Reorganizations [Abstract]

Reorganization

1. Chapter 11 Reorganization

Overview

On November 29, 2011 (the Petition Date) AMR, American, AMR’s principal subsidiary, and certain of American and AMR’s direct and indirect domestic subsidiaries (collectively, the Debtors) filed voluntary petitions for relief (the Chapter 11 Cases) under Chapter 11 of the United States Bankruptcy Code (the Bankruptcy Code), in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). The Chapter 11 Cases are being jointly administered under the caption “In re AMR Corporation, et al, Case No. 11-15463-SHL.”

The Company and the other Debtors are operating as “debtors in possession” under the jurisdiction of the Bankruptcy Court and the applicable provisions of the Bankruptcy Code. In general, as debtors in possession under the Bankruptcy Code, we are authorized to continue to operate as an ongoing business but may not engage in transactions outside the ordinary course of business without the prior approval of the Bankruptcy Court. The Bankruptcy Code enables the Company to continue to operate its business without interruption, and the Bankruptcy Court has granted additional relief covering, among other things, obligations to (i) employees, (ii) taxing authorities, (iii) insurance providers, (iv) independent contractors for improvement projects, (v) foreign vendors, (vi) other airlines pursuant to certain interline agreements, and (vii) certain vendors deemed critical to the Debtors’ operations.

While operating as debtors in possession under Chapter 11 of the Bankruptcy Code, the Debtors may sell or otherwise dispose of or liquidate assets or settle liabilities, subject to the approval of the Bankruptcy Court or otherwise as permitted in the ordinary course of business. The Debtors have not yet prepared or filed with the Bankruptcy Court a plan of reorganization. The Debtors have the exclusive right to file a plan of reorganization through and including April 15, 2013, subject to the ability of third parties to file motions to terminate the Debtors' exclusivity period. If the Debtors file a plan of reorganization on or prior to such date, the Debtors will have an exclusive period to solicit and obtain acceptances for such plan through and including June 17, 2013. The Debtors have the right to seek further extensions of such exclusivity periods, subject to a statutory limit of 18 months from the Petition Date in the case of filing a plan of reorganization, and 20 months from the Petition Date in the case of soliciting and obtaining acceptances. The ultimate plan of reorganization, which would be subject to acceptance by the requisite majorities of empowered creditors under the Bankruptcy Code and approval by the Bankruptcy Court, could materially change the amounts and classifications in the consolidated financial statements.

The Company’s Chapter 11 Cases followed an extended effort by the Company to restructure its business to strengthen its competitive and financial position. However, the Company’s substantial cost disadvantage compared to its larger competitors, all of which restructured their costs and debt through Chapter 11, became increasingly untenable given the accelerating impact of global economic uncertainty and resulting revenue instability, volatile and rising fuel prices, and intensifying competitive challenges.

No assurance can be given as to the value, if any, that may be ascribed to the Debtors’ various prepetition liabilities and other securities. The Company cannot predict what the ultimate value of any of its or the other Debtors' securities may be.

General Information

Notices to Creditors; Effect of Automatic Stay. The Debtors have notified all known current or potential creditors that the Chapter 11 Cases were filed. Subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors’ Chapter 11 Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date. Thus, for example, most creditor actions to obtain possession of property from the Debtors, or to create, perfect or enforce any lien against the property of the Debtors, or to collect on monies owed or otherwise exercise rights or remedies with respect to a prepetition claim, are enjoined unless and until the Bankruptcy Court lifts the automatic stay as to any such claim. Vendors are being paid for goods furnished and services provided after the Petition Date in the ordinary course of business.

Appointment of Creditors’ Committee. On December 5, 2011, the U.S. Trustee appointed the Creditors’ Committee (Creditors' Committee) for the Chapter 11 Cases.

Retirement and Life Insurance Benefits. See Note 11 to the consolidated financial statements for information regarding modifications to retirement and life insurance benefits.

Rejection of Executory Contracts. Under section 365 and other relevant sections of the Bankruptcy Code, the Debtors may assume, assume and assign, or reject certain executory contracts and unexpired leases, including, without limitation, agreements relating to aircraft and aircraft engines (collectively, Aircraft Property) and leases of real property, subject to the approval of the Bankruptcy

Court and certain other conditions. As of December 31, 2012, the Bankruptcy Court had entered orders granting the Debtors' motions to assume 526 and reject 10 unexpired leases of non-residential real property and had entered various orders extending, by the Debtors' agreement with certain landlords, the date by which the Debtors must assume or reject an additional 37 unexpired leases of non-residential real property. As of December 31, 2012, the Company had also entered into stipulations or agreed orders providing that the claims with respect to special facility revenue bonds at Dallas/Fort Worth International Airport, Fort Worth Alliance Airport and Luis Muñoz Marín International Airport in San Juan, Puerto Rico were general unsecured claims.

In general, rejection of an executory contract or unexpired lease is treated as a prepetition breach of the executory contract or unexpired lease in question and, subject to certain exceptions, relieves the Debtors from performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a prepetition general unsecured claim for damages caused by such deemed breach. Counterparties to such rejected contracts or leases have the right to file claims against the Debtors’ estate for such damages. Generally, the assumption of an executory contract or unexpired lease requires the Debtors to cure existing defaults under such executory contract or unexpired lease.

Any description of an executory contract or unexpired lease elsewhere in these Notes or in the report to which these Notes are attached, including where applicable the Debtors’ express termination rights or a quantification of their obligations, must be read in conjunction with, and is qualified by, any rights the Debtors or counterparties have under section 365 of the Bankruptcy Code.

The Debtors expect that liabilities subject to compromise and resolution in the Chapter 11 Cases will arise in the future as a result of damage claims created by the Debtors’ rejection of various executory contracts and unexpired leases. Due to the uncertain nature of many of the potential rejection claims, the magnitude of such claims is not reasonably estimable at this time. Such claims may be material (see “Liabilities Subject to Compromise” in Note 1 to the consolidated financial statements).

Special Protection Applicable to Leases and Secured Financing of Aircraft and Aircraft Equipment. Notwithstanding the general discussion above of the impact of the automatic stay, under section 1110 of the Bankruptcy Code, beginning 60 days after filing a petition under Chapter 11, certain secured parties, lessors and conditional sales vendors may have a right to take possession of certain qualifying Aircraft Property that is leased or subject to a security interest or conditional sale contract, unless the Debtors, subject to approval by the Bankruptcy Court, agree to perform under the applicable agreement, and cure any defaults as provided in section 1110 (other than defaults of a kind specified in section 365(b)(2) of the Bankruptcy Code). Taking such action does not preclude the Debtors from later rejecting the applicable lease or abandoning the Aircraft Property subject to the related security agreement, or from later seeking to renegotiate the terms of the related financing.

The Debtors may extend the 60-day period by agreement of the relevant financing party, with Bankruptcy Court approval. In the absence of an agreement or cure as described above or such an extension, the financing party may take possession of the Aircraft Property and enforce its contractual rights or remedies to sell, lease or otherwise retain or dispose of such equipment.

The 60-day period under section 1110 in the Chapter 11 Cases expired on January 27, 2012. In accordance with the Bankruptcy Court’s Order Authorizing the Debtors to (i) Enter into Agreements Under Section 1110(a) of the Bankruptcy Code, (ii) Enter into Stipulations to Extend the Time to Comply with Section 1110 of the Bankruptcy Code and (iii) File Redacted Section 1110(b) Stipulations, dated December 23, 2011, the Debtors have entered into agreements to extend the automatic stay or agreed to perform and cure defaults under financing agreements with respect to certain aircraft in their fleet and other Aircraft Property. With respect to certain Aircraft Property, the Debtors have reached agreements on, or agreements on key aspects of, renegotiated terms of the related financings, and the Debtors are continuing to negotiate terms with respect to certain of their other Aircraft Property financings. The ultimate outcome of these negotiations cannot be predicted with certainty. To the extent the Debtors are unable to reach definitive agreements with Aircraft Property financing parties, those parties may seek to repossess the subject Aircraft Property. The loss of a significant number of aircraft could result in a material adverse effect on the Debtors’ financial and operating performance.

In accordance with section 1110 of the Bankruptcy Code, as of December 31, 2012, the Company had (i) rejected 40 leases relating to 21 MD-80 aircraft, four Fokker 100 aircraft, seven Boeing 757-200 aircraft and eight spare engines; (ii) relinquished one Airbus A300-600R aircraft that was subject to a mortgage; and (iii) made elections under section 1110(a) of the Bankruptcy Code to retain 340 aircraft and 87 spare engines, including Boeing 737-800, Boeing 757-200, Boeing 767-300ER, Boeing 777-200ER, Bombardier CRJ-700, and McDonnell Douglas MD-80 aircraft, on the terms provided in the related financing documents. In addition, as of December 31, 2012, the Company had reached agreement on revised economic terms of the financings of 155 aircraft, comprising 83 MD-80 aircraft, nine Boeing 737-800 aircraft, 36 Boeing 757-200 aircraft, 11 Boeing 767-200ER aircraft, 13 Boeing 767-300ER aircraft and three Boeing 777-200ER aircraft (which agreements are subject to certain conditions, including reaching agreement on definitive documentation). Those 155 aircraft are substantially all of the mainline aircraft in the Company's fleet for which it expects to negotiate revised economic terms in the Chapter 11 Cases. In addition, the Company reached an agreement with the lessor to modify the leases of 39 Super ATR aircraft. As of December 31, 2012, 30 of the Super ATR aircraft had been returned to the lessor as allowed under the modified agreement. The remaining 9 Super ATR aircraft are expected to be returned to the

lessor in 2013.

Lastly, the Company entered into a series of agreements with the lender with respect to its 216 Embraer RJ aircraft and certain other interested parties pursuant to which the Company (i) surrendered 18 Embraer RJ 135 aircraft on June 21, 2012, (ii) subject to certain conditions (including reaching agreement on definitive documentation), will restructure the mortgage debt encumbering 59 Embraer 140 aircraft and 68 Embraer 145 aircraft and (iii) transferred and leased back its remaining 21 Embraer RJ 135 aircraft. The debt encumbering 50 Embraer 145 aircraft will not be reduced. The Company's entry into these transactions was approved by the Bankruptcy Court on November 8, 2012.

Magnitude of Potential Claims. On February 27, 2012, the Debtors filed with the Bankruptcy Court schedules and statements of financial affairs setting forth, among other things, the assets and liabilities of the Debtors, subject to the assumptions filed in connection therewith. All of the schedules are subject to further amendment or modification.

Bankruptcy Rule 3003(c)(3) requires the Bankruptcy Court to fix the time within which proofs of claim must be filed in a Chapter 11 case pursuant to section 501 of the Bankruptcy Code. This Bankruptcy Rule also provides that any creditor who asserts a claim against the Debtors that arose prior to the Petition Date and whose claim (i) is not listed on the Debtors' schedules or (ii) is listed on the schedules as disputed, contingent, or unliquidated, must file a proof of claim. On May 4, 2012, the Bankruptcy Court entered an order that established July 16, 2012 at 5:00 p.m. (Eastern Time) as the deadline to file proofs of claim against any Debtor. More information regarding the filing of proofs of claim can be obtained at www.amrcaseinfo.com. Information on this website is not incorporated into or otherwise made a part of this report.

As of February 13, 2013, approximately 13,366 claims totaling about $290.0 billion have been filed with the Bankruptcy Court against the Debtors. Of those claims, approximately 350 claims aggregating approximately $59 million were filed after the Bar Date. We expect new and amended claims to be filed in the future, including claims amended to assign values to claims originally filed with no designated value. We have identified, and we expect to continue to identify, many claims that we believe should be disallowed by the Bankruptcy Court because they are duplicative, are without merit, are overstated or for other reasons. As of February 13, 2013, the Bankruptcy Court has disallowed approximately $100.2 billion of claims and has not yet ruled on our other objections to claims, the disputed portions of which aggregate to an additional $14.8 billion. We expect to continue to file objections in the future. Because the process of analyzing and objecting to claims is ongoing, the amount of disallowed claims may increase significantly in the future. The Debtors have recorded amounts for claims for which there was sufficient information to estimate the claim.

Differences between amounts scheduled by the Debtors and claims by creditors will be investigated and resolved in connection with the claims resolution process. In light of the expected number of creditors, the claims resolution process may take considerable time to complete. Accordingly, the ultimate number and amount of allowed claims is not presently known, nor can the ultimate recovery with respect to allowed claims be presently ascertained.

Collective Bargaining Agreements. The Bankruptcy Code provides a process for the modification and/or rejection of collective bargaining agreements (CBAs). In particular, section 1113(c) of the Bankruptcy Code permits a debtor to reject its CBAs if the debtor satisfies a number of statutorily prescribed substantive and procedural prerequisites and obtains the Bankruptcy Court's approval to reject the CBAs. The section 1113(c) process requires that a debtor must make proposals to its unions to modify existing CBAs based on the most complete and reliable information available at the time the proposals are made. The proposed modifications must be necessary to permit the reorganization of the debtor and must assure that all the affected parties are treated fairly and equitably. The debtor must provide the unions with all information necessary to evaluate the proposals, and meet at reasonable times and confer in good faith with the unions in an effort to reach mutually agreeable modifications to the CBAs. American commenced the section 1113(c) process with its unions (APA, APFA and TWU) on February 1, 2012, and negotiated in good faith with the unions for consensual agreements that achieve the necessary level of labor cost savings. Because consensual agreements had not been reached, and given American's need to restructure its labor costs expeditiously, the Debtors filed a motion with the Bankruptcy Court on March 27, 2012 requesting approval to reject the CBAs.

