Effective June 21, 2023, the Fund changed its name from Morgan Stanley Institutional Fund Sustainable Emerging Markets Portfolio to Morgan Stanley Institutional Fund Emerging Markets ex China Portfolio, and modified its non-fundamental investment policy to reflect that, under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in equity securities of issuers located in emerging market countries excluding China and Hong Kong.

Class C shares include deferred sales charge of 1.00% which declines to zero after first year.

Where the net expense ratio is lower than the gross expense ratio, certain fees have been waived and/ or expenses reimbursed. These waivers and/or reimbursements will continue for at least one year from the date of the applicable fund’s current prospectus (unless otherwise noted in the applicable prospectus) or until such time as the fund's Board of Directors acts to discontinue all or a portion of such waivers and/or reimbursements. Absent such waivers and/or reimbursements, returns would have been lower. Expenses are based on the fund's current prospectus. The minimum initial investment is $1,000,000 for Class I shares.

Class R6 shares, are  being offered only to eligible investors who must meet a minimum initial investment of $5,000,000 or be a defined contribution, defined benefit or other employer sponsored employee benefit plan, whether or not qualified under the Internal Revenue Code of 1986, as amended (the "Code"), in each case subject to the discretion of the Portfolio's investment advisor.

PORTFOLIO CHARACTERISTICS DEFINITIONS
Active share is the fraction of the portfolio or fund that is invested differently than its benchmark as of the last day of the reporting period. Number of holdings provided are a typical range, not a maximum number. The portfolio may exceed this from time to time due to market conditions and outstanding trades. Price/book compares a stock's market value to the book value per share of total assets less total liabilities. This number is used to judge whether a stock is undervalued or overvalued. Price/cash flow is a ratio used to compare a company's market value to its cash flow. It is calculated by dividing the company's per-share stock price by the per-share operating cash flow. Price/earnings (LTM) is the price of a stock divided by its earnings per share for the past 12 months. Sometimes called the multiple, P/E gives investors an idea of how much they are paying for a company’s earning power. Return on equity (ROE) is the amount of net income returned as a percentage of shareholders equity. Weighted average market capitalization is an average of the market capitalization of stocks held by a portfolio or comprising an index, adjusted by each stock’s corresponding weight in the portfolio or index. Weighted median market capitalization is the point at which half of the market value of a portfolio or index is invested in stocks with a greater market capitalization, and consequently the other half of the market value is invested in stocks with a lower market capitalization 

RISK CONSIDERATIONS
There is no assurance that a portfolio will achieve its investment objective. Portfolios are subject to market risk, which is the possibility that the market values of securities owned by the portfolio will decline. Market values can change daily due to economic and other events (e.g. natural disasters, health crises, terrorism, conflicts and social unrest) that affect markets, countries, companies or governments. It is difficult to predict the timing, duration, and potential adverse effects (e.g. portfolio liquidity) of events. Accordingly, you can lose money investing in this strategy. Please be aware that this strategy may be subject to certain additional risks. In general, equities securities’ values also fluctuate in response to activities specific to a company. Investments in foreign markets entail special risks such as currency, political, economic, market and liquidity risks. The risks of investing in emerging market countries are greater than the risks generally associated with investments in foreign developed countries. Derivative instruments can be illiquid, may disproportionately increase losses and may have a potentially large negative impact on the portfolio’s performance. Illiquid securities may be more difficult to sell and value than publicly traded securities (liquidity risk). Strategies that incorporate impact investing and/or Environmental, Social and Governance (ESG) factors could result in relative investment performance deviating from other strategies or broad market benchmarks, depending on whether such sectors or investments are in or out of favor in the market. As a result, there is no assurance strategies that incorporate ESG factors could result in more favorable investment performance.

Morningstar
Rankings: The percentile rankings are based on the average annual total returns for the periods stated and do not include any sales charges, but do include reinvestment of dividends and capital gains and Rule 12b-1 fees. The highest (or most favorable) percentile rank is 1 and the lowest (or least favorable) percentile rank is 100. The top-performing fund in a category will always receive a rank of 1.

Ratings: The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. Ratings do not take into account sales loads.
