You can find the Fund’s prospectus and other information about the Fund online at www.astonfunds.com/FormsProspectuses/Prospectuses. You can also get this information at no cost by calling 800-992-8151 or by sending an e-mail to contactfunds@astonasset.com. The Fund’s prospectus and statement of additional information, each dated March 1, 2011, are incorporated by reference to this summary prospectus.

The Fund seeks long-term capital appreciation and, secondarily, current income, by investing primarily in common stocks and convertible securities.

The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

(expenses that you pay each year as a percentage of the value of your investment)

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% and that operating expenses remained the same.

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

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 57.39%.

The Fund invests primarily in common stocks and convertible securities. The portfolio manager uses a bottom-up approach to stock selection and seeks high quality, well-established large-cap companies that the portfolio manager believes are growing their near-term earnings at an above average rate. The Fund defines a large-cap company as one having a market capitalization of $5 billion or more at the time of acquisition. The portfolio manager emphasizes valuation to find companies selling at a discount to their intrinsic value. These companies must pass an initial capitalization screen and:

The Fund may invest in foreign securities (directly and through depositary receipts).

To manage risk, the portfolio manager limits sector and individual security exposure, and adheres to a strong sell discipline.

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.

Credit Risk. Credit risk (also called default risk) is the risk that the issuer of a security will not be able to make principal and interest payments on a debt issue. The credit ratings of issuers could change and negatively affect the Fund’s share price or yield.

Foreign Securities Risk. Investing in the securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. companies. The securities of foreign companies may be less liquid and 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 and little public information about the companies. Trades typically take more time to settle and clear, and the cost of buying and selling foreign securities is generally higher than similar costs associated with U.S. traded securities.

The value of the securities held by the Fund may be affected by changes in exchange rates or control regulations. If a local currency gains against the U.S. dollar, the value of the holding 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 securities in 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.

Growth Style Risk. Growth investing involves buying stocks that have relatively high price-to-earnings ratios. Growth stocks may be more volatile than other stocks because they are generally more sensitive to investor perceptions and market moves. During periods of growth stock underperformance, the Fund’s performance may suffer.

Interest Rate Risk. If interest rates rise, bond prices will fall. The longer the maturity of a bond, the more sensitive a bond’s price will be to changes in interest rates. In other words, a long-term bond (30-year) will have greater price sensitivity than a short-term bond (2-year). Short-term and long-term bond prices and interest rates do not typically move the same amount or for the same reasons. Interest rate changes will impact high yield bonds in different ways depending on credit ratings. BB rated bonds are more vulnerable to prevailing rates and act more like their investment grade counterparts. For bonds rated B and below, credit risk is more significant than interest rate risk.

Liquidity Risk. When there is no willing buyer and investments 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 can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Recent instability in certain credit and fixed income markets has adversely affected and is expected to continue to affect the liquidity of certain asset classes of securities including, in particular, certain types of asset-backed, mortgage-backed and real-estate related securities. Less liquid securities are more difficult to dispose of at their recorded values and are subject to increased spreads and volatility.

Manager Risk. The performance of the Fund is dependent upon the investment adviser’s skill in selecting managers and the portfolio manager’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.

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

The following table indicates how the Fund’s average annual returns for different calendar periods compared to the returns of a broad-based securities market index.

After-tax returns are calculated using the highest historical marginal individual federal income tax rates and do not reflect the impact of state and local taxes. After-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class N shares. After-tax returns for Class I shares and Class R shares will vary.

Aston Asset Management, LP serves as investment adviser to the Fund. Montag & Caldwell, LLC (“Montag & Caldwell”) serves as the subadviser to the Fund.

Mr. Ronald E. Canakaris, President and Chief Investment Officer of Montag & Caldwell, has served as the Fund’s portfolio manager since November 1994.

Shares of the Fund may be purchased, exchanged, or redeemed on any business day by written request (Aston Funds, P.O Box 9765, Providence, RI 02940), wire transfer, online access (www.astonfunds.com), or by telephone (800-992-8151). Additional information may be required on certain redemptions. Investors who wish to purchase, exchange or redeem Fund shares through a broker-dealer should contact the broker-dealer directly.

Class R shares are only intended for use within retirement plans offered through a financial representative or a plan sponsor.

The Fund’s distributions are generally taxable as ordinary income or capital gains for federal income tax purposes, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account. Distributions on investments made through tax-deferred vehicles, such as 401(k) plans or IRAs, may be taxed later upon withdrawal of assets from those plans or accounts.

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
