Dividends on the Class J Depositary Shares are cumulative and payable quarterly in arrears at the rate of 5.50% per annum based on the $25.00 per share initial offering price, or $1.375 per annum. The Class J Depositary Shares are redeemable, in whole or part, for cash on or after July 25, 2017, at the option of the Company, at a redemption price of $25.00 per depositary share, plus any accrued and unpaid dividends thereon. The Class J Depositary Shares are not convertible or exchangeable for any other property or securities of the Company. The net proceeds received from this offering of $217.8 million, after expenses, are for the redemption of all the outstanding depositary shares representing the Company’s Class F preferred stock, as discussed below and for general corporate purposes, including the potential redemption of additional classes of the Company’s preferred stock when they become redeemable at our option. On July 16, 2012, the Company called for the redemption of all of its outstanding 7,000,000 depositary shares of the Company’s 6.65% Class F Cumulative Redeemable Preferred Stock, $1.00 par value per share (the “Class F Preferred Stock”). The aggregate redemption amount of $175.0 million, before payment of accrued and unpaid dividends of $1.0 million, is scheduled to be paid on August 15, 2012. The Company will record a charge of $6.2 million resulting from the difference between the redemption amount and the carrying amount of the Class F Preferred Stock on the Company’s Condensed Consolidated Balance Sheets in accordance with the FASB’s guidance on Distinguishing Liabilities from Equity.
