As noted above, withholding under FATCA can apply to payments of gross proceeds from the
sale or other disposition of a note, in addition to interest payments. However, Treasury regulations have been proposed that would entirely eliminate FATCA withholding on payments of gross proceeds. Taxpayers generally may rely on these proposed

Prospective investors should
consult their own tax advisors regarding FATCA and whether it may be relevant to the acquisition, ownership and disposition of notes.
