[1] Upon commencement of drilling operations, the MMSA for the managed rigs was suspended and replaced by a charter agreement for the duration of the contract. As a result, we reclassified $11.1 million previously recorded as a contract liability to “Contract advances,” which was reported as a component of “Accrued liabilities” in our Consolidated Balance Sheets at December 31, 2022.
