Sale of Business	Sale of Businesses Sale to Dresser On November 2, 2021, Itron entered into a definitive securities and asset purchase agreement to sell certain Gas product lines from our Device Solutions manufacturing and business operations in Europe and North America to Dresser. The sale included one German subsidiary – Itron GmbH along with its business operations, personnel, and the owned manufacturing facility in Karlsruhe; the business operations, personnel, and assets associated with the leased manufacturing facility in Argenteuil, France; and the business and manufacturing assets maintained at one of our contract manufacturers in North America. The base sale price of this divestiture was $75.0 million, with adjustments for (1) pension liabilities assumed by Dresser for related active employees and (2) the final working capital balance. Cash proceeds from the sale were $55.9 million. The transaction closed on February 28, 2022. The final sales price and loss on sale were determined after the finalization of the working capital adjustment, recognized in the fourth quarter of 2022. As of December 31, 2021, we recognized a pre-tax impairment loss of $34.4 million as well as $3.1 million for professional services in conjunction with the planned sale to Dresser (classified within loss on sale of businesses within the Consolidated Statements of Operations). In determining the amount of the impairment loss for the assets of this transaction during the fourth quarter of 2021, we included $59.7 million of accumulated foreign currency translation losses and $0.9 million in unrealized loss on defined benefit pension plans, both classified within AOCI. Upon closing of the sale transaction in the first quarter of 2022, the then outstanding amounts in AOCI were reclassified to net income through loss on sale of businesses for a total of $55.4 million, with a corresponding reversal of the impairment loss originally booked in the fourth quarter of 2021. The difference between the amounts included for the impairment loss in the fourth quarter of 2021 and the first quarter of 2022 was driven by the change in the euro to U.S. dollar exchange rate, and operating results for the period owned in 2022. During 2022, we recognized a total loss of $3.5 million related to adjustments to the working capital balances and additional professional services. We recognized a total loss of $0.7 million in 2023 in other charges related to the finalization of the transaction. Latin America Divestiture On June 25, 2020, we closed on the sale of five subsidiaries comprising our manufacturing and sales operations in Latin America to buyers led by Instalación Profesional y Tecnologías del Centro S.A. de C.V., a Mexican company doing business as Accell in Brazil (Accell), through the execution of various definitive stock purchase agreements. The total sales price of $35.0 million included deferred payments of $21.1 million for working capital, which was to be paid in full by December 31, 2020, as evidenced by a promissory note, and the remainder in cash ($4.5 million) and other deferred consideration. In January 2021, we agreed to extend the payment terms on the remaining outstanding working capital balance of $18.4 million. Accell had agreed to make monthly payments including interest through September 2022, under which we received full payments for January through March and partial payments in April and May (totaling $3.8 million including $0.7 million in interest). Based on Accell's failure to make timely payments, continued requests to defer payments significantly beyond the original maturity of the working capital note and the unfavorable impact of the COVID-19 pandemic on the Latin American markets, we determined to fully reserve the working capital and other deferred receivables, recognizing a loss on sale of business of $26.8 million for the year ended December 31, 2021. All receivables from Accell were fully written off in the fourth quarter of 2023.
