[1]	"Service plan fee" has been restated to reflect maximum allowable fees.
[2]	The advisor contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, 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.
[3]	The distributor contractually agrees to limit its Rule 12b-1 fees for Class R4 shares to 0.15%. This agreement expires on February 29, 2020, 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.

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> EXPENSE EXAMPLE </b></div>

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

Expense Example - (John Hancock Balanced Fund) - - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	603	822	1,060	1,740

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> PORTFOLIO TURNOVER </b></div>

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 58% of the average value of its portfolio.

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> PRINCIPAL INVESTMENT STRATEGIES </b></div>

Under normal market conditions, the fund invests at least 25% of assets in equity securities and at least 25% of assets in senior debt securities. The fund allocates its investments among a diversified mix of debt and equity securities, including securities of other investment companies that invest in debt and equity securities.

For the equity portfolio, the manager looks for companies that appear to be undervalued compared to their historical valuations relative to the market. The manager uses fundamental financial analysis and proprietary financial models to identify companies of any size that are selling at a discount as measured by ratios such as price-to-book, price-to-earnings, and price-to-sales.

The manager then looks for a positive catalyst in a company's near-term outlook that it believes will accelerate earnings or improve value of the company's assets. These positive catalysts may include, but are not limited to, new, improved, or unique products or services; new or rapidly expanding markets for the company's products; new management; changes in the economic, financial, political, or regulatory environment affecting the company; or a business strategy not recognized by the marketplace. The manager also considers an issuer's dividend-paying prospects and overall financial strength.

The fund's debt portfolio is intended to enhance current income and provide added stability. The fund may invest in bonds of any maturity. The fund's bond investments are primarily rated investment-grade (rated BBB or above by Standard & Poor's Ratings Services or Baa or above by Moody's Investors Service, Inc. and unrated equivalents). Up to 20% of assets may be invested in below-investment-grade bonds (i.e., junk bonds) rated as low as C by Standard & Poor's Ratings Services or Moody's Investors Service, Inc. and their unrated equivalents. The fund's investment policies are based on credit ratings at the time of purchase.

Although the fund invests primarily in U.S. securities, it may invest up to 35% of assets in foreign securities. The fund may invest up to 50% of assets in mortgage-backed securities. The fund may trade securities actively.

The fund may engage in derivatives transactions to a limited extent. Derivatives may be used to reduce risk and/or obtain efficient market exposure, and may include futures contracts, options, and foreign currency forward contracts.

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> PRINCIPAL RISKS </b></div>

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

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

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

Credit and counterparty risk. The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.

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

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

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

Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.

Foreign securities risk. Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.

Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivative transactions. Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, and options. Foreign currency forward contracts, futures contracts, and options generally are subject to counterparty risk. Derivatives associated with foreign currency transactions are subject to currency risk.

High portfolio turnover risk. Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.

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

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

Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.

Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.

Mortgage-backed and asset-backed securities risk. Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.

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

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> PAST PERFORMANCE </b></div>

The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The Bloomberg Barclays U.S. Aggregate Bond Index and the 60% S&P 500 Index/40% Bloomberg Barclays U.S. Aggregate Bond Index represent broad measures of the U.S. stock and bond markets, respectively, and show how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A, Class B and Class C), Monday to Thursday, 8:00 A.M.—7:00 P.M., and Friday, 8:00 A.M.—6:00 P.M., Eastern time, or 888-972-8696 (Class I and Class R suite) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.

A note on performance

Class A, Class R6, and Class R2 shares commenced operations on October 5, 1992, September 1, 2011, and March 1, 2012, respectively. Returns prior to a class's commencement date are those of Class A shares, except that they do not include sales charges and would be lower if they did. Returns for Class R2 and Class R6 shares would have been substantially similar to returns of Class A shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

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