Past performance is no assurance of future results. Investment return
and market value of an investment in the Fund will fluctuate. Shares,
when sold, may be worth more or less than their original cost. There can
be no assurance that the Fund’s investment objectives will be achieved.
The Fund may not be appropriate for all investors.

Principal Risk Factors: The Fund invests in non-investment grade debt
instruments, commonly referred to as “high-yield securities”. High-yield
securities are subject to greater market fluctuations and risk of loss
than securities with higher ratings. Lower-quality debt tends to be less
liquid than higher-quality debt.

The debt securities in which the Fund invests are subject to certain
risks, including issuer risk, reinvestment risk, prepayment risk, credit
risk, and interest rate risk. Issuer risk is the risk that the value of
fixed-income securities may decline for a number of reasons which
directly relate to the issuer. Reinvestment risk is the risk that income
from the Fund’s portfolio will decline if the Fund invests the proceeds
from matured, traded or called bonds at market interest rates that are
below the Fund portfolio’s current earnings rate. Prepayment risk is the
risk that, upon a prepayment, the actual outstanding debt on which the
Fund derives interest income will be reduced. Credit risk is the risk
that an issuer of a security will be unable or unwilling to make
dividend, interest and/or principal payments when due and that the value
of a security may decline as a result. Interest rate risk is the risk
that fixed-income securities will decline in value because of changes in
market interest rates.

In times of unusual or adverse market, economic, regulatory or political
conditions, the Fund may not be able, fully or partially, to implement
its short selling strategy. Short selling creates special risks which
could result in increased volatility of returns and may result in
greater gains or greater losses.

The Fund invests in securities of non-U.S. issuers which are subject to
higher volatility than securities of U.S. issuers. Because the Fund
invests in non-U.S. securities, you may lose money if the local currency
of a non-U.S. market depreciates against the U.S. dollar.

The risks of investing in the Fund are spelled out in the shareholder
reports and other regulatory filings.