The Court hearing on the Debtors' request to reject the CBAs began on April 23, 2012 and concluded the week of May 21, 2012. After the filing of its request to reject its CBAs, American and the unions continued to negotiate in good faith toward consensual agreements. Those negotiations resulted in ratified agreements with all seven TWU-represented groups (Fleet Service Clerks, Dispatchers, Ground School Instructors, Maintenance Control Technicians, Simulator Technicians, Mechanics and Related (M&R), and Stores), all of which have been approved by the Bankruptcy Court. On July 20, 2012, APFA sent American's proposed Last Best and Final Offer (LBFO) to its membership for a ratification vote, and on August 19, 2012 APFA announced the LBFO was ratified by the membership. This new agreement was approved by the Bankruptcy Court on September 12, 2012. Having secured Court approval of the APFA and all seven TWU agreements, American has begun implementing the terms of all of its new agreements.

In August 2012, APA announced that its membership did not ratify a tentative agreement reached by the parties in June. Following its initial decision denying American's request to reject the APA CBA, the Bankruptcy Court granted American's renewed motion to reject that agreement and entered an order on September 5, 2012 authorizing American to reject the pilot CBA. In accordance with the Bankruptcy Court's ruling, American began implementing certain terms and conditions of employment for pilots that the Bankruptcy Court determined were fair and necessary for the Debtors' successful restructuring. American and APA continued to negotiate in good faith toward a new pilot agreement, and on November 9, 2012, the parties reached a tentative agreement on a new comprehensive CBA. On December 7, 2012, the APA announced the tentative agreement was ratified. The new CBA was approved by the Bankruptcy Court on December 19, 2012, and American has begun implementing the terms of its new agreement with the APA. A small group of American pilots is appealing the Bankruptcy Court's decisions granting American's renewed motion to reject the pilot CBA and approving the new pilot CBA, and those appeals are pending in the U.S. District Court for the Southern District of New York.

AMR Eagle commenced the Section 1113(c) process with its unions on March 21, 2012. On July 27, 2012, AMR Eagle reached a tentative agreement with the Association of Flight Attendants. That tentative agreement was ratified by the flight attendants on September 7, 2012. On August 8, 2012, AMR Eagle reached an agreement-in-principle with the Air Line Pilots Association ("ALPA"). The ALPA Master Executive Council accepted the terms of the agreement-in-principle on September 12, 2012 and the tentative agreement was ratified by the pilot group on October 8, 2012. On July 20, 2012, AMR Eagle and the TWU reached a tentative agreement with the Mechanics and Related and Fleet Service Clerks groups. On August 24, 2012, the TWU announced that the Fleet Service Clerks group ratified its tentative agreement and that the Mechanics and Related group did not ratify its tentative agreement. Because consensual agreements had not been reached with the TWU represented Mechanics, Ground School Instructors and Dispatchers, AMR Eagle filed a motion with the Bankruptcy Court on September 7, 2012 requesting approval to reject those CBAs. AMR Eagle continued to negotiate in good faith with the TWU with respect to each of those work groups. On October 3, 2012, AMR Eagle and the TWU reached tentative agreements with the Mechanics and Related and the Ground School Instructors groups. On October 8, 2012, AMR Eagle reached a tentative agreement with the TWU represented Dispatch group. The tentative agreements for Mechanics, Ground School Instructors and Dispatchers were sent to those work groups for a ratification vote. On October 26, 2012, AMR Eagle's Mechanics and Ground School Instructors voted to ratify their tentative agreements, and the Dispatchers did not ratify their tentative agreement. A hearing on AMR Eagle’s Section 1113 motion to reject the Dispatchers CBA, originally scheduled to begin on November 14, 2012, was continued until December 10, 2012. On December 3, 2012, AMR Eagle reached a second tentative agreement with the TWU represented Dispatchers and the membership ratified the tentative agreement on December 18, 2012. All of the new AMR Eagle CBAs were approved by the Bankruptcy Court on December 21, 2012. AMR Eagle has begun implementing the terms of all the new CBAs.

Availability and Utilization of Net Operating Losses. The availability and utilization of net operating losses (and utilization of alternative minimum tax credits) after the Debtors’ emergence from Chapter 11 is uncertain at this time and will be highly influenced by the composition of the plan of reorganization that is ultimately pursued. On January 27, 2012, the Bankruptcy Court issued a Final Order Establishing Notification Procedures for Substantial Claimholders and Equityholders and Approving Restrictions on Certain Transfers of Interests in the Debtors’ Estates, which restricts trading in AMR's common stock and establishes certain procedures and potential restrictions with respect to the transfer of claims. The order is intended to prevent certain transfers of the Company’s common stock and certain transfers of claims against the Debtors that could impair the ability of one or more of the Debtors’ estates to use their net operating loss carryovers and certain other tax attributes currently or on a reorganized basis. Any acquisition, disposition, or other transfer of equity or claims on or after November 29, 2011 in violation of the restrictions set forth in the order will be null and void ab initio and/or subject to sanctions as an act in violation of the automatic stay under sections 105(a) and 362 of the Bankruptcy Code. The order applies to (i) “Substantial Equityholders,” i.e., persons who are, or as a result of a transaction would become, the beneficial owner of approximately 4.5 percent of the outstanding shares of the Company’s common stock and (ii) “Substantial Claimholders,” i.e., persons who are, or as a result of a transaction become, the beneficial owner of unsecured claims in excess of a threshold amount of unsecured claims (initially $190 million of unsecured claims, but which may be subsequently increased or decreased under certain circumstances in connection with the Debtors’ filing of a Chapter 11 plan). In the case of Substantial Equityholders, the order imposes current restrictions with respect to the acquisition or disposition of the Company’s stock, and certain notifications may be required. In the case of Substantial Claimholders, the order imposes a procedure pursuant to which, under certain circumstances, the claims acquired during the Chapter 11 Cases may have to be resold, and certain notifications may be required. The Merger Agreement provides that the procedures of the order, as in effect or as amended with the reasonable approval of US Airways, will be used to obtain ownership information from Substantial Claimholders. See discussion in Item 1A, "Risk Factors - Chapter 11 Reorganization Risks" regarding the potential impact of these rules on the company's utilization of its net operating losses post emergence from bankruptcy and in Item 1A, "Risk Factors - Common Stock Risks" regarding the establishing of limitations on the transfer of AMR's common stock post emergence from bankruptcy.

Liabilities Subject to Compromise

The following table summarizes the components of liabilities subject to compromise included on the Consolidated Balance Sheet

as of December 31, 2012 and 2011:



(in millions)
	2012		2011
Long-term debt	$	358	$	1,642
Estimated allowed claims on aircraft lease and debt obligations and facility lease and bond obligations	3,716		1,868
Pension and postretirement benefits	1,250		—
Accounts payable and other accrued liabilities	370		438
Other	—		4
Total liabilities subject to compromise	$	5,694	$	3,952

Long-term debt, including undersecured debt, classified as subject to compromise as of December 31, 2012 and 2011 consisted of (in millions):



	2012		2011
Secured variable and fixed rate indebtedness due through 2023 (effective rates from 1.00%-13.00% at December 31, 2012)	172		1,456
6.00%—8.50% special facility revenue bonds due through 2036	186		186
	$	358	$	1,642

Liabilities subject to compromise refers to prepetition obligations which may be impacted by the Chapter 11 reorganization process. These amounts represent the Debtors’ current estimate of known or potential prepetition obligations to be resolved in connection with the Chapter 11 Cases.

In accordance with ASC 852, substantially all of the Company’s unsecured debt has been classified as liabilities subject to compromise. Additionally, certain of the Company’s undersecured debt instruments have also been classified as liabilities subject to compromise.

As a result of the modifications to the retirement benefits as discussed in Note 11 to the consolidated financial statements, a portion of the pension and postretirement benefits liability, primarily relating to retiree medical and other benefits, was classified as liabilities subject to compromise as of December 31, 2012.

Differences between liabilities the Debtors have estimated and the claims filed, or to be filed, will be investigated and resolved in connection with the claims resolution process. The Company will continue to evaluate these liabilities throughout the Chapter 11 Cases and adjust amounts as necessary. Such adjustments may be material. In light of the expected number of creditors, the claims resolution process may take considerable time to complete. Accordingly, the ultimate number and amount of allowed claims is not presently known.

Reorganization Items, net

Reorganization items refer to revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases. The following table summarizes the components included in reorganization items, net on the Consolidated Statements of Operations for the years ended December 31, 2012 and 2011:

to estimate the claim. Modifications of the financings related to aircraft remain subject to conditions, including reaching agreement on definitive documentation. See above, “Special Protection Applicable to Leases and Secured Financing of Aircraft and Aircraft Equipment,” for further information.

(2)

Amounts include allowed claims (claims approved by the Bankruptcy Court) and estimated allowed claims relating to entry of orders treating as unsecured claims with respect to facility agreements supporting certain issuances of special facility revenue bonds. The Debtors record an estimated claim associated with the treatment of claims with respect to facility agreements when the applicable motion is filed with the Bankruptcy Court and the Debtors believe that it is probable that the motion will be approved, and there is sufficient information to estimate the claim. See above, “Rejection of Executory Contracts,” for further information.

Claims related to reorganization items are reflected in liabilities subject to compromise on the Consolidated Balance Sheet as of December 31, 2012 and 2011.

Summary of Accounting Policies

2. Summary of Accounting Policies

Basis of Presentation The accompanying consolidated financial statements as of December 31, 2012 and for the three years ended December 31, 2012 include the accounts of AMR and its wholly owned subsidiaries, including (i) its principal subsidiary, American Airlines, Inc. (American) and (ii) its regional airline subsidiary, AMR Eagle Holding Corporation (AMR Eagle), which has two primary subsidiaries, American Eagle Airlines, Inc. and Executive Airlines, Inc. . The consolidated financial statements as of and for the years ended December 31, 2012, 2011 and 2010 include the accounts of the Company and its wholly owned subsidiaries as well as variable interest entities (VIEs) for which the Company is the primary beneficiary. All significant intercompany transactions have been eliminated.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP), including the provisions of ASC 852 “Reorganizations” (ASC 852). ASC 852 requires that the financial statements of the Company, for periods subsequent to the filing of the Chapter 11 Cases, distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases are recorded in reorganization items, net on the accompanying Consolidated Statement of Operations. In addition, prepetition obligations that may be impacted by the Chapter 11 reorganization process have been classified on the Consolidated Balance Sheet in liabilities subject to compromise. These liabilities are reported at the amounts expected to be allowed by the Bankruptcy Court, even if they may be settled for lesser amounts.

Certain of our non-U.S. subsidiaries are not part of the Chapter 11 Cases. Since the non-US subsidiaries not part of the bankruptcy filing do not have significant transactions, we do not separately disclose the condensed combined financial statements of such non-U.S. subsidiaries s in accordance with the requirements of reorganization accounting.

The Company has also prepared these consolidated financial statements on a going concern basis, which contemplates continuity of operations, realization of assets and satisfaction of liabilities in the ordinary course of business. Accordingly, the Company’s consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

As a result of the Chapter 11 proceedings, the satisfaction of our liabilities and funding of ongoing operations are subject to uncertainty and, accordingly, there is a substantial doubt of the Company’s ability to continue as a going concern.

The accompanying consolidated financial statements do not purport to reflect or provide for the consequences of the Chapter 11 Cases, other than as set forth under “liabilities subject to compromise” on the accompanying Consolidated Balance Sheets and “income (loss) before reorganization items, net” and “reorganization items, net” on the accompanying Consolidated Statements of Operations (see Note 1 to the consolidated financial statements). In particular, the financial statements do not purport to show (1) as to assets, their realizable value on a liquidation basis or their availability to satisfy liabilities; (2) as to prepetition liabilities, the amounts that may be allowed for claims or contingencies, or the status and priority thereof; (3) as to shareowners’ equity accounts, the effect of any changes that may be made to the Debtors' capitalization; or (4) as to operations, the effect of any changes that may be made to the Debtors' business.

While operating as debtors-in-possession under Chapter 11 of the Bankruptcy Code, the Debtors may sell or otherwise dispose of or liquidate assets or settle liabilities, subject to the approval of the Bankruptcy Court or otherwise as permitted in the ordinary course of business. Moreover, the ultimate plan of reorganization for the Debtors could materially change the amounts and classifications in the historical consolidated financial statements.

New Accounting Pronouncements In December 2011, the FASB issued ASU 2011-11, “Disclosures About Offsetting Assets and

Liabilities.” This update creates new disclosure requirements about the nature of an entity’s rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The disclosure requirements in this update are effective for annual reporting periods, and interim periods within those years, beginning on or after January 1, 2013. The Company is currently evaluating the impact this update will have on its disclosures.

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment.” This update amends ASC 350, “Intangibles—Goodwill and Other” to allow entities an option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. Under that option, an entity no longer would be required to calculate the fair value of the intangible asset unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments in this update are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company is currently evaluating the impact this update may have on its indefinite-lived intangibles impairment testing.

