(International Small Company Fund - Class A) | (International Small Company Fund)

Investment objective

To seek long-term capital appreciation.

Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts on Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the John Hancock family of funds. More information about these and other discounts is available on pages 13 to 14 of the prospectus under "Sales charge reductions and waivers" or pages 82 to 86 of the fund's statement of additional information under "Initial Sales Charge on Class A Shares."

Shareholder fees (%) (fees paid directly from your investment)

Shareholder Fees (International Small Company Fund) (USD $)		Class A (International Small Company Fund - Class A)
Maximum front-end sales charge (load) on purchases as a % of purchase price		5.00%
Maximum deferred sales charge (load) as a % of purchase or sale price, whichever is less	[1]	1.00%
Small account fee (for fund account balances under $1,000)		20

Annual fund operating expenses (%) (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses (International Small Company Fund)		Class A (International Small Company Fund - Class A)
Management fee		0.95%
Distribution and service (12b-1) fees		0.30%
Other expenses	[1]	0.40%
Total annual fund operating expenses		1.65%
Contractual expense reimbursement	[2]	(0.02%)
Total annual fund operating expenses after expense reimbursements		1.63%

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 in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes 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:

Sold

Expense Example (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class A (International Small Company Fund - Class A)	657	992	1,350	2,354

Kept

Expense Example, No Redemption (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class A (International Small Company Fund - Class A)	657	992	1,350	2,354

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market Capitalization Weighted Approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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 performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/FundPerformance, or by calling Signature Services at 1-800-225-5291, Monday–Thursday between 8:00 A.M. and 7:00 P.M. and on Fridays between 8:00 A.M. and 6:00 P.M., Eastern Time.

Calendar year total returns These do not include sales charges and would have been lower if they did.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns They reflect the highest individual federal marginal income-tax rates 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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class A shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class A shares. Returns for Class A shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Calendar year total returns — Class A (%)

Year-to-date total return The fund's total return for the three months ended March 31, 2013 was 6.26%.

Best quarter:  Q2 '09,  31.60%

Worst quarter: Q3 '08, -22.71%

Average annual total returns (%) As of 12-31-12

[1] "Other expenses" have been estimated for the first year of operations of the fund's Class A shares.

[2] The advisor has contractually agreed to waive all or a portion of its management fee and/or reimburse or pay operating expenses of the fund to the extent necessary to maintain the fund's total operating expenses at 1.63% for Class A shares, excluding certain expenses such as taxes, brokerage commissions, interest expense, litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, acquired fund fees and expenses and short dividend expense. The current expense limitation agreement expires on December 31, 2014, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor may recapture operating expenses reimbursed or fees waived, for a period of three years following the beginning of the month in which such reimbursement or waivers occurred to the extent that the fund is below its expense limitation during this period.

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 48% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/FundPerformance, or by calling Signature Services at 1-800-225-5291, Monday–Thursday between 8:00 A.M. and 7:00 P.M. and on Fridays between 8:00 A.M. and 6:00 P.M., Eastern Time.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class C shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class C shares. Returns for Class C shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Short Duration Credit Opportunities Fund) (Short Duration Credit Opportunities Fund - Class R3 and Class R5) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R3	1,552	4,142	6,173	9,531
Class R5	1,500	4,029	6,038	9,436

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 60% of the average value of its portfolio.

Principal investment strategies

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R3 and Class R5 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R3 and Class R5 shares, as applicable.

Expense Example (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class I (International Small Company Fund - Class I)	125	394	684	1,508

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 following is a list of certain derivatives and other strategic transactions in which the fund intends to invest and the main risks associated with each of them:

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.

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.

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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class I shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class I shares. Returns for Class I shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

The current expense limitation agreement expires on December 31, 2014, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor may recapture operating expenses reimbursed or fees waived, for a period of three years following the beginning of the month in which such reimbursement or waivers occurred to the extent that the fund is below its expense limitation during this period.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Global High Yield Fund) (Global High Yield Fund - Class R3 and R5) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R3	1,565	4,170	6,205	9,553
Class R5	1,513	4,057	6,072	9,461

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 48% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, most business days.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R3 and Class R5 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R3 and Class R5 shares, as applicable. Returns for Class R3 and Class R5 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 60% of the average value of its portfolio.

Principal investment strategies

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/FundPerformance, or by calling Signature Services at 1-800-225-5291, Monday–Thursday between 8:00 A.M. and 7:00 P.M. and on Fridays between 8:00 A.M. and 6:00 P.M., Eastern Time.

Calendar year total returns These do not include sales charges and would have been lower if they did.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns They reflect the highest individual federal marginal income tax rates 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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to this date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class C shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class C shares. Returns for Class C shares would have been substantially similar to returns of Class A because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Calendar year total returns — Class C (%)

Year-to-date total return The fund's total return for the three months ended March 31, 2013 was  -3.27%.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Short Duration Credit Opportunities Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R6 (Short Duration Credit Opportunities Fund - Class R6)	1,496	4,019	6,027	9,428

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 60% of the average value of its portfolio.

Principal investment strategies

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/ return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares.

Returns for Class R1, Class R2 and Class R4 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Global Absolute Return Strategies Fund) (Global Absolute Return Strategies Fund - Class R3 and Class R5) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R3	1,610	4,267	6,319	9,627
Class R5	1,559	4,157	6,190	9,543

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 the period from December 19, 2011 (commencement of operations) through July 31, 2012, the fund's portfolio turnover rate was 33% of the average value of its portfolio.

Principal investment strategies

The fund has a broad investment mandate that permits it to use an extensive range of investment strategies and to invest in a wide spectrum of equity and fixed-income securities, as well as derivative instruments, in pursuing its investment objective.

The fund invests in equity securities of U.S. and foreign companies of various market capitalizations. The fund also invests in fixed-income securities, which are not subject to any credit rating or maturity limitations, issued by companies and government and supranational entities around the world, including high-yield non-investment-grade securities (i.e., junk bonds). The fund may invest in emerging as well as developed markets and may invest a significant portion of its assets in the securities of companies in particular economic sectors.

The fund also may invest extensively in derivative instruments, which are generally financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate, or index, and may relate to equity securities, fixed-income securities, interest rates, total return rates, currencies or currency exchange rates, and related indexes. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in or exposed to obligations of issuers or obligors located outside of the United States.

The subadvisor employs a "global multi-asset strategy" and seeks to achieve total return by delivering a diversified global portfolio that makes use of multiple strategies across various asset classes. It aims to exploit market cyclicality and a diverse array of inefficiencies across and within global markets to maximize risk adjusted absolute return by investing in listed equity, equity-related and debt securities, and derivatives or other instruments, both for investment and hedging purposes. The fund invests in derivative instruments (which will be used routinely), including futures, options, swaps (including credit default swaps and variance swaps), and foreign currency forward contracts.

The subadvisor manages the fund's investment strategies dynamically over time, and will actively modify investment strategies and develop new strategies in response to additional research, changing market conditions, or other factors. The fund's strategies seek to deliver returns commensurate with reasonable levels of risk and tangible diversification benefits, while having both sufficient liquidity and capacity to benefit the fund in a significant way. The fund also may hold cash or invest its cash balances in cash equivalents and short-term investments, including money market funds, in order to cover the derivative transactions or otherwise in its discretion.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. In addition, although the subadvisor aims to maximize absolute return, there is no guarantee that the fund will generate positive returns. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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 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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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. 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.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Calendar year total returns Calendar year total returns are shown only for Class R1 shares and would be different for other share classes.

Average annual total returns Performance of a broad-based market index is included for comparison. The MSCI World Index shows how the fund's performance compares with the returns of similar investments.

