(All "section" references herein are to the Internal Revenue Code of 1986) PRIVACY ACT NOTICE -- Section 6109 requires you to furnish your correct TIN to persons who must file information returns with the IRS to report interest, dividends, and certain other income paid to you, mortgage interest you paid, the acquisition or abandonment of secured property, or contributions you made to an IRA. The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. Payers must generally withhold the applicable withholding rate of taxable interest, dividend, and certain other payments to a payee who does not furnish a TIN to a payer. Certain penalties may apply. PENALTIES (1) PENALTY FOR FAILURE TO FURNISH TIN -- If you fail to furnish your TIN to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect. (2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING-- If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500. (3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION-- Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
