FUND STRATEGY The Fund seeks high current income by actively managing a diversified portfolio of U.S. and international high yield and investment-grade debt securities. It selects sector concentrations driven by evaluation of capital markets. The Fund actively adjusts a blend of fixed-income securities to manage risk, enhance yield, and offer total return potential. |
PORTFOLIO MANAGEMENT PERSPECTIVE
"In-depth, bottom-up research, timely asset allocation, and well-diversified bond asset classes are the foundation of our portfolio construction and security selection process. We believe this approach allows higher yields and higher returns than a core bond strategy alone allows without increased risk."
Fund commentary with performance analysis
A WORD ABOUT RISK
When interest rates rise, the prices of fixed-income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities in the Fund will generally rise. Investments in the Fund are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. The securities issued by U.S. Government sponsored entities (i.e., FNMA, Freddie Mac) are neither guaranteed nor issued by the U.S. Government. The portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed-income securities. Mortgage-backed securities are also subject to pre-payments. Investments in high yield or lower-rated securities are subject to greater-than-average risk. Investing in foreign and/or emerging market securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility.

The 30-day SEC yield is based on the hypothetical annualized earning power (investment income only) of the Fund's portfolio securities during the period indicated.
The Average Maturity of certain funds might not be a useful measure if they contain securities with principal paydowns, such as mortgage passthroughs. Instead, market participants calculate Average Life, which reflects the average time to receipt of principal payments (scheduled principal payments and projected prepayments).
