 be added to the acquired towers (referred to as the “Network location intangibles”). These intangibles are estimated to have a useful life consistent with the useful life of the related tower assets, which is typically 30 years. For all intangible assets, amortization is provided using the straight-line method over the estimated useful lives as the benefit associated with these intangible assets is anticipated to be derived evenly over the life of the asset. Impairment of Long-Lived AssetsThe Company evaluates its individual long-lived and related assets with finite lives for indicators of impairment to determine when an impairment analysis should be performed. The Company evaluates its tower and related assets at the tower level, which is the lowest level for which identifiable cash flows exists. The Company evaluates its Network location intangibles for impairment at the tower leasing business level. The Company has established a policy to at least annually, or earlier if indicators of impairment arise, evaluate its tower assets and Current contract and Network location intangibles for impairment.The Company performs its evaluation for impairment by first calculating the future undiscounted cash flows of its investments in towers and related assets and comparing those amounts to the carrying value of the assets. If the future undiscounted cash flows are lower than the carrying value of the investment in the tower and related assets, the Company calculates the future discounted cash flows and compares those amounts to the carrying value. The Company records an impairment charge for any amounts lower than the carrying value. Estimates and assumptions inherent in the impairment evaluation include, but are not limited to, general market and economic conditions, historical operating results, geographic location, lease-up potential, and expected timing of lease-up. In addition, the Company makes certain assumptions in determining an asset’s fair value for the purpose of calculating the amount of an impairment charge.The Company recognized impairment charges of $107.9 million, $169.4 million, and $43.2 million for the years ended December 31, 2024, 2023 and 2022, respectively. Refer to Note 3 for further detail of these amounts.‎

 Fair Value MeasurementsThe Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following three levels of inputs may be used to measure fair value:      Level 1Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the
