Impairment	ImpairmentLong-lived Assets Accounting Standards Codification (ASC) 360 - Property, Plant, and Equipment (ASC 360) requires long-lived assets to be assessed for impairment when events and circumstances indicate that the assets may be impaired. Long-lived assets consist of owned flight and ground equipment, ROU assets and definite-lived intangible assets such as certain domestic airport slots and gate leasehold rights, customer relationships and marketing agreements. As previously discussed, in the first nine months of 2020, our operations, liquidity and stock price were significantly impacted by decreased passenger demand and government travel restrictions due to COVID-19. Additionally, we decided to retire certain mainline aircraft earlier than planned including Airbus A330-200, Boeing 757, Boeing 767, Airbus A330-300 and Embraer 190 aircraft as well as regional aircraft, including certain Embraer 140 and Bombardier CRJ200 aircraft. As a result of these events and circumstances, in each of the first three quarters of 2020, we performed impairment tests on our long-lived assets in connection with the preparation of our financial statements. In accordance with ASC 360, an impairment of a long-lived asset or group of long-lived assets exists only when the sum of the estimated undiscounted future cash flows expected to be generated directly by the assets are less than the carrying value of the assets. We group assets principally by fleet-type when estimating future cash flows, which is generally the lowest level for which identifiable cash flows exist. Estimates of future cash flows are based on historical results adjusted to reflect management’s best estimate of future market and operating conditions, including our current fleet plan. As a result of the impairment tests performed on our long-lived assets, we determined the sum of the estimated undiscounted future cash flows exceeded the $42.0 billion carrying value for our long-lived assets except for the aircraft being retired earlier than planned as discussed above. For those aircraft and certain related spare parts, we recorded impairment charges reflecting the difference between the carrying values of these assets and their fair values of $714 million and $1.5 billion for the three and nine months ended September 30, 2020, respectively. Fair value reflects management’s best estimate including inputs from published pricing guides and bids from third parties as well as contracted sales agreements when applicable. Due to the inherent uncertainties of the current operating environment, we will continue to evaluate our current fleet (including aircraft in temporary storage) and may decide to permanently retire additional aircraft. Goodwill and Indefinite-lived Intangible Assets ASC 350 - Intangibles - Goodwill and Other (ASC 350) requires goodwill and indefinite-lived intangible assets to be assessed for impairment annually or more frequently if events or circumstances indicate that the fair values of goodwill and indefinite-lived intangible assets may be lower than their carrying values. Goodwill represents the purchase price in excess of the fair value of the net assets acquired and liabilities assumed in connection with the merger with US Airways Group, Inc. We have one reporting unit. Indefinite-lived intangible assets consist of certain domestic airport slots and international slots and route authorities. In each of the first three quarters of 2020, we performed interim impairment tests on our goodwill and indefinite-lived intangible assets as a result of the events and circumstances previously discussed due to the impact of COVID-19 on our business. In accordance with ASC 350, for goodwill, we performed a quantitative analysis by using a market approach. Under the market approach, the fair value of the reporting unit was determined based on quoted market prices for equity and the fair value of debt as described in Note 8. The fair value exceeded the carrying value of the reporting unit, and our $4.1 billion of goodwill was not impaired. Additionally, we performed interim qualitative impairment tests on our $1.8 billion of indefinite-lived intangible assets and determined there was no material impairment. As discussed above, due to the inherent uncertainties of the current operating environment, we will continue to evaluate our goodwill and indefinite-lived intangible assets for events or circumstances that indicate that their fair values may be lower than their carrying values.
