We note your presentation of consolidated and segment gross profit excludes charges for depreciation, amortization, and accretion. Your current disclosure of gross profit on a consolidated basis outside of the segment footnote is a non-GAAP measure.

See Item 10(e) of Regulation S-K. INDEX TO CONSOLIDATED FINANCIAL STATEMENTS 19. Segment Reporting , page F-30 2. You report Adjusted EBITDA, which you disclose is the Partnership's segment measure of performance, gross profit, operating income and net income for each of your reportable Dylan Bramhall Sunoco LP May 18, 2022 Page 2 segments. If your chief operating decision maker uses only one measure of a segment's profit or loss in assessing segment performance and deciding how to allocate resources, segment profit or loss shall be reported for that measure only. If the chief operating decision maker uses more than one measure of a segment's profit or loss, the reported measure shall be the one that management believes is determined in accordance with the measurement principles most consistent with those used in measuring the corresponding amount in the public entity's consolidated financial statements. Refer to ASC 280-10-50- 28. 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.
