Example

The following Example is intended to help you compare the cost of investing in Service Shares of the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in Service Shares of 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:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
Service Class Prospectus GuideMark(SM) Tax-Exempt Fixed Income Fund Service Shares	131	424	738	1,629

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 30.36% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Under normal circumstances, the Fund invests at least 80% of its assets in municipal fixed income securities, the interest on which is generally exempt from federal income tax and not subject to the alternative minimum tax (“AMT”).

The Fund primarily invests its assets in municipal securities that are investment grade (i.e., rated within one of the four highest rating categories by a Nationally Recognized Statistical Rating Organization (“NRSRO”) or determined to be of comparable quality by the Fund’s sub-advisor if the security is unrated).  The Fund may, to a lesser extent, invest in lower-rated municipal securities.

Municipal securities are debt obligations issued by or on behalf of the cities, districts, states, territories and other possessions of the United States that pay income exempt from regular federal income tax.

The Fund has the ability to invest in all maturities, but will generally invest in intermediate- to long-term municipal securities.  Intermediate-term municipal securities are those securities that generally mature within three to ten years.  Long-term municipal securities generally mature some time after ten years.  The average dollar-weighted portfolio maturity of the portfolio is expected to be maintained between three and fifteen years.  Some of the securities in the Fund’s portfolio may carry credit enhancements, such as insurance, guarantees or letters of credit.

The Fund’s portfolio is constructed by combining the investment styles and strategies of multiple sub-advisors.  Each sub-advisor uses its own proprietary research and securities selection processes to manage its allocated portion of the Fund’s assets.  The Fund is designed to allow the sub-advisors to invest in the broad municipal securities market while seeking to maintain the Fund’s duration within a relatively close range to the duration of the Fund’s benchmark index.  Duration is a measure of the sensitivity of the price of a debt security (or a portfolio of debt securities) to changes in interest rates.  The prices of debt securities with shorter durations generally will be less affected by changes in interest rates than the prices of debt securities with longer durations.

Principal Risks of Investing in the Fund

The risks associated with an investment in the Fund can increase during times of significant market volatility.  There is the risk that you could lose all or a portion of the money you have invested in the Fund.  The following risks could affect the value of your investment in the Fund:

Municipal Securities Risk:  The Fund is subject to municipal securities risks.  The ability of the Fund to achieve its investment objective depends on the ability of the issuers of the municipal securities, or any entity providing a credit enhancement, to continue to meet their obligations for the payment of interest and principal when due.  Any adverse economic conditions or developments affecting the states or municipalities that issue the municipal securities in which the Fund invests could negatively impact the Fund.

Management Risk:  An investment or allocation strategy used by the Advisor or a sub-advisor may fail to produce the intended results.

Market Risk:  The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity and fixed income markets as well as the financial condition and prospects of issuers in which the Fund invests.

Interest Rate Risk:  The market value of fixed income securities will fluctuate with changes in interest rates.  For example, when interest rates rise, the market value of fixed income securities declines.  If the market value of the  Fund’s investments decreases, investors in the Fund may lose money.

High-Yield Debt Securities Risk:  High-yield debt securities or “junk bonds” are debt securities rated below investment grade by an NRSRO.  Junk bonds are subject to greater credit risk than higher-grade securities and have a greater risk of default.  Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.  In addition, the purchase of debt securities which have previously fallen from investment grade to sub-investment grade status – and in particular the purchase of such instruments that have already been declared in default as to either income or principal – is particularly speculative and may lead to a loss of Fund value.

Credit Risk:  Individual issues of fixed income securities may be subject to the credit risk of the issuer.  This means that the issuer of a fixed income security, or in the case of a municipal security, the underlying municipality, may experience financial problems, causing it to be unable to meet its payment obligations.

Tax Risk:  Because interest income on municipal obligations is normally not subject to regular federal income taxation, the attractiveness of municipal obligations in relation to other investment alternatives is affected by changes in federal income tax rates applicable to, or the continuing tax-exempt status of, such interest income.  Some income may be subject to the federal alternative minimum tax (“AMT”) that applies to certain investors.

Maturity Risk:  The Fund generally invests in municipal securities with intermediate- to long-term maturities.  Generally, the longer a security’s maturity, the greater the risk that interest rate fluctuations may adversely affect the value of the security.

Liquidity Risk:  Liquidity risk is the risk that certain securities may be difficult or impossible to buy or sell at the time and price that the Fund would like to buy or sell the security.
