The Lifestyle Growth PS Series, Lifestyle Moderate PS Series, Lifestyle Balanced PS Series and Lifestyle Conservative PS Series (collectively, the “JHVIT Lifestyle PS Series”) and the Bond PS Series are offered only in connection with specific guaranteed benefits under variable annuity contracts issued by John Hancock Life Insurance Company (U.S.A.) and John Hancock Life Insurance Company of New York (collectively, “John Hancock Issuers”). The Contracts provide that the John Hancock Issuers can automatically transfer contract value between the Lifestyles PS Series and the Bond PS Series through a non-discretionary, systematic mathematical process. The purpose of these transfers is to attempt to protect contract value from declines due to market volatility, and thereby limit the John Hancock Issuers’ exposure to risk on certain guaranteed benefits under the Contracts. The timing and amount of any transfer of contract value under the John Hancock Issuers’ process will depend on several factors including market movements. In general, the higher the equity component of a JHVIT Lifestyle PS Series, the more likely that contract value will be reallocated from a JHVIT Lifestyle PS Series fund to the Bond PS Series when equity markets fall. These asset reallocations may result in large-scale asset flows into and out of the Bond PS Series, which may negatively affect the fund’s performance by increasing the fund’s transaction costs and causing it to purchase or sell securities when it would not normally do so. It could be particularly disadvantageous for the Bond PS Series if it experiences outflows and needs to sell securities at a time when interest rates are rising and the prices of fixed-income securities are declining. Outflows may also increase the fund’s expense ratio. Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract spot transaction, currency forwards, currency options or other over-the-counter derivatives contracts or a borrower of a fund’s securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund’s share price and income level. Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments. Investments in emerging-market countries are subject to greater levels of foreign investment risk. Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price. Swaps Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, risk of default of the underlying reference obligation and risk of disproportionate loss are the principal risks of engaging in transactions involving swaps, including credit default swaps and total return swaps.Foreign currency forward contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions(, foreign currency risk and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency forward contracts.Futures contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving futures contracts.Options Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving over-the-counter options. Counterparty risk does not apply to exchange-traded options.High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance). Issuer risk An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by the fund could default or have its credit rating downgraded. Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price. Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

PS Series Asset Transfer Risk. The fund is an underlying fund of the Lifestyle Growth PS Series, Lifestyle Moderate PS Series, Lifestyle Balanced PS Series and Lifestyle Conservative PS Series (collectively, the “JHVIT Lifestyle PS Series”) which are offered only in connection with specific guaranteed benefits under variable annuity contracts issued by John Hancock Life Insurance Company (U.S.A.) and John Hancock Life Insurance Company of New York (collectively, “John Hancock Issuers”). The Contracts provide that the John Hancock Issuers can automatically transfer contract value between the Lifestyles PS Series and the Bond PS Series through a non-discretionary, systematic mathematical process. The purpose of these transfers is to attempt to protect contract value from declines due to market volatility, and thereby limit the John Hancock Issuers’ exposure to risk on certain guaranteed benefits under the Contracts. The timing and amount of any transfer of contract value under the John Hancock Issuers’ process will depend on several factors including market movements. In general, the higher the equity component of a JHVIT Lifestyle PS Series, the more likely that contract value will be reallocated from the JHVIT Lifestyle PS Series fund to the Bond PS Series when equity markets fall. These asset reallocations may, therefore, result in large-scale asset flows into and out of the JHVIT Lifestyle PS Series and, consequently, into and out of underlying funds in which the JHVIT Lifestyle PS Series invest. These asset flows may negatively affect an underlying fund’s performance by increasing the fund’s transaction costs and causing it to purchase, or sell securities when it would not normally do so. It could be particularly disadvantageous for an underlying fund if it experiences outflows and needs to sell securities at a time of volatility in the markets, when values could be falling. Outflows may also increase the fund’s expense ratio. Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract spot transaction, currency forwards, currency options or other over-the-counter derivatives contracts or a borrower of a fund’s securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund’s share price and income level. Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track. Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests. Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments. Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price. Swaps Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, risk of default of the underlying reference obligation and risk of disproportionate loss are the principal risks of engaging in transactions involving swaps including credit default swaps and total return swaps. Foreign currency forward contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions(, foreign currency risk and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency forward contracts. Futures contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving futures contracts. Options Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving over-the-counter options. Counterparty risk does not apply to exchange-traded options. Issuer risk An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by the fund could default or have its credit rating downgraded. Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price. Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

At the discretion of the subadviser, the Equity Allocation may also include direct investments in equity securities and the Fixed Income Allocation may also include direct investments in fixed-income securities. The subadviser may also determine in light of market or economic conditions that the normal percentage limitations should be exceeded to protect the fund or achieve its objective.Within the prescribed percentage allocation, the subadviser selects the percentage level to be maintained in specific underlying funds. These allocations may be changed at any time by the subadviser.The fund may invest in various underlying funds that as a group hold a wide range of equity type securities in their funds. These include small-, mid- and large-capitalization stocks, domestic and foreign securities (including emerging market securities) and sector holdings such as utilities and science and technology stocks. Each of these underlying funds has its own investment strategy which, for example, may focus on growth stocks or value stocks or may employ a strategy combining growth and income stocks and/or may invest in derivatives such as options on securities and futures contracts. The fund may also invest in underlying funds that purchase futures contracts on equity markets.Certain of these underlying funds focus their investment strategy on fixed-income securities, which may include investment grade and below investment grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage backed, government issued, domestic and international securities.The fund may also invest in the securities of other investment companies including exchange-traded funds (ETFs) and may make direct investments in other types of investments. See “Other Permitted Investments of the Fund of Funds.”The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests.Use of Hedging and Other Strategic Transactions.

The principal risks of investing in the fund include:Active management risk The subadviser’s investment strategy may fail to produce the intended result.PS Series Asset Transfer Risk.The Lifestyle Growth PS Series, Lifestyle Moderate PS Series, Lifestyle Balanced PS Series and Lifestyle Conservative PS Series (collectively, the “JHVIT Lifestyle PS Series”) and the Bond PS Series are offered only in connection with specific guaranteed benefits under variable annuity contracts (the “Contracts”) issued by John Hancock Life Insurance Company (U.S.A.) and John Hancock Life Insurance Company of New York (collectively, the “John Hancock Issuers”). The Contracts provide that the John Hancock Issuers can automatically transfer contract value between the Lifestyles PS Series and the Bond PS Series through a non-discretionary, systematic mathematical process. The purpose of these transfers is to attempt to protect contract value from declines due to market volatility, and thereby limit the John Hancock Issuers’ exposure to risk on certain guaranteed benefits under the Contracts. The timing and amount of any transfer of contract value under the John Hancock Issuers’ process will depend on several factors including market movements. In general, the higher the equity component of a JHVIT Lifestyle PS Series, the more likely that contract value will be reallocated from the JHVIT Lifestyle PS Series to the Bond PS Series when equity markets fall. These asset flows may negatively affect the performance of an underlying fund in which the JHVIT Lifestyle PS Series invests by increasing the underlying fund’s transaction costs and causing it to purchase or sell securities when it would not normally do so. It could be particularly disadvantageous for the underlying fund if it experiences outflows and needs to sell securities at a time of volatility in the markets, when values could be falling. Because the JHVIT Lifestyle PS Series bear their proportionate share of the transaction costs of the underlying funds, increased underlying fund expenses may indirectly negatively affect the performance of the JHVIT Lifestyle PS Series.Commodity risk Commodity investments involve the risk of volatile market price fluctuations of commodities resulting from fluctuating demand, supply disruption, speculation and other factors.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Investment company securities risk The fund bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.Principal Risks of Investing in the Underlying FundsActive management risk The subadviser’s investment strategy may fail to produce the intended result.Convertible securities risk The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In addition, as the market price of the underlying common stock declines below the conversion price, the price of the convertible security tends to be increasingly influenced more by the yield of the convertible security.Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract spot transaction, currency forwards, currency options or other over-the-counter derivatives contracts, or a borrower of a fund’s securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund’s share price and income level.Equity securities risk The value of a company’s equity securities is subject to changes in the company’s financial condition, and overall market and economic conditions. The securities of growth companies are subject to greater price fluctuations than other types of stocks because their market prices tend to place greater emphasis on future earnings expectations. The securities of value companies are subject to the risk that the companies may not overcome the adverse business developments or other factors causing their securities to be underpriced or that the market may never come to recognize their fundamental value.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments.Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments. Investments in emerging-market countries are subject to greater levels of foreign investment risk.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Industry or sector risk Because the fund may focus on one or more industry or sector of the economy, its performance depends in large part on the performance of those sectors or industries. As a result, the value of your investment may fluctuate more widely than it would in a fund that is diversified across industries and sectors.Initial public offerings risk IPO shares may have a magnified impact on fund performance and are frequently volatile in price. They can be held for a short period of time causing an increase in portfolio turnover.Issuer risk An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by the fund could default or have its credit rating downgraded.Large company risk Large-capitalization stocks as a group could fall out of favor with the market, causing the fund to underperform investments that focus on small- or medium- capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price.Lower-rated fixed-income securities risk and high-yield securities risk Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as junk bonds) are subject to greater credit-quality risk and risk of default than higher-rated fixed-income securities. These securities may be considered speculative and the value of these securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market or economic developments and can be difficult to resell.Medium and smaller company risk The prices of medium and smaller company stocks can change more frequently and dramatically than those of large company stocks. For purposes of the fund’s investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company’s securities. Market capitalizations of companies change over time.Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.Non-diversified risk Overall risk can be reduced by investing in securities from a diversified pool of issuers, while overall risk is increased by investing in securities of a small number of issuers.Short sales risk Short sales involve costs and risk. The fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

These allocations may be changed at any time by the subadviser.The fund may invest in various underlying funds that as a group hold a wide range of equity type securities in their funds. These include small-, mid- and large-capitalization stocks, domestic and foreign securities (including emerging market securities) and sector holdings such as utilities and science and technology stocks.

The fund may also invest in underlying funds that purchase futures contracts on equity markets.Certain of these underlying funds focus their investment strategy on fixed-income securities, which may include investment grade and below investment grade debt securities with maturities that range from short to longer term.

The Lifestyle Growth PS Series, Lifestyle Moderate PS Series, Lifestyle Balanced PS Series and Lifestyle Conservative PS Series (collectively, the “JHVIT Lifestyle PS Series”) and the Bond PS Series are offered only in connection with specific guaranteed benefits under variable annuity contracts (the “Contracts”) issued by John Hancock Life Insurance Company (U.S.A.) and John Hancock Life Insurance Company of New York (collectively, the “John Hancock Issuers”). The Contracts provide that the John Hancock Issuers can automatically transfer contract value between the Lifestyles PS Series and the Bond PS Series through a non-discretionary, systematic mathematical process. The purpose of these transfers is to attempt to protect contract value from declines due to market volatility, and thereby limit the John Hancock Issuers’ exposure to risk on certain guaranteed benefits under the Contracts. The timing and amount of any transfer of contract value under the John Hancock Issuers’ process will depend on several factors including market movements. In general, the higher the equity component of a JHVIT Lifestyle PS Series, the more likely that contract value will be reallocated from the JHVIT Lifestyle PS Series to the Bond PS Series when equity markets fall. These asset flows may negatively affect the performance of an underlying fund in which the JHVIT Lifestyle PS Series invests by increasing the underlying fund’s transaction costs and causing it to purchase or sell securities when it would not normally do so. It could be particularly disadvantageous for the underlying fund if it experiences outflows and needs to sell securities at a time of volatility in the markets, when values could be falling. Because the JHVIT Lifestyle PS Series bear their proportionate share of the transaction costs of the underlying funds, increased underlying fund expenses may indirectly negatively affect the performance of the JHVIT Lifestyle PS Series.Commodity risk Commodity investments involve the risk of volatile market price fluctuations of commodities resulting from fluctuating demand, supply disruption, speculation and other factors.