tax purposes. You should consult your tax advisors as to the availability and desirability of a mark-to-market election, as well as the impact of such election on

taxpayer identification number and makes any other required certification or who otherwise establishes an exemption from backup withholding. U.S. Holders who are required to establish their exempt status generally must provide such certification on
Internal Revenue Service Form W-9. U.S. Holders should
