four rating categories by nationally
recognized statistical rating organizations such as Moody’s Ratings or S&P Global Ratings (S&P). If two or more nationally recognized statistical rating organizations have assigned different ratings to a security, the
investment adviser uses the highest rating assigned. The Fund may also invest in unrated securities, in which case the investment adviser may internally assign ratings to certain of those securities, after assessing their credit
quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the investment
adviser’s credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization. Although the Fund normally invests a substantial portion of its assets in
lower-grade, high-yield debt securities, it can buy investment-grade debt securities without limit. The Fund may also invest in certain restricted securities and securities exempt from registration under the Securities Act of
1933 (Securities Act) including securities that are only eligible for resale pursuant to Rule 144A under the Securities Act (referred to as Rule 144A Securities). The Fund may also invest in exchange-traded funds and other investment
companies.
The Fund can enter into “forward roll” transactions (also referred to as
“mortgage dollar rolls”) with respect to mortgage-related securities. A substantial
portion of the Fund’s assets may be subject to forward roll transactions at any given time.
The Fund may also use derivatives for investment purposes or to manage
investment risks, including options, futures, forward contracts, swaps and “structured” notes. The Fund actively manages foreign currency exposure, to seek to both reduce risk and enhance return. To do so, the Fund may invest in foreign exchange
derivatives, including forwards and options that reference foreign currencies, including currencies of developing and emerging market countries.
The portfolio managers analyze the overall investment opportunities and
risks across global fixed income markets in which the Fund invests and seek to moderate the
special risks of investing in lower-grade, high-yield debt instruments and foreign securities by building a broadly diversified portfolio. The Fund’s diversification strategies are intended to help reduce share price volatility
while seeking current income. The portfolio managers currently focus on securities that they believe offer a balance of income and total return, securities whose market prices tend to move in different directions (to seek overall portfolio
diversification), and relative values across global fixed income markets. These factors may vary in particular cases and may change over time. The Fund may sell securities that the portfolio managers believe are no longer favorable
with regard to these factors.
The Fund may invest up to 25% of its total assets in
a Cayman Islands exempted company that is wholly-owned and controlled by the Fund (the
Subsidiary). The Subsidiary invests in Regulation S securities. Regulation S securities are
securities of U.S. and non-U.S. issuers that are issued through private offerings without registration with the Securities and Exchange Commission pursuant to Regulation S under the Securities Act of 1933. The Fund applies its investment
restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments
described in this prospectus, the Fund may be considered to be investing indirectly in those investments through its Subsidiary. Therefore, references in this prospectus to investments by the Fund also may be deemed to include
the Fund’s indirect investments through the Subsidiary.
In attempting to meet its investment objective or to manage subscription
and redemption requests, the Fund may engage in active and frequent trading of portfolio securities.
Principal Risks of Investing in the Fund
As with any
mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other
governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund
are:
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will
go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may
go up or down due to general market conditions that are not specifically related to the particular issuer. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or
economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters,
widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in particular, such as when the U.S.
economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Fund has exposure. Increasingly strained relations
between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
During a general downturn in the financial markets, multiple asset classes
may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An
increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will
cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating
rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a
timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The credit analysis applied to the
Fund’s debt securities may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Changing Fixed Income Market Conditions Risk. Increases in the
federal funds and equivalent foreign rates or other changes to monetary policy or regulatory
actions may expose fixed income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed income investments, particularly those with longer maturities. Such changes and
resulting increased volatility may adversely impact the Fund, including its operations, universe of potential investment options, and return potential. It is difficult to predict the impact of interest rate changes on various
markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund’s
investments and share price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and
confidence in the financial markets, which could result in higher than normal redemptions by shareholders, which could potentially increase the Fund’s portfolio turnover rate and transaction costs.
Mortgage- and Asset-Backed Securities Risk. Mortgage- and
asset-backed securities, including collateralized debt obligations and collateralized mortgage
obligations, are subject to prepayment or call risk,
