Stockholders' Equity Note [Abstract]

SHAREHOLDERS’ EQUITY

SHAREHOLDERS’ EQUITY

We have a Dividend Reinvestment Plan (the “Plan”), whereby shareholders may use their dividends and optional cash payments to purchase shares. In 2012, 2011 and 2010, 22,814 shares, 28,823 shares and 34,401 shares, respectively, were issued under the Plan.

As of December 31, 2012, 2011, and 2010, we had 399,896 shares of 5.417% Series 1 Cumulative Convertible Preferred Shares (“Series 1 Preferred Shares”) outstanding that have a liquidation preference of $25 per share and

par value $0.01 per share. The Series 1 Preferred Shares accrue dividends at a rate of 5.417% per year and are convertible at any time by the holders to our common shares at a conversion rate of $104.69 per share. The Series 1 Preferred Shares are also convertible under certain circumstances at our election. The holders of the Series 1 Preferred Shares have no voting rights.

On May 8, 2012, we replaced our existing at the market (“ATM”) equity program with a new program in which we may from time to time offer and sell common shares having an aggregate offering price of up to $300.0 million. We intend to use the net proceeds to fund potential acquisition opportunities, fund our development and redevelopment pipeline, repay amounts outstanding under our revolving credit facility and/or for general corporate purposes. For the year ended December 31, 2012, we issued 1,040,946 common shares at a weighted average price per share of $103.69 for net cash proceeds of $106.4 million and paid $1.4 million in commissions related to the sales of these common shares. For the year ended December 31, 2011, we issued 1,662,038 common shares at a weighted average price per share of $85.26 for net cash proceeds of $139.3 million and paid $2.1 million in commissions related to the sales of these common shares. As of December 31, 2012, we had the capacity to issue up to $213.4 million in common shares under our ATM equity program.
