 and other applicable guidance thereunder, commonly referred to as “FATCA,” generally impose a U.S. federal withholding tax of 30% on any U.S.-source interest paid on debt obligations if paid to a “foreign financial institution” or a “non-financial foreign entity” (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary) unless: (i) in the case of a foreign financial institution, such institution enters into an agreement with the U.S. government to withhold on certain payments, and to collect and provide to the U.S. tax authorities information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners); (ii) the non-financial foreign entity either certifies it does not have any “substantial U.S. owners” or furnishes identifying information regarding each substantial U.S. owner; or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as an IRS Form W-8BEN-E). An applicable intergovernmental agreement regarding FATCA between the United States and a foreign jurisdiction may modify the rules discussed in this paragraph. Proposed U.S. Treasury regulations would eliminate the requirement under FATCA in respect of withholding on gross proceeds from sales, exchanges or dispositions of debt obligations (including the bonds), and the preamble to the proposed regulations provides that taxpayers and withholding agents may rely on these proposed regulations pending their finalization.

Holders should consult their tax advisors regarding the implications of FATCA on their investment in the bonds.

The U.S. federal income tax discussion set forth above is included for general information only and may not be applicable depending upon a holder’s particular situation. Holders should consult their tax advisors regarding the tax consequences to them of the purchase, ownership and disposition of bonds, including the tax consequences under state, local, foreign and other tax laws.**