After-tax returns These are shown only for Class R3 shares and would be different for other classes. They reflect the highest individual federal marginal income tax rates 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.

Bank of America Merrill Lynch US Dollar 1-Month LIBID Average Index tracks the performance of a synthetic asset paying LIBID (London Interbank Bid Rate) to a stated maturity.

MSCI World Index is a free float-adjusted market capitalization weighted index that is designed to measure equity market performance of developed markets.

Because Class R3 and Class R5 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R3 and Class R5 shares, as applicable. Returns for Class R3 and Class R5 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Growth Opportunities Fund) (International Growth Opportunities Fund - Class R1, Class R2 and R4) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R1	1,586	4,216	6,259	9,589
Class R2	1,565	4,170	6,205	9,553
Class R4	1,552	4,142	6,173	9,531

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

Continental Europe European securities may be affected significantly by economic, regulatory or political developments affecting European issuers. All countries in Europe may be significantly affected by fiscal and monetary controls implemented by the European Economic and Monetary Union. Eastern European markets are relatively undeveloped and may be particularly sensitive to economic and political events affecting those countries.

Japan A fund that holds Japanese securities may be affected significantly by economic, regulatory or political developments affecting Japanese issuers. The Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect Japanese markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the Japanese securities markets, as well as cross-shareholdings in Japanese companies, may affect trading prices and volumes in these markets.

United Kingdom A fund that holds U.K. securities may be affected significantly by economic, regulatory or political developments affecting U.K. issuers. Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences. Furthermore, the U.K. is closely tied to Continental Europe and may be impacted to a greater extent than other countries by euro common currency economic and political events.

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. 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.

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.

Medium company risk The prices of medium 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.

Small company risk Stocks of smaller companies are more volatile than stocks of larger companies. 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

This section normally shows how the fund's total returns have varied from year to year, along with a broad-based market index for reference. Because the fund had less than a full calendar year of operations as of the date of this prospectus, there is no past performance to report.

The example assumes a 5% average annual return. The example assumes 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:

Class R1	1,573	4,188	6,227	9,568
Class R2	1,552	4,142	6,173	9,531
Class R4	1,539	4,114	6,139	9,508

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 48% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds.

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Past performance

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R1, Class R2 and Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R1, Class R2 and Class R4 shares, as applicable. Returns for Class R1, Class R2 and Class R4 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Global Absolute Return Strategies Fund) (Global Absolute Return Strategies Fund - Class R1 and Class R4) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R1	1,618	4,285	6,339	9,640
Class R4	1,584	4,212	6,255	9,586

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 the period from December 19, 2011 (commencement of operations) through July 31, 2012, the fund's portfolio turnover rate was 33% of the average value of its portfolio.

Principal investment strategies

The fund has a broad investment mandate that permits it to use an extensive range of investment strategies and to invest in a wide spectrum of equity and fixed-income securities, as well as derivative instruments, in pursuing its investment objective.

The fund invests in equity securities of U.S. and foreign companies of various market capitalizations. The fund also invests in fixed-income securities, which are not subject to any credit rating or maturity limitations, issued by companies and government and supranational entities around the world, including high-yield non-investment-grade securities (i.e., junk bonds). The fund may invest in emerging as well as developed markets and may invest a significant portion of its assets in the securities of companies in particular economic sectors.

The fund also may invest extensively in derivative instruments, which are generally financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate, or index, and may relate to equity securities, fixed-income securities, interest rates, total return rates, currencies or currency exchange rates, and related indexes. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in or exposed to obligations of issuers or obligors located outside of the United States.

The subadvisor employs a "global multi-asset strategy" and seeks to achieve total return by delivering a diversified global portfolio that makes use of multiple strategies across various asset classes. It aims to exploit market cyclicality and a diverse array of inefficiencies across and within global markets to maximize risk adjusted absolute return by investing in listed equity, equity-related and debt securities, and derivatives or other instruments, both for investment and hedging purposes. The fund invests in derivative instruments (which will be used routinely), including futures, options, swaps (including credit default swaps and variance swaps), and foreign currency forward contracts.

The subadvisor manages the fund's investment strategies dynamically over time, and will actively modify investment strategies and develop new strategies in response to additional research, changing market conditions, or other factors. The fund's strategies seek to deliver returns commensurate with reasonable levels of risk and tangible diversification benefits, while having both sufficient liquidity and capacity to benefit the fund in a significant way. The fund also may hold cash or invest its cash balances in cash equivalents and short-term investments, including money market funds, in order to cover the derivative transactions or otherwise in its discretion.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. In addition, although the subadvisor aims to maximize absolute return, there is no guarantee that the fund will generate positive returns. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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 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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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. 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.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Calendar year total returns Calendar year total returns are shown only for Class R1 shares and would be different for other share classes.

Average annual total returns Performance of a broad-based market index is included for comparison. The MSCI World Index shows how the fund's performance compares with the returns of similar investments.

After-tax returns These are shown only for Class R1 shares and would be different for other classes. They reflect the highest individual federal marginal income tax rates 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.

Bank of America Merrill Lynch US Dollar 1-Month LIBID Average Index tracks the performance of a synthetic asset paying LIBID (London Interbank Bid Rate) to a stated maturity.

MSCI World Index is a free float-adjusted market capitalization weighted index that is designed to measure equity market performance of developed markets.

Because Class R1 and Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R1 and Class R4 shares, as applicable. Returns for Class R1 and Class R4 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Calendar year total returns — Class R1 (%)

Year-to-date total return The fund's total return for the three months ended March 31, 2013 was -1.74%.

Best quarter:  Q1 '12,  2.41%

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 in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes 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:

Sold

Class C (International Growth Opportunities Fund - Class C)	1,723	4,294	6,350	9,646

Kept

Expense Example, No Redemption (International Growth Opportunities Fund) (USD $)	1 Year	3 Years	5 Years	10 Years

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

Continental Europe European securities may be affected significantly by economic, regulatory or political developments affecting European issuers. All countries in Europe may be significantly affected by fiscal and monetary controls implemented by the European Economic and Monetary Union. Eastern European markets are relatively undeveloped and may be particularly sensitive to economic and political events affecting those countries.

Japan A fund that holds Japanese securities may be affected significantly by economic, regulatory or political developments affecting Japanese issuers. The Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect Japanese markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the Japanese securities markets, as well as cross-shareholdings in Japanese companies, may affect trading prices and volumes in these markets.

United Kingdom A fund that holds U.K. securities may be affected significantly by economic, regulatory or political developments affecting U.K. issuers. Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences. Furthermore, the U.K. is closely tied to Continental Europe and may be impacted to a greater extent than other countries by euro common currency economic and political events.

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. 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.

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.

Medium company risk The prices of medium 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.

Small company risk Stocks of smaller companies are more volatile than stocks of larger companies. 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

This section normally shows how the fund's total returns have varied from year to year, along with a broad-based market index for reference. Because the fund had less than a full calendar year of operations as of the date of this prospectus, there is no past performance to report.

Investment objective

To seek long-term capital appreciation.

Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder fees (%) (fees paid directly from your investment)

Shareholder Fees (International Growth Opportunities Fund)	Class R6 (International Growth Opportunities Fund - Class R6)
Maximum front-end sales charge (load) on purchases as a % of purchase price	none
Maximum deferred sales charge (load) as a % of purchase or sale price, whichever is less	none

Annual fund operating expenses (%) (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses (International Growth Opportunities Fund)		Class R6 (International Growth Opportunities Fund - Class R6)
Management fee		0.86%
Other expenses	[1]	15.25%
Total annual fund operating expenses		16.11%

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Growth Opportunities Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R6 (International Growth Opportunities Fund - Class R6)	1,522	4,076	6,095	9,477

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Portfolio turnover

The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and 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 performance of the underlying funds and the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 34% of the average value of its portfolio.

