Management's Discussion and Analysis of Financial Condition and Results of Operations Adjusted Free Cash Flow, page 80 2. We note your adjustment for Adjusted FCF captioned "Expenses financed by an intermediary" and the related explanation in footnote (a) regarding hypothetical amounts. It is unclear to us why you reclassify amounts in the consolidated statements of cash flows based on hypothetical operating and financing transactions. Tell us the nature of expenses financed by an intermediary and your basis in the accounting literature for related reclassifications. Considering that the operating cash outflow for "Expenses financed by an intermediary" is hypothesized, it is unclear how such amount could be presented as a non-GAAP adjustment to net cash provided by operating activities. Such adjustment appears to have used an individually tailored recognition and measurement method. Please advise or revise. Refer to Q&A 100.04 of the CD&I on Non-GAAP Financial Measures. Form 8-K filed July 29, 2021 Liberty Global Reports Q2 2021 Results Footnotes, page 21 3. Refer to footnote 8 regarding Debt to LTM Adjusted EBITDA and Net Debt to LTM Adjusted EBITDA. Please present with equal or greater prominence, the most directly comparable financial ratios calculated and presented in accordance with GAAP. Include a reconciliation to such GAAP measures. Refer to Item 10(e)(1)(i)(A)-(B) of Regulation S- K and footnote 27 of the SEC s Adopting Release titled Conditions for Use of Non- GAAP Financial Measures (Release No. 33-8176). Liberty Global Reports Q2 2021 Results Glossary, page 23 4. We note that the OFCF ("Operating Free Cash Flow") is used to measure your performance though the term appears to denote that it is a liquidity measure. Inconsistency in the labeling of a non-GAAP measure is confusing and thus, may be potentially misleading to investors. Refer to Regulation G, Rule 100(b). Additionally, please reconcile this measure to its most comparable GAAP measure instead of another non-GAAP measure. 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. You may contact Kathryn Jacobson, Senior Staff Accountant at (202) 551-3365 or Robert Charles H. R.
