AB Income Fund 

Effective April 18, 2016, the Fund ceased trading as a closed-end fund and began operations as an open-end fund on April 25, 2016. While the investment guidelines of the open-end fund are similar to the guidelines of the closed-end fund, a closed-end fund does not have to manage to liquidity in the same fashion as an open-end fund, and the closed-end fund had the ability for greater leverage than an open-end fund. Additionally, the investment universe was broadened from 65% in US government bonds to 65% in bonds of US and foreign governments and at least 65% in US dollar-denominated bonds. We believe the structure of the Fund maintains a balanced exposure to high quality government bonds as well as credit, and will lead to diversification and new investment opportunities.
