The performance shown represents past performance and is not a guarantee of future results. Current performance may be lower or higher than the performance data quoted. The investment return and the principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. From time to time the advisor has waived fees or reimbursed expenses, which may have resulted in higher returns. The listed returns and yields on the Fund are net of expenses and the returns and yields on the indices exclude expenses. Current performance of the Fund may be lower or higher than the performance quoted.

Investments in foreign securities, even though publicly traded in the United States, may involve risks which are in addition to those inherent in domestic investments.

The Fund is subject to the risks associated with investments in debt securities, such as default risk and fluctuations in the perception of the debtor's ability to pay its creditors.

Changing interest rates may adversely affect the value of an investment. An increase in interest rates typically causes the value of bonds and other fixed income securities to fall.

Class C shares convert to an equal dollar value of Class A shares at the end of the tenth year after purchase.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating™ based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) The Overall Morningstar Rating for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metric.

Morningstar Rating is for the share class indicated only (see ticker), other share classes may have different performance characteristics. The Ranking may reflect the waiver of all or a portion of the fund's fees. Without such waiver, the Rankings may have been lower.
