2018 Aircraft Financing Activities

2017-2 EETCs

During the first quarter of 2018, $210 million of the $1.0 billion total net proceeds from the issuance of certain enhanced equipment trust certificates in August and October 2017 (the 2017-2 EETCs) were used to purchase equipment notes issued by American in connection with financing 4 of the 30 aircraft financed under the 2017-2 EETCs. Approximately $735 million of proceeds from the 2017-2 EETCs were used in 2017 to purchase equipment notes issued by American in connection with the financing of 24 aircraft. Interest and principal payments on equipment notes issued in connection with the 2017-2 EETCs are payable semi-annually in April and October of each year, with interest payments beginning in April 2018 and principal payments beginning in October 2018. These equipment notes are secured by liens on the aircraft financed with the proceeds of the 2017-2 EETCs. The remaining net proceeds of $73 million of 2017-2 EETCs is being held in escrow for the benefit of the holders of the 2017-2 EETCs until such time as American issues additional Series AA, A and B equipment notes to the pass-through trusts, which will purchase additional equipment notes with the escrowed funds. These escrowed funds are not guaranteed by American and are not reported as debt on its condensed consolidated balance sheet because the proceeds held by the depository are not American's assets.

Certain information regarding the 2017-2 EETC equipment notes and the remaining escrowed proceeds of the 2017-2 EETCs, as of March 31, 2018, is set forth in the table below.