Principal investment strategies

The fund will seek to achieve its objective by investing in "alternative asset classes." The fund invests in other funds as well as other types of investments as described below.

The fund will allocate its assets among other funds in the John Hancock Funds complex and other investment companies, including exchange-traded funds (ETFs) (collectively, "Underlying Funds"), that emphasize alternative or non-traditional asset categories or investment strategies such as international small-cap stocks, emerging-market equity, commodities, market neutral (long/short), global real estate, natural resources, TIPS (Treasury Inflation-Protected Securities), global bonds, high yield, bank loans, foreign currency trading strategies, absolute return strategies, managed futures, arbitrage strategies, tactical investment strategies and emerging-market debt. In addition, the fund may also directly invest in exchange-traded notes (ETNs).

The fund may use a portion of its assets to employ a market neutral (long/short) strategy by simultaneously purchasing a security and entering into a short sale on the security.

The fund operates as a fund of funds and may invest in Underlying Funds and in other types of investments as described below. The fund may purchase any Underlying Funds except other funds of funds. When purchasing shares of other John Hancock Funds, the fund only purchases NAV shares (which are not subject to Rule 12b-1 fees).

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 8 of the prospectus.

Risks of investing in the fund of funds

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

Asset allocation risk Although asset allocation among different asset categories generally limits risk and exposure to any one category, the risk remains that the advisor may favor an asset category that performs poorly relative to the other asset categories. To the extent that alternative asset categories underperform the general stock market, the fund would perform poorly relative to a fund invested primarily in the general stock market.

Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.

Exchange-traded notes risk Similar to ETFs, owning an ETN generally reflects the risks of owning the assets that comprise the underlying market benchmark or strategy that the ETN is designed to reflect. ETNs also are subject to issuer and fixed-income risk.

Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.

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.

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.

Risks of investing in the underlying funds

Commodity risk The market price of commodity investments may be volatile due to fluctuating demand, supply disruption, speculation and other factors.

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

Emerging-market 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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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.

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

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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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.

Natural resources risk The natural resources industry can be significantly affected by events relating to international political and economic developments, energy conservation, the success of exploration projects, commodity prices, and taxes and other governmental regulations.

Non-diversified risk Overall risk can be reduced by investing in securities from a diversified pool of issuers and is increased by investing in securities of a small number of issuers. Investments in a non-diversified fund may magnify the fund's losses from adverse events affecting a particular issuer.

Real estate securities risk Investing in securities of companies in the real estate industry subjects a fund to the risks associated with the direct ownership of real estate.

Past performance

The following performance information in the bar chart and table below 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.

Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Average annual total returns Performance of broad-based market indexes is included for comparison.

After-tax returns They reflect the highest individual federal marginal income-tax rates 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.

Performance information prior to December 20, 2010 reflects an allocation to a different mix of underlying funds and would have been different if the fund's investments had been allocated to its current mix of underlying funds.

January 2, 2009 is the inception date for the oldest class of shares, Class A shares. Because Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R4 shares. Returns for Class R4 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

[1] The fund's distributor has contractually agreed to waive 0.10% of Rule 12b-1 fees for Class R4 shares. The current waiver agreement will remain in effect through December 31, 2014, unless renewed by mutual agreement of the fund and the distributor based upon a determination that this is appropriate under the circumstances at that time. Excluding this waiver would result in Rule 12b-1 fees of 0.25%.

[2] "Other expenses" have been estimated for the first year of operations of the fund's Class R4 shares.

[3] "Acquired fund fees and expenses" are based on the indirect net expenses associated with the fund's investments in underlying investment companies. The "Total annual fund operating expenses" shown may not correlate to the fund's ratio of expenses to average net assets shown in the "Financial highlights" section of this prospectus, which do not include "Acquired fund fees and expenses."

[4] The advisor has contractually agreed to reimburse the fund for certain fund expenses (excluding certain expenses such as advisory fees, transfer agent fees and service fees, Rule 12b-1 fees, brokerage commissions, interest expense, blue sky fees, printing and postage, litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, short dividend expense and acquired fund fees and expenses) that exceed 0.04% of the fund's average annual net assets. The current expense limitation agreement expires on December 31, 2014 unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time. The advisor may recapture operating expenses reimbursed or fees waived, for a period of three years following the beginning of the month in which such reimbursement or waivers occurred to the extent that the fund is below its expense limitation during this period.

[5] The advisor has contractually agreed to waive its management fee by 0.10% as a percentage of the fund's average annual net assets.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Global High Yield Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R6 (Global High Yield Fund - Class R6)	1,509	4,048	6,061	9,453

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 48% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/InstitutionalPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Average annual total returns Performance of a broad-based market index is included for comparison. The blended index shows how the fund's performance compares with the returns of a combination of two widely used indexes related to the fund's investments.

After-tax returns They reflect the highest individual federal marginal income tax rates 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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R6 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown below are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R6 shares. Returns for Class R6 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Calendar year total returns — Class R6 (%)

Year-to-date total return The fund's total return for the nine months ended March 31, 2013 was -3.21%.

Best quarter:  Q3 '10,  3.51%

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 in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes 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:

Sold

Expense Example (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class C (International Small Company Fund - Class C)	1,724	4,296	6,352	9,647

Kept

Expense Example, No Redemption (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class C (International Small Company Fund - Class C)	1,624	4,296	6,352	9,647

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual-listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations.

The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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 performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/FundPerformance, or by calling Signature Services at 1-800-225-5291, Monday–Thursday between 8:00 A.M. and 7:00 P.M. and on Fridays between 8:00 A.M. and 6:00 P.M., Eastern Time.

Calendar year total returns These do not include sales charges and would have been lower if they did.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns They reflect the highest individual federal marginal income-tax rates 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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class C shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class C shares. Returns for Class C shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Growth Opportunities Fund) (International Growth Opportunities Fund - Class R3 and Class R5) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R3	1,577	4,198	6,238	9,575
Class R5	1,526	4,086	6,106	9,485

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

Continental Europe European securities may be affected significantly by economic, regulatory or political developments affecting European issuers. All countries in Europe may be significantly affected by fiscal and monetary controls implemented by the European Economic and Monetary Union. Eastern European markets are relatively undeveloped and may be particularly sensitive to economic and political events affecting those countries.

Japan A fund that holds Japanese securities may be affected significantly by economic, regulatory or political developments affecting Japanese issuers. The Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect Japanese markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the Japanese securities markets, as well as cross-shareholdings in Japanese companies, may affect trading prices and volumes in these markets.

United Kingdom A fund that holds U.K. securities may be affected significantly by economic, regulatory or political developments affecting U.K. issuers. Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences. Furthermore, the U.K. is closely tied to Continental Europe and may be impacted to a greater extent than other countries by euro common currency economic and political events.

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. 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.

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.

Medium company risk The prices of medium 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.

Small company risk Stocks of smaller companies are more volatile than stocks of larger companies. 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

This section normally shows how the fund's total returns have varied from year to year, along with a broad-based market index for reference. Because the fund had less than a full calendar year of operations as of the date of this prospectus, there is no past performance to report.

Investment objective

To seek long-term capital appreciation.

Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder fees (%) (fees paid directly from your investment)

Shareholder Fees (International Small Company Fund)	Class R6 (International Small Company Fund - Class R6)
Maximum front-end sales charge (load) on purchases as a % of purchase price	none
Maximum deferred sales charge (load) as a % of purchase or sale price, whichever is less	none

Annual Fund Operating Expenses (International Small Company Fund)		Class R6 (International Small Company Fund - Class R6)
Management fee		0.95%
Other expenses	[1]	15.20%
Total annual fund operating expenses		16.15%

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R6 (International Small Company Fund - Class R6)	1,525	4,084	6,104	9,483

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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 performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/InstitutionalPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns They reflect the highest individual federal marginal income-tax rates 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.

