Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, asset class positioning, which is primarily driven by volatility management, contributed to the fund's performance versus the Composite index for the year, whereas security selection detracted.
The portfolio's core equity allocation strategy aided the portfolio's relative outcome. Specifically, a roughly equal weight allocation to international developed- and emerging markets stocks added considerable value this period, as returns in these asset classes substantially outperformed U.S. equities in 2025. Reflecting this performance disparity, an approximately equal weight position in U.S. stocks modestly detracted, slightly diminishing the positive impact of our equity allocation approach. 
The fund's fixed-income positioning moderately hurt. While adjustments made to the fund's cash position during the year helped, a slight underweight in investment-grade bonds pressured performance.
From a security selection standpoint, picks among both developed- and emerging-markets equities weighed on relative performance due to disappointing results from Fidelity® Overseas Fund and, to a lesser extent, Fidelity® Emerging Markets Fund.
Stock selection in the U.S. boosted the fund's relative result, led by Fidelity® VIP Stock Selector Portfolio, the largest holding this period. Here, investment choices in the communication services and financials sectors helped most. A stake in Fidelity® Stock Selector Small Cap Fund was another plus. Conversely, exposure to Fidelity® Enhanced Large Cap Core ETF modestly detracted. 
Turning to fixed-income, an investment in Fidelity® Total Bond Fund stood out to the upside in terms of security selection. 
As of December 31, the fund maintained a slight overweight in U.S. stocks, along with roughly equal-weight allocations in international developed- and emerging-markets equities. We decreased the portfolio's U.S. and international equity allocations this period and increased exposure to investment-grade bond holdings. As of year-end, our investment-grade bond positioning was close to the fund's target weight, while cash was slightly below.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world largely achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, compared with the Fidelity Strategic Income Composite IndexSM, security selection in the fund's high-yield bond subportfolio meaningfully contributed to the fund's result, especially its out-of-benchmark equity holdings. Picks in the telecommunications and technology & electronics groups contributed the most.
In addition, the fund's out-of-benchmark allocation to U.S. Treasury futures, a position we established to help offset the portfolio's overall lower duration, outperformed in a generally falling interest-rate environment. 
Investment choices in emerging-markets debt also added value relative to the Composite index, with bond picks in Venezuela being notable standouts. 
Changes to the portfolio this period included adding to high-yield bonds and floating-rate loans, while reducing the fund's allocation to U.S. Treasurys.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world largely achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, compared with the Fidelity Strategic Income Composite IndexSM, security selection in the fund's high-yield bond subportfolio meaningfully contributed to the fund's result, especially its out-of-benchmark equity holdings. Picks in the telecommunications and technology & electronics groups contributed the most.
In addition, the fund's out-of-benchmark allocation to U.S. Treasury futures, a position we established to help offset the portfolio's overall lower duration, outperformed in a generally falling interest-rate environment. 
Investment choices in emerging-markets debt also added value relative to the Composite index, with bond picks in Venezuela being notable standouts. 
Changes to the portfolio this period included adding to high-yield bonds and floating-rate loans, while reducing the fund's allocation to U.S. Treasurys.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index the past year, especially in non-U.S. developed-market equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.32%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.39%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.81% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an overweight in long-term U.S. Treasury bonds detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index the past year, especially in non-U.S. developed-market equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.32%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.39%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.81% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an overweight in long-term U.S. Treasury bonds detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index the past year, especially in non-U.S. developed-market equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.32%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.39%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.81% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index the past year, especially in non-U.S. developed-market equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.32%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.39%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.81% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an overweight in long-term U.S. Treasury bonds detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index the past year, especially in non-U.S. developed-market equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.32%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.39%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.81% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an overweight in long-term U.S. Treasury bonds detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. taxable investment-grade bonds advanced in 2025, navigating uncertainty related to U.S. trade policy but buoyed by elevated starting yields, tighter credit spreads and three policy interest-rate cuts by the U.S. Federal Reserve since September 17. 
Against that backdrop, the fund's modestly longer duration (i.e., slightly more interest-rate sensitivity) contributed to performance versus the Bloomberg U.S. Aggregate Index for the year.  
Security selection also added value. Specifically, fund holdings in the corporate segment made a modest contribution to relative performance, led by picks among financials, particularly banks and REITs.
In the government-related sector, non-index exposure to bonds issued by Mexico's state-owned oil and gas company Pemex (Petroleos Mexicanos) buoyed relative performance as well. 
Overweight holdings and investment choices among asset-backed securities, particularly collateralized loan obligations, and commercial mortgage-backed securities, helped. 
