The fund seeks to provide maximum total return consistent with capital preservation and prudent risk management by investing primarily in investment-grade corporate debt securities, such as bonds. Normally, at least 80% of the fund’s assets will be invested in corporate debt securities. For purposes of this policy, corporate debt securities include, but are not limited to, bonds, notes, debentures, asset-backed securities (including those backed by mortgages), bank loans, loan participations and assignments, hybrids (securities with equity and debt characteristics), certain preferred securities and commercial paper and other cash equivalents (including shares of money market or similair funds managed by the investment adviser or its affiliates). Investments in derivatives may be counted toward the fund’s 80% investment policy to the extent that such derivatives provide investment exposure to the investments included within the policy or to one or more market risk factors associated with such investments. The fund will also normally invest all of its assets in debt instruments (including bonds, mortgage- and other asset-backed securities) with quality ratings of Baa3 or better or BBB- or better by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser or in debt instruments that are unrated but determined at the time of purchase to be of equivalent quality by the fund’s investment adviser. However, the fund may invest in debt securities guaranteed or sponsored by the U.S. government, as well as debt issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government, without regard to the quality rating assigned to the U.S. government by a Nationally Recognized Statistical Rating Organization. Additionally, the fund may invest in cash, and cash equivalents (including shares of money market or similar funds managed by the investment adviser or its affiliates). The fund may also invest in derivatives instruments (but excluding any derivatives instruments that are rated below Baa3 and BBB- by Nationally Recognized Statistical Rating Organizations designated by the fund's investment adviser or are unrated but determined at the time of purchase to be of equivalent quality by the fund’s investment adviser).

The fund may invest significantly in debt securities tied economically to countries outside the United States, including developing countries. All securities held by the fund will be denominated in U.S. dollars.

The fund may invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

Market conditions — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund’s investments may be negatively affected by developments in other countries and regions.

Investing in debt instruments — The prices of, and the income generated by, bonds and other debt securities held by the fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker,

and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund’s securities could cause the value of the fund’s shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which the fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund’s investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.

Investing in derivatives — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may cause the fund to lose significantly more than its initial investment. Derivatives may be difficult to value, difficult for the fund to buy or sell at an opportune time or price and difficult, or even impossible, to terminate or otherwise offset. The fund’s use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund’s returns and increase the fund’s price volatility. The fund’s counterparty to a derivative transaction (including, if applicable, the fund’s clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction. In certain cases, the fund may be hindered or delayed in exercising remedies against or closing out derivative instruments with a counterparty, which may result in additional losses. Derivatives are also subject to operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

Investing outside the United States — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States and securities tied economically to countries outside the United States may lose value because of adverse political, social, economic or market developments in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, auditing, financial reporting, accounting and recordkeeping standards and practices, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund’s portfolio.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
