Item 8.01.  Other Events

     On December 20, 2004,  Ashland issued a press release  announcing that
the  Internal  Revenue  Service  (IRS) has now  indicated  that it does not
intend to provide all the rulings  requested  by Ashland  Inc. and Marathon
Oil  Corporation  in  the  proposed   transaction  to  transfer   Ashland's
38-percent interest in Marathon Ashland Petroleum LLC (MAP) to Marathon.
     As  previously  announced  in  March  2004,  Ashland  entered  into an
agreement with Marathon through which Ashland would transfer its 38-percent
interest  in MAP  to  Marathon.  The  transaction  is  subject  to  several
previously disclosed  conditions,  including receipt of a favorable private
letter  ruling  from  the IRS  with  respect  to the tax  treatment  of the
transaction.  Earlier this year, Ashland submitted a request to the IRS for
a private letter ruling on the tax treatment of the transaction.
     Ashland reported in its Form 10-K filing on December 14, 2004, that it
had  engaged in  discussions  with the IRS with  respect to the complex tax
issues related to this transaction and had not resolved all issues. At that
time,  Ashland  reported  that it could not predict  whether the  requested
rulings would be received.
     The IRS has now  indicated  that it does not intend to provide all the
rulings requested by Ashland and Marathon. As previously disclosed, Ashland
might have incurred  Section  355(e) gain on the  transaction  equal to the
difference  between the fair  market  value of Ashland and the tax basis of
Ashland. One of the IRS rulings requested was that the tax basis in Ashland
not be reduced by the assumption of contingent  liabilities associated with
discontinued  business  operations  in a way that  would  cause  additional
Section  355(e) gain to be  recognized.  The IRS has  informed  Ashland and
Marathon  that it  intends to rule  adversely  on this  specific  tax basis
issue.  Under the IRS' indicated  position on this issue,  the basis of the
Ashland  shares  would  be  reduced  by  the  amount  of  such   contingent
liabilities  in a manner that would likely  create  significant  additional
Section  355(e) gain.  Ashland  believes that the IRS would grant all other
requested rulings that are conditions to closing the transaction.
     Ashland and Marathon disagree with the IRS' position on the contingent
liabilities  issue and will attempt to further  discuss this issue with the
IRS.  However,  Ashland  believes that it is unlikely  that the  previously
announced   

                                    -2-



transaction  will  close.  Ashland  remains  pleased  with  its
ownership  interest  in MAP and,  therefore,  does  not  have any  plans to
exercise its option to put its interest in MAP to Marathon. Nonetheless, if
the previously announced transaction does not close, Ashland would consider
other alternatives for the transfer of its interest to Marathon. There is a
substantial  risk  that  no  acceptable  alternative  transaction  will  be
identified.

Exhibit 99.1.
