Form 10-K for the Year Ended December 31, 2023
Management's Discussion and Analysis of Financial Condition and Results of
Operations
Executive Summary, page 36

1.     When providing a discussion and analysis of a non-GAAP measure, please
ensure such
       disclosure is accompanied by a similar discussion and analysis of the
corresponding
       GAAP measure with equal or greater prominence. For example, you disclose
the decrease
       in segment Adjusted EBITDA YoY and Q4 over Q3 fiscal 2023 without
providing similar
       information for the corresponding GAAP measure. In addition, you
disclose total adjusted
       EBITDA for Q3 fiscal 2023 and Q4 fiscal 2022 without providing similar
GAAP
       information for net income. Refer to Item 10(e)(1)(i)(A) of Regulation
S-K and Question
       102.10(a) of the non-GAAP C&DIs.
2.     We note that you include various measures for the most recent quarter,
including new
       orders booked, book to bill ratio, and orders shipped on an individual
segment basis. In
       order to provide context to your current measure, please revise to
include comparative
       information for the periods presented in the filing. Refer to SEC
Release No. 33-10751.

3.     Please revise to explain in sufficient detail the reasons driving
changes in your financial
       statement line items on a consolidated and segment basis. When you
discuss revenue
       fluctuations, specifically describe the extent to which changes are
attributable to changes
       in prices, changes in the volume or amount of goods or services being
sold, or to the
       introduction of new products or services. Where you describe two or more
business
       reasons that contributed to a material change in a financial statement
line item between
       periods, please quantify, where possible, the extent to which each
factor contributed to the
       overall change in that line item, including any off-setting factors.
Also, revise to include a
       separate discussion of the company's consolidated results based on the
line items in your
       consolidated statements of income. Refer to Item 303(a) and (b) of
Regulation S-K and
       SEC Release No. 33-8350.

4.     You disclose that the company expects to recognize as revenue over the
next 12 months
       approximately $1.5 billion of the unsatisfied or partially satisfied
performance obligations
       with the remainder being recognized thereafter. Please revise to
disclose when the
       remaining $3 billion will be recognized on a quantitative basis using
time bands that
       would be most appropriate for the duration of the remaining performance
obligations or
       by providing qualitative information. Refer to ASC 606-10-50-13.
       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.