In August of 2012, the SEC issued a final rule implementing Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act that imposes reporting requirements on issuers who use or may use “Conflict Minerals,” defined as columbite-tantalite (the metal ore from which tantalum is extracted), cassiterite (the metal ore from which tin is extracted), gold, and wolframite (the metal ore from which tungsten is extracted), or their derivatives, originating from the Democratic Republic of the Congo and neighboring countries (collectively, “covered countries”). The rule was mandated in response to humanitarian concerns that trade in conflict minerals are used to finance armed groups in the covered countries. The rule describes assessment and reporting requirements for all issuers for which conflict minerals originating in a covered country are necessary to the functionality or production of a product manufactured, or contracted to be manufactured, by the issuer. Such issuers are required to file a newly created Form SD annually by May 31 for the prior calendar year. Initial Form SDs are required to be filed by May 31, 2014 for the calendar year 2013. The Company is currently in the process of assessing whether it will be required to file a Form SD for calendar year 2013 and determining necessary processes and procedures to collect information necessary to make any required filing. The Company does not anticipate that any requirement to file this new Form SD will have a material impact on its consolidated financial statements.

Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Restricted Cash and Short-term Investments The Company has restricted cash and short-term investments related primarily to collateral held to support projected workers’ compensation obligations and funds held for certain tax obligations.

Inventories Spare parts, materials and supplies relating to flight equipment are carried at average acquisition cost and are expensed when used in operations. Allowances for obsolescence are provided—over the estimated useful life of the related aircraft and engines—for spare parts expected to be on hand at the date aircraft are retired from service. Allowances are also provided for spare parts currently identified as excess and obsolete. These allowances are based on management estimates, which are subject to change.

Maintenance and Repair Costs 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.

Intangible Assets Route acquisition costs and airport operating and gate lease rights represent the purchase price attributable to route authorities (including international airport take-off and landing slots), domestic airport take-off and landing slots and airport gate leasehold rights acquired. Indefinite-lived intangible assets (route acquisition costs and international slots and related international take-off and landing slots) are tested for impairment annually on December 31, rather than amortized, or when a triggering event occurs, in accordance with U.S. GAAP. Such triggering events may include significant changes to the Company’s network or capacity, or the implementation of open skies agreements in countries where the Company operates flights. Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value.

Statements of Cash Flows Short-term investments, without regard to remaining maturity at acquisition, are not considered as cash equivalents for purposes of the statements of cash flows.

Measurement of Asset Impairments The Company records impairment charges on long-lived assets used in operations 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 asset are less than the carrying amount of the asset and the net book value of the asset exceeds its estimated fair value. In making these determinations, the Company uses certain assumptions, including, but not limited to: (i) estimated fair value of the asset; and (ii) estimated future cash flows expected to be generated by the asset,

which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company’s operations and estimated salvage values.

Equipment and Property The provision for depreciation of operating equipment and property is computed on the straight-line method applied to each unit of property, except that major rotable parts, avionics and assemblies are depreciated on a group basis. The depreciable lives used for the principal depreciable asset classifications are:



		Depreciable Life

American jet aircraft and engines		20 - 30 years
Other regional aircraft and engines		16 - 20 years
Major rotable parts, avionics and assemblies		Life of equipment to which applicable
Improvements to leased flight equipment		Lesser of remaining lease term or expected useful life
Buildings and improvements (principally on leased land)		5 - 30 years or term of lease, including estimated renewal options when renewal is economically compelled at key airports
Furniture, fixtures and other equipment		3 - 10 years
Capitalized software		5 - 10 years

Residual values for aircraft, engines, major rotable parts, avionics and assemblies are generally five to ten percent, except when guaranteed by a third party for a different amount.

Equipment and property under capital leases are amortized over the term of the leases or, in the case of certain aircraft, over their expected useful lives. Lease terms vary but are generally six to 25 years for aircraft and seven to 40 years for other leased equipment and property.

Regional Affiliates Revenue from ticket sales is generally recognized when service is provided. Regional Affiliates revenues for flights connecting to American flights are based on industry standard proration agreements.

Passenger Revenue Passenger ticket sales are initially recorded as a component of Air traffic liability. Revenue derived from ticket sales is recognized at the time service is provided. However, due to various factors, including the complex pricing structure and interline agreements throughout the industry, certain amounts are recognized in revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized, including breakage. These estimates are generally based upon the evaluation of historical trends, including the use of regression analysis and other methods to model the outcome of future events based on the Company’s historical experience, and are recorded at the scheduled time of departure.

Various taxes and fees assessed on the sale of tickets to end customers are collected by the Company as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statement of operations and recorded as a liability until remitted to the appropriate taxing authority.

Frequent Flyer Program The estimated incremental cost of providing free travel awards is accrued for mileage credits earned by using American’s service that are expected to be redeemed in the future. American also accrues a frequent flyer liability for the mileage credits that are expected to be used for travel on participating airlines based on historical usage patterns and contractual rates. American sells mileage credits and related services to companies participating in its frequent flyer program. The portion of the revenue related to the sale of mileage credits, representing the revenue for air transportation sold, is valued at fair value and is deferred and amortized over 28 months, which approximates the expected period over which the mileage credits are used. Breakage of sold miles is recognized over the estimated period of usage. The remaining portion of the revenue, representing the marketing services sold and administrative costs associated with operating the AAdvantage program, is recognized upon sale as a component of Other revenues, as the related services have been provided. The Company’s total liability for future AAdvantage award redemptions for free, discounted or upgraded travel on American, American Eagle or participating airlines as well as unrecognized revenue from selling AAdvantage miles was approximately $1.7 billion (and is recorded as a component of Air traffic liability on the accompanying consolidated balance sheets) at December 31, 2012 and $1.6 billion as of December 31, 2011.

Income Taxes The Company generally believes that the positions taken on previously filed income tax returns are more likely than not to be sustained by the taxing authorities. The Company has recorded income tax and related interest liabilities where the Company believes its position may not be sustained or where the full income tax benefit will not be recognized. Thus, the effects of potential income tax benefits resulting from the Company’s unrecognized tax positions are not reflected in the tax balances of the financial statements. Recognized and unrecognized tax positions are reviewed and adjusted as events occur that affect the Company’s judgment about the recognizability of income tax benefits, such as lapsing of applicable statutes of limitations, conclusion of tax audits, release of administrative guidance, or rendering of a court decision affecting a particular tax position.

Advertising Costs The Company expenses on a straight-line basis the costs of advertising as incurred throughout the year. Advertising expense was $153 million for the year ended December 31, 2012, $186 million for the year ended December 31, 2011 and $165 million for the year ended December 31, 2010.

Subsequent Events In connection with preparation of the consolidated financial statements and in accordance U.S. GAAP, the Company evaluated subsequent events after the balance sheet date of December 31, 2012 and identified items as set forth in Note 17 to the consolidated financial statements.

Special Charges and Restructuring Activities

3. Special Charges and Restructuring Activities

Employee Charges

The Company's business plan as announced on February 1, 2012 contemplates, among other things, significantly reducing the number of positions. Based on agreements reached with various workgroups we now expect to reduce a total of approximately 10,500 positions. During the second quarter, the Company commenced both voluntary and involuntary employee separations from the Company. Consequently, during 2012, the Company recorded charges of approximately $360 million for severance related costs associated with the voluntary and involuntary reductions in certain work groups. The severance charges will be paid through the end of 2013.

Aircraft Charges

In connection with the Boeing and Airbus aircraft agreements entered into by American in the second quarter of 2011, and the Company’s anticipated acceleration of its fleet renewal and replacement plan, the Company recorded an impairment charge of $713 million in 2011 to write its Boeing 757 aircraft and certain related long-lived assets down to their estimated fair values. For further information regarding the Boeing and Airbus agreements, see Note 17 to the consolidated financial statements.

In 2008 and 2009, the Company announced capacity reductions due to unprecedented high fuel costs at that time and the other challenges facing the industry. In connection with these capacity reductions, the Company incurred special charges related to aircraft and certain other charges.

The following table summarizes the components of the Company’s special charges, the remaining accruals for these charges and the capacity reduction related charges (in millions) as of December 31, 2012:



	Aircraft Charges			Facility Exit Costs			Employee Charges			Total
Remaining accrual at January 1, 2010	$	153		$	20		$	—		$	173

Remaining accrual at December 31, 2012	$	—		$	4		$	192		$	196

Cash outlays related to the accruals for facility exit costs will occur through 2017. However, these cash outlays could be modified in the Chapter 11 proceedings.

Other

As a result of the Terrorist Attacks and the subsequent liability protections provided for by the Air Transportation Safety and System Stabilization Act (the Stabilization Act), the Company recorded a liability for the 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 the Terrorist Attacks, against any air carrier shall not exceed the liability coverage maintained by the air carrier. In the second quarter of 2011, the Company received $576 million in insurance

proceeds as partial settlement of claims related to the Terrorist Attacks. The Company used these funds to pay a portion of its share of the associated liability. Reflecting this settlement, the remaining liability, and the amount of the offsetting receivable as of December 31, 2012, were each $1.1 billion.

Due after three years	545

	$	3,408

All short-term investments are classified as available-for-sale and stated at fair value. Unrealized gains and losses are reflected as a component of Accumulated other comprehensive income (loss).

The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The Company’s short-term investments classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities. The Company’s fuel derivative contracts, which consist primarily of call options, collars (consisting of a purchased call option and a sold put option) and call spreads (consisting of a purchased call option and a sold call option), are valued using energy and commodity market data which is derived by combining raw inputs with quantitative models and processes to generate forward curves and volatilities. Heating oil, jet fuel and crude oil are the primary underlying commodities in the hedge portfolio. No changes in valuation techniques or inputs occurred during the year ended December 31, 2012.

Assets and liabilities measured at fair value on a recurring basis are summarized below:

¹ Unrealized gains or losses on short-term investments, restricted cash and short-term investments and derivatives qualifying for hedge accounting are recorded in Accumulated other comprehensive income (loss) at each measurement date.

² The Company’s short-term investments mature in one year or less except for $200 million of Bank notes/Certificates of deposit/Time deposits, $545 million of U.S. Government agency investments and $405 million of Corporate obligations which have maturity dates exceeding one year.

No significant transfers between Level 1 and Level 2 occurred during the year ended December 31, 2012. The Company’s policy regarding the recording of transfers between levels is to record any such transfers at the end of the reporting period.

As of December 31, 2012, the Company had no exposure to European sovereign debt.

The assumption of certain agreements related to the Company's aircraft commitments is subject to collaboration with the Company's key stakeholders and, in some instances, approval of the Bankruptcy Court. The Company cannot predict what the outcome of these discussions and the Bankruptcy Court process will be.

As of December 31, 2012, and subject to assumption of certain of the related agreements, payments for the above purchase commitments and certain engines will approximate $2.1 billion in 2013, $1.0 billion in 2014, $314 million in 2015, $355 million in 2016, $745 million in 2017 and $6.6 billion for 2018 and beyond. These amounts are net of purchase deposits currently held by the manufacturers. American has granted Boeing a security interest in American’s purchase deposits with Boeing. The Company’s purchase deposits totaled $710 million as of December 31, 2012.

As of December 31, 2012, and subject to assumption of certain of the related agreements, total future lease payments for all leased aircraft, including aircraft not yet delivered, will approximate $727 million in 2013, $889 million in 2014, $1.1 billion in 2015, $1.4 billion in 2016, $1.6 billion in 2017 and $11.3 billion in 2018 and beyond. Certain leases provide for rent adjustments based on forumulae tied to changes in interest rates.

In February 2013, American entered into agreements with Boeing that provide for, among other things, the assumption and restructuring of certain existing aircraft purchase agreements, the entering into of a definitive purchase agreement with respect to Boeing 737 MAX aircraft, the confirmation of the purchase of the Boeing 787 aircraft (which previously had been subject to certain reconfirmation rights) and certain financing commitments. American also entered into an amendment to its agreement with Airbus S.A.S. in January 2013. The Bankruptcy Court approved assumption of these agreements, as amended, in January 2013. See Note 17 to the consolidated financial statements for further information regarding these agreements, including the changes to the Company's aircraft acquisition commitments, payments and options.

In 2010, American and Japan Airlines (JAL) entered into a Joint Business Agreement (JBA) under which, amongst other things, American provided JAL a guarantee of certain minimum incremental revenue resulting from the successful operation of the joint business for the first three years following its implementation, subject to certain terms and conditions. The amount required to be

paid by the Company under the guarantee in any one of such years may not exceed $100 million, and is reduced if capacity for one of such years is less than a defined base year period capacity. Based on current Trans-Pacific capacity, the guarantee in any one of such years may not exceed approximately $75 million. As of December 31, 2012, based on an expected probability model, American had recorded a guarantee liability that is not material.

The Company has contracts related to facility construction or improvement projects, primarily at airport locations. The contractual obligations related to these projects totaled approximately $79 million as of December 31, 2012. The Company expects to make payments on these obligations of $52 million, $10 million, and $17 million, in 2013, 2014, and 2015, respectively. In addition, the Company has an information technology support related contract that requires minimum annual payments of $80 million in 2013 and declining to $70 million in 2014 through 2019.

Capacity Purchase Agreements with Third Party Regional Airlines

On September 11, 2012, American entered into capacity purchase agreements with SkyWest Airlines, Inc. (SkyWest) and with ExpressJet Airlines, Inc. (ExpressJet), both wholly owned subsidiaries of SkyWest, Inc., to provide 50-seat regional jet feed. Both airlines will operate the services under the American Eagle brand. SkyWest began service from Los Angeles International Airport on November 15, 2012, and ExpressJet is scheduled to begin service from Dallas-Ft. Worth International Airport on February 14, 2013. In addition, Chautauqua continued to operate under the brand AmericanConnection^® during 2012 under a capacity purchase agreement with American, which capacity purchase agreement was extended on November 1, 2012 to provide that Chautauqua will continue to operate in the American network into 2014.

