(Active Bond Trust)

Investment Objective

To seek income and capital appreciation.

Fees and Expenses

This table describes the fees and expenses that you may pay if shares of the fund are held by separate accounts of certain John Hancock insurance companies that fund variable annuity and variable life insurance contracts. They are based on expenses incurred during the fund's most recent fiscal year expressed as a percentage of the fund's average net assets during the year. In subsequent periods, the fund's expense ratio may increase due to decreases in fund assets attributable to redemptions and declines in portfolio valuation. The fees and expenses do not reflect fees and expenses of any separate account that may use the fund as its underlying investment medium and would be higher if they did.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses (Active Bond Trust)		Series I	Series II	NAV
Management fee		0.60%	0.60%	0.60%
Distribution and service (12b-1) fees		0.05%	0.25%	none
Other Expenses		0.04%	0.04%	0.04%
Acquired fund fees and expenses	[1]	0.02%	0.02%	0.02%
Total annual fund operating expenses		0.71%	0.91%	0.66%

Examples. The examples are intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The examples assume that $10,000 is invested in the fund for the periods indicated and then all shares are redeemed at the end of those periods. The examples also assume that the investment has a 5% return each year and that the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (Active Bond Trust) (USD $)	1 Year	3 Years	5 Years	10 Years
Series I	73	227	395	883
Series II	93	290	504	1,120
NAV	67	211	368	822

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 86% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a diversified mix of debt securities and instruments. The fund seeks to invest its assets in debt securities and instruments with an average duration of between 4 to 6 years, however, there is no limit on the fund's average maturity. As part of its investment strategy, the fund may invest in mortgage-backed securities to a significant extent.

Eligible investments include, but are not limited to:

• U.S. Treasury and agency securities;

• Asset-backed securities and mortgage-backed securities, both investment grade and non-investment grade, including mortgage pass-through securities, commercial mortgage-backed securities ("CMBS") and collateralized mortgage obligations ("CMOs");

• Corporate bonds, both U.S. and foreign, and without any limit on credit quality; and

• Foreign government and agency securities.

The fund may invest in asset-backed securities rated, at the time of purchase, less than A (but not rated lower than B by Standard & Poor's Ratings Services ("S&P") or Moody's Investors Service ("Moody's"). Each subadvisor uses proprietary research and economic and industry analysis to identify specific bonds, bond sectors and industries that are attractively priced. Due to this process, the fund may have a higher than average portfolio turnover ratio, which may increase expenses and affect performance results.

The foreign securities in which the fund invests may be denominated in U.S. dollars or foreign currency.

The fund employs a multi-manager approach with two subadvisors, Declaration Management & Research LLC ("Declaration") and John Hancock Asset Management a division of Manulife Asset Management (US) LLC ("John Hancock Asset Management"), each of which employs its own investment approach and independently manages its portion of the fund. The fund will be rebalanced periodically so that the subadvisors manage the following portions of the fund:

50%* Declaration

50%* John Hancock Asset Management

*Percentages are approximate. Since the fund is only rebalanced periodically, the actual portion of the fund managed by each subadvisor will vary.

This allocation methodology may change in the future.

Declaration

Declaration uses a combination of proprietary research and quantitative tools and seeks to identify bonds and bond sectors that are attractively priced based upon market fundamentals and technical factors. Declaration opportunistically emphasizes bonds with yields in excess of U.S. Treasury securities.

This portion of the fund normally has no more than 10% of its total assets in high yield bonds ("junk bonds") and normally invests in foreign securities only if U.S. dollar-denominated. This portion of the fund normally has an average credit rating of "A" or "AA."

John Hancock Asset Management

John Hancock Asset Management uses proprietary research to identify specific bond sectors, industries and bonds that are attractively priced. John Hancock Asset Management tries to anticipate shifts in the business cycle, using economic and industry analysis to determine which sectors and industries might benefit over the next 12 months.

This portion of the fund normally has no more than 25% of its total assets in high yield bonds (sometimes referred to as "junk bonds") and may invest in both U.S. dollar-denominated and foreign currency-denominated foreign securities. This portion of the fund normally has an average credit rating of "A" or "AA."

Under normal circumstances, no more than 15% of the total assets of the portion of the fund managed by John Hancock Asset Management will be invested in asset-backed securities rated lower than A by both rating agencies.

Use of Hedging and Other Strategic Transactions. The fund is authorized to use all of the various investment strategies referred to under "Additional Information About the Funds' Principal Risks —Hedging, derivatives and other strategic trans actions risk" including, but not limited to, U.S. Treasury futures and options, index derivatives, credit default swaps and forwards.

Principal Risks of Investing in the Fund

The fund is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the fund include:

Active management risk The subadvisor's investment strategy may fail to produce the intended result.

Changing distribution levels risk The distribution amounts paid by the fund generally depend on the amount of income and/or dividends received by the fund's investments. As a result of market, interest rate and other circumstances, the amount of cash available for distribution by the fund and the fund's distribution rate may vary or decline. The risk of such variability is accentuated in currently prevailing market and interest rate circumstances.

Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract or a borrower of a fund's securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations. 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.

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. The use of derivative instruments 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. The following is a list of certain derivatives and other strategic transactions in which the fund may invest and the main risks associated with each of them:

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 options. Counterparty risk does not apply to exchange-traded options.

Swaps Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, settlement risk, risk of default of the underlying reference obligation and risk of disproportionate loss are the principal risks of engaging in transactions involving swaps.

Swaptions 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 swaptions.

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.

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.

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.

Inverse interest-only securities Inverse interest-only securities that are mortgage-backed securities are subject to the same risks as other mortgage-backed securities. In addition, the coupon on an inverse interest-only security can be extremely sensitive to changes in prevailing interest rates.

TBA mortgage contracts TBA mortgage contracts involve a risk of loss if the value of the underlying security to be purchased declines prior to delivery date. The yield obtained for such securities may be higher or lower than yields available in the market on delivery date.

Past Performance

The following information provides some indication of the risks of investing in the fund by showing changes in performance from year to year and by showing how average annual returns for specified periods compare with those of a broad measure of market performance. For periods prior to the inception of the fund, performance shown for each share class is the actual performance of the sole share class of the fund's predecessor fund. This pre-inception performance for each of the Series I and Series II share classes has not been adjusted to reflect the Rule 12b-1 fees of that class and would be lower if it did. The performance information below does not reflect fees and expenses of any variable insurance contract which may use JHVIT as its underlying investment medium. If such fees and expenses had been reflected, performance would be lower. The past performance of the fund is not necessarily an indication of how the fund will perform in the future.
