Basis of Presentation and Summary of Significant Accounting Policies	1. Basis of Presentation and Summary of Significant Accounting Policies (a) Basis of Presentation American Airlines Group Inc. (we, us, our and similar terms, or AAG), a Delaware corporation, is a holding company whose primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo through its mainline operating subsidiary, American Airlines, Inc. (American) and its wholly-owned regional airline subsidiaries, Envoy Aviation Group Inc. (Envoy), Piedmont Airlines, Inc. (Piedmont) and PSA Airlines, Inc. (PSA) that operate under capacity purchase agreements as American Eagle. On December 9, 2013, a subsidiary of AMR merged with and into US Airways Group, Inc. (US Airways Group), a Delaware corporation, which survived as a wholly-owned subsidiary of AAG, and AAG emerged from Chapter 11 (the Merger). Upon closing of the Merger and emergence from Chapter 11, AMR changed its name to American Airlines Group Inc. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, valuation allowance for deferred tax assets, as well as pensions and retiree medical and other postretirement benefits. Certain prior year amounts have been reclassified to conform to the current year presentation. (b) Short-term Investments Short-term investments are classified as available-for-sale (c) Restricted Cash and Short-term Investments We have restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations. (d) Aircraft Fuel, Spare Parts, and Supplies, Net Aircraft fuel is recorded on a first-in, first-out (e) Operating Property and Equipment Operating property and equipment is recorded at cost and depreciated or amortized to residual values over the asset’s estimated useful life or the lease term, whichever is less, using the straight-line method. Residual values for aircraft, engines, and related rotable parts are generally 5% to 10% of original cost. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated or amortized over the estimated useful life of the asset or the lease term, whichever is less. The estimated useful lives for the principal property and equipment classifications are as follows: Principal Property and Equipment Classification Estimated Useful Life Aircraft, engines and related rotable parts 20 – 30 years Buildings and improvements Lesser of 5 – 30 years Furniture, fixtures and other equipment 3 – 10 years Capitalized software 5 – 10 years We record impairment charges on operating property and equipment when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the assets are less than the carrying amount of the assets and the net book value of the assets exceeds their estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell. (f) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes. We provide a valuation allowance for our deferred tax assets when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our projections of future profitability, including risks associated with remaining Merger integration activities as well as other conditions which are beyond our control, such as the health of the economy, the level and volatility of fuel prices and travel demand. (g) Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired and liabilities assumed. Goodwill is not amortized but assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that goodwill may be impaired. We have one consolidated reporting unit. Goodwill is measured for impairment by initially performing a qualitative assessment and, if necessary, then comparing the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is less than the carrying value, a second step is performed to determine the implied fair value of goodwill. If the implied fair value of goodwill is lower than its carrying value, an impairment charge equal to the difference is recorded. Based upon our annual assessment, there was no goodwill impairment in 2016. The carrying value of the goodwill on our consolidated balance sheets was $4.1 billion as of December 31, 2016 and 2015. (h) Other Intangibles, Net Intangible assets consist primarily of domestic airport slots, customer relationships, marketing agreements, international slots and route authorities, airport gate leasehold rights and tradenames. Finite-Lived Intangible Assets Finite-lived intangible assets are amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The following table provides information relating to our amortizable intangible assets as of December 31, 2016 and 2015 (in millions): December 31, 2016 2015 Domestic airport slots $ 365 $ 365 Customer relationships 300 300 Marketing agreements 105 105 Tradenames 35 35 Airport gate leasehold rights 137 137 Accumulated amortization (578 ) (502 ) Total $ 364 $ 440 Certain domestic airport slots and airport gate leasehold rights are amortized on a straight-line basis over 25 years. The customer relationships and marketing agreements were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately nine years and 30 years, respectively. Tradenames are fully amortized. We recorded amortization expense related to these intangible assets of $76 million, $55 million and $81 million for the years ended December 31, 2016, 2015 and 2014, respectively. We expect to record annual amortization expense for these intangible assets as follows (in millions): 2017 $ 45 2018 41 2019 41 2020 41 2021 41 2022 and thereafter 155 Total $ 364 Indefinite-Lived Intangible Assets Indefinite-lived intangible assets include certain domestic airport slots at our hubs and international slots and route authorities. Indefinite-lived intangible assets are not amortized but instead are assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2016 and 2015, we had $1.8 billion of indefinite-lived intangible assets on our consolidated balance sheets. Indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative assessment to determine whether we believe it is more likely than not that an asset has been impaired. If we believe impairment has occurred, we then evaluate for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon our annual assessment, there was no indefinite-lived intangible asset impairment in 2016. (i) Loyalty Program We currently operate the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any one co-branded We use the incremental cost method to account for the portion of our loyalty program liability incurred when AAdvantage members earn mileage credits by flying on American, any one The incremental cost liability includes all mileage credits, even mileage credits for members whose account balances have not yet reached the minimum level required to redeem an award. Mileage credits are subject to expiration. The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. The estimated incremental cost primarily includes unit costs incurred for fuel, food and insurance as well as fees incurred when travel awards are redeemed on partner airlines. In calculating the liability, we estimate how many mileage credits will never be redeemed for travel and exclude those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These costs and estimates are based on our historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the consolidated statements of operations as a part of passenger revenue. As of December 31, 2016 and 2015, the liability for outstanding mileage credits accounted for under the incremental cost method was $669 million and $657 million, respectively, and is included on the consolidated balance sheets within loyalty program liability. Additionally, we applied the acquisition method of accounting in connection with the Merger in December 2013 and recorded a liability for outstanding US Airways’ mileage credits at fair value, an amount significantly in excess of incremental cost. At December 31, 2016, all the mileage credits associated with this liability have been recognized in passenger revenue. At December 31, 2015, this liability was $296 million and was included on the consolidated balance sheet within the loyalty program liability. We also sell loyalty program mileage credits to participating airline partners and non-airline non-airline non-airline No. 2009-13, In 2016, American entered into new co-branded co-branded The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and is amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel. As of December 31, 2016 and 2015, we had $2.1 billion and $1.5 billion, respectively, in deferred revenue from the sale of mileage credits recorded within loyalty program liability on our consolidated balance sheets. The services under the marketing component are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale. For the years ended December 31, 2016, 2015 and 2014, the marketing component of mileage sales and other marketing related payments included in other revenues was approximately $1.9 billion, $1.7 billion and $1.6 billion, respectively. (j) Revenue Passenger Revenue Passenger revenue is recognized when transportation is provided. Ticket sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on the consolidated balance sheets. The air traffic liability represents tickets sold for future travel dates and estimated future refunds and exchanges of tickets sold for past travel dates. The balance in the air traffic liability fluctuates throughout the year based on seasonal travel patterns and fare sale activity. Our air traffic liability was $3.9 billion and $3.7 billion as of December 31, 2016 and 2015, respectively. The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. Due to complex pricing structures, refund and exchange policies, and interline agreements with other airlines, certain amounts are recognized in passenger revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized. These estimates are generally based on the analysis of our historical data. We and other airline industry participants have consistently applied this accounting method to estimate revenue from forfeited tickets at the date of travel. Estimated future refunds and exchanges included in the air traffic liability are routinely evaluated based on subsequent activity to validate the accuracy of our estimates. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed. We have arrangements with regional carriers to provide us with regional jet and turboprop service under the brand name “American Eagle.” The American Eagle carriers include our wholly-owned regional carriers, Envoy, PSA and Piedmont, as well as third-party regional carriers including Republic Airline Inc. (Republic), Mesa Airlines, Inc. (Mesa), Air Wisconsin Airlines Corporation (Air Wisconsin), Compass Airlines, LLC (Compass), ExpressJet Airlines, Inc. (ExpressJet), SkyWest Airlines, Inc. (SkyWest) and Trans States Airlines, Inc. (Trans States). We classify revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by us for travel on these air carriers is also included in our air traffic liability and are subsequently recognized as revenue in the same manner as described above. Passenger Taxes and Fees Various taxes and fees assessed on the sale of tickets to end customers are collected by us as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority. Cargo Revenue Cargo revenue is recognized when we provide the transportation. Other Revenue Other revenue includes revenue associated with marketing services provided to our business partners as part of our loyalty program, baggage fees, ticketing change fees, airport clubs and inflight services. The accounting and recognition for the loyalty program marketing services are discussed in Note 1(i) above. Baggage fees, ticketing change fees, airport clubs and inflight service revenues are recognized when we provide the service. (k) Maintenance, Materials and Repairs Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists. (l) Selling Expenses Selling expenses include credit card fees, commissions, computerized reservations systems fees and advertising. Advertising costs are expensed as incurred. Advertising expense was $116 million, $110 million and $92 million for the years ended December 31, 2016, 2015 and 2014, respectively. (m) Share-based Compensation We account for our share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The fair value of stock options and stock appreciation rights (SARs) is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units (RSUs) is based on the market price of the underlying shares of common stock on the date of grant. See Note 14 for further discussion of share-based compensation. (n) Deferred Gains and Credits, Net Included within deferred gains and credits, net are amounts deferred and amortized into future periods associated with the adjustment of leases to fair value in connection with the application of acquisition accounting, deferred gains on the sale-leaseback of aircraft and certain vendor incentives. We periodically receive vendor incentives in connection with acquisition of aircraft and engines. These credits are deferred until aircraft and engines are delivered and then applied as a reduction to the cost of the related equipment. (o) Foreign Currency Gains and Losses Foreign currency gains and losses are recorded as part of other nonoperating expense, net in our consolidated statements of operations. Foreign currency gains for 2016 were $1 million. Foreign currency losses for 2015 and 2014 were $751 million and $114 million, respectively. Included in 2015 was a $592 million nonoperating special charge to write off all of the value of Venezuelan bolivars held by us due to continued lack of repatriations and deterioration of economic conditions in Venezuela. (p) Other Operating Expenses Other operating expenses includes costs associated with ground and cargo handling, crew travel, aircraft food and catering, passenger accommodation, airport security, international navigation fees and certain general and administrative expenses. (q) Regional Expenses Expenses associated with our wholly-owned regional airlines and third-party regional carriers operating under the brand name American Eagle are classified as regional expenses on the consolidated statements of operations. Regional expenses consist of the following (in millions): Year Ended December 31, 2016 2015 2014 Aircraft fuel and related taxes $ 1,109 $ 1,230 $ 2,009 Salaries, wages and benefits 1,333 1,187 1,140 Capacity purchases from third-party regional carriers (1) 1,538 1,651 1,494 Maintenance, materials and repairs 345 323 367 Other rent and landing fees 564 504 444 Aircraft rent 36 34 35 Selling expenses 347 333 307 Depreciation and amortization 301 252 217 Special items, net 14 29 24 Other 457 440 479 Total regional expenses $ 6,044 $ 5,983 $ 6,516 (1) For the years ended December 31, 2016, 2015 and 2014, the component of capacity purchase expenses related to aircraft deemed to be leased was approximately $405 million, $492 million and $447 million, respectively. (r) Recent Accounting Pronouncements Revenue In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, 2014-09 We are still in the process of evaluating how the adoption of the new revenue standard will impact our consolidated financial statements. We currently expect that the new revenue standard will materially impact our liability for outstanding mileage credits earned by AAdvantage loyalty program members when flying on American. We currently use the incremental cost method to account for this portion of our loyalty program liability, which values these mileage credits based on the estimated incremental cost of carrying one additional passenger (see (i) Loyalty Program above). The new revenue standard will require us to change our policy and apply a relative selling price approach whereby a portion of each passenger ticket sale attributable to mileage credits earned will be deferred and recognized in passenger revenue upon future mileage redemption. The carrying value of the earned mileage credits recognized in loyalty program liability is expected to be materially greater under the relative selling price approach than the value attributed to these mileage credits under the incremental cost method. The new revenue standard will also require us to reclassify certain ancillary fees to passenger revenue, which are currently included within other operating revenue.

