D Proxy Voting Oversight

The Proxy Review Committee (“PRC”) has overall responsibility
for this Policy. The PRC consists of investment professionals who represent the different investment disciplines and/or geographic locations
of MSIM and members of the GST. Additionally, the GST administers and implements the Policy through consultation with PRC members and
MSIM investment teams, as well as monitors services provided by the Proxy Service Providers and any other research providers used in the
proxy voting process.

E. Securities Lending

Accounts or funds sponsored, managed, or advised by MSIM may participate
in a securities lending program through a third-party provider. The voting rights for shares that are out on loan are transferred to the
borrower and therefore, the lender is not entitled to vote the lent shares at the company meeting.

However, in certain circumstances a portfolio manager may seek to recall
shares for the purposes of voting. In this event, the handling of such recall requests would be on a reasonable efforts basis.

F. Market and Operational Limitations

Voting proxies of companies located in some jurisdictions may involve
several issues that can restrict or prevent the ability to vote such proxies or entail significant costs. These issues include, but are
not limited to: (i) proxy statements and ballots being written in a language other than English; (ii) untimely and/or inadequate notice
of shareholder meetings; (iii) restrictions on the ability of holders outside the issuer’s jurisdiction of the listing organization
to exercise votes; (iv) requirements to vote proxies in person; (v) the imposition of restrictions on the sale of the securities for a
period of time in proximity to the shareholder meeting; and (vi) requirements to provide local agents with power of attorney to facilitate
our voting instructions.

As a result, MSIM will use reasonable efforts to vote clients’
non-U.S. proxies, after weighing the costs and benefits of voting such proxies, consistent with the Client Proxy Standard.
