Other Operating Income (Expense), Net Other operating income (expense), net, is comprised generally of gains and losses on divestitures and the sale of assets; asset and portfolio rationalization charges; recoveries and losses related to certain customer accounts receivable; rental, royalty and services income; and accretion expense, depreciation expense and gains and losses related to asset retirement obligations. For the three months ended March 31, 2024, other operating (income) expense, net, included a $1.3 billion pretax gain on the divestiture of the South Texas cement business and certain of its related ready mixed concrete operations, which was partially offset by a $49 million pretax, noncash asset and portfolio rationalization charge. The noncash asset and portfolio rationalization charge for the three months ended March 31, 2024 relates to the Company's decision to cease using a railroad to transport aggregates products into Colorado. In connection with the AFS acquisition completed in January 2024, the Company has more local supply available from its operations and has discontinued using the railroad. This charge, which is reported in the West Group, reflects the Company's evaluation of the recoverability of certain long-lived assets, including property, plant and equipment and operating lease right-of-use assets, for the cessation of these railroad operations.

Other Operating Income (Expense), Net

Other operating income (expense), net, is comprised generally of gains and losses on divestitures and the sale of assets; asset and portfolio rationalization charges; recoveries and losses related to certain customer accounts receivable; rental, royalty and services income; and accretion expense, depreciation expense and gains and losses related to asset retirement obligations. For the three months ended March 31, 2024, other operating (income) expense, net, included a $1.3 billion pretax gain on the divestiture of the South Texas cement business and certain of its related ready mixed concrete operations, which was partially offset by a $49 million pretax, noncash asset and portfolio rationalization charge.

The noncash asset and portfolio rationalization charge for the three months ended March 31, 2024 relates to the Company's decision to cease using a railroad to transport aggregates products into Colorado. In connection with the AFS acquisition completed in January 2024, the Company has more local supply available from its operations and has discontinued using the railroad. This charge, which is reported in the West Group, reflects the Company's evaluation of the recoverability of certain long-lived assets, including property, plant and equipment and operating lease right-of-use assets, for the cessation of these railroad operations.
