Morgan Stanley currently invests and plans to continue
to invest on its own behalf and on behalf of its Affiliated Investment Accounts in a wide variety of investment opportunities globally.
Morgan Stanley and its Affiliated Investment Accounts, to the extent consistent with applicable law and policies and procedures, will
be permitted to invest in investment opportunities without making such opportunities available to a Fund. Subject to the foregoing, Morgan
Stanley may offer investments that fall into the investment objectives of an Affiliated Investment Account to such account or make such
investment on its own behalf, even though such investment also falls within a Fund’s investment objectives. A Fund may invest in
opportunities that Morgan Stanley and/or one or more Affiliated Investment Accounts has declined, and vice versa. All of the foregoing
may reduce the number of investment opportunities available to a Fund and may create conflicts of interest in allocating investment opportunities.
Investors should note that the conflicts inherent in making such allocation decisions may not always be resolved to a Fund’s advantage.
There can be no assurance that a Fund will have an opportunity to participate in certain opportunities that fall within their investment
objectives. The interests of Morgan Stanley in an investment or a company may present certain conflicts of interest with respect to an
investment by a Fund in the same investment or a Fund’s participation in a transaction with such company.

when not utilizing such techniques. This could create conflicts of interest, and it is possible that one or more accounts managed by the
Adviser will achieve investment results that are substantially more or less favorable than those results achieved by a Fund.

To seek to reduce potential conflicts of interest and
to attempt to allocate such investment opportunities in a fair and equitable manner, the Adviser has implemented allocation policies and
procedures. These policies and procedures are intended to give all clients of the Adviser, including the Fund, fair access to investment
opportunities consistent with the requirements of organizational documents, investment strategies, applicable laws and regulations, and
the fiduciary duties of the Adviser. Each client of the Adviser that is subject to the allocation policies and procedures, including each
Fund, is assigned an investment team and portfolio manager(s) by the Adviser. The investment team and
