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:

PORTFOLIO TURNOVER

The Fund will pay 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.

Principal Investment Strategies

Under normal circumstances, the Global Equity Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities. The Fund also may invest in futures contracts, foreign currency forward contracts, swaps and options, either for hedging and risk management purposes, including to seek to manage the Fund’s currency exposure to foreign securities and mitigate the Fund’s overall risk, or as part of its investment strategies.

The Fund will invest primarily in common stocks and other equity securities of issuers located in developed market countries, including the U.S. Under normal circumstances, the Fund will invest in at least four countries outside of the U.S., but will typically invest much more broadly. At least 30% of the Fund’s assets will be invested in non-U.S. issuers at any time and it is generally expected that approximately 50% of the Fund’s assets will be invested in non-U.S. issuers consistent with the Fund’s benchmark. However, the Fund’s investments in non-U.S. issuers will vary depending on market conditions and implementation of the Fund’s investment strategy at a particular point in time.

The Fund may also invest, to a limited extent, in securities of issuers located in emerging market countries. The Fund will not invest more than 15% of its assets in the common stock or other equity securities of issuers located in emerging market countries. Emerging market countries are countries that the World Bank classifies as low, low-middle and upper-middle income countries.

The Fund uses a multi-manager approach, relying upon a number of Sub-Advisers with differing investment philosophies to manage portions of the Fund’s portfolio under the general supervision of SIMC. The Fund is diversified as to issuers, market capitalization, industry and country. The Fund may also invest in ETFs to gain exposure to a particular portion of the market while awaiting an opportunity to purchase securities directly.

Principal Risks

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, forward contracts, options and swaps is subject to market risk, leverage risk, correlation risk and liquidity risk. Leverage risk, liquidity risk and market risk are described below. Many over-the-counter (“OTC”) derivative instruments will not have liquidity beyond the counterparty to the instrument. 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 swap agreements is also subject to credit risk and valuation risk. Valuation risk is the risk that the derivative may be difficult to value and/or may be 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. If a counterparty’s creditworthiness declines, the value of a swap agreement with that counterparty would be likely to decline, potentially resulting in losses. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment.  The other parties to certain derivative contracts present the same types of credit risk as issuers of fixed income securities.  The Fund’s use of derivatives may also increase the amount of taxes payable by shareholders.  Recent legislation calls for new regulation of the derivatives markets.  The extent and impact of the regulation are not yet fully known and may not be for some time.  New regulation of derivatives may make them more costly, may limit their availability or may otherwise adversely affect their value or performance.  Derivatives are also subject to a number of other risks described elsewhere in this prospectus.  Derivatives transactions conducted outside the U.S. may not be conducted in the same manner as those entered into on U.S. exchanges, and may be subject to different margin, exercise, settlement or expiration procedures.  Derivatives transactions conducted outside the U.S. also are subject to the risks affecting foreign securities, currencies and other instruments, in addition to other 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. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses.

Foreign Investment/Emerging Markets 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. These additional risks may be heightened with respect to emerging market countries since political turmoil and rapid changes in economic conditions are more likely to occur in these countries.

Investment Style Risk — The risk that investments in securities pursuant to a global strategy may underperform other segments of the equity markets or the equity markets as a whole.

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.

Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the bond market as a whole.

Small and Medium Capitalization Risk — The risk that small and medium 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 and medium capitalization companies may have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over the counter or listed on an exchange.

Investing in the Fund involves risk, and there is no guarantee that the Fund will achieve its investment goal. You could lose money on your investment in the Fund, just as you could with other investments.
