   1.                                                   We note your disclosure 
on page 30 that your ability to repay debt and pay dividends
                                                        "depends on the 
continued transfer to it of dividends and other income and funds from its
                                                        subsidiaries" and that 
the ability of your "subsidiaries to pay dividends and make loans
                                                        and other transfers to 
it is generally subject to various regulatory, legal and economic
                                                        limitations." Please 
explain to us your consideration of the applicability of Rules 4-08(e),
                                                        5-04(c) Schedule I and 
12-04 of Regulation S-X to your filing.

   2.                                                   We note that you 
quantify consolidated EBITDA margin on page 58 without presenting a
                                                        comparative IFRS 
measure with equal or greater prominence and that you have not
                                                        reconciled the measure 
to IFRS. Please revise future filings to present the IFRS measure
                                                        with equal or greater 
prominence and reconcile the measure to IFRS. Refer to

of the Compliance
         and Disclosure Interpretations on Non-GAAP Financial Measures.
Operating and Financial Review and Prospects
Overview, page 148

3.       We note that you present a "Continuing operations" revenues line item 
in the table on
         page 149 and a similar line item called "Revenues from continuing 
operations before
         eliminations resulting from consolidation" in the table on page 169. 
Considering these
         revenue amounts include intracompany revenues, they appear to 
represent individually
         tailored non-IFRS measures. Accordingly, please remove these line 
items from future
         filings. Refer to Question 100.04 of the Compliance and Disclosure 
Interpretations on
         Non-GAAP Financial Measures.
Year Ended December 31, 2022 Compared to Year Ended December 31, 2021, page 167

4.       We note that your results of operations disclosures predominantly 
discuss segment
         revenues inclusive of intragroup amounts, or "before eliminations 
resulting from
         consolidation." Considering revenues inclusive of intragroup amounts 
appear to represent
         individually tailored non-IFRS measures pursuant to Question 100.04 of 
the Compliance
         and Disclosure Interpretations on Non-GAAP Financial Measures, please 
tell us why you
         believe it is appropriate to disclose such measures. Ensure that you 
revise your
         disclosures in future filings to present and discuss segment revenues 
from external
         customers. To the extent you wish to discuss segment intragroup 
revenues, consider
         providing a separate discussion of such amounts.
5.       We note that the second and third sentences of footnote (1) on pages 
168, 188, 190, and at
         the top of page 170 discuss variations in local currency terms for 
purposes of a reporting
         segment consisting of a region. Please clarify for us what this 
statement means and revise
         your disclosures accordingly.
Sources and Uses of Cash, page 209

6.       Please provide a more informative discussion and analysis of cash 
flows from operating
         activities, including changes in working capital components, for the 
periods presented. In
         doing so, explain the underlying reasons and implications of material 
changes between
         periods to provide investors with an understanding of trends and 
variability in cash flows.
         Also ensure that your disclosures are not merely a recitation of 
changes evident from the
         financial statements. Refer to Item 303(a) of Regulation S-K and SEC 
Release No. 33-
         8350.
Notes to the Consolidated Financial Statements
4.2) Discontinued Operations, page F-31

7.       We note that you have classified several disposed businesses within 
discontinued
         operations. Tell us in sufficient detail how the dispositions 
qualified for discontinued

         operations classification pursuant to IFRS 5.32. In particular, 
explain how you
         determined the disposals represented separate major lines of business 
or geographical
         area. Per the table on page F-32, we note that revenues of all 
discontinued operations on a
         combined basis were not material to consolidated revenues.
4.3) Selected Financial Information by Reportable Segment and Line of Business, 
page F-32

8.       Although you disclose that your operations are organized in four 
regions each under the
         supervision of a regional president, it appears that the individual 
countries and combined
         "rest of" countries listed in your segment tables represent your 
reportable segments.
         Please revise your disclosures to clearly identify your reportable 
segments. Pursuant to
         IFRS 8.22(a), also disclose whether operating segments have been 
aggregated to form any
         reportable segments.
9.       Please tell us if your chief operating decision maker uses both 
"Operating EBITDA" and
         "Operating earnings before other expenses, net" in assessing segment 
performance and
         deciding how to allocate resources.
10.      You disclose on page F-33 that certain countries have been aggregated 
into a reportable
         segment due to "similar regional and economic characteristics and/or 
materiality." Please
         tell us how your aggregation policy complies with IFRS 8.14, which 
allows for combining
         operating segments that do not meet the quantitative thresholds with 
others that do not
         meet the quantitative thresholds to produce a reportable segment only 
if the operating
         segments have similar economic characteristics and share a majority of 
the aggregation
         criteria in IFRS 8.12. As currently worded, your disclosure suggests 
that an immaterial
         operating segment may be combined with one that does not share similar 
economic
         characteristics and a majority of the aggregation criteria, or with 
another immaterial
         operating segment, solely due to immateriality.
11.      Pursuant to IFRS 8.28, revise your segment tables on pages F-33 and 
F-34 in future filings
         to provide a total for your reportable segments and reconcile such 
totals to the
         corresponding consolidated amounts. Please note that the "Others" 
category presented
         under IFRS 8.16 should not be included in the reportable segment 
totals.
12.      We note that your tables on pages F-33 and F-34 combine amounts from 
continuing
         operations and discontinued operations, including revenues. Please 
note that it generally
         is not appropriate to present non-IFRS measures combining the amounts 
of continuing and
         discontinued operations. Accordingly, confirm that you will refrain 
from presenting such
         non-GAAP measures in future filings. Refer to Question 100.04 of the 
Compliance and
         Disclosure Interpretations on Non-GAAP Financial Measures.
13.      We note that your "Others" category represents a material portion of 
"Revenue (including
         intragroup transactions)." Pursuant to IFRS 8.16, please disclose the 
sources of the
         revenues included within this category. In particular, disclose the 
specific nature of
         the intragoup revenues.

14.      For cash-generating units ("CGUs") at risk of impairment, such as your 
United States and
         Spain operating segments discussed on page F-55, disclose pursuant to 
IAS
         36.134(f)(i) the amount by which each CGU's recoverable amount exceeds 
its carrying
         amount.
19) Pensions and Post-Employment Benefits, page F-74

15.      We note your disclosure on page F-78 that you participate in 
multiemployer defined
         benefit pension plans. Please tell us and disclose your accounting 
policy for
         multiemployer pension plans. Also provide the disclosures required by 
IAS 19.33(b).
Note 21.2) Other Equity Reserves and Subordinated Units, page F-88

16.      We note your disclosure on page F-89 that you issued $1 billion of 
5.125% subordinated
         notes with no fixed maturity date and determined that the notes 
qualify as equity
         instruments under applicable IFRS. Please tell us in sufficient detail 
how you determined
         the notes should be classified within stockholders' equity. Within 
your response, tell us
         the business purpose of the arrangement and what benefits, if any, 
accrue to the
         noteholders.
22) Executive Share-Based Compensation, page F-91

17.      Please provide all relevant disclosures required by paragraphs 44 
through 52 of IFRS 2. If
         you believe certain disclosures are not material for disclosure, 
please tell us how you
         arrived at such determination.
23) Earnings (Loss) Per Share, page F-92

18.      We note your disclosure that the number of diluted shares resulting 
from
         your executive stock-based compensation programs is determined using 
the inverse
         treasury method. Please clarify for us how you calculate diluted 
shares under the inverse
         treasury method. Also tell us why you do not use the treasury share 
method and how you
         determined the inverse treasury method was appropriate.
       In closing, 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.
