Gains and losses on the retirement of assets are included in operating income. Long -livedassets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets that are held and used is measured by net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying value exceeds the fair value of the assets, which is based on a discounted cash flow model. As of December 31, 2024 and 2023, no assets were impaired. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.
