so we may better understand your disclosure.

       Please respond to these comments within ten business days by providing

Schedule 14A Filed September 17, 2018

Cash Flows
Six Months Ended June 30, 2018 Compared to Six Months Ended June 30, 2017
Operating Activities, page 163

1.    Please clarify the analysis in regard to how the factors disclosed
directly affect cash
      regarding the variance in net cash flows of operating activities.
References to results of
      operations, which are prepared on the accrual basis of accounting,
noncash items (e.g.,
      deferred income taxes) and working capital items may not provide a
sufficient basis for an
      investor to fully understand how cash was actually impacted by operating
activities. The
      disclosure should address the drivers underlying each factor cited. Refer
to the guidance

         previously cited for further information. Make conforming changes to
the fiscal year end
         operating cash flow analysis, as appropriate.
Unaudited Pro Forma Condensed Combined Financial Statements, page 171

2.       Please clarify how the amounts presented for notes 7(d) and 7(k) in
the pro forma
         condensed combined statements of income for the six months ended June
30, 2018 are
         consistent with the amounts within these notes on pages 178 and 179,
respectively.
3.       Refer to the pro forma condensed combined balance sheet as of June 30,
2018. It appears
         from the description of note 7(h) on page 178 this note should be
associated with the
         "deferred income taxes" line within "other assets" rather than "other
noncurrent assets,"
         and the amount of $64.4 should be in the "pro forma adjustments"
column rather than the
         "reclassification adjustment" column. This revised presentation
appears to be consistent
         with the presentation stated in this note for the "deferred income
taxes" line within
         "liabilities." Please revise or advise.
4.       In the notes to pro forma statements, please clarify how notes 7(b),
7(c) and 7(g) support
         the amount of $(127.2) in the "pro forma adjustments" column for "cash
and cash
         equivalents."
5.       In the notes to pro forma statements, please clarify how notes 7(c)
and 7(g) support the
         amount of $2,810.7 in the "pro forma adjustments" column for
"long-term debt."
6.       For note 7(d) on page 178, please quantify the amount of this
adjustment for the year
         ended December 31, 2017 attributed to each of "cost of goods sold" and
"cost of services
         sold" to which it relates in order to discern the amounts attributed
to note 7(a) for these
         line items.
7.       For note 7(i) on page 178, please quantify the amount of this
adjustment attributed to each
         of current "other accrued liabilities" and "other long term
liabilities" to which it relates in
         order to discern the amounts attributed to note 7(a) for these line
items.
8.       For note 7(m) on page 179, please quantify the amount attributed to
"additional paid in
         capital" in order to discern the amount attributed to note 7(a) for
this line item.

Note 3. Revenue Related To Contracts With Customers
Manner In Which Contract Modifications Are Treated, page F-21

9.       It is disclosed on page F-21 that contract modifications that
significantly change the scope
         and/or price of contracts are accounted for prospectively. Please
explain to us how this
         treatment complies with the guidance on contract modifications in ASC
606-10-25-10
         through 13 and ASC 606-10-32-45.

10.   We note your response to prior comment 26. Please consider disclosing
information
      consistent with your response, as this appears it may be material to
shareholders'
      understanding of the business to be acquired. Since the business to be
acquired appears to
      continue to have foreign operations, please discuss within the filing the
reorganization of
      foreign operations and its anticipated impact on future operations.
Note 19. Segment Information And Major Customers, page F-36

11.   The measure "operating income" is referred to on pages F-37 and F-60 but
it is not
      presented in the statement of earnings. Please explain what operating
income consists of.
12.   Operating income is also referred to on pages F-21 and F-52. Please tell
us and disclose
      as appropriate if this measure on these pages is consistent with
"operating income"
      referred to in the segment note. If not, please disclose what operating
income on these
      pages consists of and revise the label of either the measure on these
pages or in the
      segment note to prevent confusion to shareholders. Additionally, please
consider Item
      10(e)(1)(ii)(E) of Regulation S-K in labeling this measure on these pages
and in the
      segment note.
