(the “ARNs”)

This document supplements the Note Prospectus in connection with any secondary market transactions in the ARNs by Merrill Lynch, Pierce, Fenner & Smith Incorporated and its affiliates. Capitalized terms used but not defined in this supplement have the meanings set forth in the Note Prospectus.

The Starting Value for the ARNs was defined in the final term sheet (the “Final Term Sheet”), dated October 24, 2013 and filed with the Securities and Exchange Commission (the “SEC”) on October 28, 2013. The Starting Value was defined as the lowest closing level of the Market Measure on any Market Measure Business Day during the Starting Value Determination Period on which a Market Disruption Event has not occurred. The closing level of the Market Measure on October 24, 2013, the first day of the Starting Value Determination Period, was 1,752.07.

The Starting Value Determination Period expired on December 24, 2013. The lowest closing level of the Market Measure on any Market Measure Business Day during the Starting Value Determination Period on which a Market Disruption Event did not occur was 1,747.15, which was the closing level of the Market Measure on November 7, 2013. This closing level is less than 1,752.07.

Therefore, the Starting Value for the ARNs is 1,747.15.