American Airlines, Inc. [Member]
Basis of Presentation and Summary of Significant Accounting Policies	1. Basis of Presentation and Summary of Significant Accounting Policies (a) Basis of Presentation American Airlines, Inc. (American) is a Delaware corporation whose primary business activity is the operation of a major network air carrier. American is a wholly-owned subsidiary of American Airlines Group Inc. (AAG), which owns all of American’s outstanding common stock, par value $1.00 per share. On December 9, 2013, a subsidiary of AMR merged with and into US Airways Group, Inc. (US Airways Group), a Delaware corporation, which survived as a wholly-owned subsidiary of AAG, and AAG emerged from Chapter 11 (the Merger). Upon closing of the Merger and emergence from Chapter 11, AMR changed its name to American Airlines Group Inc. On December 30, 2015, in order to simplify AAG’s internal corporate structure, US Airways, Inc. (US Airways), a wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, valuation allowance for deferred tax assets, as well as pensions and retiree medical and other postretirement benefits. Certain prior year amounts have been reclassified to conform to the current year presentation. (b) Short-term Investments Short-term investments are classified as available-for-sale (c) Restricted Cash and Short-term Investments American has restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations. (d) Aircraft Fuel, Spare Parts, and Supplies, Net Aircraft fuel is recorded on a first-in, first-out (e) Operating Property and Equipment Operating property and equipment is recorded at cost and depreciated or amortized to residual values over the asset’s estimated useful life or the lease term, whichever is less, using the straight-line method. Residual values for aircraft, engines, and related rotable parts are generally 5% to 10% of original cost. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated or amortized over the estimated useful life of the asset or the lease term, whichever is less. The estimated useful lives for the principal property and equipment classifications are as follows: Principal Property and Equipment Classification Estimated Useful Life Aircraft, engines and related rotable parts 20 – 30 years Buildings and improvements Lesser of 5 - 30 years Furniture, fixtures and other equipment 3 - 10 years Capitalized software 5 - 10 years American records impairment charges on operating property and equipment when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the assets are less than the carrying amount of the assets and the net book value of the assets exceeds their estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell. (f) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes. American provides a valuation allowance for its deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. American considers all available positive and negative evidence and makes certain assumptions in evaluating the realizability of its deferred tax assets. Many factors are considered that impact American’s projections of future profitability, including risks associated with remaining Merger integration activities as well as other conditions which are beyond American’s control, such as the health of the economy, the level and volatility of fuel prices and travel demand. (g) Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired and liabilities assumed. Goodwill is not amortized but assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that goodwill may be impaired. American has one consolidated reporting unit. Goodwill is measured for impairment by initially performing a qualitative assessment and, if necessary, then comparing the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is less than the carrying value, a second step is performed to determine the implied fair value of goodwill. If the implied fair value of goodwill is lower than its carrying value, an impairment charge equal to the difference is recorded. Based upon American’s annual assessment, there was no goodwill impairment in 2016. The carrying value of the goodwill on American’s consolidated balance sheets was $4.1 billion as of December 31, 2016 and 2015. (h) Other Intangibles, Net Intangible assets consist primarily of domestic airport slots, customer relationships, marketing agreements, international slots and route authorities, airport gate leasehold rights and tradenames. Finite-Lived Intangible Assets Finite-lived intangible assets are amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The following table provides information relating to American’s amortizable intangible assets as of December 31, 2016 and 2015 (in millions): December 31, 2016 2015 Domestic airport slots $ 365 $ 365 Customer relationships 300 300 Marketing agreements 105 105 Tradenames 35 35 Airport gate leasehold rights 137 137 Accumulated amortization (578 ) (502 ) Total $ 364 $ 440 Certain domestic airport slots and airport gate leasehold rights are amortized on a straight-line basis over 25 years. The customer relationships and marketing agreements were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately nine years and 30 years, respectively. Tradenames are fully amortized. American recorded amortization expense related to these intangible assets of $76 million, $55 million and $81 million for the years ended December 31, 2016, 2015 and 2014, respectively. American expects to record annual amortization expense for these intangible assets as follows (in millions): 2017 $ 45 2018 41 2019 41 2020 41 2021 41 2022 and thereafter 155 Total $ 364 Indefinite-Lived Intangible Assets Indefinite-lived intangible assets include certain domestic airport slots at American’s hubs and international slots and route authorities. Indefinite-lived intangible assets are not amortized but instead are assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2016 and 2015, American had $1.8 billion of indefinite-lived intangible assets on its consolidated balance sheets. Indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative assessment to determine whether American believes it is more likely than not that an asset has been impaired. If American believes impairment has occurred, American then evaluates for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon American’s annual assessment, there was no indefinite-lived intangible asset impairment in 2016. (i) Loyalty Program American currently operates the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any one co-branded American uses the incremental cost method to account for the portion of its loyalty program liability incurred when AAdvantage members earn mileage credits by flying on American, any one The incremental cost liability includes all mileage credits, even mileage credits for members whose account balances have not yet reached the minimum level required to redeem an award. Mileage credits are subject to expiration. The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. The estimated incremental cost primarily includes unit costs incurred for fuel, food and insurance as well as fees incurred when travel awards are redeemed on partner airlines. In calculating the liability, American estimates how many mileage credits will never be redeemed for travel and excludes those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These costs and estimates are based on American’s historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the consolidated statements of operations as a part of passenger revenue. As of December 31, 2016 and 2015, the liability for outstanding mileage credits accounted for under the incremental cost method was $669 million and $657 million, respectively, and is included on the consolidated balance sheets within loyalty program liability. Additionally, American applied the acquisition method of accounting in connection with AAG’s Merger in December 2013 and recorded a liability for outstanding US Airways’ mileage credits at fair value, an amount significantly in excess of incremental cost. At December 31, 2016, all the mileage credits associated with this liability have been recognized in passenger revenue. At December 31, 2015, this liability was $296 million and was included on the consolidated balance sheet within the loyalty program liability. American also sells loyalty program mileage credits to participating airline partners and non-airline non-airline non-airline No. 2009-13, In 2016, American entered into new co-branded co-branded The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and is amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel. As of December 31, 2016 and 2015, American had $2.1 billion and $1.5 billion, respectively, in deferred revenue from the sale of mileage credits recorded within loyalty program liability on its consolidated balance sheets. The services under the marketing component are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale. For the years ended December 31, 2016, 2015 and 2014, the marketing component of mileage sales and other marketing related payments included in other revenues was approximately $1.9 billion, $1.7 billion and $1.6 billion, respectively. (j) Revenue Passenger Revenue Passenger revenue is recognized when transportation is provided. Ticket sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on the consolidated balance sheets. The air traffic liability represents tickets sold for future travel dates and estimated future refunds and exchanges of tickets sold for past travel dates. The balance in the air traffic liability fluctuates throughout the year based on seasonal travel patterns and fare sale activity. American’s air traffic liability was $3.9 billion and $3.7 billion as of December 31, 2016 and 2015, respectively. The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. Due to complex pricing structures, refund and exchange policies, and interline agreements with other airlines, certain amounts are recognized in passenger revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized. These estimates are generally based on the analysis of American’s historical data. American and other airline industry participants have consistently applied this accounting method to estimate revenue from forfeited tickets at the date of travel. Estimated future refunds and exchanges included in the air traffic liability are routinely evaluated based on subsequent activity to validate the accuracy of American’s estimates. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed. American has arrangements with regional carriers to provide it with regional jet and turboprop service under the brand name “American Eagle.” The American Eagle carriers include AAG’s wholly-owned regional carriers, Envoy, PSA and Piedmont, as well as third-party regional carriers including Republic Airline Inc. (Republic), Mesa Airlines, Inc. (Mesa), Air Wisconsin Airlines Corporation (Air Wisconsin), Compass Airlines, LLC (Compass), ExpressJet Airlines, Inc. (ExpressJet), SkyWest Airlines, Inc. (SkyWest) and Trans States Airlines, Inc. (Trans States). American classifies revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by American for travel on these air carriers are also included in American’s air traffic liability and are subsequently recognized as revenue in the same manner as described above. Passenger Taxes and Fees Various taxes and fees assessed on the sale of tickets to end customers are collected by American as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority. Cargo Revenue Cargo revenue is recognized when American provides the transportation. Other Revenue Other revenue includes revenue associated with marketing services provided to American’s business partners as part of its loyalty program, baggage fees, ticketing change fees, airport clubs and inflight services. The accounting and recognition for the loyalty program marketing services are discussed in Note 1(i) above. Baggage fees, ticketing change fees, airport clubs and inflight service revenues are recognized when American provides the service. (k) Maintenance, Materials and Repairs Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists. (l) Selling Expenses Selling expenses include credit card fees, commissions, computerized reservations systems fees and advertising. Advertising costs are expensed as incurred. Advertising expense was $116 million, $110 million and $92 million for the years ended December 31, 2016, 2015 and 2014, respectively. (m) Share-based Compensation American accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The fair value of stock options and stock appreciation rights (SARs) is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units (RSUs) is based on the market price of the underlying shares of common stock on the date of grant. See Note 12 for further discussion of share-based compensation. (n) Deferred Gains and Credits, Net Included within deferred gains and credits, net are amounts deferred and amortized into future periods associated with the adjustment of leases to fair value in connection with the application of acquisition accounting, deferred gains on the sale-leaseback of aircraft and certain vendor incentives. American periodically receives vendor incentives in connection with acquisition of aircraft and engines. These credits are deferred until aircraft and engines are delivered and then applied as a reduction to the cost of the related equipment. (o) Foreign Currency Gains and Losses Foreign currency gains and losses are recorded as part of other nonoperating expense, net in American’s consolidated statements of operations. Foreign currency gains for 2016 were $1 million. Foreign currency losses for 2015 and 2014 were $751 million and $114 million, respectively. Included in 2015 was a $592 million nonoperating special charge to write off all of the value of Venezuelan bolivars held by American due to continued lack of repatriations and deterioration of economic conditions in Venezuela. (p) Other Operating Expenses Other operating expenses includes costs associated with ground and cargo handling, crew travel, aircraft food and catering, passenger accommodation, airport security, international navigation fees and certain general and administrative expenses. (q) Regional Expenses Expenses associated with American’s third-party regional carriers operating under the brand name American Eagle are classified as regional expenses on the consolidated statements of operations. Regional expenses consist of the following (in millions): Year Ended December 31, 2016 2015 2014 Aircraft fuel and related taxes $ 1,109 $ 1,230 $ 2,009 Salaries, wages and benefits 327 276 228 Capacity purchases from third-party regional carriers (1) 3,186 3,137 2,858 Maintenance, materials and repairs 4 4 6 Other rent and landing fees 487 434 386 Aircraft rent 28 28 27 Selling expenses 347 333 307 Depreciation and amortization 237 197 168 Special items, net 13 18 5 Other 271 295 483 Total regional expenses $ 6,009 $ 5,952 $ 6,477 (1) For the years ended December 31, 2016, 2015 and 2014, the component of capacity purchase expenses related to aircraft deemed to be leased was approximately $405 million, $492 million and $447 million, respectively. (r) Recent Accounting Pronouncements Revenue In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, 2014-09 American is still in the process of evaluating how the adoption of the new revenue standard will impact its consolidated financial statements. American currently expects that the new revenue standard will materially impact its liability for outstanding mileage credits earned by AAdvantage loyalty program members when flying on American. American currently uses the incremental cost method to account for this portion of its loyalty program liability, which values these mileage credits based on the estimated incremental cost of carrying one additional passenger (see (i) Loyalty Program above). The new revenue standard will require American to change its policy and apply a relative selling price approach whereby a portion of each passenger ticket sale attributable to mileage credits earned will be deferred and recognized in passenger revenue upon future mileage redemption. The carrying value of the earned mileage credits recognized in loyalty program liability is expected to be materially greater under the relative selling price approach than the value attributed to these mileage credits under the incremental cost method. The new revenue standard will also require American to reclassify certain ancillary fees to passenger revenue, which are currently included within other operating revenue.

Earnings Per Common Share The following table sets forth the computation of basic and diluted earnings per common share (EPS) (in millions, except share and per share amounts in thousands): Year Ended December 31, 2016 2015 2014 Basic EPS: Net income $ 2,676 $ 7,610 $ 2,882 Weighted average common shares outstanding (in thousands) 552,308 668,393 717,456 Basic EPS $ 4.85 $ 11.39 $ 4.02 Diluted EPS: Net income $ 2,676 $ 7,610 $ 2,882 Change in fair value of conversion feature on 7.25% convertible senior notes (a) — — 3 Net income for purposes of computing diluted EPS $ 2,676 $ 7,610 $ 2,885 Share computation for diluted EPS (in thousands): Basic weighted average common shares outstanding 552,308 668,393 717,456 Dilutive effect of stock awards 3,791 18,962 15,603 Assumed conversion of convertible senior notes — — 957 Diluted weighted average common shares outstanding 556,099 687,355 734,016 Diluted EPS $ 4.81 $ 11.07 $ 3.93 The following were excluded from the calculation of diluted EPS (in thousands): Stock options, SARs and RSUs because inclusion would be antidilutive 1,429 764 226 (a) In March 2014, we notified the holders of the 7.25% convertible senior notes that we had elected to settle all future conversions solely in cash instead of shares of AAG common stock in accordance with the related indenture. Thus, the diluted shares include the weighted average impact of the 7.25% convertible senior notes only for the period from January 1, 2014 to March 12, 2014. In addition, under GAAP, we must adjust the numerator for purposes of calculating diluted EPS by the change in fair value of the conversion feature from March 12, 2014 to May 15, 2014, which increased GAAP net income for purposes of computing diluted EPS by $3 million for the year ended December 31, 2014.

As of December 31, 2016, there were no borrowings or letters of credit outstanding under the 2013 or 2014 Revolving Facilities. The April 2016 and December 2016 Credit Facilities each provide for a revolving credit facility that may be established in the future. Subject to certain limitations and exceptions, the Credit Facilities are secured by certain collateral, including spare parts, certain slots, route authorities and airport gate leasehold rights. American has the ability to make future modifications to the collateral pledged, subject to certain restrictions. American’s obligations under the Credit Facilities are guaranteed by AAG. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans as further described below in “Collateral-Related Covenants.” The Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and become due and payable immediately. In addition, if a “change of control” occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the Credit Facilities and terminate the 2013 and 2014 Revolving Facilities and any revolving credit facilities established under the April 2016 or December 2016 Credit Facilities. The Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions. (b) 2013 Citicorp Credit Facility On May 23, 2013, American entered into a term loan credit facility (as amended, the 2013 Citicorp Credit Facility) with Citicorp North America, Inc., as administrative agent, and certain lenders.

