11. Shareholders' Equity

On April 20, 2011, we sold 7,000,000 6.875% Series J Cumulative Redeemable Preferred Shares at a price of $25.00 per share, in an underwritten public offering pursuant to an effective registration statement. On April 21, 2011, the underwriters exercised their option to purchase an additional 1,050,000 shares to cover over-allotments. On May 5, 2011, we sold an additional 800,000 sharesat a price of $25.00 per share. We retained aggregate net proceeds of $214,538,000, after underwriters' discounts and issuance costs and contributed the net proceeds to the Operating Partnership in exchange for 8,850,000 Series J Preferred Units (with economic terms that mirror those of the Series J Preferred Shares). Dividends on the Series J Preferred Shares are cumulative and payable quarterly in arrears. The Series J Preferred Shares are not convertible into, or exchangeable for, any of our properties or securities. On or after five years from the date of issuance (or sooner under limited circumstances), we, at our option, may redeem the Series J Preferred Shares at a redemption price of $25.00 per share, plus accrued and unpaid dividends through the date of redemption. The Series J Preferred Shares have no maturity date and will remain outstanding indefinitely unless redeemed by us.
