The term loans under each of the Credit Facilities are repayable in annual installments in an amount equal to 1.00% of the aggregate principal amount issued, with any unpaid balance due on the respective maturity dates. Voluntary prepayments may be made by American at any time.
The 2013 Revolving Facility, 2014 Revolving Facility and April 2016 Revolving Facility provide that American may from time to time borrow, repay and reborrow loans thereunder. The 2013 Revolving Facility and 2014 Revolving Facility have the ability to issue letters of credit thereunder in an aggregate amount outstanding at any time up to $100 million and $200 million, respectively. The 2013 Revolving Facility, 2014 Revolving Facility and April 2016 Revolving Facility are each subject to an undrawn annual fee of 0.63%.
Subject to certain limitations and exceptions, the Credit Facilities are secured by collateral, including certain spare parts, slots, route authorities, simulators and leasehold rights. American has the ability to make future modifications to the collateral pledged, subject to certain restrictions. American’s obligations under the Credit Facilities are guaranteed by AAG. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans as further described below in “Certain Covenants.”
The Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and become due and payable immediately. In addition, if a “change of control” occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the Credit Facilities and terminate the 2013 Revolving Facility, 2014 Revolving Facility and April 2016 Revolving Facility and any revolving credit facility established under the December
2016 Credit Facilities. The Credit Facilities also include covenants that, among other things, require AAG to maintain an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
Delayed Draw Term Loan Credit Facility
In March 2020, American and AAG entered into a Credit and Guaranty Agreement which provided for a $1.0 billion senior secured delayed draw term loan credit facility (the Delayed Draw Term Loan Credit Facility), which was scheduled to be due and payable in a single installment on the maturity date in March 2021. In connection with the issuance of the 11.75% senior secured notes due 2025, as described below, the Delayed Draw Term Loan Credit Facility was repaid and the Delayed Draw Term Loan Credit Facility and all of the security documents and other loan documents related thereto were terminated as of June 30, 2020.
(b) Senior Secured Notes
11.75% Senior Secured Notes
In June 2020, American issued $2.5 billion aggregate principal amount of 11.75% senior secured notes due 2025 (the 11.75% Senior Secured Notes) at a price equal to 99% of their aggregate principal amount. The 11.75% Senior Secured Notes bear interest at a rate of 11.75% per annum (subject to increase if the collateral coverage ratio described below is not met). Interest on the 11.75% Senior Secured Notes is payable semiannually in arrears on January 15 and July 15 of each year, beginning on January 15, 2021. The 11.75% Senior Secured Notes will mature on July 15, 2025. The obligations of American under the 11.75% Senior Secured Notes are fully and unconditionally guaranteed on a senior unsecured basis by AAG. The proceeds from the 11.75% Senior Secured Notes were used to repay and terminate the Delayed Draw Term Loan Credit Facility (and to terminate all security documents and all other loan documents related thereto) with the remaining amount for general corporate purposes and to enhance our liquidity position.
The 11.75% Senior Secured Notes were issued pursuant to an indenture, dated as of June 30, 2020 (the 11.75% Senior Secured Notes Indenture), by and among American, AAG and Wilmington Trust, National Association, as trustee (the 11.75% Senior Secured Notes Trustee). The 11.75% Senior Secured Notes are American’s senior secured obligations. Subject to certain limitations and exceptions, the 11.75% Senior Secured Notes are secured on a first-lien basis by security interests in certain assets, rights and properties utilized by American in providing its scheduled air carrier services to and from certain airports in the United States and certain airports in Australia, Canada, the Caribbean, Central America, China, Hong Kong, Japan, Mexico, South Korea, and Switzerland (collectively, the First Lien 11.75% Senior Secured Notes Collateral). American’s obligations with respect to the 11.75% Senior Secured Notes are also secured on a second-lien basis by security interests in certain assets, rights and properties utilized by American in providing its scheduled air carrier services to and from certain airports in the United States and certain airports in the European Union and the United Kingdom (collectively, the Second Lien 11.75% Senior Secured Notes Collateral and together with the First Lien 11.75% Senior Secured Notes Collateral, the 11.75% Senior Secured Notes Collateral). American may be required to pledge additional collateral in the future under the terms of the 11.75% Senior Secured Notes, and in certain circumstances may elect to pledge additional collateral as a replacement for existing collateral. The Second Lien 11.75% Senior Secured Notes Collateral also secures the 2014 Credit Facilities on a first-lien basis.
American may redeem the 11.75% Senior Secured Notes, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the 11.75% Senior Secured Notes being redeemed plus a make whole premium, together with accrued and unpaid interest thereon, if any, to (but not including) the redemption date.
In the event of a specified change of control, each holder of 11.75% Senior Secured Notes may require American to repurchase its 11.75% Senior Secured Notes in whole or in part at a repurchase price of 101% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if any, to (but not including) the repurchase date.
American is required to deliver an appraisal of the First Lien 11.75% Senior Secured Notes Collateral and officer’s certificate on a semi-annual basis demonstrating the calculation of a collateral coverage ratio in relation to the First Lien 11.75% Senior Secured Notes Collateral as of the end of each semi-annual period based on such appraisal. If American fails to deliver the officer’s certificate in a timely manner or the collateral coverage ratio is less than 1.6 to 1.0 as of the end of the semi-annual period, then, subject to an opportunity to cure the deficiency in the collateral coverage ratio, American will be required to pay special interest in an additional amount equal to 2.0% per annum of the outstanding principal amount of the 11.75% Senior Secured Notes until the collateral coverage ratio is established to be at least 1.6 to 1.0.
The 11.75% Senior Secured Notes Indenture contains covenants that, among other things, restrict the ability of AAG and the ability of its restricted subsidiaries (including American) to: (i) pay dividends, redeem or repurchase stock or make other distributions or restricted payments, (ii) incur liens on the 11.75% Senior Secured Notes Collateral and dispose of or release the 11.75% Senior Secured Notes Collateral, (iii) repay subordinated indebtedness, (iv) make certain loans and investments, (v) incur indebtedness or issue preferred stock, (vi) merge, consolidate or sell assets, (vii) undergo certain change of control transactions, and (viii) designate subsidiaries as unrestricted. These covenants are subject to a number of important exceptions and qualifications set forth in the 11.75% Senior Secured Notes Indenture.
Upon the occurrence of any event of default (other than certain bankruptcy or insolvency or reorganization events affecting AAG or certain of its subsidiaries, including American), the 11.75% Senior Secured Notes may be declared to be due and payable immediately. Upon the occurrence of certain bankruptcy, insolvency or reorganization events affecting American or certain of its subsidiaries (including American), all outstanding 11.75% Senior Secured Notes will become due and payable immediately without further action or notice on the part of the 11.75% Senior Secured Notes Trustee or any holder of the 11.75% Senior Secured Notes.