Debt incurred under these loan agreements matures in 2021 through 2028 and bears interest at fixed and variable rates of LIBOR plus an applicable margin averaging 2.96% at December 31, 2016. (e) Special Facility Revenue Bonds 2016 Financing Activity In June 2016, the New York Transportation Development Corporation (NYTDC) issued approximately $844 million of special facility revenue refunding bonds (the 2016 JFK Bonds) on behalf of American. The net proceeds from the 2016 JFK Bonds generally were used to provide a portion of the funds to refinance $1.0 billion of special facility revenue bonds (Prior JFK Bonds), the net proceeds of which partially financed the construction of a terminal (the Terminal) used by American at John F. Kennedy International Airport (JFK). American is required to pay debt service on the 2016 JFK Bonds through payments under a loan agreement with NYTDC, and American and AAG guarantee the 2016 JFK Bonds. American’s and AAG’s obligations under these guarantees are secured by a mortgage on American’s lease of the Terminal and related property from the Port Authority of New York and New Jersey. The 2016 JFK Bonds, in aggregate, were priced at approximately 107% of par value. The gross proceeds from the issuance of the 2016 JFK Bonds were approximately $907 million. Of this amount, approximately $895 million was used to partially fund the redemption of the Prior JFK Bonds. The 2016 JFK Bonds bear interest at 5.0% per annum and are comprised of $212 million of serial bonds, portions of which mature annually from August 1, 2017 to August 1, 2021, and $632 million of term bonds, $278 million of which matures on August 1, 2026 and $354 million of which matures on August 1, 2031. In connection with the refinancing of the Prior JFK Bonds, American recorded a special nonoperating charge of $36 million consisting of non-cash (f) Senior Notes The details of our 5.50%, 6.125% and 4.625% senior notes are shown in the table below as of December 31, 2016: 5.50% Senior Notes 6.125% Senior Notes 4.625% Senior Notes Aggregate principal issued and outstanding $750 million $500 million $500 million Maturity date October 2019 June 2018 March 2020 Fixed interest rate per annum 5.50% 6.125% 4.625% Interest payments Semi-annually Semi-annually Semi-annually The 5.50% senior notes and the 4.625% senior notes are senior unsecured obligations of AAG. The 6.125% senior notes are general unsecured senior obligations of AAG. The senior notes are fully and unconditionally guaranteed by American. The indentures for the senior notes contain covenants and events of default generally customary for similar financings. In addition, if we experience specific kinds of changes of control, we must offer to repurchase the senior notes at a price of 101% of the principal amount plus accrued and unpaid interest, if any, to (but not including) the repurchase date. Upon the occurrence of certain events of default, the senior notes may be accelerated and become due and payable. Guarantees As of December 31, 2016, AAG had issued guarantees covering approximately $844 million of American’s special facility revenue bonds (and interest thereon) and $9.3 billion of American’s secured debt (and interest thereon), including the Credit Facilities and certain EETC financings. Collateral-Related Covenants Certain of our debt financing agreements contain loan to value (LTV) ratio covenants and require us to annually appraise the related collateral. Pursuant to such agreements, if the LTV ratio exceeds a specified threshold, we are required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash collateral), or pay down such financing, in whole or in part. Specifically, we are required to meet certain collateral coverage tests on an annual basis for four credit facilities, as described below: 2013 Credit Facilities 2014 Credit Facilities April 2016 Credit December 2016 Frequency of Appraisals of Appraised Collateral Annual Annual Annual Annual LTV Requirement 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) LTV as of Last Measurement Date 31.5% 23.2% 47.7% 61.8% Collateral Description Generally, certain slots, route authorities, and airport gate leasehold rights used by American to operate all services between the U.S. and South America Generally, certain slots, route authorities and airport gate leasehold rights used by American to operate certain services between the U.S. and London Heathrow Certain spare parts Generally, certain Ronald Reagan Washington National Airport (DCA) slots, certain La Guardia Airport (LGA) slots, and certain simulators At December 31, 2016, we were in compliance with the applicable collateral coverage tests as of the most recent measurement dates.

The 2013 and 2014 Revolving Facilities are each subject to an undrawn fee of 0.75%. As of December 31, 2016, there were no borrowings or letters of credit outstanding under the 2013 or 2014 Revolving Facilities. The April 2016 and December 2016 Credit Facilities each provide for a revolving credit facility that may be established in the future. Subject to certain limitations and exceptions, the Credit Facilities are secured by certain collateral, including spare parts, certain slots, route authorities and airport gate leasehold rights. American has the ability to make future modifications to the collateral pledged, subject to certain restrictions. American’s obligations under the Credit Facilities are guaranteed by AAG. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans as further described below in “Collateral-Related Covenants.” The Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and become due and payable immediately. In addition, if a “change of control” occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the Credit Facilities and terminate the 2013 and 2014 Revolving Facilities and any revolving credit facilities established under the April 2016 or December 2016 Credit Facilities. The Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions. (b) 2013 Citicorp Credit Facility On May 23, 2013, American entered into a term loan credit facility (as amended, the 2013 Citicorp Credit Facility) with Citicorp North America, Inc., as administrative agent, and certain lenders. The 2013 Citicorp Credit Facility consisted of Tranche B-1 B-2 (c) EETCs Issued in 2016 2016-1 In January 2016, American created three pass-through trusts which issued approximately $1.1 billion aggregate principal amount of Series 2016-1 2016-1 2016-1 2016-1 2016-1 The details of the 2016-1 2016-1 Series AA Series A Series B Aggregate principal issued $584 million $262 million $228 million Fixed interest rate per annum 3.575% 4.10% 5.25% Maturity date January 2028 January 2028 January 2024 2016-2 In May and July 2016, American created three pass-through trusts which issued approximately $1.1 billion aggregate principal amount of Series 2016-2 2016-2 2016-2 2016-2 2016-2 The details of the 2016-2 2016-2 Series AA Series A Series B Aggregate principal issued $567 million $261 million $227 million Fixed interest rate per annum 3.20% 3.65% 4.375% Maturity date June 2028 June 2028 June 2024 2016-3 In October 2016, American created two pass-through trusts which issued approximately $814 million aggregate principal amount of Series 2016-3 2016-3 2016-3 2016-3 2016-3 As of December 31, 2016, approximately $705 million of the escrowed proceeds from the 2016-3 2016-3 The details of the 2016-3 2016-3 Series AA Series A Aggregate principal issued $558 million $256 million Remaining escrowed proceeds $75 million $34 million Fixed interest rate per annum 3.00% 3.25% Maturity date October 2028 October 2028 (d) Equipment Loans and Other Notes Payable Issued in 2016 In 2016, American entered into loan agreements to borrow $1.8 billion in connection with the financing of certain aircraft. Debt incurred under these loan agreements matures in 2021 through 2028 and bears interest at fixed and variable rates of LIBOR plus an applicable margin averaging 2.96% at December 31, 2016. (e) Special Facility Revenue Bonds 2016 Financing Activity In June 2016, the New York Transportation Development Corporation (NYTDC) issued approximately $844 million of special facility revenue refunding bonds (the 2016 JFK Bonds) on behalf of American. The net proceeds from the 2016 JFK Bonds generally were used to provide a portion of the funds to refinance $1.0 billion of special facility revenue bonds (Prior JFK Bonds), the net proceeds of which partially financed the construction of a terminal (the Terminal) used by American at John F. Kennedy International Airport (JFK). American is required to pay debt service on the 2016 JFK Bonds through payments under a loan agreement with NYTDC, and American and AAG guarantee the 2016 JFK Bonds. American’s and AAG’s obligations under these guarantees are secured by a mortgage on American’s lease of the Terminal and related property from the Port Authority of New York and New Jersey. The 2016 JFK Bonds, in aggregate, were priced at approximately 107% of par value. The gross proceeds from the issuance of the 2016 JFK Bonds were approximately $907 million. Of this amount, approximately $895 million was used to partially fund the redemption of the Prior JFK Bonds. The 2016 JFK Bonds bear interest at 5.0% per annum and are comprised of $212 million of serial bonds, portions of which mature annually from August 1, 2017 to August 1, 2021, and $632 million of term bonds, $278 million of which matures on August 1, 2026 and $354 million of which matures on August 1, 2031. In connection with the refinancing of the Prior JFK Bonds, American recorded a special nonoperating charge of $36 million consisting of non-cash Guarantees As of December 31, 2016, American had issued guarantees covering AAG’s $750 million aggregate principal amount of 5.50% senior notes due 2019, $500 million aggregate principal amount of 6.125% senior notes due 2018 and $500 million aggregate principal amount of 4.625% senior notes due 2020. Collateral-Related Covenants Certain of American’s debt financing agreements contain loan to value (LTV) ratio covenants and require American to annually appraise the related collateral. Pursuant to such agreements, if the LTV ratio exceeds a specified threshold, American is required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash collateral), or pay down such financing, in whole or in part. Specifically, American is required to meet certain collateral coverage tests on an annual basis for four credit facilities, as described below: 2013 Credit Facilities 2014 Credit Facilities April 2016 Credit December 2016 Frequency of Appraisals of Appraised Collateral Annual Annual Annual Annual LTV Requirement 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) 1.6x Collateral valuation to amount of debt outstanding (62.5% LTV) LTV as of Last Measurement Date 31.5% 23.2% 47.7% 61.8% Collateral Description Generally, certain slots, route authorities, and airport gate leasehold rights used by American to operate all services between the U.S. and South America Generally, certain slots, route authorities and airport gate leasehold rights used by American to operate certain services between the U.S. and London Heathrow Certain spare parts Generally, certain Ronald Reagan Washington National Airport (DCA) slots, certain La Guardia Airport (LGA) slots, and certain simulators At December 31, 2016, American was in compliance with the applicable collateral coverage tests as of the most recent measurement dates.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our projections of future profitability, including risks associated with remaining Merger integration activities as well as other conditions which are beyond our control, such as the health of the economy, the level and volatility of fuel prices and travel demand. In connection with the preparation of our financial statements at the end of 2015, we determined that after considering all positive and negative evidence, including the completion of certain critical Merger integration milestones as well as our financial performance, it was more likely than not that substantially all of our deferred income tax assets, which include our NOLs, would be realized. Accordingly, we reversed $3.0 billion of the valuation allowance, which resulted in a special non-cash For the year ended December 31, 2014, we recorded a $330 million tax provision. During 2014, we sold our portfolio of fuel hedging contracts that were scheduled to settle on or after June 30, 2014. In connection with this sale, we recorded a special non-cash non-cash In addition to the changes in the valuation allowance from operations described in the table above, the valuation allowance was also impacted by the changes in the components of accumulated other comprehensive income (loss), described in Note 10. The total increase in the valuation allowance was $7 million in 2016. The total decrease in the valuation allowance was $4.8 billion and $197 million in 2015 and 2014, respectively. The components of our deferred tax assets and liabilities were (in millions): December 31, 2016 2015 Deferred tax assets: Operating loss carryforwards $ 3,853 $ 2,558 Pensions 2,610 2,436 Loyalty program liability 485 590 Alternative minimum tax credit carryforwards 344 346 Postretirement benefits other than pensions 291 340 Rent expense 256 134 Gains from lease transactions 213 262 Reorganization items 53 57 Other 972 1,200 Total deferred tax assets 9,077 7,923 Valuation allowance (29 ) (22 ) Net deferred tax assets 9,048 7,901 Deferred tax liabilities: Accelerated depreciation and amortization (7,216 ) (5,158 ) Other (345 ) (266 ) Total deferred tax liabilities (7,561 ) (5,424 ) Net deferred tax asset $ 1,487 $ 2,477 At December 31, 2016, we had approximately $10.5 billion of gross NOL Carryforwards to reduce future federal taxable income, substantially all of which are expected to be available for use in 2017. The federal NOL Carryforwards will expire beginning in 2022 if unused. We also had approximately $3.7 billion of NOL Carryforwards to reduce future state taxable income at December 31, 2016, which will expire in years 2017 through 2036 if unused. Our ability to deduct our NOL Carryforwards and to utilize certain other available tax attributes can be substantially constrained under the general annual limitation rules of Section 382 where an “ownership change” has occurred. Substantially all of our remaining federal NOL Carryforwards (attributable to US Airways Group) are subject to limitation under Section 382; however, our ability to utilize such NOL Carryforwards is not anticipated to be effectively constrained as a result of such limitation. We elected to be covered by certain special rules for federal income tax purposes that permitted approximately $9.0 billion (with $8.9 billion of unlimited NOL still remaining at December 31, 2016) of our federal NOL Carryforwards to be utilized without regard to the annual limitation generally imposed by Section 382. Similar limitations may apply for state income tax purposes. Our ability to utilize any new NOL Carryforwards arising after the ownership changes is not affected by the annual limitation rules imposed by Section 382 unless another future ownership change occurs. Under the Section 382 limitation, cumulative stock ownership changes among material stockholders exceeding 50% during a rolling three-year period can potentially limit a company’s future use of NOLs and tax credits. See Part I, Item 1A. Risk Factors – “Our ability to utilize our NOL Carryforwards may be limited” At December 31, 2016, we had an AMT credit carryforward of approximately $339 million available for federal income tax purposes, which is available for an indefinite period. In 2016, we recorded an income tax provision with an effective rate of approximately 38%, which was substantially non-cash We file our tax returns as prescribed by the tax laws of the jurisdictions in which we operate. Our 2013 through 2015 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination and we are under examination, in administrative appeals, or engaged in tax litigation in certain jurisdictions. We believe that the effect of any assessments will not be material to our consolidated financial statements. The amount of, and changes to, our uncertain tax positions were not material in any of the years presented. We accrue interest and penalties related to unrecognized tax benefits in interest expense and operating expense, respectively.

