 FATCA generally applies to payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019. However, pursuant to proposed Treasury regulations (upon which taxpayers may
generally rely until applicable final regulations are issued or such proposed Treasury regulations are rescinded), gross proceeds from the sale or other disposition of a note will not be subject to withholding under FATCA. Prospective investors
should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in the notes.