In contrast, the fund's underweight in mortgage-backed securities detracted versus the benchmark.
An underweight in the bonds of industrial firms within the corporate sector also hurt. 
Notable changes over the past 12 months included management's decision to gradually lower the fund's overall risk profile by reducing exposure to investment-grade corporate bonds and increasing the allocation to U.S. Treasurys.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. taxable investment-grade bonds advanced in 2025, navigating uncertainty related to U.S. trade policy but buoyed by elevated starting yields, tighter credit spreads and three policy interest-rate cuts by the U.S. Federal Reserve since September 17. 
Against that backdrop, the fund's modestly longer duration (i.e., slightly more interest-rate sensitivity) contributed to performance versus the Bloomberg U.S. Aggregate Index for the year.  
Security selection also added value. Specifically, fund holdings in the corporate segment made a modest contribution to relative performance, led by picks among financials, particularly banks and REITs.
In the government-related sector, non-index exposure to bonds issued by Mexico's state-owned oil and gas company Pemex (Petroleos Mexicanos) buoyed relative performance as well. 
Overweight holdings and investment choices among asset-backed securities, particularly collateralized loan obligations, and commercial mortgage-backed securities, helped. 
In contrast, the fund's underweight in mortgage-backed securities detracted versus the benchmark.
An underweight in the bonds of industrial firms within the corporate sector also hurt. 
Notable changes over the past 12 months included management's decision to gradually lower the fund's overall risk profile by reducing exposure to investment-grade corporate bonds and increasing the allocation to U.S. Treasurys.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, asset class positioning contributed to the Portfolios' performance versus the Composite indexes for the year, whereas security selection detracted.
The Portfolios' core equity allocation strategy contributed to relative performance, led by outsized exposure to both international developed- and emerging-markets stocks. Conversely, an overweight among U.S. equities detracted from the Portfolios' relative outcomes in 2025. 
The Portfolios' fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025, led by solid performance from Fidelity® VIP Stock Selector Portfolio, the largest equity holding this period. Here, investment choices in the communication services and financials sectors contributed the most.
Stock selection among international developed-market stocks, on the other hand, significantly pressured the Portfolios' relative returns, hampered mostly by disappointing results from Fidelity® Overseas Fund. Specifically, picks in Germany and several other continental European equity markets, as well as the U.K. and Canada, were the biggest negatives. Non-Composite allocations to the U.S. market also hurt. 
Investment choices in emerging-markets equities proved to be a challenge as well the past year, as out-of-index positioning in the Europe ex-U.K. region weighed on the performance of Fidelity® Emerging Markets Fund. 
Turning to fixed income, security selection among investment-grade bonds added value, driven by the efforts of our active bond fund managers. 
As of December 31, the Portfolios were overweight equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

The Portfolios' core equity allocation strategy contributed to relative performance, led by outsized exposure to both international developed- and emerging-markets stocks. Conversely, an overweight among U.S. equities detracted from the Portfolios' relative outcomes in 2025. 
The Portfolios' fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025, led by solid performance from Fidelity® VIP Stock Selector Portfolio, the largest equity holding this period. Here, investment choices in the communication services and financials sectors contributed the most.
Stock selection among international developed-market stocks, on the other hand, significantly pressured the Portfolios' relative returns, hampered mostly by disappointing results from Fidelity® Overseas Fund. Specifically, picks in Germany and several other continental European equity markets, as well as the U.K. and Canada, were the biggest negatives. Non-Composite allocations to the U.S. market also hurt. 
Investment choices in emerging-markets equities proved to be a challenge as well the past year, as out-of-index positioning in the Europe ex-U.K. region weighed on the performance of Fidelity® Emerging Markets Fund. 
Turning to fixed income, security selection among investment-grade bonds added value, driven by the efforts of our active bond fund managers. 
As of December 31, the Portfolios were overweight equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, asset class positioning contributed to the Portfolios' performance versus the Composite indexes for the year, whereas security selection detracted.
The Portfolios' core equity allocation strategy contributed to relative performance, led by outsized exposure to both international developed- and emerging-markets stocks. Conversely, an overweight among U.S. equities detracted from the Portfolios' relative outcomes in 2025. 
The Portfolios' fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025, led by solid performance from Fidelity® VIP Stock Selector Portfolio, the largest equity holding this period. Here, investment choices in the communication services and financials sectors contributed the most.
Stock selection among international developed-market stocks, on the other hand, significantly pressured the Portfolios' relative returns, hampered mostly by disappointing results from Fidelity® Overseas Fund. Specifically, picks in Germany and several other continental European equity markets, as well as the U.K. and Canada, were the biggest negatives. Non-Composite allocations to the U.S. market also hurt. 
