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:

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 119%

of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the International Fixed Income Fund will invest at

least 80% of its net assets (plus the amount of any borrowings for investment

purposes) in fixed income securities. The Fund will invest primarily in

investment grade foreign government and corporate fixed income securities, as

well as foreign mortgage-backed and/or asset-backed fixed income securities, of

issuers located in at least three countries other than the U.S. It is expected

that at least 40% of the Fund's assets will be invested in non-U.S. securities.

Other fixed income securities in which the Fund may invest include: (i)

securities issued or guaranteed by the U.S. Government and its agencies and

instrumentalities and obligations of U.S. commercial banks, such as certificates

of deposit, time deposits, bankers' acceptances and bank notes; and (ii) U.S.

corporate debt securities and mortgage-backed and asset-backed securities. 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. In selecting investments for the Fund,

the Sub-Advisers choose investment grade securities issued by corporations and

governments located in various developed foreign countries, looking for

opportunities to achieve capital appreciation and gain, as well as current

income. There are no restrictions on the Fund's average portfolio maturity or on

the maturity of any specific security.



The Sub-Advisers may seek to enhance the Fund's return by actively managing the

Fund's foreign currency exposure. In managing the Fund's currency exposure, the

Sub-Advisers buy and sell currencies (i.e., take long or short positions) using

futures and foreign currency forward contracts. The Fund may take long and short

positions in foreign currencies in excess of the value of the Fund's assets

denominated in a particular currency or when the Fund does not own assets

denominated in that currency. The Fund may also engage in currency transactions

in an attempt to take advantage of certain inefficiencies in the currency

exchange market, to increase its exposure to a foreign currency or to shift

exposure to foreign currency fluctuations from one currency to another. In

managing the Fund's currency exposure for foreign securities, the Sub-Advisers

may buy and sell currencies for hedging or for speculative purposes.



The Fund may also invest in futures contracts, forward contracts and swaps for

speculative or hedging purposes. Futures, forwards and swaps are used to

synthetically obtain exposure to the securities identified above or baskets of

such 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, currencies or

market segments. Interest rate swaps are further used to manage the Fund's yield

spread sensitivity. When the Fund seeks to take an active long or short position

with respect to the likelihood of an event of default of a security or basket of

securities, the Fund may use credit default swaps. The Fund may buy credit

default swaps in an attempt to manage credit risk where the Fund has credit

exposure to an issuer and the Fund may sell credit default swaps to more

efficiently gain credit exposure to such security or basket of securities.



The Fund will also invest in securities rated below investment grade (junk

bonds). However, in general, the Fund will purchase bonds with a rating of CCC

or above. The Fund also invests a portion of its assets in bank loans, which are

generally non-investment grade floating rate instruments. The Fund may invest in

bank loans in the form of participations in the loans (participations) and

assignments of all or a portion of the loans from third parties (assignments).



The Fund may purchase shares of ETFs to gain exposure to a particular portion of

the market while awaiting an opportunity to purchase securities directly.

Principal Risks

Asset-Backed Securities Risk -- Payment of principal and interest on asset-backed

securities is dependent largely on the cash flows generated by the assets

backing the securities, and asset-backed securities may not have the benefit of

any security interest in the related assets.



Bank Loans Risk -- With respect to bank loans, the Fund will assume the credit

risk of both the borrower and the lender that is selling the participation. The

Fund may also have difficulty disposing of bank loans because, in certain cases,

the market for such instruments is not highly liquid.



Below Investment Grade Securities Risk -- Fixed income securities rated below

investment grade (junk bonds) involve greater risks of default or downgrade and

are more volatile than investment grade securities because the prospect for

repayment of principal and interest of many of these securities is speculative.



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.



Currency Risk -- As a result of the Fund's investments in securities or other

investments denominated in, and/or receiving revenues in, foreign currencies and

the Fund's active management of its currency exposures, the Fund will be subject

to currency risk. Currency risk is the risk that foreign currencies will decline

in value relative to the U.S. dollar or, in the case of hedging positions, that

the U.S. dollar will decline in value relative to the currency hedged. In either

event, the dollar value of an investment in the Fund would be adversely

affected. Due to the Fund's active positions in currencies, it will be subject

to the risk that currency exchange rates may fluctuate in response to, among

other things, changes in interest rates, intervention (or failure to intervene)

by U.S. or foreign governments, central banks or supranational entities, or by

the imposition of currency controls or other political developments in the

United States or abroad.



Derivatives Risk -- The Fund's use of swaps, futures and forward contracts 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 swaps and over-the-counter forward contracts 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 the above risks could cause the Fund to lose more than

the principal amount invested in a derivative instrument.



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.



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 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.



Interest Rate Risk -- The risk that the Fund's yield will decline due to falling

interest rates. A rise in interest rates typically causes a fall in the value of

fixed income securities in which the Fund invests, while a fall in interest

rates typically causes a rise in the value of such securities.



Investment Style Risk -- The risk that developed international fixed income

securities may underperform other segments of the fixed income markets or the

fixed income 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.



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.



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.



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.



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