On March 14, 2017 (the “Closing Date”), American Airlines, Inc. (“American”) and American Airlines Group Inc. (“AAG”) entered into a Second Amendment to the Amended and Restated Credit and Guaranty Agreement (the “Second Amendment”), amending the Amended and Restated Credit and Guaranty Agreement dated as of May 21, 2015 (as amended prior to the date hereof, the “2015 Credit Agreement”), among American, AAG, the lenders from time to time party thereto, Deutsche Bank AG New York Branch, as administrative agent, and certain other parties thereto.

On the Closing Date, the aggregate principal amount of the term loans outstanding under the 2015 Credit Agreement (the “Existing Term Loans”) was approximately $1.8 billion. Under the Second Amendment, American refinanced the Existing Term Loans with proceeds of term loans incurred pursuant to the Second Amendment (the “2017 Replacement Term Loans”). Pursuant to the Second Amendment, the interest rate margin on the 2017 Replacement Term Loans was reduced to 2.00% for those loans with interest rates based on LIBOR (compared to 2.50% for the Existing Term Loans) and to 1.00% for loans with interest rates based on an index (compared to 1.50% for the Existing Term Loans). The revolving credit facility under the 2015 Credit Agreement remains unchanged and, as of the Closing Date, there were no borrowings or letters of credit outstanding thereunder.

See the Annual Report on Form 10-K of AAG and American for the period ended December 31, 2016 for more information regarding credit facilities established under the 2015 Credit Agreement.

The information described under Item 1.01 above “Entry into a Material Definitive Agreement” is incorporated herein by reference.
