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) Opportunistic Equity Fund Service Class	165	515	890	1,942

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 78.58% 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’s investments in equity securities may include common stocks and preferred stocks of companies of any size capitalization.  Common stock is an equity security that represents a proportionate share of the ownership of a company; its value is based on the success of the company’s business, any income paid to stockholders, the value of its assets and general market conditions.  Preferred stock is generally senior to common stock, but subordinate to debt securities, with respect to the payment of dividends and on liquidation of the issuer.  The market value of preferred stock is generally subject to decreases when interest rates rise and is also affected by the issuer’s ability to make payments on the preferred stock.

One of the Fund’s sub-advisors, Westfield Capital Management Company, L.P. (“Westfield”), utilizes all-cap growth investment strategies.  The other two sub-advisors, Diamond Hill Capital Management, Inc. (“Diamond Hill”) and River Road Asset Management, LLC (“River Road”), utilize all-cap value investment strategies.  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 a concentrated portfolio within its allocated portion of the Fund’s assets.  The Fund is designed to provide the sub-advisors with significant flexibility to pursue attractive equity investment opportunities across all sectors and capitalization ranges.

While the sub-advisors will primarily invest in U.S. markets, they may opportunistically invest internationally.  The Fund may invest up to 35% of its total assets in American Depositary Receipts (“ADRs”) and securities of foreign companies in both developed or emerging market countries.  ADRs are typically issued by a U.S. 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) seek to manage portfolio volatility.   The types of derivatives in which the Fund may invest include futures, forwards, options and swaps.

Each sub-advisor may maintain a significant cash position within its allocated portion of the Fund’s portfolio at times when the sub-advisor does not perceive an adequate number of attractive 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 your money on your investment in the Fund.  The following risks could affect the value of your investment:

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 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 a contract with a value based on the performance of an underlying financial asset, index or other measure.  The use of derivative contracts may involve 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.

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.

Non-Diversification Risk: The Fund is a non-diversified investment company, which means that more of its assets may be invested in the securities of a single issuer than a diversified investment company.  As a non-diversified fund, the Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

Portfolio Turnover Risk:  Depending on market and other conditions, the Fund may experience high portfolio turnover, which may result in higher brokerage commissions and transactions costs, as well as higher taxes.

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.