Investment choices in emerging-markets equities proved to be a challenge as well the past year, as out-of-index positioning in the Europe ex-U.K. region weighed on the performance of Fidelity® Emerging Markets Fund. 
Turning to fixed income, security selection among investment-grade bonds added value, driven by the efforts of our active bond fund managers. 
As of December 31, the Portfolios were overweight equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, asset class positioning contributed to the Portfolios' performance versus the Composite indexes for the year, whereas security selection detracted.
The Portfolios' core equity allocation strategy contributed to relative performance, led by outsized exposure to both international developed- and emerging-markets stocks. Conversely, an overweight among U.S. equities detracted from the Portfolios' relative outcomes in 2025. 
The Portfolios' fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025, led by solid performance from Fidelity® VIP Stock Selector Portfolio, the largest equity holding this period. Here, investment choices in the communication services and financials sectors contributed the most.
Stock selection among international developed-market stocks, on the other hand, significantly pressured the Portfolios' relative returns, hampered mostly by disappointing results from Fidelity® Overseas Fund. Specifically, picks in Germany and several other continental European equity markets, as well as the U.K. and Canada, were the biggest negatives. Non-Composite allocations to the U.S. market also hurt. 
Investment choices in emerging-markets equities proved to be a challenge as well the past year, as out-of-index positioning in the Europe ex-U.K. region weighed on the performance of Fidelity® Emerging Markets Fund. 
Turning to fixed income, security selection among investment-grade bonds added value, driven by the efforts of our active bond fund managers. 
As of December 31, the Portfolios were overweight equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Against this backdrop, asset class positioning contributed to the Portfolios' performance versus the Composite indexes for the year, whereas security selection detracted.
The Portfolios' core equity allocation strategy contributed to relative performance, led by outsized exposure to both international developed- and emerging-markets stocks. Conversely, an overweight among U.S. equities detracted from the Portfolios' relative outcomes in 2025. 
The Portfolios' fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025, led by solid performance from Fidelity® VIP Stock Selector Portfolio, the largest equity holding this period. Here, investment choices in the communication services and financials sectors contributed the most.
Stock selection among international developed-market stocks, on the other hand, significantly pressured the Portfolios' relative returns, hampered mostly by disappointing results from Fidelity® Overseas Fund. Specifically, picks in Germany and several other continental European equity markets, as well as the U.K. and Canada, were the biggest negatives. Non-Composite allocations to the U.S. market also hurt. 
Investment choices in emerging-markets equities proved to be a challenge as well the past year, as out-of-index positioning in the Europe ex-U.K. region weighed on the performance of Fidelity® Emerging Markets Fund. 
Turning to fixed income, security selection among investment-grade bonds added value, driven by the efforts of our active bond fund managers. 
As of December 31, the Portfolios were overweight equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, asset class positioning contributed to the Portfolios' performance versus the Composite indexes for the year, whereas security selection detracted.
The Portfolios' core equity allocation strategy contributed to relative performance, led by outsized exposure to both international developed- and emerging-markets stocks. Conversely, an overweight among U.S. equities detracted from the Portfolios' relative outcomes in 2025. 
The Portfolios' fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025, led by solid performance from Fidelity® VIP Stock Selector Portfolio, the largest equity holding this period. Here, investment choices in the communication services and financials sectors contributed the most.
Stock selection among international developed-market stocks, on the other hand, significantly pressured the Portfolios' relative returns, hampered mostly by disappointing results from Fidelity® Overseas Fund. Specifically, picks in Germany and several other continental European equity markets, as well as the U.K. and Canada, were the biggest negatives. Non-Composite allocations to the U.S. market also hurt. 
Investment choices in emerging-markets equities proved to be a challenge as well the past year, as out-of-index positioning in the Europe ex-U.K. region weighed on the performance of Fidelity® Emerging Markets Fund. 
Turning to fixed income, security selection among investment-grade bonds added value, driven by the efforts of our active bond fund managers. 
As of December 31, the Portfolios were overweight equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index the past year, especially in non-U.S. developed-market equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.32%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.39%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.81% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. taxable investment-grade bonds advanced in 2025, navigating uncertainty related to U.S. trade policy but buoyed by elevated starting yields, tighter credit spreads and three policy interest-rate cuts by the U.S. Federal Reserve since September 17. 
Against that backdrop, we constructed the portfolio using optimization. This approach minimizes the differences between risk exposures of the fund relative to the index. 
