EXPENSE RATIOS ASSOCIATED WITH THE FUNDS:

RISKS ASSOCIATED WITH THE FUNDS:
Balanced, Retirement Income and Appreciation, High Yield Bond, Intermediate Bond, Short-Term Bond and Treasury Inflation Protected Securities Funds: Investing in debt securities entails interest rate risk, which is the risk that debt securities will decrease in value with increases in market interest rates. Investing in high yield securities involves additional risks when compared to investing in investment-grade securities. These include a greater risk of default or bankruptcy and an increased sensitivity to financial difficulties or changes in interest rates.

Small Cap Value, Mid-Cap Value and Small Cap Index Funds: Investing in the securities of small and mid-capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies.

International Equity, International Equity Index and Emerging Markets Funds: Investing in foreign equities entails additional risk not associated with domestic equities, such as currency fluctuations, economic and political instability, and differences in accounting standards. The risks of investing in foreign equities are heightened when investing in emerging markets.

Zebra Large Cap and Zebra Small Cap Equity Funds: An investment in the Funds is subject to risk, including the possible loss of principal. At times, certain securities may have limited marketability and may be difficult to sell. Investing in the securities of small capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. Newly organized, actively managed Funds have no trading history, and there can be no assurance that active trading markets will be developed or maintained.

SiM High Yield Opportunities Fund: All investing involves risk including the possible loss of principal. The Fund typically invests in a diversified portfolio of domestic and foreign high-yield, high risk fixed income securities that are generally rated below investment-grade (such as BB or lower by Standard & Poor’s Ratings Services or Fitch Ratings and/or Ba or lower by Moody’s Investors Service, Inc.) or deemed to be below investment-grade by the investment sub-advisor. These types of securities are commonly referred to as “high yield” or “junk” bonds. Investing in such securities involves additional risks when compared to investing in investment-grade securities. These include a greater risk of default or bankruptcy and an increased sensitivity to financial difficulties or changes in interest rates. The principal risks of the Fund include those derived from the investment in: foreign securities, emerging market securities, derivative securities including options and futures contracts (including options and futures contracts on stock indices and currencies), forward contracts (including currency forward contracts), swap agreements and structured notes, Rule 144A securities, bank loans and senior loans and to a lesser extent equity securities including those of small and mid-capitalization companies. Please see the prospectus for a more complete discussion of the risks of investing in this Fund.

Flexible Bond Fund: Because the Fund has a flexible approach to investing, the risks of the Fund are likewise varied. The primary risks fall into one of several broad categories including high yield securities risk, credit risk, foreign investment risk, derivatives risk, interest rate risk and non-diversification risk. Investing in foreign denominated and/or domiciled securities may involve heightened risk due to currency fluctuations, economic risks and political risks, which may be enhanced in emerging markets. Mortgage and asset-backed securities may be sensitive to changes in interest rates, subject to early repayment risk, and their value may fluctuate in response to the market’s perception of issuer creditworthiness; while generally supported by some form of government or private guarantee, there is no assurance that private guarantors will meet their obligations. Income from municipal bonds may be subject to state and local taxes and at times the alternative minimum tax. Derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when most advantageous. Investing in derivatives could result in losing more than the amount invested. Diversification does not ensure against loss. Investing in debt securities entails interest rate risk that debt securities will decrease in value with increases in market interest rates. Bonds and bond funds with longer durations tend to be more sensitive and more volatile than securities with shorter durations; bond prices generally fall as interest rates rise. Please see the prospectus for a complete discussion of the Fund’s risks.
