respectively. For the years ended December\u00a031, 2024, 2023 and 2022, the Company's amortization expense related to computer software was $155 million, $168 million and $166 million, respectively. Aircraft, spare engines and related rotable parts were assumed to have residual values of approximately 10% of original cost, and other categories of property and equipment were assumed to have no residual value.</span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%\">Leases. </span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">The Company enters into various leases as a lessee for assets including, but not limited to, airport facilities, airport gates, hanger sites, administrative offices, aircraft, and various other facilities and equipment to support its operations. The Company determines if an arrangement contains a lease at inception. A lease exists when the arrangement conveys the right to control the use of an identified asset over the lease term. Upon lease commencement, the Company records a lease liability for the obligation to make lease payments and right-of-use (\"ROU\") asset for the right to use the underlying asset for the lease term in the consolidated balance sheets. The lease liability is measured at the commencement date based on the present value of lease payments not yet paid over the lease term, which includes extension and renewal options that are reasonably certain of being exercised, discounted using an incremental borrowing rate that reflects the term of the lease and the particular economic environment at lease commencement. The ROU asset is based on the lease liability, adjusted for lease prepayments, lease incentives received, and the lessee's initial direct costs. The Company does not record a right-of-use asset or lease liability for leases with an initial term of 12 months or less. Lease and non-lease components are combined for all classes of underlying assets, except for capacity purchase agreements (\"CPAs\") which contain embedded leases for regional aircraft. For these CPAs, the Company allocates consideration to the lease and non-lease components based on their relative standalone values. Many of the Company's leases include variable lease payments, which are not included in the measurement of the right-of-use asset and lease liability. Finance lease right-of-use assets are presented together with Operating property and equipment on the consolidated balance sheets and the related amortization is included in Depreciation and amortization expense.</span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%\">Long-Lived Asset Impairments.</span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%\"> </span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">The Company evaluates the carrying value of long-lived assets subject to amortization whenever events or changes in circumstances indicate that an impairment may exist. For purposes of this testing, the Company has generally identified the aircraft fleet type as the lowest level of identifiable cash flows for its mainline fleet and the contract level for its regional fleet under CPAs. An impairment charge is recognized when the asset's carrying value exceeds its net undiscounted future cash flows. The amount of the charge is the difference between the asset's carrying value and fair market value.</span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%\">Intangible Assets.</span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%\"> </span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">The Company has finite-lived and indefinite-lived intangible assets, including goodwill. Finite-lived intangible assets are amortized over their estimated useful lives. Goodwill and indefinite-lived intangible assets are not amortized but are assessed for impairment on an annual basis as of October\u00a01, or more frequently if events or circumstances indicate that the asset may be impaired. The Company typically determines fair value using either market or a variation of the income approach valuation techniques. These measurements include the following key assumptions: (1) forecasted revenues, expenses, margin and cash flows, (2) terminal period growth rate, (3) an estimated weighted average cost of capital, (4) asset-specific risk factor and (5) a tax rate. These assumptions are consistent with those that hypothetical market participants would use. We recognize an impairment when the fair value of an intangible asset is less than its carrying value. </span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">For the Company's China route authority, the Company performed a quantitative assessment which involved determining the fair value of the asset and comparing that amount to the asset's carrying value. For all other intangible assets, the Company performed a qualitative assessment of whether it was more likely than not that an impairment had occurred. To determine fair value of the China route authority, the Company used a discounted cash flow method. Key assumptions used in the valuation model included forecasted revenues, margin and an overall discount rate. These assumptions are inherently uncertain as they relate to future events and circumstances.</span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times

limited to, airport facilities, airport gates, hanger sites, administrative offices, aircraft, and various other facilities and equipment to support its operations. The Company determines if an arrangement contains a lease at inception. A lease exists when the arrangement conveys the right to control the use of an identified asset over the lease term. Upon lease commencement, the Company records a lease liability for the obligation to make lease payments and right-of-use (\"ROU\") asset for the right to use the underlying asset for the lease term in the consolidated balance sheets. The lease liability is measured at the commencement date based on the present value of lease payments not yet paid over the lease term, which includes extension and renewal options that are reasonably certain of being exercised, discounted using an incremental borrowing rate that reflects the term of the lease and the particular economic environment at lease commencement. The ROU asset is based on the lease liability, adjusted for lease prepayments, lease incentives received, and the lessee's initial direct costs. The Company does not record a right-of-use asset or lease liability for leases with an initial term of 12 months or less. Lease and non-lease components are combined for all classes of underlying assets, except for capacity purchase agreements (\"CPAs\") which contain embedded leases for regional aircraft. For these CPAs, the Company allocates consideration to the lease and non-lease components based on their relative standalone values. Many of the Company's leases include variable lease payments, which are not included in the measurement of the right-of-use asset and lease liability. Finance lease right-of-use assets are presented together with Operating property and equipment on the consolidated balance sheets and the related amortization is included in Depreciation and amortization expense.</span></div>","language":"en-us"}]},{"name":"rpt:f-807","factDimensions":{"xbrl:concept":"us-gaap:ImpairmentOrDisposalOfLongLivedAssetsPolicyTextBlock","xbrl:period":"2024-01-01T00:00:00/2025-01-01T00:00:00","xbrl:entity":"cik:0000100517","xbrl:language":"en-us"},"factValues":[{"value":"<div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%\">Long-Lived Asset Impairments.</span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%\"> </span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">The Company evaluates the carrying value of long-lived assets subject to amortization whenever events or changes in circumstances indicate that an impairment may exist.

