Shareholder Fees (fees paid directly from your investment) 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 you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The portfolio seeks to outperform the MSCI EAFE Index. The MSCI EAFE Index is designed to measure the performance of equities in developed markets outside North America, which include Europe, Australasia (Australia and New Zealand) and the Far East. The portfolio generally will (i) purchase securities, either directly or through derivatives, in an amount up to approximately 130% of its net assets and (ii) sell securities short (which means, sell borrowed securities with the intention of repurchasing them for a profit on the expectation that the market price will drop), either directly or through derivatives, in an amount up to approximately 30% of its net assets. The portfolio may invest in equity securities without regard to market capitalization. The portfolio uses proprietary quantitative models designed to: o forecast the expected relative return of stocks by analyzing a number of fundamental factors, including a company's relative valuation, use of capital, management's approach to financial reporting, profitability, realized and expected growth potential and level and trend of earnings and share price o identify stocks that are likely to suffer declines in price if market conditions deteriorate and either limit the portfolio's overall long exposure or increase the portfolio's overall short exposure to such low quality stocks and o help determine the portfolio's relative exposure to different industry sectors by analyzing sector performance under different market scenarios The portfolio maintains investment attributes that are similar to those of the basket of securities included in the MSCI EAFE Index and intends to limit its divergence from the that index in terms of market, industry and sector exposures.

Simply defined, risk is the possibility that you will lose money or not make money. Principal risk factors for the portfolio are discussed below. Before you invest, please make sure you understand the risks that apply to the portfolio. As with any mutual fund, you could lose money over any period of time. Investments in the portfolio are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. ACTIVE TRADING RISK Active and frequent trading increases transaction costs, which could detract from the portfolio's performance. DERIVATIVES RISK Derivatives, such as options, forwards, futures and swap agreements, are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. The portfolio typically uses derivatives as a substitute for taking a position in the underlying asset and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or currency risks. The portfolio may also use derivatives for leverage. The portfolio's use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives are subject to correlation risk, liquidity risk, interest rate risk, market risk and credit risk. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that the portfolio will engage in these transactions to reduce exposure to other risks when that would be beneficial. FOREIGN SECURITIES RISK A portfolio that invests outside the United States carries additional risks that include: o Currency Risk Fluctuations in exchange rates between the U.S. dollar and foreign currencies may negatively affect an investment. Adverse changes in exchange rates may erode or reverse any gains produced by foreign currency-denominated investments and may widen any losses. Although the portfolio may seek to reduce currency risk by hedging part or all of its exposure to various foreign currencies, it is not required to do so. o Information Risk Key information about an issuer, security or market may be inaccurate or unavailable. o Political Risk Foreign governments may expropriate assets, impose capital or currency controls, impose punitive taxes, or nationalize a company or industry. Any of these actions could have a severe effect on security prices and impair the portfolio's ability to bring its capital or income back to the United States. Other political risks include economic policy changes, social and political instability, military action and war. LEVERAGING RISK When the portfolio uses leverage through activities such as borrowing, entering into short sales, purchasing securities on margin or on a "when-issued" basis or purchasing derivative instruments in an effort to increase its returns, the portfolio has the risk of magnified capital losses that occur when losses affect an asset base, enlarged by borrowings or the creation of liabilities, that exceeds the net assets of the portfolio. The net asset value of the portfolio when employing leverage will be more volatile and sensitive to market movements. Leverage may involve the creation of a liability that requires the portfolio to pay interest. MARKET RISK The market value of a security may fluctuate, sometimes rapidly and unpredictably. These fluctuations, which are often referred to as "volatility," may cause a security to be worth less than it was worth at an earlier time. Market risk may affect a single issuer, industry, sector of the economy, or the market as a whole. Market risk is common to most investments - including stocks and bonds, and the mutual funds that invest in them. MODEL RISK The portfolio bears the risk that the proprietary quantitative models used by the portfolio managers will not be successful in identifying securities that will help the portfolio achieve its investment objective, causing the portfolio to underperform its benchmark or other funds with a similar investment objective. SHORT SALES RISK Short sales expose the portfolio to the risk that it will be required to cover its short position at a time when the securities have appreciated in value, thus resulting in a loss to the portfolio. The portfolio's loss on a short sale could theoretically be unlimited in a case where the portfolio is unable, for whatever reason, to close out its short position. Short sales also involve transaction and other costs that will reduce potential gains and increase potential portfolio losses. The use by the portfolio of short sales in combination with long positions in its portfolio in an attempt to improve performance may not be successful and may result in greater losses or lower positive returns than if the portfolio held only long positions. It is possible that the portfolio's long equity positions will decline in value at the same time that the value of the securities it has sold short increases, thereby increasing potential losses to the portfolio. In addition, the portfolio's short selling strategies may limit its ability to fully benefit from increases in the equity markets. Short selling also involves a form of financial leverage that may exaggerate any losses realized by the portfolio. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the portfolio. CFTC REGULATORY RISK Regulatory changes could adversely affect the portfolio by limiting its trading activities in futures and increasing Fund expenses. On February 11, 2011, the Commodity Futures Trading Commission ("CFTC") published a rule proposal that would limit the Fund's ability to use futures in reliance on certain CFTC exemptions. If the new rule is adopted as proposed, the amended CFTC exemption would limit the portfolio's use of futures to (i) bona fide hedging transactions, as defined by the CFTC, and (ii) speculative transactions, provided that the speculative positions do not exceed 5% of the liquidation value of the portfolio. If the portfolio could not satisfy the requirements for the amended exemption, the disclosure and operations of the portfolio would need to comply with all applicable regulations governing commodity pools. Other potentially adverse regulatory initiatives could develop.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