10.75% Senior Secured Notes
On September 25, 2020 (the 10.75% Senior Secured Notes Closing Date), American issued $1.0 billion in initial principal amount of senior secured IP notes (the IP Notes) and $200 million in initial principal amount of senior secured LGA/DCA notes (the LGA/DCA Notes and together with the IP Notes, the 10.75% Senior Secured Notes). The obligations of American under the 10.75% Senior Secured Notes are fully and unconditionally guaranteed (the 10.75% Senior Secured Notes Guarantees) on a senior unsecured basis by AAG. The 10.75% Senior Secured Notes bear interest at a rate of 10.75% per annum in cash. For any interest period on or prior to September 1, 2022, American may, at its election, pay interest at a rate of 12.00% per annum payable one-half in cash and one-half in kind. Interest on the 10.75% Senior Secured Notes is payable semiannually in arrears on September 1 and March 1 of each year, beginning on March 1, 2021. The 10.75% Senior Secured Notes will mature on February 15, 2026.
The proceeds from the 10.75% Senior Secured Notes were used to pay transaction-related fees and expenses and for general corporate purposes.
The 10.75% Senior Secured Notes were each issued pursuant to a separate indenture, dated as of September 25, 2020 (individually, the IP Notes Indenture and the LGA/DCA Notes Indenture and collectively, the 10.75% Senior Secured Notes Indentures), by and among American, AAG and Wilmington Trust, National Association, as trustee and as collateral trustee (the 10.75% Senior Secured Notes Trustee). The IP Notes are secured by a first lien security interest on certain intellectual property of American, including the “American Airlines” trademark and the “aa.com” domain name in the United States and certain foreign jurisdictions (the IP Collateral), and a second lien on certain slots related to American’s operations at New York LaGuardia and Ronald Reagan Washington National airports and certain other assets (the LGA/DCA Collateral and together with the IP Collateral, the 10.75% Senior Secured Notes Collateral). Subject to certain conditions, American will be permitted to incur up to $4.0 billion of additional pari passu debt and unlimited second lien debt secured by the IP Collateral securing the IP Notes. The LGA/DCA Notes are secured by a first lien security interest in the LGA/DCA Collateral. American may be required to pledge additional collateral in the future under the terms of the 10.75% Senior Secured Notes, and in certain circumstances may elect to pledge additional collateral including as a replacement for existing collateral. The LGA/DCA Collateral also secures on a first-lien basis the December 2016 Credit Facilities.
On or prior to the fourth anniversary of the 10.75% Senior Secured Notes Closing Date, American may redeem all or any part of the 10.75% Senior Secured Notes, at its option, at a redemption price equal to 100% of the principal amount of the 10.75% Senior Secured Notes redeemed plus a make whole premium, together with accrued and unpaid interest thereon, if any. After the fourth anniversary of the 10.75% Senior Secured Notes Closing Date and on or prior to the fifth anniversary of the 10.75% Senior Secured Notes Closing Date, American may redeem all or any part of the 10.75% Senior Secured Notes, at its option, at a redemption price equal to 105.375% of the principal amount of the 10.75% Senior
Secured Notes redeemed, together with accrued and unpaid interest thereon, if any. After the fifth anniversary of the 10.75% Senior Secured Notes Closing Date, American may redeem all or any part of the 10.75% Senior Secured Notes, at its option, at par, together with accrued and unpaid interest thereon, if any.
In the event of a specified change of control, each holder of 10.75% Senior Secured Notes may require American to repurchase its 10.75% Senior Secured Notes, in whole or in part, at a repurchase price of 101% of the aggregate principal amount of the 10.75% Senior Secured Notes so repurchased, plus accrued and unpaid interest thereon, if any, to (but not including) the repurchase date.
The 10.75% Senior Secured Notes Indentures contain covenants that, among other things, restrict the ability of AAG and the ability of its restricted subsidiaries (including American) to: (i) pay dividends, redeem or repurchase stock or make other distributions or restricted payments, (ii) incur liens on the 10.75% Senior Secured Notes Collateral and dispose of or release the 10.75% Senior Secured Notes Collateral, (iii) repay subordinated indebtedness, (iv) make certain loans and investments, (v) incur indebtedness or issue preferred stock, (vi) merge, consolidate or sell assets, and (vii) designate subsidiaries as unrestricted. In addition, the 10.75% Senior Secured Notes Indentures include covenants that require AAG to maintain (a) an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities and (b) a certain minimum ratio of appraised value of the collateral to outstanding debt secured thereby on a first lien basis as further described below in “Certain Covenants.” These covenants are subject to a number of important exceptions and qualifications set forth in the 10.75% Senior Secured Notes Indentures.
Upon the occurrence of any event of default (other than certain bankruptcy or insolvency or reorganization events affecting AAG or certain of its subsidiaries, including American), the 10.75% Senior Secured Notes may be declared to be due and payable immediately. Upon the occurrence of certain bankruptcy, insolvency or reorganization events affecting AAG or certain of its subsidiaries (including American), all outstanding 10.75% Senior Secured Notes will become due and payable immediately without further action or notice on the part of the 10.75% Senior Secured Notes Trustee or any holder of the 10.75% Senior Secured Notes.
(c) Treasury Loan Agreement
On September 25, 2020, American and AAG entered into a Loan and Guarantee Agreement (the Treasury Loan Agreement) with Treasury, which provided for a secured term loan facility (the Treasury Term Loan Facility) that permitted American to borrow up to $5.5 billion. Subsequently, on October 21, 2020, American and AAG entered into an amendment to the Treasury Loan Agreement, which increased the borrowing amount to up to $7.5 billion.
As of December 31, 2020, American had borrowed $550 million under the Treasury Term Loan Facility and may, at its option, borrow additional amounts in up to two subsequent borrowings until March 26, 2021. Subsequently, on January 15, 2021, American and AAG entered into an amendment to the Treasury Loan Agreement, which extended this deadline to May 28, 2021. The proceeds from the Treasury Term Loan Facility were, and will be, used for certain general corporate purposes and operating expenses in accordance with the terms and conditions of the Treasury Loan Agreement and the applicable provisions of the CARES Act.
The Treasury Term Loan Facility bears interest at a variable rate per annum equal to (a)(i) the LIBOR rate divided by (ii) one minus the Eurodollar Reserve Percentage plus (b) 3.50%. Accrued interest on the loans will be payable in arrears on the first business day following the 14th day of each March, June, September and December, beginning with September 15, 2021, and on June 30, 2025 (the Treasury Term Loan Maturity Date). As of December 31, 2020, the applicable interest rate for the $550 million loan drawn under the Treasury Term Loan Facility was 3.73% per annum through September 15, 2021, at which time the interest rate will reset.
