CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment. PRIVACY ACT NOTICE--Section 6109 of the IRC requires most recipients of dividend, interest, or other payments to give taxpayer identification numbers to payers who must report the payments to IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of individuals' tax returns. The IRS may also provide this information to the Department of Justice for civil and criminal litigation and to states, cities and the District of Columbia to help carry out their tax laws. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 31% of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.
