As such, we do not believe they represent a material liquidity risk to the company.

Operating income also decreased due to a $330 million reduction in the FAS/CAS operating adjustment, which more than offset higher segment operating income and lower non-divestiture-related unallocated corporate expense. 2022 operating margin rate declined to 9.8 percent from 15.8 percent reflecting the items above. 2022 G&A costs as a percentage of sales increased to 10.6 percent from 10.1 percent, primarily due to an increase in investments for future business opportunities.
The decrease was also offset by $311 million of lower unallocated corporate expense, largely due to higher deferred state tax benefits associated with the MTM adjustment and B-21 charge and lower intangible asset amortization and PP&E step-up depreciation, as well as a $118 million reduction in the FAS/CAS operating adjustment. 2023 operating margin rate declined to 6.5 percent from 9.8 percent reflecting the items above. 2023 G&A costs as a percentage of sales decreased to 10.2 percent from 10.6 percent, primarily due to higher sales, which more than offset our continued investments for future business opportunities.
Operating margin rate decreased to 9.4 percent from 10.6 percent primarily due to lower net EAC adjustments and a $45 million write-down of commercial inventory, partially offset by a $96 million gain recognized in connection with a land exchange transaction. -40- NORTHROP GRUMMAN CORPORATION PRODUCT AND SERVICE ANALYSIS The following table presents product and service sales and operating costs and expenses by segment: Year Ended December 31 $ in millions 2022 2021 2020 Segment Information: Sales Operating Costs and Expenses Sales Operating Costs and Expenses Sales Operating Costs and Expenses Aeronautics Systems Product $ 7,981 $ 7,161 $ 9,408 $ 8,534 $ 10,437 $ 9,435 Service 2,311 2,042 1,662 1,462 1,610 1,417 Intersegment eliminations 239 212 189 170 122 111 Total Aeronautics Systems 10,531 9,415 11,259 10,166 12,169 10,963 Defense Systems Product 2,717 2,385 2,564 2,243 3,024 2,740 Service 2,056 1,819 2,423 2,137 3,791 3,305 Intersegment eliminations 806 711 789 700 728 652 Total Defense Systems 5,579 4,915 5,776 5,080 7,543 6,697 Mission Systems Product 7,376 6,291 7,064 6,017 6,744 5,757 Service 2,005 1,639 2,077 1,695 2,557 2,201 Intersegment eliminations 1,015 848 993 843 779 663 Total Mission Systems 10,396 8,778 10,134 8,555 10,080 8,621 Space Systems Product 10,448 9,455 8,832 7,898 6,810 6,084 Service 1,708 1,557 1,637 1,464 1,826 1,672 Intersegment eliminations 119 105 139 125 108 95 Total Space Systems 12,275 11,117 10,608 9,487 8,744 7,851 Segment Totals Total Product $ 28,522 $ 25,292 $ 27,868 $ 24,692 $ 27,015 $ 24,016 Total Service 8,080 7,057 7,799 6,758 9,784 8,595 Total Segment (1) $ 36,602 $ 32,349 $ 35,667 $ 31,450 $ 36,799 $ 32,611 (1) A reconciliation of segment operating income to total operating income is included in “Segment Operating Results.” Product Sales and Costs 2022 product sales increased $654 million, or 2 percent, primarily due to an increase in product sales at Space Systems, partially offset by a decrease in product sales at Aeronautics Systems.

We use industry multiples (including relevant control premiums) of operating earnings to corroborate the fair values of our reporting units determined under the market valuation method of the income approach. We test for impairment of our long-lived assets when events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable.

Current tensions within Congress and the wider U.S. political environment may also impact defense budgets and government spending more broadly. We believe the current global security environment highlights the significant national security threats to our nation and our allies, and the need for strong deterrence and a robust defense capability.