As of December 31, 2012, American's capacity purchase agreements with third party regional airlines had expiration dates ranging from 2014 to 2017, with rights of American to extend the respective terms of each agreement. See Item 2, “Properties” for information on the aircraft contractually obligated to American under such capacity purchase agreements with third party regional airlines.

Under these agreements, the third party regional airlines operate certain of their aircraft using American's flight designator codes, and American controls the scheduling, pricing, reservations, ticketing and seat inventories of those aircraft and retains all revenues associated with revenue flights by those aircraft. American pays the third party regional airlines an amount, as defined in the applicable agreement, based on the airlines' costs of operating those flights and other factors intended to approximate market rates for those services.

As of December 31, 2012, American's minimum fixed obligations under its capacity purchase agreements with third party regional airlines were approximately $249 million in 2013, $188 million in 2014, $179 million in 2015, $170 million in 2016, $11 million in 2017 and $0 million in 2018 and beyond. These obligations contemplate minimum levels of flying by the third party airlines under the respective agreements and also reflect assumptions regarding certain costs associated with the minimum levels of flying such as the cost of fuel, insurance, catering, property tax and landing fees. Accordingly, actual payments under these agreements could differ materially from the minimum fixed obligations set forth above.

If American terminates the Chautauqua contract without cause, Chautauqua has the right to put its 15 Embraer aircraft to American. If this were to happen, American would take possession of the aircraft and become liable for lease obligations totaling approximately $20 million per year with lease expirations in 2018 and 2019.

See Note 17 for additional information on the Company's capacity purchase agreements.

Other

The Company 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. The Company is not able to estimate the potential amount of any liability resulting from the indemnities. These indemnities are discussed in the following paragraphs.

In its aircraft financing agreements, the Company generally indemnifies 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.

The Company’s loan agreements and other London Interbank Offered Rate (LIBOR)-based financing transactions (including certain leveraged aircraft leases) generally obligate the Company 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, the Company’s loan agreements, derivative contracts and other financing arrangements typically contain a withholding tax provision that requires the Company 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 the Company 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 and derivative transactions, 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, the Company may be required to make a lump sum payment to terminate the relevant transaction.

The Company has general indemnity clauses in many of its airport and other real estate leases where the Company as lessee indemnifies the lessor (and related parties) against liabilities related to the Company’s 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, the Company provides environmental indemnities in many of these leases for contamination related to the Company’s use of the leased property.

Under certain contracts with third parties, the Company indemnifies 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. The Company has liability insurance protecting the Company for some of the obligations it has undertaken under these indemnities.

AMR and American have event risk covenants in approximately $497 million of indebtedness and operating leases as of December 31, 2012. These covenants permit the holders of such obligations to receive a higher rate of return (between 100 and 600 basis points above the stated rate) if a designated event, as defined, should occur and the credit ratings of such obligations are downgraded below certain levels within a certain period of time. No designated event, as defined, had occurred as of December 31, 2012.

The Company is involved in certain claims and litigation related to its operations. The Company is also subject to regulatory assessments in the ordinary course of business. AMR establishes 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 the Company’s consolidated financial position, results of operations, or cash flows, after consideration of available insurance.

In the fourth quarter of 2012, the Company entered into a settlement agreement resolving a commercial dispute. The settlement agreement includes two elements which were valued at relative fair value and will be recognized when earned. The Company determined that the settlement includes a litigation gain of $280 million, which was valued using future cash flows and recognized in the fourth quarter of 2012. The settlement also includes an incentive which is contingent upon signing a future contract and will be recognized over the term of the future contract, when and if signed.

As a result of the filing of the Chapter 11 Cases, attempts to prosecute, collect, secure or enforce remedies with respect to prepetition claims against the Debtors are subject to the automatic stay provisions of section 362(a) of the Bankruptcy Code, except in such cases where the Bankruptcy Court has entered an order modifying or lifting the automatic stay. Notwithstanding the general application of the automatic stay described above, governmental authorities, both domestic and foreign, may determine to continue actions brought under their regulatory powers. Therefore, the automatic stay may have no effect on certain matters, and the Debtors cannot predict the impact, if any, that its Chapter 11 Cases might have on its commitments and obligations.

Leases [Abstract]

Leases

6. Leases

AMR’s subsidiaries lease various types of equipment and property, primarily aircraft and airport facilities. As allowed under section 365 and other relevant sections of the Bankruptcy Code, the Debtors may assume, assume and assign, or reject certain executory contracts and unexpired leases, including, without limitation, leases of real property, aircraft, and aircraft engines, subject to the approval of the Bankruptcy Court and other conditions, including compliance with section 1110 with respect to aircraft and aircraft-related assets. As of December 31, 2012, the Company had completed substantially all of its expected activities under section 365 of the Bankruptcy Code, including negotiating revised economic terms for its mainline aircraft in the Company's fleet. The Company's liabilities pertaining to leases may still change significantly in the future as differences between amounts scheduled by the Debtors and claims by creditors are investigated. See Note 1 to the consolidated financial statements for further information on the Company's Chapter 11 process, including the section 365 process and the magnitude of potential claims.

The future minimum lease payments required under capital leases, together with the present value of such payments, and future

minimum lease payments required under operating leases that have initial or remaining non-cancelable lease terms in excess of one year as of December 31, 2012, were (in millions):



	Capital Leases			Operating Leases
Year Ending December 31,
2013	$	82		$	1,031
2014	69			961
2015	63			891
2016	56			815
2017	52			776
2018 and thereafter	360			4,531
	$	682		$	9,005	⁽²⁾
Less amount representing interest	251
Present value of net minimum lease payments	$	431	⁽¹⁾

⁽¹⁾As of December 31, 2012, included in Liabilities Subject to Compromise on the accompanying consolidated balance sheet is approximately $19 million relating to ground capital leases.

⁽²⁾ As of December 31, 2012, $201 million and $160 million are included on the accompanying balance sheet in Liabilities Subject to Compromise and Accrued liabilities and other liabilities and deferred credits, respectively, relating to rent expense being recorded in advance of future operating lease payments.

American has entered into sale-leaseback arrangements with certain leasing companies to finance 26 Boeing 737-800 scheduled to be delivered from January 2013 through 2014 and one Boeing 777-300ER aircraft scheduled to be delivered in 2013 The financings of each aircraft under these arrangements are subject to certain terms and conditions. In addition, in some instances, they are also subject to collaboration with the Creditors' Committee and other key stakeholders and to the approval of the Bankruptcy Court.

During 2012, American financed 30 Boeing 737-800 and two 777-300ER aircraft under sale-leaseback arrangements, which are accounted for as operating leases. These sale-leaseback transactions resulted in gains which are being amortized over the respective remaining lease terms. During 2011, the Company incurred approximately $31 million in non-recurring non-cash charges related to certain sale-leaseback transactions. During 2010, the Company financed 36 deliveries of Boeing 737-800 aircraft through sale-leaseback transactions resulting in gains which are being amortized over the respective remaining lease terms.

At December 31, 2012, the Company was operating 215 jet aircraft and 9 turboprop aircraft under operating leases and 33 jet aircraft under capital leases. Leases can generally be renewed at rates based on fair market value at the end of the lease term for a number of additional years.

Special facility revenue bonds have been issued by certain municipalities primarily to improve airport facilities and purchase equipment. To the extent these transactions were committed to prior to May 21, 1998, they are accounted for as operating leases under U.S. GAAP. In accordance with various orders of the Bankruptcy Court, special facility revenue bond claims (totaling approximately $1.1 billion) in connection with the Alliance Airport, Dallas-Fort Worth International Airport and Luis Munoz Marin International Airport in San Juan are expected to be treated as general unsecured claims. Approximately $486 million of the special facility revenue bonds that had not been compromised as of December 31, 2012 (with total future payments of approximately $822 million as of December 31, 2012) are guaranteed by American, AMR, or both. Approximately $112 million of these special facility revenue bonds contain mandatory tender provisions that require American to make operating lease payments sufficient to repurchase the bonds in 2014. Although American has the right to remarket the bonds, there can be no assurance that these bonds will be successfully remarketed. Any payments to redeem or purchase bonds that are not remarketed would generally reduce existing rent leveling accruals or be considered prepaid facility rentals and would reduce future operating lease commitments. The special facility revenue bonds that contain mandatory tender provisions are listed in the table above at their ultimate maturity date rather than their mandatory tender provision date.

Rent expense, excluding landing fees, was $1.4 billion, $1.6 billion and $1.4 billion in 2012, 2011 and 2010, respectively.

American has determined that it holds a significant variable interest in, but is not the primary beneficiary of, certain trusts that are the lessors under 19 of its aircraft operating leases. These leases contain a fixed price purchase option, which allows American to

purchase the aircraft at a predetermined price on a specified date. However, American does not guarantee the residual value of the aircraft. As of December 31, 2012, future lease payments required under these leases totaled $98 million.

The financings listed in the table above are considered not subject to compromise. For information regarding the liabilities subject to compromise, see Note 1 and Note 8 to the consolidated financial statements.

The Company’s future long-term debt and operating lease payments have changed as its ordered aircraft are delivered and such deliveries have been financed. As of December 31, 2012, maturities of long-term debt (including sinking fund requirements) for the next five years are:



Years Ending December 31 (in millions)	Principal Not Subject to Compromise		Principal Subject to Compromise		Total Principal Amount
2013	$	1,388	$	93	$	1,481
2014	857		152		1,009
2015	758		6		764
2016	1,751		5		1,756
2017	492		42		534

Principal Not Subject to Compromise and Subject to Compromise includes payments not made due to the Chapter 11 Cases of $1 million and $50 million respectively.

As of December 31, 2012, AMR had issued guarantees covering approximately $1.5 billion of American’s tax-exempt bond debt (and interest thereon) and $4.2 billion of American’s secured debt (and interest thereon). American had issued guarantees covering approximately $842 million of AMR’s unsecured debt (and interest thereon). AMR also guarantees $6.3 million of American’s leases of certain Super ATR aircraft and certain Embraer RJ-135 aircraft, which are subleased to AMR Eagle.

During 2012, the Company entered into a series of agreements with the lender with respect to its 216 Embraer RJ aircraft and certain other interested parties pursuant to which the Company (i) surrendered 18 Embraer RJ 135 aircraft on June 21, 2012, (ii) subject to certain conditions (including reaching agreement on definitive documentation), will restructure the mortgage debt encumbering 59 Embraer 140 aircraft and 68 Embraer 145 aircraft and (iii) transferred and leased back its remaining 21 Embraer RJ 135 aircraft. The debt encumbering 50 Embraer 145 aircraft will not be reduced. The Company's entry into these transactions was approved by the Bankruptcy Court on November 8, 2012. The modifications to the financing arrangement for the Embraer RJ-140, RJ-145, and RJ-135 aircraft meet the definition of troubled debt restructurings per ASC 470-60 "Troubled Debt Restructurings by Debtors", and resulted in a gain of approximately $380 million, or $1.13 gain per share, offset by estimated claims filed by the creditor of approximately $592 million and a loss on the asset transfer of approximately $64 million. The estimated net loss of $276 million is included as a component of reorganization items, net.

On January 25, 2011, American closed on a $657 million offering of Class A and Class B Pass Through Trust Certificates, Series 2011-1 (the 2011-1 Certificates). Interest of 5.25% and 7.00% per annum on the issued and outstanding Series A equipment notes and Series B equipment notes, respectively, will be payable semiannually on January 31 and July 31 of each year, commencing

on July 31, 2011, and principal on such equipment notes is scheduled for payment on January 31 and July 31 of certain years, commencing on July 31, 2011. The payment obligations of American under the equipment notes are fully and unconditionally guaranteed by AMR. All proceeds from the sale of the Series 2011-1 Certificates have been received by American.

In March 2011, American issued $1.0 billion aggregate principal amount of senior secured notes due 2016 (the Senior Secured Notes) guaranteed by the Company. The Senior Secured Notes bear interest at a rate of 7.50% per annum, payable semi-annually on March 15 and September 15 of each year, beginning September 15, 2011. As is customary for financings of this nature, the indebtedness evidenced by the Senior Secured Notes may be accelerated upon the occurrence of events of default under the related indenture. The Senior Secured Notes are senior secured obligations of American and are unconditionally guaranteed on an unsecured basis by the Company. Subject to certain limitations and exceptions, the Senior Secured Notes are secured by certain route authorities, airport landing and takeoff slots, and rights to use or occupy space in airport terminals, in each case that American uses to operate non-stop services between certain airports in the United States and London’s Heathrow Airport, and between certain airports in the United States and certain airports in Japan and China.

American, at its option, may redeem some or all of the Senior Secured Notes at any time on or after March 15, 2013, at specified redemption prices, plus accrued and unpaid interest, if any. In addition, at any time prior to March 15, 2013, American, at its option, may redeem some or all of the Senior Secured Notes at a redemption price equal to 100% of their principal amount plus a “make-whole” premium and accrued and unpaid interest, if any. In addition, at any time prior to March 15, 2014, American, at its option, may redeem (1) up to 35% of the aggregate principal amount of the Senior Secured Notes with the proceeds of certain equity offerings at a redemption price of 107.5% of their principal amount, plus accrued and unpaid interest, if any, and (2) during any 12-month period, up to 10% of the original aggregate principal amount of the Senior Secured Notes at a redemption price of 103% of their principal amount, plus accrued and unpaid interest, if any. If American sells certain assets or if a “change of control” (as defined in the indenture) occurs, American must offer to repurchase the Senior Secured Notes at prices specified in the indenture.

