will

In

Form 10-Q for the period ended June 30, 2005

Management`s Discussion and Analysis, page 20

Operating Income, page 22

1.	We have read your response to the third comment in our letter
dated August 30, 2005 related to the deconsolidation of a joint
venture.  It is not evident to us that you controlled the joint
venture, in the manner contemplated by SFAS 94, prior to the
deconsolidation.  Therefore, please provide an analysis that
demonstrates in further detail how you controlled the joint
venture
given the guidance in SFAS 94, and tell us why you believe that
equity method accounting under APB 18 was not appropriate.  In
this
regard,
* Please tell us who the other investors are and whether they are
related to the primary customer supplied by the joint venture.
* Please provide us with a copy of the joint venture agreement and
any other relevant contracts.



* You appear to have concluded that the joint venture is a voting
interest entity, as opposed to a variable interest entity.  Please
tell us your consideration of paragraph 5 of FIN 46R in reaching
this
conclusion.
* Identify the material rights and obligations, as stated in the
joint venture agreement, possessed by each of the investors and
explain how such rights are consistent with your determination
that
you had control as contemplated by SFAS 94.  In addition, address
the
following:
o Identify the governing body, the number of members on this body,
and the rights of each investor to appoint and remove these
members.
o Describe the ability of each investor to participate in
operating
and capital decisions.  We note your discussion regarding the role
of
the Chairman of the Joint Venture and the role of the Company with
respect to certain changes in operational and capital budget
decisions.  However, please clarify the rights held by the other
investors if they disagreed with the actions of the Chairman of
the
Joint Venture or you.
o Clarify who, if anyone, has the unilateral authority to
establish
business relationships, employee compensation, and financial
forecasts/budgets.
o Whether you have any puts, calls, or rights of first refusal
over
the interests of the other investors.
In your response, please cite the specific paragraphs in the joint
venture agreement on which you rely.
* Please tell us if you have any other investments where you are
consolidating despite a less than majority equity interest.  If
so,
please quantify for us the impact of consolidation for each of
these
entities.

Form 8-K filed August 25, 2005

2.	We note here your use of return on invested capital (ROIC), a
non-GAAP financial measure, which we questioned in our letter
dated
March 2, 2005.  We note your intended compliance in your response
to
that letter.  We remind you in future filings to expand your
discussion to more specifically address why you believe ROIC to be
a
useful measure in providing investors with information regarding
the
Company`s performance.  Refer to Item 10(e)(i)(C) of Regulation S-
K.
