EXPENSE EXAMPLE

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example - (John Hancock International Small Company Fund)	1 Year	3 Years	5 Years	10 Years
Class R6 | USD ($)	109	340	590	1,306

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 and may result in higher taxes when fund shares are held in a taxable account. 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 12% 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 securities of small-cap companies in the particular markets in which the fund invests. As of October 31, 2016, the maximum market capitalization range of eligible companies for purchase was approximately $2.0 billion to $5.7 billion, depending on the country. The fund will primarily invest in a broad and diverse group of equity securities of foreign small companies of developed markets, but may also hold equity securities of companies located in emerging markets.

The fund invests its assets in securities listed on bona fide securities exchanges or traded on the over-the-counter markets, including dual-listed securities, either within or outside the issuer's domicile country.

The manager measures company size on a country- or region-specific basis and based primarily on market capitalization. In the countries or regions authorized for investment, the manager first ranks eligible companies' based on market capitalizations and then determines the universe of eligible stocks by defining the maximum market capitalization of a small company that may be purchased by the fund with respect to each country or region. These thresholds will vary based on market conditions. The fund intends to use a market-capitalization-weighted approach in seeking to set country weights based on the relative market capitalizations of eligible small companies within each country (see below). Weightings of certain countries may vary from their weightings in international indexes.

The fund may also use derivatives such as futures contracts and options on futures contracts to adjust market exposure based on expected cash inflows to or outflows from the fund. Futures contracts and options on futures contracts may be for foreign or U.S. equity securities and indexes. The fund may also enter into forward currency contracts to facilitate settlement of equity purchases of foreign securities, repatriation of foreign currency balances, or currency exchange. In addition to cash, money market instruments, and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage cash pending investment, to maintain liquidity to pay redemptions, to make other anticipated cash payments, or for other purposes. Investments in money market funds may involve a duplication of certain fees and expenses.

The fund does not seek current income as an investment objective and investments will not be based on an issuer's dividend payment policy or record, although many of the companies in which the fund invests do pay dividends.

The manager may, in its discretion, invest in countries authorized by its Investment Committee, depending upon factors such as asset growth in the fund and market characteristics. Other countries may be authorized for investment in the future, and the fund may continue to hold investments in countries previously but not currently authorized. The fund may focus its investments in a particular sector or sectors of the economy.

Market-capitalization-weighted approach

The fund uses market capitalization weighting to determine individual security weights and, where applicable, country or region weights. Market-capitalization weighting means each security is generally purchased based on the issuer's relative market capitalization. Market-capitalization weighting will be adjusted by the manager for a variety of factors, including free float, momentum, trading strategies, liquidity management, profitability, and market conditions, among others. The manager may deviate from market-capitalization weighting to limit or fix the exposure of the fund to a particular country or issuer to a maximum proportion of fund assets and may exclude the stock of a company that meets applicable market-capitalization criteria at its discretion. These adjustments will result in a deviation from traditional market-capitalization weighting.

Country weights may be based on the total market capitalization of companies within each country and may take into consideration the free float of companies within a country or whether these companies are eligible to be purchased for the particular strategy. In addition, to maintain a satisfactory level of diversification, the Investment Committee may limit or adjust the exposure to a particular country or region to a maximum proportion of the assets of that vehicle. Country weights may also deviate from target weights due to general day-to-day trading patterns and price movements.

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.

During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.

The fund's main risks are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.

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.

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.

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.

Foreign securities risk. Less information may be publicly available regarding foreign 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.

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, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.

Investment company securities risk. A fund bears underlying fund fees and expenses indirectly.

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.

Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.

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.

A note on performance

Class NAV shares commenced operations on April 28, 2006. Because Class R6 shares of the fund had not commenced operations as of the date of this prospectus, the returns shown are those of Class NAV shares. Returns for Class R6 shares would have been substantially similar to returns of Class NAV shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Please note that after-tax returns reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan.