All advances under the Treasury Term Loan Facility will be in the form of term loans, all of which will mature and be due and payable in a single installment on the Treasury Term Loan Maturity Date. American may, at any time and from time to time, voluntarily prepay amounts outstanding under the Treasury Loan Agreement, in whole or in part, without penalty or premium. Amounts prepaid may not be reborrowed. Mandatory prepayments of loans under the Treasury Term Loan Facility are required, without penalty or premium, to the extent necessary to comply with American's covenants regarding the expiry of certain agreements constituting Treasury Collateral (as defined below), the debt service coverage ratio, certain dispositions of Treasury Collateral, certain debt issuances secured by liens on the Treasury Collateral and certain indemnity, termination, liquidated damages or insurance payments related to the Treasury Collateral, in addition to the occurrence of a change in control of AAG.
American's obligations under the Treasury Loan Agreement are secured by a first priority security interest on American's rights under U.S. co-branded credit card agreements and certain other loyalty program partner participation agreements (including rights to receive cash flows thereunder), documents, deposit accounts, securities accounts, books and records and intellectual property related to American's AAdvantage loyalty program and all proceeds, accessions, rents or profits related to the foregoing (collectively, the Treasury Collateral). American is permitted under the Treasury Loan Agreement to add certain types of assets to the Treasury Collateral and, subject to certain conditions, release Treasury Collateral, in each case from time to time at its discretion.
The Treasury Loan Agreement requires American, under certain circumstances, including within 10 business days prior to the last business day of March and September of each year, beginning March 2021, to appraise the value of the Treasury Collateral and recalculate the collateral coverage ratio. If the calculated collateral coverage ratio is less than 1.6 to 1.0, American will be required either to provide additional Treasury Collateral (which may include cash collateral) to secure its obligations under the Treasury Loan Agreement or repay the term loans under the Treasury Term Loan Facility, in such amounts that the recalculated collateral coverage ratio, after giving effect to any such additional Treasury Collateral or repayment, is at least 1.6 to 1.0.
The Treasury Loan Agreement also requires American to calculate the debt service coverage ratio on a quarterly basis. If the calculated debt service coverage ratio is less than 1.75 to 1.00, then AAG and its subsidiaries will be required to place an amount equal to at least 50% of certain revenues received from the AAdvantage loyalty program (the Loyalty Program Revenues) into a blocked account to be held for the benefit of the lenders who may choose to use such funds to prepay the outstanding term loans until the debt service coverage ratio is recalculated to be greater than or equal to 1.75 to 1.00. If the calculated debt service coverage ratio is less than or equal to 1.50 to 1.00, but greater than 1.25 to 1.00, then all amounts previously deposited into the blocked account will be used to prepay outstanding term loans and an amount equal to at least 50% of all future Loyalty Program Revenues will be transferred into the payment account and used to prepay outstanding term loans until the debt service coverage ratio is recalculated to be greater than 1.50 to 1.00. If the calculated debt service coverage ratio is less than or equal to 1.25 to 1.00, then all amounts previously deposited into the blocked account will be used to prepay outstanding term loans and an amount equal to at least 75% of all future Loyalty Program Revenues will be transferred into the payment account and used to prepay outstanding term loans until the debt service coverage ratio is recalculated to be greater than 1.25 to 1.00.
The Treasury Loan Agreement also includes affirmative, negative and financial covenants that, among other things, limit AAG's ability to pay dividends, repurchase common stock of AAG or make certain other payments, make certain investments, incur liens on the Treasury Collateral, dispose of the Treasury Collateral, amend material AAdvantage loyalty program agreements, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions. In addition, under the Treasury Loan Agreement, AAG must maintain a minimum aggregate liquidity of $2.0 billion.
The Treasury Loan Agreement requires AAG and American to comply with the relevant provisions of the CARES Act and the Treasury Loan Agreement, including, but not limited to, the provisions that prohibit the repurchase of AAG’s common stock, the payment of common stock dividends and those that restrict the payment of certain executive compensation, in each case, through the date that is 12 months after the date on which all amounts of loan outstanding under the Treasury Term Loan Facility have been repaid in full.
The Treasury Loan Agreement contains events of default, including cross-default with respect to acceleration or failure to pay at maturity other material indebtedness. Upon the occurrence of an event of default and subject to certain grace periods, the outstanding obligations under the Treasury Loan Agreement may be accelerated and become due and payable immediately.

In August 2019, American created three pass-through trusts which issued approximately $1.1 billion aggregate face amount of Series 2019-1 Class AA, Class A and Class B EETCs (the 2019-1 Aircraft EETCs) in connection with the financing of 35 aircraft (the 2019-1 Aircraft). In 2019, $804 million of the proceeds had been used to purchase equipment notes issued by American in connection with the financing of 28 aircraft under the 2019-1 Aircraft EETCs, of which $608 million was used to repay existing indebtedness. In 2020, the remaining $293 million of the proceeds had been used to purchase equipment notes issued by American in connection with the financing of seven aircraft under the 2019-1 Aircraft EETCs. Interest and principal payments on equipment notes issued in connection with the 2019-1 Aircraft EETCs are payable semiannually in February and August of each year, which interest payments began in February 2020 and which
principal payments began or are scheduled to begin (i) in the case of equipment notes with respect to any 2019-1 Aircraft owned by American at the time of issuance of the 2019-1 Aircraft EETCs, in February 2020 and (ii) in the case of equipment notes with respect to the Embraer 175 aircraft and the Airbus A321neo aircraft scheduled to be delivered after the issuance of the 2019-1 Aircraft EETCs, in August 2020 and August 2021, respectively.
Certain information regarding the 2019-1 Aircraft EETC equipment notes, as of December 31, 2020, is set forth in the table below.

(e) Equipment Loans and Other Notes Payable Issued in 2020
In 2020, American entered into agreements under which it borrowed $307 million in connection with the financing or refinancing, as the case may be, of certain aircraft and other flight equipment, of which $17 million was used to repay existing indebtedness. Debt incurred under these agreements matures in 2029 through 2032 and bears interest at variable rates (comprised of LIBOR plus an applicable margin) averaging 2.28% at December 31, 2020.
(f) Special Facility Revenue Bonds Issued in 2020
In January 2020, American and British Airways announced the start of construction on a $344 million investment to upgrade New York's John F. Kennedy International Airport (JFK) Terminal 8.
In June 2020, the New York Transportation Development Corporation (NYTDC) issued approximately $360 million of special facility revenue bonds (the 2020 JFK Bonds) on behalf of American. A portion of the net proceeds from the 2020 JFK Bonds have been or will be used to fund costs of issuance of the 2020 JFK Bonds, to fund a substantial portion of the cost of the renovation and expansion of a passenger terminal facility (the Terminal) leased and utilized by American at JFK and to fund the August 2020 maturity of the outstanding bonds issued by NYTDC on behalf of American in 2016 (the 2016 JFK Bonds).
