(1)

For investments over $1 million, a 1.00% maximum deferred sales charge may apply.

(2)

"Management fees" have been restated to reflect current fees.

(3)

"Other expenses" for Class I and Y have been restated to reflect the estimated transfer agency fees for the current year.

(4)

"Total annual fund operating expenses" do not correlate to the ratio of expenses to average net assets that is disclosed in the Fund’s annual report in the financial highlights table, which reflects the operating expenses of the Fund and does not include acquired fund fees and expenses. The ratio of expenses to average net assets that is disclosed in the Fund’s annual report in the financial highlights table for the applicable period also does not reflect the restated "Management fees" or "Other expenses" for Class I and Y.

Example.  The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

•

You invest $10,000

•

Your investment has a 5% return each year

•

The Fund’s operating expenses remain the same

•

You reinvest all dividends and distributions

•

You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

Share Classes	Year 1			Year 3			Year 5			Year 10

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 examples, affect the Fund’s performance. During the fiscal year ended October 31, 2019, the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

Principal Investment Strategy. Under normal circumstances, the Fund invests at least 80% of its assets in bonds that the sub-adviser, Wellington Management Company LLP ("Wellington Management"), considers to be attractive from a total return perspective along with current income. The Fund may invest up to 20% of its net assets in securities rated below investment grade (also known as “junk bonds”).

Bonds in which the Fund invests include (1) securities issued or guaranteed as to principal or interest by the U.S. Government, its agencies or instrumentalities; (2) non-convertible debt securities issued or guaranteed by U.S. corporations or other issuers (including foreign governments or corporations); (3) asset-backed and mortgage-related securities, including collateralized loan obligations; and (4) securities issued or guaranteed as to principal or interest by a sovereign government or one of its agencies or political subdivisions, supranational entities such as development banks, non-U.S. corporations, banks or bank holding companies, or other foreign issuers.

The Fund may use derivatives to manage portfolio risk or for other investment purposes. The derivatives in which the Fund may invest include, but are not limited to, futures and options contracts, swap agreements and forward foreign currency contracts. Additionally, the Fund may invest up to 40% of its net assets in debt securities of foreign issuers, including from emerging markets, and up to 20% of its net assets in non-dollar securities. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis, including securities acquired or sold in the “to be announced” (TBA) market. The Fund may invest in “Rule 144A” securities, which are privately placed, restricted securities that may only be resold under certain circumstances to other qualified institutional buyers. The Fund may trade securities actively. Although the Fund may invest in securities and other instruments of any maturity or duration, the Fund normally invests in debt securities with a maturity of at least one year. There is no limit on the average maturity of the Fund’s portfolio.

The investment team is organized with generalist portfolio managers leading sector, rates and risk positioning decisions. The portfolio managers may allocate a portion of the Fund’s assets to specialists within Wellington Management who drive individual sector and security selection strategies.

PRINCIPAL RISKS. The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. 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. As with any fund, there is no guarantee that the Fund will achieve its investment objective.

Market Risk −Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets.

Interest Rate Risk −The risk that your investment may go down in value when interest rates rise, because when interest rates rise, the prices of bonds and fixed rate loans fall. A wide variety of factors can cause interest rates to rise, including central bank monetary policies and inflation rates. Generally, the longer the maturity of a bond or fixed

3​

rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund’s income. These risks are greater during periods of rising inflation. Volatility in interest rates and in fixed income markets may increase the risk that the Fund’s investment in fixed income securities will go down in value. Risks associated with rising interest rates are currently heightened because interest rates in the U.S. remain near historic lows and the Federal Reserve Board may raise interest rates. Actions taken by the Federal Reserve Board or foreign central banks to stimulate or stabilize economic growth, such as decreases or increases in short-term interest rates, may adversely affect markets, which could, in turn, negatively impact Fund performance.

Credit Risk −Credit risk is the risk that the issuer of a security or other instrument will not be able to make principal and interest payments when due. Changes in an issuer’s financial strength, credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

Mortgage-Related and Asset-Backed Securities Risk −Mortgage-related and asset-backed securities represent interests in “pools” of assets. These securities are subject to credit risk, interest rate risk, “prepayment risk” (the risk that borrowers will repay a loan more quickly in periods of falling interest rates) and “extension risk” (the risk that borrowers will repay a loan more slowly in periods of rising interest rates). The value of these securities will be influenced by factors affecting the assets underlying such securities. If the Fund invests in mortgage-related or asset-backed securities that are subordinated to other interests in the same asset pool, the Fund may only receive payments after the pool’s obligations to other investors have been satisfied. During periods of difficult or frozen credit markets, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may limit substantially the pool’s ability to make payments of principal or interest to the Fund, reducing the values of those securities or in some cases rendering them worthless. The risk of such defaults is generally higher in the case of mortgage pools that include so-called “subprime” mortgages.

Collateralized Loan Obligations Risk −Collateralized loan obligations (“CLOs”) bear many of the same risks as other forms of asset-backed securities. As they are backed by pools of loans, CLOs also bear similar risks to investing in loans directly. CLOs may experience substantial losses attributable to loan defaults. Losses caused by defaults on underlying assets are borne first by the holders of subordinate tranches. The Fund’s investment in CLOs may decrease in market value when the CLO experiences loan defaults or credit impairment, the disappearance of a subordinate tranche, or market anticipation of defaults and investor aversion to CLO securities as a class.

