This table describes the fees and expenses that you may pay if you buy and hold
Fund shares.

SHAREHOLDER FEES (fees paid directly from your investment)

Shareholder Fees	SIMT Real Return Fund Class I
Redemption Fee (applies to a redemption, or series of redemptions, from a single identifiable source that, in the aggregate, exceeds $10 million within any thirty (30) day period)	0.25%

ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		SIMT Real Return Fund Class I
Management Fees		0.22%

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
SIMT Real Return Fund Class I	113	353	612	1,352

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Fund
shares are held in a taxable account. These costs, which are not reflected in
annual Fund operating expenses or in the Example, affect the Fund's performance.
During the most recent fiscal year, the Fund's portfolio turnover rate was 77%
of the average value of its portfolio.

Principal Investment Strategies

The Real Return Fund uses a multi-manager approach under the general supervision
of SIMC, which allocates the Fund's assets among multiple Sub-Advisers using
different investment strategies designed to produce a total return that exceeds
the rate of inflation in the U.S.

Under normal circumstances, the Fund will invest a significant portion of its
assets in investment grade fixed income securities, including inflation-indexed
bonds of varying maturities issued by the U.S. Treasury, other U.S. Government
agencies and instrumentalities and non-government entities, such as
corporations. An inflation-indexed bond is a bond that is structured so that its
principal value will change with inflation. Treasury Inflation Protected
Securities (TIPS) are a type of inflation-indexed bond in which the Fund may
invest.

The Fund may also invest in futures contracts, options, forward contracts and
swaps for risk management purposes, speculative or hedging purposes or as part
of its investment strategies. Futures contracts, forward contracts and swaps are
used to synthetically obtain exposure to securities or baskets of securities and
to manage the Fund's interest rate duration and yield curve exposure. These
derivatives are also used to mitigate the Fund's overall level of risk and/or
the Fund's risk to particular types of securities or market segments. Interest
rate swaps are further used to manage the Fund's yield spread sensitivity.
Securities index swaps are used to manage the inflation-adjusted return of the
Fund.

The Fund may also invest in other financial instruments or use other investment
techniques (such as reverse repurchase agreements) to seek to obtain market
exposure to the securities in which the Fund primarily invests.

The Fund may also invest in: (i) securities issued or guaranteed by the U.S.
Government and its agencies and instrumentalities and obligations of U.S. and
foreign commercial banks, such as certificates of deposit, time deposits,
bankers' acceptances and bank notes; (ii) obligations of foreign governments;
(iii) U.S. and foreign corporate debt securities, including commercial paper,
and fully-collateralized repurchase agreements with highly rated counterparties
(those rated A or better); and (iv) securitized issues such as mortgage-backed
securities issued by U.S. Government agencies.

Principal Risks

Corporate Fixed Income Securities Risk - Corporate fixed income securities
respond to economic developments, especially changes in interest rates, as well
as perceptions of the creditworthiness and business prospects of individual
issuers.

Credit Risk - The risk that the issuer of a security or the counterparty to a
contract will default or otherwise become unable to honor a financial
obligation.

Derivatives Risk - The Fund's use of futures contracts, options, forward
contracts and swaps is subject to market risk, leverage risk, correlation risk
and liquidity risk. Leverage risk and liquidity risk are described below. Market
risk is the risk that the market value of an investment may move up and down,
sometimes rapidly and unpredictably. Correlation risk is the risk that changes
in the value of the derivative may not correlate perfectly with the underlying
asset, rate or index. The Fund's use of forward contracts and swaps is also
subject to credit risk and valuation risk. Valuation risk is the risk that the
derivative may be difficult to value and/or valued incorrectly. Credit risk is
described above. Each of these risks could cause the Fund to lose more than the
principal amount invested in a derivative instrument.
  
Extension Risk - The risk that rising interest rates may extend the duration of
a fixed income security, typically reducing the security's value.

Fixed Income Market Risk - The prices of the Fund's fixed income securities
respond to economic developments, particularly interest rate changes, as well as
to perceptions about the creditworthiness of individual issuers, including
governments and their agencies. In the case of foreign securities, price
fluctuations will reflect international economic and political events, as well
as changes in currency valuations relative to the U.S. dollar.

Foreign Issuer Risk - The risk that non-U.S. securities may be subject to
additional risks due to, among other things, political, social and economic
developments abroad, currency movements and different legal, regulatory and tax
environments.

Inflation Protected Securities Risk - The value of inflation protected
securities, including TIPS, will typically fluctuate in response to changes in
"real" interest rates, generally decreasing when real interest rates rise and
increasing when real interest rates fall. Real interest rates represent nominal
(or stated) interest rates reduced by the expected impact of inflation. In
addition, interest payments on inflation-indexed securities will generally vary
up or down along with the rate of inflation.

Interest Rate Risk - The risk that the value of fixed income securities,
including U.S. Government securities, will fall due to rising interest rates.

Leverage Risk - The use of leverage can amplify the effects of market volatility
on the Fund's share price and may also cause the Fund to liquidate portfolio
positions when it would not be advantageous to do so in order to satisfy its
obligations.

Liquidity Risk - The risk that certain securities may be difficult or impossible
to sell at the time and the price that the Fund would like. The Fund may have to
lower the price, sell other securities instead or forego an investment
opportunity, any of which could have a negative effect on Fund management or
performance.

Mortgage-Backed Securities Risk - Mortgage-backed securities are affected by,
among other things, interest rate changes and the possibility of prepayment of
the underlying mortgage loans. Mortgage-backed securities are also subject to
the risk that underlying borrowers will be unable to meet their obligations.

Portfolio Turnover Risk - Due to its investment strategy, the Fund may buy and
sell securities frequently. This may result in higher transaction costs and
additional capital gains tax liabilities.

Prepayment Risk - The risk that, with declining interest rates, fixed income
securities with stated interest rates may have the principal paid earlier than
expected, requiring the Fund to invest the proceeds at generally lower interest
rates.

U.S. Government Securities Risk - Although U.S. Government securities are
considered to be among the safest investments, they are not guaranteed against
price movements due to changing interest rates. Obligations issued by some U.S.
Government agencies are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

Loss of money is a risk of investing in the Fund.

Performance Information

As of January 31, 2012, Class I Shares of the Fund had not commenced operations
and did not have a performance history.

The bar chart and the performance table below provide some indication of the
risks of investing in the Fund by showing changes in the Fund's performance from
year to year for each calendar year since inception and by showing how the
Fund's average annual returns for 1 year, and since the Fund's inception,
compared with those of a broad measure of market performance. Since Class I
Shares are invested in the same portfolio of securities, return for Class I
Shares will be substantially similar to those of Class A Shares, shown here, and
will differ only to the extent that Class I Shares have higher expenses. The
Fund's past performance (before and after taxes) is not necessarily an
indication of how the Fund will perform in the future. For current performance
information, please call 1-800-DIAL-SEI.

[1] Because the Fund incurred AFFE during the most recent fiscal year, the operating expenses in this fee table will not correlate to the expense ratio in the Fund's financial statements (or the "Financial Highlights" section in the prospectus) because the financial statements include only the direct operating expenses incurred by the Fund, not the indirect costs of investing in other investment companies.