The indenture for the Senior Secured Notes includes covenants that, among other things, limit the ability of the Company and its subsidiaries to merge, consolidate, sell assets, incur additional indebtedness, issue preferred stock, make investments and pay dividends.

On October 4, 2011, American closed on a $726 million offering of Class A Pass Through Trust Certificates, Series 2011-2 (the 2011-2 Certificates). Interest of 8.625% per annum on the issued and outstanding 2011-2 Certificates will be payable semiannually on April 15 and October 15 of each year, commencing on April 15, 2012, and principal on such equipment notes is scheduled for payment on April 15 and October 15 of certain years, commencing on April 15, 2012. The payment obligations of American under the equipment notes are fully and unconditionally guaranteed by AMR. All proceeds from the sale of the Series 2011-2 Certificates have been received by American.

In 2009, American entered into an arrangement under which Citibank paid to American $1 billion in order to pre-purchase AAdvantage Miles (the Advance Purchase Miles) under American’s AAdvantage frequent flier loyalty program (the Advance Purchase). Approximately $890 million of the Advance Purchase proceeds was accounted for as a loan from Citibank with the remaining $110 million recorded as Deferred Revenue in Other liabilities and deferred credits.

To effect the Advance Purchase, American and Citibank entered into an Amended and Restated AAdvantage Participation (as so amended and restated, the Amended Participation Agreement). Under the Amended Participation Agreement, American agreed that it would apply in equal monthly installments, over a five year period beginning on January 1, 2012, the Advance Purchase Miles to Citibank cardholders’ AAdvantage accounts.

Pursuant to the Advance Purchase, Citibank has been granted a first-priority lien on certain of American’s AAdvantage program assets, and a second lien on the collateral that secures the Senior Secured Notes. Commencing on December 31, 2011, American has the right to repurchase, without premium or penalty, any or all of the Advance Purchase Miles that have not then been posted to Citibank cardholders’ accounts. American is also obligated, in certain circumstances (including certain specified termination events under the Amended Participation Agreement, certain cross defaults and cross acceleration events, and if any Advance Purchase Miles remain at the end of the term) to repurchase for cash all of the Advance Purchase Miles that have not then been used by Citibank.

The Amended Participation Agreement includes provisions that grant Citibank the right to use Advance Purchase Miles on an accelerated basis under specified circumstances. American also has the right under certain circumstances to release, or substitute other comparable collateral for, the Heathrow and Narita route and slot related collateral.

Certain of the American’s debt financing agreements contain loan to value ratio covenants and require American to periodically appraise the collateral. Pursuant to such agreements, if the loan to value ratio exceeds a specified threshold, American is required, as applicable, to subject additional qualifying collateral (which in some cases may include cash collateral), or pay down such financing, in whole or in part, with premium (if any), or pay additional interest on the related indebtedness, as described below.

Specifically, American is required to meet certain collateral coverage tests on a periodic basis on two financing transactions: (1) 10.5% $450 million Senior Secured Notes due 2012, (the 10.5% Notes) and (2) Senior Secured Notes, as described below:



	(1) 10.5% Notes		(2) Senior Secured Notes
Frequency of Appraisals	Semi-Annual (April and October, ending April 2011)		Semi-Annual (June and December)
LTV Requirement	43%; failure to meet collateral test requires posting of additional collateral		1.5x Collateral valuation to amount of debt outstanding (67% LTV); failure to meet collateral test results in American paying 2% additional interest until the ratio is at least 1.5x; additional collateral can be posted to meet this requirement
LTV as of Last Measurement Date	47.5%		38.8%
			Generally, certain route authorities, take-off and landing slots, and rights to airport facilities used by American to operate certain services between the U.S. and London Heathrow, Tokyo Narita/Haneda, and China
Collateral Description	143 aircraft consisting of:
	Type	# of Aircraft

	MD-80	74
	B757-200	41
	B767-200ER	3
	B767-300ER	25
	TOTAL	143

At December 31, 2012, the Company was in compliance with the most recently completed collateral coverage tests for the Senior Secured Notes. As of December 31, 2012, American had $41 million of cash collateral posted with respect to the 10.5% Notes but was not in compliance with the most recently completed collateral coverage test for that transaction. The Company has not remedied its non-compliance with that test due to the ongoing Chapter 11 Cases. On October 1, 2012, the indebtedness underlying the 2005 Spare Engine EETC with respect to which American was required to comply with a collateral coverage test was paid in full, so American is no longer required to comply with a collateral coverage test for that transaction.

Cash payments for interest, net of capitalized interest, were $498 million, $628 million and $627 million for 2012, 2011 and 2010, respectively.

Almost all of the Company’s aircraft assets (including aircraft and aircraft-related assets eligible for the benefits of section 1110 of the Bankruptcy Code) are encumbered, and the Company has a very limited quantity of assets which could be used as collateral in financing.

The Chapter 11 Cases triggered defaults on substantially all debt and lease obligations of the Debtors. However, under section 362 of the Bankruptcy Code, the commencement of a Chapter 11 case automatically stays most creditor actions against the Debtors’ estates.

The Debtors cannot predict the impact, if any, that the Chapter 11 Cases might have on these obligations. For further information

regarding the Chapter 11 Cases, see Note 1 to the consolidated financial statements.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Financial Instruments and Risk Management

8. Financial Instruments and Risk Management

Fuel Price Risk Management As part of the Company’s risk management program, it uses a variety of financial instruments, primarily heating oil, jet fuel, and Brent crude option and collar contracts, as cash flow hedges to mitigate commodity price risk. The Company does not hold or issue derivative financial instruments for trading purposes. As of December 31, 2012, the Company had fuel derivative contracts outstanding covering 16 million barrels of jet fuel that will be settled over the next twelve months. A deterioration of the Company’s liquidity position and its Chapter 11 filing may negatively affect the Company’s ability to hedge fuel in the future.

In accordance with U.S. GAAP, the Company assesses, both at the inception of each hedge and on an ongoing basis, whether the derivatives that are used in its hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. Derivatives that meet the requirements are granted special hedge accounting treatment, and the Company’s hedges generally meet these requirements. Accordingly, the Company’s fuel derivative contracts are accounted for as cash flow hedges, and the fair value of the Company’s hedging contracts is recorded in Current Assets or Current Liabilities in the accompanying consolidated balance sheets until the underlying jet fuel is purchased. The Company determines the ineffective portion of its fuel hedge contracts by comparing the cumulative change in the total value of the fuel hedge contract, or group of fuel hedge contracts, to the cumulative change in a hypothetical jet fuel hedge. If the total cumulative change in value of the fuel hedge contract more than offsets the total cumulative change in a hypothetical jet fuel hedge, the difference is considered ineffective and is immediately recognized as a component of Aircraft fuel expense. Effective gains or losses on fuel hedging contracts are deferred in Accumulated other comprehensive income (loss) and are recognized in earnings as a component of Aircraft fuel expense when the underlying jet fuel being hedged is used.

Ineffectiveness is inherent in hedging jet fuel with derivative positions based in crude oil or other crude oil related commodities. In assessing effectiveness, the Company uses a regression model to determine the correlation of the change in prices of the commodities used to hedge jet fuel (e.g., NYMEX Heating oil) to the change in the price of jet fuel. The Company also monitors the actual dollar offset of the hedges’ market values as compared to hypothetical jet fuel hedges. The fuel hedge contracts are generally deemed to be “highly effective” if the R-squared is greater than 80 percent and dollar offset correlation is within 80 percent to 125 percent. The Company discontinues hedge accounting prospectively if it determines that a derivative is no longer expected to be highly effective as a hedge or if it decides to discontinue the hedging relationship. Subsequently, any changes in the fair value of these derivatives are marked to market through earnings in the period of change.

For the years ended December 31, 2012, 2011 and 2010, the Company recognized net gains/(losses) of approximately $4 million, $297 million and $(124) million, respectively, as a component of Aircraft fuel expense on the accompanying consolidated statements of operations related to its fuel hedging agreements, including the ineffective portion of the hedges. The net fair value of the Company’s fuel hedging agreements at December 31, 2012 and 2011, representing the amount the Company would receive upon termination of the agreements (net of settled contract assets), totaled $62 million and $80 million, respectively. As of December 31, 2012, the Company estimates that during the next twelve months it will reclassify from Accumulated other comprehensive income/(loss) into earnings approximately $15 million in net gains (based on prices as of December 31, 2012) related to its fuel derivative hedges.

The impact of cash flow hedges on the Company’s consolidated financial statements for the years ending December 31, 2012 and 2011, respectively, is depicted below (in millions):

¹ Effective portion of gain (loss)

² Ineffective portion of gain (loss)

The Company is also exposed to credit losses in the event of non-performance by counterparties to these financial instruments, and although no assurances can be given, the Company does not expect any of the counterparties to fail to meet its obligations. The credit exposure related to these financial instruments is represented by the fair value of contracts with a positive fair value at the reporting date, reduced by the effects of master netting agreements. To manage credit risks, the Company selects counterparties based on credit ratings, limits its exposure to a single counterparty under defined guidelines, and monitors the market position of the program and its relative market position with each counterparty. The Company also maintains industry-standard security agreements with a number of its counterparties which may require the Company or the counterparty to post collateral if the value of selected instruments exceed specified mark-to-market thresholds or upon certain changes in credit ratings.

As of December 31, 2012, the Company had posted cash collateral of approximately $0.6 million which is included in other assets.

Fair Values of Financial Instruments The fair values of the Company’s long-term debt classified as Level 2 were estimated using quoted market prices or discounted cash flow analyses, based on the Company’s current estimated incremental borrowing rates for similar types of borrowing arrangements. All of the Company’s long term debt not classified as subject to compromise is classified as Level 2.

The carrying value and estimated fair values of the Company’s long-term debt, including current maturities, not classified as subject to compromise, were (in millions):

Income Taxes

9. Income Taxes

The significant components of the income tax provision (benefit) were (in millions):

Deferred	(569		)	25			(30		)
Income tax benefit	$	(569	)	$	—		$	(35	)

The income tax expense (benefit) differed from amounts computed at the statutory federal income tax rate as follows (in millions):



	Year Ended December 31,
	2012			2011			2010
Statutory income tax provision expense/(benefit)	$	(873	)	$	(686	)	$	(177	)

Tax benefit resulting from OCI allocation	(569		)	—			—
Other, net	18			15			11
Income tax benefit	$	(569	)	$	—		$	(35	)

The Company recorded a $569 million non-cash income tax benefit from continuing operations during the fourth quarter of 2012. Under current accounting rules, the Company is required to consider all items (including items recorded in other comprehensive income) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. As a result, the Company recorded a tax benefit on the loss from continuing operations for the year, which will be exactly offset by income tax expense on other comprehensive income. However, while the income tax benefit from continuing operations is reported on the income statement, the income tax expense on other comprehensive income is recorded directly to Accumulated other comprehensive income, which is a component of stockholders’ equity. Because the income tax expense on other comprehensive income is equal to the income tax benefit from continuing operations, the Company’s year-end net deferred tax position is not impacted by this tax allocation.

The change in the valuation allowance reflects the recording by the Company in 2010 of an income tax expense credit of approximately $30 million resulting from the Company’s elections under applicable sections of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Housing and Economic Recovery Act of 2008 (as extended by the American Recovery and Reinvestment Act of 2009), allowing corporations to accelerate utilization of certain research and alternative minimum tax (AMT) credit carryforwards in lieu of applicable bonus depreciation on certain qualifying capital investments. These provisions were extended by passage of the American Taxpayer Relief Act of 2012, providing the potential for the Company to realize up to an additional $29 million in credits during 2013.

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 13 to the consolidated financial statements. The total increase in the valuation allowance was $282 million, $1.1 billion, and $120 million in 2012, 2011, and 2010, respectively.

The Company provides a valuation allowance for deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. In assessing the realizability of the deferred tax assets, management considers whether it is more likely than not that some portion, or all of the deferred tax assets, will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including reversals of deferred tax liabilities) during the periods in which those temporary differences will become deductible.

The components of the Company's deferred tax assets and liabilities were (in millions):



	December 31,
	2012			2011
Deferred tax assets:
Postretirement benefits other than pensions	$	442		$	1,075
Rent expense	60			257

Total deferred tax liabilities	(3,150		)	(3,222		)
Net deferred tax asset	$	—		$	—

At December 31, 2012, the Company had available for federal income tax purposes an AMT credit carryforward of approximately $493 million, which is available for an indefinite period, and federal net operating losses of approximately $6.8 billion for regular tax purposes, which will expire, if unused, beginning in 2022. These net operating losses include an unrealized benefit of approximately $666 million related to the implementation of share-based compensation accounting guidance that will be recorded in equity when realized. The Company had available for state income tax purposes net operating losses of $3.1 billion, which expire, if unused, in years 2013 through 2027. The amount that will expire in 2013 is $105 million if not used.

The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company’s 2004 through 2011 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination and the Company is under examination, in administrative appeals, or engaged in tax litigation in certain jurisdictions. The Company believes that the effect of any additional assessment(s) will be immaterial to its consolidated financial statements.

Cash payments (refunds) for income taxes were $5 million, $(0.5) million and $(32) million for 2012, 2011 and 2010, respectively.

Under special tax rules (the Section 382 Limitation), cumulative stock ownership changes among material shareholders exceeding 50 percent during a three year period can potentially limit a company’s future use of net operating losses and tax credits. Chapter 11 proceedings could impact the availability and utilization of net operating losses and tax credits. Based on available information, the Company believes it is not currently subject to the Section 382 Limitation.