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Investment company securities risk The fund bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.Principal Risks of Investing in the Underlying FundsActive management risk The subadviser’s investment strategy may fail to produce the intended result.Convertible securities risk The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In addition, as the market price of the underlying common stock declines below the conversion price, the price of the convertible security tends to be increasingly influenced more by the yield of the convertible security.Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract spot transaction, currency forwards, currency options or other over-the-counter derivatives contracts, or a borrower of a fund’s securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund’s share price and income level.Equity securities risk The value of a company’s equity securities is subject to changes in the company’s financial condition, and overall market and economic conditions. The securities of growth companies are subject to greater price fluctuations than other types of stocks because their market prices tend to place greater emphasis on future earnings expectations. The securities of value companies are subject to the risk that the companies may not overcome the adverse business developments or other factors causing their securities to be underpriced or that the market may never come to recognize their fundamental value.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments.Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments. Investments in emerging-market countries are subject to greater levels of foreign investment risk.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Industry or sector risk Because the fund may focus on one or more industry or sector of the economy, its performance depends in large part on the performance of those sectors or industries. As a result, the value of your investment may fluctuate more widely than it would in a fund that is diversified across industries and sectors.Initial public offerings risk IPO shares may have a magnified impact on fund performance and are frequently volatile in price. They can be held for a short period of time causing an increase in portfolio turnover.Issuer risk An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by the fund could default or have its credit rating downgraded.Large company risk Large-capitalization stocks as a group could fall out of favor with the market, causing the fund to underperform investments that focus on small- or medium- capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price.Lower-rated fixed-income securities risk and high-yield securities risk Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as “junk bonds”) are subject to greater credit-quality risk and risk of default than higher-rated fixed-income securities. These securities may be considered speculative and the value of these securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market or economic developments and can be difficult to resell.Medium and smaller company risk The prices of medium and smaller company stocks can change more frequently and dramatically than those of large company stocks. For purposes of the fund’s investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company’s securities. Market capitalizations of companies change over time.Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.Non-diversified risk Overall risk can be reduced by investing in securities from a diversified pool of issuers, while overall risk is increased by investing in securities of a small number of issuers.Short sales risk Short sales involve costs and risk. The fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

At the discretion of the subadviser, the Equity Allocation may also include direct investments in equity securities and the Fixed Income Allocation may also include direct investments in fixed-income securities. The subadviser may also determine in light of market or economic conditions that the normal percentage limitations should be exceeded to protect the fund or achieve its objective.Within the prescribed percentage allocation, the subadviser selects the percentage level to be maintained in specific underlying funds. These allocations may be changed at any time by the subadviser.The fund may invest in various underlying funds that as a group hold a wide range of equity type securities in their funds. These include small-, mid- and large-capitalization stocks, domestic and foreign securities (including emerging market securities) and sector holdings such as utilities and science and technology stocks. Each of these underlying funds has its own investment strategy which, for example, may focus on growth stocks or value stocks or may employ a strategy combining growth and income stocks and/or may invest in derivatives such as options on securities and futures contracts. The fund may also invest in underlying funds that purchase futures contracts on equity markets.Certain of these underlying funds focus their investment strategy on fixed-income securities, which may include investment grade and below investment grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage backed, government issued, domestic and international securities.The fund may also invest in the securities of other investment companies including exchange-traded funds (ETFs) and may make direct investments in other types of investments. See “Other Permitted Investments of the Fund of Funds.”The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests.Use of Hedging and Other Strategic Transactions.