Exposures include duration, key rate durations, credit quality, sector and issuer allocation, and other factors. 
The fund lagged the index primarily due to pricing basis, meaning differences between when the fund and the index are priced on the last day of the year.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. taxable investment-grade bonds advanced in 2025, navigating uncertainty related to U.S. trade policy but buoyed by elevated starting yields, tighter credit spreads and three policy interest-rate cuts by the U.S. Federal Reserve since September 17. 
Against that backdrop, we constructed the portfolio using optimization. This approach minimizes the differences between risk exposures of the fund relative to the index. 
Exposures include duration, key rate durations, credit quality, sector and issuer allocation, and other factors. 
The fund lagged the index primarily due to pricing basis, meaning differences between when the fund and the index are priced on the last day of the year.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, both asset class positioning and security selection contributed to the fund's performance versus the Composite index for the year.
The portfolio's core equity allocation strategy aided relative performance, led by overweight positioning among in both international developed- and emerging-markets stocks. Conversely, an overweight stake in U.S. equities detracted, modestly diminishing the positive impact of our equity allocation approach. Small, non-index allocations to real estate investment trusts and commodity-related securities marginally dampened the fund's relative result the past year.
The portfolio's fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025. Investment choices in the communication services and financials sectors helped most. 
Stock selection among international developed-market stocks, on the other hand, significantly pressured the fund's relative return. Here, picks in the U.K., along with adverse positioning in Canada and several continental European equity markets, were the biggest negatives. Out-of-benchmark positioning in the U.S. market also hurt. On the plus side, underweighting the lagging Australian market was beneficial. 
Emerging-markets stock picks provided a further boost. Here, positioning in India, along with investment choices in Taiwan and South Korea, added value. 
Security selection among investment-grade bonds also slightly contributed. Non-government-agency mortgage-backed securities and U.S. Treasurys led the way, followed by asset-backed securities.
As of December 31, the fund was overweight in equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, both asset class positioning and security selection contributed to the fund's performance versus the Composite index for the year.
The portfolio's core equity allocation strategy aided relative performance, led by overweight positioning among in both international developed- and emerging-markets stocks. Conversely, an overweight stake in U.S. equities detracted, modestly diminishing the positive impact of our equity allocation approach. Small, non-index allocations to real estate investment trusts and commodity-related securities marginally dampened the fund's relative result the past year.
The portfolio's fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025. Investment choices in the communication services and financials sectors helped most. 
Stock selection among international developed-market stocks, on the other hand, significantly pressured the fund's relative return. Here, picks in the U.K., along with adverse positioning in Canada and several continental European equity markets, were the biggest negatives. Out-of-benchmark positioning in the U.S. market also hurt. On the plus side, underweighting the lagging Australian market was beneficial. 
Emerging-markets stock picks provided a further boost. Here, positioning in India, along with investment choices in Taiwan and South Korea, added value. 
Security selection among investment-grade bonds also slightly contributed. Non-government-agency mortgage-backed securities and U.S. Treasurys led the way, followed by asset-backed securities.
As of December 31, the fund was overweight in equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, both asset class positioning and security selection contributed to the fund's performance versus the Composite index for the year.
The portfolio's core equity allocation strategy aided relative performance, led by overweight positioning among in both international developed- and emerging-markets stocks. Conversely, an overweight stake in U.S. equities detracted, modestly diminishing the positive impact of our equity allocation approach. 
The portfolio's fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025. Investment choices in the communication services and financials sectors helped most. 
Stock selection among international developed-market stocks, on the other hand, significantly pressured the fund's relative return. Here, picks in the U.K., along with adverse positioning in Canada and several continental European equity markets, were the biggest negatives. Out-of-benchmark positioning in the U.S. market also hurt. On the plus side, underweighting the lagging Australian market was beneficial. 
Emerging-markets stock picks provided a further boost. Here, positioning in India, along with investment choices in Taiwan and South Korea, added value. 
Security selection among investment-grade bonds also slightly contributed. Non-government-agency mortgage-backed securities and U.S. Treasurys led the way, followed by asset-backed securities.
As of December 31, the fund was overweight in equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Risk assets throughout the world achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some key central banks.
Against this backdrop, both asset class positioning and security selection contributed to the fund's performance versus the Composite index for the year.
The portfolio's core equity allocation strategy aided relative performance, led by overweight positioning among in both international developed- and emerging-markets stocks. Conversely, an overweight stake in U.S. equities detracted, modestly diminishing the positive impact of our equity allocation approach. 