American is required to pay debt service on the 2020 JFK Bonds through payments under a loan agreement with NYTDC (as amended), and American and AAG guarantee the 2020 JFK Bonds. American continues to pay debt service on the outstanding 2016 JFK Bonds and American and AAG continue to guarantee the 2016 JFK Bonds. American’s and AAG’s obligations under these guarantees are secured by a leasehold mortgage on American’s lease of the Terminal and related property from the Port Authority of New York and New Jersey.
The 2020 JFK Bonds, in aggregate, were priced at approximately 98% of par value. The gross proceeds from the issuance of the 2020 JFK Bonds were approximately $353 million. Of this amount, approximately $8 million was used to fund the costs of issuance of the 2020 JFK Bonds, approximately $47 million was used to fund the redemption of the 2016 JFK Bonds due August 2020 and approximately $17 million was reimbursed to American for the Terminal construction costs incurred, with the remaining amount of proceeds received to be held in restricted cash and short-term investments on the consolidated balance sheet and to be used to finance a substantial portion of the cost of the renovation and expansion of the Terminal. The 2020 JFK Bonds are comprised of term bonds, $214 million of which bear interest at 5.25% per annum and mature on August 1, 2031, and $146 million of which bear interest at 5.375% per annum and mature on August 1, 2036.
(g) PSP1 Promissory Note
In April 2020, as partial compensation to the U.S. Government for the provision of financial assistance under the PSP1 Agreement, AAG issued the PSP1 Promissory Note to Treasury, which provides for our unconditional promise to pay to Treasury 30% of the total amount of financial assistance disbursed under the PSP1 Agreement, and the guarantee of our obligations by the Subsidiaries. The total financial assistance we received pursuant to the PSP1 Agreement is approximately $6.0 billion. As of December 31, 2020, the principal amount of the PSP1 Promissory Note was approximately $1.8 billion.
The PSP1 Promissory Note bears interest on the outstanding principal amount at a rate equal to 1.00% per annum until the fifth anniversary of the PSP1 Closing Date and 2.00% plus an interest rate based on the secured overnight financing rate per annum or other benchmark replacement rate consistent with customary market conventions (but not to be less than 0.00%) thereafter until the tenth anniversary of the PSP1 Closing Date (the PSP1 Maturity Date), and interest accrued thereon will be payable in arrears on the last business day of March and September of each year, which began on September 30, 2020. The aggregate principal amount outstanding under the PSP1 Promissory Note, together with all accrued and unpaid interest thereon and all other amounts payable under the PSP1 Promissory Note, will be due and payable on the PSP1 Maturity Date.
We may, at any time and from time to time, voluntarily prepay amounts outstanding under the PSP1 Promissory Note, in whole or in part, without penalty or premium. Within 30 days of the occurrence of certain change of control triggering events, we are required to prepay the aggregate outstanding principal amount of the PSP1 Promissory Note at such time, together with any accrued interest or other amounts owing under the PSP1 Promissory Note at such time.
The PSP1 Promissory Note is our senior unsecured obligation and each guarantee of the PSP1 Promissory Note is the senior unsecured obligation of each of the Subsidiaries, respectively.
The PSP1 Promissory Note contains events of default, including cross-default with respect to acceleration or failure to pay at maturity other material indebtedness. Upon the occurrence of an event of default and subject to certain grace periods, the outstanding obligations under the PSP1 Promissory Note may, and in certain circumstances will automatically, be accelerated and become due and payable immediately.
(h) 6.50% Convertible Senior Notes
In June 2020, AAG completed the public offering of $1.0 billion aggregate principal amount of AAG’s 6.50% convertible senior notes due 2025 (the Convertible Notes). The Convertible Notes are fully and unconditionally guaranteed by American on a senior unsecured basis (the Convertible Notes Guarantee). The net proceeds to us from the Convertible Notes were approximately $970 million, after deducting the underwriters’ discounts and commissions and our estimated offering expenses. The net proceeds from the Convertible Notes are being used for general corporate purposes and to enhance our liquidity position. The Convertible Notes were priced to investors in the offering at 100% of their principal amount.
The Convertible Notes were issued pursuant to an indenture, dated as of June 25, 2020 (the Base Indenture), between AAG and Wilmington Trust, National Association as trustee (the Convertible Notes Trustee), as supplemented by that certain first supplemental indenture, dated as of June 25, 2020, among AAG, American and the Convertible Notes Trustee (the Convertible Notes Supplemental Indenture and, together with the Base Indenture, the Convertible Notes Indenture). The Convertible Notes bear interest at a rate of 6.50% per annum. Interest on the Convertible Notes is payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2021. The Convertible Notes will mature on July 1, 2025, unless earlier converted or redeemed or repurchased by us.
Upon conversion, AAG will pay or deliver, as the case may be, cash, shares of AAG common stock or a combination of cash and shares of AAG common stock, at AAG’s election. The initial conversion rate is 61.7284 shares of AAG common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $16.20 per share of AAG common stock). The conversion rate is subject to adjustment in some events as described in the Convertible Notes Indenture.
Holders may convert their Convertible Notes at their option only in the following circumstances: (1) during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending on September 30, 2020, if the last reported sale price per share of AAG common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the measurement period) in which the trading price per $1,000 principal amount of Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of AAG common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on AAG common stock; (4) if AAG calls such Convertible Notes for redemption; and (5) at any time from, and including, April 1, 2025 until the close of business on the scheduled trading day immediately before the maturity date of the Convertible Notes.
In addition, following certain corporate events that occur prior to the maturity date or upon AAG’s issuance of a notice of redemption, AAG will increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such corporate event or during the related redemption period in certain circumstances by a specified number of shares of AAG common stock as described in the Convertible Notes Indenture.
AAG will not have the right to redeem the Convertible Notes prior to July 5, 2023. On or after July 5, 2023 and on or before the 20th scheduled trading day immediately before the maturity date, AAG may redeem the Convertible Notes, in whole or in part, if the last reported sale price of AAG common stock has been at least 130% of the conversion price then in effect on (1) each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the trading day immediately before the date AAG sends the related redemption notice; and (2) the trading day immediately before the date AAG sends such notice. In the case of any optional redemption, AAG will redeem the Convertible Notes at a redemption price equal to 100% of the principal amount of such Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.
If AAG undergoes a fundamental change described in the Convertible Notes Indenture prior to the maturity date of the Convertible Notes, except as described in the Convertible Notes Indenture, holders of the Convertible Notes may require AAG to repurchase for cash all or part of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.
