Dear
      Board of Directors:





As
      stated
      in Note 2 to the consolidated financial statements of Icahn Enterprises L.P.
      and
      Subsidiaries (“Icahn Enterprises”) for the nine months and three months ended
      September 30, 2007, Icahn Enterprises changed its method of allocating gains
      and
      losses related to the disposition of common control acquired entities to third
      parties. While the undersigned believes that both the historical method and
      the
      new method of allocating such gains and losses are acceptable alternatives
      under
      generally accepted accounting principles and that audited financial statements
      for prior periods were correct in this regard, management believes the newly
      adopted accounting principle is preferable because of the reasons stated below.
      Based on our review and discussion, we concur with management’s judgment that
      the newly adopted accounting principle is preferable in the circumstances.
      In
      formulating this position, we are relying on management’s business planning and
      judgment, which we do not find unreasonable.





|· | Upon
              Icahn Enterprises’ acquisition of an entity under common control, Icahn
              Enterprises reflects the acquired entity in a manner similar to a pooling
              of interests. Icahn Enterprises’ general partner capital account is
              charged or credited with the difference between the consideration Icahn
              Enterprises pays for the entity and its predecessor basis prior to
              the
              acquisition by Icahn Enterprises. Upon later sale of such an entity
              to a
              third party, historically, the gain or loss was allocated between the
              general partner and limited partners in accordance with their respective
              percentage interests under the partnership agreement. The newly adopted
              accounting principle allocates this gain or loss by first restoring
              the
              general partner’s capital account for the cumulative charges or credits
              recorded during periods prior to the common control acquisition and
              then
              allocating the remaining gain or loss among the general and limited
              partners in accordance with their respective percentage interests under
              the partnership agreement. Under the newly adopted accounting policy,
              total partners’ equity, which is 98.01% attributable to the limited
              partners pursuant to the partnership agreement, will not change.
              Management believes that the newly adopted accounting method better
              reflects the economics of the transactions in the earnings per limited
              partner unit; and

|· | The
              newly adopted accounting method provides for the general partner’s capital
              accounts to be restored to their original 1.99% ownership basis per
              the
              partnership agreement.

At
      your
      request, we have reviewed and discussed with management the circumstances,
      business judgment, and planning that formed the basis for making this change
      in
      accounting principle.








It
      should
      be recognized that professional standards have not been established for
      selecting acceptable alternative principles that exist in this area or for
      evaluating the preferability of acceptable alternative accounting principles.
      Accordingly, we are furnishing this letter solely for purposes of Icahn
      Enterprises’ compliance with the requirements of the Securities and Exchange
      Commission, and it should not be used or relied on for any other
      purpose.





We
      have
      not audited any consolidated financial statements of Icahn Enterprises L.P.
      and
      Subsidiaries as of any date or for any period subsequent to December 31, 2006.
      Accordingly, we are unable to express an opinion on whether the method of
      accounting for the effect of the change is in conformity with accounting
      principles generally accepted in the United States of America or if the
      financial information included in Part I of this Form 10-Q is fairly
      presented.





Very
      truly yours,
