Check  the  appropriate  box  below  if the  Form  8-K  filing  is  intended  to
simultaneously  satisfy the filing obligation of the registrant under any of the
following provisions (see General Instruction A.2. below):

     |_| Written communications pursuant to Rule 425 under the Securities Act
(17 CFR 230.425)

     |_| Soliciting material pursuant to Rule 14a-12 under the Exchange Act (17
CFR 240.14a-12)

     |_| Pre-commencement communications pursuant to Rule 14d-2(b) under the

     |_| Pre-commencement communications pursuant to Rule 13e-4(c) under the
Exchange Act (17 CFR 240.13e-4(c))



Item 8.01 OTHER EVENTS.

     Effective as of January 1, 2006,  the Fund's  monthly asset based fees will
be calculated at a rate of 1/12 of the applicable  annual fee rate,  rather than
by a ratio of days in a month over days in the year.  This change in calculation
method may result in differences in the amount of fees paid in a give month, but
the general partner expects that such variances will be minor over the course of
a year.

     Pursuant to the  requirements  of the Securities  Exchange Act of 1934, the
