The underwriters have advised us that they are committed to purchase all the depositary shares offered by us if they purchase any depositary shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated. The underwriters propose to offer the depositary shares directly to the public at the initial public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $0.30 per depositary share sold to institutional investors and $0.50 per depository share sold to retail investors. Any such dealers may resell depositary shares to certain other brokers or dealers at a discount of up to $0.45 per depositary share sold to retail investors from the initial public offering price. After the initial public offering of the depositary shares, the offering price and other selling terms may be changed by the underwriters. Sales of depositary shares made outside of the U.S. may be made by affiliates of the underwriters. Underwriting Discounts The underwriting fee is equal to the public offering price per depositary share less the amount paid by the underwriters to us per depositary share. The following table shows the per depositary share and total underwriting discounts to be paid to the underwriters.
