If you have not yet cast your important proxy vote, please do so today. We’ve enclosed another copy of your proxy card(s) for your convenience.  Please vote before the adjourned meeting on July 26, 2023.

Stockholders of each Fund are being asked to consider and vote to approve proposal(s) relating to an Agreement and Plan of Reorganization which is fully detailed in the Joint Proxy Statement/Prospectus. For more important information, including the potential benefits associated with the proposed reorganizations, please refer to the Joint Proxy Statement/Prospectus, which can be found at https://vote.proxyonline.com/nb/docs/2023proxy.pdf and can be accessed through the Securities and Exchange Commission’s website at www.sec.gov.

Each Fund’s Board of Directors believes that the proposal(s) are in the best interests of its Fund’s stockholders and recommends that stockholders vote “FOR” the proposal(s).