The Convertible Notes Indenture provides for customary terms and covenants, including that upon certain events of default, either the Convertible Notes Trustee or the holders of not less than 25% in aggregate principal amount of the Convertible Notes then outstanding may declare the unpaid principal amount of the Convertible Notes and accrued and unpaid interest, if any, thereon immediately due and payable. In the case of certain events of bankruptcy, insolvency or reorganization, the principal amount of the Convertible Notes together with accrued and unpaid interest thereon, if any, will automatically become and be immediately due and payable.
As the Convertible Notes can be settled in cash upon conversion, for accounting purposes, the Convertible Notes were bifurcated into a debt component that was recorded at fair value and an equity component. The following table details the debt and equity components recognized related to the Convertible Notes as of December 31, 2020 (in millions):
December 31, 2020
Principal amount of 6.50% convertible senior notes$1,000 
Unamortized debt discount(417)
Net carrying amount of 6.50% convertible senior notes583 
Additional paid-in capital415 
The effective interest rate on the liability component approximates 20%. We recognized $61 million of interest expense in 2020 including $28 million of non-cash amortization of the debt discount and $33 million of contractual coupon interest. The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is five years as follows: $63 million in 2021, $77 million in 2022, $95 million in 2023, $116 million in 2024 and $66 million in 2025. As previously discussed in Note 1(c), as of January 1, 2021, we early adopted the New Convertible Debt Standard. Accordingly, our unamortized debt discount as of January 1, 2021 was reduced by $389 million and the adjusted non-cash interest expense to be recognized over the next five years is as follows: $5 million in 2021, $6 million in 2022, $6 million in 2023, $7 million in 2024 and $4 million in 2025.
At December 31, 2020, the if-converted value of the Convertible Notes did not exceed the principal amount.
(i) Unsecured Senior Notes
5.000% Senior Notes
In May 2019, AAG issued $750 million aggregate principal amount of 5.000% senior notes due 2022 (the 5.000% Senior Notes). The 5.000% Senior Notes bear interest at a rate of 5.000% per annum, payable semi-annually in arrears on June 1 and December 1 of each year, which began on December 1, 2019. The 5.000% Senior Notes mature in June 2022.
3.75% Senior Notes
In February 2020, AAG issued $500 million aggregate principal amount of 3.75% senior notes due 2025 (the 3.75% Senior Notes). The 3.75% Senior Notes bear interest at a rate of 3.75% per annum, payable semiannually in arrears in March and September of each year, which began in September 2020. The 3.75% Senior Notes mature in March 2025.
The details of our 5.000% and 3.75% Senior Notes are shown in the table below as of December 31, 2020:

Fixed interest rate per annum5.000%3.75%
Interest paymentsSemi-annually in arrears in June and DecemberSemi-annually in arrears in March and September
The 5.000% and 3.75% Senior Notes are senior unsecured obligations of AAG. These Senior Notes are fully and unconditionally guaranteed by American. The indentures for these Senior Notes contain covenants and events of default generally customary for similar financings. In addition, if we experience specific kinds of changes of control, we must offer to repurchase these Senior Notes in whole or in part at a price of 101% of the principal amount plus accrued and unpaid interest thereon, if any, to (but not including) the repurchase date. Upon the occurrence of certain events of default, these Senior Notes may be accelerated and become due and payable.
Guarantees
As of December 31, 2020, AAG had issued guarantees covering approximately $15.0 billion of American’s secured debt (and interest thereon), including the Credit Facilities and certain EETC financings and $1.0 billion of American’s special facility revenue bonds (and interest thereon).
Certain Covenants
Certain of our debt financing agreements (including our secured notes, term loans, revolving credit facilities and spare engine EETCs) contain loan to value (LTV) or collateral coverage ratio covenants and require us to appraise the related collateral annually or semiannually. Pursuant to such agreements, if the LTV or collateral coverage ratio exceeds a specified threshold or if the value of the appraised collateral fails to meet a specified threshold, as the case may be, we are required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash or investment securities), or pay down such financing, in whole or in part, or the interest rate for the financing under such agreements will be increased. Additionally, a significant portion of our debt financing agreements contain covenants requiring us to maintain an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities, and our Treasury Term Loan Facility contains a debt service coverage ratio, pursuant to which failure to comply with a certain threshold may result in mandatory prepayment of the Treasury Term Loan Facility.
Specifically, we are required to meet certain collateral coverage tests for our Credit Facilities, 10.75% Senior Secured Notes, 11.75% Senior Secured Notes and Treasury Loan Agreement, as described below:

The term loans under each of the Credit Facilities are repayable in annual installments in an amount equal to 1.00% of the aggregate principal amount issued, with any unpaid balance due on the respective maturity dates. Voluntary prepayments may be made by American at any time.
The 2013 Revolving Facility, 2014 Revolving Facility and April 2016 Revolving Facility provide that American may from time to time borrow, repay and reborrow loans thereunder. The 2013 Revolving Facility and 2014 Revolving Facility have the ability to issue letters of credit thereunder in an aggregate amount outstanding at any time up to $100 million and $200 million, respectively. The 2013 Revolving Facility, 2014 Revolving Facility and April 2016 Revolving Facility are each subject to an undrawn annual fee of 0.63%.
Subject to certain limitations and exceptions, the Credit Facilities are secured by collateral, including certain spare parts, slots, route authorities, simulators and leasehold rights. American has the ability to make future modifications to the collateral pledged, subject to certain restrictions. American’s obligations under the Credit Facilities are guaranteed by AAG. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans as further described below in “Certain Covenants.”
The Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and become due and payable immediately. In addition, if a “change of control” occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the Credit Facilities and terminate the 2013 Revolving Facility, 2014 Revolving Facility and April 2016 Revolving Facility and any revolving credit facility established under the December 2016 Credit Facilities. The Credit Facilities also include covenants that, among other things, require AAG to maintain an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
Delayed Draw Term Loan Credit Facility
In March 2020, American and AAG entered into a Credit and Guaranty Agreement which provided for a $1.0 billion senior secured delayed draw term loan credit facility (the Delayed Draw Term Loan Credit Facility), which was scheduled to be due and payable in a single installment on the maturity date in March 2021. In connection with the issuance of the 11.75% senior secured notes due 2025, as described below, the Delayed Draw Term Loan Credit Facility was repaid and the Delayed Draw Term Loan Credit Facility and all of the security documents and other loan documents related thereto were terminated as of June 30, 2020.
(b) Senior Secured Notes
11.75% Senior Secured Notes
In June 2020, American issued $2.5 billion aggregate principal amount of 11.75% senior secured notes due 2025 (the 11.75% Senior Secured Notes) at a price equal to 99% of their aggregate principal amount. The 11.75% Senior Secured Notes bear interest at a rate of 11.75% per annum (subject to increase if the collateral coverage ratio described below is not met). Interest on the 11.75% Senior Secured Notes is payable semiannually in arrears on January 15 and July 15 of each year, beginning on January 15, 2021. The 11.75% Senior Secured Notes will mature on July 15, 2025. The obligations of American under the 11.75% Senior Secured Notes are fully and unconditionally guaranteed on a senior unsecured basis by AAG. The proceeds from the 11.75% Senior Secured Notes were used to repay and terminate the Delayed Draw Term Loan Credit Facility (and to terminate all security documents and all other loan documents related thereto) with the remaining amount for general corporate purposes and to enhance American’s liquidity position.