Risk Management	12 Months Ended

Risk Management	7. Risk Management Our economic prospects are heavily dependent upon two variables we cannot control: the health of the economy and the price of fuel. Due to the discretionary nature of business and leisure travel spending, airline industry revenues are heavily influenced by the condition of the U.S. economy and economies in other regions of the world. Unfavorable conditions in these broader economies have resulted, and may result in the future, in decreased passenger demand for air travel and changes in booking practices, both of which in turn have had, and may have in the future, a strong negative effect on our revenues. In addition, during challenging economic times, actions by our competitors to increase their revenues can have an adverse impact on our revenues. Our operating results are materially impacted by changes in the availability, price volatility and cost of aircraft fuel, which represents one of the largest single cost items in our business. Jet fuel market prices have fluctuated substantially over the past several years and prices continue to be highly volatile. Because of the amount of fuel needed to operate our business, even a relatively small increase or decrease in the price of fuel can have a material effect on our operating results and liquidity. These additional factors could impact our results of operations, financial performance and liquidity: (a) Credit Risk Most of our receivables relate to tickets sold to individual passengers through the use of major credit cards or to tickets sold by other airlines and used by passengers on American. These receivables are short-term, mostly settled within seven days after sale. Bad debt losses, which have been minimal in the past, have been considered in establishing allowances for doubtful accounts. We do not believe we are subject to any significant concentration of credit risk. (b) Interest Rate Risk We have exposure to market risk associated with changes in interest rates related primarily to our variable rate debt obligations. Interest rates on $9.6 billion principal amount of long-term debt as of December 31, 2016 are subject to adjustment to reflect changes in floating interest rates. The weighted average effective interest rate on our variable rate debt was 3.1% at December 31, 2016. We do not currently have an interest rate hedge program. (c) Foreign Currency Risk We are exposed to the effect of foreign exchange rate fluctuations on the U.S. dollar value of foreign currency-denominated operating revenues and expenses. Our largest exposure comes from the British pound, Euro, Canadian dollar and various Latin American currencies, primarily the Brazilian real. We do not currently have a foreign currency hedge program. See Part I, Item 1A.

Fair Value Measurements	8. Fair Value Measurements Assets Measured at Fair Value on a Recurring Basis Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (i.e. an exit price) on the measurement date in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. Accounting standards include disclosure requirements around fair values used for certain financial instruments and establish a fair value hierarchy. The hierarchy prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of three levels: • Level 1 – Observable inputs such as quoted prices in active markets; • Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and • Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. When available, we use quoted market prices to determine the fair value of our financial assets. If quoted market prices are not available, we measure fair value using valuation techniques that use, when possible, current market-based or independently-sourced market parameters, such as interest rates and currency rates. We utilize the market approach to measure fair value for our financial assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets.

Employee Benefit Plans

Employee Benefit Plans	12 Months Ended

Employee Benefit Plans	9. Employee Benefit Plans We sponsor defined benefit and defined contribution pension plans for eligible employees. The defined benefit pension plans provide benefits for participating employees based on years of service and average compensation for a specified period of time before retirement. Effective November 1, 2012, substantially all of our defined benefit pension plans were frozen and we began providing enhanced benefits under our defined contribution pension plans for certain groups. We use a December 31 measurement date for all of our defined benefit pension plans. We also provide certain retiree medical and other postretirement benefits, including health care and life insurance benefits, to retired employees. Effective November 1, 2012, we modified our retiree medical and other postretirement benefits plans to eliminate the company subsidy for employees who retire on or after November 1, 2012. As a result of modifications to our retiree medical and other postretirement benefits plans in 2012, we recognized a negative plan amendment of $1.9 billion, which is included as a component of actuarial gain in OCI and will be amortized over the future service life of the active plan participants for whom the benefit was eliminated, or approximately eight years. As of December 31, 2016, $871 million of actuarial gain remains to be amortized. Benefit Obligations, Fair Value of Plan Assets and Funded Status The following tables provide a reconciliation of the changes in the pension and retiree medical and other postretirement benefits obligations, fair value of plan assets and a statement of funded status as of December 31, 2016 and 2015: Pension Benefits Retiree Medical and Other 2016 2015 2016 2015 (In millions) Benefit obligation at beginning of period $ 16,395 $ 17,594 $ 1,131 $ 1,325 Service cost 2 2 3 3 Interest cost 749 737 47 50 Actuarial (gain) loss (1) (2) 729 (1,159 ) (105 ) (177 ) Plan amendments — — 7 — Settlements (2 ) (3 ) — — Benefit payments (635 ) (776 ) (92 ) (94 ) Other — — — 24 Benefit obligation at end of period $ 17,238 $ 16,395 $ 991 $ 1,131 Fair value of plan assets at beginning of period $ 9,707 $ 10,986 $ 253 $ 244 Actual return on plan assets 915 (506 ) 22 (10 ) Employer contributions 32 6 83 89 Settlements (2 ) (3 ) — — Benefit payments (635 ) (776 ) (92 ) (94 ) Other (3) — — — 24 Fair value of plan assets at end of period $ 10,017 $ 9,707 $ 266 $ 253 Funded status at end of period $ (7,221 ) $ (6,688 ) $ (725 ) $ (878 ) (1) The December 31, 2016 and 2015 pension actuarial (gain) loss primarily relates to weighted average discount rate assumption changes and changes to our mortality assumptions. (2) The December 31, 2016 and 2015 retiree medical and other postretirement benefits actuarial gain primarily relates to medical trend and cost assumption changes, favorable plan experience adjustments and weighted average discount rate assumption changes. (3) At December 31, 2015, certain trust assets totaling approximately $24 million, were added to the retiree medical and other postretirement benefits plans asset values that were previously offset against the benefit obligation.

The estimated amount of unrecognized net loss for the defined benefit pension plans that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost over the next fiscal year is $144 million. The estimated amount of unrecognized net gain for the retiree medical and other postretirement benefits plans that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost over the next fiscal year is $23 million. Assumptions The following actuarial assumptions were used to determine our benefit obligations and net periodic benefit cost for the periods presented: Pension Benefits Retiree Medical and Other Postretirement Benefits 2016 2015 2016 2015 Benefit obligations: Weighted average discount rate 4.30 % 4.70 % 4.10 % 4.42 % Pension Benefits Retiree Medical and Other Postretirement Benefits 2016 2015 2014 2016 2015 2014 Net periodic benefit cost: Weighted average discount rate 4.70 % 4.30 % 5.10 % 4.42 % 4.00 % 4.74 % Weighted average expected rate of return on plan assets 8.00 % 8.00 % 8.00 % 8.00 % 8.00 % 8.00 % Weighted average health care cost trend rate assumed for next year (1) N/A N/A N/A 4.25 % 5.21 % 5.25 % (1) The weighted average health care cost trend rate at December 31, 2016 is assumed to decline gradually to 3.77% by 2024 and remain level thereafter. As of December 31, 2016, our estimate of the long-term rate of return on plan assets was 8% based on the target asset allocation. Expected returns on long duration bonds are based on yields to maturity of the bonds held at year-end. A one percentage point change in the assumed health care cost trend rates would have the following effects on our retiree medical and other postretirement benefits plans (in millions): 1% Increase 1% Decrease Increase (decrease) on 2016 service and interest cost $ 3 $ (3 ) Increase (decrease) on benefit obligation as of December 31, 2016 53 (50 ) Minimum Contributions We are required to make minimum contributions to our defined benefit pension plans under the minimum funding requirements of the Employee Retirement Income Security Act of 1974 and various other laws for U.S. based plans as well as under funding rules specific to countries where we maintain defined benefit plans. Based on current funding assumptions, we have minimum required contributions of $25 million for 2017. We expect to make supplemental contributions of $254 million to our U.S. based defined benefit plans in 2017. Currently, the minimum funding obligation for our U.S. based defined benefit pension plans is subject to temporary favorable rules that are scheduled to expire at the end of 2017. Our pension funding obligations are likely to increase materially following expiration of the temporary funding rules, when we will be required to make contributions relating to the 2018 fiscal year. The amount of these obligations will depend on the performance of our investments held in trust by the pension plans, interest rates for determining liabilities, the amount of and timing of any supplemental contributions and our actuarial experience. Benefit Payments The following benefit payments, which reflect expected future service as appropriate, are expected to be paid (approximately, in millions): 2017 2018 2019 2020 2021 2022-2026 Pension $ 688 $ 722 $ 762 $ 804 $ 845 $ 4,819 Retiree medical and other postretirement benefits 97 93 88 79 73 312 Plan Assets The objectives of our investment policies are to: maintain sufficient income and liquidity to pay retirement benefits; produce a long-term rate of return that meets or exceeds the assumed rate of return for plan assets; limit the volatility of asset performance and funded status; and diversify assets among asset classes and investment managers. Based on these investment objectives, a long-term strategic asset allocation has been established. This strategic allocation seeks to balance the potential benefit of improving funded position with the potential risk that the funded position would decline. The current strategic target asset allocation is as follows: Asset Class/Sub-Class Allowed Range Equity 65% - 90% Public: U.S. 20% - 45% International 17% - 27% Emerging Markets 5% - 11% Alternative Investments 5% - 30% Fixed Income 15% - 40% U.S. Long Duration 15% - 40% High Yield and Emerging Markets 0% - 10% Other 0% - 5% Cash Equivalents 0% - 5% Public equity and emerging market fixed income securities are used to provide diversification and are expected to generate higher returns over the long-term than U.S. long duration bonds. Public stocks are managed using a value investment approach in order to participate in the returns generated by stocks in the long-term, while reducing year-over-year volatility. U.S. long duration bonds are used to partially hedge the assets from declines in interest rates. Alternative (private) investments are used to provide expected returns in excess of the public markets over the long-term. Additionally, the pension plan’s master trust engages currency overlay managers in an attempt to increase returns by protecting non-U.S. Investments in securities traded on recognized securities exchanges are valued at the last reported sales price on the last business day of the year.

(2) The December 31, 2016 and 2015 retiree medical and other postretirement benefits actuarial gain primarily relates to medical trend and cost assumption changes, favorable plan experience adjustments and weighted average discount rate assumption changes. (3) At December 31, 2015, certain trust assets totaling approximately $24 million, were added to the retiree medical and other postretirement benefits plans asset values that were previously offset against the benefit obligation.

The estimated amount of unrecognized net loss for the defined benefit pension plans that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost over the next fiscal year is $144 million. The estimated amount of unrecognized net gain for the retiree medical and other postretirement benefits plans that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost over the next fiscal year is $23 million. Assumptions The following actuarial assumptions were used to determine American’s benefit obligations and net periodic benefit cost for the periods presented: Pension Benefits Retiree Medical and Other Postretirement Benefits 2016 2015 2016 2015 Benefit obligations: Weighted average discount rate 4.30 % 4.70 % 4.10 % 4.42 % Pension Benefits Retiree Medical and Other Postretirement Benefits 2016 2015 2014 2016 2015 2014 Net periodic benefit cost: Weighted average discount rate 4.70 % 4.30 % 5.10 % 4.42 % 4.00 % 4.74 % Weighted average expected rate of return on plan assets 8.00 % 8.00 % 8.00 % 8.00 % 8.00 % 8.00 % Weighted average health care cost trend rate assumed for next year (1) N/A N/A N/A 4.25 % 5.21 % 5.25 % (1) The weighted average health care cost trend rate at December 31, 2016 is assumed to decline gradually to 3.77% by 2024 and remain level thereafter. As of December 31, 2016, American’s estimate of the long-term rate of return on plan assets was 8% based on the target asset allocation. Expected returns on long duration bonds are based on yields to maturity of the bonds held at year-end. A one percentage point change in the assumed health care cost trend rates would have the following effects on American’s retiree medical and other postretirement benefits plans (in millions): 1% Increase 1% Decrease Increase (decrease) on 2016 service and interest cost $ 3 $ (3 ) Increase (decrease) on benefit obligation as of December 31, 2016 53 (50 ) Minimum Contributions American is required to make minimum contributions to its defined benefit pension plans under the minimum funding requirements of the Employee Retirement Income Security Act of 1974 and various other laws for U.S. based plans as well as under funding rules specific to countries where American maintains defined benefit plans. Based on current funding assumptions, American has minimum required contributions of $25 million for 2017. American expects to make supplemental contributions of $254 million to its U.S. based defined benefit plans in 2017. Currently, the minimum funding obligation for American’s U.S. based defined benefit pension plans is subject to temporary favorable rules that are scheduled to expire at the end of 2017. American’s pension funding obligations are likely to increase materially following expiration of the temporary funding rules, when American will be required to make contributions relating to the 2018 fiscal year. The amount of these obligations will depend on the performance of American’s investments held in trust by the pension plans, interest rates for determining liabilities, the amount of and timing of any supplemental contributions and American’s actuarial experience. Benefit Payments The following benefit payments, which reflect expected future service as appropriate, are expected to be paid (approximately, in millions): 2017 2018 2019 2020 2021 2022-2026 Pension $ 685 $ 719 $ 758 $ 800 $ 841 $ 4,797 Retiree medical and other postretirement benefits 97 93 88 79 73 312 Plan Assets The objectives of American’s investment policies are to: maintain sufficient income and liquidity to pay retirement benefits; produce a long-term rate of return that meets or exceeds the assumed rate of return for plan assets; limit the volatility of asset performance and funded status; and diversify assets among asset classes and investment managers. Based on these investment objectives, a long-term strategic asset allocation has been established. This strategic allocation seeks to balance the potential benefit of improving funded position with the potential risk that the funded position would decline. The current strategic target asset allocation is as follows: Asset Class/Sub-Class Allowed Range Equity 65% - 90% Public: U.S. 20% - 45% International 17% - 27% Emerging Markets 5% - 11% Alternative Investments 5% - 30% Fixed Income 15% - 40% U.S. Long Duration 15% - 40% High Yield and Emerging Markets 0% - 10% Other 0% - 5% Cash Equivalents 0% - 5% Public equity and emerging market fixed income securities are used to provide diversification and are expected to generate higher returns over the long-term than U.S. long duration bonds. Public stocks are managed using a value investment approach in order to participate in the returns generated by stocks in the long-term, while reducing year-over-year volatility. U.S. long duration bonds are used to partially hedge the assets from declines in interest rates. Alternative (private) investments are used to provide expected returns in excess of the public markets over the long-term. Additionally, the pension plan’s master trust engages currency overlay managers in an attempt to increase returns by protecting non-U.S. Investments in securities traded on recognized securities exchanges are valued at the last reported sales price on the last business day of the year.

