Irish Taxes Applicable to Dividends

Irish income tax may arise with respect to dividends paid on Eaton shares. Generally, shareholders who are not tax residents of Ireland and otherwise have no connection with Ireland other than his or her shareholding in Eaton, will not be subject to Irish income tax. However, in certain circumstances, Eaton will be required to deduct Irish dividend withholding tax (“IDWT”, currently at the rate of 20%) from dividends paid to its shareholders who are not Irish residents. In the majority of cases though, shareholders resident in the U.S. and certain other countries are exempt from IDWT. To establish exempt status, shareholders who qualify can complete certain Irish dividend withholding tax exemption forms or hold their shares in an account through the Depository Trust Company and have on file with their broker or qualifying agent a valid U.S. address on the record date of the dividend.

Eaton shareholders who receive their dividends subject to Irish dividend withholding tax will generally have no further liability for Irish income tax on the dividends unless they are otherwise subject to Irish income tax.
