Unless we note otherwise, our references to prior comments are to comments in our March 16, 2021 letter. Form 10-K for the Fiscal Year Ended August 29, 2020 Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations Reconciliation of Non-GAAP Financial Measures: Adjusted After-tax ROIC and Adjusted Debt to EBITDAR, page 38 1. We note your response to our prior comment #1. We understand that the excess cash arose as a result of unique circumstances related COVID-19. We further note your belief that in post-pandemic periods you do not expect to maintain excess cash and therefore do not expect to present debt or average debt, net of excess cash or average excess cash, respectively. However, it is not appropriate to present and label your amounts as debt and average debt with titles that are similar to GAAP titles. If you present these measures in future filings, please revise your disclosure accordingly. Please refer to Item 10(e)(1)(ii)(E) of Regulation S-K for further guidance. Jamere Jackson AutoZone, Inc.
