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:

SIMT LARGE CAP VALUE FUND Class I	126	393	681	1,500

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 63%
of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Large Cap Value Fund will invest at least 80% of
its net assets (plus the amount of any borrowings for investment purposes) in
equity securities of large companies, including ETFs and ADRs. For purposes of
this Fund, a large company is a company with a market capitalization in the
range of companies in the Russell 1000 Value Index (between $117 million and
$406 billion as of December 31, 2011) at the time of purchase. The market
capitalization range and the composition of the Russell 1000 Value Index are
subject to change. The Fund may also, to a lesser extent, invest in common and
preferred stocks of small capitalization companies. The Fund may invest up to
20% of its assets in foreign securities.

The Fund uses a multi-manager approach, relying on a number of Sub-Advisers with
differing investment philosophies to manage portions of the Fund's portfolio
under the general supervision of SIMC. In managing its portion of the Fund's
assets, each Sub-Adviser selects stocks it believes are undervalued in light of
such fundamental characteristics as earnings, book value or return on equity.

Principal Risks

Depositary Receipts Risk - Depositary receipts, such as ADRs, are certificates
evidencing ownership of shares of a foreign issuer that are issued by depositary
banks and generally trade on an established market. Depositary receipts are
subject to many of the risks associated with investing directly in foreign
securities, including, among other things, political, social and economic
developments abroad, currency movements and different legal, regulatory and tax
environments.

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.

Foreign Investment 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.

Investment Style Risk - The risk that large capitalization securities 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 seller would like. The seller 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.

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

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

Performance Information

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 the past ten calendar years and by showing how the Fund's
average annual returns for 1, 5 and 10 years, and since the Fund's inception,
compared with those of a broad measure of market performance. 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, call

Best Quarter: 17.15% (06/30/03)
Worst Quarter: -20.73% (12/31/08)

Average Annual Total Returns (for the periods ended December 31, 2011)

The Fund's Class I Shares commenced operations on August 6, 2001. Therefore, the
Fund's average annual total returns for the periods prior to that time are based
on the average annual total returns of the Class A Shares, adjusted for the
higher expenses of the Class I Shares. The Fund's actual inception date is April
20, 1987, but between April 20, 1987 and October 3, 1994, the Fund was advised
by a different investment adviser.

After-tax returns are calculated using the historical highest individual federal
marginal income tax rates and do not reflect the impact of state and local
taxes. Your actual after-tax returns will depend on your tax situation and may
differ from those shown. After-tax returns shown are not relevant to investors
who hold their Fund shares through tax-deferred arrangements, such as 401(k)
plans or individual retirement accounts.

[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.

[1] Index returns are shown from October 31, 1994.
