security selection in financials, highlighted by investment bank and wealth management holdings; and in information technology, led by suppliers of wafer fabrication equipment	Contributed
Fixed income positioning	Benefited from several sector allocation and security selection decisions, including security selection in investment-grade corporates and overweight allocations to non-agency mortgages, commercial mortgage-backed securities and high-yield corporates	Contributed
Consumer discretionary	Overweight sector allocation and security selection, highlighted by a position in athletic footwear, apparel and accessory company Nike, Inc.	Detracted
Real estate	Negative stock selection, highlighted by a position in industrial REIT Prologis, Inc.	Detracted
Asset-backed securities	Security selection	Detracted

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the S&P 500^® Index was determined primarily by security selection. The strongest contributors to relative performance came from the communications services sector. The most significant detractors came from information technology, where lack of exposure to several Artificial Intelligence ("AI")-related names that helped drive the market’s gains weighed on returns.

Key Factor	Summary	Impact
Communications services	Benefited from overweight exposure to Google’s parent, Alphabet Inc., which posted strong earnings as revenue accelerated across most business segments, while experiencing margin expansion, despite massive, ongoing AI-related investments	Contributed
Johnson Controls International plc	Benefited from better-than-expected revenue and earnings, and guided above expectations as investors remain bullish on the ability of the new CEO to accelerate growth and margin improvement	Contributed
Information technology	Lack of exposure to some key benchmark contributors in the semiconductor and semiconductor equipment industries that rose on optimism regarding AI spending	Detracted
Specialty retail	Overweight sector exposure, particularly overweight exposure to retailers pressured by consumers delaying or downsizing major purchases amid inflationary challenges	Detracted
Semiconductors	Lack of exposure to Micron Technology, Inc. and other key industry names that rallied on strong results amid surging AI-related demand	Detracted
UnitedHealth Group Inc.	Detracted on earnings misses, rising costs and expenses, management turnover, poor execution and a U.S. Department of Justice investigation	Detracted

3.	The Morningstar Large Blend Category Average is representative of funds that represent the overall U.S. stock market in size, growth rates and price. Stocks in the top 70% of the capitalization of the U.S. equity market are defined as large cap. The blend style is assigned to funds where neither growth nor value characteristics predominate. These funds tend to invest across the spectrum of U.S. industries, and owing to their broad exposure, the funds' returns are often similar to those of the S&P 500^® Index. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the FTSE Global Core Infrastructure 50/50 Index (Net) was determined primarily by security selection. Sector allocation also affected relative returns, albeit to a lesser extent.

Key Factor	Summary	Impact
North American utilities	The strongest driver of relative performance, led by exposure to nuclear power owner Constellation Energy Corp.	Contributed
European transportation	Holdings benefited from a mix of European equity market strength, exposure to toll roads and U.S. dollar weakness	Contributed
European utilities	Overweight positioning, with an emphasis on German exposure relative to Spanish utilities	Contributed
Asian infrastructure	Security selection in Japanese rails and Australian toll roads, and underweight exposure to outperforming utilities, particularly in Japan	Detracted
North American midstream	Emphasis on U.S. versus Canada, and holdings in liquified natural gas exporters	Detracted
Global communications	The weakest infrastructure returns, exacerbated by exposure to towers and data centers	Detracted

1.	The Portfolio has selected the MSCI World Index (Net) to represent a broad measure of market performance. The MSCI World Index (Net) is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets.
2.	The FTSE Global Core Infrastructure 50/50 Index (Net), which is generally representative of the market sectors or types of investments in which the Portfolio invests, is a market-capitalization-weighted index of worldwide infrastructure and infrastructure-related securities. Constituent weights are adjusted semi-annually according to three broad industry sectors: 50% utilities, 30% transportation, and a 20% mix of other sectors.
3.	The Morningstar Infrastructure Category Average is representative of funds that invest more than 60% of their assets in stocks of companies engaged in infrastructure activities. Industries considered to be part of the infrastructure sector include: oil & gas midstream; waste management; airports; integrated shipping; railroads; shipping & ports; trucking; engineering & construction; infrastructure operations; and the utilities sector. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Portfolio Performance

