 reviewed and updated as necessary to address new and evolving proxy voting issues
and standards.

The MSIM entities covered by this Policy currently include the following:
Morgan Stanley AIP GP LP, Morgan Stanley Investment Management Inc., Morgan Stanley Investment Management Limited, Morgan Stanley Investment
Management Company, Morgan Stanley Saudi Arabia, MSIM Fund Management (Ireland) Limited, Morgan Stanley Asia Limited, Morgan Stanley
Investment Management (Japan) Co. Limited, Morgan Stanley Investment Management Private Limited, Morgan Stanley Eaton Vance CLO Manager
LLC, and Morgan Stanley Eaton Vance CLO CM LLC (each an "MSIM Affiliate" and collectively referred to as the "MSIM
Affiliates" or as "we" below).

Each MSIM Affiliate will use its best efforts to vote proxies as part
of its authority to manage, acquire and dispose of account assets.

| · | With respect to the U.S. registered investment companies sponsored, managed or advised by any MSIM Affiliate (the "MS Funds"),           
 each MSIM Affiliate will vote proxies under this Policy pursuant to authority granted under its applicable investment advisory agreement 
 or, in the absence of such authority, as authorized by the Board of Directors/Trustees of the MS Funds.                                  |

| · | For other pooled investment vehicles (e.g., UCITS), each MSIM Affiliate will vote proxies under this Policy pursuant to authority        
 granted under its applicable investment advisory agreement or, in the absence of such authority, as authorized by the relevant governing 
 board.                                                                                                                                   |

| · | For separately managed accounts (including ERISA and ERISA-equivalent clients), each MSIM Affiliate will vote proxies under this Policy      
 pursuant to authority granted under the applicable investment advisory agreement or investment management agreement. Where an MSIM Affiliate 
 has the authority to vote proxies on behalf of ERISA and ERISA-equivalent clients, the MSIM Affiliate must do so in accordance with its      
 fiduciary duties under ERISA (and the Internal Revenue Code).                                                                                |

| · | In certain situations, a client or its fiduciary may reserve the authority to vote proxies for itself or an outside party or may provide 
 an MSIM Affiliate with a statement of proxy voting policy. The MSIM Affiliate will comply with the client's policy.                      |

| · | Certain ETFs will follow Calvert’s Global Proxy Voting Guidelines set forth in Appendix A of Calvert’s Proxy Voting Policies       
 and Procedures and the proxy voting guidelines discussed below do not apply to such ETFs. See Appendix A of Calvert