The 11.75% Senior Secured Notes were issued pursuant to an indenture, dated as of June 30, 2020 (the 11.75% Senior Secured Notes Indenture), by and among American, AAG and Wilmington Trust, National Association, as trustee (the 11.75% Senior Secured Notes Trustee). The 11.75% Senior Secured Notes are American’s senior secured obligations. Subject to certain limitations and exceptions, the 11.75% Senior Secured Notes are secured on a first-lien basis by security interests in certain assets, rights and properties utilized by American in providing its scheduled air carrier services to and from certain airports in the United States and certain airports in Australia, Canada, the Caribbean, Central America, China, Hong Kong, Japan, Mexico, South Korea, and Switzerland (collectively, the First Lien 11.75% Senior Secured Notes Collateral). American’s obligations with respect to the 11.75% Senior Secured Notes are also secured on a second-lien basis by security interests in certain assets, rights and properties utilized by American in providing its scheduled air carrier services to and from certain airports in the United States and certain airports in the European Union and the United Kingdom (collectively, the Second Lien 11.75% Senior Secured Notes Collateral and together with the First Lien 11.75% Senior Secured Notes Collateral, the 11.75% Senior Secured Notes Collateral). American may be required to pledge additional collateral in the future under the terms of the 11.75% Senior Secured Notes, and in certain circumstances may elect to pledge additional collateral as a replacement for existing collateral. The Second Lien 11.75% Senior Secured Notes Collateral also secures the 2014 Credit Facilities on a first-lien basis.
American may redeem the 11.75% Senior Secured Notes, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the 11.75% Senior Secured Notes being redeemed plus a make whole premium, together with accrued and unpaid interest thereon, if any, to (but not including) the redemption date.
In the event of a specified change of control, each holder of 11.75% Senior Secured Notes may require American to repurchase its 11.75% Senior Secured Notes in whole or in part at a repurchase price of 101% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if any, to (but not including) the repurchase date.
American is required to deliver an appraisal of the First Lien 11.75% Senior Secured Notes Collateral and officer’s certificate on a semi-annual basis demonstrating the calculation of a collateral coverage ratio in relation to the First Lien 11.75% Senior Secured Notes Collateral as of the end of each semi-annual period based on such appraisal. If American fails to deliver the officer’s certificate in a timely manner or the collateral coverage ratio is less than 1.6 to 1.0 as of the end of the semi-annual period, then, subject to an opportunity to cure the deficiency in the collateral coverage ratio, American will be required to pay special interest in an additional amount equal to 2.0% per annum of the outstanding principal amount of the 11.75% Senior Secured Notes until the collateral coverage ratio is established to be at least 1.6 to 1.0.
The 11.75% Senior Secured Notes Indenture contains covenants that, among other things, restrict the ability of AAG and the ability of its restricted subsidiaries (including American) to: (i) pay dividends, redeem or repurchase stock or make other distributions or restricted payments, (ii) incur liens on the 11.75% Senior Secured Notes Collateral and dispose of or release the 11.75% Senior Secured Notes Collateral, (iii) repay subordinated indebtedness, (iv) make certain loans and investments, (v) incur indebtedness or issue preferred stock, (vi) merge, consolidate or sell assets, (vii) undergo certain change of control transactions, and (viii) designate subsidiaries as unrestricted. These covenants are subject to a number of important exceptions and qualifications set forth in the 11.75% Senior Secured Notes Indenture.
Upon the occurrence of any event of default (other than certain bankruptcy or insolvency or reorganization events affecting AAG or certain of its subsidiaries, including American), the 11.75% Senior Secured Notes may be declared to be due and payable immediately. Upon the occurrence of certain bankruptcy, insolvency or reorganization events affecting American or certain of its subsidiaries (including American), all outstanding 11.75% Senior Secured Notes will become due and payable immediately without further action or notice on the part of the 11.75% Senior Secured Notes Trustee or any holder of the 11.75% Senior Secured Notes.
10.75% Senior Secured Notes
On September 25, 2020 (the 10.75% Senior Secured Notes Closing Date), American issued $1.0 billion in initial principal amount of senior secured IP notes (the IP Notes) and $200 million in initial principal amount of senior secured LGA/DCA notes (the LGA/DCA Notes and together with the IP Notes, the 10.75% Senior Secured Notes). The obligations of American under the 10.75% Senior Secured Notes are fully and unconditionally guaranteed (the 10.75% Senior Secured Notes Guarantees) on a senior unsecured basis by AAG. The 10.75% Senior Secured Notes bear interest at a rate of 10.75% per annum in cash. For any interest period on or prior to September 1, 2022, American may, at its election, pay interest at a rate of 12.00% per annum payable one-half in cash and one-half in kind. Interest on the 10.75% Senior Secured Notes is payable semiannually in arrears on September 1 and March 1 of each year, beginning on March 1, 2021. The 10.75% Senior Secured Notes will mature on February 15, 2026.
The proceeds from the 10.75% Senior Secured Notes were used to pay transaction-related fees and expenses and for general corporate purposes.
The 10.75% Senior Secured Notes were each issued pursuant to a separate indenture, dated as of September 25, 2020 (individually, the IP Notes Indenture and the LGA/DCA Notes Indenture and collectively, the 10.75% Senior Secured Notes Indentures), by and among American, AAG and Wilmington Trust, National Association, as trustee and as collateral trustee (the 10.75% Senior Secured Notes Trustee). The IP Notes are secured by a first lien security interest on certain intellectual property of American, including the “American Airlines” trademark and the “aa.com” domain name in the United States and certain foreign jurisdictions (the IP Collateral), and a second lien on certain slots related to American’s operations at New York LaGuardia and Ronald Reagan Washington National airports and certain other assets (the LGA/DCA Collateral and together with the IP Collateral, the 10.75% Senior Secured Notes Collateral). Subject to certain conditions, American will be permitted to incur up to $4.0 billion of additional pari passu debt and unlimited second lien debt secured by the IP Collateral securing the IP Notes. The LGA/DCA Notes are secured by a first lien security interest in the LGA/DCA Collateral. American may be required to pledge additional collateral in the future under the terms of the 10.75% Senior Secured Notes, and in certain circumstances may elect to pledge additional collateral including as a replacement for existing collateral. The LGA/DCA Collateral also secures on a first-lien basis the December 2016 Credit Facilities.
