Subsequent Events	Subsequent Events Dividend Declaration In October 2017, we announced that our Board of Directors had declared a $0.10 per share dividend for stockholders of record on November 13, 2017, and payable on November 27, 2017. Any future dividends that may be declared and paid from time to time will be subject to market and economic conditions, applicable legal requirements and other relevant factors. We are not obligated to continue a dividend for any fixed period, and payment of dividends may be suspended at any time at our discretion. 2016-3 Class B EETCs In October 2017, American created one additional pass-through trust which issued approximately $193 million aggregate principal amount of Series 2016-3 Class B EETCs (the 2016-3 Class B EETCs) in connection with the financing of the 2016-3 Aircraft. The proceeds received from the sale of the 2016-3 Class B EETCs were used on the date of issuance of the 2016-3 Class B EETCs to acquire Series B equipment notes issued by American in connection with the financing of the 2016-3 Aircraft. These Series B equipment notes bear interest at 3.75% per annum. Interest and principal payments on equipment notes issued in connection with the 2016-3 Class B EETCs are payable semi-annually in April and October of each year, beginning in April 2018. 2017-2 Class B EETCs In October 2017, American created one additional pass-through trust which issued approximately $221 million aggregate principal amount of Series 2017-2 Class B EETCs (the 2017-2 Class B EETCs) in connection with the financing of the 2017-2 Aircraft. A portion of the net proceeds received from the sale of the Series 2017-2 Class B EETCs was used on the date of issuance of the 2017-2 Class B EETCs to acquire Series B equipment notes issued by American in connection with the financing of certain 2017-2 Aircraft, and the balance of such proceeds is being held in escrow for the benefit of the holders of the 2017-2 Class B EETCs until such time as American issues additional Series B equipment notes to the pass-through trust, which trusts will purchase such additional equipment notes with the escrowed funds. These escrowed funds are not guaranteed by American and are not reported as debt on our condensed consolidated balance sheet because the proceeds held by the depository are not American's assets. These Series B equipment notes bear interest at 3.70% per annum. Interest and principal payments on equipment notes issued in connection with the 2017-2 Class B 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.
