Past performance is no guarantee of future results. You can purchase or sell common shares daily. Like any other stock, market price will fluctuate with the market. Upon sale, your shares may have a market price that is above or below net asset value and may be worth more or less than your original investment. Due to ongoing market volatility, performance is subject to substantial short-term fluctuations.

The Funds invest in lower-rated fixed-income securities, often referred to as "junk bonds," which generally present greater risks than higher quality securities, because of the greater likelihood that the company issuing the lower-rated securities will default on income and principal payments. Shares of closed-end funds frequently trade at a market price that is below their net asset value.