The portfolio's fixed-income positioning was beneficial from a relative performance standpoint. Specifically, an underweight in investment-grade bond holdings and cash, in favor of higher-risk segments of the fixed-income market was advantageous. That said, small allocations to long-term U.S. Treasurys and leveraged loans hurt modestly. 
In terms of security selection, picks among U.S. equities notably aided relative performance in 2025. Investment choices in the communication services and financials sectors helped most. 
Stock selection among international developed-market stocks, on the other hand, significantly pressured the fund's relative return. Here, picks in the U.K., along with adverse positioning in Canada and several continental European equity markets, were the biggest negatives. Out-of-benchmark positioning in the U.S. market also hurt. On the plus side, underweighting the lagging Australian market was beneficial. 
Emerging-markets stock picks provided a further boost. Here, positioning in India, along with investment choices in Taiwan and South Korea, added value. 
Security selection among investment-grade bonds also slightly contributed. Non-government-agency mortgage-backed securities and U.S. Treasurys led the way, followed by asset-backed securities.
As of December 31, the fund was overweight in equities across the board - U.S. as well as international developed and emerging markets - though we remained underweight investment-grade bonds and cash.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. taxable investment-grade bonds advanced in 2025, navigating uncertainty related to U.S. trade policy but buoyed by elevated starting yields, tighter credit spreads and three policy interest-rate cuts by the U.S. Federal Reserve since September 17. 
Against that backdrop, the fund's modestly longer duration (i.e., slightly more interest-rate sensitivity) contributed to performance versus the Bloomberg U.S. Aggregate Index for the year.  
Security selection also added value. Specifically, fund holdings in the corporate segment made a modest contribution to relative performance, led by picks among financials, particularly banks and REITs.
In the government-related sector, non-index exposure to bonds issued by Mexico's state-owned oil and gas company Pemex (Petroleos Mexicanos) buoyed relative performance as well. 
Overweight holdings and investment choices among asset-backed securities, particularly collateralized loan obligations, and commercial mortgage-backed securities, helped.  
In contrast, the fund's underweight in mortgage-backed securities detracted versus the benchmark.
An underweight in the bonds of industrial firms within the corporate sector also hurt. 
Notable changes over the past 12 months included management's decision to gradually lower the fund's overall risk profile by reducing exposure to investment-grade corporate bonds and increasing the allocation to U.S. Treasurys.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. taxable investment-grade bonds advanced in 2025, navigating uncertainty related to U.S. trade policy but buoyed by elevated starting yields, tighter credit spreads and three policy interest-rate cuts by the U.S. Federal Reserve since September 17. 
Against that backdrop, the fund's modestly longer duration (i.e., slightly more interest-rate sensitivity) contributed to performance versus the Bloomberg U.S. Aggregate Index for the year.  
Security selection also added value. Specifically, fund holdings in the corporate segment made a modest contribution to relative performance, led by picks among financials, particularly banks and REITs.
In the government-related sector, non-index exposure to bonds issued by Mexico's state-owned oil and gas company Pemex (Petroleos Mexicanos) buoyed relative performance as well. 
Overweight holdings and investment choices among asset-backed securities, particularly collateralized loan obligations, and commercial mortgage-backed securities, helped.  
In contrast, the fund's underweight in mortgage-backed securities detracted versus the benchmark.
An underweight in the bonds of industrial firms within the corporate sector also hurt. 
Notable changes over the past 12 months included management's decision to gradually lower the fund's overall risk profile by reducing exposure to investment-grade corporate bonds and increasing the allocation to U.S. Treasurys.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
Global risk assets achieved strong gains in 2025, boosted by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some global central banks.
Against this backdrop, the performance of the underlying investment portfolios detracted from the Fund's performance versus the Composite index for the year, especially in non-U.S. equities.
Within non-U.S. equities, an investment in VIP Overseas Portfolio hurt most, as the fund gained 20.39%, trailing the 32.22% advance of the MSCI ACWI (All Country World Index) ex US Index.
Performance among U.S. equities contributed to the Fund's relative performance, especially an investment in VIP Growth & Income Portfolio (+21.50%), which topped its benchmark, the S&P 500 index (+17.88%).
Conversely, an investment in VIP Growth Portfolio detracted from the Fund's relative result, given the portfolio's 14.90% gain lagged that of its benchmark, the Russell 3000® Growth Index (+18.15%).
Active asset allocation positioning contributed to the Fund's performance versus its Composite index. Specifically, it helped to overweight non-U.S. equities, the top-performing category in 2025. Underweighting U.S. investment-grade bonds also contributed, whereas an underweight in U.S. equities detracted.