On or prior to the fourth anniversary of the 10.75% Senior Secured Notes Closing Date, American may redeem all or any part of the 10.75% Senior Secured Notes, at its option, at a redemption price equal to 100% of the principal amount of the 10.75% Senior Secured Notes redeemed plus a make whole premium, together with accrued and unpaid interest thereon, if any. After the fourth anniversary of the 10.75% Senior Secured Notes Closing Date and on or prior to the fifth anniversary of the 10.75% Senior Secured Notes Closing Date, American may redeem all or any part of the 10.75% Senior Secured Notes, at its option, at a redemption price equal to 105.375% of the principal amount of the 10.75% Senior Secured Notes redeemed, together with accrued and unpaid interest thereon, if any. After the fifth anniversary of the 10.75% Senior Secured Notes Closing Date, American may redeem all or any part of the 10.75% Senior Secured Notes, at its option, at par, together with accrued and unpaid interest thereon, if any.
In the event of a specified change of control, each holder of 10.75% Senior Secured Notes may require American to repurchase its 10.75% Senior Secured Notes, in whole or in part, at a repurchase price of 101% of the aggregate principal amount of the 10.75% Senior Secured Notes so repurchased, plus accrued and unpaid interest thereon, if any, to (but not including) the repurchase date.
The 10.75% Senior Secured Notes Indentures contain covenants that, among other things, restrict the ability of AAG and the ability of its restricted subsidiaries (including American) to: (i) pay dividends, redeem or repurchase stock or make other distributions or restricted payments, (ii) incur liens on the 10.75% Senior Secured Notes Collateral and dispose of or release the 10.75% Senior Secured Notes Collateral, (iii) repay subordinated indebtedness, (iv) make certain loans and investments, (v) incur indebtedness or issue preferred stock, (vi) merge, consolidate or sell assets, and (vii) designate subsidiaries as unrestricted.

Upon the occurrence of any event of default (other than certain bankruptcy or insolvency or reorganization events affecting AAG or certain of its subsidiaries, including American), the 10.75% Senior Secured Notes may be declared to be due and payable immediately. Upon the occurrence of certain bankruptcy, insolvency or reorganization events affecting AAG or certain of its subsidiaries (including American), all outstanding 10.75% Senior Secured Notes will become due and payable immediately without further action or notice on the part of the 10.75% Senior Secured Notes Trustee or any holder of the 10.75% Senior Secured Notes.
(c) Treasury Loan Agreement
On September 25, 2020, American and AAG entered into a Loan and Guarantee Agreement (the Treasury Loan Agreement) with Treasury, which provided for a secured term loan facility (the Treasury Term Loan Facility) that permitted American to borrow up to $5.5 billion. Subsequently, on October 21, 2020, American and AAG entered into an amendment to the Treasury Loan Agreement, which increased the borrowing amount to up to $7.5 billion.
As of December 31, 2020, American had borrowed $550 million under the Treasury Term Loan Facility and may, at its option, borrow additional amounts in up to two subsequent borrowings until March 26, 2021. Subsequently, on January 15, 2021, American and AAG entered into an amendment to the Treasury Loan Agreement, which extended this deadline to May 28, 2021. The proceeds from the Treasury Term Loan Facility were, and will be, used for certain general corporate purposes and operating expenses in accordance with the terms and conditions of the Treasury Loan Agreement and the applicable provisions of the CARES Act.
The Treasury Term Loan Facility bears interest at a variable rate per annum equal to (a)(i) the LIBOR rate divided by (ii) one minus the Eurodollar Reserve Percentage plus (b) 3.50%. Accrued interest on the loans will be payable in arrears on the first business day following the 14th day of each March, June, September and December, beginning with September 15, 2021, and on June 30, 2025 (the Treasury Term Loan Maturity Date). As of December 31, 2020, the applicable interest rate for the $550 million loan drawn under the Treasury Term Loan Facility was 3.73% per annum through September 15, 2021, at which time the interest rate will reset.
All advances under the Treasury Term Loan Facility will be in the form of term loans, all of which will mature and be due and payable in a single installment on the Treasury Term Loan Maturity Date. American may, at any time and from time to time, voluntarily prepay amounts outstanding under the Treasury Loan Agreement, in whole or in part, without penalty or premium. Amounts prepaid may not be reborrowed. Mandatory prepayments of loans under the Treasury Term Loan Facility are required, without penalty or premium, to the extent necessary to comply with American's covenants regarding the expiry of certain agreements constituting Treasury Collateral (as defined below), the debt service coverage ratio, certain dispositions of Treasury Collateral, certain debt issuances secured by liens on the Treasury Collateral and certain indemnity, termination, liquidated damages or insurance payments related to the Treasury Collateral, in addition to the occurrence of a change in control of AAG.
American's obligations under the Treasury Loan Agreement are secured by a first priority security interest on American's rights under U.S. co-branded credit card agreements and certain other loyalty program partner participation agreements (including rights to receive cash flows thereunder), documents, deposit accounts, securities accounts, books and records and intellectual property related to American's AAdvantage loyalty program and all proceeds, accessions, rents or profits related to the foregoing (collectively, the Treasury Collateral). American is permitted under the Treasury Loan Agreement to add certain types of assets to the Treasury Collateral and, subject to certain conditions, release Treasury Collateral, in each case from time to time at its discretion.
The Treasury Loan Agreement requires American, under certain circumstances, including within 10 business days prior to the last business day of March and September of each year, beginning March 2021, to appraise the value of the Treasury Collateral and recalculate the collateral coverage ratio. If the calculated collateral coverage ratio is less than 1.6 to 1.0, American will be required either to provide additional Treasury Collateral (which may include cash collateral) to secure its obligations under the Treasury Loan Agreement or repay the term loans under the Treasury Term Loan Facility, in such amounts that the recalculated collateral coverage ratio, after giving effect to any such additional Treasury Collateral or repayment, is at least 1.6 to 1.0.
The Treasury Loan Agreement also requires American to calculate the debt service coverage ratio on a quarterly basis. If the calculated debt service coverage ratio is less than 1.75 to 1.00, then AAG and its subsidiaries will be required to place an amount equal to at least 50% of certain revenues received from the AAdvantage loyalty program (the Loyalty Program Revenues) into a blocked account to be held for the benefit of the lenders who may choose to use such funds to prepay the outstanding term loans until the debt service coverage ratio is recalculated to be greater than or equal to 1.75 to 1.00. If the calculated debt service coverage ratio is less than or equal to 1.50 to 1.00, but greater than 1.25 to 1.00, then all amounts previously deposited into the blocked account will be used to prepay outstanding term loans and an amount equal to at least 50% of all future Loyalty Program Revenues will be transferred into the payment account and used to prepay outstanding term loans until the debt service coverage ratio is recalculated to be greater than 1.50 to 1.00. If the calculated debt service coverage ratio is less than or equal to 1.25 to 1.00, then all amounts previously deposited into the blocked account will be used to prepay outstanding term loans and an amount equal to at least 75% of all future Loyalty Program Revenues will be transferred into the payment account and used to prepay outstanding term loans until the debt service coverage ratio is recalculated to be greater than 1.25 to 1.00.
