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 redeem all of your shares at the end of those periods (except where indicated). The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the example is based on the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and on the Total Annual Fund Operating Expenses for the remaining years. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class C	298	732	1,293	2,822
Class Y	97	426	779	1,774

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 for you if your 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 period from March 30, 2012 (the Fund’s inception date) through November 30, 2012, the Fund’s portfolio turnover rate was 14% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 70% of its assets in equity securities (the “equity portion”). Equity securities purchased by the Fund may include common stocks, preferred stocks and convertible securities, including, among others, warrants, convertible debt securities and convertible preferred stock. A significant majority of the equity securities purchased by the Fund will be traded on a U.S. exchange and denominated in U.S. dollars. The Fund’s non-U.S. equity investments, which will consist generally of American Depositary Receipts but may include direct foreign investments as well, will be limited to 10% of the equity portion. Although certain of the equity securities purchased by the Fund may be issued by domestic companies incorporated outside of the United States, the Adviser does not consider these securities to be foreign if they are included in U.S. equity indices published by Standard & Poor’s or Russell Investments. The Fund expects that under normal market conditions a part of the equity portion will include income-producing equity securities.

The Fund may invest up to 30% of its assets in fixed-income securities, including below investment-grade fixed-income securities (commonly known as “junk bonds”), corporate debt and government and agency fixed-income securities (the “fixed-income portion”). Below investment-grade fixed-income securities are rated below investment grade quality, i.e. , none of the three major ratings agencies (Moody’s Investors Services, Inc., Fitch Investor Services, Inc. or Standard & Poor’s Ratings Group) have rated the securities in one of their respective top four ratings categories, or, in the absence of a rating by an agency, the Adviser has determined that the securities are of comparable quality to rated securities that the Fund may purchase. Up to 40% of the fixed-income portion of the Fund may be non-U.S. dollar denominated and up to 20% of the fixed-income portion of the Fund may be invested in a single country or currency; however, these restrictions do not apply to investments in Canadian or U.S. fixed-income securities. The Fund may invest in securities of any maturity, market capitalization and credit quality.

The Adviser may shift the Fund’s assets among various types of income-producing securities based upon changing market conditions and security-specific opportunities. The asset allocation shifts will be based on several criteria, such as the attractiveness of each asset class as determined by the Adviser, the security-specific valuations and yield opportunities discovered within each asset class and the ability of an asset class to provide diversification and attractive risk characteristics to the portfolio. When assessing the investment opportunity of a particular company, the Adviser has the flexibility to consider the entire range of securities across the company’s capital structure, including equities, preferred stock, convertible bonds and bonds. The Adviser will strive for a reasonable amount of income through bond yields, stock dividends and other income-enhancing strategies.

In deciding which equity securities to buy and sell, the Adviser seeks to identify companies that it believes are, among other things, attractively valued based on the Adviser’s estimate of intrinsic value, with additional consideration given to dividend yield. The Adviser generally seeks to find value by selecting individual stocks that it believes are attractive, rather than by attempting to achieve investment growth by rotating the Fund’s holdings among various sectors of the economy.

In deciding which fixed income securities to buy and sell, the Adviser may consider a number of factors related to the bond issue and the current bond market, for example, the stability and volatility of a country’s bond markets, the financial strength of the issuer, current interest rates, the Adviser’s expectations regarding general trends in interest rates and currency considerations. The Adviser will also consider how purchasing or selling a bond would impact the overall portfolio’s risk profile (for example, its sensitivity to currency risk, interest rate risk and sector-specific risk) and potential return (income and capital gains).

The Fund may also invest in securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Rule 144A securities”) and may purchase and sell (write) options for hedging and investment purposes. Except as provided above, the Fund is not limited in the percentage of its assets that it may invest in these instruments.

Principal Risks

The principal risks of investing in the Fund are summarized below. The Fund does not represent a complete investment program. You may lose money by investing in the Fund.

Allocation Risk: The Fund’s investment performance depends on how its assets are allocated. The allocation, as set forth above, may not be optimal in every market condition. You could lose money on your investment in the Fund as a result of this allocation.

