In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to these comments within ten business days by providing the requested information or advise us as soon as possible when you will respond. If you do not believe our comments apply to your facts and circumstances, please tell us why in your response. After reviewing your response to these comments, we may have additional comments. Unless otherwise noted, references to our prior comments refer to comments in our letter dated September 4, 2018. 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 Albert Neupaver FirstName LastNameAlbert Neupaver Corporation Westinghouse Air Brake Technologies Comapany 2018 October 1, NameWestinghouse Air Brake Technologies Corporation October 1, 2018 Page 2 Page 2 FirstName LastName 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. Notes To Combined Financial Statements 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.
