CY2022	us-gaap	Noncash Investing And Financing Activities Related Text NoncashInvestingAndFinancingActivitiesRelatedText	During the year ended December 31, 2022, the company acquired $46 million of internal use software through long-term financing directly with the supplier. The software was recorded in PP&E as a non-cash investing activity and the related liability was recorded in long-term debt as a non-cash financing activity. During the years ended December 31, 2022 and 2021, the company received lease incentives for landlord funded leasehold improvements of $96 million and $150 million, respectively, related to a Space Systems real estate lease, which were recorded in PP&E and included in non-cash investing activities. On December 28, 2022 the company acquired certain leased land in exchange for company-owned land, which had been used previously for production-related activities at Space Systems. The exchange was accounted for as a nonmonetary transaction, and the acquired land, valued at approximately $155 million, was recorded in PP&E as a non-cash investing activity. The transaction resulted in a $96 million gain, which was reflected in operating costs and expenses in the consolidated statements of earnings and comprehensive income.Non-cash investing activities also include capital expenditures incurred but not yet paid of $113 million, $91 million and $72 million as of December 31, 2022, 2021 and 2020, respectively.
