Such requests must be received by the Plan Administrator at least three business days prior to the payment date of a dividend in order to be effective with respect to that dividend. CERTAIN U.S. FEDERAL INCOME TAX INFORMATION The following is a brief summary of certain U.S. federal income tax consequences to a U.S. person (a “U.S. Participant”) of participation in the Plan. It is based on the Internal Revenue Code of 1986, as amended, administrative pronouncements and judicial decisions, all as in effect on the date of this prospectus supplement and all subject to change or differing interpretations, possibly with retroactive effect. This summary does not address all of the tax consequences that may be relevant to a participant in light of the participant’s particular circumstances or to participants that are subject to special rules.

TABLE OF CONTENTS

The tax basis of shares of common stock acquired with reinvested dividends generally will equal the fair market value of the shares on the related dividend payment date, plus, if shares are acquired through an open market purchase, the amount of any brokerage commissions and fees allocable to such shares. The holding period for shares of common stock generally will begin on the day following the related dividend payment date.

| 28. | How are the backup withholding tax provisions generally applied to U.S. Participants? |

Backup withholding tax is not an additional tax. A U.S. Participant subject to the backup withholding tax rules will be allowed a credit of the amount withheld against such U.S. Participant’s U.S. federal income tax liability and, if backup withholding tax results in an overpayment of U.S. federal income tax, such U.S. Participant may be entitled to a refund, provided
