Investment Objective

The Hennessy Balanced Fund seeks a combination of capital appreciation and current income.

Fund Fees and Expenses

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

SHAREHOLDER FEES
(fees paid directly from your investment)		None
ANNUAL FUND OPERATING EXPENSES
(expenses that you pay each year as a percentage of the value of your investment)
Management Fees		0.60%
Distribution and Service (12b-1) Fees		0.15%
Other Expenses		1.08%
Shareholder Servicing	0.10%
Remaining Other Expenses1	0.98%
Total Annual Fund Operating Expenses		1.83%

¹ Includes acquired fund fees and expenses that do not exceed 0.01% of the Fund’s average daily net assets.  Acquired fund fees and expenses are not reflected in the Fund’s financial statements, with the result that the information presented in the expense table may differ from that presented in the financial highlights.

EXAMPLE

This Example is intended to help you compare the cost of investing in shares of this 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. The Example also assumes that you reinvest all dividends and distributions, 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 the assumptions, your costs would be:

One Year	Three Years	Five Years	Ten Years
$186	$576	$990	$2,148

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 had a portfolio turnover rate of 31% of the average value of its portfolio.

Principal Investment Strategy

The Fund invests approximately 50% of its assets in roughly equal dollar amounts in the 10 highest dividend-yielding Dow Jones Industrial Average (“DJIA”)* stocks (known as the “Dogs of the Dow”), but limits exposure to market risk and volatility by investing approximately 50% of its assets in U.S. Treasury securities with a maturity of less than one year.

The total portfolio is divided into multiple sub-portfolios, each of which uses the Dogs of the Dow strategy. On various dates throughout the year, each of these sub-portfolios are reviewed. In a review, the Investment Manager determines the 10 highest yielding common stocks in the DJIA by annualizing the last quarterly or semi-annual ordinary dividend declared on each stock and dividing the result by the market value of that stock. The Fund then purchases those stocks in approximately equal amounts for the sub-portfolio being reviewed. The Fund also may purchase from time to time an approximately equal amount of U.S. Treasury securities having a remaining maturity of less than one year for the sub-portfolio being reviewed. On the next date, another sub-portfolio is reviewed in a similar manner.

The Fund generally holds the stock investments within each sub-portfolio for one year, upon which time, the applicable sub-portfolio is up for another review. The Fund generally holds the stock investments within each sub-portfolio for one year regardless of whether they remain in the DJIA or retain the characteristics of Dogs of the Dow stocks. At the end of the one-year period, the Fund sells any stocks in the applicable sub-portfolio that are no longer Dogs of the Dow stocks and replaces them with stocks that are Dogs of the Dow stocks. Additionally, it may sell a portion of the stocks that remain in the applicable sub-portfolio so that the rebalanced portion of the applicable sub-portfolio adheres to the Fund’s asset allocation strategy.

* The Dow Jones Industrial Average is the property of the Dow Jones & Company, Inc. Dow Jones & Company, Inc. is not affiliated with the Hennessy Funds or its investment advisor. Dow Jones & Company, Inc. has not participated in any way in the creation of the Hennessy Funds or in the selection of stocks included in the Hennessy Funds and has not approved any information included in the Prospectus.

Principal Risks

Although approximately 50% of the Fund’s portfolio is invested in U.S. Treasury securities, there are market and investment risks associated with an investment in the Fund, as there are with any security. The value of your investment will fluctuate over time, and it is possible to lose money. The principal risks of investing in the Fund include the following:

Market and Equity Investments Risk: The market value of a security may move up or down, and these fluctuations may cause a security to be worth more or less than the price originally paid for it. Market risk may affect a single company, an industry, a sector of the economy, or the market as a whole. The value of equity securities

will fluctuate due to many factors, including the past and predicted earnings of the issuer, the quality of the issuer’s management, general market conditions, forecasts for the issuer’s industry, and the value of the issuer’s assets.

Formula Investing Risk: The Fund will adhere to its strategy during the course of the year, subject to applicable Securities and Exchange Commission requirements and federal tax requirements relating to mutual funds, despite any adverse developments that may arise. This could result in substantial losses to the Fund if, for example, the stocks selected for the Fund’s portfolio for a given year are experiencing financial difficulty or are out of favor with investors. The Fund’s portfolio is rebalanced annually in accordance with its strategy, which may result in the sale of securities that have been performing well in the near term and the purchase of securities that have been performing less well in the near term.

Non-Diversification Risk: Because the Fund is non-diversified (meaning that compared to diversified mutual funds, the Fund may invest a greater percentage of its assets in a more limited number of issuers), the Fund’s shares may be more susceptible to adverse changes in the value of a particular security than would be the shares of a diversified mutual fund. Thus, the Fund may be more volatile because each stock in which it invests could have a greater impact on the Fund’s performance.

Performance Information

The following performance information provides some indication of the risks of investing in the Hennessy Balanced Fund by showing changes in its performance from year to year and how the Fund’s average annual returns for one, five, and ten years compare with those of an index that reflects a broad measure of market performance, the DJIA, as well as an additional index that reflects the types of securities in which the Fund invests, the 50/50 Blended DJIA/Treasury Index (which consists of 50% common stocks represented by the DJIA and 50% short-duration Treasury securities represented by the ICE BofAML 1-Year Treasury Note Index).  For additional information on these indices, please see “Descriptions of Indices” on page 61 of the Prospectus. The Fund is the successor to the Hennessy Balanced Fund, a series of The Hennessy Funds, Inc. (the “Predecessor Balanced Fund”). The performance information provided for the periods on or prior to February 28, 2014, is historical information for the Predecessor Balanced Fund, which was managed by the same investment adviser and had the same investment objective and investment strategy as the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of future performance. Performance may be higher or lower in the future. Updated performance information is available on the Hennessy Funds’ website (hennessyfunds.com).

We use the 50/50 Blended DJIA/Treasury Index as an additional index because it compares the Fund’s performance with the returns of an index reflecting the performance of investments similar to those of the Fund.

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

Investment Manager

Hennessy Advisors, Inc. is the investment manager of the Fund.

Portfolio Managers

Neil J. Hennessy and Brian E. Peery are primarily responsible for the day-to-day management of the portfolio of the Fund and for developing and executing the Fund’s investment program. Mr. Hennessy serves as a Portfolio Manager of the Fund, and has been the Chief Executive Officer and Chairman of the Board of Directors of the Investment Manager since its organization in 1989.  Mr. Peery has served as a Portfolio Manager of the Fund since October 2014, served as a Co-Portfolio Manager of the Fund from February 2011 through September 2014, and has been employed by the Investment Manager since 2002.

Tax Information

The Funds’ distributions generally will be taxable to you, whether they are paid in cash or reinvested in Fund shares, unless you invest through a tax-deferred arrangement, such as a 401(k) plan or an IRA, in which case such distributions may be taxable at a later date.

Payments to Broker-Dealers and Other Financial Intermediaries

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