Our depreciation expense was $20,421 in 2024, $18,593 in 2023, and $17,852 in 2022. Depreciation expense included amortization of software totaling $3,076 in 2024, $3,023 in 2023 and $2,972 in 2022.

In December 2022, we recorded a noncash pre-tax charge of $1,413 to abandon conduits that will not be utilized to support future network activity. The abandonment was considered outside the ordinary course of business.

During the first quarter of 2022, we updated our analysis of economic lives of AT&T-owned fiber network assets. As of January 1, 2022, we extended the estimated economic life and depreciation period of such costs to better reflect the physical life of the assets that we had been experiencing and absence of technological changes that would replace fiber as the best broadband technology in the industry. The change in accounting estimate decreased depreciation expense $280, or $0.03 per diluted share from continuing operations for the year ended December 31, 2022.
