Item 7.01         Regulation FD Disclosure
                  ------------------------

Hennessy Advisors, Inc. announced that on September 9, 2005 the shareholders of
each of the mutual funds it advises approved new investment advisory agreements
for Hennessy to continue managing the funds following completion of Hennessy's
pending public offering. Fund shareholders were required to approve the new
agreements because completion of the offering will be deemed to result in a
change in control of Hennessy. If the pending public offering is not completed,
the current investment advisory agreements will remain in effect. The new
agreements are identical to the current agreements, except for the dates of
execution and termination, and thus are not being filed as exhibits to this Form
8-K.