Under special tax rules (the Section 382 Limitation), cumulative stock ownership changes among material shareholders exceeding 50 percent during a rolling three year period can potentially limit a company’s future use of net operating losses and tax credits. See discussion under Item 1A, "Risk Factors - Chapter 11 Reorganization Risks" regarding the potential impact of these rules on the company's utilization of its net operating losses.

The Company has an unrecognized tax benefit of approximately $5 million, which did not change during the twelve months ended December 31, 2012. Changes in the unrecognized tax benefit have no impact on the effective tax rate due to the existence of the valuation allowance. Accrued interest on tax positions is recorded as a component of interest expense but was not significant at December 31, 2012.

The reconciliation of the beginning and ending amounts of unrecognized tax benefit are (in millions):



	2012		2011
Unrecognized Tax Benefit at January 1	$	5	$	5
No Activity	—		—
Unrecognized Tax Benefit at December 31	$	5	$	5

The Company estimates that the unrecognized tax benefit will not significantly change within the next twelve months.

10. Share Based Compensation

Prior to the Petition Date, AMR adopted certain plans which provide for the issuance of common stock in connection with the exercise of stock options and for other stock-based awards. AMR has granted stock compensation under three plans: the 1998 Long Term Incentive Plan (the 1998 Plan), the 2003 Employee Stock Incentive Plan (the 2003 Plan) and the 2009 Long Term Incentive Plan (the 2009 Plan). Collectively, the 1998 Plan and the 2009 Plan are referred to as the LTIP Plans.

The Company believes that all of its stock options could be cancelled as part of the emergence of AMR and its subsidiaries, including the Company, from Chapter 11. The following includes additional information about these plans as of December 31, 2012. No awards were made under these plans in 2012, and it is expected that no future awards will be made under these existing plans.

Under the LTIP Plans, officers and key people of AMR and its subsidiaries, including the Company, were granted certain types of stock or performance based awards. At December 31, 2012, AMR had AMR stock option awards, stock appreciation right (SAR) awards, performance share awards, deferred share awards and other awards outstanding under these plans. The total number of common shares authorized for distribution under the 1998 Plan and the 2009 Plan is 23,700,000 and 4,000,000 shares, respectively. The 1998 Plan expired by its terms in 2008.

AMR established the 2003 Plan to provide equity awards to employees. Under the 2003 Plan, employees may be granted stock options, restricted stock and deferred stock. At December 31, 2012, the AMR had stock options and deferred awards outstanding under this plan. The total number of shares authorized for distribution under the 2003 Plan is 42,680,000 shares.

In 2012, 2011 and 2010, the total charge for share-based compensation expense included in Wages, salaries and benefits expense was $26 million, $40 million and $49 million, respectively. In 2012, 2011 and 2010, the amount of cash used to settle equity instruments granted under share-based compensation plans was $0 million, $2 million and $2 million, respectively.

Stock Options/SARs During 2006, the AMR Board of Directors approved an amendment covering all of the outstanding stock options previously granted under the 1998 Plan. The amendment added to each of the outstanding options an additional SAR in tandem with each of the then outstanding stock options. The addition of the SAR did not impact the fair value of the stock options, but simply allowed the Company to settle the exercise of the option by issuing the net number of shares equal to the in-the-money value of the option. This amendment is estimated to make available enough shares to permit the Company to settle all outstanding performance and deferred share awards under the 1998 Plan in stock rather than cash.

Options/SARs granted under the LTIP Plans and the 2003 Plan are awarded with an exercise price equal to the fair market value of AMR stock on date of grant, become exercisable in equal annual installments over periods ranging from three to five years and expire no later than ten years from the date of grant. Expense for the options is recognized on a straight-line basis. The fair value of each award is estimated on the date of grant using the modified Black-Scholes option valuation model and the assumptions noted in the following table. Expected volatilities are based on implied volatilities from traded options on AMR's stock, historical volatility of AMR's stock, and other factors. The Company uses historical employee exercise data to estimate the expected term of awards granted used in the valuation model. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is assumed to be zero based on AMR's history and expectation of not paying dividends.



	2012¹		2011		2010
Expected volatility	—		73.5% to 75.4%		74.4% to 75.9%
Expected term (in years)	—		4.0		4.0
Risk-free rate	—		0.90% to 2.11%		1.18% to 2.58%
Annual forfeiture rate	—	%	10.0	%	10.0	%

¹ No options/SARs were granted in 2012.

A summary of stock option/SARs activity under the LTIP Plans and the 2003 Plan as of December 31, 2012, and changes during

the year then ended is presented below:



	LTIP Plans					The 2003 Plan
	Options/SARs			Weighted Average Exercise Price		Options			Weighted Average Exercise Price
Outstanding at January 1	13,809,841			$	10.31	13,082,905			$	5.66

Weighted Average Remaining Contractual Term of Options Outstanding (in years)	6.3					0.4
Aggregate Intrinsic Value of Options Outstanding	$	—				$	—

There is no intrinsic value of vested options/SARs at December 31, 2012. The weighted-average grant date fair value of options/SARs granted during 2011 and 2010 was $3.59 and $3.97, respectively. The total intrinsic value of options/SARs exercised 2011 and 2010 was less than $1 million and $1 million, respectively.

A summary of the status of the Company’s non-vested options/SARs under all plans as of December 31, 2012, and changes during the year ended December 31, 2012, is presented below:



	Options/SARs		Weighted Average Grant Date Fair Value
Outstanding at January 1	7,468,019		$	3.59
Granted	—		—
Vested	(2,022,036	)	3.89
Forfeited	(787,577	)	3.54
Outstanding at December 31	4,658,406		$	3.47

As of December 31, 2012, there was $6 million of total unrecognized compensation cost related to non-vested stock options/SARs granted under the LTIP Plans and the 2003 Plan that is expected to be recognized over a weighted-average period of 2.5 years. The total fair value of stock options/SARs vested during the years ended December 31, 2012, 2011 and 2010, was $5 million, $7 million and $11 million, respectively.

The Company received no cash from exercise of stock options for the year ended December 31, 2012 and received $1 million for the years ended December 31, 2011 and 2010. No tax benefit was realized as a result of stock options/SARs exercised in 2012 due to the tax valuation allowance discussed in Note 9.

Performance Share Awards Performance share awards are granted under the LTIP Plans, generally vest pursuant to a three year measurement period and are settled on the vesting date. The number of awards ultimately issued under performance share awards is contingent on AMR’s relative stock price performance compared to certain of its competitors over a three year period and can range from zero to 175 percent of the awards granted. The fair value of performance awards is calculated by multiplying the stock price on the date of grant by the expected payout percentage and the number of shares granted.

Activity during 2012 for performance awards accounted for as equity awards was:



	Awards		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value
Outstanding at January 1	6,341,695
Granted	—
Settled	—
Forfeited or Expired	(197,695	)
Outstanding at December 31	6,144,000		0.2	$	4,915,200

The aggregate intrinsic value represents the Company’s current estimate of the number of shares (6,144,000 shares at December 31, 2012) that will ultimately be distributed for outstanding awards computed using the market value AMR's common stock at December 31, 2012. The weighted-average grant date fair value per share of performance share awards granted during 2011 and 2010 was $6.58 and $7.01, respectively. As of December 31, 2012, there was $2 million of total unrecognized compensation cost related to performance share awards that is expected to be recognized during 2013.

Deferred Share Awards The distribution of deferred share awards granted under the LTIP Plans is based solely on a requisite service period (generally 36 months). Career equity awards granted to certain employees of the Company vest upon the retirement of those individuals. The fair value of each deferred award is based on AMR’s stock price on the measurement date.

Activity during 2012 for deferred awards accounted for as equity awards was:



	Shares		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value
Outstanding at January 1	7,271,021
Granted	—
Settled	(24,840	)
Forfeited or Expired	(481,124	)
Outstanding at December 31	6,765,057		0.9	$	5,412,045

The weighted-average grant date fair value per share of deferred awards granted during 2011 and 2010 was $6.29 and $7.05, respectively. The total fair value of awards settled during the years ended December 31, 2011 and 2010 was $1 million and $3 million, respectively. As of December 31, 2012, there was $6 million of total unrecognized compensation cost related to deferred awards that is expected to be recognized over a weighted average period of 2.3 years.

Other Awards As of December 31, 2012, certain performance share agreements and deferred share award agreements were accounted for as a liability, or as equity, as appropriate, in the consolidated balance sheet as the plans only permit settlement in cash or the awards required that the employee meet certain performance conditions which were not subject to market measurement. As a result, awards under these agreements are marked to current market value. As of December 31, 2012, the aggregate intrinsic value of these awards was $2 million and the weighted average remaining contractual term of these awards was 1.3 years. The total fair value of awards settled during the years ended December 31, 2012, 2011 and 2010 was $0 million, $2 million, and $2 million respectively. As of December 31, 2012, there was $1 million of total unrecognized compensation cost related to other awards that is expected to be recognized over a weighted average period of 1.3 years.

The Company does not intend to assume any equity-based awards that were outstanding at the commencement date of its Chapter 11 Case.

Compensation And Retirement Disclosure [Abstract]

Retirement Benefits

11. Retirement Benefits

The Company sponsors defined benefit and defined contribution pension plans for eligible employees. The defined benefit plans provide benefits for participating employees based on years of service and average compensation for a specified period of time before retirement. The Company uses a December 31 measurement date for all of its defined benefit plans.

Modifications to Retirement and Life Insurance Benefits

On March 7, 2012, the Company announced that, in working with Creditors' Committee and the Pension Benefit Guarantee

Corporation (PBGC), it developed a solution that would allow the Company to pursue a freeze of its defined benefit pension plans for non-pilot employees instead of seeking termination. On September 14, 2012, the Company sent formal legal notice to all defined benefit plan participants and beneficiaries announcing that it was freezing each of the defined benefit pension plans. The freeze of these plans became effective as scheduled on November 1, 2012. Eligible non-pilot employees began to receive a replacement benefit under the $uper $aver 401(k) Plan on November 1, 2012, with the Company matching employee contributions up to 5.5 percent of eligible earnings. With the ratification of a new collective bargaining agreement by pilots on December 7, 2012, pilots began to receive a replacement benefit in the form of a Company contribution to the $uper $aver 401(k) Plan of 14 percent of eligible earnings for work performed beginning on November 1, 2012.

Effective November 8, 2012, the U.S. Treasury Department and the Internal Revenue Service published a Final Regulation establishing the process by which the Company could seek to amend certain structural aspects of the Pilot A Plan, a defined benefit plan. Under that process, the Company applied to the PBGC for a determination that it met the standard to amend the Plan to remove the lump-sum benefit feature and other similar optional forms of benefit. On December 13, 2012, the PBGC issued its determination that the Company has met the standard for amendment set forth in the Final Regulation. On November 23, 2012, the Company filed a motion in the Bankruptcy Court seeking approval of the A Plan amendment. After a hearing on December 19, 2012, the Court granted the motion. On December 21, 2012, the Company amended the A Plan to remove the lump-sum and other similar optional forms of benefit for commencements after December 31, 2012. A small group of American pilots is appealing the Bankruptcy Court's decision authorizing American to eliminate the lump sum and other similar optional forms of benefit. This is the same group of pilots that is appealing the Bankruptcy Court's decisions authorizing American to reject the pilot CBA and approving the new pilot CBA. All of these appeals have been consolidated, and are pending in the U.S. District Court for the Southern District of New York.

The Company also terminated the Pilot B Plan, a defined contribution plan, on November 30, 2012. Plan B assets will be distributed to pilots in mid-2013.

On September 14, 2012, the Company notified active employees of its plans to modify its subsidized retiree medical coverage on November 1, 2012. Those who initiate retiree medical coverage on or after November 1, 2012 will go into a new retiree medical program. For those who retire before age 65, two medical options will be available, but the Company will not be subsidizing them. Those who retire at age 65 and over may purchase a guaranteed-issue Medicare supplement plan. Flight attendants and TWU-represented employees will receive a refund of their prefunding retiree medical contributions within 120 days of November 1, 2012.

On March 23, 2012, the Bankruptcy Court entered a Stipulation and Order providing for the appointment of a committee of retired independent and unionized AMR employees (the "Retiree Committee"), and on May 3, 2012 appointed five members to the Retiree Committee. On August 15, 2012, the Company filed a proceeding in the Bankruptcy Court seeking a determination on the issue of vesting for former employees who retired and initiated retiree medical coverage before November 1, 2012. The Court held a hearing on January 23, 2013 and has not ruled on this matter as of the date of this report. On September 20, 2012, the Company opened negotiations with the Retiree Committee, seeking a consensual agreement to terminate subsidized retiree medical coverage and life insurance coverage. Those negotiations are continuing.

As a result of the modifications to the retirement benefits as discussed above, a portion of the pension and postretirement benefits liability, primarily relating to retiree medical and other benefits, was classified as liabilities subject to compromise as of December 31, 2012.

Curtailment and Plan Amendment in the Third Quarter of 2012

In accordance with ASC 715 “Retirement Benefits” (ASC 715), in the third quarter of 2012 the Company remeasured its defined benefit pension and retiree medical plans as a result of modifications to its retirement plans and reductions in certain work groups (see above and Note 1 to the consolidated financial statements). The Company updated its significant actuarial assumptions used for the remeasurements including the discount rate, which was lowered to 4.10 percent and 3.80 percent for the defined benefit pension plans and retiree medical plans, respectively.

