|
FUND STRATEGY The Fund seeks to maximize total return through a combination of income and capital appreciation. Drawing on the expertise of Pioneer's global bond investment team, the Fund's management constructs a diversified portfolio of below-investment-grade (high yield) debt securities and preferred stocks of U.S. and non-U.S. securities, including those from emerging markets. |
PORTFOLIO MANAGEMENT PERSPECTIVE
"We believe that a flexible approach to high-yield investing through investment in U.S. high yield, international high yield and emerging market bonds enables us to achieve superior returns and lower undue risk as compared with an average high yield portfolio. We seek to stay diversified across countries/regions, sectors/industries and currencies and are focused on a value-oriented approach to finding the best investment opportunities."
A WORD ABOUT RISK
Investments in high yield or lower-rated securities are subject to greater-than-average 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. Investing in foreign and/or emerging market securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. 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. 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.

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).