Commitments, Contingencies and

Commitments, Contingencies and Guarantees	12 Months Ended
	Dec. 31, 2016
Commitments, Contingencies and Guarantees	11. Commitments, Contingencies and Guarantees (a) Aircraft and Engine Purchase Commitments Under all of our aircraft and engine purchase agreements, our total future commitments as of December 31, 2016 are expected to be as follows (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Payments for aircraft commitments and certain engines (1) $ 4,064 $ 2,192 $ 3,113 $ 3,133 $ 2,948 $ 2,553 $ 18,003 (1) These amounts are net of purchase deposits currently held by the manufacturers and include all commitments for regional aircraft. American has granted a security interest in its purchase deposits with Boeing. Our purchase deposits held by all manufacturers totaled $1.2 billion as of December 31, 2016. (b) Facility and support commitments We have contracts related to facility construction or improvement projects, primarily at airport locations, as well as information technology support. The contractual obligations related to these contracts are presented in the table below (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Facility construction or improvement contracts $ 182 $ 126 $ 13 $ — $ — $ — $ 321 Information technology contracts 205 168 128 47 24 8 580 (c) Capacity Purchase Agreements with Third-Party Regional Carriers American has capacity purchase agreements with third-party regional carriers. The capacity purchase agreements provide that all revenues, including passenger, in-flight, As of December 31, 2016, American’s capacity purchase agreements with third-party regional carriers had expiration dates ranging from 2017 to 2027, with rights of American to extend the respective terms of certain agreements. See Part I, Item 2. Properties for unaudited information on the aircraft operated by third-party regional carriers under such capacity purchase agreements. As of December 31, 2016, American’s minimum fixed obligations under its capacity purchase agreements with third-party regional carriers are as follows (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Minimum fixed obligations under capacity purchase agreements with third-party regional carriers (1) $ 1,710 $ 1,421 $ 1,283 $ 1,048 $ 855 $ 2,738 $ 9,055 (1) Represents minimum payments under capacity purchase agreements with third-party regional carriers. These commitments are estimates of costs based on assumed minimum levels of flying under the capacity purchase agreements and American’s actual payments could differ materially. These obligations also include the portion of American’s future obligations related to aircraft deemed to be leased in the amount of approximately $434 million in 2017, $370 million in 2018, $349 million in 2019, $317 million in 2020, $280 million in 2021 and $927 million in 2022 and thereafter. (d) Operating Leases We lease certain aircraft, engines and ground equipment, in addition to the majority of our ground facilities and terminal space. As of December 31, 2016, we had 419 aircraft under operating leases, with remaining terms ranging from three months to approximately 11 years. Airports are utilized for flight operations under lease arrangements with the municipalities or agencies owning or controlling such airports. Substantially all leases provide that the lessee must pay taxes, maintenance, insurance and certain other operating expenses applicable to the leased property. Some leases also include renewal and purchase options. As of December 31, 2016, obligations under noncancellable operating leases for future minimum lease payments are as follows (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Future minimum lease payments $ 2,250 $ 2,016 $ 1,815 $ 1,639 $ 1,214 $ 3,793 $ 12,727 Mainline and regional rent expense, excluding landing fees, was $2.8 billion in each of 2016, 2015 and 2014. (e) Off-Balance Aircraft American currently operates 346 owned aircraft and 138 leased aircraft which were financed with EETCs issued by pass-through trusts. These trusts are off-balance Each trust covers a set number of aircraft scheduled to be delivered or refinanced upon the issuance of the EETC or within a specific period of time thereafter. At the time of each covered aircraft financing, the relevant trust used the proceeds of the issuance of the EETC (which may have been available at the time of issuance thereof or held in escrow until financing of the applicable aircraft following its delivery) to purchase equipment notes relating to the financed aircraft. The equipment notes are issued, at American’s election, in connection with a mortgage financing of the aircraft or, in certain cases, by a separate owner trust in connection with a leveraged lease financing of the aircraft. In the case of a leveraged lease financing, the owner trust then leases the aircraft to American. In both cases, the equipment notes are secured by a security interest in the aircraft. The pass-through trust certificates are not direct obligations of, nor are they guaranteed by, AAG or American. However, in the case of mortgage financings, the equipment notes issued to the trusts are direct obligations of American and, in certain instances, have been guaranteed by AAG. As of December 31, 2016, $10.9 billion associated with these mortgage financings is reflected as debt in the accompanying consolidated balance sheet. With respect to leveraged leases, American evaluated whether the leases had characteristics of a variable interest entity. American concluded the leasing entities met the criteria for variable interest entities. American generally is not the primary beneficiary of the leasing entities if the lease terms are consistent with market terms at the inception of the lease and do not include a residual value guarantee, fixed-price purchase option or similar feature that obligates American to absorb decreases in value or entitles American to participate in increases in the value of the aircraft. American does not provide residual value guarantees to the bondholders or equity participants in the trusts. Some leases have a fair market value or a fixed price purchase option that allows American to purchase the aircraft at or near the end of the lease term. However, the option price approximates an estimate of the aircraft’s fair value at the option date. Under this feature, American does not participate in any increases in the value of the aircraft. American concluded it is not the primary beneficiary under these arrangements. Therefore, American accounts for its EETC leveraged lease financings as operating leases. American’s total future obligations under these leveraged lease financings are $1.5 billion as of December 31, 2016, which are included in the future minimum lease payments table above. Special Facility Revenue Bonds AAG guarantees the payment of principal and interest of certain special facility revenue bonds issued by municipalities primarily to build or improve airport facilities and purchase equipment which is leased to American. Under such leases, American is required to make rental payments through 2035, sufficient to pay maturing principal and interest payments on the related bonds. As of December 31, 2016, the remaining lease payments guaranteeing the principal and interest on these bonds are $605 million, which are accounted for as operating leases. (f) Legal Proceedings Chapter 11 Cases Pursuant to rulings of the Bankruptcy Court, the Plan established the Disputed Claims Reserve to hold shares of AAG common stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed claims. As of December 31, 2016, there were approximately 25.2 million shares of AAG common stock remaining in the Disputed Claims Reserve. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve on the same basis as if such distributions had been made on or about the Effective Date. However, we are not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay any additional allowed unsecured claims. To the extent that any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to us but rather will be distributed to former AMR stockholders. There is also pending in the Bankruptcy Court an adversary proceeding relating to an action brought by American to seek a determination that certain non-pension, non-union DOJ Antitrust Civil Investigative Demand Private Party Antitrust Action re-filed DOJ Investigation Related to the United States Postal Service General “We may be a party to litigation in the normal course of business or otherwise, which could affect our financial position and liquidity” (g) Guarantees and Indemnifications We are party to many routine contracts in which we provide general indemnities in the normal course of business to third parties for various risks. We are not able to estimate the potential amount of any liability resulting from the indemnities. These indemnities are discussed in the following paragraphs. In our aircraft financing agreements, we generally indemnify the financing parties, trustees acting on their behalf and other relevant parties against liabilities (including certain taxes) resulting from the financing, manufacture, design, ownership, operation and maintenance of the aircraft regardless of whether these liabilities (or taxes) relate to the negligence of the indemnified parties. Our loan agreements and other LIBOR-based financing transactions (including certain leveraged aircraft leases) generally obligate us to reimburse the applicable lender for incremental costs due to a change in law that imposes (i) any reserve or special deposit requirement against assets of, deposits with or credit extended by such lender related to the loan, (ii) any tax, duty or other charge with respect to the loan (except standard income tax) or (iii) capital adequacy requirements. In addition, our loan agreements and other financing arrangements typically contain a withholding tax provision that requires us to pay additional amounts to the applicable lender or other financing party, generally if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law. These increased cost and withholding tax provisions continue for the entire term of the applicable transaction, and there is no limitation on the maximum additional amounts we could be obligated to pay under such provisions. Any failure to pay amounts due under such provisions generally would trigger an event of default and, in a secured financing transaction, would entitle the lender to foreclose on the collateral to realize the amount due. In certain transactions, including certain aircraft financing leases and loans, the lessors, lenders and/or other parties have rights to terminate the transaction based on changes in foreign tax law, illegality or certain other events or circumstances. In such a case, we may be required to make a lump sum payment to terminate the relevant transaction. We have general indemnity clauses in many of our airport and other real estate leases where we as lessee indemnify the lessor (and related parties) against liabilities related to our use of the leased property. Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties. In addition, we provide environmental indemnities in many of these leases for contamination related to our use of the leased property. Under certain contracts with third parties, we indemnify the third-party against legal liability arising out of an action by the third-party, or certain other parties. The terms of these contracts vary and the potential exposure under these indemnities cannot be determined. We have liability insurance protecting us for some of the obligations we have undertaken under these indemnities. We are involved in certain claims and litigation related to our operations. We are also subject to regulatory assessments in the ordinary course of business. We establish reserves for litigation and regulatory matters when those matters present loss contingencies that are both probable and can be reasonably estimated. In the opinion of management, liabilities, if any, arising from these regulatory matters, claims and litigation will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows, after consideration of available insurance. As of December 31, 2016, AAG had issued guarantees covering approximately $844 million of American’s special facility revenue bonds (and interest thereon) and $9.3 billion of American’s secured debt (and interest thereon), including the Credit Facilities and certain EETC financings. (h) Credit Card Processing Agreements We have agreements with companies that process customer credit card transactions for the sale of air travel and other services. Our agreements allow these processing companies, under certain conditions, to hold an amount of our cash (referred to as a holdback) equal to a portion of advance ticket sales that have been processed by that company, but for which we have not yet provided the air transportation. Additional holdback requirements in the event of material adverse changes in our financial condition will reduce our liquidity in the form of unrestricted cash by the amount of the holdbacks. We are not currently required to maintain any holdbacks pursuant to these requirements. (i) Labor Negotiations As of December 31, 2016, we employed approximately 122,300 active full-time equivalent employees, of which 20,800 were employed by our regional operations. Approximately 85% of employees are covered by collective bargaining agreements with various labor unions. Negotiations for joint collective bargaining agreements covering our mainline maintenance, fleet service, stores and planner employees as well as for certain employee groups at our wholly-owned regional subsidiaries are continuing. There is no assurance that a successful or timely resolution of these labor negotiations will be achieved. (j) Other As a result of the terrorist attacks of September 11, 2001 and the subsequent liability protections provided for by the Air Transportation Safety and System Stabilization Act (the Stabilization Act), we recorded a liability for these terrorist attacks claims equal to the related insurance receivable due to us. The Stabilization Act provides that, notwithstanding any other provision of law, liability for all claims, whether compensatory or punitive, arising from these terrorist attacks, against any air carrier shall not exceed the liability coverage maintained by the air carrier. As of December 31, 2016, the remaining liability and the amount of the offsetting receivable were each $974 million.