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

Please see below a hypothetical example showing the expenses of a $10,000 investment at the end for the time periods indicated assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Small Company Fund) (International Small Company Fund - Class R1, Class R2 and Class R4) (USD $)	1 Year	3 Years	5 Years	10 Years

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 relected 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 9% of the average value of its portfolio.

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Global Absolute Return Strategies Fund) (Global Absolute Return Strategies Fund - Class R1 and Class R4) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R1	1,618	4,285	6,339	9,640
Class R4	1,584	4,212	6,255	9,586

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 the period from December 19, 2011 (commencement of operations) through July 31, 2012, the fund's portfolio turnover rate was 33% of the average value of its portfolio.

Principal investment strategies

The fund has a broad investment mandate that permits it to use an extensive range of investment strategies and to invest in a wide spectrum of equity and fixed-income securities, as well as derivative instruments, in pursuing its investment objective.

The fund invests in equity securities of U.S. and foreign companies of various market capitalizations. The fund also invests in fixed-income securities, which are not subject to any credit rating or maturity limitations, issued by companies and government and supranational entities around the world, including high-yield non-investment-grade securities (i.e., junk bonds). The fund may invest in emerging as well as developed markets and may invest a significant portion of its assets in the securities of companies in particular economic sectors.

The fund also may invest extensively in derivative instruments, which are generally financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate, or index, and may relate to equity securities, fixed-income securities, interest rates, total return rates, currencies or currency exchange rates, and related indexes. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in or exposed to obligations of issuers or obligors located outside of the United States.

The subadvisor employs a "global multi-asset strategy" and seeks to achieve total return by delivering a diversified global portfolio that makes use of multiple strategies across various asset classes. It aims to exploit market cyclicality and a diverse array of inefficiencies across and within global markets to maximize risk adjusted absolute return by investing in listed equity, equity-related and debt securities, and derivatives or other instruments, both for investment and hedging purposes. The fund invests in derivative instruments (which will be used routinely), including futures, options, swaps (including credit default swaps and variance swaps), and foreign currency forward contracts.

The subadvisor manages the fund's investment strategies dynamically over time, and will actively modify investment strategies and develop new strategies in response to additional research, changing market conditions, or other factors. The fund's strategies seek to deliver returns commensurate with reasonable levels of risk and tangible diversification benefits, while having both sufficient liquidity and capacity to benefit the fund in a significant way. The fund also may hold cash or invest its cash balances in cash equivalents and short-term investments, including money market funds, in order to cover the derivative transactions or otherwise in its discretion.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. In addition, although the subadvisor aims to maximize absolute return, there is no guarantee that the fund will generate positive returns. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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 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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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. 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.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Calendar year total returns Calendar year total returns are shown only for Class R1 shares and would be different for other share classes.

Average annual total returns Performance of a broad-based market index is included for comparison. The MSCI World Index shows how the fund's performance compares with the returns of similar investments.

After-tax returns These are shown only for Class R1 shares and would be different for other classes. They reflect the highest individual federal marginal income tax rates 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.

Because Class R1 and Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R1 and Class R4 shares, as applicable. Returns for Class R1 and Class R4 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 48% of the average value of its portfolio.

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/FundPerformance, or by calling Signature Services at 1-800-225-5291, Monday–Thursday between 8:00 A.M. and 7:00 P.M. and on Fridays between 8:00 A.M. and 6:00 P.M., Eastern Time.

Average annual total returns Performance of a broad-based market index is included for comparison. The blended index shows how the fund's performance compares with the returns of a combination of two widely used indexes related to the fund's investments.

After-tax returns They reflect the highest individual federal marginal income tax rates 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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class C shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class C shares. Returns for Class C shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Global High Yield Fund) (Global High Yield Fund - Class R1, Class R2 and Class R4) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R1	1,573	4,188	6,227	9,568

Class R4	1,539	4,114	6,139	9,508

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 48% of the average value of its portfolio.

These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, most business days.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R3 and Class R5 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R3 and Class R5 shares, as applicable. Returns for Class R3 and Class R5 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Investment objective

To seek maximum total return, which consists of income on its investments and capital appreciation.

Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder fees (%) (fees paid directly from your investment)

Shareholder Fees (Global High Yield Fund)	Class R6 (Global High Yield Fund - Class R6)
Maximum front-end sales charge (load) on purchases as a % of purchase price	none
Maximum deferred sales charge (load) as a % of purchase or sale price, whichever is less	none

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Global High Yield Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R6 (Global High Yield Fund - Class R6)	1,509	4,048	6,061	9,453

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 48% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe.

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 60% of the average value of its portfolio.

Principal investment strategies

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/FundPerformance, or by calling Signature Services at 1-800-225-5291, Monday–Thursday between 8:00 A.M. and 7:00 P.M. and on Fridays between 8:00 A.M. and 6:00 P.M., Eastern Time.

Calendar year total returns These do not include sales charges and would have been lower if they did.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns They reflect the highest individual federal marginal income tax rates 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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to this date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class C shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class C shares. Returns for Class C shares would have been substantially similar to returns of Class A because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Short Duration Credit Opportunities Fund) (Short Duration Credit Opportunities Fund - Class R1, Class R2 and Class R4) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R1	1,560	4,161	6,194	9,546
Class R2	1,539	4,114	6,139	9,508
Class R4	1,526	4,086	6,106	9,485

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 60% of the average value of its portfolio.

Principal investment strategies

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/Retirement Performance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Calendar year total returns Calendar year total returns are shown only for Class R3 shares and would be different for other share classes.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns These are shown only for Class R3 shares and would be different for other classes. They reflect the highest individual federal marginal income tax rates 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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R3 and Class R5 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R3 and Class R5 shares, as applicable. Returns for Class R3 and Class R5 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Calendar year total returns — Class R3 (%)

Year-to-date total return The fund's total return for the three months ended March 31, 2013 was -3.15%.

Investment objective

To seek to maximize total return, which consists of income on its investments and capital appreciation.

Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder fees (%) (fees paid directly from your investment)

Shareholder Fees (Short Duration Credit Opportunities Fund)	Class R6 (Short Duration Credit Opportunities Fund - Class R6)
Maximum front-end sales charge (load) on purchases as a % of purchase price	none
Maximum deferred sales charge (load) as a % of purchase or sale price, whichever is less	none

Annual fund operating expenses (%) (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses (Short Duration Credit Opportunities Fund)		Class R6 (Short Duration Credit Opportunities Fund - Class R6)
Management fee		0.70%
Other expenses	[1]	15.11%
Total annual fund operating expenses		15.81%

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 assuming that you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Short Duration Credit Opportunities Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R6 (Short Duration Credit Opportunities Fund - Class R6)	1,496	4,019	6,027	9,428

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 60% of the average value of its portfolio.

Principal investment strategies

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/ return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns They reflect the highest individual federal marginal income tax rates 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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R6 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown below are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R6 shares. Returns for Class R6 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (Alternative Asset Allocation Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R4 (Alternative Asset Allocation Fund - Class R4)	164	584	1,030	2,270

Portfolio turnover

The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and 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 performance of the underlying funds and the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 34% of the average value of its portfolio.

Principal investment strategies

The fund will seek to achieve its objective by investing in "alternative asset classes." The fund invests in other funds as well as other types of investments as described below.