The Company typically determines fair value using either market or a variation of the income approach valuation techniques. These measurements include the following key assumptions: (1) forecasted revenues, expenses, margin and cash flows, (2) terminal period growth rate, (3) an estimated weighted average cost of capital, (4) asset-specific risk factor and (5) a tax rate.

To determine fair value of the China route authority, the Company used a discounted cash flow method.

The total consideration from each ticket sale is then allocated to each of these elements, individually, on a pro-rata basis.

The equivalent ticket value is based on the prior 12 months' weighted average equivalent ticket value of similar fares as those used to settle award redemptions while taking into consideration such factors as redemption pattern, cabin class, loyalty status and geographic region.

Accordingly, we determine our best estimate of selling price by considering multiple inputs and methods including, but not limited to, discounted cash flows, brand value, volume discounts, published selling prices, number of miles awarded and number of miles redeemed.

Tickets sold by other airlines where the Company provides the transportation are recognized as passenger revenue at the estimated value to be billed to the other airline when travel is provided. Differences between amounts billed and the actual amounts may be rejected and rebilled or written off if the amount recorded was different from the original estimate.

The time-vested RSUs vest pro-rata, a majority of which vest on February 28th of each year, over a three-year period from the date of grant. Performance-based awards vest either pro-rata, one-third each year, over a three-year period from the date of grant or all at once upon continuous employment with the Company over a three-year period. Payout under the performance-based awards can range from 0% to 300% depending on the achievement level of certain financial and strategic goals. RSUs are generally equity awards settled in stock for domestic employees and liability awards settled in cash for international employees. The cash payments are based on the 20-day average closing price of UAL common stock immediately prior to the vesting date. </span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span

Under these CPAs, the Company pays the regional carriers contractually agreed fees (carrier costs) for operating these flights plus a variable rate adjustment based on agreed performance metrics, subject to annual adjustments. The fees are based on specific rates multiplied by specific operating statistics (e.g.,\u00a0block hours, departures), as well as fixed monthly amounts. Under these CPAs, the Company is also responsible for all fuel costs incurred, as well as landing fees and other costs, which are either passed through by the regional carrier to the Company without any markup or directly incurred by the Company. In some cases, the Company owns some or all of the aircraft subject to the CPA and leases such aircraft to the regional carrier. United's CPAs are for 412 regional aircraft as of December 31, 2024, and the CPAs have terms expiring through 2036. Aircraft operated under CPAs include aircraft leased directly from the regional carriers and those owned by United and operated by the regional carriers.</span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">United recorded approximately $1.1 billion, $1.1 billion and $0.9 billion in expenses related to its CPAs with its regional carriers in which United is a minority shareholder, for the years ended December 31, 2024, 2023 and 2022, respectively.

At December 31, 2024, the Company had $8.5 billion of floating rate debt with remaining terms of up to approximately 12 years that are subject to these increased cost provisions.\u00a0In several financing transactions involving loans from non-U.S. entities, with remaining terms of up to approximately 12 years and an aggregate balance of $5.3 billion, the Company bears the risk of any change in tax laws that would subject loan payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.</span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%\">Fuel Consortia. </span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">United participates in numerous fuel consortia with other air carriers at major airports to reduce the costs of fuel distribution and storage. Interline agreements govern the rights and responsibilities of the consortia members and provide for the allocation of the overall costs to operate the consortia based on usage. The consortia (and in limited cases, the participating carriers) have entered into long-term agreements to lease certain airport fuel storage and distribution facilities that are typically financed through various debt obligations. In general, each consortium lease agreement requires the consortium to make lease payments in amounts sufficient to pay the maturing principal and interest payments on these debt obligations. As of December 31, 2024, approximately $2.7 billion principal amount of such loans was secured by significant fuel facility leases in which United participates, as to which United and each of the signatory airlines has provided indirect guarantees of the debt. As of December 31, 2024, the Company's contingent exposure was approximately $504 million principal amount of such obligations based on its recent consortia participation. The Company's contingent exposure could increase if the participation of other air carriers decreases. The guarantees will expire when these obligations are paid in full, which ranges from 2027 to 2056. The Company concluded it was not necessary to record a liability for these indirect guarantees.</span></div><div style=\"margin-bottom:5pt;margin-top:9pt\"><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%\">Credit Card Processing Agreements. </span><span style=\"color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%\">The Company has agreements with financial institutions that process customer credit card transactions for the sale of air travel and other services.
