(1)Represents impairment charges resulting from the Company’s regular analysis of whether the anticipated future cash flows from certain towers are sufficient to recover the carrying value of the investment in those towers. Impairment charges for the year ended December 31, 2023 includes the impact of the planned abandonment of identified sites with minimal expectations of future economic benefit (primarily from Sprint and Oi related churn), partially offset by a $45.1 million benefit from the reassessment of the lease terms. The reassessment resulted in an overall shortening of the lease term and a reduction to the lease liability and right-of-use asset.
