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 and returns 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 ESTATE FUND Class A	131	409	708	1,556

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 83%
of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Real Estate Fund will invest at least 80% of its
net assets (plus the amount of any borrowings for investment purposes) in equity
securities of real estate companies (e.g., common stocks, rights, warrants,
ETFs, convertible securities and preferred stocks of REITs and real estate
operating companies (REOCs)). The Fund is non-diversified and expects to hold a
relatively small number of securities, thus increasing the importance of each
holding. Generally, the Fund will invest in real estate companies operating in
the United States. The Fund uses a multi-manager approach, relying upon a number
of Sub-Advisers to manage portions of the Fund's portfolio under the general
supervision of SIMC.

Principal Risks

Equity Market Risk - The risk that stock prices will fall over short or extended
periods of time.

Exchange-Traded Funds (ETFs) Risk - The risks of owning shares of an ETF
generally reflect the risks of owning the underlying securities the ETF is
designed to track, although lack of liquidity in an ETF could result in its
value being more volatile than the underlying portfolio securities.

Investment Style Risk - The risk that the securities of issuers in the real
estate industry may underperform other segments of the equity markets or the
equity markets as a whole.

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.

Non-Diversified Risk - The Fund is non-diversified, which means that it may
invest in the securities of relatively few issuers. As a result, the Fund may be
more susceptible to a single adverse economic or political occurrence affecting
one or more of these issuers and may experience increased volatility due to its
investments in those securities.

Real Estate Industry Risk - Securities of companies principally engaged in the
real estate industry may be subject to the risks associated with the direct
ownership of real estate. Risks commonly associated with the direct ownership of
real estate include fluctuations in the value of underlying properties, defaults
by borrowers or tenants, changes in interest rates and risks related to general
or local economic conditions. The Fund's investments are concentrated in issuers
conducting business in the real estate industry, and therefore the Fund is
subject to legislative or regulatory changes, adverse market conditions and/or
increased competition affecting that industry.

REITs Risk - REITs are trusts that invest primarily in commercial real estate or
real estate-related loans. The Fund's investments in REITs will be subject to
the risks associated with the direct ownership of real estate, which are
discussed above. Some REITs may have limited diversification and may be subject
to risks inherent in financing a limited number of properties.

Small and Medium Capitalization Companies Risk - The smaller and medium
capitalization REITs and other companies in which the Fund invests may be more
vulnerable to adverse business or economic events than larger, more established
companies. In particular, small and medium capitalization companies may have
limited product lines, markets and financial resources and may depend upon a
relatively small management group. Therefore, small and medium capitalization
stocks may be more volatile than those of larger companies. Small and medium
capitalization stocks may be traded over-the-counter or listed on an exchange.

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

[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.