The remeasurement of the defined benefit plans resulted in an actuarial loss of $1.9 billion offset by a curtailment gain of $1.8 billion. In addition, a loss of $58 million, representing unamortized prior service cost as of the remeasurement date of the frozen defined benefit plans, is included as a component of reorganization items, net.

Further, as a result of modifications to its retiree medical plans, the Company recognized a negative plan amendment of $1.9 billion, which is included as a component of actuarial gain arising in current year in other comprehensive income and will be amortized over the future service life of the active plan participants for whom the benefit was eliminated, or approximately 8 years.

In addition, a net credit of $124 million, representing unamortized prior service credits of $157 million offset by a curtailment loss of $33 million, is included as a component of reorganization items, net.

Expected return on plan assets	8.25		8.50		8.25		8.50

As of December 31, 2012, the Company’s estimate of the long-term rate of return on plan assets was 8.00 percent based on the target asset allocation. Expected returns on longer duration bonds are based on yields to maturity of the bonds held at year-end. Expected returns on other assets are based on a combination of long-term historical returns, actual returns on plan assets achieved over the last ten years, current and expected market conditions, and expected value to be generated through active management, currency overlay and securities lending programs. The Company’s annualized ten-year rate of return on plan assets as of December 31, 2012, was approximately 10.15 percent.

The objectives of the Company’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	60	%	-	70%
Public:
U.S. Value	18	%	-	33%
International Value	14	%	-	24%
Emerging Markets	5	%	-	11%
Alternative Investments	0	%	-	18%
Fixed Income	30	%	-	40%
U.S. Long Duration	30	%	-	40%

Other	0	%	-	5%
Cash Equivalents	0	%	-	5%

Each asset class is actively managed and, historically, the plans’ assets have produced returns, net of management fees, in excess of the expected rate of return over the last ten years. Stocks and emerging market bonds are used to provide diversification and are expected to generate higher returns over the long-term than longer duration U.S. 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. Longer duration U.S. 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 Company engages currency overlay managers in an attempt to increase returns by protecting non-U.S. dollar denominated assets from a rise in the relative value of the U.S. dollar. The Company also participates in securities lending programs to generate additional income by loaning plan assets to borrowers on a fully collateralized basis. These programs are subject to market risk.

Investments in securities traded on recognized securities exchanges are valued at the last reported sales price on the last business day of the year. Securities traded in the over-the-counter market are valued at the last bid price. The money market fund is valued at fair value which represents the net asset value of the shares of such fund as of the close of business at the end of the period. Investments in limited partnerships are carried at estimated net asset value as determined by and reported by the general partners of the partnerships and represent the proportionate share of the estimated fair value of the underlying assets of the limited partnerships. Common/collective trusts are valued at net asset value based on the fair values of the underlying investments of the

trusts as determined by the sponsor of the trusts. The 103-12 investment trust is valued at net asset value which is determined by the issuer at the end of each month and is based on the aggregate fair value of trust assets less liabilities, divided by the number of units outstanding. No changes in valuation techniques or inputs occurred during the period.

The fair values of the Company’s pension plan assets at December 31, 2012 and 2011, by asset category are as follows:

The Company is required to make minimum contributions to its defined benefit pension plans under the minimum funding requirements of ERISA, the Pension Funding Equity Act of 2004, the Pension Protection Act of 2006, and the Pension Relief Act of 2010.

As a result of the Chapter 11 Cases, AMR contributed $272 million to its US defined benefit pension plans in 2012 to cover post-petition periods. As a result of only contributing the post-petition portion of the required contribution, the PBGC filed a lien against certain assets of the Company. The Company’s 2013 contribution to its defined benefit pension plans is subject to the Chapter 11 proceedings.

The following benefit payments, which reflect expected future service as appropriate, are expected to be paid:



	Pension	Retiree Medical and Other
2013	$620	$135

Goodwill And Intangible Assets Disclosure [Abstract]

Intangible Assets

12. Intangible Assets

The Company has recorded international slot and route authorities of $708 million as of December 31, 2012 and 2011. The Company considers these assets indefinite life assets and as a result, they are not amortized but instead are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. Such triggering events may include significant changes to the Company’s network or capacity, or the implementation of open skies agreements in countries where the Company operates flights.

As there is minimal market activity for the valuation of routes and international slots and landing rights, the Company measures fair value with inputs using the income approach. The income approach uses valuation techniques, such as future cash flows, to convert future amounts to a single present discounted amount. The inputs utilized for these valuations are unobservable and reflect the Company’s assumptions about market participants and what they would use to value the routes and accordingly are considered Level 3 in the fair value hierarchy. The Company’s unobservable inputs are developed based on the best information available as of December 31, 2012.

The following tables provide information relating to the Company’s amortized intangible assets as of December 31 (in millions):



	2012
	Cost		Accumulated Amortization		Net Book Value
Amortized intangible assets:
Airport operating rights	$	515	$	385	$	130
Gate lease rights	155		124		31
Total	$	670	$	509	$	161



	2011
	Cost		Accumulated Amortization		Net Book Value
Amortized intangible assets:
Airport operating rights	$	509	$	361	$	148
Gate lease rights	160		125		35
Total	$	669	$	486	$	183

Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value. The Company recorded amortization expense related to these intangible assets of approximately $25 million, $27 million, and $28 million for the years ended December 31, 2012, 2011 and 2010, respectively. The Company expects to record annual amortization expense averaging approximately $19 million in each of the next five years related to these intangible assets.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	14. Transactions with Related Parties American invests funds, including funds of certain affiliates, if any, in a combined short-term investment portfolio and passes through interest income on such funds at the average rate earned on the portfolio. These amounts are classified as Payable to affiliate on the accompanying consolidated balance sheets. Pursuant to a capacity purchase agreement between American and the American Eagle carriers, American receives all passenger revenue from flights performed for it by the American Eagle carriers and pays the American Eagle carriers a fee for each flight. The capacity purchase agreement reflects what the Company believes are current market rates received by other regional carriers for similar flying. Amounts paid to the American Eagle carriers under the capacity purchase agreement are available to pay for various operating expenses of the American Eagle carriers, such as crew expenses, maintenance, and other aircraft related expenses. As of December 31, 2012, the American Eagle carriers operated approximately 1,500 daily departures, offering scheduled passenger service to over 175 destinations in North America, Mexico and the Caribbean. On a separate company basis, AMR Eagle reported $1.2 billion in revenue in 2012. However, this historical financial information is not indicative of what AMR Eagle’s future revenues might be if AMR Eagle were a stand-alone entity. In 2012 and 2011, American made payments to the American Eagle carriers of approximately $1.1 billion and $2.4 billion, respectively, related to the capacity purchase agreement. In addition, American incurred costs associated with generating Regional Affiliates revenue for flights on AMR Eagle of $128 million and $132 million in 2012 and 2011, respectively, recorded in Commissions, booking fees and credit card expense in the accompanying consolidated statements of operations. American also incurred other costs in connection with its affiliate relationship with AMR Eagle totaling approximately $1.6 billion and $350 million in 2012 and 2011, respectively, primarily recorded in Other operating expenses in the accompanying consolidated statements of operations. In consideration for certain services provided, the AMR Eagle carriers paid American approximately $16 million in 2012, $18 million in 2011 and $18 million in 2010. American recognizes compensation expense associated with certain AMR common stock-based awards for employees of American (see Note 10). In addition, American incurs pension and postretirement benefit expense for American employees working at affiliates of the Company. American transfers pension and postretirement benefit expense for these employees to its affiliates based on a percentage of salaries and cost per employee, respectively (see Note 11).

Segment Reporting [Abstract]

Segment Reporting

15. Segment Reporting

The Company’s operations of American and AMR Eagle are treated as an integrated route network and the route scheduling system maximizes the operating results of the Company. The Company’s chief operating decision maker makes resource allocation decisions to maximize the Company’s consolidated financial results. Based on the way the Company treats the network and the manner in which resource allocation decisions are made, the Company has only one operating segment for financial reporting purposes consisting of the operations of American and AMR Eagle.

American, together with the American Eagle carriers and the third party carriers that provide regional feed to American, serves more than 250 cities in approximately 50 countries with, on average, 3,400 daily flights. The combined network fleet numbers approximately 900 aircraft. American is also one of the largest scheduled air freight carriers in the world, providing a wide range of freight and mail services to shippers throughout its system onboard American’s passenger fleet.

Revenues from other segments are below the quantitative threshold for determining reportable segments and consist primarily of revenues from Americas Ground Services, Inc. The difference between the financial information of the Company’s one reportable segment and the financial information included in the accompanying consolidated statements of operations and balance sheets as a result of these entities is not material.

The Company’s operating revenues by geographic region (as defined by DOT) are summarized below (in millions):



	Year Ended December 31,
	2012		2011		2010
DOT Domestic	$	14,257	$	13,782	$	13,062
DOT Latin America	5,813		5,460		4,619
DOT Atlantic	3,411		3,499		3,365
DOT Pacific	1,344		1,216		1,104
Total consolidated revenues	$	24,825	$	23,957	$	22,150

The Company attributes operating revenues by geographic region based upon the origin and destination of each flight segment. The Company’s tangible assets consist primarily of flight equipment, which are mobile across geographic markets and, therefore, have not been allocated.

- Definition

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

17. Subsequent Events

Restructuring of Agreements with The Boeing Company and Amendment of Agreement with Airbus S.A.S.

American entered into an agreement on January 11, 2013 (the Restructuring Agreement) with Boeing that provides for the assumption and restructuring of certain existing aircraft purchase agreements (the Restructured Aircraft Purchase Agreements) between Boeing and American, the entering into of a definitive purchase agreement (the MAX purchase agreement) with respect to Boeing 737 MAX aircraft (the MAX aircraft), certain financing commitments for the Boeing 787 aircraft (the 787 aircraft) and certain Boeing 737-8 aircraft (the 737 aircraft), the assumption of certain other aircraft spare parts, support and services agreements, and a comprehensive settlement of the relationship among American and its affiliates and Boeing and certain affiliates of Boeing, including all claims asserted by Boeing and such affiliates in the Chapter 11 Cases, with certain limited exceptions.

The Bankruptcy Court issued an order on January 23, 2013 approving the Restructuring Agreement, assumption of the Restructured Aircraft Purchase Agreements, and the MAX purchase agreement.

The Restructured Aircraft Purchase Agreements provide for the substitution of up to 20 787-8 aircraft for 787-9 aircraft, an accelerated delivery schedule for the 787 aircraft with deliveries scheduled to commence in November 2014 and continue in each calendar year through September 2018, and the confirmation of the purchase of the Boeing 787 aircraft, which previously had been subject to certain reconfirmation rights. Under the Restructured Aircraft Purchase Agreements, American will have the option to purchase 40 737 aircraft, 13 777 aircraft and 58 787 aircraft.

Pursuant to the Restructuring Agreement, American entered into the MAX purchase agreement pursuant to which American will acquire 100 MAX aircraft, equipped with new, more fuel efficient engines. The MAX purchase agreement constitutes the definitive purchase agreement contemplated by and supersedes the agreement entered into by American and Boeing on July 19, 2011 (the 2011 MAX order) that provided for the commitment of American to purchase such MAX aircraft (referred to in the 2011 MAX order as 737RE aircraft). The 2011 MAX order was subject to a number of contingencies, including the parties entering into a definitive purchase agreement and Boeing's approval of the launch of the Boeing 737 re-engined aircraft program, which was approved in August, 2011. Under the MAX purchase agreement, the MAX aircraft are scheduled to be delivered in each of the years 2018 through 2022. In addition, under the MAX purchase agreement, American will have the option to purchase 60 additional MAX aircraft in the years 2020-2025.

American also, on January 11, 2013, entered into an amendment to the A320 Family Aircraft Purchase Agreement with Airbus, dated July 20, 2011 (the Airbus Amendment) specifying the scheduled delivery months of certain aircraft and revising the date by which American must notify Airbus of the engine selection of certain aircraft types. The Airbus Amendment became effective on January 23, 2013, when the Court entered an order approving assumption of the A320 Family Purchase Agreement. Agreements pursuant to which Airbus agreed to providing financing for the purchase of certain aircraft also were assumed.

Reflecting the above transactions, American had total aircraft acquisition commitments as follows:



		Boeing				Airbus
		737 Family	737 MAX	777-300 ER	787 Family	A320 Family	A320 NEO	Total
2013	Purchase	31	—	8	—	—	—	39
	Lease	—	—	—	—	20	—	20
2014	Purchase	5	—	6	2	—	—	13
2014	Lease	15	—	—	—	35	—	50
2015	Purchase	—	—	2	11	—	—	13
2015	Lease	20	—	—	—	30	—	50
2016	Purchase	—	—	2	13	—	—	15
2016	Lease	20	—	—	—	25	—	45
2017	Purchase	—	—	—	9	—	10	19
2017	Lease	20	—	—	—	20	—	40
2018 and beyond	Purchase	—	100	—	7	—	120	227
2018 and beyond	Lease	—	—	—	—	—	—	—
Total	Purchase	36	100	18	42	—	130	326
Total	Lease	75	—	—	—	130	—	205

Subject to assumption of certain of the related agreements, payments for the above purchase commitments and certain engines will approximate $2.3 billion in 2013, $1.5 billion in 2014, $1.7 billion in 2015, $2.1 billion in 2016, $2.1 billion in 2017 and $12.8 billion for 2018 and beyond. These amounts are net of purchase deposits currently held by the manufacturers. American has granted Boeing a security interest in American's purchase deposits with Boeing.