To Be Announced (TBA) Transactions Risk −TBA investments include when-issued and delayed delivery securities and forward commitments. TBA transactions involve the risk that the security the Fund buys will lose value prior to its delivery. The Fund is subject to this risk whether or not the Fund takes delivery of the securities on the settlement date for a transaction. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price. The Fund may also take a short position in a TBA investment when it owns or has the right to obtain, at no added cost, identical securities. If the Fund takes such a short position, it may reduce the risk of a loss if the price of the securities declines in the future, but will lose the opportunity to profit if the price rises.

Derivatives Risk −Derivatives are instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Successful use of derivative instruments by the Fund depends on the sub-adviser’s judgment with respect to a number of factors and the Fund’s performance could be worse and/or more volatile than if it had not used these instruments. In addition, the fluctuations in the value of derivatives may not correlate perfectly with the value of any portfolio assets being hedged, the performance of the asset class to which the sub-adviser seeks exposure, or the overall securities markets.

Leverage Risk −Certain transactions, such as the use of derivatives, may give rise to leverage. Leverage can increase market exposure, increase volatility in the Fund, magnify investment risks, and cause losses to be realized more quickly. The use of leverage may cause the Fund to liquidate portfolio positions to satisfy its obligations or to meet asset segregation requirements when it may not be advantageous to do so.

Swaps Risk −A swap is a two-party contract that generally obligates the parties to exchange payments based on a specified reference security, basket of securities, security index or index component. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Certain swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

4

Futures and Options Risks −Futures and options may be more volatile than direct investments in the securities underlying the futures and options, may not correlate perfectly to the underlying securities, may involve additional costs, and may be illiquid. Futures and options also may involve the use of leverage as the Fund may make a small initial investment relative to the risk assumed, which could result in losses greater than if futures or options had not been used. Futures and options are also subject to the risk that the other party to the transaction may default on its obligation.

Forward Currency Contracts Risk −A forward currency contract is an agreement between two parties to buy and sell a currency at a set price on a future date. The market value of a forward currency contract fluctuates with changes in foreign currency exchange rates. While forward foreign currency exchange contracts do not eliminate fluctuations in the value of foreign securities, they do allow the Fund to establish a fixed rate of exchange for a future point in time. Use of such contracts, therefore, can have the effect of reducing returns and minimizing opportunities for gain. The Fund could also lose money when the contract is settled. The Fund’s gains from its positions in forward foreign currency contracts may accelerate and/or recharacterize the Fund’s income or gains and its distributions to shareholders as ordinary income. The Fund’s losses from such positions may also recharacterize the Fund’s income and its distributions to shareholders and may cause a return of capital to Fund shareholders. Such acceleration or recharacterization could affect an investor’s tax liability.

Foreign Investments Risk −Investments in foreign securities may be riskier, more volatile, and less liquid than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions and the U.S. (including the imposition of sanctions, tariffs, or other governmental restrictions), may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments. The impact of the United Kingdom’s departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.

Emerging Markets Risk −The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Currency Risk −The risk that the value of the Fund’s investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer’s local currency.

High Yield Investments Risk −High yield investments rated below investment grade (also referred to as “junk bonds”) are considered to be speculative and are subject to heightened credit risk, which may make the Fund more sensitive to adverse developments in the U.S. and abroad. Lower rated debt securities generally involve greater risk of default or price changes due to changes in the issuer’s creditworthiness than higher rated debt securities. The market prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. There may be little trading in the secondary market for particular debt securities, which may make them more difficult to value or sell.

U.S. Government Securities Risk −Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Securities backed by the U.S. Treasury or the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Obligations of U.S. Government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so. In addition, the value of U.S. Government securities may be affected by changes in the credit rating of the U.S. Government. U.S. Government securities are also subject to the risk that the U.S. Treasury will be unable to meet its payment obligations.

Restricted Securities Risk −Restricted securities are subject to the risk that they may be difficult to sell at the time and price the Fund prefers.

5​

Call Risk −Call risk is the risk that an issuer, especially during a period of falling interest rates, may redeem a security by repaying it early, which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates.

Liquidity Risk −The risk that the market for a particular investment or type of investment is or becomes relatively illiquid, making it difficult for the Fund to sell that investment at an advantageous time or price. Illiquidity may be due to events relating to the issuer of the securities, market events, rising interest rates, economic conditions or investor perceptions. Illiquid securities may be difficult to value and their value may be lower than the market price of comparable liquid securities, which would negatively affect the Fund's performance.

Event Risk −Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.

Active Investment Management Risk −The risk that, if the sub-adviser’s investment strategy, including allocating assets to specialist portfolio managers, does not perform as expected, the Fund could underperform its peers or lose money. The investment styles employed by the specialist portfolio managers may not be complementary, which could adversely affect the performance of the Fund.

Securities Lending Risk −The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Active Trading Risk −Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

Large Shareholder Transaction Risk −The Fund may experience adverse effects when certain large shareholders redeem or purchase large amounts of shares of the Fund. Such redemptions may cause the Fund to sell securities at times when it would not otherwise do so or borrow money (at a cost to the Fund), which may negatively impact the Fund's performance and liquidity. Similarly, large purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks. For more information regarding risks and investments, please see “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.

TAX INFORMATION. The Fund’s distributions are generally taxable, and may be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Such tax-deferred arrangements may be taxed later upon withdrawal of monies from those arrangements.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES. If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial advisor to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary’s website for more information.