Commitments, Contingencies and Guarantees	9. Commitments, Contingencies and Guarantees (a) Aircraft and Engine Purchase Commitments Under all of American’s aircraft and engine purchase agreements, its total future commitments as of December 31, 2016 are expected to be as follows (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Payments for aircraft commitments and certain engines (1) $ 4,064 $ 2,192 $ 3,113 $ 3,133 $ 2,948 $ 2,553 $ 18,003 (1) These amounts are net of purchase deposits currently held by the manufacturers and include all commitments for regional aircraft. American has granted a security interest in its purchase deposits with Boeing. American’s purchase deposits held by all manufacturers totaled $1.2 billion as of December 31, 2016. (b) Facility and support commitments American has contracts related to facility construction or improvement projects, primarily at airport locations, as well as information technology support. The contractual obligations related to these contracts are presented in the table below (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Facility construction or improvement contracts $ 182 $ 126 $ 13 $ — $ — $ — $ 321 Information technology contracts 205 168 128 47 24 8 580 (c) Capacity Purchase Agreements with Third-Party Regional Carriers American has capacity purchase agreements with third-party regional carriers. The capacity purchase agreements provide that all revenues, including passenger, in-flight, As of December 31, 2016, American’s capacity purchase agreements with third-party regional carriers had expiration dates ranging from 2017 to 2027, with rights of American to extend the respective terms of certain agreements. See Part I, Item 2. Properties for unaudited information on the aircraft operated by third-party regional carriers under such capacity purchase agreements. As of December 31, 2016, American’s minimum fixed obligations under its capacity purchase agreements with third-party regional carriers are as follows (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Minimum fixed obligations under capacity purchase agreements with third-party regional carriers (1) $ 1,710 $ 1,421 $ 1,283 $ 1,048 $ 855 $ 2,738 $ 9,055 (1) Represents minimum payments under capacity purchase agreements with third-party regional carriers. These commitments are estimates of costs based on assumed minimum levels of flying under the capacity purchase agreements and American’s actual payments could differ materially. These obligations also include the portion of American’s future obligations related to aircraft deemed to be leased in the amount of approximately $434 million in 2017, $370 million in 2018, $349 million in 2019, $317 million in 2020, $280 million in 2021 and $927 million in 2022 and thereafter. (d) Operating Leases American leases certain aircraft, engines and ground equipment, in addition to the majority of its ground facilities and terminal space. As of December 31, 2016, American had 408 aircraft under operating leases, with remaining terms ranging from three months to approximately 11 years. Airports are utilized for flight operations under lease arrangements with the municipalities or agencies owning or controlling such airports. Substantially all leases provide that the lessee must pay taxes, maintenance, insurance and certain other operating expenses applicable to the leased property. Some leases also include renewal and purchase options. As of December 31, 2016, obligations under noncancellable operating leases for future minimum lease payments are as follows (approximately, in millions): 2017 2018 2019 2020 2021 2022 and Thereafter Total Future minimum lease payments $ 2,242 $ 2,010 $ 1,813 $ 1,638 $ 1,213 $ 3,785 $ 12,701 Mainline and regional rent expense, excluding landing fees, was $2.7 billion in each of 2016 and 2015 and $2.8 billion in 2014. (e) Off-Balance Aircraft American currently operates 346 owned aircraft and 138 leased aircraft which were financed with EETCs issued by pass-through trusts. These trusts are off-balance Each trust covers a set number of aircraft scheduled to be delivered or refinanced upon the issuance of the EETC or within a specific period of time thereafter. At the time of each covered aircraft financing, the relevant trust used the proceeds of the issuance of the EETC (which may have been available at the time of issuance thereof or held in escrow until financing of the applicable aircraft following its delivery) to purchase equipment notes relating to the financed aircraft. The equipment notes are issued, at American’s election, in connection with a mortgage financing of the aircraft or, in certain cases, by a separate owner trust in connection with a leveraged lease financing of the aircraft. In the case of a leveraged lease financing, the owner trust then leases the aircraft to American. In both cases, the equipment notes are secured by a security interest in the aircraft. The pass-through trust certificates are not direct obligations of, nor are they guaranteed by, AAG or American. However, in the case of mortgage financings, the equipment notes issued to the trusts are direct obligations of American and, in certain instances, have been guaranteed by AAG. As of December 31, 2016, $10.9 billion associated with these mortgage financings is reflected as debt in the accompanying consolidated balance sheet. With respect to leveraged leases, American evaluated whether the leases had characteristics of a variable interest entity. American concluded the leasing entities met the criteria for variable interest entities. American generally is not the primary beneficiary of the leasing entities if the lease terms are consistent with market terms at the inception of the lease and do not include a residual value guarantee, fixed-price purchase option or similar feature that obligates American to absorb decreases in value or entitles American to participate in increases in the value of the aircraft. American does not provide residual value guarantees to the bondholders or equity participants in the trusts. Some leases have a fair market value or a fixed price purchase option that allows American to purchase the aircraft at or near the end of the lease term. However, the option price approximates an estimate of the aircraft’s fair value at the option date. Under this feature, American does not participate in any increases in the value of the aircraft. American concluded it is not the primary beneficiary under these arrangements. Therefore, American accounts for its EETC leveraged lease financings as operating leases. American’s total future obligations under these leveraged lease financings are $1.5 billion as of December 31, 2016, which are included in the future minimum lease payments table above. Special Facility Revenue Bonds American guarantees the payment of principal and interest of certain special facility revenue bonds issued by municipalities primarily to build or improve airport facilities and purchase equipment which is leased to American. Under such leases, American is required to make rental payments through 2035, sufficient to pay maturing principal and interest payments on the related bonds. As of December 31, 2016, the remaining lease payments guaranteeing the principal and interest on these bonds are $605 million, which are accounted for as operating leases. (f) Legal Proceedings Chapter 11 Cases Pursuant to rulings of the Bankruptcy Court, the Plan established the Disputed Claims Reserve to hold shares of AAG common stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed claims. As of December 31, 2016, there were approximately 25.2 million shares of AAG common stock remaining in the Disputed Claims Reserve. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve on the same basis as if such distributions had been made on or about the Effective Date. However, American is not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay any additional allowed unsecured claims. To the extent that any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to American but rather will be distributed to former AMR stockholders. There is also pending in the Bankruptcy Court an adversary proceeding relating to an action brought by American to seek a determination that certain non-pension, non-union DOJ Antitrust Civil Investigative Demand Private Party Antitrust Action re-filed DOJ Investigation Related to the United States Postal Service General “We may be a party to litigation in the normal course of business or otherwise, which could affect our financial position and liquidity” (g) Guarantees and Indemnifications American is a party to many routine contracts in which it provides general indemnities in the normal course of business to third parties for various risks.

Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties. In addition, American provides environmental indemnities in many of these leases for contamination related to American’s use of the leased property.

In the opinion of management, liabilities, if any, arising from these regulatory matters, claims and litigation will not have a material adverse effect on American’s consolidated financial position, results of operations, or cash flows, after consideration of available insurance. As of December 31, 2016, American had issued guarantees covering AAG’s $750 million aggregate principal amount of 5.50% senior notes due 2019, $500 million aggregate principal amount of 6.125% senior notes due 2018 and $500 million aggregate principal amount of 4.625% senior notes due 2020. (h) Credit Card Processing Agreements American has agreements with companies that process customer credit card transactions for the sale of air travel and other services. American’s agreements allow these processing companies, under certain conditions, to hold an amount of its cash (referred to as a holdback) equal to a portion of advance ticket sales that have been processed by that company, but for which American has not yet provided the air transportation.

American is not currently required to maintain any holdbacks pursuant to these requirements. (i) Labor Negotiations As of December 31, 2016, American employed approximately 101,500 active full-time equivalent employees. Approximately 84% of employees are covered by collective bargaining agreements with various labor unions. Negotiations for joint collective bargaining agreements covering American’s maintenance, fleet service, stores and planner employees are continuing. There is no assurance that a successful or timely resolution of these labor negotiations will be achieved. (j) Other As a result of the terrorist attacks of September 11, 2001 and the subsequent liability protections provided for by the Air Transportation Safety and System Stabilization Act (the Stabilization Act), American recorded a liability for these terrorist attacks claims equal to the related insurance receivable due to American. The Stabilization Act provides that, notwithstanding any other provision of law, liability for all claims, whether compensatory or punitive, arising from these terrorist attacks, against any air carrier shall not exceed the liability coverage maintained by the air carrier. As of December 31, 2016, the remaining liability and the amount of the offsetting receivable were each $974 million.

Operating Segments and Related Disclosures	13. Operating Segments and Related Disclosures We are managed as a single business unit that provides air transportation for passengers and cargo. This allows us to benefit from an integrated revenue pricing and route network that includes American and our wholly-owned and third-party regional carriers that fly under capacity purchase agreements operating as American Eagle. The flight equipment of all these carriers is combined to form one fleet that is deployed through a single route scheduling system. When making resource allocation decisions, the chief operating decision maker evaluates flight profitability data, which considers aircraft type and route economics, but gives no weight to the financial impact of the resource allocation decision on an individual carrier basis. The objective in making resource allocation decisions is to maximize consolidated financial results, not the individual results of American or American Eagle.

Share-based Compensation	14. Share-based Compensation The 2013 AAG Incentive Award Plan (the 2013 Plan) provides that awards may be in the form of an option, restricted stock award, restricted stock unit award, performance award, dividend equivalent award, deferred stock award, deferred stock unit award, stock payment award or stock appreciation right. The 2013 Plan authorizes the grant of awards for the issuance of 40 million shares. Any shares underlying awards granted under the 2013 Plan, or any pre-existing Our net income for the years ended December 31, 2016, 2015 and 2014 included $102 million, $274 million and $381 million, respectively, of share-based compensation costs. Of the 2015 and 2014 amounts, $198 million and $224 million, respectively, were related to awards granted to certain employees in connection with the Merger and recorded in special items, net on the accompanying consolidated statements of operations. During 2016, 2015 and 2014, we withheld approximately 1.4 million, 7.0 million and 1.7 million shares of AAG common stock, respectively, and paid approximately $56 million, $306 million and $62 million, respectively, in satisfaction of certain tax withholding obligations associated with employee equity awards. (a) Restricted Stock Unit Awards (RSUs) We have granted RSUs with service conditions (time vested primarily over three years) and performance conditions. The grant-date fair value of RSUs is equal to the market price of the underlying shares of common stock on the date of grant. For time vested awards, the expense is recognized on a straight-line basis over the vesting period for the entire award. For awards with performance conditions, the expense is recognized based on the expected achievement at each reporting period. Stock-settled RSUs are classified as equity awards as the vesting results in the issuance of shares of AAG common stock. Cash-settled restricted stock unit awards (CRSUs) are classified as liability awards as the vesting results in payment of cash. Stock-settled RSU award activity for all plans for the years ended December 31, 2016, 2015 and 2014 is as follows (shares in thousands): Number of Shares Weighted Value (In thousands) Outstanding at December 31, 2013 23,879 $ 24.33 Granted 3,467 37.07 Vested and released (4,193 ) 23.84 Forfeited (1,811 ) 25.10 Outstanding at December 31, 2014 21,342 $ 26.43 Granted 2,213 46.62 Vested and released (17,163 ) 25.20 Forfeited (785 ) 27.12 Outstanding at December 31, 2015 5,607 $ 38.08 Granted 2,655 41.34 Vested and released (2,754 ) 34.83 Forfeited (321 ) 40.15 Outstanding at December 31, 2016 5,187 $ 41.48 As of December 31, 2016, there was $116 million of unrecognized compensation cost related to stock-settled RSUs. These costs are expected to be recognized over a weighted average period of one year. The total fair value of stock-settled RSUs vested during the years ended December 31, 2016, 2015 and 2014 was $107 million, $750 million and $154 million, respectively. As of December 31, 2016, we had a nominal amount of CRSUs outstanding. The total cash paid for CRSUs vested during the years ended December 31, 2016, 2015 and 2014 was less than $1 million, $10 million and $12 million, respectively. (b) Stock Options and Stock Appreciation Rights We assumed US Airways Group’s outstanding stock options and stock appreciation rights in connection with the Merger using an exchange ratio of one to one. These stock options and stock appreciation rights were granted with an exercise price equal to the underlying common stock’s fair value at the date of each grant, have service conditions, become exercisable over a three-year vesting period and expire if unexercised at the end of their term, which ranges from seven to ten years. Stock options and stock-settled stock appreciation rights (SARs) are classified as equity awards as the exercise results in the issuance of shares of AAG common stock. Cash-settled stock appreciation rights (CSARs) are classified as liability awards as the exercise results in payment of cash. Compensation costs were expensed on a straight-line basis over the vesting period for the entire award. There are no unrecognized compensation costs as all awards outstanding are vested. Stock option and SAR award activity for all plans for the years ended December 31, 2016, 2015 and 2014 is as follows (stock options and SARs in thousands): Stock Options SARs Weighted Weighted Aggregate (In thousands) (In years) (In millions) Balance at December 31, 2013 11,158 $ 12.84 Granted — — Exercised (4,109 ) 10.74 Forfeited — — Expired (42 ) 41.73 Balance at December 31, 2014 7,007 $ 13.90 Granted — — Exercised (2,985 ) 12.09 Forfeited — — Expired (9 ) 45.75 Balance at December 31, 2015 4,013 $ 15.17 Granted — — Exercised (1,738 ) 14.49 Forfeited — — Expired (180 ) 46.19 Balance at December 31, 2016 2,095 $ 13.08 1.6 $ 70 The total intrinsic value of stock options and SARs exercised during the years ended December 31, 2016, 2015 and 2014 was $49 million, $102 million and $105 million, respectively.

