(Mid Cap Stock Trust)

Investment Objective

To seek long-term growth of capital.

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 (Mid Cap Stock Trust)	Series I	Series II	NAV
Management fee	0.84%	0.84%	0.84%
Distribution and service (12b-1) fees	0.05%	0.25%	none
Other Expenses	0.04%	0.04%	0.04%
Total annual fund operating expenses	0.93%	1.13%	0.88%

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 (Mid Cap Stock Trust) (USD $)	1 Year	3 Years	5 Years	10 Years
Series I	95	296	515	1,143
Series II	115	359	622	1,375
NAV	90	281	488	1,084

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 115% 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 equity securities of medium-sized companies with significant capital appreciation potential. For the fund,"medium-sized companies" are those with market capitalizations within the collective market capitalization range of companies represented in either the Russell Midcap Index ($315 million to $42 billion as of February 28, 2013) or the S&P MidCap 400 Index ($322 million to $16.2 billion as of February 28, 2013).

The subadvisor's investment approach is based primarily on proprietary fundamental analysis. Fundamental analysis involves the assessment of a company through such factors as its business environment, management, balance sheet, income statement, anticipated earnings, revenues and other related measures of value. In analyzing companies for investment, the subadvisor looks for, among other things, a strong balance sheet, strong earnings growth, attractive industry dynamics, strong competitive advantages (e.g., strong management teams), and attractive relative value within the context of a security's primary trading market. Securities are sold when the investment has achieved its intended purpose, or because it is no longer considered attractive. The fund may invest up to 25% of its total assets in foreign securities, including emerging market securities.

The fund's investment process may, at times, result in a higher than average portfolio turnover ratio and increased trading expenses.

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.

Emerging markets risk The risks of investing in foreign securities are greater for investments in emerging markets. Emerging market countries may experience higher inflation, interest rates and unemployment as well as greater social, economic, regulatory and political uncertainties than more developed countries.

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.

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.

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.

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.

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. Unless all share classes shown in the table have the same inception date, performance shown for periods prior to the inception date of a class is the performance of the fund's oldest share class. This pre-inception performance, with respect to any other share class of the fund, has not been adjusted to reflect the 12b-1 fees of that class. As a result, the pre-inception performance shown for a share class other than the oldest share class may be higher or lower than it would be if adjusted to reflect the 12b-1 fees of the class. 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.
