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) World ex-US Fund Service Shares	163	520	901	1,970

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 75.34% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities.  The Fund will invest primarily in equity securities incorporated or traded outside the United States.  Generally, the Fund’s assets will be invested in securities of companies located in developed and emerging market countries, with regional exposures generally being neutral relative to the Fund’s benchmark.  The Fund will, under normal circumstances, invest in a minimum of three countries outside of the United States.

The Fund’s investments in equity securities may include common stocks, real estate investment trusts (“REITs”), unit stocks, stapled securities, exchange-traded funds (“ETFs”) and preferred stocks of companies of any size capitalization.  The Fund also may invest in depositary receipts, including American Depositary Receipts (“ADRs”) of foreign companies and Global Depositary Receipts (“GDRs”).  Depositary receipts are typically issued by a U.S. or foreign bank or trust company and evidence ownership of underlying securities issued by a foreign corporation.

The Fund also may invest in certain types of derivative instruments in order to (i) “equitize” cash balances by gaining exposure to relevant equity markets; and (ii) hedge exposure to foreign currencies.  The types of derivatives in which the Fund may invest include futures, forward and other similar instruments.  The Fund may engage in currency futures and currency forwards for the purpose of hedging exposures within the Fund to non-dollar-denominated assets.  In general, the use of currency derivatives for hedging may reduce the overall risk level of the Fund, albeit at a cost that may lower overall performance.

The sub-advisor manages the Fund using an optimized strategy that focuses on specialization across the equity markets. The sub-advisor generally seeks to control sector and country exposures relative to the weight of each sector and country in the Fund’s benchmark index and maintain regional neutrality. Within each sector, the sub-advisor uses a fundamental, bottom-up research approach to identify companies that the sub-advisor believes present the greatest investment opportunities.

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:

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 companies in which the Fund invests.

Small and Medium Capitalization Company Risk:  Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies.  As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund’s assets.

Foreign Securities Risk:  The risks of investing in ADRs, GDRs and foreign securities can increase the potential for losses in the Fund and may include currency fluctuations, political and economic instability, less government regulation, less publicly available information, limited trading markets, differences in financial reporting standards, fewer protections for passive investors and less stringent regulation of securities markets.

Emerging Markets Risk:  In addition to the risks generally associated with investing in foreign securities described above, countries with emerging markets may also have relatively unstable governments, fewer shareholder protections, and more limited economies and securities markets.

Derivatives Risk:  A derivative is an instrument with a value based on the performance of an underlying financial asset, index or other measure.  The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments.  Derivatives may be volatile, difficult to value, and the Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price.  In addition, the use of currency derivatives may not match or fully offset changes in the value of the underlying non-dollar-denominated or bank assets.

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 a Fund would like to buy or sell the security.

Real Estate Risk:  The value of real estate-linked derivative instruments and other real estate-related securities may be affected by risks similar to those associated with direct ownership of real estate, in addition to the risks of poor performance by a REIT’s manager, changes to tax laws, and failure by the REIT to qualify for favorable treatment.  REITs may have limited diversification and may not exhibit the same (or any) correlation with inflation that real estate or other real estate securities exhibit.

Exchange-Traded Funds Risk:  An ETF may represent a portfolio of securities, or may use derivatives in pursuit of its stated objective.  The risks of owning an ETF generally reflect the risks of owning the underlying securities held by the ETF, although a lack of liquidity in an ETF could result in it being more volatile.  ETFs have management fees and other expenses which the Fund will indirectly bear.

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.  Actual after-tax returns depend on your tax situation and may differ from those shown.  In addition, the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans and individual retirement accounts because such accounts are only subject to taxes upon withdrawal.  In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Fund Shares” may be higher than the other return figures for the same period.  A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.
