Basis of Financial Statement Presentation | (1) Basis of Financial Statement Presentation The accompanying condensed balance sheet as of September 30, 2014, which has been derived from audited financial statements, and the unaudited interim condensed financial statements as of June 30, 2015 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission and include the accounts of Hennessy Advisors, Inc. (the “Company”). Certain information and footnote disclosures in these unaudited interim condensed financial statements, normally included in financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission for Quarterly Reports on Form 10-Q. In the opinion of management, the unaudited interim condensed financial statements reflect all adjustments, consisting only of normal, recurring adjustments, necessary for a fair presentation of the Company’s financial position at June 30, 2015, the Company’s operating results for the three and nine months ended June 30, 2015 and 2014, and the Company’s cash flows for the nine months ended June 30, 2015 and 2014. These unaudited interim condensed financial statements and notes should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended September 30, 2014, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2014. The Company’s operating activities consist primarily of providing investment advisory services to sixteen open-end mutual funds commonly referred to as the Hennessy Funds. The Company serves as the investment advisor to all classes of the Hennessy Cornerstone Growth Fund, the Hennessy Focus Fund, the Hennessy Cornerstone Mid Cap 30 Fund, the Hennessy Cornerstone Large Growth Fund, the Hennessy Cornerstone Value Fund, the Hennessy Large Value Fund, the Hennessy Total Return Fund, the Hennessy Equity and Income Fund, the Hennessy Balanced Fund, the Hennessy Core Bond Fund, the Hennessy Gas Utility Fund, the Hennessy Small Cap Financial Fund, the Hennessy Large Cap Financial Fund, the Hennessy Technology Fund, the Hennessy Japan Fund, and the Hennessy Japan Small Cap Fund. The Company also provides shareholder services to the entire family of Hennessy Funds. Prior to March 1, 2015, the Company only earned shareholder servicing fees from some of the Hennessy Funds. The Company’s operating revenue consists of contractual investment advisory and shareholder service fees paid to it by the Hennessy Funds. The Company earns investment advisory fees from the Hennessy Funds by, among other things, managing the composition of each Hennessy Fund’s portfolio (including the purchase, retention, and disposition of portfolio securities in accordance with the applicable Hennessy Fund’s investment objectives, policies, and restrictions), conducting investment research, monitoring compliance with each applicable Hennessy Fund’s investment restrictions and applicable laws and regulations, overseeing service providers (including sub-advisors), maintaining an in-house public relations and marketing program for each of the Hennessy Funds, preparing and distributing regulatory reports, and overseeing distribution through third-party financial intermediaries. The Company earns shareholder service fees from the Hennessy Funds by, among other things, maintaining an “800” number that the current investors of the Hennessy Funds may call to ask questions about the Hennessy Funds or their accounts, or to get help with processing exchange and redemption requests or changing account options. These fee revenues are earned and calculated daily by the Hennessy Funds’ accountants at U.S. Bancorp Fund Services, LLC. The fees are computed and billed monthly, at which time they are recognized in accordance with Accounting Standard Codification 605 “Revenue Recognition.” In the past, the Company has waived fees with respect to some of the Hennessy Funds to comply with contractual expense ratio limitations, but all such expense ratio limitations expired or were terminated as of February 28, 2015. The fee waivers were calculated daily by the Hennessy Funds’ accountants at U.S. Bancorp Fund Services, LLC and were charged to expense monthly by the Company as an offset to revenue. The waived fees were deducted from investment advisory fee income and reduced the amount of advisory fees that the Hennessy Funds paid in the subsequent month. To date, the Company has only waived fees based on contractual obligations, but the Company has the ability to waive fees at its discretion to compete with other mutual funds with lower expense ratios. If the Company were to elect voluntarily to waive fees, the decision to waive fees would not apply to previous periods, but would only apply on a going forward basis. As of June 30, 2015, the Company has never voluntarily waived fees. The Company’s contractual agreements for investment advisory and shareholder services provide persuasive evidence that an arrangement exists with fixed and determinable fees, and the services are rendered daily. The collectability is probable as the fees are received from the Hennessy Funds in the month subsequent to the month in which the services are provided. |
