Unsecured Debt	Unsecured Debt At August 31, 2016, our short-term borrowings consisted of euro- and U.S. dollar-denominated commercial paper of $246 million and $85 million, respectively, and euro-denominated bank loans of $3 million with an aggregate weighted-average floating interest rate of 0.2%. In February 2016, we issued $555 million of euro-denominated, publicly-traded notes, which bear interest at 1.625% and are due in February 2021. In April 2016, we borrowed $379 million under an export credit facility, the proceeds of which were used to pay for a portion of AIDA Cruises' (“AIDA”) AIDAprima purchase price. Of this facility, a portion bears fixed and a portion bears floating interest rates. The facility is due in semi-annual installments through August 2027. In May 2016, we entered into four export credit facilities that will provide us with the ability to borrow up to an aggregate of $2.3 billion. Proceeds from these facilities will be used to pay for a portion of the purchase price of four cruise ships, which are expected to be delivered between February 2019 and September 2020. These borrowings will be due in semi-annual installments through September 2032. In May 2016, we exercised our option to extend the termination date of our multi-currency revolving credit facility from June 2020 to June 2021. In addition, the total capacity of the revolving credit facility increased to $2.6 billion (comprised of $1.9 billion, €500 million and £169 million). In July 2016, we borrowed $110 million under a euro-denominated, floating rate bank loan, due in July 2021. In July 2016, we entered into a $168 million euro-denominated, fixed rate bank loan, which was drawn in September 2016 and is due in September 2020. In July 2016, we entered into a $100 million, floating rate bank loan, which is expected to be drawn in November 2016, and is due in November 2021. In August 2016, we canceled an export credit facility that provided us with the ability to borrow up to an aggregate of $201 million to pay for a portion of the purchase price of a Seabourn ship, which is expected to be delivered in November 2016. In August 2016, we extended the termination date of a $100 million, floating rate bank loan, from October 2016 to October 2021. We use the net proceeds from our borrowings for general corporate purposes and purchases of new ships.
