Glossary

This prospectus supplement uses defined terms such as those found below. You can find a listing of defined terms used but not defined in this prospectus supplement in the “Glossary of Defined Terms” beginning on page 146 in the related prospectus.

“LIBOR” means, as of any LIBOR Determination Date, the rate for deposits in United States dollars for a one-month period which appears on Reuters Screen LIBOR01 Page or on such comparable system as is customarily used to quote LIBOR as of 11:00 a.m., London time, on that date. If this rate does not appear on Reuters Screen LIBOR01 Page or on a comparable system as is customarily used to quote LIBOR, the rate for that LIBOR Determination Date will be determined on the basis of the rates at which deposits in United States dollars are offered by four major banks selected by the beneficiary of the issuing entity at approximately 11:00 a.m., London time, on that day to prime banks in the London interbank market for a one-month period. The indenture trustee will request the principal London office of each of the banks to provide a quotation of its rate. If at least two quotations are provided, the rate for that LIBOR Determination Date will be the arithmetic mean of the quotations. If fewer than two quotations are provided, the rate for that LIBOR Determination Date will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the beneficiary of the issuing entity, at approximately 11:00 a.m., New York City time, on that day for loans in United States dollars to leading European banks for a one-month period.

“LIBOR Determination Date” means (1)                 , 2017 for the period from and including the issuance date through but excluding April 17, 2017 and (2) for each interest period thereafter, the second London Business Day prior to each interest payment date on which that interest period commences.

“London Business Day” means any Business Day on which dealings in deposits in United States dollars are transacted in the London interbank market.