Cash-settled restricted stock unit awards (CRSUs) are classified as liability awards as the vesting results in payment of cash by AAG. Stock-settled RSU award activity for all plans for the years ended December 31, 2016, 2015 and 2014 is as follows (shares in thousands): Number of Shares Weighted Value (In thousands) Outstanding at December 31, 2013 23,879 $ 24.33 Granted 3,467 37.07 Vested and released (4,193 ) 23.84 Forfeited (1,811 ) 25.10 Outstanding at December 31, 2014 21,342 $ 26.43 Granted 2,213 46.62 Vested and released (17,163 ) 25.20 Forfeited (785 ) 27.12 Outstanding at December 31, 2015 5,607 $ 38.08 Granted 2,655 41.34 Vested and released (2,754 ) 34.83 Forfeited (321 ) 40.15 Outstanding at December 31, 2016 5,187 $ 41.48 As of December 31, 2016, there was $116 million of unrecognized compensation cost related to stock-settled RSUs. These costs are expected to be recognized over a weighted average period of one year. The total fair value of stock-settled RSUs vested during the years ended December 31, 2016, 2015 and 2014 was $107 million, $750 million and $154 million, respectively. As of December 31, 2016, AAG had a nominal amount of CRSUs outstanding. The total cash paid for CRSUs vested during the years ended December 31, 2016, 2015 and 2014 was less than $1 million, $10 million and $12 million, respectively. (b) Stock Options and Stock Appreciation Rights AAG assumed US Airways Group’s outstanding stock options and stock appreciation rights in connection with the Merger using an exchange ratio of one to one. These stock options and stock appreciation rights were granted with an exercise price equal to the underlying common stock’s fair value at the date of each grant, have service conditions, become exercisable over a three-year vesting period and expire if unexercised at the end of their term, which ranges from seven to ten years. Stock options and stock-settled stock appreciation rights (SARs) are classified as equity awards as the exercise results in the issuance of shares of AAG common stock. Cash-settled stock appreciation rights (CSARs) are classified as liability awards as the exercise results in payment of cash by AAG. Compensation costs were expensed on a straight-line basis over the vesting period for the entire award. There are no unrecognized compensation costs as all awards outstanding are vested. Stock option and SAR award activity for all plans for the years ended December 31, 2016, 2015 and 2014 is as follows (stock options and SARs in thousands): Stock Options and SARs Weighted Weighted Average Aggregate (In thousands) (In years) (In millions) Balance at December 31, 2013 11,158 $ 12.84 Granted — — Exercised (4,109 ) 10.74 Forfeited — — Expired (42 ) 41.73 Balance at December 31, 2014 7,007 $ 13.90 Granted — — Exercised (2,985 ) 12.09 Forfeited — — Expired (9 ) 45.75 Balance at December 31, 2015 4,013 $ 15.17 Granted — — Exercised (1,738 ) 14.49 Forfeited — — Expired (180 ) 46.19 Balance at December 31, 2016 2,095 $ 13.08 1.6 $ 70 The total intrinsic value of stock options and SARs exercised during the years ended December 31, 2016, 2015 and 2014 was $49 million, $102 million and $105 million, respectively.

Pursuant to a capacity purchase agreement between American and AAG’s wholly-owned regional airlines operating as American Eagle, American purchases all of the capacity from these carriers and recognizes passenger revenue from flights operated by American Eagle. In 2016, 2015 and 2014, American recognized expense of approximately $1.5 billion, $1.2 billion and $1.2 billion, respectively, related to wholly-owned regional airline capacity purchase agreements.

Basis of Presentation and Sum27

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Basis of Presentation	(a) Basis of Presentation American Airlines Group Inc. (we, us, our and similar terms, or AAG), a Delaware corporation, is a holding company whose primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo through its mainline operating subsidiary, American Airlines, Inc. (American) and its wholly-owned regional airline subsidiaries, Envoy Aviation Group Inc. (Envoy), Piedmont Airlines, Inc. (Piedmont) and PSA Airlines, Inc. (PSA) that operate under capacity purchase agreements as American Eagle. On December 9, 2013, a subsidiary of AMR merged with and into US Airways Group, Inc. (US Airways Group), a Delaware corporation, which survived as a wholly-owned subsidiary of AAG, and AAG emerged from Chapter 11 (the Merger). Upon closing of the Merger and emergence from Chapter 11, AMR changed its name to American Airlines Group Inc. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, valuation allowance for deferred tax assets, as well as pensions and retiree medical and other postretirement benefits. Certain prior year amounts have been reclassified to conform to the current year presentation.
Short-term Investments	(b) Short-term Investments Short-term investments are classified as available-for-sale
Restricted Cash and Short-term Investments	(c) Restricted Cash and Short-term Investments We have restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations.
Aircraft Fuel, Spare Parts, and Supplies, Net	(d) Aircraft Fuel, Spare Parts, and Supplies, Net Aircraft fuel is recorded on a first-in, first-out
Operating Property and Equipment	(e) Operating Property and Equipment Operating property and equipment is recorded at cost and depreciated or amortized to residual values over the asset’s estimated useful life or the lease term, whichever is less, using the straight-line method. Residual values for aircraft, engines, and related rotable parts are generally 5% to 10% of original cost. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated or amortized over the estimated useful life of the asset or the lease term, whichever is less. The estimated useful lives for the principal property and equipment classifications are as follows: Principal Property and Equipment Classification Estimated Useful Life Aircraft, engines and related rotable parts 20 – 30 years Buildings and improvements Lesser of 5 – 30 years Furniture, fixtures and other equipment 3 – 10 years Capitalized software 5 – 10 years We record impairment charges on operating property and equipment when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the assets are less than the carrying amount of the assets and the net book value of the assets exceeds their estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell.
Income Taxes	(f) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes. We provide a valuation allowance for our deferred tax assets when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our projections of future profitability, including risks associated with remaining Merger integration activities as well as other conditions which are beyond our control, such as the health of the economy, the level and volatility of fuel prices and travel demand.
Goodwill	(g) Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired and liabilities assumed. Goodwill is not amortized but assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that goodwill may be impaired. We have one consolidated reporting unit. Goodwill is measured for impairment by initially performing a qualitative assessment and, if necessary, then comparing the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is less than the carrying value, a second step is performed to determine the implied fair value of goodwill. If the implied fair value of goodwill is lower than its carrying value, an impairment charge equal to the difference is recorded. Based upon our annual assessment, there was no goodwill impairment in 2016. The carrying value of the goodwill on our consolidated balance sheets was $4.1 billion as of December 31, 2016 and 2015.
Other Intangibles, Net	(h) Other Intangibles, Net Intangible assets consist primarily of domestic airport slots, customer relationships, marketing agreements, international slots and route authorities, airport gate leasehold rights and tradenames. Finite-Lived Intangible Assets Finite-lived intangible assets are amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The following table provides information relating to our amortizable intangible assets as of December 31, 2016 and 2015 (in millions): December 31, 2016 2015 Domestic airport slots $ 365 $ 365 Customer relationships 300 300 Marketing agreements 105 105 Tradenames 35 35 Airport gate leasehold rights 137 137 Accumulated amortization (578 ) (502 ) Total $ 364 $ 440 Certain domestic airport slots and airport gate leasehold rights are amortized on a straight-line basis over 25 years. The customer relationships and marketing agreements were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately nine years and 30 years, respectively. Tradenames are fully amortized. We recorded amortization expense related to these intangible assets of $76 million, $55 million and $81 million for the years ended December 31, 2016, 2015 and 2014, respectively. We expect to record annual amortization expense for these intangible assets as follows (in millions): 2017 $ 45 2018 41 2019 41 2020 41 2021 41 2022 and thereafter 155 Total $ 364 Indefinite-Lived Intangible Assets Indefinite-lived intangible assets include certain domestic airport slots at our hubs and international slots and route authorities. Indefinite-lived intangible assets are not amortized but instead are assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2016 and 2015, we had $1.8 billion of indefinite-lived intangible assets on our consolidated balance sheets. Indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative assessment to determine whether we believe it is more likely than not that an asset has been impaired. If we believe impairment has occurred, we then evaluate for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon our annual assessment, there was no indefinite-lived intangible asset impairment in 2016.
Loyalty Program	(i) Loyalty Program We currently operate the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any one co-branded We use the incremental cost method to account for the portion of our loyalty program liability incurred when AAdvantage members earn mileage credits by flying on American, any one The incremental cost liability includes all mileage credits, even mileage credits for members whose account balances have not yet reached the minimum level required to redeem an award. Mileage credits are subject to expiration. The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. The estimated incremental cost primarily includes unit costs incurred for fuel, food and insurance as well as fees incurred when travel awards are redeemed on partner airlines. In calculating the liability, we estimate how many mileage credits will never be redeemed for travel and exclude those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These costs and estimates are based on our historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the consolidated statements of operations as a part of passenger revenue. As of December 31, 2016 and 2015, the liability for outstanding mileage credits accounted for under the incremental cost method was $669 million and $657 million, respectively, and is included on the consolidated balance sheets within loyalty program liability. Additionally, we applied the acquisition method of accounting in connection with the Merger in December 2013 and recorded a liability for outstanding US Airways’ mileage credits at fair value, an amount significantly in excess of incremental cost. At December 31, 2016, all the mileage credits associated with this liability have been recognized in passenger revenue. At December 31, 2015, this liability was $296 million and was included on the consolidated balance sheet within the loyalty program liability. We also sell loyalty program mileage credits to participating airline partners and non-airline non-airline non-airline No. 2009-13, In 2016, American entered into new co-branded co-branded The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and is amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel. As of December 31, 2016 and 2015, we had $2.1 billion and $1.5 billion, respectively, in deferred revenue from the sale of mileage credits recorded within loyalty program liability on our consolidated balance sheets. The services under the marketing component are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale. For the years ended December 31, 2016, 2015 and 2014, the marketing component of mileage sales and other marketing related payments included in other revenues was approximately $1.9 billion, $1.7 billion and $1.6 billion, respectively.
Revenue	(j) Revenue Passenger Revenue Passenger revenue is recognized when transportation is provided. Ticket sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on the consolidated balance sheets. The air traffic liability represents tickets sold for future travel dates and estimated future refunds and exchanges of tickets sold for past travel dates. The balance in the air traffic liability fluctuates throughout the year based on seasonal travel patterns and fare sale activity. Our air traffic liability was $3.9 billion and $3.7 billion as of December 31, 2016 and 2015, respectively. The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. Due to complex pricing structures, refund and exchange policies, and interline agreements with other airlines, certain amounts are recognized in passenger revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized. These estimates are generally based on the analysis of our historical data. We and other airline industry participants have consistently applied this accounting method to estimate revenue from forfeited tickets at the date of travel. Estimated future refunds and exchanges included in the air traffic liability are routinely evaluated based on subsequent activity to validate the accuracy of our estimates. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed. We have arrangements with regional carriers to provide us with regional jet and turboprop service under the brand name “American Eagle.” The American Eagle carriers include our wholly-owned regional carriers, Envoy, PSA and Piedmont, as well as third-party regional carriers including Republic Airline Inc. (Republic), Mesa Airlines, Inc. (Mesa), Air Wisconsin Airlines Corporation (Air Wisconsin), Compass Airlines, LLC (Compass), ExpressJet Airlines, Inc. (ExpressJet), SkyWest Airlines, Inc. (SkyWest) and Trans States Airlines, Inc. (Trans States). We classify revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by us for travel on these air carriers is also included in our air traffic liability and are subsequently recognized as revenue in the same manner as described above. Passenger Taxes and Fees Various taxes and fees assessed on the sale of tickets to end customers are collected by us as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority. Cargo Revenue Cargo revenue is recognized when we provide the transportation. Other Revenue Other revenue includes revenue associated with marketing services provided to our business partners as part of our loyalty program, baggage fees, ticketing change fees, airport clubs and inflight services. The accounting and recognition for the loyalty program marketing services are discussed in Note 1(i) above. Baggage fees, ticketing change fees, airport clubs and inflight service revenues are recognized when we provide the service.
Maintenance, Materials and Repairs	(k) Maintenance, Materials and Repairs Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists.
Selling Expenses	(l) Selling Expenses Selling expenses include credit card fees, commissions, computerized reservations systems fees and advertising. Advertising costs are expensed as incurred. Advertising expense was $116 million, $110 million and $92 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Share-based Compensation	(m) Share-based Compensation We account for our share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The fair value of stock options and stock appreciation rights (SARs) is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units (RSUs) is based on the market price of the underlying shares of common stock on the date of grant. See Note 14 for further discussion of share-based compensation.
Deferred Gains and Credits, Net	(n) Deferred Gains and Credits, Net Included within deferred gains and credits, net are amounts deferred and amortized into future periods associated with the adjustment of leases to fair value in connection with the application of acquisition accounting, deferred gains on the sale-leaseback of aircraft and certain vendor incentives. We periodically receive vendor incentives in connection with acquisition of aircraft and engines. These credits are deferred until aircraft and engines are delivered and then applied as a reduction to the cost of the related equipment.
Foreign Currency Gains and Losses	(o) Foreign Currency Gains and Losses Foreign currency gains and losses are recorded as part of other nonoperating expense, net in our consolidated statements of operations. Foreign currency gains for 2016 were $1 million. Foreign currency losses for 2015 and 2014 were $751 million and $114 million, respectively. Included in 2015 was a $592 million nonoperating special charge to write off all of the value of Venezuelan bolivars held by us due to continued lack of repatriations and deterioration of economic conditions in Venezuela.

