As of February 17, 2011, there were 585 shareholders of record and approximately 19,335 beneficial owners of our common shares.

In January 2008, our Board of Trust Managers approved an increase of the April 2007 repurchase plan to allow for the repurchase of up to $500 million of our common equity securities through open market purchases, block purchases, and privately negotiated transactions. Under this program, we have repurchased 4.3 million shares for a total of approximately $230.2 million from April 2007 through December 31, 2010. The remaining dollar value of our common equity securities authorized to be repurchased under the program was approximately $269.8 million as of December 31, 2010. There were no repurchases of our equity securities during the year ended December 31, 2010.

In March 2010, we announced the creation of an at-the-market (“ATM”) share offering program through which we may, but have no obligation to, sell common shares having an aggregate offering price of up to $250 million, in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares, and determinations of the appropriate sources of funding for us. During the year ended December 31, 2010, we issued approximately 4.9 million common shares at an average price of $48.37 per share for total net consideration of approximately $231.7 million. In January 2011, we issued 0.1 million common shares at an average price of $54.06 per share for total net consideration of approximately $3.8 million. As of the date of this filing, we had common shares having an aggregate offering price of up to $10.7 million remaining available for sale under the ATM program.

See Part III, Item 12, for a description of securities authorized for issuance under equity compensation plans.
