and the 2042 Notes are collectively referred to in this prospectus supplement as the "Notes." The offering and sale of each series of Notes is not conditioned on the sale of any
other series of Notes.
The 2017 Notes will bear interest at a rate of 1.50% per year and will mature on November 15, 2017. The 2022 Notes will bear interest at a rate of 2.75% per year and will
