Form 10-Q for Fiscal Quarter Ended June 30, 2024 Financial Statements Condensed Consolidated Statements of Operations, page 4 1. We read your response to prior comment 1. Please confirm you stopped using equity method accounting for the joint venture after you sold 100% of your equity interest in it in August 2018. Per page 44 of your 2018 Form 10-K, after you sold your equity method investment, you agreed to a lease extension for the Magnolia, TX property through 2020. At the end of the lease term, tell us the specific asset category to which this asset was reclassified (or would have been reclassified, if your net investment in the lease happened to be zero), the applicable GAAP literature (e.g., ASC 360) and how you applied it. Refer to ASC 842-30-35-5. Furthermore, tell us specifically why this asset was not a long-lived asset, if true, and explain in greater detail why ASC 610-20-45-1 and ASC 360-10-45-5 did not apply.