The fund will allocate its assets among other funds in the John Hancock Funds complex and other investment companies, including exchange-traded funds (ETFs) (collectively, "Underlying Funds"), that emphasize alternative or non-traditional asset categories or investment strategies such as international small-cap stocks, emerging-market equity, commodities, market neutral (long/short), global real estate, natural resources, TIPS (Treasury Inflation-Protected Securities), global bonds, high yield, bank loans, foreign currency trading strategies, absolute return strategies, managed futures, arbitrage strategies, tactical investment strategies and emerging-market debt. In addition, the fund may also directly invest in exchange-traded notes (ETNs).

The fund may use a portion of its assets to employ a market neutral (long/short) strategy by simultaneously purchasing a security and entering into a short sale on the security.

The fund operates as a fund of funds and may invest in Underlying Funds and in other types of investments as described below. The fund may purchase any Underlying Funds except other funds of funds. When purchasing shares of other John Hancock Funds, the fund only purchases NAV shares (which are not subject to Rule 12b-1 fees).

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 8 of the prospectus.

Risks of investing in the fund of funds

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

Asset allocation risk Although asset allocation among different asset categories generally limits risk and exposure to any one category, the risk remains that the advisor may favor an asset category that performs poorly relative to the other asset categories. To the extent that alternative asset categories underperform the general stock market, the fund would perform poorly relative to a fund invested primarily in the general stock market.

Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.

Exchange-traded notes risk Similar to ETFs, owning an ETN generally reflects the risks of owning the assets that comprise the underlying market benchmark or strategy that the ETN is designed to reflect. ETNs also are subject to issuer and fixed-income risk.

Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.

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.

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.

Risks of investing in the underlying funds

Commodity risk The market price of commodity investments may be volatile due to fluctuating demand, supply disruption, speculation and other factors.

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

Emerging-market 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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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.

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

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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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.

Natural resources risk The natural resources industry can be significantly affected by events relating to international political and economic developments, energy conservation, the success of exploration projects, commodity prices, and taxes and other governmental regulations.

Non-diversified risk Overall risk can be reduced by investing in securities from a diversified pool of issuers and is increased by investing in securities of a small number of issuers. Investments in a non-diversified fund may magnify the fund's losses from adverse events affecting a particular issuer.

Real estate securities risk Investing in securities of companies in the real estate industry subjects a fund to the risks associated with the direct ownership of real estate.

Past performance

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Average annual total returns Performance of broad-based market indexes is included for comparison.

After-tax returns They reflect the highest individual federal marginal income-tax rates 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.

Performance information prior to December 20, 2010 reflects an allocation to a different mix of underlying funds and would have been different if the fund's investments had been allocated to its current mix of underlying funds.

January 2, 2009 is the inception date for the oldest class of shares, Class A shares. Because Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R4 shares. Returns for Class R4 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Calendar year total returns — Class R4 (%)

Year-to-date total return The fund's total return for the 3 months ended March 31, 2013 was 0.96%.

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 in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes 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:

Sold

Expense Example (International Growth Opportunities Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class C (International Growth Opportunities Fund - Class C)	1,723	4,294	6,350	9,646

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

Continental Europe European securities may be affected significantly by economic, regulatory or political developments affecting European issuers. All countries in Europe may be significantly affected by fiscal and monetary controls implemented by the European Economic and Monetary Union. Eastern European markets are relatively undeveloped and may be particularly sensitive to economic and political events affecting those countries.

Japan A fund that holds Japanese securities may be affected significantly by economic, regulatory or political developments affecting Japanese issuers. The Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect Japanese markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the Japanese securities markets, as well as cross-shareholdings in Japanese companies, may affect trading prices and volumes in these markets.

United Kingdom A fund that holds U.K. securities may be affected significantly by economic, regulatory or political developments affecting U.K. issuers. Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences. Furthermore, the U.K. is closely tied to Continental Europe and may be impacted to a greater extent than other countries by euro common currency economic and political events.

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. 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.

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.

Medium company risk The prices of medium 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.

Small company risk Stocks of smaller companies are more volatile than stocks of larger companies. 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

This section normally shows how the fund's total returns have varied from year to year, along with a broad-based market index for reference. Because the fund had less than a full calendar year of operations as of the date of this prospectus, there is no past performance to report.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

Continental Europe European securities may be affected significantly by economic, regulatory or political developments affecting European issuers. All countries in Europe may be significantly affected by fiscal and monetary controls implemented by the European Economic and Monetary Union. Eastern European markets are relatively undeveloped and may be particularly sensitive to economic and political events affecting those countries.

Japan A fund that holds Japanese securities may be affected significantly by economic, regulatory or political developments affecting Japanese issuers. The Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect Japanese markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the Japanese securities markets, as well as cross-shareholdings in Japanese companies, may affect trading prices and volumes in these markets.

United Kingdom A fund that holds U.K. securities may be affected significantly by economic, regulatory or political developments affecting U.K. issuers. Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences. Furthermore, the U.K. is closely tied to Continental Europe and may be impacted to a greater extent than other countries by euro common currency economic and political events.

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. 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.

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.

Medium company risk The prices of medium 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.

Small company risk Stocks of smaller companies are more volatile than stocks of larger companies. 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.

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Growth Opportunities Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R6 (International Growth Opportunities Fund - Class R6)	1,522	4,076	6,095	9,477

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Principal investment strategies

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

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 in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes 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:

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market Capitalization Weighted Approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity.

The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class A shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class A shares. Returns for Class A shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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.

The fund does not seek current income as an investment objective and investments will not be based upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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 performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/InstitutionalPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns They reflect the highest individual federal marginal income-tax rates 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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class I shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class I shares. Returns for Class I shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes 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:

Sold

Expense Example (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class C (International Small Company Fund - Class C)	1,724	4,296	6,352	9,647

Kept

Expense Example, No Redemption (International Small Company Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class C (International Small Company Fund - Class C)	1,624	4,296	6,352	9,647

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual-listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations.

The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

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.

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.

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.

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 performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Calendar year total returns Calendar year total returns are shown only for Class R1 shares and would be different for other share classes.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns These are shown only for Class R1 shares and would be different for other classes. They relect the highest individual federal marginal income-tax rates in effect as of the date provided and do not relect 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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class R1, Class R2 and Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class R1, Class R2 and Class R4 shares, as applicable. Returns for Class R1, Class R2 and Class R4 shares would have been substantially similar to returns of Class NAV shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Small Company Fund) (International Small Company Fund - Class R3 and Class R5) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R3	1,581	4,205	6,246	9,580
Class R5	1,529	4,093	6,115	9,491

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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.

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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:

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 9% 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.

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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. 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 intends to invest and the main risks associated with each of them:

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.

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.

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.

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

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 the period from December 19, 2011 (commencement of operations) through July 31, 2012, the fund's portfolio turnover rate was 33% of the average value of its portfolio.

Strategy [Heading]

Principal investment strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund has a broad investment mandate that permits it to use an extensive range of investment strategies and to invest in a wide spectrum of equity and fixed-income securities, as well as derivative instruments, in pursuing its investment objective.

The fund invests in equity securities of U.S. and foreign companies of various market capitalizations. The fund also invests in fixed-income securities, which are not subject to any credit rating or maturity limitations, issued by companies and government and supranational entities around the world, including high-yield non-investment-grade securities (i.e., junk bonds). The fund may invest in emerging as well as developed markets and may invest a significant portion of its assets in the securities of companies in particular economic sectors.

The fund also may invest extensively in derivative instruments, which are generally financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate, or index, and may relate to equity securities, fixed-income securities, interest rates, total return rates, currencies or currency exchange rates, and related indexes. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in or exposed to obligations of issuers or obligors located outside of the United States.

The subadvisor employs a "global multi-asset strategy" and seeks to achieve total return by delivering a diversified global portfolio that makes use of multiple strategies across various asset classes. It aims to exploit market cyclicality and a diverse array of inefficiencies across and within global markets to maximize risk adjusted absolute return by investing in listed equity, equity-related and debt securities, and derivatives or other instruments, both for investment and hedging purposes. The fund invests in derivative instruments (which will be used routinely), including futures, options, swaps (including credit default swaps and variance swaps), and foreign currency forward contracts.

The subadvisor manages the fund's investment strategies dynamically over time, and will actively modify investment strategies and develop new strategies in response to additional research, changing market conditions, or other factors. The fund's strategies seek to deliver returns commensurate with reasonable levels of risk and tangible diversification benefits, while having both sufficient liquidity and capacity to benefit the fund in a significant way. The fund also may hold cash or invest its cash balances in cash equivalents and short-term investments, including money market funds, in order to cover the derivative transactions or otherwise in its discretion.

Risk [Heading]

rr_RiskHeading

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. In addition, although the subadvisor aims to maximize absolute return, there is no guarantee that the fund will generate positive returns. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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 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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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. 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.

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.

The following performance information in the bar chart and table below 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. However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Calendar year total returns Calendar year total returns are shown only for Class R1 shares and would be different for other share classes.

Average annual total returns Performance of a broad-based market index is included for comparison. The MSCI World Index shows how the fund's performance compares with the returns of similar investments.

After-tax returns These are shown only for Class R1 shares and would be different for other classes. They reflect the highest individual federal marginal income tax rates 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.

Bank of America Merrill Lynch US Dollar 1-Month LIBID Average Index tracks the performance of a synthetic asset paying LIBID (London Interbank Bid Rate) to a stated maturity.

MSCI World Index is a free float-adjusted market capitalization weighted index that is designed to measure equity market performance of developed markets.

Because Class R1 and Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R1 and Class R4 shares, as applicable. Returns for Class R1 and Class R4 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in or exposed to obligations of issuers or obligors located outside of the United States.

The subadvisor employs a "global multi-asset strategy" and seeks to achieve total return by delivering a diversified global portfolio that makes use of multiple strategies across various asset classes. It aims to exploit market cyclicality and a diverse array of inefficiencies across and within global markets to maximize risk adjusted absolute return by investing in listed equity, equity-related and debt securities, and derivatives or other instruments, both for investment and hedging purposes. The fund invests in derivative instruments (which will be used routinely), including futures, options, swaps (including credit default swaps and variance swaps), and foreign currency forward contracts.

The subadvisor manages the fund's investment strategies dynamically over time, and will actively modify investment strategies and develop new strategies in response to additional research, changing market conditions, or other factors. The fund's strategies seek to deliver returns commensurate with reasonable levels of risk and tangible diversification benefits, while having both sufficient liquidity and capacity to benefit the fund in a significant way. The fund also may hold cash or invest its cash balances in cash equivalents and short-term investments, including money market funds, in order to cover the derivative transactions or otherwise in its discretion.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. In addition, although the subadvisor aims to maximize absolute return, there is no guarantee that the fund will generate positive returns. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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 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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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. 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.

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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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.

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.

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class C shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class C shares. Returns for Class C shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 48% of the average value of its portfolio.

Strategy [Heading]

Principal investment strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds.

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

Risk [Heading]

rr_RiskHeading

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield bonds issued by U.S. and foreign corporations and foreign governments and their agencies and instrumentalities. Under normal circumstances, the fund will invest at least 40% of its net assets in foreign securities. The high-yield bonds in which the fund invests will consist of both high-yield and emerging-markets fixed-income securities, as defined below.

High-yield securities include fixed-income securities and other instruments (including derivatives) rated below investment grade (or, if unrated, of equivalent quality as determined by the subadvisor). These types of securities and instruments are commonly referred to as "high-yield securities" or "junk bonds" and may include, among other things, bonds, debentures, notes, equipment trust certificates, commercial paper, floating rate loans, loan participations, preferred stock, mortgage- and asset-backed securities, and other obligations of U.S. and foreign issuers. High-yield securities also include securities or other instruments whose return is based on return of high-yield securities, including derivative instruments and instruments created to hedge or gain exposure to the high-yield markets, such as Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes.

Emerging-markets fixed-income securities include fixed-income securities and other instruments (including derivatives) that are tied economically to countries with emerging securities markets or whose performance is linked to those markets, economies or ability to repay loans. A security or instrument is tied economically to an emerging-market country if it is principally traded on the country's securities markets or the issuer is organized or principally operates in the country, derives a majority of its income from its operations within the country or has a majority of its assets within the country. Emerging-markets fixed-income securities also include securities or other instruments whose return is based on the return of emerging securities markets or securities tied economically to those markets, including the derivative instruments described above and instruments created to hedge or gain exposure to these markets. With respect to emerging markets, it is anticipated that the fund will focus most of its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The fund also may invest in a number of countries deemed by the subadvisor to be developed markets.

Securities in which the fund invests may be denominated in foreign currencies or the U.S. dollar.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The subadvisor normally maintains an average portfolio duration of between two and seven years. However, the fund's average duration may be outside this range, and the fund may invest in securities of any duration and maturity.

The fund's investment process may result in an extremely high portfolio turnover ratio and increased trading expenses.

The fund's investments may include, among other things, sovereign debt securities, corporate debt securities, structured notes, securities issued by supranational organizations, fixed- and floating-rate commercial loans, securitized loan participations, Rule 144A securities, asset-backed securities, depositary receipts, mortgage-related securities (including transferable private issuer mortgage-backed securities), nonpublicly traded securities, payment-in-kind bonds, inflation-protected and other index-linked securities, interest-only securities, step-up securities, zero coupon bonds and derivatives related to these types of securities such as U.S. Treasury futures, currency futures, index futures, interest rate swaps, credit default swaps and credit default swaps on securities and credit indexes. The fund may invest in fixed- and floating-rate loans, which investments generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid. The fund seeks capital appreciation through industry selection, sector selection and security selection.

Risk [Heading]

rr_RiskHeading

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R3 and Class R5 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R3 and Class R5 shares, as applicable. Returns for Class R3 and Class R5 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R6 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown below are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R6 shares. Returns for Class R6 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

Emerging markets risk The risks of investing in foreign securities are greater for investments in emerging markets.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Strategy [Heading]

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

Risk [Heading]

rr_RiskHeading

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

However, past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance for the fund is updated daily, monthly and quarterly and may be obtained at our Web site: www.jhfunds.com/RetirementPerformance, or by calling 1-888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern Time, on most business days.

Calendar year total returns Calendar year total returns are shown only for Class R1 shares and would be different for other share classes.

Average annual total returns Performance of a broad-based market index is included for comparison.

After-tax returns These are shown only for Class R1 shares and would be different for other classes. They reflect the highest individual federal marginal income tax rates 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.

Prior to March 28, 2013, the fund was not open to investment by the general public. Performance prior to that date does not reflect additional expenses associated with publicly offering the fund's shares. Because Class R1, Class R2 and Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R1, Class R2 and Class R4 shares, as applicable. Returns for Class R1, Class R2 and Class R4 shares would have been substantially similar to returns of Class A shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund will normally invest in a portfolio of fixed-income securities. Under normal circumstances, the fund will invest at least 80% of its assets in bonds and related investments and maintain an average portfolio duration of approximately three years or less. Related investments include derivatives (such as total return swaps, interest-rate swaps, credit default swaps, credit default swap indexes and futures), bank loans and credit-linked notes. Related investments may be used for hedging purposes or as a substitute for investing in bonds. The fund's subadvisor has broad discretion to allocate the fund's assets among the following segments of the global market for fixed-income securities:

• U.S. government obligations

• Mortgage- and asset-backed securities

• Investment and non-investment-grade U.S. and foreign corporate debt, including floating-rate loans and

• Investment and non-investment-grade sovereign debt, including issuers in emerging markets.

The subadvisor uses a combination of quantitative models that seek to measure the relative risks and opportunities of each market segment based upon economic, market, political, currency and technical data, and its own assessment of economic and market conditions, to create an optimal risk/ return allocation of the fund's assets among various segments of the fixed-income market. After the subadvisor makes its sector allocations, it uses traditional credit analysis to identify individual securities for the fund's portfolio.

In selecting U.S. government and agency obligations and mortgage-backed securities for investment, the subadvisor may consider, among other factors, yield curve shifts, credit quality, and changing prepayment patterns.

In selecting corporate debt for investment, the subadvisor may consider, among other factors, the strength of the issuer's financial resources and sensitivity to economic conditions and trends, the issuer's operating history and the experience and track record of the issuer's management.

In selecting foreign government debt for investment, the subadvisor may consider, among other factors, currency, inflation and interest rate trends, growth rate forecasts, liquidity of a country's debt markets, fiscal policies, political outlook and tax environment.

The fund may invest in fixed- and floating-rate loans, which generally will be in the form of loan participations and assignments of portions of such loans. While some loans are collateralized and senior to an issuer's other debt securities, other loans may be unsecured and/or subordinated to other securities. If the fund purchases a loan participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower. Some bank loans may be illiquid.

For hedging purposes or as a substitute for investing in bonds, the fund may engage in derivative transactions that include U.S. Treasury futures, currency futures, index futures, interest-rate swaps, credit swaps and credit default swaps on securities and credit indexes to a significant extent. The fund seeks capital appreciation through industry selection, sector selection and security selection.

The fund may invest in securities of any credit rating (including unrated securities) and may invest without limit in higher risk, below-investment-grade debt securities, commonly referred to as "high-yield securities" or "junk bonds."

The fund normally maintains an average portfolio duration of approximately three years or less. However, the fund may invest in securities of any duration and maturity.

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors 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.

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

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. 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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default swaps.

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.

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

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.

Loan participations risk Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk and the risks of being a lender.

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.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.

Portfolio Turnover [Text Block]

The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and 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 performance of the underlying funds and the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 34% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund will seek to achieve its objective by investing in "alternative asset classes." The fund invests in other funds as well as other types of investments as described below.

The fund will allocate its assets among other funds in the John Hancock Funds complex and other investment companies, including exchange-traded funds (ETFs) (collectively, "Underlying Funds"), that emphasize alternative or non-traditional asset categories or investment strategies such as international small-cap stocks, emerging-market equity, commodities, market neutral (long/short), global real estate, natural resources, TIPS (Treasury Inflation-Protected Securities), global bonds, high yield, bank loans, foreign currency trading strategies, absolute return strategies, managed futures, arbitrage strategies, tactical investment strategies and emerging-market debt. In addition, the fund may also directly invest in exchange-traded notes (ETNs).

The fund may use a portion of its assets to employ a market neutral (long/short) strategy by simultaneously purchasing a security and entering into a short sale on the security.

The fund operates as a fund of funds and may invest in Underlying Funds and in other types of investments as described below. The fund may purchase any Underlying Funds except other funds of funds. When purchasing shares of other John Hancock Funds, the fund only purchases NAV shares (which are not subject to Rule 12b-1 fees).

Risk [Heading]

rr_RiskHeading

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 8 of the prospectus.

Risks of investing in the fund of funds

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

Asset allocation risk Although asset allocation among different asset categories generally limits risk and exposure to any one category, the risk remains that the advisor may favor an asset category that performs poorly relative to the other asset categories. To the extent that alternative asset categories underperform the general stock market, the fund would perform poorly relative to a fund invested primarily in the general stock market.

Exchange-traded funds risk Owning an ETF generally reflects the risks of owning the underlying securities it is designed to track.

Exchange-traded notes risk Similar to ETFs, owning an ETN generally reflects the risks of owning the assets that comprise the underlying market benchmark or strategy that the ETN is designed to reflect. ETNs also are subject to issuer and fixed-income risk.

Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.

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.

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.

Risks of investing in the underlying funds

Commodity risk The market price of commodity investments may be volatile due to fluctuating demand, supply disruption, speculation and other factors.

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.

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Economic and market events risk Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide.

Emerging-market 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.

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. 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 intends to invest and the main risks associated with each of them:

Credit default 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 credit default 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.

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

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.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance) and taxable distributions.

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.

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.

Natural resources risk The natural resources industry can be significantly affected by events relating to international political and economic developments, energy conservation, the success of exploration projects, commodity prices, and taxes and other governmental regulations.

Non-diversified risk Overall risk can be reduced by investing in securities from a diversified pool of issuers and is increased by investing in securities of a small number of issuers. Investments in a non-diversified fund may magnify the fund's losses from adverse events affecting a particular issuer.

Real estate securities risk Investing in securities of companies in the real estate industry subjects a fund to the risks associated with the direct ownership of real estate.

Performance information prior to December 20, 2010 reflects an allocation to a different mix of underlying funds and would have been different if the fund's investments had been allocated to its current mix of underlying funds.

January 2, 2009 is the inception date for the oldest class of shares, Class A shares. Because Class R4 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class A shares that have been recalculated to apply the gross fees and expenses of Class R4 shares. Returns for Class R4 shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Strategy Narrative [Text Block]

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

Continental Europe European securities may be affected significantly by economic, regulatory or political developments affecting European issuers. All countries in Europe may be significantly affected by fiscal and monetary controls implemented by the European Economic and Monetary Union. Eastern European markets are relatively undeveloped and may be particularly sensitive to economic and political events affecting those countries.

Japan A fund that holds Japanese securities may be affected significantly by economic, regulatory or political developments affecting Japanese issuers. The Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect Japanese markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the Japanese securities markets, as well as cross-shareholdings in Japanese companies, may affect trading prices and volumes in these markets.

United Kingdom A fund that holds U.K. securities may be affected significantly by economic, regulatory or political developments affecting U.K. issuers. Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences. Furthermore, the U.K. is closely tied to Continental Europe and may be impacted to a greater extent than other countries by euro common currency economic and political events.

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. 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.

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.

Medium company risk The prices of medium 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.

Small company risk Stocks of smaller companies are more volatile than stocks of larger companies. 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.

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences.

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 the fiscal period from July 19, 2012 to August 31, 2012, the fund's portfolio turnover rate was 1% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund normally invests at least 80% of the value of its net assets (plus borrowings for investment purposes) in common stocks issued by companies domiciled outside the United States. The fund does not usually focus its investments in a particular industry or country. A significant part of the fund's assets will normally be divided among Asia (including Australia and New Zealand), continental Europe, Japan and the United Kingdom. The fund may invest up to 30% (measured at the time of purchase) of its total assets in countries in emerging markets when the fund's investment team believes it would be appropriate to do so. The fund may invest in companies of any market capitalization.

The fund's investment team uses rigorous fundamental research and a bottom-up approach to country and asset allocation, with the objective of making long-term investments in companies it believes can sustain above-average growth rates and that currently trade at prices that do not fully reflect those rates of growth. The investment team looks for companies that it believes have strong competitive positions within attractive industries, strong balance sheets and a positive approach toward shareholders. Research is conducted with a five-year time horizon and the portfolio is expected to have a correspondingly low rate of turnover. To determine how to allocate the fund's assets geographically, the fund's investment team evaluates economic, market and political trends worldwide. Among the factors considered are the growth potential of economies and securities markets, technological developments, currency exchange rates and political and social conditions.

The fund also may invest in foreign issuers through American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs) or similar investment vehicles.

Risk [Heading]

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

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

Currency risk Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active position, will decline in value relative to the U.S. dollar.

Emerging-market 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.

Asia Specific risks include political and economic factors affecting issuers in Pacific Basin countries and restrictions in some Asian countries regarding the extent to which foreigners may invest in their securities markets. Securities of issuers located in some Asian countries tend to have volatile prices and may offer significant potential for loss as well as gain. Certain companies in Asia may not have firmly established product markets, may lack depth of management or may be more vulnerable to political or economic developments such as nationalization of their own industries.

Eastern Europe Specific risks vary greatly between markets but include corporate governance, fiscal stability, banking regulations, European Union accession, global commodity prices, political stability and market liquidity.

Latin America Specific risks include high inflation rates and high interest rates. The emergence of the Latin American economies and securities markets will require continued economic and fiscal discipline which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the United States, and by world prices for oil and other commodities.

South Africa Specific risks include the transfer of assets to black economic empowerment groups, tax increases, corporate governance, banking regulations, commodity prices, political changes and asset appropriation.

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.

Asia (including Australia and New Zealand) The developed Asian economies are heavily dependent on international trade and can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade, principally, the U.S., Japan, China and the European Union. The countries in this region are also heavily dependent on exports and are thus particularly vulnerable to any weakening in global demand for these products. The Australian and New Zealand economies are dependent on the economies of Asian countries and on the price and demand for agricultural products and natural resources. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the fund.

Continental Europe European securities may be affected significantly by economic, regulatory or political developments affecting European issuers. All countries in Europe may be significantly affected by fiscal and monetary controls implemented by the European Economic and Monetary Union. Eastern European markets are relatively undeveloped and may be particularly sensitive to economic and political events affecting those countries.

Japan A fund that holds Japanese securities may be affected significantly by economic, regulatory or political developments affecting Japanese issuers. The Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect Japanese markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the Japanese securities markets, as well as cross-shareholdings in Japanese companies, may affect trading prices and volumes in these markets.

United Kingdom A fund that holds U.K. securities may be affected significantly by economic, regulatory or political developments affecting U.K. issuers. Responses to the high level of public and private debt by the U.K. government, central bank and others may not work, and may limit future growth and economic recovery or have other unintended consequences. Furthermore, the U.K. is closely tied to Continental Europe and may be impacted to a greater extent than other countries by euro common currency economic and political events.

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. 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.

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.

Medium company risk The prices of medium 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.

Small company risk Stocks of smaller companies are more volatile than stocks of larger companies. 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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market Capitalization Weighted Approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class A shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class A shares. Returns for Class A shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Strategy Narrative [Text Block]

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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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.

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.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class I shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class I shares. Returns for Class I shares would have been substantially similar to returns of Class NAV shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual-listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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.

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 relected 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 9% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free loat, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization may take into consideration the free loat 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors inluence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 8 of the prospectus.

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 luctuations and adverse political and economic developments. Investments in emerging-market countries are subject to greater levels of foreign investment risk.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

Risk [Heading]

Principal risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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.

Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

rr_RiskNarrativeTextBlock

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 7 of the prospectus.

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

Emerging-market 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.

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 intends to invest and the main risks associated with each of them:

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.

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.

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.

After-tax returns They reflect the highest individual federal marginal income-tax rates 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.

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

Investment objective

To seek long-term capital appreciation.

Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder fees (%) (fees paid directly from your investment)

Shareholder Fees (International Small Company Fund - Class R3 and Class R5) (International Small Company Fund)	Class R3	Class R5
Maximum front-end sales charge (load) on purchases as a % of purchase price	none	none
Maximum deferred sales charge (load) as a % of purchase or sale price, whichever is less	none	none

Annual fund operating expenses (%) (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses (International Small Company Fund - Class R3 and Class R5) (International Small Company Fund)		Class R3	Class R5
Management fee		0.95%	0.95%
Distribution and service (12b-1) fees		0.50%	none

Total annual fund operating expenses		16.80%	16.20%

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 assuming you redeem all of your shares at the end of those periods. The example assumes a 5% average annual return. The example assumes 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 (International Small Company Fund) (International Small Company Fund - Class R3 and Class R5) (USD $)	1 Year	3 Years	5 Years	10 Years
Class R3	1,581	4,205	6,246	9,580
Class R5	1,529	4,093	6,115	9,491

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 9% 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 May 31, 2013, the maximum market capitalization range of eligible companies for purchase was approximately $1,637 million to $5,019 million, 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 securities listed or traded in the form of International Depositary Receipts (IDRs), American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), Non-Voting Depositary Receipts (NVDRs) and other similar securities, including dual- listed securities. Each of these securities may be traded within or outside the issuer's domicile country.

The subadvisor 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 subadvisor first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. The subadvisor 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. This threshold will vary by country or region, and dollar amounts will change due to market conditions.

The fund intends to purchase securities in each applicable country using a market capitalization weighted approach. The subadvisor, using this approach and its judgment, will seek to set country weights based on the relative market capitalizations of eligible small companies within each country. See "Market capitalization weighted approach" below. The weightings of countries in the fund may vary from their weightings in international indices, such as those published by FTSE International, MSCI or Citigroup.

The fund also may use derivatives such as futures contracts and options on futures contracts, to gain market exposure on the fund's uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. The fund may enter into futures contracts and options on futures contracts for foreign or U.S. equity securities and indices. The fund may also enter into forward currency contracts to facilitate the settlement of equity purchases of foreign securities, repatriation of foreign currency balances or exchange of one foreign currency for another currency. In addition to money market instruments and other short-term investments, the fund may invest in affiliated and unaffiliated unregistered money market funds to manage the fund's cash pending investment in other securities or to maintain liquidity for the payment of redemptions or 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 upon an issuer's dividend payment policy or record. However, many of the companies whose securities will be included in the fund do pay dividends. It is anticipated, therefore, that the fund will receive dividend income.

The subadvisor will determine in its discretion when and whether to invest in countries that have been authorized for investment by its Investment Committee, depending on a number of factors such as asset growth in the fund and characteristics of each country's market. The subadvisor's Investment Committee may authorize other countries for investment in the future and the fund may continue to hold investments in countries not currently authorized for investment but that had previously been authorized for investment.

Market capitalization weighted approach

The fund structure involves market capitalization weighting in determining 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 subadvisor for a variety of factors. The subadvisor may consider such factors as free float, momentum, trading strategies, liquidity management and other factors determined to be appropriate by the subadvisor given market conditions. The subadvisor 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 the assets of the fund. The subadvisor may exclude the stock of a company that meets applicable market capitalization criteria if the subadvisor determines, in its judgment, that the purchase of such security is inappropriate in light of other conditions. 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. The calculation of country market capitalization 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. As a result, the weighting of certain countries will likely vary from their weighting in published international indices. Also, deviation from target weights may result from holding securities from countries that are no longer authorized for future investments.

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. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity.

After-tax returns are not relevant to shares held in an IRA, 401(k) or other tax-advantaged investment plan.

April 28, 2006 is the inception date for the oldest class of shares, Class NAV shares. Because Class R3 and Class R5 shares of the fund had not commenced operations prior to the date of this prospectus, the returns shown are those of Class NAV shares that have been recalculated to apply the gross fees and expenses of Class R3 and Class R5 shares, as applicable.Returns for Class R3 and Class R5 shares would have been substantially similar to returns of Class NAV shares because the share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.