The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Portfolio (or for the life of the Portfolio, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period. The Portfolio's subadvisor changed effective January 1, 2018, due to an organizational restructuring whereby all investment personnel of Cornerstone Capital Management Holdings LLC, the former subadvisor, transitioned to MacKay Shields LLC. Effective May 1, 2021, the Portfolio replaced its subadvisor, MacKay Shields LLC, and modified its principal investment strategies. The past performance in the graph and table prior to those dates reflect the Portfolio's subadvisors and principal investment strategies.

1.	The Portfolio has selected the Russell 3000^® Index to represent a broad measure of market performance. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies representing approximately 98% of the investable U.S. equity market.
2.	The Russell 2000^® Index, which is generally representative of the market sectors or types of investments in which the Portfolio invests, measures the performance of the small-cap segment of the U.S. equity universe. It is a subset of the Russell 3000^® Index and includes approximately 2,000 of the smallest securities based on a combination of their market cap and current index membership.
3.	The Morningstar Small Blend Category Average is representative of funds that favor U.S. firms at the smaller end of the market-capitalization range. Some aim to own an array of value and growth stocks while others employ a discipline that leads to holdings with valuations and growth rates close to the small-cap averages. Stocks in the bottom 10% of the capitalization of the U.S. equity market are defined as small cap. The blend style is assigned to funds where neither growth nor value characteristics predominate. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]

What factors influenced Portfolio performance during the reporting period?

During the 12-month reporting period ended December 31, 2025, the Portfolio’s performance relative to the S&P Balanced Equity and Bond - Conservative Index was led by equity exposures, with particularly strong contributions from international and emerging-markets equities, as improving global growth expectations, easing financial conditions and select regional policy support drove risk asset appreciation. Fixed income strategies also contributed meaningfully, supported by attractive carry and spread compression in floating-rate credit, convertibles and shorter duration exposures amid a gradual normalization of inflation and interest rates. These gains were partially offset by currency positioning, where U.S. dollar weakness and volatility across major developed currencies detracted from returns, while alternative and commodity strategies provided modest diversification benefits.

Key Factor	Summary	Impact
International core equity	Bolstered by improving global growth expectations, easing financial conditions, local currency strengthening and supportive policy developments across developed international markets	Contributed
Convertible securities	Benefited from robust equity markets that enhanced conversion value, alongside spread compression and stable credit fundamentals that supported the bond component of returns	Contributed
Emerging-markets broad equity	Positive sentiment fueled by a weaker U.S. dollar for much of the period, improving growth prospects and selective policy support	Contributed
International Treasury	Short allocation as global sovereign yields declined amid slowing inflation and expectations for monetary easing, driving bond price appreciation	Detracted
Euro currency	Short euro position as the currency strengthened on narrowing rate differentials and improved regional growth sentiment	Detracted
U.S. health care	Short allocation amid a strong second-half rebound prompted by softening regulatory uncertainty, increased defensive demand, stable earnings and renewed investor interest in health care	Detracted

Effective November 30, 2018, the Portfolio entered into a reorganization with MainStay VP Absolute Return Multi-Strategy Portfolio (the "Reorganization"). As part of the Reorganization, the Portfolio assumed the performance history of MainStay VP Absolute Return Multi-Strategy Portfolio. Therefore, performance information for periods prior to November 30, 2018, reflects the performance of MainStay VP Absolute Return Multi-Strategy Portfolio.

Stocks in the top 70% of the capitalization of the U.S. equity market are defined as large cap. The blend style is assigned to funds where neither growth nor value characteristics predominate. These funds tend to invest across the spectrum of U.S. industries, and owing to their broad exposure, the funds' returns are often similar to those of the S&P 500^® Index. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.