The Treasury Loan Agreement also includes affirmative, negative and financial covenants that, among other things, limit AAG's ability to pay dividends, repurchase common stock of AAG or make certain other payments, make certain investments, incur liens on the Treasury Collateral, dispose of the Treasury Collateral, amend material AAdvantage loyalty program agreements, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions. In addition, under the Treasury Loan Agreement, AAG must maintain a minimum aggregate liquidity of $2.0 billion.
The Treasury Loan Agreement requires AAG and American to comply with the relevant provisions of the CARES Act and the Treasury Loan Agreement, including, but not limited to, the provisions that prohibit the repurchase of AAG’s common stock, the payment of common stock dividends and those that restrict the payment of certain executive compensation, in each case, through the date that is 12 months after the date on which all amounts of loan outstanding under the Treasury Term Loan Facility have been repaid in full.
The Treasury Loan Agreement contains events of default, including cross-default with respect to acceleration or failure to pay at maturity other material indebtedness. Upon the occurrence of an event of default and subject to certain grace periods, the outstanding obligations under the Treasury Loan Agreement may be accelerated and become due and payable immediately.
(d) EETCs
2019-1 Aircraft EETCs
In August 2019, American created three pass-through trusts which issued approximately $1.1 billion aggregate face amount of Series 2019-1 Class AA, Class A and Class B EETCs (the 2019-1 Aircraft EETCs) in connection with the financing of 35 aircraft (the 2019-1 Aircraft). In 2019, $804 million of the proceeds had been used to purchase equipment notes issued by American in connection with the financing of 28 aircraft under the 2019-1 Aircraft EETCs, of which $608 million was used to repay existing indebtedness. In 2020, the remaining $293 million of the proceeds had been used to purchase equipment notes issued by American in connection with the financing of seven aircraft under the 2019-1 Aircraft EETCs. Interest and principal payments on equipment notes issued in connection with the 2019-1 Aircraft EETCs are payable semiannually in February and August of each year, which interest payments began in February 2020 and which principal payments began or are scheduled to begin (i) in the case of equipment notes with respect to any 2019-1 Aircraft owned by American at the time of issuance of the 2019-1 Aircraft EETCs, in February 2020 and (ii) in the case of equipment notes with respect to the Embraer 175 aircraft and the Airbus A321neo aircraft scheduled to be delivered after the issuance of the 2019-1 Aircraft EETCs, in August 2020 and August 2021, respectively.
Certain information regarding the 2019-1 Aircraft EETC equipment notes, as of December 31, 2020, is set forth in the table below.

(e) Equipment Loans and Other Notes Payable Issued in 2020
In 2020, American entered into agreements under which it borrowed $307 million in connection with the financing or refinancing, as the case may be, of certain aircraft and other flight equipment, of which $17 million was used to repay existing indebtedness. Debt incurred under these agreements matures in 2029 through 2032 and bears interest at variable rates (comprised of LIBOR plus an applicable margin) averaging 2.28% at December 31, 2020.
(f) Special Facility Revenue Bonds Issued in 2020
In January 2020, American and British Airways announced the start of construction on a $344 million investment to upgrade New York's John F. Kennedy International Airport (JFK) Terminal 8.
In June 2020, the New York Transportation Development Corporation (NYTDC) issued approximately $360 million of special facility revenue bonds (the 2020 JFK Bonds) on behalf of American. A portion of the net proceeds from the 2020 JFK Bonds have been or will be used to fund costs of issuance of the 2020 JFK Bonds, to fund a substantial portion of the cost of the renovation and expansion of a passenger terminal facility (the Terminal) leased and utilized by American at JFK and to fund the August 2020 maturity of the outstanding bonds issued by NYTDC on behalf of American in 2016 (the 2016 JFK Bonds).
American is required to pay debt service on the 2020 JFK Bonds through payments under a loan agreement with NYTDC (as amended), and American and AAG guarantee the 2020 JFK Bonds. American continues to pay debt service on the outstanding 2016 JFK Bonds and American and AAG continue to guarantee the 2016 JFK Bonds. American’s and AAG’s obligations under these guarantees are secured by a leasehold mortgage on American’s lease of the Terminal and related property from the Port Authority of New York and New Jersey.
The 2020 JFK Bonds, in aggregate, were priced at approximately 98% of par value. The gross proceeds from the issuance of the 2020 JFK Bonds were approximately $353 million. Of this amount, approximately $8 million was used to fund the costs of issuance of the 2020 JFK Bonds, approximately $47 million was used to fund the redemption of the 2016 JFK Bonds due August 2020 and approximately $17 million was reimbursed to American for the Terminal construction costs incurred, with the remaining amount of proceeds received to be held in restricted cash and short-term investments on the consolidated balance sheet and to be used to finance a substantial portion of the cost of the renovation and expansion of the Terminal. The 2020 JFK Bonds are comprised of term bonds, $214 million of which bear interest at 5.25% per annum and mature on August 1, 2031, and $146 million of which bear interest at 5.375% per annum and mature on August 1, 2036.
Guarantees
As of December 31, 2020, American had issued guarantees covering AAG’s $1.8 billion aggregate principal amount of the PSP1 Promissory Note due April 2030, $1.0 billion aggregate principal amount of 6.50% convertible senior notes due July 2025, $750 million aggregate principal amount of 5.000% senior notes due June 2022 and $500 million aggregate principal amount of 3.75% senior notes due March 2025.
Certain Covenants
Certain of American’s debt financing agreements (including its secured notes, term loans, revolving credit facilities and spare engine EETCs) contain loan to value (LTV) or collateral coverage ratio covenants and require American to appraise the related collateral annually or semiannually. Pursuant to such agreements, if the LTV or collateral coverage ratio exceeds a specified threshold or if the value of the appraised collateral fails to meet a specified threshold, as the case may be, American is required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash or investment securities), or pay down such financing, in whole or in part, or the interest rate for the financing under such agreements will be increased. Additionally, a significant portion of American’s debt financing agreements contain covenants requiring it to maintain an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities, and its Treasury Term Loan Facility contains a debt service coverage ratio, pursuant to which failure to comply with a certain threshold may result in mandatory prepayment of the Treasury Term Loan Facility.
Specifically, American is required to meet certain collateral coverage tests for its Credit Facilities, 10.75% Senior Secured Notes, 11.75% Senior Secured Notes and Treasury Loan Agreement, as described below:
