The new regular monthly distribution for AGC will be $0.047 per share. This new monthly distribution compares to $0.0664 per share for the Fund's most recent distribution. The new regular quarterly distribution for LCM will be $0.210 per share. This new quarterly distribution compares to $0.264 per share for the Fund's most recent distribution. The modifications were made in an effort to more closely align the earnings potential of the Funds' investments with the distribution rates of each Fund while also seeking to provide investors with greater long-term total return potential. Lower interest rates in U.S. Treasuries, high yield, investment grade and convertible securities have also influenced this decision.