New Capacity Purchase Agreement

On January 23, 2013, American entered into a 12 year capacity purchase agreement with Republic Airline Inc. (Republic), a subsidiary of Republic Airways Holdings, to provide large regional jet flying. Through the agreement, which is subject to approval by the Bankruptcy Court, Republic will acquire 53 Embraer E-175 aircraft featuring a two-class cabin with 12 first class seats and 64 seats in the main cabin. The aircraft, which will fly under the American Eagle brand, will phase into operation at approximately two to three aircraft per month beginning in mid-2013. All 53 aircraft are expected to be in operation by the first quarter of 2015.

Reflecting the above transaction, American's minimum fixed obligations under its capacity purchase agreements with third party regional airlines will approximate $353 million in 2013, $589 million in 2014, $739 million in 2015, $736 million in 2016, $580 million in 2017 and $4.8 billion in 2018 and beyond. These obligations contemplate minimum levels of flying by the third party airlines under the respective agreements and also reflect assumptions regarding certain costs associated with the minimum levels of flying such as the cost of fuel, insurance, catering, property tax and landing fees. Accordingly, actual payments under these agreements could differ materially from the minimum fixed obligations set forth above.

EETC Transactions

The Company filed a motion with the Bankruptcy Court on October 9, 2012, requesting entry of an order authorizing American to, among other things: (i) obtain postpetition financing in an amount of up to $1.5 billion secured on a first priority basis by, among other things, up to 41 Boeing 737-823 aircraft, 14 Boeing 757-223 aircraft, one Boeing 767-323ER aircraft and 19 Boeing 777-223ER aircraft as part of a new enhanced equipment trust certificate (EETC) financing (the Refinancing EETC) to be offered pursuant to Rule 144A under the Securities Act of 1933 as amended, and (ii) use cash on hand (including proceeds of the Refinancing EETC) to indefeasibly repay the existing prepetition obligations secured by such aircraft, as applicable, which are currently financed through, as the case may be, an EETC financing entered into by American in July 2009 (the Series 2009-1 Pass Through Certificates), a secured notes financing entered into by American in July 2009 (the 2009-2 Senior Secured Notes) and an EETC financing entered into by American in October 2011 (the Series 2011-2 Pass Through Certificates and, together with the Series 2009-1 Pass Through Certificates and the 2009-2 Senior Secured Notes, the Existing Financings), in each case without the payment of any make-whole amount or other premium or prepayment penalty. American expects the Refinancing EETC structure to be substantially similar to the structure of the Series 2011-2 Pass Through Certificates, other than the economic terms (such as the interest rate) and certain terms and conditions to be in effect during its current Chapter 11 bankruptcy case.

The Bankruptcy Court approved the motion on January 17, 2013 and entered an order pursuant to such effect on February 1, 2013. The trustees for the Existing Financings have filed notice of appeal of such order of the Bankruptcy Court. The Company intends to continue to assert vigorously its rights to repay the Existing Financings without the payment of any make-whole amount or other premium or prepayment penalty, and the Company is considering all of its options, including the payment of the Existing Financings and closing the Refinancing EETC notwithstanding such appeal.

The Company filed a motion with the Bankruptcy Court on January 24, 2013, requesting entry of an order authorizing American to, among other things, (i) obtain postpetition financing in an amount of up to $750 million secured on a first priority basis by, among other things, up to eight Boeing 737-823 aircraft, one Boeing 777-223ER aircraft, and four Boeing 777-300ER aircraft as part of a new EETC financing (the New EETC) to be offered pursuant to Rule 144A under the Securities Act of 1933 as amended, and (ii) use cash on hand (including proceeds of the New EETC) to indefeasibly repay the existing prepetition obligations secured by certain of the Boeing 737-823 and Boeing 777-223ER aircraft, as applicable, which are currently financed through, as the case may be, prepetition mortgage loan facilities that are scheduled to mature in May 2013 and July 2013. American expects the New EETC structure to be substantially similar to other American EETCs, other than the economic terms (such as the interest rate) and certain terms and conditions to be in effect during its current Chapter 11 bankruptcy case.

The Bankruptcy Court entered an order approving the motion on February 15, 2013. There can be no assurance that either the Refinancing EETC or the New EETC will be able to be effected on acceptable terms, or at all.

Merger Agreement

Description of Agreement and Plan of Merger

On February 13, 2013, AMR Corporation (AMR), US Airways Group, Inc., a Delaware corporation (US Airways), and AMR Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of AMR (Merger Sub), entered into an Agreement and Plan of Merger (the Merger Agreement), providing for a business combination of AMR and US Airways. The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into US Airways (the Merger), with US Airways as the surviving corporation and as a wholly owned subsidiary of AMR, Following the Merger, AMR will own, directly or indirectly, all of the equity interests of American Airlines, Inc. (American), US Airways and their direct and indirect subsidiaries (herein, the New American) The Merger Agreement and the transactions contemplated thereby, including the Merger, are subject to the approval of the Bankruptcy Court (as defined below), and are to be effected pursuant to a plan of reorganization (the Plan) of the Company and certain of its direct and indirect domestic subsidiaries (the Debtors) in connection with their currently pending cases under chapter 11 of title 11 of the United States Code, 11 U.S.C. Sections 101 et seq. (the Bankruptcy Code) in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). The Plan is subject to confirmation and consummation in accordance with the requirements of the Bankruptcy Code.

Subject to the terms and conditions of the Merger Agreement, which has been approved by the boards of directors of the respective parties, if the Merger is completed, US Airways stockholders will receive one share of common stock of New American (New American Common Stock) for each share of US Airways common stock. The aggregate number of shares of New American Common Stock issuable to holders of US Airways equity instruments (including stockholders, holders of convertible notes, optionees and holders of restricted stock units) will represent 28% of the diluted capitalization of AMR after giving effect to the Plan. The remaining 72% diluted equity ownership of AMR will be distributable, pursuant to the Plan, to the Debtors' stakeholders, labor unions and certain employees.

All of the equity interests in New American will be issued solely pursuant to the Merger Agreement or the Plan. All existing AMR common stock and other equity interests in AMR will be cancelled pursuant to the Plan, although, as set forth below, holders of such equity interests are expected to receive a recovery in the form of New American Common Stock.

The Merger is intended to qualify, for federal income tax purposes, as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended.

The Merger Agreement provides that, upon consummation of the Merger, the board of directors of the combined company will initially consist of 12 members, composed of (i) Thomas W. Horton, AMR's current chairman, chief executive officer and president, who will serve as chairman of New American until the earlier of (A) one year after the closing of the Merger and (B) the day immediately prior to the first annual meeting of stockholders of the combined company (provided that such meeting will not occur prior to May 1, 2014), (ii) W. Douglas Parker, US Airways' current chief executive officer, who will serve as chief executive officer of New American and will serve as chairman of New American following the end of Mr. Horton's term, (iii) two independent directors designated by AMR, (iv) three independent directors designated by US Airways, and (iv) five independent directors designated by a search committee consisting of representatives of the Official Committee of Unsecured Creditors of the Debtors and certain representatives of creditors signatory to the support agreements with AMR referred to below, one of whom will serve

as lead independent director. Subject to applicable law, prior to the Merger, Messrs. Horton and Parker will engage in a planning process for integration purposes.

AMR and US Airways have each made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants (i) to conduct their businesses in the ordinary and usual course between the execution of the Merger Agreement and the consummation of the Merger and (ii) not to solicit alternative business combination transactions. In addition, the Merger Agreement contains “no shop” provisions that restrict each party's ability to initiate, solicit or knowingly encourage or facilitate competing third-party proposals for any transaction involving a merger of such party or the acquisition of a significant portion of its stock or assets, although each party may consider competing, unsolicited proposals and enter into discussions or negotiations regarding such proposals, if its board of directors determines that any such acquisition proposal constitutes, or is reasonably likely to lead to, a superior proposal and that the failure to take such action is reasonably likely to be inconsistent with its fiduciary duties under applicable law.

US Airways has agreed to certain additional customary covenants in the Merger Agreement, including, among others, subject to certain exceptions, (i) to cause a stockholder meeting to be held to consider adoption of the Merger Agreement and (ii) for its board of directors to recommend adoption of the Merger Agreement by US Airways' stockholders. AMR has also agreed to certain additional customary covenants in the Merger Agreement, including, among others, subject to certain exceptions, (i) to pursue confirmation of the Plan and (ii) for its board of directors to recommend adoption of the Merger Agreement by the Debtors' stakeholders.

Consummation of the Merger is subject to customary conditions, including, among others: (i) approval of the stockholders of US Airways; (ii) expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the receipt of certain other regulatory approvals; (iii) absence of any order or injunction prohibiting the consummation of the Merger; (iv) Bankruptcy Court confirmation of the Plan, which must contain certain specified provisions defined in the Merger Agreement; (v) subject to certain exceptions, the accuracy of representations and warranties with respect to the business of AMR or US Airways, as applicable; (vi) each of AMR and US Airways having performed their respective obligations pursuant to the Merger Agreement; and (vii) receipt by each of the Company and US Airways of a customary tax opinion.

The Merger Agreement contains certain termination rights for AMR and US Airways, and further provides that, upon termination of the Merger Agreement under specified circumstances, (i) AMR may be required to pay US Airways a termination fee of $135 million in the event it terminates the agreement to enter into a superior proposal and $195 million if US Airways terminates the Merger Agreement in the event of a knowing and deliberate breach of the Merger Agreement by AMR and (ii) US Airways may be required to pay AMR a termination fee of $55 million in the event it terminates the agreement to enter into a superior proposal and $195 million if AMR terminates the Merger Agreement in the event of a knowing and deliberate breach of the Merger Agreement by US Airways.

Support Agreement and Term Sheet

On February 13, 2013, AMR and the other Debtors entered into a Support and Settlement Agreement (the Support Agreement) with certain holders of certain prepetition claims against one or more of the Debtors (such holders of claims, the Consenting Creditors), aggregating approximately $1.2 billion of prepetition unsecured claims. Pursuant to the terms of the Support Agreement, each Consenting Creditor has agreed, among other things, and subject to certain conditions, to (a) vote in favor of a Plan, which includes certain terms specified in a Term Sheet attached to the Support Agreement (the Term Sheet), (b) generally support confirmation and consummation of the Plan and (c) not to support or solicit any plan in opposition to the Plan. Confirmation and consummation of the Plan are subject to compliance with the provisions of the Bankruptcy Code and to the closing of the Merger.

The Support Agreement may be terminated upon the occurrence of certain events, including: (a) certain breaches by the Debtors or Consenting Creditors under the Support Agreement; (b) termination of the Merger Agreement or the announcement by AMR or US Airways of their intent to terminate the Merger Agreement (in which case the Support Agreement would terminate automatically); (c) the failure to meet certain milestones with respect to achieving confirmation and consummation of the Plan; (d) the filing, amendment or modification of certain documents, including the Plan, in a manner materially inconsistent with the Support Agreement and materially adverse to a Consenting Creditor (in which case the Support Agreement can be terminated by such Consenting Creditor solely with respect to itself); (e) the amendment or modification of the Merger Agreement in a manner that is materially adverse to a Consenting Creditor (in which case the Support Agreement can be terminated by such Consenting Creditor solely with respect to itself); and (f) if the volume weighted average price of US Airways' common stock for the thirty trading days ending on the last trading day immediately prior to the date of termination is less than $10.40. Termination of the Support Agreement would give the Consenting Creditors the right to withdraw their support of the Plan.

As described in the Term Sheet, the Plan implements the Merger, incorporates a compromise and settlement of certain intercreditor and intercompany claim issues, and is to contain the following provisions relating to the treatment of prepetition unsecured claims against the Debtors and equity interests in AMR:

•

Unless they elect to receive alternative treatment, holders of prepetition unsecured claims against AMR or American that also are guaranteed by either such company (Double-Dip Unsecured Claims) will receive shares of preferred stock of New American (the New American Preferred Stock) that will be mandatorily convertible into shares of New American Common Stock on each of the 30th, 60th, 90th and 120th day after the effective date of the Plan. Upon the conversion of the New American Preferred Stock on the 120th day after the effective date of the Plan, all New American Preferred Stock will have been converted to New American Common Stock and no New American Preferred Stock will remain outstanding. The conversion price of the New American Preferred Stock will vary on each conversion date, based on the volume weighted average price of the shares of the New American Common Stock on the five trading days immediately preceding each conversion date, at a 3.5% discount, subject to a cap and a floor price. The New American Preferred Stock allocable to the Double-Dip Unsecured Claims will have a face amount equal to the allowed amount of their claims, including post-petition interest at the non-default rate;


•	Holders of prepetition unsecured claims that are not Double-Dip Unsecured Claims (and holders of Double-Dip Unsecured Claims that elect to receive such treatment) will receive shares of New American Preferred Stock, as well as shares of New American Common Stock;


•	Holders of existing AMR equity interests (including stock, warrants, restricted stock units and options) will receive a distribution of shares of New American Common Stock representing 3.5% of the total number of shares of New American Common Stock (on an as-converted basis) in addition to the potential to receive shares of New American Common Stock above such amount; and


•	The satisfaction of certain labor-related claims through the allocation to such claims of shares of New American Common Stock representing 23.6% of the total number of such shares of New American Common Stock ultimately distributed to holders of prepetition general unsecured creditors against the Debtors.

In each case, the distributions made to each of the foregoing stakeholders will be adjusted to take into account any reserves made for disputed claims under the Plan.

- Definition

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