Below Investment-Grade Fixed-Income Securities Risk: The Fund’s investments in below investment-grade fixed-income securities, also known as “junk bonds,” may be subject to greater risks than other fixed-income securities, including being subject to greater levels of interest rate risk, credit risk (including a greater risk of default) and liquidity risk. The ability of the issuer to make principal and interest payments is predominantly speculative for below investment-grade fixed-income securities.

Credit Risk: Credit risk is the risk that the issuer or the guarantor of a fixed-income security, or the counterparty to a derivatives or other transaction, will be unable or unwilling to make timely payments of interest or principal or to otherwise honor its obligations.

Currency Risk: Fluctuations in the exchange rates between different currencies may negatively affect an investment. The Fund may elect not to hedge currency risk, or may hedge such risk imperfectly, which may cause the Fund to incur losses that would not have been incurred had the risk been hedged.

Equity Securities Risk: The value of the Fund’s investments in equity securities could be subject to unpredictable declines in the value of individual securities and periods of below-average performance in individual securities or in the equity market as a whole. Value stocks can perform differently from the market as a whole and from other types of stocks. Value stocks also present the risk that their lower valuations fairly reflect their business prospects and that investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds generally take precedence over the claims of those who own preferred stock or common stock.

Fixed-Income Securities Risk: Fixed-income securities are subject to credit risk, interest rate risk and liquidity risk. You may lose money on your investment due to unpredictable drops in a security’s value or periods of below-average performance in a given security or in the securities market as a whole. In addition, an economic downturn or period of rising interest rates could adversely affect the market of these securities and reduce the Fund’s ability to sell them. Below investment-grade fixed-income securities may be subject to these risks (including the risk of default) to a greater extent than other fixed-income securities.

Foreign Securities Risk: Investments in foreign securities may be subject to greater political, economic, environmental, credit and information risks. The Fund’s investments in foreign securities are also subject to foreign currency fluctuations. Foreign securities may be subject to higher volatility than U.S. securities, varying degrees of regulation and limited liquidity.

Interest Rate Risk: Changes in interest rates may cause the value of the Fund’s investments to decrease. Generally, the value of fixed-income securities rises when prevailing interest rates fall and falls when interest rates rise. A prolonged period of low interest rates may cause the Fund to have a low or negative yield, potentially reducing the value of your investment.

Issuer Risk: The value of the Fund’s investments may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.

Large Investor Risk: Ownership of shares of the Fund may be concentrated in one or a few large investors. Such investors may redeem shares in large quantities or on a frequent basis. Redemptions by a large investor can affect the performance of the Fund, may increase realized capital gains, may accelerate the realization of taxable income to shareholders and may increase transaction costs. These transactions potentially limit the use of any capital loss carryforwards and certain other losses to offset future realized capital gains (if any). Such transactions may also increase the Fund’s expenses.

Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell, possibly preventing the Fund from selling these illiquid securities at an advantageous price or time. A lack of liquidity also may cause the value of investments to decline. Securities acquired in a private placement, such as Rule 144A securities, generally are subject to strict restrictions on resale and there may be no liquid secondary market or ready purchaser for such securities. Therefore, the Fund may be unable to dispose of such securities when it desires to do so, or at the most advantageous time or price. Illiquid investments also may be difficult to value.

Management Risk: A strategy used by the Fund’s portfolio managers may fail to produce the intended result.

Market Risk: The market value of a security will move up and down, sometimes rapidly and unpredictably, based upon a change in an issuer’s financial condition, as well as overall market and economic conditions.

Options Risk: The value of the Fund’s positions in options will fluctuate in response to changes in the value of the underlying security. Writing call options can reduce the risk of owning stocks, but it limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash at the time of selling the call option. When the Fund writes a put option, it assumes the risk that it may be required to purchase the underlying security for a price that is higher than prevailing market price, resulting in a loss. The Fund also risks losing all or part of the cash paid for purchasing put options. Unusual market conditions or the lack of a ready market for any particular option at a specific time may reduce the effectiveness of the Fund’s option strategies, and for these and other reasons the Fund’s use of options may not achieve the Fund’s investment objectives to the extent desired.

Valuation Risk: This is the risk that the Fund has valued certain securities at a higher price than the price at which they can be sold. This risk may be especially pronounced for investments, such as derivatives, that may be illiquid or may become illiquid.