Recent Accounting Pronouncements	(r) Recent Accounting Pronouncements Revenue In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, 2014-09 We are still in the process of evaluating how the adoption of the new revenue standard will impact our consolidated financial statements. We currently expect that the new revenue standard will materially impact our liability for outstanding mileage credits earned by AAdvantage loyalty program members when flying on American. We currently use the incremental cost method to account for this portion of our loyalty program liability, which values these mileage credits based on the estimated incremental cost of carrying one additional passenger (see (i) Loyalty Program above). The new revenue standard will require us to change our policy and apply a relative selling price approach whereby a portion of each passenger ticket sale attributable to mileage credits earned will be deferred and recognized in passenger revenue upon future mileage redemption. The carrying value of the earned mileage credits recognized in loyalty program liability is expected to be materially greater under the relative selling price approach than the value attributed to these mileage credits under the incremental cost method. The new revenue standard will also require us to reclassify certain ancillary fees to passenger revenue, which are currently included within other operating revenue.

American Airlines, Inc. [Member]
Basis of Presentation	(a) Basis of Presentation American Airlines, Inc. (American) is a Delaware corporation whose primary business activity is the operation of a major network air carrier. American is a wholly-owned subsidiary of American Airlines Group Inc. (AAG), which owns all of American’s outstanding common stock, par value $1.00 per share. On December 9, 2013, a subsidiary of AMR merged with and into US Airways Group, Inc. (US Airways Group), a Delaware corporation, which survived as a wholly-owned subsidiary of AAG, and AAG emerged from Chapter 11 (the Merger). Upon closing of the Merger and emergence from Chapter 11, AMR changed its name to American Airlines Group Inc. On December 30, 2015, in order to simplify AAG’s internal corporate structure, US Airways, Inc. (US Airways), a wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, valuation allowance for deferred tax assets, as well as pensions and retiree medical and other postretirement benefits. Certain prior year amounts have been reclassified to conform to the current year presentation.
Short-term Investments	(b) Short-term Investments Short-term investments are classified as available-for-sale
Restricted Cash and Short-term Investments	(c) Restricted Cash and Short-term Investments American has restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations.
Aircraft Fuel, Spare Parts, and Supplies, Net	(d) Aircraft Fuel, Spare Parts, and Supplies, Net Aircraft fuel is recorded on a first-in, first-out
Operating Property and Equipment	(e) Operating Property and Equipment Operating property and equipment is recorded at cost and depreciated or amortized to residual values over the asset’s estimated useful life or the lease term, whichever is less, using the straight-line method. Residual values for aircraft, engines, and related rotable parts are generally 5% to 10% of original cost. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated or amortized over the estimated useful life of the asset or the lease term, whichever is less. The estimated useful lives for the principal property and equipment classifications are as follows: Principal Property and Equipment Classification Estimated Useful Life Aircraft, engines and related rotable parts 20 – 30 years Buildings and improvements Lesser of 5 - 30 years Furniture, fixtures and other equipment 3 - 10 years Capitalized software 5 - 10 years American records impairment charges on operating property and equipment when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the assets are less than the carrying amount of the assets and the net book value of the assets exceeds their estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell.
Income Taxes	(f) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes. American provides a valuation allowance for its deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. American considers all available positive and negative evidence and makes certain assumptions in evaluating the realizability of its deferred tax assets. Many factors are considered that impact American’s projections of future profitability, including risks associated with remaining Merger integration activities as well as other conditions which are beyond American’s control, such as the health of the economy, the level and volatility of fuel prices and travel demand.
Goodwill	(g) Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired and liabilities assumed. Goodwill is not amortized but assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that goodwill may be impaired. American has one consolidated reporting unit. Goodwill is measured for impairment by initially performing a qualitative assessment and, if necessary, then comparing the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is less than the carrying value, a second step is performed to determine the implied fair value of goodwill. If the implied fair value of goodwill is lower than its carrying value, an impairment charge equal to the difference is recorded. Based upon American’s annual assessment, there was no goodwill impairment in 2016. The carrying value of the goodwill on American’s consolidated balance sheets was $4.1 billion as of December 31, 2016 and 2015.
Other Intangibles, Net	(h) Other Intangibles, Net Intangible assets consist primarily of domestic airport slots, customer relationships, marketing agreements, international slots and route authorities, airport gate leasehold rights and tradenames. Finite-Lived Intangible Assets Finite-lived intangible assets are amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The following table provides information relating to American’s amortizable intangible assets as of December 31, 2016 and 2015 (in millions): December 31, 2016 2015 Domestic airport slots $ 365 $ 365 Customer relationships 300 300 Marketing agreements 105 105 Tradenames 35 35 Airport gate leasehold rights 137 137 Accumulated amortization (578 ) (502 ) Total $ 364 $ 440 Certain domestic airport slots and airport gate leasehold rights are amortized on a straight-line basis over 25 years. The customer relationships and marketing agreements were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately nine years and 30 years, respectively. Tradenames are fully amortized. American recorded amortization expense related to these intangible assets of $76 million, $55 million and $81 million for the years ended December 31, 2016, 2015 and 2014, respectively. American expects to record annual amortization expense for these intangible assets as follows (in millions): 2017 $ 45 2018 41 2019 41 2020 41 2021 41 2022 and thereafter 155 Total $ 364 Indefinite-Lived Intangible Assets Indefinite-lived intangible assets include certain domestic airport slots at American’s hubs and international slots and route authorities. Indefinite-lived intangible assets are not amortized but instead are assessed for impairment annually on October 1 st or more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2016 and 2015, American had $1.8 billion of indefinite-lived intangible assets on its consolidated balance sheets. Indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative assessment to determine whether American believes it is more likely than not that an asset has been impaired. If American believes impairment has occurred, American then evaluates for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon American’s annual assessment, there was no indefinite-lived intangible asset impairment in 2016.
Loyalty Program	(i) Loyalty Program American currently operates the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any one co-branded American uses the incremental cost method to account for the portion of its loyalty program liability incurred when AAdvantage members earn mileage credits by flying on American, any one The incremental cost liability includes all mileage credits, even mileage credits for members whose account balances have not yet reached the minimum level required to redeem an award. Mileage credits are subject to expiration. The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. The estimated incremental cost primarily includes unit costs incurred for fuel, food and insurance as well as fees incurred when travel awards are redeemed on partner airlines. In calculating the liability, American estimates how many mileage credits will never be redeemed for travel and excludes those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These costs and estimates are based on American’s historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the consolidated statements of operations as a part of passenger revenue. As of December 31, 2016 and 2015, the liability for outstanding mileage credits accounted for under the incremental cost method was $669 million and $657 million, respectively, and is included on the consolidated balance sheets within loyalty program liability. Additionally, American applied the acquisition method of accounting in connection with AAG’s Merger in December 2013 and recorded a liability for outstanding US Airways’ mileage credits at fair value, an amount significantly in excess of incremental cost. At December 31, 2016, all the mileage credits associated with this liability have been recognized in passenger revenue. At December 31, 2015, this liability was $296 million and was included on the consolidated balance sheet within the loyalty program liability. American also sells loyalty program mileage credits to participating airline partners and non-airline non-airline non-airline No. 2009-13, In 2016, American entered into new co-branded co-branded The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and is amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel. As of December 31, 2016 and 2015, American had $2.1 billion and $1.5 billion, respectively, in deferred revenue from the sale of mileage credits recorded within loyalty program liability on its consolidated balance sheets. The services under the marketing component are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale. For the years ended December 31, 2016, 2015 and 2014, the marketing component of mileage sales and other marketing related payments included in other revenues was approximately $1.9 billion, $1.7 billion and $1.6 billion, respectively.
Revenue	(j) Revenue Passenger Revenue Passenger revenue is recognized when transportation is provided. Ticket sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on the consolidated balance sheets. The air traffic liability represents tickets sold for future travel dates and estimated future refunds and exchanges of tickets sold for past travel dates. The balance in the air traffic liability fluctuates throughout the year based on seasonal travel patterns and fare sale activity. American’s air traffic liability was $3.9 billion and $3.7 billion as of December 31, 2016 and 2015, respectively. The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. Due to complex pricing structures, refund and exchange policies, and interline agreements with other airlines, certain amounts are recognized in passenger revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized. These estimates are generally based on the analysis of American’s historical data. American and other airline industry participants have consistently applied this accounting method to estimate revenue from forfeited tickets at the date of travel. Estimated future refunds and exchanges included in the air traffic liability are routinely evaluated based on subsequent activity to validate the accuracy of American’s estimates. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed. American has arrangements with regional carriers to provide it with regional jet and turboprop service under the brand name “American Eagle.” The American Eagle carriers include AAG’s wholly-owned regional carriers, Envoy, PSA and Piedmont, as well as third-party regional carriers including Republic Airline Inc. (Republic), Mesa Airlines, Inc. (Mesa), Air Wisconsin Airlines Corporation (Air Wisconsin), Compass Airlines, LLC (Compass), ExpressJet Airlines, Inc. (ExpressJet), SkyWest Airlines, Inc. (SkyWest) and Trans States Airlines, Inc. (Trans States). American classifies revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by American for travel on these air carriers are also included in American’s air traffic liability and are subsequently recognized as revenue in the same manner as described above. Passenger Taxes and Fees Various taxes and fees assessed on the sale of tickets to end customers are collected by American as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority. Cargo Revenue Cargo revenue is recognized when American provides the transportation. Other Revenue Other revenue includes revenue associated with marketing services provided to American’s business partners as part of its loyalty program, baggage fees, ticketing change fees, airport clubs and inflight services. The accounting and recognition for the loyalty program marketing services are discussed in Note 1(i) above. Baggage fees, ticketing change fees, airport clubs and inflight service revenues are recognized when American provides the service.
Maintenance, Materials and Repairs	(k) Maintenance, Materials and Repairs Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists.
Selling Expenses	(l) Selling Expenses Selling expenses include credit card fees, commissions, computerized reservations systems fees and advertising. Advertising costs are expensed as incurred. Advertising expense was $116 million, $110 million and $92 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Share-based Compensation	(m) Share-based Compensation American accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The fair value of stock options and stock appreciation rights (SARs) is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units (RSUs) is based on the market price of the underlying shares of common stock on the date of grant. See Note 12 for further discussion of share-based compensation.
Deferred Gains and Credits, Net	(n) Deferred Gains and Credits, Net Included within deferred gains and credits, net are amounts deferred and amortized into future periods associated with the adjustment of leases to fair value in connection with the application of acquisition accounting, deferred gains on the sale-leaseback of aircraft and certain vendor incentives. American periodically receives vendor incentives in connection with acquisition of aircraft and engines. These credits are deferred until aircraft and engines are delivered and then applied as a reduction to the cost of the related equipment.
Foreign Currency Gains and Losses	(o) Foreign Currency Gains and Losses Foreign currency gains and losses are recorded as part of other nonoperating expense, net in American’s consolidated statements of operations. Foreign currency gains for 2016 were $1 million. Foreign currency losses for 2015 and 2014 were $751 million and $114 million, respectively. Included in 2015 was a $592 million nonoperating special charge to write off all of the value of Venezuelan bolivars held by American due to continued lack of repatriations and deterioration of economic conditions in Venezuela.
Other Operating Expenses	(p) Other Operating Expenses Other operating expenses includes costs associated with ground and cargo handling, crew travel, aircraft food and catering, passenger accommodation, airport security, international navigation fees and certain general and administrative expenses.
Regional Expenses	(q) Regional Expenses Expenses associated with American’s third-party regional carriers operating under the brand name American Eagle are classified as regional expenses on the consolidated statements of operations. Regional expenses consist of the following (in millions): Year Ended December 31, 2016 2015 2014 Aircraft fuel and related taxes $ 1,109 $ 1,230 $ 2,009 Salaries, wages and benefits 327 276 228 Capacity purchases from third-party regional carriers (1) 3,186 3,137 2,858 Maintenance, materials and repairs 4 4 6 Other rent and landing fees 487 434 386 Aircraft rent 28 28 27 Selling expenses 347 333 307 Depreciation and amortization 237 197 168 Special items, net 13 18 5 Other 271 295 483 Total regional expenses $ 6,009 $ 5,952 $ 6,477 (1) For the years ended December 31, 2016, 2015 and 2014, the component of capacity purchase expenses related to aircraft deemed to be leased was approximately $405 million, $492 million and $447 million, respectively.
Recent Accounting Pronouncements	(r) Recent Accounting Pronouncements Revenue In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, 2014-09 American is still in the process of evaluating how the adoption of the new revenue standard will impact its consolidated financial statements. American currently expects that the new revenue standard will materially impact its liability for outstanding mileage credits earned by AAdvantage loyalty program members when flying on American. American currently uses the incremental cost method to account for this portion of its loyalty program liability, which values these mileage credits based on the estimated incremental cost of carrying one additional passenger (see (i) Loyalty Program above). The new revenue standard will require American to change its policy and apply a relative selling price approach whereby a portion of each passenger ticket sale attributable to mileage credits earned will be deferred and recognized in passenger revenue upon future mileage redemption. The carrying value of the earned mileage credits recognized in loyalty program liability is expected to be materially greater under the relative selling price approach than the value attributed to these mileage credits under the incremental cost method. The new revenue standard will also require American to reclassify certain ancillary fees to passenger revenue, which are currently included within other operating revenue.

Thus, the diluted shares include the weighted average impact of the 7.25% convertible senior notes only for the period from January 1, 2014 to March 12, 2014. In addition, under GAAP, we must adjust the numerator for purposes of calculating diluted EPS by the change in fair value of the conversion feature from March 12, 2014 to May 15, 2014, which increased GAAP net income for purposes of computing diluted EPS by $3 million for the year ended December 31, 2014.
