Short Duration Income Portfolio

Prior to April 13th, 2020, benchmark data figures were incorrectly over/understated, and have since been corrected.

During calendar years 2016, 2018 and 2019, the MSIFT Short Duration Income Portfolio received monies related to certain nonrecurring litigation settlements. If these monies were not received, any period returns which include these settlement monies would have been lower. For example, the 2019 calendar year returns for Class I Shares were positively impacted by approximately 0.13%, the 2018 calendar year returns by approximately 0.25% and the 2016 calendar year returns by approximately 6.52%. The returns on the other Share Classes would also have been similarly impacted. These were one-time settlements, and as a result, the impact on the net asset value and consequently the performance will not likely be repeated in the future. Rankings for the fund were more favorable due to these settlements and ratings may also have been positively impacted. Please call the toll free number for additional information.

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 Trustees 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.

Class IS shares, are being offered only to eligible investors who must meet a minimum initial investment of $10,000,000 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.

On January 11, 2016, Morgan Stanley ("MS") Limited Duration U.S. Government Trust merged into Morgan Stanley Institutional Fund Trust (“MSIFT”) Limited Duration Portfolio. In conjunction with the merger, MSIFT Limited Duration Portfolio (the Portfolio) was renamed MSIFT Short Duration Income Portfolio and changed its principal investment policy such that under normal circumstances, it seeks  to achieve its investment objective of above-average total return over a market cycle of three to five years by investing substantially all of its assets in investment grade fixed income securities denominated in US dollars, while seeking to maintain an overall duration of its portfolio of approximately one year or less. In addition, the Portfolio changed its benchmark from the Bloomberg Barclays 1-3 Year U.S. Government/Credit Index to the Bank of America/Merrill Lynch 1-Year U.S. Treasury Note Index.

As of the close of business on January 6, 2016, the Portfolio is suspended the continuous offering of its Class C shares and thus, no further purchases of Class C shares of the Portfolio may be made by investors. Existing Class C shareholders may continue to invest through reinvestment of dividends and distributions.

Growth of Investment illustration is based on an initial investment of $10,000 made since fund inception, assumes reinvestment of dividends and capital gains and application of fees, but does not include sales charges. Performance would have been lower if sales charges had been included. Results are hypothetical.

Subject to change daily. Fund information, Portfolio Composition and Characteristics are provided for informational purposes only, and should not be deemed as a recommendation to buy or sell any security or securities in the region presented. 

Returns are net of fees and assume the reinvestment of all dividends and income. Returns for less than one year are cumulative (not annualized). Performance of other share classes will vary.

Please keep in mind that double-digit returns are highly unusual and cannot be sustained. Investors should also be aware that these returns were primarily achieved during favorable market conditions.

DEFINITIONS
SEC yield is a measure of the income generated by the portfolio's underlying asset over the trailing 30 days, relative to the asset base of the portfolio itself. The SEC 30-Day yield - Subsidized (Sub.) reflects current fee waivers in effect. Absent such fee waivers, the yield would have been lower. The SEC 30-Day yield- Unsubsidized (Unsub.) does not reflect the fee waivers currently in effect.

PORTFOLIO CHARACTERISTICS DEFINITIONS 
The Net Asset Value (NAV) per share is determined by dividing the value of the fund's portfolio securities, cash and other assets, less all liabilities, by the total number of common shares outstanding. The common share market price is the price the market is willing to pay for shares of the fund at a given time. Duration is a measure of the sensitivity of the price (the value of principal) of a fixed-income investment to a change in interest rates. Duration is expressed as a number of years. Rising interest rates mean falling bond prices, while declining interest rates mean rising bond prices. 

Turnover is sourced from the fund's current prospectus.

Quality distribution refers to the rating given by a Nationally Recognized Statistical Rating Organization ("NRSRO") and is the rating firms’ subjective opinion concerning the ability and willingness of an issuer to meet its financial obligations in full and on time. Ratings apply only to portfolio holdings and do not remove the Fund’s market risk. Quality distribution data for securities is sourced from Fitch, Moody’s and S&P. Where the credit ratings for individual securities differ between the three ratings agencies, the ‘highest’ rating is applied. The rating of credit default swaps is based on the ‘highest’ rating of the underlying reference bond. ‘Cash’ includes investments in short term instruments, including investments in Morgan Stanley liquidity funds.

RISK/RETURN DEFINITIONS 
Excess Return or value added (positive or negative) is the portfolio’s return relative to the return of the benchmark. Alpha (Jensen's) is a risk-adjusted performance measure that represents the average return on a portfolio or investment above or below that predicted by the capital asset pricing model (CAPM) given the portfolio's or investment's beta and the average market return. Prior to 6/30/2018 Alpha was calculated as the excess return of the fund versus benchmark. Beta is a measure of the relative volatility of a security or portfolio to the market's upward or downward movements.  Information ratio is the portfolio’s alpha or excess return per unit of risk, as measured by tracking error, versus the portfolio’s benchmark. R squared measures how well an investment’s returns correlate to an index. An R squared of 100 means the portfolio performance is 100% correlated to the index’s, whereas a low r-squared means that the portfolio performance is less correlated to the index’s. Sharpe ratio is a risk-adjusted measure calculated as the ratio of excess return to standard deviation. The Sharpe ratio determines reward per unit of risk. The higher the Sharpe ratio, the better the historical risk-adjusted performance. Standard deviation measures how widely individual performance returns, within a performance series, are dispersed from the average or mean value.

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 and that the value of Portfolio shares may therefore be less than what you paid for them. 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 Portfolio. Please be aware that this Portfolio may be subject to certain additional risks. Fixed-income securities are subject to the ability of an issuer to make timely principal and interest payments (credit risk), changes in interest rates (interest-rate risk), the creditworthiness of the issuer and general market liquidity (market risk). In a rising interest-rate environment, bond prices may fall and may result in periods of volatility and increased portfolio redemptions. In a declining interest-rate environment, the portfolio may generate less income. Longer-term securities may be more sensitive to interest rate changes. Mortgage- and asset-backed securities are sensitive to early prepayment risk and a higher risk of default and may be hard to value and difficult to sell (liquidity risk). They are also subject to credit, market and interest rate risks. Foreign securities are subject to currency, political, economic and market risks. The risks of investing in emerging market countries are greater than risks associated with investments in foreign developed countries. Derivative instruments may disproportionately increase losses and have a significant impact on performance. They also may be subject to counterparty, liquidity, valuation, correlation and market risks. Illiquid securities may be more difficult to sell and value than publicly traded securities (liquidity risk). Certain U.S. government securities purchased by the Strategy, such as those issued by Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. It is possible that these issuers will not have the funds to meet their payment obligations in the future.

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.
