Subsequent Events	Subsequent EventsOn October 21, 2020, we entered into a Restatement Agreement (the Treasury Loan Restatement Agreement) to the Treasury Loan Agreement. The Treasury Loan Restatement Agreement increased the commitment under the Treasury Term Loan Facility to $7.5 billion, representing an increase of approximately $2.0 billion beyond the approximately $5.5 billion of commitment under the Treasury Term Loan Facility as of the date of execution of the Treasury Loan Agreement. No additional borrowing was made by American on October 21, 2020 in connection with the entry into the Treasury Loan Restatement Agreement. Due to the increase in the commitment under the Treasury Term Loan Facility to $7.5 billion, AAG may now issue up to an aggregate of approximately 60.0 million Treasury Loan Warrant Shares, assuming the Treasury Term Loan Facility, as amended by the Restatement Agreement, is fully drawn.
