Investment objective

To seek long-term growth of capital.

Fees and expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. The fees and expenses do not reflect fees and expenses of any variable insurance or variable annuities contract that may use the fund as its underlying investment option 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)	Series I	Series II	Series NAV
Management fee	0.67	0.67	0.67
Distribution and service (Rule 12b-1) fees	0.05	0.25	0.00
Other expenses	0.12	0.12	0.12
Total annual fund operating expenses	0.84	1.04	0.79

Expense example

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. The expense example does not reflect fees and expenses of any variable insurance contract that may use the fund as its underlying investment option and would be higher if they did. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 

Expenses ($)	Series I	Series II	Series NAV
1 year	86	106	81
3 years	268	331	252
5 years	466	574	439
10 years	1,037	1,271	978

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 72% of the average value of its portfolio.

Principal investment strategies

The Board of Trustees can change the fund's investment objective and strategies without shareholder approval.

The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of equity and equity-related securities issued by non-U.S. companies of any capitalization size. The fund may invest in all types of equity and equity-related securities, including, without limitation, exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, participatory notes, limited partnership interests, shares of other investment companies (including exchange-traded funds (ETFs)), real estate investment trusts (REITs), and equity participations. An equity participation is a type of loan that gives the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock, or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula.

The fund defines non-U.S. companies as companies: (i) that are organized under the laws of a foreign country; (ii) whose principal trading market is in a foreign country; or (iii) that have a majority of their assets, or that derive a significant portion of their revenue or profits, from businesses, investments, or sales outside of the United States. The fund primarily will be invested in issuers located in countries with developed securities markets, but may also invest in issuers located in emerging and frontier markets.

The fund may invest in securities denominated in the currencies of a variety of developed, emerging and frontier market countries.

The fund generally invests in the equity securities of issuers believed by the manager to be undervalued in the marketplace, focusing on issuers that combine attractive valuations with catalysts for change. The manager applies a bottom-up stock selection process (i.e., one that focuses primarily on issuer specific factors) in managing the fund, using a combination of fundamental and quantitative analysis. In selecting investments for the fund, the manager considers various factors, such as price-to-book value, price-to-sales and earnings ratios, dividend yields, strength of management, and cash flow to identify securities that are trading at a price that appears to be lower than the issuer's inherent value.

The fund may (but is not required to) invest in derivatives, including put and call options, futures, forward contracts, and swaps, in lieu of investing directly in a security, currency or instrument, for hedging and nonhedging purposes, including reducing risk, obtaining efficient market exposure, and/or enhancing investment returns.

The fund may invest up to 15% of its net assets in illiquid securities, including securities that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

The fund may participate as a purchaser in Initial Public Offerings (IPOs). An IPO is a company's first offering of stock to the public. The fund may also seek to increase its income by lending portfolio securities.

The manager will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the manager constantly monitors and adjusts as appropriate.

The fund may invest in cash or money market instruments for the purpose of meeting redemption requests or making other anticipated cash payments.

Principal risks

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.

The fund's main risks are listed below in alphabetical order, not in order of importance. Before investing, be sure to read the additional descriptions of these risks beginning on page 257 of the prospectus.

Cash and cash equivalents risk. Under certain market conditions, such as during a rising stock market, rising interest rate or rising credit spread markets, the use of cash and/or cash equivalents, including money market instruments, could have a negative effect on the fund's ability to achieve its investment objective and may negatively impact the fund's performance.

Credit and counterparty risk. The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations.

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.

Equity securities risk. The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.

Exchange-traded fund (ETF) investment risk. The risks of owning shares of an ETF include the risks of owning the underlying securities the ETF holds. Lack of liquidity in an ETF could result in the ETF being more volatile than its underlying securities. An ETF's shares could trade at a significant premium or discount to its net asset value (NAV). A fund bears ETF fees and expenses indirectly.

Foreign securities risk. Less information may be publicly available regarding foreign issuers, including foreign government issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.

Frontier-market risk. Frontier-market countries generally have smaller economies and less-developed capital markets and political systems than traditional emerging-market countries, which magnifies emerging-market risks.

Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, swaps, equity-linked notes (equity-linked notes generally reflect the risks associated with their underlying securities, depend on the credit of the note's issuer, may be privately placed, and may have a limited secondary market), and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.

Illiquid and restricted securities risk. Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.

Initial public offerings (IPOs) risk. IPO share prices are frequently volatile and may significantly impact fund performance.

Investment company securities risk. Fund shareholders indirectly bear their proportionate share of the expenses of any investment company in which the fund invests. The total return on such investments will be reduced by the operating expenses and fees of such other investment companies, including advisory fees.

Large company risk. Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.

Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.

Operational and cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.

Participatory notes risk. Participatory notes (p-notes) represent interests in securities listed on certain foreign exchanges. Due to transaction costs and other expenses, p-notes will not replicate exactly the performance of their underlying securities. P-notes are general unsecured contractual obligations of the financial institutions issuing the notes and are subject to liquidity risk and a high degree of counterparty risk.

Preferred and convertible securities risk. Preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock's value can depend heavily upon the underlying common stock's value.

Real estate investment trust (REIT) risk. REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.

Securities lending risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral if the borrower fails financially. The fund could also lose money if the value of the collateral decreases.

Small and mid-sized company risk. Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.

Value investment style risk. Value securities may underperform the market as a whole, which may cause value-oriented funds to underperform equity funds with other investment strategies. Securities the manager believes are undervalued may never perform as expected.

Warrants risk. The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.

Past performance

The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based securities market index. Past performance does not indicate future results. All figures assume dividend reinvestment. The performance information below does not

reflect fees and expenses of any variable insurance contract which may use JHVIT as its underlying investment option. If such fees and expenses had been reflected, performance would be lower.

A note on performance

Purchase and redemption of fund shares

Shares of the fund are not sold directly to the public but generally may be sold only to insurance companies and their separate accounts as the underlying investment options for variable annuity and variable life insurance contracts issued by such companies, to certain entities affiliated with the insurance companies, to those funds of JHVIT that operate as funds of funds and invest in other funds and to certain qualified retirement plans (qualified plans).

Shares of the fund are offered continuously, without sales charge, and are sold and redeemed each business day (which typically is any day the New York Stock Exchange is open) at a price equal to their net asset value (NAV) determined for that business day as set forth under "Valuation of shares" in this prospectus. The Portfolio does not have minimum initial or subsequent investment requirements. Payment for shares redeemed will generally be made within seven days after receipt of a proper notice of redemption.

Taxes

Because shares of the fund may be purchased only through variable insurance contracts and qualified plans, it is expected that any dividends or capital gains distributions made by the fund will be exempt from current federal taxation if left to accumulate within the variable contract or qualified plan. Holders of variable insurance contracts should consult the prospectuses of their respective contracts for information on the federal income tax consequences to such holders.

Compensation of financial intermediaries

The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The distributors of these contracts, the insurance companies that issue the contracts and their related companies (Related Parties), may pay compensation to broker-dealers and other intermediaries for distribution and other services and may enter into revenue sharing arrangements with certain intermediaries. The fund pays fees to the Related Parties for management, distribution and other services. Payments by insurance and related companies to intermediaries may create a conflict of interest by influencing them and their salespersons to recommend such contracts over other investments. Ask your salesperson or visit your financial intermediary's website for more information. In addition, payments by the funds to Related Parties may be a factor that an insurance company considers in including the funds as underlying investment options in variable insurance contracts. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.
