Notes to Consolidated Financial Statements

Note 14: Contingencies

Asbestos-related Liability, page 95

1. We note your disclosure that you have made enhancements to the management
and analysis
   of asbestos-related claims, including the engagement of new national
coordinating council
   and new local counsel panels, outsourcing administration and claims
handling, implementing
   improvements in processing, and increasing audits and compliance reviews of
counsel
   handling asbestos-related claims. You state that this has resulted in
improvements in both
   the quantity and quality of information available and an increased ability
to reasonable
   forecast the number of potential future claims that may be asserted.

   You also state that you hired a third party consultant in the third quarter
of 2016 to further
   assist you in the analysis of potential future asbestos-related claims. It
appears that with the
   assistance of this external consultant and the updated data and analysis
resulting from your
   claims review process, you determined that your best estimate of the
aggregate liability both

    for asbestos-related claims asserted but not yet resolved and potential
asbestos-related claims
    not yet asserted, including an estimate for defense costs, is $879.3
million as of December
    31, 2016, which is $770.8 million higher than the prior year.

    Please tell us your consideration of accounting for this as a correction of
an error in
    previously issued financial statements rather than as a change in estimate.
Refer to ASC 250-
    10-20.

        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       You may contact Patrick Kuhn at (202) 551-3308 or me at (202) 551-3380
with any
questions.
