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 shows the operating expenses you would incur as a shareholder if you invested $10,000 in the Fund over the time periods shown and you redeem all your shares at the end of those periods. The example assumes that the average annual return was 5%, operating expenses remained the same, and expenses were capped for one year in each period.

Although your actual costs may be higher or lower, based on the above assumptions, your costs would be:

Expense Example ASTON/TAMRO DIVERSIFIED EQUITY FUND (USD $)	1 Year	3 Years	5 Years	10 Years
Class N Shares	122	417	734	1,632
Class I Shares	97	339	600	1,348

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 40.41%.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in equity securities. The subadviser seeks opportunities across the growth/value spectrum, resulting in what is generally considered a diversified “core” portfolio. While the Fund invests primarily in equity securities of large-cap companies, the Fund may also have holdings outside of the large capitalization range. The Fund defines a large-cap company as one having a capitalization greater than $6 billion at the time of acquisition.

The subadviser’s investment process focuses on bottom-up stock selection with the goal of identifying companies that possess a sustainable competitive advantage combined with an attractive valuation. A sustainable competitive advantage may be derived from a unique product or service offering, a capable and experienced management team, and financial flexibility in allocating capital.

Through the use of both qualitative and quantitative evaluation, the subadviser seeks securities that it believes meet the specific criteria of one of three investment categories:

• Leaders (historically leading market share and above average profitability),
• Laggards (failed to create value in recent years, but have the potential for significant gains in profitability as new or reinvigorated management seeks to restructure operations), and
• Innovators (commitment to the introduction of new or innovative products or services).

The Fund may invest in real estate investment trusts (“REITs”), foreign securities (directly and through depositary receipts), convertible preferred stocks, and convertible bonds. The Fund may invest in options on securities and securities indices for hedging purposes or to seek capital appreciation. Conversely, the subadviser may sell covered call options on securities held in the portfolio.

To manage risk, the subadviser limits position sizes, diversifies across both market sectors and capitalization, and adheres to a structured sell discipline.

PRINCIPAL RISKS

You could lose money by investing in the Fund. There can be no assurance that the Fund’s investment objective will be achieved. The following is a summary of the principal risks of investing in the Fund.

Convertible Securities Risk. Convertible preferred stocks, which are convertible into shares of the issuer’s common stock and pay regular dividends, and convertible bonds, which are convertible into shares of the issuer’s common stock and bear interest, are subject to the risks of equity securities and fixed income securities. The lower the conversion premium, the more likely the price of the convertible security will follow the price of the underlying common stock. Conversely, higher premium convertible securities are more likely to exhibit the behavior of bonds because the likelihood of conversion is lower, which may cause their prices to fall as interest rates rise.

The value of a convertible security is also affected by the credit quality of the issuer and any call provisions. There is the risk that the issuer of convertible preferred stock will not be able to make dividend payments or that the issuer of a convertible bond will not be able to make principal and/or interest payments.

Derivatives Risk. Risks associated with derivatives may include the risk that the derivative is imperfectly correlated with the security, index or currency to which it relates, the risk that derivatives may not have the intended effects and may result in losses or missed opportunities and the risk that the Fund will be unable to sell or otherwise close out the derivative. Derivative transactions could also expose the Fund to the effects of leverage, which could increase the Fund’s exposure to the market and magnify potential losses. There is no guarantee that derivatives, to the extent employed, will have the intended effect, and their use could cause lower returns or even losses to the Fund. The use of derivatives by the Fund to hedge risk may reduce the opportunity for gain by offsetting the positive effect of favorable price movements. The use of over-the-counter derivatives subjects the Fund to the risk that the counterparty to the derivative may be unwilling or unable to meet its obligations on the investment. The use of certain derivatives may expose the Fund to the underlying market or other reference asset in an amount exceeding the cash investment of the Fund.

