Subsequent Events	Subsequent Events PSP2 On January 15, 2021 (the PSP2 Closing Date), the Subsidiaries entered into a Payroll Support Program Extension Agreement (the PSP2 Agreement) with Treasury, with respect to PSP2 provided pursuant to the PSP Extension Law. In connection with our entry into the PSP2 Agreement, on the PSP2 Closing Date, AAG also entered into a warrant agreement (the PSP2 Warrant Agreement) with Treasury and issued the PSP2 Promissory Note to Treasury, with the Subsidiaries as guarantors. PSP2 Agreement In connection with PSP2, we are required to comply with the relevant provisions of the PSP Extension Law, which are substantially similar as the restrictions contained in the PSP1 Agreement, but are in effect for a longer time period. These provisions include the requirement that funds provided pursuant to the PSP2 Agreement be used exclusively for the continuation of payment of eligible employee wages, salaries and benefits, the requirement against involuntary furloughs and reductions in employee pay rates and benefits through March 31, 2021, the provisions that prohibit the repurchase of AAG common stock, and the payment of common stock dividends through at least March 31, 2022, the provisions that restrict the payment of certain executive compensation until October 1, 2022, as well as a requirement to recall employees involuntarily terminated or furloughed after September 30, 2020. As was the case with PSP1, the PSP2 Agreement also imposes substantial reporting obligations on us. Pursuant to the PSP2 Agreement, Treasury is to provide us financial assistance to be paid in installments (each, an Installment) expected to total at least $3.0 billion in the aggregate, of which $1.5 billion was received on January 15, 2021. As partial compensation to the U.S. Government for the provision of financial assistance under PSP2, and assuming a total principal sum of approximately $3.0 billion, we expect AAG to issue a PSP2 Promissory Note in the aggregate principal amount of approximately $896 million and issue warrants (each a PSP2 Warrant and, collectively, the PSP2 Warrants) to Treasury to purchase up to an aggregate of approximately 5.7 million shares of AAG common stock. PSP2 Promissory Note As partial compensation to the U.S. Government for the provision of financial assistance under the PSP2 Agreement, AAG issued the PSP2 Promissory Note to Treasury, which provides for our unconditional promise to pay to Treasury the initial principal sum of approximately $433 million, subject to an increase equal to 30% of the amount of each additional Installment disbursed under the PSP2 Agreement after the PSP2 Closing Date, and the guarantee of the Company’s obligations by the Subsidiaries. Assuming the total Installments to be paid pursuant to the PSP2 Agreement aggregate approximately $3.0 billion, the PSP2 Promissory Note will have a total principal sum of approximately $896 million. The PSP2 Promissory Note bears interest on the outstanding principal amount at a rate equal to 1.00% per annum until the fifth anniversary of the PSP2 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 PSP2 Closing Date (the PSP2 Maturity Date), and interest accrued thereon will be payable in arrears on the last business day of March and September of each year, beginning on March 31, 2021. The aggregate principal amount outstanding under the PSP2 Promissory Note, together with all accrued and unpaid interest thereon and all other amounts payable under the PSP2 Promissory Note, will be due and payable on the PSP2 Maturity Date. We may, at any time and from time to time, voluntarily prepay amounts outstanding under the PSP2 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 PSP2 Promissory Note at such time, together with any accrued interest or other amounts owing under the PSP2 Promissory Note at such time. The PSP2 Promissory Note is our senior unsecured obligation and each guarantee of the PSP2 Promissory Note is the senior unsecured obligation of each of the Subsidiaries, respectively. The PSP2 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 PSP2 Promissory Note may, and in certain circumstances will automatically, be accelerated and become due and payable immediately. PSP2 Warrant Agreement and PSP2 Warrants As partial compensation to the U.S. Government for the provision of financial assistance under the PSP2 Agreement, and pursuant to the PSP2 Warrant Agreement, AAG agreed to issue warrants to Treasury to purchase PSP2 Warrant Shares. The exercise price of the PSP2 Warrant Shares is $15.66 per share (which was the closing price of the AAG common stock on The Nasdaq Global Select Market on December 24, 2020), subject to certain anti-dilution provisions provided for in the PSP2 Warrants. Pursuant to the PSP2 Warrant Agreement, (a) on the PSP2 Closing Date, AAG issued to Treasury a PSP2 Warrant to purchase up to an aggregate of approximately 2.8 million shares of Common Stock based on the terms described herein and (b) on the date of each increase of the principal amount of the PSP2 Promissory Note in connection with the disbursement of an additional Installment under the PSP2 Agreement, AAG will issue to Treasury an additional PSP2 Warrant for a number of shares of AAG common stock equal to 10% of such increase of the principal amount of the PSP2 Promissory Note, divided by $15.66, the exercise price of such shares. Assuming the total Installments to be paid pursuant to the PSP2 Agreement aggregate approximately $3.0 billion, the total number of PSP2 Warrant Shares issuable is approximately 5.7 million, subject to certain anti-dilution provisions, provided for in the PSP2 Warrants. The PSP2 Warrants do not have any voting rights and are freely transferrable, with registration rights. Each PSP2 Warrant expires on the fifth anniversary of the date of issuance of such PSP2 Warrant. The PSP2 Warrants will be exercisable either through net share settlement or cash, at our option. The PSP2 Warrants were and will be issued solely as compensation to the U.S. Government related to entry into the PSP2 Agreement. No separate proceeds (apart from the financial assistance described above) were received upon issuance of the PSP2 Warrants or will be received upon exercise thereof. At the Market Offering On October 22, 2020, AAG entered into an Equity Distribution Agreement (Prior ATM) relating to the issuance and sale of shares of AAG common stock pursuant to an at-the-market offering up to an aggregate value of $1.0 billion. Since the inception of the Prior ATM through January 28, 2021, we issued 68.6 million shares of AAG common stock at an average price of $12.87 per share for net proceeds of $869 million. We provided notice to terminate the Prior ATM effective as of January 28, 2021 with $118 million of shares of AAG common stock available for issuance. On January 29, 2021, AAG entered into a new Equity Distribution Agreement (ATM Offering) relating to the issuance and sale of shares of AAG common stock pursuant to an at-the-market offering up to an aggregate value of $1.1 billion. The net proceeds from the sale of shares of AAG common stock related to the ATM Offering will be used for general corporate purposes and to enhance our liquidity position. Since the inception of the ATM Offering through February 16, 2021, we have issued 18.2 million shares of AAG common stock at an average price of $17.59 per share for proceeds of $320 million.

PSP2 Agreement

In connection with PSP2, we are required to comply with the relevant provisions of the PSP Extension Law, which are substantially similar as the restrictions contained in the PSP1 Agreement, but are in effect for a longer time period. These provisions include the requirement that funds provided pursuant to the PSP2 Agreement be used exclusively for the continuation of payment of eligible employee wages, salaries and benefits, the requirement against involuntary furloughs and reductions in employee pay rates and benefits through March 31, 2021, the provisions that prohibit the repurchase of AAG common stock, and the payment of common stock dividends through at least March 31, 2022, the provisions that restrict the payment of certain executive compensation until October 1, 2022, as well as a requirement to recall employees involuntarily terminated or furloughed after September 30, 2020.