The Lifestyle Growth PS Series, Lifestyle Moderate PS Series, Lifestyle Balanced PS Series and Lifestyle Conservative PS Series (collectively, the “JHVIT Lifestyle PS Series”) and the Bond PS Series are offered only in connection with specific guaranteed benefits under variable annuity contracts (the “Contracts”) issued by John Hancock Life Insurance Company (U.S.A.) and John Hancock Life Insurance Company of New York (collectively, the “John Hancock Issuers”). The Contracts provide that the John Hancock Issuers can automatically transfer contract value between the Lifestyles PS Series and the Bond PS Series through a non-discretionary, systematic mathematical process. The purpose of these transfers is to attempt to protect contract value from declines due to market volatility, and thereby limit the John Hancock Issuers’ exposure to risk on certain guaranteed benefits under the Contracts. The timing and amount of any transfer of contract value under the John Hancock Issuers’ process will depend on several factors including market movements. In general, the higher the equity component of a JHVIT Lifestyle PS Series, the more likely that contract value will be reallocated from the JHVIT Lifestyle PS Series to the Bond PS Series when equity markets fall. These asset flows may negatively affect the performance of an underlying fund in which the JHVIT Lifestyle PS Series invests by increasing the underlying fund’s transaction costs and causing it to purchase or sell securities when it would not normally do so. It could be particularly disadvantageous for the underlying fund if it experiences outflows and needs to sell securities at a time of volatility in the markets, when values could be falling. Because the JHVIT Lifestyle PS Series bear their proportionate share of the transaction costs of the underlying funds, increased underlying fund expenses may indirectly negatively affect the performance of the JHVIT Lifestyle PS Series.Commodity risk Commodity investments involve the risk of volatile market price fluctuations of commodities resulting from fluctuating demand, supply disruption, speculation and other factors.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful,could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Investment company securities risk The fund bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.Principal Risks of Investing in the Underlying Funds Active management risk The subadviser’s investment strategy may fail to produce the intended result.Convertible securities risk The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In addition, as the market price of the underlying common stock declines below the conversion price, the price of the convertible security tends to be increasingly influenced more by the yield of the convertible security.Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract spot transaction, currency forwards, currency options or other over-the-counter derivatives contracts, or a borrower of a fund’s securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund’s share price and income level.Equity securities risk The value of a company’s equity securities is subject to changes in the company’s financial condition, and overall market and economic conditions. The securities of growth companies are subject to greater price fluctuations than other types of stocks because their market prices tend to place greater emphasis on future earnings expectations. The securities of value companies are subject to the risk that the companies may not overcome the adverse business developments or other factors causing their securities to be underpriced or that the market may never come to recognize their fundamental value.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments.Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments. Investments in emerging-market countries are subject to greater levels of foreign investment risk.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Industry or sector risk Because the fund may focus on one or more industry or sector of the economy, its performance depends in large part on the performance of those sectors or industries. As a result, the value of your investment may fluctuate more widely than it would in a fund that is diversified across industries and sectors.Initial public offerings risk IPO shares may have a magnified impact on fund performance and are frequently volatile in price. They can be held for a short period of time causing an increase in portfolio turnover.Issuer risk An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by the fund could default or have its credit rating downgraded.Large company risk Large-capitalization stocks as a group could fall out of favor with the market, causing the fund to underperform investments that focus on small- or medium- capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price.Lower-rated fixed-income securities risk and high-yield fixed-income securities Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as junk bonds) are subject to greater credit-quality risk and risk of default than higher-rated fixed-income securities. These securities may be considered speculative and the value of these securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market or economic developments and can be difficult to resell.Medium and smaller company risk The prices of medium and smaller company stocks can change more frequently and dramatically than those of large company stocks. For purposes of the fund’s investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company’s securities. Market capitalizations of companies change over time.Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.Non-diversified risk Overall risk can be reduced by investing in securities from a diversified pool of issuers, while overall risk is increased by investing in securities of a small number of issuers.Short sales risk Short sales involve costs and risk. The fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

At the discretion of the subadviser, the Equity Allocation may also include direct investments in equity securities and the Fixed Income Allocation may also include direct investments in fixed-income securities. The subadviser may also determine in light of market or economic conditions that the normal percentage limitations should be exceeded to protect the fund or achieve its objective.Within the prescribed percentage allocation, the subadviser selects the percentage level to be maintained in specific underlying funds. These allocations may be changed at any time by the subadviser.The fund may invest in various underlying funds that as a group hold a wide range of equity type securities in their funds. These include small-, mid- and large-capitalization stocks, domestic and foreign securities (including emerging market securities) and sector holdings such as utilities and science and technology stocks. Each of these underlying funds has its own investment strategy which, for example, may focus on growth stocks or value stocks or may employ a strategy combining growth and income stocks and/or may invest in derivatives such as options on securities and futures contracts. The fund may also invest in underlying funds that purchase futures contracts on equity markets.Certain of these underlying funds focus their investment strategy on fixed-income securities, which may include investment grade and below investment grade debt securities with maturities that range from short to longer term. The fixed-income underlying funds collectively hold various types of debt instruments such as corporate bonds and mortgage backed, government issued, domestic and international securities.The fund may also invest in the securities of other investment companies including exchange-traded funds (ETFs) and may make direct investments in other types of investments. See “Other Permitted Investments of the Fund of Funds.”The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests.Use of Hedging and Other Strategic Transactions.

The Lifestyle Growth PS Series, Lifestyle Moderate PS Series, Lifestyle Balanced PS Series and Lifestyle Conservative PS Series (collectively, the “JHVIT Lifestyle PS Series”) and the Bond PS Series are offered only in connection with specific guaranteed benefits under variable annuity contracts (the “Contracts”) issued by John Hancock Life Insurance Company (U.S.A.) and John Hancock Life Insurance Company of New York (collectively, the “John Hancock Issuers”). The Contracts provide that the John Hancock Issuers can automatically transfer contract value between the Lifestyles PS Series and the Bond PS Series through a non-discretionary, systematic mathematical process. The purpose of these transfers is to attempt to protect contract value from declines due to market volatility, and thereby limit the John Hancock Issuers’ exposure to risk on certain guaranteed benefits under the Contracts. The timing and amount of any transfer of contract value under the John Hancock Issuers’ process will depend on several factors including market movements. In general, the higher the equity component of a JHVIT Lifestyle PS Series, the more likely that contract value will be reallocated from the JHVIT Lifestyle PS Series to the Bond PS Series when equity markets fall. These asset flows may negatively affect the performance of an underlying fund in which the JHVIT Lifestyle PS Series invests by increasing the underlying fund’s transaction costs and causing it to purchase or sell securities when it would not normally do so. It could be particularly disadvantageous for the underlying fund if it experiences outflows and needs to sell securities at a time of volatility in the markets, when values could be falling. Because the JHVIT Lifestyle PS Series bear their proportionate share of the transaction costs of the underlying funds, increased underlying fund expenses may indirectly negatively affect the performance of the JHVIT Lifestyle PS Series.Commodity risk Commodity investments involve the risk of volatile market price fluctuations of commodities resulting from fluctuating demand, supply disruption, speculation and other factors.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Investment company securities risk The fund bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.Principal Risks of Investing in the Underlying FundsActive management risk The subadviser’s investment strategy may fail to produce the intended result.Convertible securities risk The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In addition, as the market price of the underlying common stock declines below the conversion price, the price of the convertible security tends to be increasingly influenced more by the yield of the convertible security.Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract spot transaction, currency forwards, currency options or other over-the-counter derivatives contracts, or a borrower of a fund’s securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund’s share price and income level.Equity securities risk The value of a company’s equity securities is subject to changes in the company’s financial condition, and overall market and economic conditions. The securities of growth companies are subject to greater price fluctuations than other types of stocks because their market prices tend to place greater emphasis on future earnings expectations. The securities of value companies are subject to the risk that the companies may not overcome the adverse business developments or other factors causing their securities to be underpriced or that the market may never come to recognize their fundamental value.Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments.Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments. Investments in emerging-market countries are subject to greater levels of foreign investment risk.Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price.Industry or sector risk Because the fund may focus on one or more industry or sector of the economy, its performance depends in large part on the performance of those sectors or industries. As a result, the value of your investment may fluctuate more widely than it would in a fund that is diversified across industries and sectors.Initial public offerings risk IPO shares may have a magnified impact on fund performance and are frequently volatile in price. They can be held for a short period of time causing an increase in portfolio turnover.Issuer risk An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by the fund could default or have its credit rating downgraded.Large company risk Large-capitalization stocks as a group could fall out of favor with the market, causing the fund to underperform investments that focus on small- or medium- capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price.Lower-rated fixed-income securities risk and high-yield securities risk Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as junk bonds) are subject to greater credit-quality risk and risk of default than higher-rated fixed-income securities. These securities may be considered speculative and the value of these securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market or economic developments and can be difficult to resell.Medium and smaller company risk The prices of medium and smaller company stocks can change more frequently and dramatically than those of large company stocks. For purposes of the fund’s investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company’s securities. Market capitalizations of companies change over time.Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.Non-diversified risk Overall risk can be reduced by investing in securities from a diversified pool of issuers, while overall risk is increased by investing in securities of a small number of issuers.Short sales risk Short sales involve costs and risk. The fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