Foreign Securities Risk. Investing in the securities of foreign issuers involves special risks and considerations in addition to those typically associated with investing in U.S. companies. The securities of foreign companies may be less liquid and their prices may fluctuate more widely than those traded in U.S. markets. Foreign companies and markets may also have less governmental supervision. There may be difficulty in enforcing contractual obligations against, and little public information about, the companies. Trades typically take more time to settle and clear, and the costs of buying and selling foreign securities are generally higher than the costs associated with buying and selling securities traded in U.S. markets.

The values of the foreign securities held by the Fund may be affected by changes in currency exchange rates or control regulations. If a local currency gains against the U.S. dollar, the value of a holding denominated in that currency increases in U.S. dollar terms. If a local currency declines against the U.S. dollar, the value of the holding decreases in U.S. dollar terms. Changes in economic, tax or foreign investment policies, or other political, governmental or economic actions can adversely affect the value of the foreign securities held by the Fund. In foreign countries, accounting, auditing and financial reporting standards and other regulatory practices and requirements are generally different from those required for U.S. companies. Investments in securities of foreign issuers may also be subject to foreign withholding and other taxes.

Growth Style Risk. Growth investing involves buying stocks of companies that the subadviser believes offer above-average growth potential. These stocks may have relatively high valuations, as measured by traditional valuation metrics (e.g., price-to-earnings ratios or price-to-book ratios). Growth stocks may be more volatile than other stocks because they are generally more sensitive to investor perceptions and market moves. Because different types of stocks go in and out of favor with prevailing market and economic conditions, the Fund’s performance may be adversely affected when growth stocks underperform.

Liquidity Risk. When there is no willing buyer and a security cannot be readily sold at the desired time or price, the Fund may need to accept a lower price or may not be able to sell the security at all. An inability to sell securities, at the Fund’s desired price or at all, can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Less liquid securities are more difficult to dispose of at their recorded values and are subject to wider bid-ask spreads and volatility.

Manager Risk. The performance of the Fund is dependent upon the investment adviser’s skill in selecting managers and the subadviser’s skill in making appropriate investments. As a result, the Fund may underperform its benchmark or its peers.

Market Risk. The Fund’s share price can move down in response to stock market conditions, changes in the economy or changes in a particular company’s stock price. An individual stock may decline in value even when the value of stocks in general is rising.

REIT Risk. Securities of REITs may be affected by changes in the values of their underlying properties. REITs depend generally on their ability to generate cash flow to make distributions to shareholders or unitholders, which may be subject to defaults by borrowers and self-liquidations. Some REITs may have limited diversification and may be subject to risks inherent in investments in a limited number of properties, in a narrow geographic area, or in a single property type. Real estate prices are also affected by general economic conditions. When growth is slowing, demand for property decreases and prices and rents may decline. High or rising interest rates, which result in high or rising mortgage and financing costs, may restrain buying and selling activity, reducing the appeal of real estate investments. Distributions from REITs generally are taxed as ordinary income for federal income tax purposes.

Value Style Risk. Value investing involves buying stocks that the subadviser believes are out of favor and/or undervalued in comparison to their peers or their prospects for growth. Typically, the valuation levels of value stocks are less than those of growth stocks. Because different types of stocks go in and out of favor with prevailing market and economic conditions, the Fund’s performance may be adversely affected when value stocks underperform.

FUND PERFORMANCE

The bar chart shows how the Fund’s performance of Class N shares of the Fund has varied from year to year over the periods shown. Class N shares and Class I shares are invested in the same portfolio of securities, so the annual returns would differ only to the extent that the classes have different expenses. The annual returns of the Class I shares would be higher than the returns of the Class N shares due to 12b-1 fees paid by Class N shares. This information may help illustrate the risks of investing in the Fund. The Fund makes updated performance information available on the Fund’s website, www.astonfunds.com, or by calling toll-free 800-992-8151. As with all mutual funds, past performance (before and after taxes) does not guarantee future performance.
