The two main risks related with bond investing are interest rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments. Historically, traditional bond funds have been dominated by interest rate risk. Flexible bond strategies, like the Fund's, have the ability to actively manage the level of interest rate risk and assume more credit risk through exposure to securities such as high yield bonds, securitized assets and foreign debt.

Volatility refers to annualized standard deviation of daily returns for the trailing 30 days. Standard deviation is a measure of the dispersion of an investment's actual returns compared to its expected returns. Standard deviation is only one element of risk. Other risk factors should be considered.

Since inception, the Fund has had a correlation of -0.19 to the Bloomberg Barclays US Aggregate Bond Index as of 6/30/18.
