Note 21.2) Other Equity Reserves and Subordinated Units, page F-88 5. We note your response to comment 16 regarding the classification of your $1 billion of 5.125% subordinated notes as equity instruments under IFRS and have the following comments: Explain in more detail why you believe you do not have a contractual obligation to deliver cash to the bondholders, as discussed in paragraphs 11 and 13 of IAS 32, notwithstanding the fact that there is not a stated maturity date. In this regard, we note that the Indenture for these Notes, filed as exhibit 4.6 to your Form 20-F for the year ended December 31, 2022, contains an Exhibit A showing the form of face of the Note and indicates that you have promised to pay the principal sum of the notes upon redemption. We note per the Indenture that the entire principal amount of all of the Notes and any accrued interest is automatically accelerated and becomes immediately due and payable in case of a bankruptcy or liquidation event. Tell us how you concluded that this provision does not result in a contractual obligation to deliver cash to another entity. Explain in more detail how you concluded that the subordinated notes meet the definition of an equity instrument as defined in paragraph 11 of IAS 32. In this regard, it is unclear from the Indenture how these Notes evidence a residual interest in your assets after deducting all liabilities since upon a bankruptcy or liquidation event, the principal and interest becomes immediately due and payable, and no payments can be made to holders of any class of your capital stock until all due and unpaid amounts have been paid to all holders of the Notes. You may contact Charles Eastman at (202) 551-3794 or Andrew Blume at (202) 551- 3254 with any questions. Maher Al-Haffir CEMEX S.A.B. de C.V.
